Hundreds of connections between different human diseases have been uncovered through their shared origin in our genome by an international research team led by scientists from the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge, challenging the categorisation of diseases by organ, symptoms, or clinical speciality.

A new study published in Science today generated data on thousands of proteins circulating in our blood and combined this with genetic data to produce a map showing how genetic differences that affect these proteins link together seemingly diverse as well as related diseases.

Proteins are essential functional units of the human body that are composed of amino acids and coded for by our genes. Malfunctions of proteins cause diseases across most medical specialties and organ systems, and proteins are also the most common target of drugs that exist today.

The findings published today help explain why seemingly unrelated symptoms can occur at the same time in patients and suggest that we should reconsider how diverse diseases can be caused by the same underlying protein or mechanism. Where a protein is a drug target, this information can point to new strategies for treating a variety of conditions, as well as minimising adverse effects.

In the study using blood samples from over 10,000 participants from the Fenland study, the team led by senior author Dr Claudia Langenberg at the MRCEpidemiology Unit and Berlin Institute of Health at Charit Universittsmedizin, Germany, demonstrated that natural variation in 2,500 regions of the human genome is very robustly associated with differences in abundance or function of 5,000 proteins circulating in the blood.

This approach addresses an important bottleneck in the translation of basic science to clinically actionable insights. While large scale studies of the human genome have identified many thousands of variants in our DNA sequence that are associated with disease, underlying mechanisms remain often poorly understood due to uncertainties in mapping those variants to genes. By linking such disease-related DNA variations to the abundance or function of an encoded protein, the team produced strong evidence for which genes are involved, and identified novel mechanisms by which proteins mediate genetic risk into disease onset.

For example, multiple genome-wide association studies (GWAS) have linked a region of the human genome known as KAT8 with Alzheimers disease but failed to identify which gene in this region was involved. By combining data on both proteins and genes the team was able to identify a gene in the KAT8 region named PRSS8, which codes for the protein prostasin, as a novel candidate gene in Alzheimers disease. Similarly, they identified a novel risk gene for endometrial cancer (RSPO3).

The authors used these new insights to systematically test which of these protein-encoding genes affected a large range of diseases. They discovered more than 1,800 examples in which more than one disease was driven by variations in an individual gene and its protein products. What emerged was a network-like structure of human diseases, because many of the genes connected a range of seemingly diverse as well as related conditions in different tissues. This provides strong evidence that the respective protein is the origin, and points to new potential strategies for treatment.

Dr Langenberg explained:

An extreme example we discovered of how one protein can be connected to several diseases is the protein Fibulin-3, which we connected to 37 conditions, including hypermobility, hernias, varicose veins, and a lower risk of carpal tunnel syndrome. A likely explanation is atypical formation of elastic fibres covering our organs and joints, leading to differences in elasticity of soft and connective tissues. This is also in line with features that others have observed in mice where this gene was deleted.

Dr Maik Pietzner, a researcher at the MRC Epidemiology Unit and co-lead author of the study, added:

Using our genome as the basis was key to the success of this study. Because we know that most of the proteins detected in blood have their origin in cells from other tissues, we integrated different biological layers, like gene expression, to enable us to traceproteins back to disease-relevant tissues. For example, we found that higher activity of the enzyme bile salt sulfotransferase was associated with an increased risk of gall stones through a liver specific mechanism. We linked around 900 proteins to their tissue of origin in this way.

In collaboration with colleagues at the Helmholtz Centre in Munich, Germany, the authors have developed a bespoke web application (www.omicscience.org) to enable immediate dissemination of the results, and allow researchers worldwide to dive deeply into information on genes, proteins and diseases they are most interested in.

Dr Eleanor Wheeler, also at the MRC Epidemiology Unit and co-lead author of the study, concluded:

For most genomic regions associated with disease risk, the underlying causal gene and mechanism are not known. Our work demonstrates the distinctive value of proteins to zoom in on the causal gene for a disease and helps us to understand the mechanism through which genetic variation can cause disease. We envisage that the large amount of information we are sharing with the scientific community will help ongoing and emerging efforts to connect genes to diseases more directly via the encoded protein, thus facilitating accelerated identification of drug targets.

Do We Have a Right to Know Our Biological Parents? – The Atlantic

Posted: October 16, 2021 at 2:10 am

Damian Adams grew up knowing that his parents had used an anonymous sperm donor to conceive him, and as a teen, he was even proud of this identity. He considered donating to help other families have children. Becoming a father himself, however, changed everything. When his daughter was born 18 years ago, he cradled her in his arms, and he instantly saw himself in her and her in himself. He felt a biological connection so powerful that it made him reconsider his entire life up until then. What Id had there with my daughter, he says, was one thing I had been missing in my life. He felt the need to know where he came from.

Adams, a biologist in Australia, would spend years searching for his biological father, running into one dead end after another. Meanwhile, he also began campaigning to end donor anonymity for others like him. In 2016, he and fellow activists pushed the state of Victoria to retroactively abolish anonymity for all sperm donors. (A previous law had already banned it from 1998 onward.) Donor-conceived people in the United Kingdom have also successfully campaigned to ban anonymous sperm donation. In the United States, where anonymous donation is still technically offered, some donor-conceived people are asserting a right to know their genetic origins and even to contact their biological parents, who may or may not welcome the surprise.

All of this was unimaginable a few decades ago. Doctors used to routinely advise parents to keep the use of a sperm donor secreteven from their own childrenand this silence reinforced a sense of shame about the practice. Today, parents are strongly encouraged to tell the truth; moreover, DNA tests mean they couldnt hide it even if they wanted to. As more people find out they are donor-conceived, they are in turn finding one another: They are gathering in online communities such as We Are Donor Conceived and other Facebook support groups catering to a mix of donors, parents, donor-conceived people, and others who have learned that their parents are not who they thought they were. There are also several podcasts, at least two magazines, and even training courses for therapists who work with people in this situation. The shared identity that connects this online community is small by proportion but large in raw numbers. An estimated 30,000 to 60,000 children conceived with donor sperm are born in the U.S. every year, though that statistic may well be an underestimate. The fertility industry doesnt have to keep records, so the true number is unknown.

In learning more about their own conception, some donor-conceived people have been shocked by the lack of transparency in the industry that created them. They have been disturbed to find, in some cases, that they have dozens of half siblings from the same donor, that doctors have secretly impregnated patients with their own sperm, or that donors have lied about themselves to sperm banksall at least partially because donation was anonymous. Now donor-conceived people like Adams are questioning the need for any secrecy at all. In a forthcoming book called Uprooted, Peter Boni, who learned he was donor-conceived at age 49, lays out a Donor-Conceived Bill of Rights that demands, first and foremost, the end of anonymous donations and includes access to a donors medical records, limits on the number of offspring per donor, and consequences for outright fertility fraud. Can you point to any federal law, Boni asked me rhetorically, that protects the rights of the donor-conceived child?

Indeed, the agreements around sperm donations were originally forged among donors, parents, and doctors. Fast-forward a few decades and the childrennow adultsare trying to change a fertility industry that sees them as neither its customers nor its patients, even though it is directly responsible for their existence. The issues raised might apply to both sperm and egg donation alike, though historically, the focus has been on sperm donation because its much more common. As donor-conceived people advocate for new rights today, they are also forcing society to confront a more fundamental question, one left perhaps inadequately answered all those years ago: How much do biological ties really matter?

In a recent newsletter, the journalist Alison Motluk, who covers assisted reproduction, highlighted a discussion comparing three scenarios in which people were cut off from a biological parent:

One had a biological parent die before they were born. A second had a biological parent abscond before they were born. A third was conceived using an anonymous donor. Why do we acknowledge loss and feel empathy in the first two scenarios but not in the third?

I liked the way the question was framed, in terms of empathy rather than the harder-edged language of rights. Because when donor-conceived people ask for regulations on the exchange of sperm, they are also asking for acknowledgment that this biological exchange matters, that biological origins matter. We naturally recognize this in situations where a child has never met a parent owing to tragic life circumstancesso how does the situation then differ when the bond is severed by biotechnology instead? In my conversations with donor-conceived people, they often grappled with comparisons to more familiar scenarios. They are asking for rights, but they are also asking for compassion.

Tiffany Gardner, now 39 and an attorney in Atlanta, told me she had lost her father, Ken, to colon cancer when she was 4. Although Gardner later became close to her stepfather, she continued to treasure the few things she knew about Kenhe had been good at baseball and horseback riding, and she gravitated toward the same sports to maintain some kind of connection. At age 35, Gardner learned that her parents had actually used a sperm donor, and when she eventually found him, via a DNA test, parts of her identity suddenly clicked into place. She saw a photo of the donors son and it was, she told me, my face popping up as a dude. Her biological father had been an art teacher, and Gardner immediately linked that detail to her own longing to go to art school when she was younger. These connections made it all the more painful when the donors family objected to his having a relationship with her, and he abruptly cut her off.

To Gardner, her desire to connect with her biological fatherher actual biological father, this timewas not so different from her desire to stay connected with Ken. Her immediate family has been supportive, she said, but shes faced some pushback from acquaintances and older family members. Ive had a couple people that are sort of like, I dont get it. Those people arent really your family. Why do you want anything to do with this? she told me. But to Gardner, genetic ties clearly matteredif not, why did she spend her first 35 years trying to connect with a dead father she never really knew?

Adams began asking these same questions when he became a father. Not long after his daughters birth, it occurred to him that if he died right there and then, people would acknowledge the tragedy of his daughter never getting to know him. They would all recognize I was her father, he told me. Or, he went on, lets say, for example, a one-night stand. People recognize that as a tragedy, when that person is not in that childs life. Or in adoption, we recognize that as being problematic. The adoption world has in fact moved toward more and more open adoptions.

Isnt the difference, I asked, that sperm donation never promises, even implicitly, a relationship, and in fact in most cases explicitly disavows one before conception? To Adams, that disavowal made the situation even worsethat society would intentionally create people cut off from their biological parents. The genetic connection was, to him, immutable. If the connection really meant nothing, Adams said, why do many couples who use an egg or sperm donor still choose to have the child be related to one parent? It cant be that the connection is meaningful in one case but not in the other.

Not every donor-sperm-conceived personthey are, after all, a large groupfeels the same about the strength of genetic connection. In a 2020 survey conducted by We Are Donor Conceived in its own Facebook group and another called the Worldwide Donor Conceived People Network, 67 percent of respondents wanted the donors identity to be known from birth. Only 33 percent, though, felt that donors needed to be available for a relationship with the child from birth.

But its also impossible to survey the donor-conceived people who never join these groups, for whom this fact about their birth might feel unremarkable. Anecdotally, at least, this is common. Many of the donor-conceived people Ive talked with mentioned half siblings who never responded to messages through 23andMe or AncestryDNA, or who responded politely once and stopped there. Some people might feel very little curiosity about their biological origins, says Brianne Kirkpatrick, a genetic counselor who has helped many people through DNA discoveries. Some might feel that any curiosity would be betraying their family, and some are simply more interested in donor siblings than the donor. Age or stage of life may play into how people react differently, Kirkpatrick suggests, but theres not much research on why. What donor-conceived people want is a question few people asked until recently.

Sperm donation has already changed dramatically in the past three to four decades, and some of the changes that donor-conceived people are pushing have indeed happened, even if they are not necessarily enshrined in law. The secrecy around the use of donor sperm, for example, has dissipated as more single women and lesbian couples have openly used sperm banks. The ethics committee of the American Society of Reproductive Medicine (ASRM) now strongly encourages parents to tell their children if they were donor-conceived. Fertility doctors have also gone from procuring live sperm samples themselvescommonly from medical studentsto ordering frozen sperm from banks that can more thoroughly, if not always perfectly, screen donors. ASRM guidelines suggest that banks voluntarily limit the number of births per donor to 25 in a given population of 800,000 people. And sperm banks are more likely to offer open-ID donations, in which the donor can be contacted by his biological children. Some banks still have anonymous donations, in which they dont share any donor information. But these days, I think someone would have to be intentionally ignorant to not realize anonymity is not possible, Kirkpatrick says. Even without more formal regulation of sperm donation, widespread DNA testing means theres no more hiding in the passage of time.

These shifts have left plenty of gaps, though: Sperm banks, for example, do not have to keep track of births or coordinate with one another, so one donor could still be a prolific biological father. (There are donors with more than 100 biological children.) And in practice, anonymous donation still leaves the job of identifying a biological parent to the donor-conceived person. This could be easy enough if they are lucky and get a close DNA match such as a half sibling or first cousin, but it may be impossible or near-impossible if not. Some donor-conceived people have spent years searching.

Even so, the changing landscape of sperm donation is impossible to ignore, and donor-conceived children have grown up into adults who have their own opinions. At the ASRMs annual meeting in Baltimore next week, a panel is scheduled to discuss Open Identity Gamete Donation: What Are the Children Saying? (Gamete is the scientific term for egg or sperm.) But Erin Jackson, the founder of We Are Donor Conceived, pointed out to me that, despite the panels name, it features four experts and the mother of a donor-conceived sonbut not any children who are donor-conceived. To her, this just revealed how the fertility industry continues to ignore the people it helped create.

When I inquired with the ASRM, the organizations chief advocacy and policy officer, Sean Tipton, underplayed the importance of a single panel. So does ASRM have any plans to engage with the donor-conceived community? I asked. We very well might, Tipton said, without specifying what that would entail. He also questioned whether they were in fact the right people to engage: Were including patients a lot more in our organizations deliberations but, again, these are not patients. Furthermore, he added, a 30-year-old, donor-conceived person in 2021is that the right person to consult about somebody whos going through the process now? After all, none of us has a say in the circumstances of our conception, natural or otherwise. If donor-conceived people have the right to know about their genetic parentage, we should also consider how that right extends to other aspects of parent-child relationships and in other situations, says Judith Daar, the dean of Northern Kentucky Universitys law school and the former chair of the ASRM ethics committee that drafted guidelines for disclosure about donor conception in 2018. For example, she says, theres a debate in the infertility community whether a child had a right to know they were conceived through IVF, which may reveal aspects of the parents private reproductive history. And what about naturally conceived children, Daar askswhat do parents owe them about their sex lives?

Most people dont want to know how they were conceived, you know? Jackson said. Its not something you want to picture. For her, its medical, though. And, more important when donors and sperm banks are involved, its commercial. Money changes hands. Contracts are signed. The feeling of commodification is very real, she told me. The fertility industry is responsible for the creation of human beings; it is also a multibillion-dollar industry that is growing every year. Donors, doctors, and parents today, Jackson said, should be thinking more clearly about the futurebeyond holding a baby in their arms to what that baby will want when they grow up. She sees inspiration in the campaigns to abolish donor anonymity in the U.K. and parts of Australia, and she hopes to turn We Are Donor Conceived into a nonprofit, so that it might more forcefully advocate for changes.

Adams, in Australia, did eventually find his biological father, after multiple DNA tests and investigative work spanning years. (Though he got a donor number from medical records, the number didnt match anyone.) They look like spitting images of each other. Anybody whos seen the photos of the two of us can spot it instantaneously, he said. Theyve met in person and speak frequently on the phone. He finally found the connection he had been searching for, and now he wants others to find it too.

Can you mix COVID vaccines? What that could mean for Moderna and J&J boosters – CNET

Posted: October 16, 2021 at 2:04 am

Jasmin Merdan/Getty Images For the most up-to-date news and information about the coronavirus pandemic, visit the WHO and CDC websites.

In a flurry of booster demand and unanswered questions in the US, an advisory committee to the US Food and Drug Administration is meeting today and tomorrow to discuss whether to authorize booster doses of Moderna and Johnson & Johnson's COVID-19 vaccines, which may also include discussion on whether to recommend people get a different COVID-19 vaccine for boosters or future doses. In other words, it's possible health officials may recommend some people start "mixing and matching" coronavirus shots.

In September, the Centers for Disease Control and Prevention recommended Pfizer COVID-19 boosters for all people who originally got vaccinated with the Pfizer vaccine and are aged 65 and older, individuals living in long-term care facilities and adults ages 50 to 64 who have underlying medical conditions. Younger adults ages 18 to 49 who have underlying medical conditions, such as diabetes and obesity, and adults whose jobs put them at higher risk of COVID-19 may also choose to get a booster. Of this large group, you're only eligible for a booster if you already received two Pfizer shots.

Understandably, this left people who have similar health conditions or those who are also at risk of COVID-19 infection because of their work -- but happened to get Moderna or Johnson & Johnson -- largely in the dark. If Pfizer is the only authorized booster so far, what does this mean for people who didn't originally get Pfizer?

Preliminary data from a study that looked at booster doses in people who originally received either Pfizer, Moderna or Johnson & Johnson was published online yesterday, but it needs to be reviewed, along with other data, before health officials make a recommendation for mixing vaccine series.

"Of course, as with all things we do, they must be submitted to the FDA for their regulatory approval," chief medical adviser Dr. Anthony Fauci said about booster data during a White House COVID-19 briefing in September. "You don't want to get ahead of the FDA, but at least that's where the data are right now."

Mixing COVID-19 vaccines is being done in other countries, and it's been done in the US with other vaccines (it's also being done unofficially in medical offices as some people seek out COVID-19 boosters for themselves.) But before they make an official recommendation or give any sort of green light, health officials in the US need to determine whether the benefits of mixing different vaccine types outweigh the potential risks if any, as well as consider the differences between the vaccines.

Our Health & Wellness newsletter puts the best products, updates and advice in your inbox.

For starters, while all three vaccines have the same effect (though they vary slightly in their efficacy), the way they function is a little different. Pfizer and Moderna are mRNA vaccines, which teach our cells to make a specific protein and build immunity against a virus. Johnson & Johnson is a viral vector vaccine, which uses a harmless virus to activate an immune response and tell our bodies what to fight in future infections. Both vaccine types prepare our immune systems for COVID-19 infection, and none of the coronavirus vaccines infects us with the actual coronavirus.

Whether you're eligible for a booster now, want to be prepared for a potential third shot in the future, or are making plans to get your first COVID-19 shot, here's what we know now about mixing different vaccine brands.

The newest CDC recommendation for some adults who received Pfizer only applies to those who got Pfizer for their initial coronavirus vaccine series. So if you qualify, you'll get another shot of Pfizer at least six months after your second dose.

If you're "moderately or severely immunocompromised," according to the Centers for Disease Control and Prevention, and received Pfizer or Moderna as your COVID-19 vaccine, it's recommended that you receive another dose at least four weeks after your second shot. Examples of people who qualify right now include organ transplant patients, people who are being treated for tumors or cancer in the blood, people who've received a stem cell transplant, folks with untreated or advanced HIV infection and people with other conditions or who are taking medications that suppress their immune system. If you're unsure whether you need one, talk with your doctor.

If you got Pfizer for your initial vaccine, you should get a third dose of Pfizer, and the same goes for Moderna. However, the CDC says that if you don't know what brand you received or if that brand isn't available to you, you could get the other mRNA vaccine. (Johnson & Johnson recipients who are immunocompromised aren't included in this recommendation by the CDC.)

So right now, the only CDC-endorsed "mix and match" approach is for immunocompromised people who received Moderna or Pfizer and can't receive the same mRNA vaccine for whatever reason (you lost your vaccine card and can't remember, the first one isn't available in your area, etc.) This does not apply to people who are eligible for Pfizer's booster for whatever reason.

Generally, the CDC says that because data on people who've received two different vaccines (called a "mixed series") is limited, it's preferable to get your second dose of the same vaccine, even if it means waiting longer than the recommended time. But if there was a mix-up at the clinic oryou accidentally received Pfizer for the second dose when your first shot was Moderna, you don't need a third dose of either vaccine and you're still considered fully vaccinated two weeks after your second dose of an mRNA vaccine, according to the CDC.

If you got Pfizer or Moderna for the first shot, then Johnson & Johnson for the second dose because you have a contraindication (an allergic reaction to your first dose or another medical reason you shouldn't get another dose of your first shot), you're considered fully vaccinated two weeks after your Johnson & Johnson shot, per the CDC.

The fact that the current guidance allows people currently eligible for an extra COVID-19 shot to get a dose of Pfizer if Moderna isn't available, and vice versa, is likely because scientists determined that the benefits of a third dose of coronavirus vaccine (protection against severe disease) for some people outweigh the unknown risks that may come from receiving another kind of shot.

But before scientists and public health officials can go on record recommending a mixed-series vaccine for the general population, they need to determine that it's a safe practice and that the benefits of it outweigh potential risks.

"There are theoretical advantages to receiving different vaccine types, in that different parts of the immune system can be impacted for protection," says Dr. Margaret Day, physician and vaccine co-chair at University of Missouri Health Care. "But medical research is ongoing about antibody responses and T cell responses as well as safety and efficacy in trials."

Information from outside the US shows promising efficacy, though, and other countries have been allowing people to receive two different vaccines, including Germany, Canada, Sweden, France, Spain and Italy, per The New York Times. (In some cases, mixing vaccine types comes down to what's available.) In a study published in the journal Nature, researchers in Spain found that people who received one dose of AstraZeneca (a similar vaccine to Johnson & Johnson) and then received a dose of Pfizer seem to produce a higher antibody response than people who receive two doses of AstraZeneca. It isn't clear whether this group had a higher immune response than people who received two doses of Pfizer.

In the US, the National Institutes of Health and the National Institute of Allergies and Infectious Diseases announced a study in June that tested mixing different COVID-19 vaccines. Data from that mix-and-match trial with Moderna as the booster vaccine has been shared with the CDC's Advisory Committee on Immunization Practices and the Food and Drug Administration, a spokesperson with the NIAID said. The FDA committee is expected to discuss that data on Friday.

When or if public health officials determine that a mixed vaccine regimen or "heterologous priming" is safe and effective, that may open doors for people if they become eligible for additional doses. It may also prompt public health officials to make certain vaccine recommendations for specific groups. In the United Kingdom, for example, the National Health Service says that for people under age 40 who don't have a health condition, it's "preferable for you to have the Pfizer/BioNTech or Moderna vaccine instead of Oxford/AstraZeneca," because of AstraZeneca's link to a very rare but serious blood-clotting disorder in younger people (who have a lower risk of dying from COVID-19 without the influence of another health condition). Germany issued a similar recommendation about mixing AstraZeneca with an mRNA vaccine.

Johnson & Johnson's shot in the US has also been linked to the same rare-but-serious blood-clotting disorder, and the CDC says, "Women younger than 50 years old especially should be aware of the rare but increased risk of this adverse event, and they should know about other available COVID-19 vaccine options for which this risk has not been seen." Should a booster or additional dose ever be needed for this group, and available data shows that a mixed series is safe, it might be safe to assume that the CDC could suggest that people in this group get a different vaccine the second time around.

In San Francisco, some Johnson & Johnson recipients have gone ahead and received an mRNA shot after the city made an "accommodation" for those asking for one, though it hasn't changed health policy in San Francisco.

The vaccine for Ebola, made by Johnson & Johnson, uses a mixed-dose approach. According to the EU Research and Innovation Magazine, the two-part vaccine is made up of two slightly different technologies and was developed this way because of the immune response it could produce.

Dr. Margaret Day says that while sometimes different vaccine brands are used, "a major difference is having years' worth of data available for review for those."

While research for everything else is underway, Day says the best thing you can do is to complete the COVID-19 vaccine series as currently reviewed.

"Ultimately, the absolutely most important action people can take today to protect themselves and their communities against COVID-19 is getting their initial COVID-19 vaccine series," Day says. "We will be faced with questions about the best strategies for initial series vaccination and additional vaccinations and booster doses, and those answers will become available in time."

In the US, 78.5% of adults have received at least one COVID-19 shot, according to CDC data. According to Our World in Data, 48% of the world's population has received at least one dose of a coronavirus vaccine. Only 2.5% of people in lower-income countries have received a COVID-19 vaccine.

Antibody treatment for MIS-C works by depleting inflammatory immune cells – National Institutes of Health

Posted: October 16, 2021 at 2:03 am

News Release

Friday, October 15, 2021

Intravenous immune globulin (IVIG) a common treatment for multisystem inflammatory syndrome in children (MIS-C) likely works by depleting immune cells called neutrophils, according to a recent study funded by the National Institutes of Health (NIH). MIS-C is a rare condition that usually affects school-age children who initially had only mild COVID-19 symptoms or no symptoms at all. The researchers also found that IVIG works in a similar manner for treating Kawasaki disease, another rare inflammatory condition that affects children and shares symptoms with MIS-C. The findings are published in the Journal of Clinical Investigation.

MIS-C is marked by severe inflammation of two or more parts of the body, including the heart, lungs, kidneys, brain, skin, eyes and gastrointestinal organs. Its symptoms overlap with Kawasaki disease, and treatments for MIS-C are guided in part by what is known about treating Kawasaki disease. IVIG, which is made up of antibodies purified from blood products, is a common and effective treatment for heart complications caused by Kawasaki disease. For MIS-C patients, however, IVIG alone does not always resolve symptoms, and healthcare providers may need to prescribe additional anti-inflammatory drugs.

To better understand how IVIG works and to improve treatments for children with MIS-C, researchers led by Ben A. Croker, Ph.D., and Jane C. Burns, M.D., from the University of California San Diego School of Medicine, profiled immune cells from patients with MIS-C or Kawasaki disease. The team sampled cells before treatment began as well as 2 to 6 weeks after patients received IVIG. The researchers found that neutrophils from these patients were highly activated and a major source of interleukin 1 beta (IL-1), which is one driver of inflammation in the body. After IVIG treatment, these activated neutrophils were significantly depleted in patients with MIS-C or Kawasaki disease.

According to the study authors, their findings are the first to explain why IVIG is effective for both conditions. However, more work is needed to understand how IVIG causes cell death in these activated neutrophils and why certain patients with MIS-C require additional anti-inflammatory treatments. Overall, the research will help healthcare providers as they determine the most effective methods to treat patients with MIS-C.

The study is funded by NIHs Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the National Heart, Lung, and Blood Institute (NHLBI), and the National Institute of General Medical Sciences (NIGMS). The work is supported by NIHs CARING for Children with COVID, PreVAIL kIds and RADxSM-rad research programs.

Dr. Kahl on the Potential Utility of Frontline CAR T-Cell Therapy in MCL – OncLive

Posted: October 16, 2021 at 2:03 am

Brad S. Kahl, MD, discusses the potential utility of frontline CAR T-cell therapy in mantle cell lymphoma.

Brad S. Kahl, MD, professor of medicine, Department of Medicine, Oncology Division, Medical Oncology, Washington University School of Medicine in St. Louis, discusses the potential utility of frontline CAR T-cell therapy in mantle cell lymphoma (MCL).

CAR T-cell therapy has the potential to move into earlier lines of treatment, including the frontline setting, in MCL; however, longer follow-up is needed with CAR T-cell therapy in the relapsed/refractory setting before frontline clinical trials can be explored, Kahl says. Currently, CAR T-cell therapy is demonstrating high response rates at 12 and 18 months of follow-up in the relapsed/refractory setting, but it is unknown whether these responses will remain durable at 3 or 5 years.

Positive 3-year data in the relapsed/refractory setting could provide the clinical rationale to evaluate CAR T-cell therapy in the frontline setting, Kahl says. Pending these results, CAR T-cell therapy could replace autologous stem cell transplant as consolidative therapy or offer a standard option for patients with high-risk biologic features, such as TP53 mutations, Kahl concludes.

Generation Bio to Present at European Society of Gene and Cell Therapy 2021 Annual Virtual Congress – Yahoo Finance

Posted: October 16, 2021 at 2:03 am

CAMBRIDGE, Mass., Oct. 15, 2021 (GLOBE NEWSWIRE) -- Generation Bio Co. (Nasdaq: GBIO), a biotechnology company innovating genetic medicines for people living with rare and prevalent diseases, today announced an oral presentation at the European Society of Gene and Cell Therapy (ESGCT) Annual Virtual Congress taking place October 19-22. The presentation will highlight preclinical advances from the companys retina therapeutic area.

We are excited to share our preclinical data demonstrating broad access to key cell types with our lipid nanoparticle developed for the retina, said Matthew Stanton, Ph.D., chief scientific officer of Generation Bio. Many inherited retinal diseases remain out of reach for viral-based gene therapies due to limited cargo capacity. We believe our non-viral delivery technology could overcome this barrier and expand the potential of our genetic medicine platform to treat more diseases.

The presentation will be streamed online for registered attendees on October 22, and a recording of the presentation will be made available for attendees for 30 days following the event.

Generation Bio will present:

About Generation BioGeneration Bio is innovating genetic medicines to provide durable, redosable treatments for people living with rare and prevalent diseases. The companys non-viral genetic medicine platform incorporates a novel DNA construct called closed-ended DNA, or ceDNA; a unique cell-targeted lipid nanoparticle delivery system, or ctLNP; and a highly scalable capsid-free manufacturing process that uses proprietary cell-free rapid enzymatic synthesis, or RES, to produce ceDNA. The platform is designed to enable multi-year durability from a single dose, to deliver large genetic payloads, including multiple genes, to specific tissues, and to allow titration and redosing to adjust or extend expression levels in each patient. RES has the potential to expand Generation Bios manufacturing scale to hundreds of millions of doses to support its mission to extend the reach of genetic medicine to more people, living with more diseases, around the world.

Dr. Erba on the Evolution of Treatment in MCL – OncLive

Posted: October 16, 2021 at 2:03 am

Harry Paul Erba, MD, PhD, discusses the evolution of treatment in mantle cell lymphoma.

Harry Paul Erba, MD, PhD, instructor, clinical investigator, Division of Hematologic Malignancies and Cellular Therapy, Department of Medicine, Duke University School of Medicine, member, Duke Cancer Institute, director, Leukemia Program and Phase I Development in Hematologic Malignancies, Duke Health, discusses the evolution of treatment in mantle cell lymphoma (MCL).

Similar to acute myeloid leukemia, the goal of therapy in MCL should be the key focus from treatment initiation. For example, a younger patient with limited comorbidities should be considered for curative-intent therapy or treatment with a time-limited regimen to elicit deep responses and prolonged progression-free survival, Erba says.

High-dose cytarabine-based therapies, such as the Nordic regimen known as maxi-CHOP, and autologous stem cell transplant could be considered for patients with MCL, Erba explains. Oral therapies, including BTK inhibitors, are also available options for patients with relapsed/refractory MCL or older patients who cannot tolerate intensive chemotherapy, Erba concludes.

Modern Treatment Standards Require State-of-the-Art Molecular Profiling – Cancer Network

Posted: October 16, 2021 at 2:03 am

In my mind, the question is not who should get chemotherapy, but who can avoid chemotherapy in this day and age.

As more and more targeted therapy options emerge in the cancer space, investigators continue to see positive impacts on long-term outcomes. However, this wider, advanced, individualized range of treatment options that may be offered to patients requires more sophisticated molecular testing techniques.

In an interview with ONCOLOGY, Charu Aggarwal, MD, MPH, discussed this topic as it relates to her ongoing research, as well as how it may carry to other areas of oncology care outside of her area of expertise in the lung cancer space. She is the Leslye M. Heisler Associate Professor for Lung Cancer Excellence in the Department of Medicine at the University of Pennsylvanias Perelman School of Medicine in Philadelphia as well as co-chair for the 6th Annual International Congress on Immunotherapies in Cancer, hosted by Physicians Education Resource, LLC (PER).

Aggarwal spoke about how liquid biopsies, rather than invasive procedures, can help determine treatment prognosis. She also detailed how immunotherapy has evolved as a mainstay of treatment and how clinicians are now looking at adverse effects (AEs) as a positive sign of treatment efficacy.

A: Molecular genotyping is becoming extremely important in nonsmall cell lung cancer. At least 9 biomarkers1 must now be tested at initial diagnosis, and the gold standard for testing has been to use tissue-based testing. [However], its often a problem to get tissue because these biopsies are small and sometimes not enough tissue or not enough DNA [is present] on these samples. [So then] we asked, Could we complement our ability to test for these mutations using tissue alone by adding in plasma-based sequencing? We conducted a follow-up trial with about 300 patients here [at the University of Pennsylvania] and found that by adding plasma-based approaches, using 2 tubes of blood, we could get [results] relatively easier compared with tissue-based sequencing.2 We were able to increase our detection of molecular alterations from about 20% to about 36%a significant increase. This means that more patients were able to get targeted therapy, receive a drug based on their molecular profile, and have significant benefit. Patients were able to avoid chemotherapy or immunotherapy.

We are currently doing much more with liquid biopsies [and are] really looking at the dynamics of circulating tumor DNA [ctDNA], to guide whether patients are responding to treatment. If the ctDNA goes down, that gives us a sense, an indicator, that the therapy is working, [possibly] before we get a radiographic response, before I even get the CT scan. [Liquid biopsy] is an active area of research that I think will be extremely interesting.

A: Exactly. Thats the point: We can [check progress] in a minimally invasive way.

A: Lung cancer is among the leading cancer subtypes where liquid biopsies are being used. Thats because a significant amount of ctDNA is shed into the bloodstream in patients with advanced disease. [Also], lung cancer has so many different [molecular, actionable] subtypes that now have targetable drugs. We can say [to a patient], You have an EGFR mutation or You have a MET exon 14 [skipping] mutationIm going to give you a pill. There is more actionability in lung cancer than in other diseases. However, breast cancer, gastrointestinal cancer, and genitourinary cancer are all now [using] liquid biopsies and expanding the space to utilize it in the clinical setting.

A: I think we are getting there. Were not completely there, because we still need a few things from tissue samples. We can never characterize the cell type or the architecture of a tumor, which are still very necessary, with a liquid biopsy. Looking at tissue is still extremely important, no matter what. I think plasma or liquid biopsies will be essential to give us information about the rest of the tumor. In fact, it sometimes gives us a clearer picture of the heterogeneous nature of the tumor, so we can get a sense of the cells that may have more metastatic potential and may have a slightly different mutational profile. We can gather that [information] much better than we can with a single small biopsy.

A: The most obvious indication that [a treatment is working is] less tumor. However, were also looking at other things like methylation signatures, RNA sequencing, and changes in mutational profile over time that may help us eventually [determine how treatment is going].

A: We have learned a great deal about when to use targeted therapy in lung cancer. We need to know a patients molecular subtype. One way we [learn] that is by using both tissue and plasma sequencing, which is a must. Once we know the molecular subtype, the next question is how we utilize the information to guide therapy. In my mind, the question is not who should get chemotherapy, but who can avoid chemotherapy in this day and age. I feel that with the explosion of immunotherapy, we can now deliver immunotherapy safely with a survival benefit for most of our patients. There will always be a subset who dont get immunotherapy, but the vast majority of our patients can, and we use PD-L1 testing to determine which patients can get immunotherapy alone. Again, thats only for a small subset of patients; for [the rest, were still] using a combination of chemotherapy and immunotherapy.

A: The premise of immunotherapy is reactivating the immune system and harnessing the power of T cells during cancer treatment. We know that our T cells as well as our bodies are inherently programmed to fight cancer. However, cancer cells may express inhibitory molecules; these can then be inhibited using PD-L1 inhibitors, potentially creating the immune response again. Thats the premise: the immune activation thats inherent in the immune system to fight cancer.

A: Many guidelines now help us with managing irAEs in a stepwise fashion, including guidelines from the National Comprehensive Cancer Network, the Society for Immunotherapy of Cancer, and the American Society of Clinical Oncology. Id [like to] add that recent evidence suggests that the presence of irAEs in patients who receive immunotherapy may be related to better outcomes, depending on the grade of AEs. Preliminary data, at least, suggest that grade 2 and 3 AEs may be better in terms of predicting for an improved outcome to immunotherapy, which I think is very interesting. Its reminiscent of the old days when we used to look at things like rash from EGFR inhibitors [to] tell us that the drug is working, [and] also that they are more likely to see a response.

FDA Approves Genentech’s Tecentriq as Adjuvant Treatment for Certain People With Early Non-Small Cell Lung Cancer – Business Wire

Posted: October 16, 2021 at 2:03 am

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the U.S. Food and Drug Administration (FDA) has approved Tecentriq (atezolizumab) as adjuvant treatment following surgery and platinum-based chemotherapy for adults with Stage II-IIIA non-small cell lung cancer (NSCLC) whose tumors express PD-L11%, as determined by an FDA-approved test.

Tecentriq is now the first and only cancer immunotherapy available for adjuvant treatment of NSCLC, introducing a new era where people diagnosed with early lung cancer may have the opportunity to receive immunotherapy to increase their chances for cure, said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. Todays landmark approval gives physicians and patients a new way to treat early lung cancer that has the potential to significantly reduce risk of cancer recurrence, after more than a decade with limited treatment advances in this setting.

Too many patients with early-stage lung cancer experience disease recurrence following surgery. Now, the availability of immunotherapy following surgery and chemotherapy offers many patients new hope and a powerful new tool to reduce their risk of cancer relapse, said Bonnie Addario, Co-founder and Chair, GO2 Foundation for Lung Cancer. With this approval, it is more important than ever to screen for lung cancer early and test for PD-L1 at diagnosis to help bring this advance to the people who can benefit.

The approval is based on results from an interim analysis of the Phase III IMpower010 study that showed treatment with Tecentriq following surgery and platinum-based chemotherapy reduced the risk of disease recurrence or death by 34% (hazard ratio [HR]=0.66, 95% CI: 0.50-0.88) in people with Stage II-IIIA (UICC/AJCC 7th edition) NSCLC whose tumors express PD-L11%, compared with best supportive care (BSC). Safety data for Tecentriq were consistent with its known safety profile and no new safety signals were identified. Fatal and serious adverse reactions occurred in 1.8% and 18%, respectively, of patients receiving Tecentriq. The most frequent serious adverse reactions (>1%) were pneumonia (1.8%), pneumonitis (1.6%), and pyrexia (1.2%).

The review of this application was conducted under the FDAs Project Orbis initiative, which provides a framework for concurrent submission and review of oncology medicines among international partners. According to the FDA, collaboration among international regulators may allow patients with cancer to receive earlier access to products in other countries where there may be significant delays in regulatory submissions. Simultaneous applications were submitted to regulators in the United States, Switzerland, the United Kingdom, Canada, Brazil and Australia under Project Orbis. Additionally, the FDA reviewed and approved the supplemental application under its Real-Time Oncology Review pilot program, which aims to explore a more efficient review process to ensure safe and effective treatments are available to patients as early as possible.

Tecentriq has previously shown clinically meaningful benefit in various types of lung cancer, with six currently approved indications in the U.S. In addition to becoming the first approved cancer immunotherapy for adjuvant NSCLC, Tecentriq was also the first approved cancer immunotherapy for front-line treatment of adults with extensive-stage small cell lung cancer (SCLC) in combination with carboplatin and etoposide (chemotherapy). Tecentriq also has four approved indications in advanced NSCLC as either a single agent or in combination with targeted therapies and/or chemotherapies. Tecentriq is available in three dosing options, providing the flexibility to choose administration every two, three or four weeks.

Genentech has an extensive development program for Tecentriq, including multiple ongoing and planned Phase III studies across different lung, genitourinary, skin, breast, gastrointestinal, gynecological, and head and neck cancers. This includes studies evaluating Tecentriq both alone and in combination with other medicines, as well as studies in metastatic, adjuvant and neoadjuvant settings across various tumor types.

About the IMpower010 study

IMpower010 is a Phase III, global, multicenter, open-label, randomized study evaluating the efficacy and safety of Tecentriq compared with BSC, in participants with Stage IB-IIIA NSCLC (UICC/AJCC 7th edition), following surgical resection and up to 4 cycles of adjuvant cisplatin-based chemotherapy. The study randomized 1,005 people with a ratio of 1:1 to receive either Tecentriq for 1 year (16 cycles), unless disease recurrence or unacceptable toxicity occurred, or BSC. The primary endpoint is investigator-determined DFS in the PD-L1-positive Stage II-IIIA, all randomized Stage II-IIIA and intent-to-treat (ITT) Stage IB-IIIA populations. Key secondary endpoints include overall survival (OS) in the overall study population, ITT Stage IB-IIIA NSCLC.

About lung cancer

According to the American Cancer Society, it is estimated that more than 235,000 Americans will be diagnosed with lung cancer in 2021. NSCLC accounts for 80-85% of all lung cancers and approximately 50% of patients diagnosed with NSCLC are diagnosed with early-stage (Stages I and II) or locally advanced (Stage III) disease. Today, about half of all people with early lung cancer still experience a cancer recurrence following surgery. Treating lung cancer early, before it has spread, may help prevent the disease from returning and provide people with the best opportunity for a cure.

About Tecentriq (atezolizumab)

Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

Tecentriq U.S. Indications

Tecentriq is a prescription medicine used to treat adults with:

A type of lung cancer called non-small cell lung cancer (NSCLC).

A type of lung cancer called small cell lung cancer (SCLC).

It is not known if Tecentriq is safe and effective in children.

Important Safety Information

What is the most important information about Tecentriq?

Tecentriq can cause the immune system to attack normal organs and tissues in any area of the body and can affect the way they work. These problems can sometimes become severe or life threatening and can lead to death. Patients can have more than one of these problems at the same time. These problems may happen anytime during their treatment or even after their treatment has ended.

Patients should call or see their healthcare provider right away if they develop any new or worse signs or symptoms, including:

Lung problems
