Tools developed to probe the virome could aid in variety of research

Researchers at Washington University School of Medicine in St. Louis have received an $8.5 million grant to study the role of gut viruses in inflammatory bowel disease. Tools developed in the course of the project could accelerate research into other roles of the virome in health and disease.

The communities of bacteria that live in our digestive tracts help digest food and produce vitamins, protect against pathogens, and promote the healthy functioning of our immune system. But alongside gut bacteria thrives a vast community of viruses, and we know little about their impact on health and disease.

Efforts to study the gut viral community known as the virome have been hindered by a lack of tools to analyze viral diversity. Researchers at Washington University School of Medicine in St. Louis have received an $8.5 million grant from the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health (NIH) to develop the tools needed to study the role of the virome in inflammatory bowel disease. Once developed, such tools could be applied widely, opening up new avenues of research into the role of the virome in normal physiology and development, as well as diseases such as diabetes, AIDS and cancer.

The virome has been linked to a number of conditions inflammatory bowel disease, malnutrition, graft-versus-host disease and there is also some evidence that the virome supports human health in some ways, said principal investigator David Wang, PhD, a professor of molecular microbiology, and of pathology and immunology. But the problem that plagues virome studies is that people find an association, and then they cant pursue it. Once you find an association, the next step is to see what happens when you introduce the virus to an animal. Does it cause the disease? Make it worse? But there are no tools to carry this out.

Tools to analyze the viral community are relatively scarce partly because viruses are more diverse than bacteria. All bacteria carry certain basic housekeeping genes necessary for life, notably the 16S ribosomal RNA gene. Scientists use this universal gene to screen mixed communities of unidentified bacteria by pulling out all the 16S ribosomal RNA genes and using the sequences to classify the bacteria into families. There is no equivalent universal gene among viruses.

Wang and colleagues previously have discovered differences between the viromes of people with inflammatory bowel disease and healthy people. Inflammatory bowel disease is caused by chronic inflammation in the digestive tract and characterized by persistent diarrhea and abdominal pain. The researchers found that people with the condition carry more Caudovirales, a group of viruses that infects bacteria, and anelloviruses, a family of viruses that infects human cells, in their intestines. But they do not yet know what, if anything, the presence of these viruses means.

The new grant will allow the researchers to follow a group of people with inflammatory bowel disease over time, along with healthy members of their households for comparison. Inflammatory bowel disease tends to be cyclical, flaring up and then resolving again and again. By taking repeated stool samples and analyzing the genetic material of the viruses in such samples, the researchers will be able to see how the makeup of the gut viral community changes over the course of the disease, and gauge whether any particular groups of viruses become more abundant during flare-ups or resolutions. They also will assess what effect treatment has on the virome.

Such analysis will require the development of computational tools to identify the viruses by their genetic sequences, classify them into family groups, identify potential genes within viral sequences, and propose functions of the genes.

With the tools we have now, more than half the sequences cant be classified because they are not similar enough to known sequences, Wang said. We frequently cant even tell whether weve found a virus that infects bacteria or human cells.

Wang and colleagues also will develop ways to cultivate viruses so they can study them. As nonliving things, viruses require a living cell to multiply, which makes cultivation in the lab tricky. To grow viruses that infect human cells, researchers must first culture human cells and then infect them with viruses. But the majority of the viruses in the intestinal tract are likely to infect bacteria, not human cells. Such viruses known as bacteriophages, Latin for bacteria eaters are even more complicated: Researchers must first identify the correct bacterial species from among the thousands in our intestines, culture that species, and then attempt to grow the virus within the bacterial culture.

In previous work, we established the first culture system for a gut virus, Wang said. Were relying on our experience there to try to culture more of these novel viruses. Some of these might actually grow in a quite straightforward way, its just that no one has tried yet. And once we have the viruses, then we can use them to start doing experiments in animal models of inflammatory bowel disease.

The impact of the gut bacterial community on human health is a hot topic of study, with a possible role in health conditions ranging from autoimmunity to heart disease to psychiatric illnesses. The virome may prove to be equally consequential if only we can find a way to investigate it.

This isnt a typical grant, because part of its goal is to build resources that will then be available to the scientific community, Wang said. Creating tools is unsexy and usually unfundable. But we have to build these tools before we can answer the exciting questions.

Along with Wang, the research team includes Michael S. Diamond, MD, PhD, the Herbert S. Gasser Professor of Medicine, and Scott Handley, PhD, an associate professor of pathology and immunology, both at Washington University; Thaddeus Stappenbeck, MD, PhD, of the Cleveland Clinic; and collaborators at Cambridge University in the United Kingdom, San Diego State University in California, and Flinders University in Australia.

For a honey bee, few things are more important than recognizing your nestmates. Being able to tell a nestmate from an invader could mean the difference between a honey-stocked hive and a long, lean winter.

New research from Washington University in St. Louis shows that honey bees rely on chemical cues related to their shared gut microbial communities, instead of genetic relatedness, to identify members of their colony.

Most people only pay attention to the genetics of the actual bee, said Yehuda Ben-Shahar, professor of biology in Arts & Sciences and corresponding author of the study published Oct. 14 in Science Advances. What we show is that it is genetic, but its the genetics of the bacteria.

Honey bees recognize and respond to chemical signals from other bees that they detect from skin compounds known as cuticular hydrocarbons, or CHCs. This study determined that a bees particular CHC profile is dependent on its microbiome the bacteria that make up its gut microbial community and is not something innate or genetic to the bee alone.

Different colonies do in fact have colony-specific microbiomes, which has never been shown before, said Cassondra L. Vernier, postdoctoral associate at the University of Illinois, who earned her biology PhD working with Ben-Shahar at Washington University.

Bees are constantly sharing food with one another and exchanging this microbiome just within their colony, said Vernier, first author of the new study.

Co-authors include Gautam Dantas, professor of pathology and immunology and of molecular microbiology at Washington University School of Medicine in St. Louis, and Joel Levine at the University of Toronto Mississauga. The work was conducted in part with bees housed at Tyson Research Center, the environmental field station for Washington University.

The importance of this paper is that its one of the first papers that actually shows that the microbiome is involved in the basic social biology of honey bees and not just affecting their health, Vernier said. The microbiome is involved in how the colony as a whole functions, and how they are able to maintain nest defenses, rather than just immune defense within an individual.

The gut microbial community or microbiome supplies humans and other animals with vitamins, helps digest food, regulates inflammation and keeps disease-causing microbes in check. Increasingly a topic of research interest, scientists have discovered many ways that the microbiome blurs the borders between a host and its bacteria.

The microbiome has been found to influence communication in several different organisms including, notably, large animals like hyenas.

For honey bees, this study shows that the microbiome plays a critical role in defining the tightly regulated chemical signals for group membership.

Until recently, most scientists thought that honey bees identified nestmates by picking up on a homogenized scent that they recognize from members of their own colony a kind of hive B.O., Ben-Shahar joked.

Bee colonies are usually composed of highly related individuals. But the chemical signals that allow bees to recognize each other are not determined by genetics alone. Researchers know this because baby bees can be placed into other colonies without being rejected up until a certain age and level of development.

It has to be something that they acquire during their lifetime that defines their nestmate recognition cues, Vernier said.

In previous work, Vernier and Ben-Shahar showed that bees develop different scent profiles as they age, and that gatekeeper bees respond differently to foragers returning to the hive compared with younger bees that have never ventured outside.

That research established a relationship between nestmate recognition and the clearly defined, age-dependent division of labor typical to honey bee hives.

Only when a bee is old enough to interact with others outside of the hive does it become recognizable to others. That was a clue for the researchers.

If you grow a honey bee in isolation, it will never develop a complete microbiome, Vernier said. It actually has to acquire most of it from interactions with other bees.

For this study, researchers determined that forager bees from different honey bee colonies have different gut microbial communities and CHC profiles by sequencing gut samples and analyzing cuticular extracts. The scientists also conducted cross-hive fostering experiments, raising groups of newly hatched bees in either their own colonies or unrelated colonies.

In the fostering experiments, the researchers found that both source- and host-colony related factors contribute to variations in the overall gut microbial community of individual bees. Of the 14 microbial taxa that significantly differed between treatments, six were similar between bees that shared the same hive environment while they grew up regardless of actual genetic relatedness.

The researchers also found that they could manipulate the microbiome of sister bees by feeding different microbes to newly hatched bees. In addition to developing different gut microbial communities, the bees also grew to have different CHC profiles.

They were unrecognizable to their siblings, Vernier said. Manipulating the microbiome was enough to cause sister bees to develop different scent profiles.

This new work is significant in part because it shows an integral role for the microbiome in the essential, everyday social interactions of honey bees, the Earths most important pollinators, researchers said.

For bees, some of the most complex aspects of their social behavior basically depends on bacteria more than anything else! Ben-Shahar said.

It doesnt matter how related they are, he said. Their ability to say you belong to this group basically depends on getting the right bacteria at the right time. Otherwise, they are blind to it.

And bee ID is key.

The biggest enemy to honey bees is other bees.

During fall, when plants stop producing nectar, there is a period of time when robbing is very prevalent in colonies, Vernier said. Robbing bees will find other colonies, and if theyre able to get in and take some honey, they will go back to their own nests and signal, Hey, go over there. Theres a nest thats not good at guarding, and we can steal their honey.

Robber bees will take that honey and leave the other colony to starve, she said. Its a very strong pressure.

Robbing deprives both the host bees and their associated bacteria with important resources which may have been the original drive to form this special bacteria-animal partnership, the researchers said.

Ben-Shahar and Verniers previous research with honey bees showed that graduating to forager status was a requirement for social membership. Read more.

Dear friend,

Of the hundreds of ice-creams I have eaten so far, the only one I remember is the ice-cream I never ate.

That was in 1993. My wife Richa and I were sitting outside a shop in the sweltering New Delhi. We had just bought an ice cream to cool down. From the corner of my eye, I saw a little boy who could use a few calories. I walked up to him and offered my cone that he gladly took. I have savored the gleam I saw in his eyes at least a dozen times since then.

In a very interesting study, researchers looked at the genetic fingerprint of the two types of happiness hedonistic (self-centric) and eudaimonic (other-centric). People who were hedonistically happy had a higher inflammatory and lower anti-viral gene expression. It was just the opposite for the eudaimonic ones. With many illnesses caused by inflammation, you can see why this is so important for our health.

My take on this research is that our genes and the immune system know what is right for us and society. In the current times when a healthy immune system is extremely important for us, promoting kindness is imperative.

Kindness, research shows, pays three times over. Your kind words and actions enhance your health and wellbeing, help others, and the memory of kind actions by itself enhances your wellbeing. A very simple way to enhance your self-worth and happiness today is to count your previous kind actions.

I suggest take out a pen and paper and write the three most selfless things you have done in your life. If you feel up to it, share your experience with someone. Just counting previous acts of kindness can enhance your self-worth and bring happiness to others (you guessed it right witnessing or hearing about others kind actions also increases happiness).

In kindness,

Amit

Our genes know kindness is the best medicine - Brainerd Dispatch

Culture-adapted AAV2 is a viral vector which is used to deliver gene therapy to the liver. However, clinical trials targeting diseases of the liver have had an 'unexpectedly low success rate' using the vector, according to researchers: who have now found that naturally occurring AAVs may be more effective.

The prototypical AAV2 discovered more than 50 years ago provides the serotype on which the field of AAV vectorology and gene therapy is based. The researchers from Australias Childrens Medical Research Institute (CMRI) say the discovery 'will shake the foundations of the field of AAV-based gene therapeutics and will mark the beginning of a new era not only for biomedical research, but most importantly, for millions of patients affected by genetic disorders'.

One area of interest in gene therapy is using AAVs to target the liver, which is involved in genetic disorders such as haemophilia and various enzyme deficiencies.

AAV2 is a viral vector used to deliver gene therapy to the liver, carrying therapeutic DNA to target cells in the body. It binds to a receptor on the target cell. However, the researchers found that while AAV2 binds to the attachment receptors - heparan sulfate proteoglycans (HSPCs) - it does so too tightly.

This means that the vector can get trapped on other cells in the body and not the target liver cells. This reduces the number of vectors that deliver their therapeutic cargo to the liver, diminishing therapeutic efficacy.

The teams of Dr Leszek Lisowski, Head of the Translational Vectorology Research Unit, and Prof Ian Alexander, Head of the Gene Therapy Research Unit, then turned to naturally occurring vectors isolated from liver samples. They found that these which use an as of yet unknown receptor are much more successful at delivering therapies to the liver.

CMRI researchers are now able to make vectors in the lab that use this better receptor, instead of HSPGs, potentially making the next generation of gene therapy targeting the liver 'vastly more successful'.

Theorizing that manufacturing methods could be playing a role, the researcherscompared traditional AAV vectors grown in culture with naturally occurring vectors that they isolated from liver samples. They observed that the cultured vectors rapidly mutated as they replicated in the lab: with these changes making the vectors bind more tightly to molecules called HSPGs on the surface of liver cells, but also impeding their ability to infect humanized liver cells in mice.

In contrast, the naturally occurring vectors infected liver cells more efficiently and bound less tightly to HSPGs, although these effects disappeared when the scientists grew the natural vectors in culture over time.

This really challenges a basic concept in our field that binding strongly to HSPG was essential for AAVs' entry into human cells and suggests that vectors targeting the other receptor used by natural AAVs, of human liver origin, are likely to be more effective for clinical gene therapy applications, said Dr Lisowski. The prototypical AAV2, discovered over 50yrs ago, is the serotype on which the entire field of AAV vectorology and gene therapy is based.

Our study sheds new light and challenges our previous understanding and corrects misconceptions about how the vector binds to the cells.

Researchers at the CMRI can now start to improve on the use of vectors to help children with liver conditions. A better vector can increase safety and improve efficiency, while the increased therapeutic efficacy will mean lower doses are needed and thus reduce the cost of treatment.

The insights on adeno-associated virus receptor binding can potentially be extended to other tissues beyond the liver, add researchers. This makes this a very impactful study which will change the trajectory of AAV-based gene therapies.

Adeno-associated viruses (AAVs) were discovered in the 1960s. The vectorization of AAV2, a human isolate, in 1984 set in motion the development the use of the viral vector in gene therapy.

The liver is a key target for developing more efficient AAV vector delivery, given its direct involvement in a number of genetic and acquired diseases.

(UroToday.com) Since 2015, multiple studies together have suggested that approximately a quarter of metastatic castration-resistant prostate cancer (mCRPC) tumors have mutations in DNA damage repair (DDR) genes. These alterations, especially those in genes for homologous recombination repair (HRR), are associated to varying degrees with response to PARP inhibitor therapy. Two PARP inhibitors are now approved for the care of patients with mCRPC and mutations in certain HRR genes: olaparib (based on PROfound trial) and rucaparib (based on TRITON2 trial). Given the significance of alterations in HRR genes in mCRPC, genomic testing for HRR alterations has been included in mCRPC treatment guidelines with the purpose of guiding genetic counseling and therapy selection.

In this poster, Dr. Neal Shore and colleagues describe real-world patterns and predictors of tissue testing for alterations in HRR genes. They focused on the community cancer care setting. Data were collected from the Flatiron Health Electronic Health Record derived database that was collected between 2013 and March 2019, prior to the approval of PARP inhibitor therapy in mCRPC, and focused on testing for alterations in BRCA1, BRCA2, ATM, CDK12, FANCA, and PALB2). The Flatiron database contains information on patient demographics, prostate cancer characteristics, and treatment, as well as genetic testing results.

From the Flatiron database, 5,213 patients with mCRPC were identified, 91% of which were managed at community oncology care centers. Of these patients, 674 (12.9%) underwent testing for the specified HRR gene alterations. Patient characteristics are shown below.

The breakdown of the 674 patients by testing method and number of genes tested is shown below.

BRCA1 and BRCA2 were the most commonly tested genes. A substantial portion of patients underwent only blood/saliva testing (40.5%, capable of detecting germline or circulating tumor DNA) or tumor-tissue testing only (42.1%, capable of detecting germline or tumor tissue DNA alterations). Only 1.8% of patients undergoing blood/saliva testing were tested for all 6 HRR genes, and 69% of tumor-tissue testing covered all 6 genes. Amongst the 286 patients who had negative blood/saliva testing, only 12.6% underwent tumor-tissue profiling, and 5 of these patients (13.9%) had an HRR alteration found.

The most common testing platform utilized was Foundation Medicine, followed by Guardant. Testing rates and the inclusion of more genes increased with time.

The prevalence of HRR alterations found is shown below.

Treatment at an academic medical center or having received multiple prior lines of therapy was associated with a higher likelihood of having HRR mutational profiling. Older age and higher PSA value at diagnosis of mCRPC were significantly associated with a lower likelihood of HRR mutation profiling.

The poster concludes that rates of HRR mutational testing did not increase dramatically with changes to the NCCN guidelines recommending this testing in 2017. Increased awareness of recommendations for testing, especially with the approval of two therapeutic agents contingent upon the presence of HRR alterations, is critical for the care of patients with mCRPC.

MIAMI, Sept. 22, 2020 /PRNewswire/ -- The Victor Center for the Prevention of Jewish Genetic Diseases, which offers preconception screening and genetic counseling for prospective parents, has recently expanded services to offer genetic screening and virtual clinical consults to couples and individuals in New York, New Jersey and Maryland.

The center, which also serves Florida, Massachusetts and Pennsylvania, helps future parents identify whether they are at risk of passing on genetic diseases, including those common among people of Jewish ancestry.

"Not everyone knows their full ancestral heritage, so we encourage anyone planning to start a family and their partner to undergo screening," said Debbie Wasserman, Outreach Coordinator/Genetic Counselor for the Victor Center.

Jewish genetic diseases are a group of recessive, inherited disorders that occur with significant frequency in the Ashkenazi Jewish community (those of eastern or central European descent). Individuals of Ashkenazi descent have higher carrier rates for diseases such as Tay-Sachs, Canavan, familial dysautonomia, and Gaucher. Many of the diseases are severe, and some are fatal in childhood.

One in two of those of Ashkenazi descent is a carrier for at least one Jewish genetic condition, and Sephardic and Mizrachi Jews are also at increased risk for certain genetic disorders. More than half of participants in the Victor Center screening program are carriers for one or more of the 225 plus conditions on the expanded screening panel, which also includes disorders found in other ethnicities.

The Victor Center offers a convenient screening process during this time of social distancing. Upon request, a genetic counseling session is scheduled and a screening kit is mailed to the home. Recipients provide saliva samples and return the kit to a lab for processing. Once results are available, a video consult is coordinated to convey understanding and address questions.

There is a fee for Victor Center screening services. However, most medical insurance plans cover the service. For more information, please call 786-897-9587 or visit http://www.victorcenter.org

About the Victor Center The Victor Center was founded in 2002 by Lois B. Victor in partnership with Einstein Healthcare Network in Philadelphia. Ms. Victor lost two children to a Jewish genetic disease before a test for the disorder became available. The experience galvanized her commitment to ensuring that no family endures the heartache of a preventable illness by making certain that Jews of childbearing age are screened and get the information they need to have healthy children. Nicklaus Children's Hospital was appointed the National Office for the Victor Center in 2017. The Nicklaus Children's Hospital Victor Center maintains the nation-wide collaborative work of the center in promoting education related to preconception screening while increasing knowledge, awareness, and access to genetic services.

About Nicklaus Children's HospitalFounded in 1950 by Variety Clubs International, Nicklaus Children's Hospital is South Florida's only licensed specialty hospital exclusively for children, with nearly 800 attending physicians and more than 475 pediatric subspecialists. The 309-bed hospital, known as Miami Children's Hospital from 1983 through 2014, is renowned for excellence in all aspects of pediatric medicine with several specialty programs routinely ranked among the best in the nation by U.S. News & World Report since 2008.

Its unusual that a virus would be less severe in children than it is in adults. But when it comes to COVID-19, kids make up just a small percentage of severe cases. Yale researchers are working to understand why that is.

Their discoveries can help guide understanding of the virus and possible treatment options.

Ina paper published recently in Proceedings of the National Academy of Sciences(PNAS),Dr. Naftali Kaminski, theBoehringer-Ingelheim Endowed Professor of Internal Medicine and chief of Pulmonary, Critical Care and Sleep Medicine, and colleagues shared findings related tochildrens surprising immunity to the virus. They detailed how factors including allergies, asthma, the common cold, and existing vaccines may be having a protective effect.

Meanwhile,Carrie Lucas, assistant professor of immunobiology at Yale, is looking at blood samples from the small percentage of children who develop the rare condition known as Multi-Inflammatory Syndrome in Children, or MIS-C, in response to COVID-19. Her lab is analyzing blood samples for molecular and genetic clues to figure out why a certain subset of kids are most at risk.

Findings just published in the journal Science Translational Medicine led byKevan Herold, the C.N.H. Long Professor of Immunology and Internal Medicine at Yale, revealed that children diagnosed with COVID-19 express higher levels of two specific immune system molecules, a factor that might be leading to better health outcomes.

Understanding why children appear to be better protected from severe cases than adults could provide important clues on how the novel coronavirus spreads, who is at greatest risk, and how to treat it.

This is different from other viruses that affect kids more seriously, Kaminski said. Its an interesting conundrum and could provide implications for therapeutics.

In the PNAS paper, researchers point to the possibility that allergies and asthma in children has a protective effect. When the body responds to an allergy or asthma trigger, the immune system releases Th2 cells, which in turn increases a type of cell called the eosinophil in the blood and tissues. This allergic inflammation has been shown to dramatically reduce the levels of a key receptor to the COVID-19 molecule, known as ACE2. They added that astudy of 85 older adultswho died of COVID-19 in China showed that they had very low levels of blood eosinophils.

Initially, there was a concern about the impact of COVID-19 on children with asthma, said Kaminski. Some 7.5% of U.S. children under 18, or 5.5 million kids, have asthma, according to the Centers for Disease Control and Prevention. But, in fact, it seems that compared to other chronic lung diseases, people with asthma are infected less, and, when they are infected, asthma is not a risk factor.

Instead, risk factors known to drive worse COVID-19 outcomes include age, obesity, hypertension, and cardiac diseases.

The greater exposure children have to the common cold may also offer protection. Coronaviruses are a large family of viruses so named for their crown-like shape under a microscope, of which the common cold is one. SARS-CoV-2, which causes COVID-19, is another.

It is thought that exposure to colds may cause viral interference, when one virus interferes with the replication of a second virus. Exposure to common colds, and more severe illnesses like croup, more common in children, are associated with decreased expression of the ACE2 COVID-19 receptor. Studies have found that children symptomatic with COVID-19 may have high viral loads in their noses but, because they have lower levels of ACE2, their lungs are less likely to become infected. In other words, they can still easily spread the virus, but are less likely to develop serious symptoms.

Kaminski added that there is even evidence that vaccines can provide protection. Astudyof Department of Defense personnel found that the 2017-2018 seasonal flu vaccine produced a statistically significant number of individuals who tested positive for common cold-related coronaviruses. If future flu vaccines are designed to increase common coronaviruses, he said, this phenomenon may actually provide some protection to SARS-CoV-2 through cross-reactive immunity.

Of course, not all children are protected from the worst effects of COVID-19. Lucas and her team of pediatric immune disease researchers at Yale are looking at the rare cases of children who have been seriously affected by the virus. Specifically, they looked at children who were asymptomatic during SARS-CoV-2 infection, but weeks later developed a high fever, vomiting, abdominal pain, and sometimes shock, a condition known as MIS-C.As of Sept. 17, there were 935 confirmed cases of MIS-C in the U.S., and 19 deaths.

Lucas lab, which has enrolled 16 pediatric MIS-C patients, is analyzing immune cells in their blood at the single-cell level, as well as thousands of blood proteins, to understand what is happening.

Mostly, right now, our data are showing what the syndrome isnot, she said. For instance, we have found no sign of an active viral or bacterial infection during acute MIS-C.

They are also collecting saliva samples from parents to compare to childrens samples, which might reveal information about genetic variants. Were looking for the needle in the haystack that could be causing this rare manifestation, Lucas said. So far, theres no evidence that this is something that runs in families. I dont know of any cases where two children in a family developed MIS-C.

What they do know, she said, is that inflammatory markers are high, and most patients respond well to immunosuppressive therapies such as steroids. Additional findings will be published in the coming weeks on MedRxiv, a preprint server founded by Yale scientists which publishes studies before they have been peer-reviewed.

While children largely seem to be protected from the immediate effects of COVID-19, there are still long-term concerns, Kaminski and the authors caution. The pandemic and social distancing, they note, affect maturation of the immune system, psychological health, education, and childhood obesity.

We know that the health of children is strongly affected by socioeconomic downturns, Kaminski said, and this potential adverse outcome should not be overlooked.

What we know about COVID-19 and kids - Yale News

ZUG, Switzerland and CAMBRIDGE, Mass. and BOSTON, Sept. 22, 2020 (GLOBE NEWSWIRE) -- CRISPR Therapeutics (Nasdaq: CRSP) and Vertex Pharmaceuticals Incorporated(Nasdaq: VRTX) today announced the European Medicines Agency (EMA) has granted Priority Medicines (PRIME) designation to CTX001, an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited therapy for the treatment of severe sickle cell disease (SCD).

PRIME is a regulatory mechanism that provides early and proactive support to developers of promising medicines, to optimize development plans and speed up evaluations so these medicines can reach patients faster. The goal of PRIME is to help patients benefit as early as possible from innovative new therapies that have demonstrated the potential to significantly address an unmet medical need. PRIME designation was granted based on clinical data from CRISPR and Vertexs ongoing Phase 1/2 trial of CTX001 in patients with severe SCD.

About CTX001CTX001 is an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited therapy that is being evaluated for patients suffering from transfusion-dependent beta thalassemia (TDT) or severe SCD, in which a patients hematopoietic stem cells are engineered to produce high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is a form of the oxygen-carrying hemoglobin that is naturally present at birth, which then switches to the adult form of hemoglobin. The elevation of HbF by CTX001 has the potential to alleviate transfusion requirements for TDT patients and reduce painful and debilitating sickle crises for SCD patients.

Based on progress in this program to date, CTX001 has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, and Orphan Drug designations from the U.S. Food and Drug Administration (FDA), and Orphan Drug Designation from the European Commission, for both TDT and SCD.

CTX001 is being developed under a co-development and co-commercialization agreement between CRISPR Therapeutics and Vertex. CTX001 is the most advanced gene-editing approach in development for TDT and SCD.

About CLIMB-111The ongoing Phase 1/2 open-label trial, CLIMB-Thal-111, is designed to assess the safety and efficacy of a single dose of CTX001 in patients ages 12 to 35 with TDT. The trial will enroll up to 45 patients and follow patients for approximately two years after infusion. Each patient will be asked to participate in a long-term follow-up trial.

About CLIMB-121The ongoing Phase 1/2 open-label trial, CLIMB-SCD-121, is designed to assess the safety and efficacy of a single dose of CTX001 in patients ages 12 to 35 with severe SCD. The trial will enroll up to 45 patients and follow patients for approximately two years after infusion. Each patient will be asked to participate in a long-term follow-up trial.

About the Gene-Editing Process in These TrialsPatients who enroll in these trials will have their own hematopoietic stem and progenitor cells collected from peripheral blood. The patients cells will be edited using the CRISPR/Cas9 technology. The edited cells, CTX001, will then be infused back into the patient as part of a stem cell transplant, a process which involves, among other things, a patient being treated with myeloablative busulfan conditioning. Patients undergoing stem cell transplants may also encounter side effects (ranging from mild to severe) that are unrelated to the administration of CTX001. Patients will initially be monitored to determine when the edited cells begin to produce mature blood cells, a process known as engraftment. After engraftment, patients will continue to be monitored to track the impact of CTX001 on multiple measures of disease and for safety.

About the CRISPR-Vertex CollaborationCRISPR Therapeutics and Vertex entered into a strategic research collaboration in 2015 focused on the use of CRISPR/Cas9 to discover and develop potential new treatments aimed at the underlying genetic causes of human disease. CTX001 represents the first treatment to emerge from the joint research program.
