Radiopharmaceuticals have long been shown to be effective at killing cancers, but often damage healthy cells because they are so toxic. Convergent Therapeutics has developed platform technology that takes advantage of the power of radiopharmaceuticals, but links them to targeting mechanisms, such as monoclonal antibodies and ligands, to deliver them in a precise and highly targeted ways. Its lead experimental therapy is an actinium-linked monoclonal antibody that targets prostate-specific membrane antigen to treat prostate cancer. The ability to use dual targeting mechanisms offers the potential for powerful combinations of radiopharmaceuticals while limiting their toxicities. We spoke to Philip Kantoff, co-founder and CEO of Convergent, about the company’s platform technology for developing next-generation radiopharmaceuticals, how the company targets tumor surface molecules, and how its approach minimizes the toxicity of these therapies.

Whether it’s capturing the imagination of a venture capitalist, enticing a potential partner, or attracting talent, CEOs need to be able to tell their company’s story effectively. In his new book “Winners Have a Story,” Giuseppe Marzio discusses how CEOs can turn complex science and technology into compelling tales. Marzio, who worked as a scientist in biopharma before launching a communications agency, comes to his interest in storytelling honestly. Growing up with a love for the cinema, he had dreams of becoming a filmmaker and has studied the structure of stories. We spoke to Marzio, founder of the communications agency Chiaro, about his new book “Winners Have a Story,” why a good pitch shares a common structure with novels and movies, and why a company’s strategy and story are inextricably linked.

It’s been understood for more than 60 years that cancer cells overproduce sugars on their surface. More recently it’s been discovered that these sugars can help cancer cells evade the immune system. Palleon Pharmaceuticals is developing immunotherapies that work by targeting these cell surface sugars and make them vulnerable to attack. We spoke to David Feltquate, chief medical officer of Palleon, about the potential to harness glycobiology to treat cancer, how the company is working to modulate cell-surface sugars, and its emerging pipeline of glyco-immuno therapies.

Current treatment of acute myeloid leukemia generally consists of chemotherapy followed by a hematopoietic stem cell transplant to eliminate any remaining cancer cells from the bone marrow. Even though outcomes remain poor with around 40 percent of transplanted patients experiencing cancer relapse, and patients who do relapse having two-year survival rates of less than 20 percent, the approach has changed little in 40 years. One reason is that newly transplanted patients are unable to receive targeted cancer therapies since those therapies would be toxic to the fragile transplanted stem cells. Vor Bio’s solution is to edit the stem cells prior to transplanting them so they lack the receptors targeted therapies attack. We spoke to Robert Ang, president and CEO of Vor Bio, about the company’s platform technology, how it works, and why it has the potential to change outcomes for patients with AML and other hematologic malignancies.

In cancer, the rigorous translational machinery of the human body goes haywire, causing an overproduction of proteins that fuel the growth and spread of tumors, as well as enabling them to evade the immune system. Effector Therapeutics is developing a new class of cancer therapies called selective translation regulator inhibitors, or STRIs, that can inhibit the production of proteins that drive a cancer. We spoke to Steve Worland, president and CEO of Effector, about the company’s new class of therapies, how they target a central node where two major cancer signaling pathways converge, and how they pack the punch of a combination therapy in a single drug.

While cell therapies hold great promise for not only halting the progression of degenerative disease but potentially restoring the body, cost has remained a barrier. Lineage Cell Therapeutics is developing allogenic cell therapies that don’t rely on modifying a patient’s own cells, making them scalable and less costly than autologous ones. At the end of last year, the company entered into a partnership with Genentech to develop and commercialize OpRegen, its experimental cell therapy for dry age-related macular degeneration. We spoke to Brian Culley, CEO of Lineage Cell Therapeutics, about the company’s platform technology for off-the-shelf cell therapies, how its platform works, and what the collaboration with Genentech will do to advance the technology.

A broad range of serious diseases involve chronic inflammation, which causes both pain and progressive damage. Xalud Therapeutics is developing a locally-delivered, non-viral gene therapy that is designed to harness the ability of interleukin-10 to regulate the immune system and restore homeostasis. The company’s lead indication is in osteoarthritis We spoke to Diem Nguyen, CEO of Xalud, about the role inteleukin-10 plays in regulating multiple pathways in the immune system, Xalud’s gene therapy, and the indications the company is pursuing.

Traditional antibody discovery depends, in part, on a bit of good fortune that banks on the hope that either screening antibody libraries or exposing an organism to an antigen will result in the discovery of a compelling therapy. Yanay Ofran, CEO of Biolojic Design, says the problem with this approach is that it ignores many of the performance-related aspects of an antibody beyond its ability to bind to a target. His company’s AI platform for antibody discovery seeks to capitalize on the full capabilities of antibodies to develop smarter therapies that can serve as molecular switches and act conditionally. We spoke to Ofran about Biolojic’s platform technology, how it mimics the way the immune system makes antibodies, and why its approach will lead to smarter therapies.

The rise of antibiotic resistance and the threat of emerging viral pathogens have created global public health threats. Recce Pharmaceuticals is developing a new class of synthetic anti-infectives that it says can overcome the hyper-cellular mutation of bacteria and viruses. What’s more, the company says their potency doesn’t diminish even with repeated use. We spoke to James Graham, CEO of Recce, about its synthetic anti-infectives, how they work, and why they can be used repeatedly against a broad range of bacteria and viruses.

Whether in an operating room or in a trauma situation, the ability to quickly stop bleeding represents a critical need in healthcare. At the end of December, Cresilon filed for U.S. Food and Drug Administration approval to market its hemostatic gel to rapidly stop bleeding. The filing follows the launch of Vitigel, Cresilon’s hemostatic gel for the animal health market. We spoke to Joe Landolina, co-founder and CEO of Cresilon, about how he developed the plant-derived gel, the significant need he is seeking to address, and how the gel is able to halt bleeding in a matter of seconds.
