Asymmetrex Presents New Developments in its Rapid Stem Cell Counting Technology at the ARMI|BioFabUSA Meeting in the Millyard on Regenerative Medicine…

Asymmetrex reports algorithms for rapid quantification of therapeutic stem cells

BOSTON (PRWEB) June 09, 2022

In 2021, stem cell biotechnology company Asymmetrex announced its award of a Technical Project grant from ARMI|BioFabUSA. ARMI assembles, integrates, and leads academic, government, and industry partners in coordinated research and development with a unique vision of accelerating innovation in the biomanufacturing of products and treatments for regenerative medicine. Asymmetric became a member company of ARMI|BioFabUSA less than a year before being selected to evaluate whether its unique tissue stem cell counting technology could be successfully adapted for use in cell and tissue biomanufacturing.

Now, a little over a year later, the company is reporting the results of its evaluation in two presentations in ARMI|BioFabUSAs Spring Meeting in the Millyard R&D summit, scheduled for September 7-9. On the opening morning of the summit on September 7, Asymmetrex presented an interactive Technology Demonstration of the capabilities of the newly automated software for its kinetic stem cell (KSC) counting technology. Automation is one of the four main ARMI|BioFabUSA principles for accelerating biomanufacturing capability. The others are modularity, scalability, and closed operability.

The new software automation provides a tenfold increase in the speed of determinations of changes in the relative fractions for tissue stem cells and their related cell subpopulations during biomanufacturing. No other technology has this capability; and the new software automation allows it to be performed with greater speed and even greater precision.

Asymmetrexs second presentation was a poster displayed at the summits poster session on the evening of September 8. The poster provides a first look at the industry potential of validated rapid-counting algorithms for therapeutic stem cells. The speed and precision achieved by the software automation makes the derivation of these unique biological equations routine. Called Rabbit algorithms for their speed, Asymmetrex is currently developing online calculators for access to their use. The calculators use simple conventional cell count data to determine the specific fraction or dose of the tissue stem cells present in a biomanufacturing or treatment sample.

The facility and speed of the rapid stem cell counting algorithms enable straightforward integration of KSC counting for monitoring therapeutic stem cells in cell and tissue biomanufacturing processes. Asymmetrex is now designing a pilot online rapid-counting beta-test with ARMI|BioFabUSA bioengineers who collaborated in the research. Asymmetrex founder, James L. Sherley, M.D., Ph.D., expresses the companys excitement with the new advances, Determining the dose of therapeutic stem cells is now more than just possible for the first time. With ARMIs support it's getting easy to do, too!

UB-led study presents critical step forward in understanding Parkinson’s disease and how to treat it – University at Buffalo

BUFFALO, N.Y. A new study led by a researcher in the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo has important implications for developing future treatments for Parkinsons disease (PD), a progressive nervous system disorder that affects movement and often includes tremors.

In this study, we find a method to differentiate human induced pluripotent stem cells (iPSCs) to A9 dopamine neurons (A9 DA), which are lost in Parkinsons disease, says Jian Feng, PhD, professor of physiology and biophysics in the Jacobs School and the senior author on the paper published May 24 in Molecular Psychiatry.

These neurons are pacemakers that continuously fire action potentials regardless of excitatory inputs from other neurons, he adds. Their pacemaking property is very important to their function and underlies their vulnerability in Parkinsons disease.

This exciting breakthrough is a critical step forward in efforts to better understand Parkinsons disease and how to treat it, says Allison Brashear, MD, UBs vice president for health sciences and dean of the Jacobs School. Jian Feng and his team are to be commended for their innovation and resolve.

Feng explains there are many different types of dopamine neurons in the human brain, and each type is responsible for different brain functions.

Nigral dopamine neurons, also known as the A9 DA neurons, are responsible for controlling voluntary movements. The loss of these neurons causes the movement symptoms of Parkinsons disease, he says.

Scientists have been trying hard to generate these neurons from human pluripotent stem cells to study Parkinsons disease and develop better therapies, Feng says. We have succeeded in making A9 dopamine neurons from human induced pluripotent stem cells. It means that we can now generate these neurons from any PD patients to study their disease.

Feng notes that A9 DA neurons are probably the largest cells in the human body. Their volume is about four times the volume of a mature human egg.

Over 99 percent of the volume is contributed by their extremely extensive axon branches. The total length of axon branches of a single A9 DA neuron is about 4.5 meters, he says. The cell is like the water supply system in a city, with a relatively small plant and hundreds of miles of water pipes going to each building.

In addition to their unique morphology, the A9 DA neurons are pacemakers they fire action potentials continuously regardless of synaptic input.

They depend on Ca2+ channels to maintain the pacemaking activities. Thus, the cells need to deal with a lot of stress from handling Ca2+ and dopamine, Feng says. These unique features of A9 DA neurons make them vulnerable. Lots of efforts are being directed at understanding these vulnerabilities, with the hope of finding a way to arrest or prevent their loss in Parkinsons disease.

Pacemaking is an important feature and vulnerability of A9 DA neurons. Now that we can generate A9 DA pacemakers from any patient, it is possible to use these neurons to screen for compounds that may protect their loss in PD, Feng notes. It is also possible to test whether these cells are a better candidate for transplantation therapy of PD.

To differentiate human iPSCs to A9 DA neurons, the researchers tried to mimic what happens in embryonic development, in which the cells secrete proteins called morphogens to signal to each other their correct position and destiny in the embryo.

Feng notes the A9 DA neurons are in the ventral part of the midbrain in development.

Thus, we differentiate the human iPSCs in three stages, each with different chemicals to mimic the developmental process, he says. The challenge is to identify the correct concentration, duration, and treatment window of each chemical.

The combination of this painstaking work, which is based on previous work by many others in the field, makes it possible for us to generate A9 DA neurons, Feng adds.

Feng points out there are a number of roadblocks to studying Parkinsons disease, but that significant progress is being made.

There is no objective diagnostic test of Parkinsons disease, and when PD is diagnosed by clinical symptoms, it is already too late. The loss of nigral DA neurons has already been going on for at least a decade, he says.

There was previously no way to make human dopamine neurons from a PD patient so we could study these neurons to find out what goes wrong.

Scientists have been using animal models and human cell lines to study Parkinsons disease, but these systems are inadequate in their ability to reflect the situation in human nigral DA neurons, Feng says.

Just within the past 15 years, PD research has been transformed by the ability to make patient-specific dopamine neurons that are increasingly similar to their counterparts in the brain of a PD patient.

Houbo Jiang, PhD, research scientist in the Department of Physiology and Biophysics, and Hong Li, PhD, a former postdoctoral associate in the Department of Physiology and Biophysics, are co first-authors on the paper.

Other co-authors on the study are: Hanqin Li, PhD, a graduate of the doctoral program in neuroscience and currently a postdoctoral fellow at University of California, Berkeley; Li Li, a trainee in UBs doctoral program in neuroscience; and Zhen Yan, PhD, SUNY Distinguished Professor of physiology and biophysics.

The study was funded by the Department of Veterans Affairs, National Institutes of Health and by New York State Stem Cell Science (NYSTEM).

Protein discovery reinvigorates promising new therapeutic – EurekAlert

Several years ago, a promising therapeutic using stem cell factor (SCF) emerged that could potentially treat a variety of ailments, such as ischemia, heart attack, stroke and radiation exposure. However, during clinical trials, numerous patients suffered severe allergic reactions and development of SCF-based therapeutics stopped.

A research team led by engineers at The University of Texas at Austin has developed a related therapeutic that they say avoids these major allergic reactions while maintaining its therapeutic activity. The keys to the discovery, published recently inNature Communications, were the use of a similar, membrane-bound version of SCF delivered in engineered lipid nanocarriers.

"We envision this as something you can inject where you have lack of blood flow and it could induce blood vessels to grow in that area," said Aaron Baker, a professor in the Cockrell School of Engineering's Department of Biomedical Engineering, and one of the leaders on the project.

Stem cell factor is a cytokine, a type of soluble protein that can stimulate regeneration in the body and growth of stem cells. Its ability to help stem cells grow, especially in critical places like bone marrow, makes it very promising for many therapeutic applications. But when delivered to the body in clinical trials related to strokes, it caused mast cell growth, which activated the immune systems defenses and led to the allergic reactions.

The new therapeutic uses transmembrane stem cell factor, a version of the cytokine that tethered to a cell membrane. In the body, the transmembrane form can be cleaved off into to the soluble form, which travels around the body.

"We found this transmembrane stem cell factor has all the necessary therapeutic properties and without activating the immune system and causing allergic reaction," said Eri Takematsu, a former member of Bakers lab who is now a postdoctoral researcher at Stanford and was the first author on the paper.

The big problem with the transmembrane SCF is that, because its not soluble, it tends to just clump together in solution. So, the team developed lipid nanocarriers to help it say in solution and to tailor its activity towards different cell type. They looked specifically at using a liposomes (lipid bubbles) and lipid nanodiscs as carriers for transmembrane SCF.

"This type of nanodisc is something people haven't explored very much developing therapeutics before," Baker said. "It makes a little island of lipid around the transmembrane SCand holds it together with a ring of proteins, kind of like a lariat."

The researchers have patented their method, and the next step would be clinical trials. In order to do that, however, they need approval from the U.S. Food and Drug Administration to classify the therapeutic as aninvestigational new drug. In addition, they are continuing to fine-tune important details like correct dosage for patients.

Other team members on the project include Miles Massidda, Jeff Auster, Po-Chih Chen, ByungGee Im, Sanjana Srinath, Sophia Canga, Aditya Singh, Marjan Majid and Andrew Dunn from the Department of Biomedical Engineering; Michael Sherman from the Department of Biochemistry & Molecular Biology, University of Texas Medical Branch, Galveston; and Annette Graham and Patricia Martin of the Department of Biological and Biomedical Sciences at Glasgow Caledonian University in Scotland. The research was funded through grants from the American Heart Association, National Institutes of Health and the U.S. Department of Defense's Congressionally Directed Medical Research Programs.

- Combined company Senti Bio will be listed on the Nasdaq Global Market under ticker symbol "SNTI" -

- IND filings for preclinical oncology candidates SENTI-202 and SENTI-301 anticipated in 2023 -

SOUTH SAN FRANCISCO, Calif., June 09, 2022 (GLOBE NEWSWIRE) -- Senti Biosciences, Inc. (Senti Bio), a biotechnology company developing next-generation cell and gene therapies using its proprietary gene circuit platform, today announced the completion of its business combination with Dynamics Special Purpose Corp. (DYNS; Nasdaq: DYNS), a special purpose acquisition company. Senti Biosciences, Inc., the resulting combined company, will commence trading on the Nasdaq Global Market under the symbol SNTI on June 9, 2022.

Over the last year, we have made significant pipeline progress in optimizing our gene circuit technology and generating promising data across our lead programs, SENTI-202 and SENTI-301, which we plan to advance toward IND filings in 2023, said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. We believe that with the funding from this successful transaction, we are well positioned to maximize this unique opportunity to develop the next generation of gene circuit-enabled cell and gene therapies for patients in need.

Senti Bio is developing next-generation cell and gene therapies engineered with gene circuits, which are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. Senti Bio's oncology pipeline uses healthy adult donor-derived, natural killer (NK) cells engineered with chimeric antigen receptor (CAR) gene circuits that are cryopreserved and dosed off-the-shelf. Senti Bios oncology pipeline is primarily focused on three preclinical-stage programs: SENTI-202, a Logic Gated (OR+NOT) off-the-shelf CAR-NK cell therapy designed to target and eliminate acute myeloid leukemia (AML) cells while sparing the healthy bone marrow; SENTI-301, a regulatable Multi-Armed off-the-shelf CAR-NK cell therapy designed for the treatment of hepatocellular carcinoma (HCC); and SENTI-401, a Logic Gated (NOT) off-the-shelf CAR-NK cell therapy designed to target and eliminate colorectal cancer (CRC) cells while sparing healthy cells elsewhere in the body. In addition, the company is collaborating with Spark Therapeutics (a member of the Roche Group) and BlueRock Therapeutics (a wholly-owned and independently operated subsidiary of Bayer AG) on applications of its gene circuit technology outside of oncology.

Omid Farokhzad, MD, Executive Chair of the DYNS Board of Directors, said, We believe in the powerful potential of engineering gene circuits with programmable computer-like logic in cell and gene therapies. We look forward to continued progress from the Senti Bio team including advancing product candidates towards and into clinical trials, solidifying its clinical-scale cGMP manufacturing capabilities, and expanding its gene circuit offerings across multiple diseases and modalities via partnering opportunities.

Mostafa Ronaghi, PhD, CEO of DYNS added, We have been very impressed with Sentis approach and platform, which has the potential to define the future of cell and gene therapy. Sentis scientific founders and management are pioneers in the field of mammalian synthetic biology and have assembled a highly qualified team to use this platform to improve the lives of patients in oncology and many other disease categories.

Senti Bio received gross proceeds of approximately $140.3 million of the expected $156.5 million in connection with the business combination, which included funds held in DYNS's trust account of $84.5 million (net of redemptions), $50.6 million of the expected $66.8 million in proceeds from a private investment in public equity (PIPE) financing that closed concurrently with the consummation of the business combination, and a recent $5.2 million investment by Leaps by Bayer, the impact investment arm of Bayer AG, through the purchase of a convertible note that was exchanged (at $10.00 per share, with accrued interest canceled) at the closing of the business combination for common equity with the same rights as the PIPE shares. Senti Bio expects the proceeds from this transaction, combined with cash on hand, to fund operations into 2024.

Investors in DYNS include funds managed by ARK Investment Management LLC, funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), Invus, and funds and accounts advised by T. Rowe Price Associates, Inc., among others.

Investors participating in the PIPE financing as of the closing of the business combination included 8VC, Amgen Ventures, funds and accounts managed by Counterpoint Global (Morgan Stanley Investment Management), Invus, NEA, Parker Institute for Cancer Immunotherapy, and T. Rowe Price funds, among others. Of the $66.8 million in subscriptions for the PIPE financing, $16.2 million has yet to be funded as one investor, who entered into a subscription agreement concurrently with Senti Bio and DYNSs execution of the business combination agreement in December 2021, has not funded its commitment. Senti Bio intends to enforce such one investor's legal obligations under its subscription agreement. Solely for purposes of consummating the business combination on June 8, 2022, Senti Bio agreed to waive the $150 million available cash closing condition under the business combination agreement previously entered into with DYNS (as a result of such one investor failing to timely fund its $16.2 million commitment).

DYNSs board members, Dr. Omid Farokhzad and David Epstein, have joined the Senti Bio Board of Directors. The other Senti Bio board members are Susan Berland, Dr. James Collins, Dr. Brenda Cooperstone, Dr. Timothy Lu and Edward Mathers.

Uses of Proceeds and Planned Milestones Proceeds from the transaction are expected to provide Senti Bio with capital to further develop its gene circuit technologies and therapeutic pipeline, including:

CMC Joint Arthroplasty at Bone and Joint Institute of Tennessee Successfully Treats Advanced Thumb Joint Arthritis When Other Treatments Fail -…

The development of an opposable thumb in mankind is what has moved us beyond other animals, allowing us to make tools, eat more meat, and evolve a bigger brain. About seven million years ago, we grew a long thumb and shorter fingers allowing us to touch our thumbs to our other fingers. This is why our ancestors were able to throw a spear to kill wild game and hold a writing implement to record our history. However, because we use the thumb joint so much, thumb carpometacarpal (CMC) osteoarthritis is quite common. It affects up to 11% of men and 33% of women in their 50s and 60s. However, in the mid-1980s a successful surgical procedure was developed to return movement to the joint and relieve pain.

Todd Wurth, M.D. performs more than 100 of these surgeries every year, and has been recognized by the Nashville Business Journal many times as one of Nashvilles Best Hand Surgeons. He is a board-certified orthopaedic surgeon specializing in treatment of the shoulder, elbow, hand and wrist. He earned his medical degree in 1998 from the University of Louisville School of Medicine, completed his residency in orthopaedic surgery at the Indiana University Medical Center, then completed fellowship training at Allegheny General Hospital in Pittsburgh in the areas of hand, wrist, elbow, shoulder and microvascular surgery. He is a fellow in the American Academy of Orthopaedic Surgeons and a member of the American Society for Surgery of the Hand with a certificate of added qualifications in surgery of the hand.

Williamson Source: You do a lot of thumb carpometacarpal (CMC) arthroplasties every year. Tell us a little about the surgery?

Dr. Todd Wurth: CMC arthroplasty is a procedure that removes the damaged, arthritic trapezium bone at the base of the thumb and utilizes a tendon that is transferred from the forearm to stabilize the thumb in the absence of the trapezium. This is an exceptionally important joint, one that allows us to have an opposable thumb. The pain and dysfunction resulting from arthritis in the thumb CMC joint can have a huge impact on peoples lives.

There are many ways to complete this operation. A number of companies have developed implants to take the place of the damaged bone, but I prefer the use of my patients own tendon to stabilize the thumb and act as a soft tissue interposition rather than relying on manufactured implants that often only address one side of the arthritic joint and present a whole host of potential complications that are avoidable. I have seen the new technology in this area fail. The original description of this surgery was proposed in 1985 and has undergone some modifications since, but the original premise remains the same and is time tested. I value the idea of surgical procedures that use biologic rather than non-biologic materials to treat a condition when feasible. The biologic options typically outlast those of non-biologics and have lower rates of long-term complications.

After removing the damaged trapezium bone, I transfer a forearm tendon to create a sling that stabilizes the thumb in the absence of the removed trapezium. This transferred tendon actually reconstructs a ligament whose sole purpose is to stabilize the thumb. It is laxity within this original ligament that actually results in the arthritis to begin with. I then use the rest of the tendon to act as a soft tissue interposition to occupy the space of the removed trapezium.

The key to this surgery is stability of the thumb. Some surgeons simply remove the trapezium, which provides relief of the arthritic joint, but fails to stabilize the thumb. Studies have demonstrated similar outcomes to simple bone removal without tendon transfer to those of bone removal with tendon transfer at 1-3 years. Beyond three years, thumbs stabilized with tendon transfer outperformed and outlasted those without tendon transfer. My goal as a surgeon is to provide my patients with the best opportunity for long-lasting success.

WS: What is recovery time? What happens during recovery?

Dr. Wurth: Immediately after surgery the patient is put into a splint that immobilizes the thumb, wrist, and mid-forearm for five days. It is non-removable and must remain dry. After five days, the original splint is removed and replaced with a custom, removable splint that, like the original splint, goes up to the mid-forearm. This is worn day and night for about three weeks, removing it for bathing and wrist range of motion exercises. The fingers are not incorporated and we recommend aggressive finger range of motion from the start. We have patients refrain from heavy lifting and pinching activities, and because of this they may require assistance around the house for a period of time following surgery.

After three weeks in this splint, we cut the splint down to the hand only. This splint only immobilizes the thumb and leaves the wrist free when wearing. This splint is removed several times daily to work on the thumb range of motion including opposing to the other fingers. This splint is worn for approximately two weeks.

Finally, the splint is replaced with a neoprene sleeve. I encourage my patients to refrain from heavy gripping and pinching activities for a period of three months after surgery. At three months, I cut them loose to increase their activities as tolerated and return to all activities. Full return to certain activities can take up to six months.

WS: I know surgery is always a last resort, so what are non-surgical treatments?

Dr. Wurth: There are oral and topical anti-inflammatory medications that help relieve the pain. Over-the-counter versions would be things like Aleve, Motrin, Voltaren Gel or Icy Hot, but there are also prescription strength medications. Splinting is another option which works by adding additional stability to the thumb. Cortisone injections are also an option for temporary relief, but should be used judiciously. More than two a year may actually exacerbate the arthritic process.

WS: Is there any new technology being used to relieve the pain and damage of CMC arthritis?

Dr. Wurth: Work is being done on stem cell injections, but I would suggest holding off on this treatment until more research has been implemented. True stem cell lines are currently limited to research facilities. Facilities offering stem cell treatment in the community typically lack the quality and quantity of stem cell lineage to offer meaningful results. I have expectations that someday we may be able to use stem cell treatment to regenerate cartilage, but we are not there yet.

WS: As we age, we all get aches and pains? When will a patient know it is time to see you about the pain in their thumb?

Dr. Wurth: My recommendation to patients has always been that when their ailments, in this case basilar thumb pain, begin to affect what they need to do or what they want to do on a daily basis, then its time to come see me to discuss options for alleviating their symptoms.

If a patient has had a previous CMC surgery that is no longer relieving their pain, like those done with implants, they can be re-evaluated for revision surgery.

WS: Can anything be done to prevent thumb arthritis?

Dr. Wurth: Thumb arthritis is typically caused by a lack of stability in the CMC joint. Genetics plays a big role and women are more prone to it than men by a ratio of 7:1.

While some jobs are harder on the thumb joint than others, supporting the joint with a splint and changing thumb usage to minimize the strain that exacerbates laxity are ways to lessen the chance of developing arthritis or slowing its progress.

"I saw a gap in how we handle the data coming from the field and how that can impact the fan and nobody was getting it right," Pracht, co-founder and CEO of nVenue, tells InnovationMap. "I saw technologists coming up with the most nonsensical solutions. For fans like me, coming from my crazy sports family from West Texas where my dad was a coach, I knew that these solutions were a huge miss."

She gives the example of a wearable technology for the viewer at home that can feel what it feels like for the players on the field who get hit. Pracht says it seems like companies were trying to fit technology into the sport, rather than thinking of what the fans really wanted.

She had the idea for a data-driven fan tool in 2017 and nVenue was born. She started building out the code and the team started testing it out at Astros games at Minute Maid.

"What great years to develop this platform. It was fun these were not boring baseball games," Pracht says. The Astros have won their division four out of the past five years, including winning the World Series in 2017.

At first, nVenue was using historical data, and that in itself was impressive. But then, Pracht and her team decided to take it live. After building its proprietary analytics platform, nVenue could use data to make predictions in real time.

"We spent over a year all of 2019 mastering timing and putting it into a platform," Pracht says, explaining how they built out the artificial intelligence and designed an app for fans to interface with. "We wanted to be able to predict and play. We had over 180 people during the 2019 World Series and playoffs."

The app and algorithm were good and nVenue expanded into football. Then, the pandemic hit and sports halted completely. Pracht says they pivoted to a B2B model but wasn't seeing any real opportunities for the platform until the 2021 Comcast NBCUniversal SportsTech Accelerator.

"In kind of a last-ditch effort, we applied to the NBC Comcast accelerator somewhere around August or September of 2020," Pracht says, explaining that she wasn't seeing a sustainable business so it was get into the program or close up shop. "And we got in. They just resonated with everything we said we found our people."

The accelerator gave nVenue the jumpstart it needed, and as sports returned, the company found its momentum again. Now, the company is headquartered in Dallas with 14 employees all over and three including Pracht in Houston. The company has raised its $3.5 million seed round co-led by KB Partners and Corazon Capital and plans to raise a Series A next year.

After a few broadcasts last season, opportunity came knocking by way of Apple TV and Houston-based TV Graphics. The companies collaborated on a deal and, two weeks before the 2022 season started, nVenue got the greenlight to have onscreen analytics on Apple TV broadcasts.

"In under two weeks we structured the deal, convinced them it worked, pulled together every bit of testing we could by then we only had one week of pre-season games to test and we pulled it off," Pracht says.

The technology has tons of potential when it comes to sports betting, which is a growing business across the country. Pracht says nVenue isn't looking to compete with the providers on the scene, but instead work with them as an analytics tool.

"We broke down the market down to microbets or in-the-moment bets that are going to happen annually by 2025 it's 156 billion microbets a year, which turns out to be 3 billion a week," Pracht says.

She adds that new technologies in the streaming world like no-delay, latency streaming is only going to make the sports betting world more lucrative, and nVenue will be right there to ride that wave.

Report Highlights

Heart Failure Emerging Drugs

Tirzepatide: Eli Lilly and Company

Tirzepatide is a once-weekly dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist that integrates the actions of both incretins into a single novel molecule. GIP is a hormone that may complement the effects of GLP-1. In preclinical models, GIP has been shown to decrease food intake and increase energy expenditure therefore resulting in weight reductions, and when combined with a GLP-1 receptor agonist, may result in greater effects on glucose and body weight. Tirzepatide is in phase 3 development for chronic weight management and heart failure with preserved ejection fraction (HFpEF). It is also being studied as a potential treatment for non-alcoholic steatohepatitis (NASH). Both the FDA and EMA have accepted Eli Lilly's marketing approval applications for its type 2 diabetes treatment, tirzepatide.

Finerenone (BAY94-8862): Bayer

Finerenone (BAY 94-8862) is an investigational novel, non-steroidal, selective mineralocorticoid receptor antagonist (MRA) that has been shown to block the harmful effects of the overactivated mineralocorticoid receptor (MR) system. MR overactivation is a major driver of heart and kidney damage. Current steroidal MRAs on the market have proven to be effective in reducing cardiovascular mortality in patients suffering from heart failure with reduced ejection fraction (HFrEF). However, they are often underutilized due to the incidence of hyperkalemia, renal dysfunction, and anti-androgenic/ progestogenic side effects.

CardiAMP Cell Therapy: BioCardia

CardiAMP Cell Therapy uses a patient's own (autologous) bone marrow cells delivered to the heart in a minimally invasive, catheter-based procedure to potentially stimulate the body's natural healing response. The CardiAMP Cell Therapy Heart Failure Trial is the first multicenter clinical trial of an autologous cell therapy to prospectively screen for cell therapeutic potency in order to improve patient outcomes. CardiAMP Cell Therapy incorporates three proprietary elements not previously utilized in investigational cardiac cell therapy, which the company believes improves the probability of success of the treatment: a pre-procedural diagnostic for patient selection, a high target dosage of cells, and a proprietary delivery system that has been shown to be safer than other intramyocardial delivery systems and more successful for enhancing cell retention.

Rexlemestrocel-L (Revascor): Mesoblast

Revascor consists of 150 million mesenchymal precursor cells (MPCs) administered by direct injection into the heart muscle in patients suffering from CHF and progressive loss of heart function. MPCs release a range of factors when triggered by specific receptor-ligand interactions within damaged tissue. Based on preclinical data, it is believed that these factors induce functional cardiac recovery by simultaneous activation of multiple pathways, including induction of endogenous vascular network formation, reduction in harmful inflammation, reduction in cardiac scarring and fibrosis, and regeneration of heart muscle through activation of tissue precursors.

BMS-986231: Bristol-Myers Squibb

Cimlanod (development codes CXL-1427 and BMS-986231) is an experimental drug for the treatment of acute decompensated heart failure. HNO gas (nitroxyl) is a chemical sibling of nitric oxide. Although nitric oxide and HNO appear to be closely related chemically, the physiological effects and biologic mechanisms of HNO and nitric oxide action are distinct. The biologic effects of HNO are mediated by direct post-translational modification of thiol residues in target proteins, including SERCA2a, phospholamban, the ryanodine receptor, and myofilament proteins in cardiomyocytes. In vitro, HNO increases the efficiency of calcium cycling and improves myofilament calcium sensitivity, which enhances myocardial contraction and relaxation. HNO also mediates peripheral vasodilation through endothelial soluble guanylate cyclase. HNO does not induce tachyphylaxis in peripheral vessels, unlike nitric oxide.

Elamipretide: Stealth BioTherapeutics

Elamipretide (MTP-131, Bendavia) is a novel tetra-peptide that targets mitochondrial dysfunction in energydepleted myocytes. Elamipretide crosses the outer membrane of the mitochondria and associates itself with cardiolipin, which is a phospholipid expressed only in the inner membrane of mitochondria. Cardiolipin has an integral role in mitochondrial stability and organization of respiratory complexes into super complexes for oxidative phosphorylation.Thus, elamipretide helps to enhance ATP synthesis in multiple organs of the body. Elamipretide has been shown to improve left ventricular ejection fraction (LVEF), LV end diastolic pressure, cardiac hypertrophy, myocardial fibrosis, and myocardial ATP synthesis in both animal models and humans.

FA relaxin: Bristol Myers Squibb

BMS-986259 is a next-generation version of Relaxin that is enabled with our technology and currently in Phase 1 clinical trials for ADHF. Relaxin, a peptide hormone, has been reported to reduce fibrosis in the multiple organs and to exert cardioprotective effects in preclinical studies. However, the therapeutic potential of Relaxin has been partially limited by its short half-life in humans. BMS-986259 has exhibited a prolonged half-life and therefore has the potential to enhance clinical benefit as a novel therapeutic for ADHF.
