Hiltzik: A judge undermines the FDA on stem cells – Los Angeles Times

Posted: October 4, 2022 at 2:11 am

A federal judge in Riverside declared a California stem cell treatment firm to be exempt from Food and Drug Administration regulations, opening the door to the further proliferation of clinics offering therapies the FDA says are scientifically unproven and potentially dangerous.

In the ruling issued late Tuesday, Judge Jesus G. Bernal of Riverside declined to block California Stem Cell Treatment Center from continuing to offer purported stem cell treatments to customers.

Bernal accepted the centers position that its treatments qualified for an exception from FDA regulations, in part because they were tantamount to surgical procedures.

Stem cells have been called everything from cure-alls to miracle treatments. But dont believe the hype.

Food and Drug Administration warns public against unproven stem cell treatments

Bernals ruling, which came more than a year after a seven-day trial in May 2021 and closing arguments last August, potentially undermines a years-long FDA crackdown on clinics claiming that stem cells can treat or cure conditions including orthopedic injuries, Alzheimers and Parkinsons diseases, multiple sclerosis, and erectile dysfunction.

The defendants are engaged in the practice of medicine, Bernal ruled, not the manufacture of pharmaceuticals.

The FDA regulations, however, define drugs much more broadly than the manufacture of pharmaceuticals rather, as any article that is intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease. Any such articles, the agency says, must have agency approval and the California centers treatments do not.

To me, the language of his ruling sounded almost like it was written by the defendants, Paul S. Knoepfler, a UC Davis stem cell biologist who has been tracking the proliferation of such clinics for years, observed in his laboratory blog.

The Bernal ruling will not be a good thing for careful oversight of stem cell clinic practices, Knoepfler said. Its concerning to think about more people being put at risk.

Knoepfler suggested that the FDA would feel duty-bound to appeal Bernals ruling in order to protect its regulatory campaign, and because it conflicts with federal court rulings in a nearly identical case the FDA brought against Florida clinics in Miami federal court.

The agency told me by email that it is reviewing the courts decision and does not have further comment at this time.

Bioethicist Leigh Turner of UC Irvine, who has collaborated with Knoepfler on tracking the growth of the stem cell clinic industry, agreed that Bernals ruling is an enormous setback for the FDA in an area where theyve struggled for many years.... For people who work in this industry, its great news. But not for anyone concerned about patient safety, misinformation or disinformation.

As part of its crackdown, the FDA has written hundreds of letters warning stem cell clinics that theyre violating the law, and has pursued some in court.

After issuing regulations in 2017 declaring that treatments using unproven stem cell therapies were illegal, the FDA suspended its enforcement for more than three years to give clinic operators time to comply with FDA rules. The agencys forbearance, however, opened the door to a further proliferation of suspect clinics.

By March 2021, according to a survey by Turner, nearly 1,500 U.S. businesses were pitching the suspect treatments at more than 2,700 clinics, reflecting a torrent of openings since 2016, when Turner and Knoepfler jointly started tracking the field.

More than four times as many businesses than were identified five years ago are selling stem cell products that are not FDA-approved and lack convincing evidence of safety and efficacy, Turner wrote last year.

Some clinics have charged customers more than $10,000 for the unproven treatments, plying the customers with unsupported claims of medical success. The fees are seldom, if ever, covered by health insurance. Some treatments resulted in serious medical complications.

The FDA also has warned the public that some patients seeking cures and remedies are vulnerable to stem cell treatments that are illegal and potentially harmful.

The FDA has approved stem cell treatments only for disorders of the blood-producing, or hematopoietic, system. No other stem cell treatment claims have been scientifically validated, the agency says.

Stem cells have been called everything from cure-alls to miracle treatments, the agency says in its public warning. But dont believe the hype.

Bernals ruling conflicts with a 2019 decision by U.S. District Judge Ursula Ungaro of Miami, who ordered a Florida clinic shut down after the FDA asserted that its purported stem cell therapies were scientifically unproven and illegal.

Ungaros decision was upheld last year by the 11th Circuit U.S. Court of Appeals, which found that the clinics claim of exemption from FDA regulation on grounds similar to those claimed by the California center, didnt apply. No reasonable fact-finder could disagree, the three-judge appellate panel ruled.

As it happens, in its finding the appellate panel specifically rejected an earlier ruling by Bernal, in which he denied the FDAs request for a preliminary injunction against the California center and set the case for trial. The appellate ruling isnt binding precedent for federal courts outside the 11th Circuit, which covers parts of the Southeast.

The FDAs lawsuits against the Florida clinic and the California center were almost identical and filed on the same day, May 9, 2018. In both cases, the agency asserted that the clinics were in effect purveying illegal drugs as defined by federal law.

The lawsuits were part of an agency effort to clamp down on the burgeoning trade in stem cell-related therapies. The California lawsuit named the centers founders, Elliott Lander and Mark Berman, as defendants. Berman died in April

The California Stem Cell Treatment Center has operated clinics in Beverly Hills and Rancho Mirage, and provides treatment protocols and other assistance to other clinics around the country.

In its Florida and California lawsuits, the FDA targeted a widespread practice utilized by both clinics in which fat cells are extracted from a customer by liposuction. The extraction is treated to produce a fluid purportedly rich in stem cells known as a stromal vascular fraction or SVF, which is injected back into the same subject.

Both sets of defendants asserted in their defense that their activities qualified for exceptions from FDA drug regulations afforded to surgical procedures involving the use of a patients own tissues as well as the use of minimally manipulated tissues. The agencys position is that the fat extractions are so heavily treated before the reinjections that the treatments fall outside those exceptions.

In his ruling, Bernal drew extensively and verbatim from California Stem Cell Treatment Centers proposed findings of facts and scarcely at all from the FDAs proposal. His ruling incorporated several scientific errors, according to Knoepfler.

For example, Bernal accepted the centers assertion that unlike manufactured drugs, the SVF Surgical Procedure does not create any cellular or tissue-based product that did not previously exist within the patient.

In fact, Knoepler says, there is no equivalent of SVF already in the body.

Mesoblast Submits New Information to FDA IND File in Response to Items in the CRL to the Remestemcel-L BLA for SR-aGVHD – GlobeNewswire

Posted: October 4, 2022 at 2:11 am

NEW YORK, Oct. 02, 2022 (GLOBE NEWSWIRE) -- Mesoblast Limited (Nasdaq:MESO; ASX:MSB), global leader in allogeneic cellular medicines for inflammatory diseases, announced today that it has submitted to the U.S. Food and Drug Administration (FDA) substantial new information on clinical and potency assay items identified in the Complete Response Letter (CRL) received from FDA in September 2020 to the Biologics License Application (BLA) for remestemcel-L in the treatment of children with steroid-refractory acute graft versus host disease (SR-aGVHD).

Mesoblast has maintained an active dialog with the FDA since receiving the CRL, and the substantial new information submitted to the Investigational New Drug (IND) file for remestemcel-L in the treatment of children with SR-aGVHD, as guided by FDA, represents a major milestone in the Companys complete response to the FDA. Remestemcel-L has been granted Fast Track Designation and BLA Priority Review from the FDA.

Survival outcomes have not improved over the past two decades for children or adults with the most severe forms of SR-aGVHD.1-3 The lack of any approved treatments for children under 12 means that there is an urgent need for a therapy that improves the dismal survival outcomes in children.

The submission summarizes controlled data providing further evidence of remestemcel-Ls ability to save lives, said Dr. Silviu Itescu, Chief Executive of Mesoblast. Additionally, the improved process controls we have put in place to assure robust and consistent commercial product, together with a potency assay that predicts consistent survival outcomes, makes remestemcel-L a compelling treatment for these children.

About Steroid-refractory Acute Graft Versus Host Disease Acute GVHD occurs in approximately 50% of patients who receive an allogeneic bone marrow transplant (BMT). Over 30,000 patients worldwide undergo an allogeneic BMT annually, primarily during treatment for blood cancers, including about 20% in pediatric patients.4,5 SR-aGVHD is associated with mortality as high as 90% and significant extended hospital stay costs.6,7 There are currently no FDA-approved treatments in the US for children under 12 with SR-aGVHD.

About Mesoblast Mesoblast is a world leader in developing allogeneic (off-the-shelf) cellular medicines for the treatment of severe and life-threatening inflammatory conditions. The Company has leveraged its proprietary mesenchymal lineage cell therapy technology platform to establish a broad portfolio of late-stage product candidates which respond to severe inflammation by releasing anti-inflammatory factors that counter and modulate multiple effector arms of the immune system, resulting in significant reduction of the damaging inflammatory process.

Mesoblast has a strong and extensive global intellectual property portfolio with protection extending through to at least 2041 in all major markets. The Companys proprietary manufacturing processes yield industrial-scale, cryopreserved, off-the-shelf, cellular medicines. These cell therapies, with defined pharmaceutical release criteria, are planned to be readily available to patients worldwide.

Mesoblast is developing product candidates for distinct indications based on its remestemcel-L and rexlemestrocel-L allogeneic stromal cell technology platforms. Remestemcel-L is being developed for inflammatory diseases in children and adults including steroid refractory acute graft versus host disease, biologic-resistant inflammatory bowel disease, and acute respiratory distress syndrome. Rexlemestrocel-L is in development for advanced chronic heart failure and chronic low back pain. Two products have been commercialized in Japan and Europe by Mesoblasts licensees, and the Company has established commercial partnerships in Europe and China for certain Phase 3 assets.

15 Years of Heart – Newswise

Posted: October 4, 2022 at 2:11 am

Newswise LOS ANGELES (Oct. 3, 2022) --Pioneering heart care is a tradition at Cedars-Sinai. Its a tradition that took root in 1924, when Cedars-Sinai became home to the first electrocardiogram machine in Los Angeles.

The roots grew stronger in the 1970s, when two Cedars-Sinai cardiologists invented the game-changing Swan-Ganz catheter. And stronger still in 2007, when Cedars-Sinai founded what is today theSmidt Heart Institute.

On the occasion of the institutes 15thanniversary, the Cedars-Sinai Newsroom sat down withEduardo Marbn, MD, PhD, executivedirector of theSmidt Heart Institute and the Mark Siegel Family Foundation Distinguished Professor, to get his views on the state of cardiac medicine.

Newsroom: What are the advances youve seen in heart medicine over the past 15 years?Marbn:We've been able to really address programs from the point of view of the need of the patient. One thing we've excelled at, for example, is helping our patients with advanced heart diseaseheart failure so severe that they're facing either highly experimental stem cell treatments or heart transplantation. And these are two areas in which we've excelled, become the world leader in the number and also in the outcomes of heart transplants for those patients who need them. And we've also made quite a lot of progress in the area of regenerative medicine.

When the Heart Institute was established 15 years ago, almost all valvular problems in the heart or major structural problems required opening the chest surgically. Putting a patient on cardiopulmonary bypass. Fixing the problem in an operating room. And then keeping the patient in the hospital for about a week. In the past 15 years, the management of valvular heart disease has been completely transformed so that things that used to take that long and were that complicated can now be done as overnight therapy, using just a catheter inside the heart, and no opening of the chest.

We've led the way in the development of these technologies. We've done more such procedures than any other center in the United States.

Newsroom: How much has the Smidt Heart Institute grown?Marbn:Over the last 15 years, the Heart Institute has seen an incredible increase in volume. We have gone from doing 25 thoracic transplants a year, meaning either lung or heart or both, to doing over 200 now, with outstanding outcomes. We have gone from doing about 3,000 catheter-based procedures a year, to 13,000 a year.

We have gone up in our U.S. News and World Report (Best Hospitals) ranking nationally, from #17 Heart Program and #5 in the western U.S. to now being #1 in the western U.S. for the past 10 years and to being the third-ranked program nationally for the last four years.

Newsroom: Also during that time, theBarbra Streisand Womens Heart Centerin the Smidt Heart Institute has pioneered a lot of work on sex differences in heart disease.Marbn:The Smidt Heart Institute has come to be known as the world leader in a number of areas. One of those is in women's heart disease. In the last 15 years, we've really become recognized as a go-to destination for teaching, research and training. We've trained generations of researchers and physicians who are going into this field, and we've discovered that women are not the same as men and the way they manifest their heart disease. Nor are the treatments necessarily likely to work equally in men and in women.

Newsroom: What lessons were learned from the COVID-19 pandemic?Marbn:When the pandemic of COVID-19 started early in 2020, we were among the first to codify the cardiac complications that are associated with the disease. For example, myocarditis and other forms of acute manifestations and the long-running complications that have to do with long COVID. We were among the first to describe these situations. And since then, we've been at the forefront of studying the cardiac complications of COVID-19 in communities.

For example, we have a large ongoing study looking at a large number of community-based participants that then develop COVID-19 and some of whom go on to develop heart disease. We're asking questions like, how does the heart disease manifest itself? Who's at highest risk? What can we do about it? And of course, we're in the data collection stage more than in the answer formulation stage, but we've really tried to get ahead of it rather than just being observers.

Newsroom: What kind of progress do you expect in the next 15 years?Marbn:It's mind boggling to imagine what might happen over the next 15. But for sure, among the trends that we've seen there will continue miniaturization. We believe that it's very likely that major equipment that is now required, for example, to sustain the heart artificiallyluggage sized pumps that need to be plugged in periodically to batteriesfor example, as an external pump for the heart. These things will be miniaturized and implanted.

We're going to see an enormous rise in the maturation and ability of biological therapies, gene-based and cell-based therapies, to address heart disease in a very fundamental way that actually changes the disease rather than just reacts to it. And of course, we're getting better at prevention and also the understanding of how disease is manifested differently in men and in women, as well as in various socioeconomic groups.

Newsroom: Is there a single achievement of which you are most proud?Marbn:The signature accomplishment of the Smidt Heart Institute has been proof of principle that by bringing together diverse specialists from different backgrounds into one setting, that we can improve patient care and our understanding of disease. What we've done here is created a model for how cardiology and cardiac surgery should work together to transform the care and the knowledge about illness as we move forward.

QC Kinetix (The Heights) Helping Patients Heal Better from Joint Pain Through Houston Heights Sports Medicine – Yahoo Finance

Posted: October 4, 2022 at 2:11 am

Houston, TX - (NewMediaWire) - October 03, 2022 - Joint pain is one of the leading causes of discomfort among the American populace. It is estimated that more than 65 million American adults suffer from low back pain, while over 16 million deal with acute or chronic joint pain due to arthritis. The number seems to be growing at an alarming rate annually, with the problem spreading to more young adults due to their lifestyle choices, occupation, accidents, and other reasons. QC Kinetix (The Heights) estimates that a whopping number of Americans will be battling chronic joint pain in years to come if no real step is taken.

As a pain control clinic focusing on health and wellness, QC Kinetix (The Heights) understands the health problems associated with heavy medication use to combat joint pain. The lead treatment provider at the clinic noted that more people who depend on medication for pain relief are growing tired and abandoning it because of its negative side effects on their bodies and organs. Others are too scared to consider surgical interventions which offer no real promises of long-term health benefits.

In the face of these health challenges, QC Kinetix (The Heights) is offering a better solution with better healing potential to patients suffering from joint pain and related problems. Speaking on their natural treatment therapies, the clinic's spokesperson maintained that they offer a minimally invasive and natural treatment solution that helps patients avoid the costs, risks, and complications associated with surgeries. He added that their treatment plan is also devoid of medication use, which means patients can significantly dump the unhealthy habit of medication consumption while improving their health and wellness through other natural means.

The clinic's spokesperson noted that their sports and regenerative medicine treatment focuses on each patient's challenges and finds a way to improve their body's natural healing abilities. Speaking on the treatment modality's effectiveness for Houston Heights back pain treatment, Scott Hoots said: "In our QC Kinetix The Heights regenerative medicine clinics, we serve our patients by providing leading regenerative therapies that reduce joint pain associated with direct trauma, a sports-related injury, or a degenerative medical condition. These techniques target the impacted area to reduce inflammation and repair damaged tissue. Our team of medical professionals receives the highest quality training and research to provide our clients with the latest therapies to alleviate their ailments. In addition, we pride ourselves on providing the highest level of respect and care for our clients, as returning their ability to live with pain relief is our primary goal."

Each patient coming into the clinic will have access to a personalized health and wellness service centered around their needs. The treatment providers offer an initial consultation service where they get to learn more about the patient's health, symptoms, past treatments, allergies, and other information. Patients will also have access to a comprehensive examination and physical assessment for diagnostic purposes. Once diagnosed, the team will determine the patient's suitability for the treatment and develop a personalized treatment plan to alleviate their pain and discomfort while equipping the body with the needed building blocks for long-term health and wellness.

Welcoming Houston residents to schedule an appointment, the lead treatment provider at the clinic noted that regenerative medicine offers a wide range of benefits to patients. He maintained that several of their patients have been able to save money and avoid the complications of surgical intervention through their natural treatment plans. He further noted that their minimally invasive treatments are low risks and require a shorter recovery time compared to surgeries. Using stem cell therapy, platelet-rich plasma therapy, Class IV laser therapy, and others, patients will also enjoy positive health benefits like reduced inflammation, pain relief, improved healing, and a better range of motion from the affected joints.

QC Kinetix (The Heights) is currently taking new patients as its appointment slots are filling up fast. The pain control clinic can be reached via phone at (713) 913-5285 or via its website. The clinic is located at 1900 North Loop West, Suite 300, Houston, TX, 77018, US.

Sources – Minnesota Timberwolves’ Karl-Anthony Towns was on bed rest for days due to throat infection – ESPN

Posted: October 4, 2022 at 2:11 am

Minnesota Timberwolves star Karl-Anthony Towns was hospitalized last week with a throat infection that caused him trouble breathing and forced him to be on bed rest for days, sources told ESPN.

Towns spoke to the media Monday for the first time since falling ill and said his weight was down to 231 pounds (he's listed at 248), but he didn't reveal the nature of the non-COVID-19 illness.

Towns, who missed all of the Timberwolves' training camp, said he didn't get clearance to walk again until Saturday, when he attended a team event.

"I'm still recovering. I'm still getting better," Towns told reporters in Minneapolis before the team left on a 10-day preseason road trip. "There was more drastic things to worry about than basketball [during the illness]."

Timberwolves coach Chris Finch said Monday that Towns wouldn't play in Tuesday's preseason opener against the Heat in Miami as he works on ramping up his conditioning. During the offseason, Towns had stem-cell treatments and platelet-rich plasma injections in both knees, his left ankle, left wrist and right finger. He also signed a four-year, $224 million contract extension, tying him to the team for the next five seasons.

Towns averaged 24.6 points, 9.8 rebounds and shot 41% on 3-pointers last season, when he was named to the All-NBA team.

Overview

Stem cells have the ability to divide for indefinite periods in culture and give rise to multiple specialized cell types. They can develop into blood, neurons, bone, muscle, skin and other cell types. They have emerged as a major tool for research into the causes of ALS, and in the search of new treatments.

Types of Stem Cells:

The field of stem cell research is progressing rapidly, and The ALS Association is spearheading work on several critical fronts. The research portfolio supports innovative projects using IPSCs for drug development and disease modeling. The Association is supporting an IPSC core at Cedars-Sinai Medical Center providing access to lines for researchers globally. Several of the big data initiatives are collecting skin cells or blood for IPSC generation, such as Genomic Translation for ALS Clinical Care (GTAC), Project MinE, NeuroLINCS and Answer ALS. The ALS Association also sponsors pre-clinical studies and pilot clinical trials using stem cell transplant approaches to develop the necessary tools for stem cell transplant studies and to improve methods for safety and efficiency. We also support studies that involve isolating IPSCs to develop biomarkers for clinical trials through ALS ACT. In addition, the retigabine clinical trial that we sponsor uses iPSCs derived from participants in parallel with clinical data to help test whether the drug has the desired effect.

Stem cells are being used in many laboratories today for research into the causes of and treatments for ALS. Most commonly, researchers use iPSCs to make a unique source of motor neurons from individual ALS patients to try to understand why and how motor neurons die in ALS. Two types of motor neurons are affected in ALS are upper coriticospinal motor neurons, that when damaged, cause muscle spasticity (uncontrolled movement), and lower motor neurons, that when damaged, cause muscle weakness. Both types can be made from iPSCs to cover the range of pathology and symptoms found in ALS. Astrocytes, a type of support cell, called glia, of the central nervous system (CNS), are also being generated from iPSCs. It is well established that glia play a role in disease process and contribute to motor neuron death.

Motor neurons created from iPSCs have many uses. The availability of large numbers of identical neurons, made possible by iPSCs, has dramatically expanded the ability to search for new treatments. For example, they can also be used to screen for drugs that can alter the disease process. Motor neurons derived from iPSCs can be genetically modified to produce colored fluorescent markers that allow clear visualization under a microscope. The health of individual motor neurons can be tracked over time to understand if a test compound has a positive or negative effect.

Because iPSCs can be made from skin samples or blood of any person, researchers have begun to make cell lines derived from dozens of individuals with ALS. One advantage of iPSCs are that they capture a persons exact genetic material and provide an unlimited supply of cells that can be studied in a dish, which is like persons own avatar. Comparing the motor neurons derived from these cells lines allows them to ask what is common, and what is unique, about each case of ALS, leading to further understanding of the disease process. They are also used to correlate patients clinical parameters, such as site of onset and severity with any changes in the same patients motor neurons.

Stem cells may also have a role to play in treating the disease. The most likely application may be to use stem cells or cells derived from them to deliver growth factors or protective molecules to motor neurons in the spinal cord. Clinical trials of such stem cell transplants are in the early stages, but appear to be safe. In addition, transplantation of healthy astrocytes have the potential to be beneficial in supporting motor neurons in the brain and spinal cord.

While the idea of replacing dying motor neurons with new ones derived from stem cells is appealing, using stem cells as a delivery tool to provide trophic factors to motor neurons is a more realistic and feasible approach. The significant challenge to replacing dying motor neurons is making the appropriate connections between muscles and surrounding neurons.

Isolation of IPSCs from people with ALS in clinical trials is extremely valuable for the identification of unique signatures in the presence or absence of a specific treatment approach and as a read out to test whether a drug or test compound has an impact on the health of motor neurons and/or astrocytes. A positive result gives researchers confidence to move forward to more advanced clinical trials. For example, The ALS Association is currently funding a clinical trial to test the effects of retigabine on motor neurons, which use the enrolled patients individual iPSCs lines derived from collected skin samples and testing whether there is a change in the excitability of motor neurons in people with ALS.

Therapeutic Solutions International Identifies CD103 Expressing Dendritic Cells and Exosomes Thereof as Novel Mechanism for JadiCell Mesenchymal Stem…

Posted: October 4, 2022 at 2:09 am

ELK CITY, Idaho--(BUSINESS WIRE)--Therapeutic Solutions International (TSOI) announced today new data suggesting that therapeutic effects of its universal donor stem cell product are mediated in part through CD103 expressing dendritic cells.

In a series of experiments, it was found that protection against both Chronic Obstructive Pulmonary Disease (COPD) and Acute Respiratory Distress Syndrome (ARDS) could be transferred to nave mice by dendritic cells expressing the molecule CD103. Furthermore, exosomes, which are nanoparticles produced by cells, were capable of transferring protection to nave mice.

I am pleased to have worked with a team of opinion leaders that are at the cutting edge to have discovered this quite unexpected finding, said Dr. James Veltmeyer, Chief Medical Officer of the Company. While the field of exosome therapeutics is growing exponentially, the use of dendritic cell exosomes for respiratory conditions is completely unheard of.

Therapeutic Solutions International is currently running a Phase III clinical trial using JadiCells in the treatment of COVID-19 associated ARDS. Additionally, the Company has an Investigational New Drug Application IND# 28508 for treatment of COPD, for which the Company is still in discussions with the FDA.

Dr. Veltmeyer has performed unparalleled work in advancing both clinical translation of the JadiCell, as well as leveraging scientific lessons learned from our cancer program to identify a new mechanism by which our cells exert this previously unknown therapeutic efficacy, said Timothy Dixon, President, and CEO of the Company. Having filed our patent today on this new finding, we anticipate potential development of adjuvant products around dendritic cell generated exosomes.

Biopharma focuses on streamlining biomanufacturing and supply chain issues to drive uptake of cell and gene therapies.

Cell and gene therapies (CGTs) offer significant advances in patient care by helping to treat or potentially cure a range of conditions that have been untouched by small molecule and biologic agents. Over the past two decades, more than 20 CGTs have been approved by FDA in the United States and many of these one-time treatments cost between US$375,00 and US$2 million a shot (1). Given the high financial outlay and patient expectations of these life-saving therapies, it is essential that manufacturers provide integrated services across the whole of the supply chain to ensure efficient biomanufacturing processes and seamless logistics to reduce barriers to uptake.

The following looks at the who, what, when, and why of biomanufacturing and logistics in CGTs in the bio/pharmaceutical industry in more detail.

According to market research, the global gene therapy market will reach US$9.0 billion by 2027 due to favorable reimbursement policies and guidelines, product approvals and fast-track designations, growing demand for chimeric antigen receptor (CAR) T cell-based gene therapies, and improvements in RNA, DNA, and oncolytic viral vectors (1).

In 2020, CGT manufacturers attracted approximately US$2.3 billion in investment funding (1). Key players in the CGT market include Amgen, Bristol-Myers Squibb Company, Dendreon, Gilead Sciences, Novartis, Organogenesis, Roche (Spark Therapeutics), Smith Nephew, and Vericel. In recent years, growth in the CGT market has fueled some high-profile mergers and acquisitions including bluebird bio/BioMarin, Celgene/Juno Therapeutics, Gilead Sciences/Kite, Novartis/AveXis and the CDMO CELLforCURE, Roche/Spark Therapeutics, and Smith & Nephew/Osiris Therapeutics.

Many bio/pharma companies are re-considering their commercialization strategies and have re-invested in R&D to standardize vector productions and purification, implement forward engineering techniques in cell therapies, and improve cryopreservation of cellular samples as well as exploring the development of off-the-shelf allogeneic cell solutions (2).

The successful development of CGTs has highlighted major bottlenecks in the manufacturing facilities, and at times, a shortage of raw materials (3). Pharma companies are now taking a close look at their internal capabilities and either investing in their own manufacturing facilities or outsourcing to contract development and manufacturing organizations (CDMOs) or contract manufacturing organizations (CMOs) to expand their manufacturing abilities (4). Recently, several CDMOsSamsung Biologics, Fujifilm Diosynth, Boehringer Ingelheim, and Lonzahave all expanded their biomanufacturing facilities to meet demand (5).

A major challenge for CGT manufacturers is the seamless delivery of advanced therapies. There is no room for error. If manufacturers cannot deliver the CGT therapy to the patient with ease, the efficacy of the product becomes obsolete. Many of these therapies are not off-the-shelf solutions and therefore require timely delivery and must be maintained at precise temperatures to remain viable. Thus, manufacturers must not only conform to regulations, but they must also put in place logistical processes and contingency plans to optimize tracking, packaging, cold storage, and transportation through the products journey. Time is of the essence, and several manufacturers have failed to meet patient demands, which have significant impacts on the applicability of these agents.

Several CAR T-cell therapies have now been approved; however, research indicates that a fifth of cancer patients who are eligible for CAR-T therapies pass away while waiting for a manufacturing slot (6). Initially, the manufacture of many of these autologous products took around a month, but certain agents can now be produced in fewer than two weeks (7). Companies are exploring new ways to reduce vein-to-vein time (collection and reinfusion) through the development of more advanced gene-transfer tools with CARs (such as transposon, CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) among others, and the use of centralized organization with standardized apheresis centers (5). Others are exploring the use of the of allogeneic stem cells including Regen Biopharma, Escape Therapeutics, Lonza, Pluristem Therapeutics, and ViaCord (7).

Several gene therapies have also been approved, mainly in the treatment of rare disease (8). Many companies are evaluating novel gene therapy vectors to increase levels of gene expression/protein productions, reduce immunogenicity and improve durability including Astellas Gene Therapies, Bayer, ArrowHead Pharmaceuticals, Bayer, Bluebird Bio, Intellia Therapeutics, Kystal Biotech, MeiraGTx, Regenxbio, Roche, Rocket Pharmaceuticals, Sangamo Therapeutics, Vertex Pharmaceuticals, Verve Therapeutics, and Voyager Therapeutics (8).

While many biopharma companies have established their own in-house CGT good manufacturing practice (GMP) operation capabilities, others are looking to decentralize manufacturing and improve distribution by relying on external contracts with CDMOs and CMOs such as CELLforCURE, CCRM, Cell Therapies Pty Ltd (CTPL), Cellular Therapeutics Ltd (CTL), Eufets GmbH, Gravitas Biomanufacturing, Hitachi Chemical Advances Therapeutic Solutions, Lonza, MasTHerCell, MEDINET Co., Takara Bio, and XuXi PharmaTech (6, 9, 10).

The top 50 gene therapy start-up companies have attracted more than $11.6 billion in funds in recent years, with the top 10 companies generating US$5.3 billion in series A to D funding rounds (10). US-based Sana Biotechnology leads the field garnering US$700 million to develop scalable manufacturing for genetically engineered cells and its pipeline program, which include CAR-T cell-based therapies in oncology and CNS (Central Nervous System) disorders (11). In second place, Editas Medicine attracted $656.6 million to develop CRISPR nuclease gene editing technologies to develop gene therapies for rare disorders (12).

Overall, CGTs have attracted the pharma industrys attention as they provide an alternative route to target diseases that are poorly served by pharmaceutical and/or medical interventions, such as rare and orphan diseases. Private investors continue to pour money into this sector because a single shot has the potential to bring long-lasting clinical benefits to patients (13). In addition, regulators have approved several products and put in place fast track designation to speed up patient access to these life-saving medicines. Furthermore, healthcare providers have established reimbursement policies and manufacturers have negotiated value- and outcome-based contracts to reduce barriers to access to these premium priced products

On the downside, the manufacture of CGTs is labor intensive and expensive with manufacturing accounting for approximately 25% of operating expenses, plus there is still significant variation in the amount of product produced. On the medical side, many patients may not be suitable candidates for CGTs or not produce durable response due to pre-exposure to the viral vector, poor gene expression, and/or the development of immunogenicity due to pre-exposure to viral vectors. Those that can receive these therapies may suffer infusion site reactions, and unique adverse events such as cytokine release syndrome and neurological problems both of which can be fatal if not treated promptly (14).

Despite the considerable advances that have been made in the CGT field to date, there is still much work needed to enhance the durability of responses, increase biomanufacturing efficiencies and consistency and to implement a seamless supply chain that can ensure these agents are accessible, cost-effective, and a sustainable option to those in need.

Aileron Therapeutics Announces Oral Presentation of Non-Clinical Data Demonstrating ALRN-6924 Protected Human Hair Follicles and Their Stem Cells from…

Posted: October 4, 2022 at 2:09 am

Aileron Therapeutics, Inc.

New ex vivo data demonstrates protection against cyclophosphamide-induced damage to hair follicles and their stem cells

Encore presentation of data presented at Society for Investigative Dermatology in May 2022 shows:

ALRN-6924 temporarily arrested the cell cycle in human scalp hair follicles and their stem cells

Ex vivo data demonstrated protection against taxane-induced damage to hair follicles and their stem cells

Nearly all breast cancer patients receiving neoadjuvant or adjuvant chemotherapy, including cyclophosphamide and taxanes, such as docetaxel, experience alopecia (hair loss)

Aileron is evaluating ALRN-6924 as a novel chemoprotective agent to prevent chemotherapy-induced bone marrow toxicities and alopecia in its ongoing Phase 1b breast cancer trial

BOSTON, Sept. 30, 2022 (GLOBE NEWSWIRE) -- Aileron Therapeutics (Nasdaq: ALRN), a chemoprotection oncology company that aspires to make chemotherapy safer and thereby more effective to save more patients lives, today announced an oral presentation at the European Society for Dermatological Research (ESDR) Annual Meeting, taking place September 28 October 1, 2022 in Amsterdam.

This presentation includes non-clinical data initially presented at the Society for Investigative Dermatology in May 2022 as well as new non-clinical data developed in collaboration with Professor Ralf Paus, M.D., DSc, FRSB and his colleagues at the Dr. Phillip Frost Department of Dermatology & Cutaneous Surgery at the University of Miami Miller School of Medicine.

Details of the presentation are as follows:

Title:

Temporary cell cycle arrest in human scalp hair follicles and their epithelial stem cells by ALRN-6924: A novel strategy to selectively protect p53-wildtype cells against paclitaxel-induced alopecia [Abstract 549]

Presenter:

Dr. Ralf Paus; Paus Laboratory, University of Miami Miller School of Medicine

Date:

Saturday, October 1, 2022

Time:

12:40 12:50 p.m. (local time)

Session:

Concurrent session #9: Photobiology and Pigmentation

Until one is confronted personally with the loss of hair due to chemotherapy, I think its difficult to truly understand just how difficult this side effect can be for patients. It is yet another burden layered on top of their already-daunting fight against cancer, said Dr. Paus. Cold caps, the only FDA-approved treatment for chemotherapy-induced alopecia, are unavailable in many institutions, can cause additional discomfort, and while often quite useful are of unpredictable efficacy in a given individual patient. One also cannot help wondering whether scalp micro-metastases might profit from scalp cooling.

Story continues

Dr. Paus continued, Based on our hair follicle and scalp skin organ culture work with ALRN-6924, testing two of the most hair loss-inducing chemotherapies, paclitaxel and cyclophosphamide, were very encouraged by the potential this drug may hold to prevent alopecia in cancer patients, including for protecting the hair follicle's sensitive stem cell compartment from permanent damage. Were particularly excited by ALRN-6924s highly innovative design, which selectively protects normal cells from the destructive effects of chemotherapy, but in contrast to any other currently available alopecia-protective strategy crucially, not the cancer cells.

Aileron is currently developing ALRN-6924, a first-in-class MDM2/MDMX dual inhibitor, to selectively protect healthy cells in patients with cancers that harbor p53 mutations to reduce or eliminate chemotherapy-induced side effects while preserving chemotherapys attack on cancer cells. The company is conducting a Phase 1b clinical trial of ALRN-6924 in patients with p53-mutated breast cancer undergoing either neoadjuvant or adjuvant treatment with docetaxel, doxorubicin and cyclophosphamide, also known as TAC. Ailerons vision is to bring chemoprotection to all patients with p53-mutated cancer regardless of the type of cancer or chemotherapy.

Manuel Aivado, M.D., Ph.D., President and Chief Executive Officer at Aileron, commented, Were excited about the results generated by Dr. Paus and his colleagues, particularly given their significant and widely recognized expertise in chemotherapy-induced alopecia. We have amassed a body of strong scientific evidence, including the data being presented at the ESDR meeting, which demonstrate ALRN-6924s cell cycle arrest mechanism and support its potential to protect against chemotherapy-induced bone marrow toxicities and other toxicities, including alopecia. Collectively, these nonclinical and clinical data have informed the design of our breast cancer trial. We look forward to our anticipated data readouts from that trial later this year and into 2023.

About the Paus et al. Findings

Taxanes, such as paclitaxel and docetaxel, are known to cause severe and often permanent chemotherapy-induced alopecia. Over 90% of patients treated with this chemotherapy class experience alopecia, and approximately 10% (paclitaxel) to 25% (docetaxel) of patients experience permanent alopecia. Cyclophosphamide is also known to cause alopecia: it is commonly co-administered with doxorubicin (Adriamycin) chemotherapy in the AC combination, with greater than 90% of patients experiencing hair loss.

Dr. Paus and his team previously demonstrated that paclitaxel damages human scalp hair follicles by inducing massive mitotic defects and apoptosis in hair matrix keratinocytes as well as bulge stem cell DNA damage, and that pharmacological induction of transient cell cycle arrest can protect hair follicles and stem cells (Purba et al. EMBO Molecular Medicine 2019). Aileron previously conducted in vitro studies showing that ALRN-6924 protected human fibroblasts in cell culture from multiple chemotherapies, but not p53-mutant breast cancer cells.

In the non-clinical findings presented at the ESDR and SID meetings, when organ-cultured anagen (i.e., active growth phase) scalp hair follicles from human donors were pre-treated with ALRN-6924 or vehicle (i.e., placebo), followed by paclitaxel or vehicle, ALRN-6924 significantly increased the number of p21-positive hair matrix keratinocytes and bulge stem cells compared to vehicle or paclitaxel alone, confirming cell cycle arrest ex vivo. Further, pretreatment of paclitaxel-treated human hair follicles with ALRN-6924, led to a reduction in the number of melanin clumps, a marker of hair follicle cytotoxicity and dystrophy, as well as a reduction in apoptosis, pathological mitosis, and DNA damage. In new data presented at the ESDR meeting, these assays also yielded positive findings for 4-HC (4-hydroperoxy cyclophosphamide), the active metabolite of cyclophosphamide that is formed in vivo and commonly used for in vitro studies. Aileron believes that these findings support clinical investigation of ALRN-6924s ability to prevent both acute and permanent chemotherapy-induced alopecia, in addition to its ongoing evaluation of ALRN-6924s ability to protect against chemotherapy-induced bone marrow and other toxicities.

About Ailerons Breast Cancer Clinical Trial

Aileron is underway with a Phase 1b, open-label, single-arm, multicenter trial designed to evaluate the safety, tolerability and chemoprotective effect of ALRN-6924 in up to 24 patients with p53-mutated breast cancer undergoing either neoadjuvant or adjuvant treatment with docetaxel, doxorubicin and cyclophosphamide, also known as TAC. The primary endpoints are duration and incidence of severe neutropenia (Grade 4) in cycle 1. Secondary endpoints include the chemoprotective effect of ALRN-6924 on chemotherapy-induced alopecia, as well as other hematologic and non-hematologic toxicities. Planned readouts from the breast cancer trial include data from initial patients in the trial in the fourth quarter of 2022; an interim analysis on 12 patients in the second quarter of 2023; and topline results from 20 patients in the third quarter of 2023.

About Aileron Therapeutics

Aileron is a clinical stage chemoprotection oncology company that aspires to make chemotherapy safer and thereby more effective to save more patients lives. ALRN-6924, our first-in-class MDM2/MDMX dual inhibitor, is designed to activate p53, which in turn upregulates p21, a known inhibitor of the cell replication cycle. ALRN-6924 is the only reported chemoprotective agent in clinical development to employ a biomarker strategy, in which we exclusively focus on treating patients with p53-mutated cancers. Our targeted strategy is designed to selectively protect multiple healthy cell types throughout the body from chemotherapy without protecting cancer cells. As a result, healthy cells are spared from chemotherapeutic destruction while chemotherapy continues to kill cancer cells. By reducing or eliminating multiple chemotherapy-induced side effects, ALRN-6924 may improve patients quality of life and help them better tolerate chemotherapy. Enhanced tolerability may result in fewer dose reductions or delays of chemotherapy and the potential for improved efficacy.

Our vision is to bring chemoprotection to all patients with p53-mutated cancers, which represent approximately 50% of cancer patients, regardless of type of cancer or chemotherapy. Visit us at aileronrx.com to learn more.
