MaxCyte Advances Phase I Clinical Trial of Lead CARMA(TM) mRNA-based Cell Therapy to Third Cohort of Patients – Herald-Mail Media

Posted: October 24, 2019 at 11:47 pm

GAITHERSBURG, Md., Oct. 24, 2019 /PRNewswire/ --MaxCyte, the global cell-based therapies and life sciences company, announces today that, having completed dosing of the second cohort of patients, clinical investigators have initiated dosing in the third cohort of patients of MaxCyte's Phase I clinical trial with the next higher cell dose of MCY-M11. This lead, wholly-owned, non-viral mRNA-based cell therapy candidate from MaxCyte's CARMA platform is a mesothelin-targeting chimeric antigen receptor (CAR) therapy being tested in individuals with relapsed/refractory ovarian cancer and peritoneal mesothelioma.

The dose escalation trial is evaluating the safety and tolerability, as well as preliminary efficacy, of MCY-M11 administered intraperitoneally across a series of ascending dose-level cohorts. In the first two cohorts, the infusion of MCY-M11 has been well tolerated in all patients treated. No dose-limiting toxicities, infusion-related adverse events, on-target or off-target toxicities, or other unwanted events were observed.

"We are making significant progress with our lead CAR therapeutic and our proprietary CARMA autologous cell therapy platform. Furthermore, the on-going trial continues to demonstrate the feasibility of our one-day cell therapy manufacturing process," said Claudio Dansky Ullmann, MD, Chief Medical Officer. "We are very excited about the potential of MCY-M11 as a new, effective therapeutic in solid tumors where the majority of patients still have very limited treatment options."

About the Phase I Clinical TrialThe multi-center, non-randomized, open label, dose-escalation Phase I clinical trial is evaluating the safety and preliminary efficacy of intraperitoneal infusions of MCY-M11 in individuals with platinum-resistant, high-grade, serous adenocarcinoma of the ovary, primary peritoneum or fallopian tube, or individuals with advanced peritoneal mesothelioma with recurrence after prior chemotherapy. MaxCyte anticipates approximately 15 study participants will be enrolled across the two clinical sites participating in the study (the National Cancer Institute (NCI) at the National Institutes of Health (NIH) and Washington University at St. Louis (WUSTL)).

What Did the Winners of the Nobel Prize in Medicine Discover? – JSTOR Daily

Posted: October 24, 2019 at 11:47 pm

Its Nobel Prize season! In the biological sciences, the prestigious prizes are often awarded for discoveries that unlock lifes most basic mechanisms. Nobel-prize-winning work often invokes concepts so fundamental that most people take them for granted. This years Nobel Prize for Physiology and Medicine is no exception. Awarded to William Kaelin Jr, Sir Peter Ratcliffe, and Gregg L. Semenza, the 2019 prize honors the discovery of how cells adapt to the presence of oxygen.

In a 2007 Science article, one of the winners, Gregg Semenza, describes portions of the groundbreaking work. The major issue, as Semenza describes it, is that while many of lifes essential functions depend on oxygen, the amount available is not always consistent. For example, oxygen availability has not been consistent throughout evolutionary history. Early organisms began utilizing oxygen for energy production in increasing degrees, starting around 2.5 billion years ago, about a billion years after life began. After photosynthetic organisms that produced oxygen as a byproduct emerged, the atmospheric oxygen concentration increased dramatically.

Early life, and the cells of more complicated organisms, had to get used to this newly abundant resource. Non-photosynthetic organisms became dependent on oxidative phosphorylation, a means by which the energy of sugar is unlocked for use by cells. Within the cell, in the face of changing external conditions, the amount of available oxygen must be relatively constant. Too little, and it will be impossible to generate energy; too much, and potentially deadly waste products can build up.

Enter HIF-1, aka Hypoxia Induced Factor 1, a protein known as a transcription factor. Transcription factors control the conditions under which a specific gene or genes is expressed, and HIF-1 controls hundreds, perhaps thousands, of genes. The amount of HIF-1 available varies depending on the available oxygen, increasing or decreasing how often the suite of genes controlled by HIF-1 gets expressed.

Semenza and his colleagues teased out the details of the incredibly complicated mechanism by which HIF-1 functions to maintain constant oxygen levels. There are more than a dozen steps, and related biochemical components, in the process. They have found versions of the HIF-1 process in much simpler animals, such as roundworms and flies, helping them trace the evolutionary origins of the adaptation to oxygen.

The work was doubly significant. Not only did the team come to a detailed understanding of one of lifes key processes, the discovery has great potential in medicine as well. Some of the most common cardiovascular diseases, such as stroke or heart attack, restrict the oxygen supply to cells. If a medication or procedure can be devised to control how cells respond to the drop in oxygen, it may be possible to prevent or even reverse the damage from cardiovascular disease. The mechanism may even be manipulated to limit the growth of tumors. Congratulations to doctors Kaelin, Ratcliffe, and Semenza!

Researchers identify genetic variations linked to oxygen drops during sleep – National Institutes of Health

Posted: October 24, 2019 at 11:47 pm

News Release

Thursday, October 24, 2019

Researchers have identified 57 genetic variations ofagenestrongly associated withdeclinesinbloodoxygen levelsduring sleep. Low oxygen levels during sleep are a clinical indicator of the severity of sleep apnea, a disorder that increases the risk of heart disease, dementia, and death. The study, published today in theAmerican Journal of Human Genetics, was funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.

A persons average blood oxygen levels during sleep are hereditary, and relatively easy to measure, said study author Susan Redline, M.D., senior physician in the Division of Sleep and Circadian Disorders at Brigham and Womens Hospital, and professor at Harvard Medical School, Boston. Studying the genetic basis of this trait can help explain why some people are more susceptible to sleep disordered breathing and its related morbidities.

When we sleep, the oxygen level in our blood drops, due to interruptions in breathing. Lung and sleep disorders tend to decrease those levels further, and dangerously so. But the range of those levels during sleep varies widely between individuals and, researchers suspect, is greatly influenced by genetics.

Despite the key roleblood oxygen levelsplayin health outcomes,theinfluenceof genetics on theirvariabilityremains understudied. The current findings contribute toa betterunderstanding, particularly because researcherslookedat overnight measurementsof oxygen levels. Thoseprovide more variability than daytime levelsdue to the stressesassociated withdisordered breathing occurring during sleep.

The researchers analyzed whole genome sequence data from the NHLBIs Trans-Omics for Precision Medicine (TOPMed) program. Tostrengthenthe data,they incorporated results of family-basedlinkage analysis, a method for mapping genes that carry hereditary traits to their location in the genome. Themethod usesdata fromfamilies with several members affected by aparticulardisorder.

This study highlights theadvantage of using family data in searching for rare variants, which is often missed in genome-wide association studies, said James Kiley, Ph.D., director of the Division of Lung Diseases at NHLBI. It showed that, when guided by family linkage data, whole genome sequence analysis can identify rare variants that signal disease risks, even with a small sample. In this case, the initial discovery was done with fewer than 500 samples.

The newly identified 57 variants of the DLC1 gene were clearly associated with the fluctuation in oxygen levels during sleep. In fact, they explained almost 1% ofthevariability in the oxygen levels in European Americans, which is relatively high for complex genetic phenotypes, or traits, that are influenced by myriad variants.

Notably,51 of the 57genetic variantsinfluence and regulate human lung fibroblast cells, a type of cell producing scar tissue in the lungs, according to study author XiaofengZhu, Ph.D., professor at the Case Western Reserve University School of Medicine, Cleveland.

This is important becauseMendelian Randomization analysis, a statistical approach for testing causal relationship between an exposure and an outcome, shows a potential causal relationship between how the DLC1 gene modifies fibroblasts cells andthechanges in oxygen levels during sleep, he said.

Thisrelationship,Kileyadded,suggests thata shared molecular pathway, or a common mechanism,may beinfluencing a persons susceptibility to the lack of oxygen caused by sleep disordered breathingand other lung illnesses such as emphysema.

The project was jointly led by Zhu and Redline, who also directs the National Sleep Research Resource, supported by NHLBI.

No, food companies are not selling products that contain ‘aborted fetus cells’ – PolitiFact

Posted: October 24, 2019 at 11:47 pm

A post shared on Facebook makes a disturbing claim that many popular food and drink companies use "aborted baby fetus cells" to enhance the flavor of their products.

The post features text around a collage of popular food and drink items such as Pepsi, Doritos, Lays, Fritos, Aunt Jemima and Gatorade. It says:

"If only sheeple knew .. that theres a flavor enhancement company called senomyx that puts aborted baby fetus cells in their food and drinks."

The post also has a lengthy caption that appears to be taken entirely from a 2015 blog post by Rich Swier, in which Swier includes this excerpt from a Conservative Post story:

"Kraft, PepsiCo, Nestle, work with Semonyx, a California-based [company] that uses aborted embryonic cells to test fake flavoring chemicals. The aborted human fetal cell line is known as HEK-293, and it is used to see how the human palate will react to synthetic flavors. Since most of todays processed food lacks flavor, companies like Semonyx are hired to develop flavors on their own..."

Swier, according to the blog, holds a doctorate of education from the University of Southern California.

The post was flagged as part of Facebooks efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Facebook.)

Lets just start off by saying that no neither Kraft nor Pepsi nor any other U.S. food company is selling items to the public that contain "aborted baby fetus cells."

The Conservative Post story that Swiers blog and the Facebook post reference no longer exists on the website, but we traced the controversial claim back to a 2011 dispute involving Senomyx, a San Diego-based biotechnology company, and a pro-life group called Children of God for Life.

According to an archived version of a March 29, 2011, press release from Children of God for Life, the group called for a boycott of food companies that contract with Senomyx. The organization pointed to an April 2002 report by Senomyx researchers as proof that the company was adding HEK 293 Human Embryonic Kidney 293 cells in its research and development to enhance flavor.

HEK 293 is a line of cells originally derived from human embryo kidney cells and that were grown in a tissue culture. The first source of the cells was a fetus that was legally aborted in the Netherlands in the 1970s. The cell line has been widely used in biological and medical inquiry, especially for cancer research.

Fetal stem cell research has been used in cell biology for over 30 years. But no company is manufacturing food or other products intended for human consumption that contain aborted human fetuses.

Senomyx has used the HEK 293 cell line in its flavor research to function as the mouths taste receptor cells, allowing the company to test hundreds of substances. But these cells are not in any of the actual food products that consumers would find on the market. CBS News wrote about this in 2011:

"To non-scientists this may sound a bit strange, but the reality is that HEK 293 cells are widely used in pharmaceutical research, helping scientists create vaccines as well as drugs like those for rheumatoid arthritis. The difference here is that Senomyx's work for Pepsi is one of the first times the cells have (potentially) been used to create a food or beverage. (And it's important to note that no part of a human kidney cell are ever a part of Senomyx's taste enhancers or any finished food products.)"

Gwen Rosenberg, vice president of investor relations and corporate communications for Senomyx, described the process to the Miami New Times during the 2011 controversy and said the process is "basically a robotic tasting system":

"(Rosenberg) depicted rows of little plastic square dishes with hundreds of tiny indentations in each dish. A protein is placed in each indentation, then a flavor. If the protein reacts to the flavor, the results are charted. If the new flavor (of which the company has more than 800,000) is successful with the protein test, the company then conducts taste tests with (live) adult humans."

Science and medicine writer Matthew Herper also broke down the process in a 2012 Forbes article:

"This is 35-year-old technology. And it is widely used in cell biology. And there is no way you'll consume them or that the cells would cause any health problems.

"... The kidney cells were forced to take up bits of DNA using a technique invented in 1973 that used a calcium solution. The resulting cells don't act much like human cells at all, but they are very easy to work with and have become workhorses of cellular biology. That's why they're used in the development of drugs and vaccines. (Here's the original paper on the creation of the HEK cells.) No new fetal tissue has been used to keep the cell culture going; the use of this cell line isn't leading to new abortion."

Our ruling

A Facebook post claims several popular food companies add "aborted baby fetus cells in their food and drinks" for flavor enhancement.

The post mischaracterizes the use fetal stem cell research by biotechnology companies such as Senomyx. HEK 293 cells, a cell line from an aborted fetus from the 1970s, has been widely used in cell biology research for over 30 years in multiple areas, including food and pharmaceutical development. But none of these cells are found in the food products available to consumers.

So, while there is a back-story associated with this post, the claim itself is too inaccurate to rate it anything but False.

Vertex Announces Agreement with NHS England for Access to All Licensed Cystic Fibrosis Medicines – Business Wire

Posted: October 24, 2019 at 11:47 pm

LONDON--(BUSINESS WIRE)--Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced an access agreement with NHS England for all currently licensed Vertex cystic fibrosis (CF) medicines and any future indications of these medicines.

This means that within 30 days patients with CF in England ages 2 years and older who have two copies of the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene can be prescribed ORKAMBI (lumacaftor/ivacaftor) by their doctor and CF patients ages 12 years and older who either have two copies of the F508del mutation or one copy of the F508del mutation and a copy of one of the other 14 licensed mutations can be prescribed SYMKEVI (tezacaftor/ivacaftor) in combination with ivacaftor.

The agreement also offers expanded access to KALYDECO (ivacaftor) to include people ages 18 years and older who have the R117H mutation and those patients ages 12 months and older who have one of the nine licensed gating mutations.

Today is a significant day for the cystic fibrosis community in England. This important agreement, reached in collaboration and partnership with NHS England and NICE, will allow more than 5,000 eligible cystic fibrosis patients in England to have access to CFTR modulators to treat the underlying cause of their disease, said Ludovic Fenaux, Senior Vice President, Vertex International.

In addition to England, reimbursement agreements have also recently been announced in Scotland, Australia and Spain.

About CF in the UKOver 10,000 people in the UK have CF the second highest number in the world. Over 8,000 people in England have CF. CF is a debilitating, life-shortening inherited condition that causes progressive damage to organs across the body from birth. Currently, there is no cure for CF and half of people in the UK with CF die before they are 32. The daily impact of treatment is significant. It can take up to four or more hours involving, nebulizers, physiotherapy and up to 70 tablets a day. CF accounts for 9,500 hospital admissions and over 100,000 hospital bed days a year. A third of these are used by children under 15.

About ORKAMBI (lumacaftor/ivacaftor) and the F508del mutationIn people with two copies of the F508del mutation, the CFTR protein is not processed and trafficked normally within the cell, resulting in little-to-no CFTR protein at the cell surface. Patients with two copies of the F508del mutation are easily identified by a simple genetic test.

Lumacaftor/ivacaftor is a combination of lumacaftor, which is designed to increase the amount of mature protein at the cell surface by targeting the processing and trafficking defect of the F508del-CFTR protein, and ivacaftor, which is designed to enhance the function of the CFTR protein once it reaches the cell surface.

For complete product information, please see the Summary of Product Characteristics that can be found on http://www.ema.europa.eu.

About SYMKEVI (tezacaftor/ivacaftor) in combination with ivacaftorSome mutations result in CFTR protein that is not processed or folded normally within the cell, and that generally does not reach the cell surface. Tezacaftor is designed to address the trafficking and processing defect of the CFTR protein to enable it to reach the cell surface and ivacaftor is designed to enhance the function of the CFTR protein once it reaches the cell surface.

SYMKEVI is indicated for people with CF ages 12 and older who either have two copies of the F508del mutation or one copy of the F508del mutation and have one of the following 14 mutations in which the CFTR protein shows residual function: P67L, R117C, L206W, R352Q, A455E, D579G, 711+3AG, S945L, S977F, R1070W, D1152H, 2789+5GA, 3272-26AG, or 3849+10kbCT.

For complete product information, please see the Summary of Product Characteristics that can be found on http://www.ema.europa.eu.

About KALYDECO (ivacaftor)KALYDECO (ivacaftor) is the first medicine to treat the underlying cause of CF in people with specific mutations in the CFTR gene. Known as a CFTR potentiator, ivacaftor is an oral medicine designed to keep CFTR proteins at the cell surface open longer to improve the transport of salt and water across the cell membrane, which helps hydrate and clear mucus from the airways.

KALYDECO is indicated in people ages 12 months and older who have one of the following mutations in the CFTR gene: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N or S549R. KALYDECO is also indicated for the treatment of patients with CF ages 18 years and older who have an R117H mutation in the CFTR gene.

Study links high-salt diet and cognitive impairment – Cornell Chronicle

Posted: October 24, 2019 at 11:47 pm

A high-salt diet may negatively affect cognitive function by causing a deficiency of the compound nitric oxide, which is vital for maintaining vascular health in the brain, according to a new study in mice fromWeill Cornell Medicineresearchers.

When nitric oxide levels are too low, chemical changes to the protein tau occur in the brain, contributing to dementia. In the study,published Oct. 23 in Nature, the investigators sought to understand the series of events that occur between salt consumption and poor cognition and concluded that lowering salt intake and maintaining healthy blood vessels in the brain may stave off dementia.

Accumulation of tau deposits has been implicated in the development of Alzheimers disease in humans.

Our study proposes a new mechanism by which salt mediates cognitive impairment and also provides further evidence of a link between dietary habits and cognitive function, said lead study authorDr. Giuseppe Faraco, an assistant professor of research in neuroscience in the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine.

The new study builds upon research published last year inNature Neuroscienceby Faraco and senior authorDr. Costantino Iadecola, director of theFeil Family Brain and MindResearch Institute and the Anne Parrish Titzell Professor of Neurologyat Weill Cornell Medicine.

The 2018 study found that a high-salt diet caused dementia in mice. The rodents became unable to complete daily living tasks such as building their nests, and had problems passing memory tests. The research team determined that the high-salt diet was causing cells in the small intestine to release the molecule interleukin-17 (IL-17), which promotes inflammation as part of the bodys immune response.

IL-17 then entered the bloodstream and prevented the cells in the walls of blood vessels feeding the brain from producing nitric oxide. This compound works by relaxing and widening the blood vessels, allowing blood to flow. Conversely, a shortage of nitric oxide can restrict blood flow.

Based on these findings, Iadecola, Faraco and their colleagues theorized that salt likely caused dementia in mice because it contributed to restricted blood flow to the brain, essentially starving it. However, as they continued their research, they realized that the restricted blood flow in mice was not severe enough to prevent the brain from functioning properly.

We thought maybe there was something else going on here, Iadecola said.

In their new study, the investigators found that decreased nitric oxide production in blood vessels affects the stability of tau proteins in neurons. Tau provides structure for the scaffolding of neurons. This scaffolding, also called the cytoskeleton, helps to transport materials and nutrients across neurons to support their function and health.

Tau becoming unstable and coming off the cytoskeleton causes trouble, Iadecola said, adding that tau is not supposed to be free in the cell. Once tau detaches from the cytoskeleton, the protein can accumulate in the brain, causing cognitive problems.

The researchers determined that healthy levels of nitric oxide keep tau in check. It puts the brakes on activity caused by a series of enzymes that leads to tau disease pathology, Iadecola said.

To further explore the importance of tau in dementia, the researchers gave mice with a high-salt diet and restricted blood flow to the brain an antibody to promote tau stability. Despite restricted blood flow, researchers observed normal cognition in these mice.

This demonstrated that's whats really causing the dementia was tau and not lack of blood flow, Dr. Iadecola said.

Although research on salt intake and cognition in humans is needed, the current mouse study is a reminder for people to regulate salt consumption, Iadecola said.

And the stuff that is bad for us doesnt come from a salt shaker it comes from processed food and restaurant food, he said. Weve got to keep salt in check. It can alter the blood vessels of the brain and do so in vicious way.

Early Report: Baby Treated With Gene Therapy For Deadly Tay-Sachs Disease Appears To Stabilize – WBUR

Posted: October 24, 2019 at 11:46 pm

It's a very early report, from just two patients, only a few months after treatment. But UMass Medical School Dean Terence Flotte this week shared at a conference what could be landmark news about a terrible genetic disease: Two young patients with Tay-Sachs disease showed no ill effects from a new gene therapy that aims to correct the defect at the heart of the disease.

One of them, treated at just 7 months, has appeared to stabilize instead of following the typical quick slide toward death by age 4.

"It seems right now that she's not degenerating," Flotte said. "But I would say it's too early to say that definitively."

Tay-Sachs is a fatal disorder that tends to affect babies of Eastern-European Jewish ancestry, along with other ethnicities including Cajun and Irish. They usually seem to develop normally for the first few months, but as the disease kills off their nerve cells, they lose the ability to move or breathe on their own.

Flotte says the brain MRI of the baby treated at 7 months looks encouraging, and a clinical trial in more than a dozen patients is expected to begin soon.

Edited highlights of our conversation follow.

You've just presented at a gene therapy conference. What did you report?

We reported the first two patients ever treated with gene therapy for Tay-Sachs disease two infants treated at UMass Memorial Medical Center. What we presented was that these two patients were both treated safely. The vector[the engineered virus that delivered the genetic fix] was administered directly into the brain.

We saw bio-activity, which basically means that we partially restored the enzyme that is missing in Tay-Sachs disease. And the patients were able to tolerate that safely. Also, in one of the cases, with the patient treated early in the course of the disease, we've seen some stabilization of the patient's condition.

What do you mean by stabilization?

One of the patients was treated at 2-1/2 years of age, and that patient had really advanced disease. And we've seen the biochemical effect, but really no clinical effect.

The second patient was treated between 6 and 7 months of age, and in that patient, it appears, although it's still very early, that the patient may be having some continued preservation of her ability to sit up and control her muscles. She's basically seeming to have a more gradual progression at the current time, really being stable at a time point when we might be expecting her to lose some of these developmental milestones.

The best way to explain it is that if a normal infant begins to sit up at around six months of age, Tay-Sachs babies do that, but then they tend to lose the ability to sit up some time between 10 months of age and maybe 15 months of age. The last time we assessed the patient, at 10 months of age (and she's now close to 12 months of age), she seems to not be losing any of the strength required to sit up. We have her older siblings for comparison, and it's encouraging that she seems to be progressing less than they did. We also saw some encouraging signs on her brain MRI.

It seems right now that she's not degenerating. But I would say it's too early to say that definitively. If you think about the progression of development as the slope of a line, the line is flat at this point. It's not going up or going down. The next assessment will be very important, to see whether she's continuing to be flat, which would be a major benefit, or whether she's regressing but just a little bit more slowly.

When you say flat, she's also not advancing as a typical child would?

That is right. It looks like preservation of function rather than gaining. But her oldest sibling died before his third birthday. So considering how fast these patients can decline, a preservation or stabilization could be very important.

It's important to note, too, that we are just at the very beginning. The first patient got the vector injected just into the fluid around the brain, the cerebro-spinal fluid, not into the brain tissue. The second patient got a portion of it injected into the thalamus, which projects out to the entire brain tissue. It's kind of the relay center of the brain, and it can actually ship enzyme out all over the brain.

No one's ever tried that in a humans before, so that was really an important milestone, that intra-thalamic injection. As the trials progress, a larger dose will be injected into the thalamus.

Why has there never been an injection into the thalamus in humans before? What's the challenge?

One challenge is that it is a completely irreplaceable structure. Effectively, all motor and sensory function relays through the thalamus. So if you were to have bleeding or injury to the thalamus, it could cause a stroke or a persistent pain syndrome. So it is somewhat risky. On the other hand, when you're dealing with the infantile form of Tay-Sachs, it's so tragic that it warrants a rather risky approach.

It's been done many times in animals, but this was the first time doing it in patients.

What's next? A full clinical trial?

Yes, Axovant has licensed the program. This first program was done all at UMass Medical School and UMass Memorial Medical Center, and the program is now licensed to Axovant, and they are planning in the near future to do a Phase 2 trial, which we will still be involved in.

It will entail increasing the proportion of the vector injected into the thalamus, so that we will get to the exact proportional dose that was used to correct all of the different animal models that have been treated: a mouse, a sheep and a cat model.

Can Gene Therapy Cure HIV? US Gov’t. Is Banking $100 Million On It. – Livescience.com

Posted: October 24, 2019 at 11:46 pm

The U.S. National Institutes of Health (NIH) wants to cure HIV and sickle cell disease with gene therapies, and will invest $100 million over the next four years towards that goal, the agency announced today (Oct. 23).

For this effort, the NIH will partner with The Bill & Melinda Gates Foundation, which will also invest $100 million.

Critically, the partnership aims to make the therapies affordable and accessible to people around the world, particularly in developing countries, where the burden of these diseases is greatest.

"This is a very bold goal, but we have decided to go big," Dr. Francis Collins, director of the NIH, said in a news conference today.

The effort aims to have the therapies ready for testing in clinical trials in the U.S. and sub-Saharan Africa within the next seven to 10 years.

The majority of the 38 million people with HIV live in developing countries, with two-thirds living in Sub-Saharan Africa. For sickle cell disease, the majority of cases also occur in Sub-Saharan Africa.

The NIH has been trying to find a cure for HIV for "decades and decades," said Dr. Anthony Fauci, director of The National Institute of Allergy and Infectious Diseases. Although current treatments with antiretroviral therapy (ART) are effective at suppressing the virus in the body, they are not a cure, and must be taken everyday. What's more, there are millions of people with HIV who don't have access to ART treatment.

Although scientists are working to develop gene-based cures for HIV, these approaches are often costly and would be difficult to implement on a large scale, Fauci said. For example, some of these therapies take cells out of a patient's body and then re-infuse them, an expensive and time-consuming intervention.

For this reason, the new collaboration will focus on developing cures that use "in vivo" approaches, meaning they happen inside the body, Fauci said. One example of this could be to remove the gene for the CCR5 receptor, which HIV uses to get inside cells. Another idea is to excise the HIV "proviral" DNA that has copied itself into the human genome and lurks in the body even after years of treatment.

Similarly, for sickle cell disease, the goal would be to develop an in vivo therapy that could repair the genetic mutation that causes the disease. This would require a gene-based delivery system that could selectively target the mutation.

"Beating these diseases will take new thinking and long-term commitment. I'm very pleased to see the innovative collaboration announced today, which has a chance to help tackle two of Africa's greatest public health challenges," Matshidiso Rebecca Moeti, the World Health Organization's Regional Director for Africa, said in a statement.

Still, much work would be needed to make sure these therapies are safe and effective.

"It is very clear we have a ways to go, which is why this is a 10 year effort to try and take that promise and turn it into a reality," Collins said.

Earlier this year, the Trump Administration announced a plan to end the HIV epidemic in the U.S. in 10 years.
