The Bio Report

As the treatment of cancers has moved toward an increasing emphasis on the role the immune system can play in fighting tumors, a range of new ways to enlist and train the immune system have emerged. Candel Therapeutics is developing oncolytic viral immunotherapies, which it says combines anti-tumor activity while also stimulating the immune system. We spoke to Paul Peter Tak, president and CEO of Candel Therapeutics, oncolytic viral immunotherapies, how they work, and why they may be able to bring benefits to the treatment of a range of solid tumors.

The discovery and cell line development of biotherapeutics has been traditionally a distinct process. Absci is taking what it describes as a more wholistic approach by collapsing the process down and addressing the functionality and manufacturability of therapeutic candidates simultaneously. We spoke to Sean McClain, founder and CEO of AbSci, about how it is using AI and synthetic biology to reinvent the discovery process, how this is expanding the therapeutic potential of proteins, and how it translates into time and cost benefits.

While CAR-T cell therapies have been a promising new area of cancer treatments, they are costly to produce, have had limited success in treating solid tumors, and can carry sometimes serious side effects. Shoreline Biosciences is developing off-the-shelf natural killer and macrophage cellular immunotherapies derived from induced pluripotent stem cells for cancer, inflammatory, and genetic diseases. The company programs these cells to target and kill tumors, as well as repair tissue homeostasis. The company said its approach allows for the creation of a streamlined, affordable, and scalable manufacturing process that can deliver cell therapy treatments to patients in a faster and more cost-effective manner. We spoke to Kleanthis Xanthopoulos, co-founder and CEO of Shoreline Biosciences, about the company’s off-the-shelf cell therapies, its focus on the innate immune system, and how it’s leveraging its technology through recent partnerships with BeiGene and Kite Pharma.

The ability to discover new drugs can be limited by the tools and technologies small companies can access. Alloy Therapeutics says it democratizing access to a set of technologies and capabilities that are foundational for discovering and developing biologics. We spoke to Errik Anderson, CEO of Alloy Therapeutics, discusses the challenges of drug discovery the company is seeking to address, its business model, and the dealmaking it has done to build beyond platform technologies to become involved in the discovery and development of therapeutic candidates.

One of the consequences of the proliferation of genetic sequencing has been a shortage of genetic counselors. It’s left existing counselors to manage a heavy load as its increased the demands on onboarding patients, consenting them, educating them and interpreting results. The digital health company Igentify is helping providers and genetic counselors scale their services with its AI-based platform that extends through the entire genetic testing process. We spoke to Doron Behar, co-founder and CEO of Igentify, about its platform technology, how it works, and why it will allow genetic counselors to handle a much larger volume of patients.

While CAR-T cell therapies have emerged as promising anti-cancer agents, their success have been focused on hematologic cancers. ArsenalBio is working to develop more robust cell therapies capable to treating a broader range of cancers by using synthetic biology to make them programable. We spoke to Ken Drazen, CEO of ArsenalBio, about the company’s next-generation T cell therapies, how it is able to program functions into these cells to overcome solid tumor defenses, and the company’s collaboration with Bristol-Myers Squibb announced at the start of the year.

Liquid biopsies have become associated with the area of oncology as they hold the promise of using fragments of DNA circulating in the blood that have been shed by tumors to provide early indications of recurrence and customize treatment strategies. The same approach, though, can be used for infectious diseases. Karius has developed a liquid biopsy test to provide rapid and non-invasive detections of more than 1000 pathogens from a single blood draw. The Karius test helps clinicians avoid invasive, low-yield, and sequential diagnostic tests that can delay treatment for the most vulnerable hospitalized patients. We spoke to Alec Ford, CEO of Karius, about the company’s liquid biopsy test, how it works, and how it can change the treatment of immunocompromised patients.

The World Health Organization estimates that 270 million people worldwide suffer from chronic hepatitis B virus infections, making it a global epidemic that affects more than twice the number of people with hepatitis C and HIV combined. HBV is a leading cause of chronic liver disease and the need for liver transplantation, with up to 1 million people worldwide dying from HBV-related causes each year. While current treatments reduce the viral load, they don’t eliminate it. Assembly Bio is developing a pipeline of therapies aimed at curing HBV. We spoke to John McHutchison, president and CEO of Assembly Bio, about HBV, the company’s efforts to develop a new class of drugs to treat the condition, and what he’s learned from his work at Gilead successfully developing and commercializing therapies for HCV. A note to listeners: As we were publishing this episode Assembly Bio announced plans to discontinue development of its phase 2 candidate ABI-H2158 because safety concerns. The company said it will focus on advancing ongoing triple combination studies and earlier pipeline candidates.

Psychedelics have become an area of increasing investment and drug development activities as an emerging group of companies is working to develop these compounds as treatments for neurologic and psychiatric conditions. That’s because of the ability of these drugs to target serotonin, which plays a critical role in the regulation of cognitive function, emotions, memory, and the sleep-wake cycle. Bright Minds Biosciences is developing a pipeline of psychedelics as the next generation of serotonin modulators to treat neuropsychiatric, seizure, and pain disorders by restoring serotonin activity to normal levels. We spoke to Gideon Shapiro, vice president of discovery at Bright Minds Biosciences, about the role serotonin plays in the health of the brain, why psychedelics have emerged as compelling therapeutics for a range of conditions, and the company’s pipeline of drugs in development.

Type 2 diabetes affects nearly 500 million people worldwide and more than 34 million people in the United States. The disease carries an elevated risks of heart attack, stroke, and other serious complications. Fractyl Health believes the approach to treating diabetes by controlling blood sugar levels and other symptoms has been faulty. Research has implicated a critical role the first section of intestine, known as the duodenum, plays in the condition and the company has developed a minimally invasive endoscopic procedure that it believes can correct the problem. We spoke to Harith Rajagopalan, CEO of Fractyl Health, about the company’s experimental procedural therapy to target the root cause of diabetes, how it works, and the path forward to commercialization.
