Engaging Hard-to-Target Receptors with Antibodies that Activate

Antibodies have been powerful tools for inhibiting a targeted protein. Abalone Bio is pursuing a new class of antibody therapies called activating antibodies that can regulate cellular processes and restore their balance. One aspect that makes these rare antibodies attractive is that they can target previously undruggable G protein-coupled receptors, allowing them to treat diseases that have been hard to address. We spoke to Richard Yu, co-founder and CEO of Abalone Bio, about activating antibodies, how the company generates massive data sets for its AI-driven platform technology, and how it looks beyond binding to explore the function of these antibodies.

An Insider’s View of the Patent Fights that Shaped the Biotech Industry

Jorge Goldstein trained for a career in molecular biology and biochemistry before becoming a patent attorney, a background that positioned him to help shape patent law for the biotech industry throughout his 40-year career. In his new book Patenting Life: Tales from the Front Lines of Intellectual Property and the New Biology, Goldstein offers a history of the biotech industry through the lens of the critical patent battles that shaped the landscape. We spoke to Goldstein, founder of the law firm Sterne, Kessler, Goldstein & Fox, about the industry’s critical patent battles, his new book, and how he is working today to use patents as instruments for social and economic justice.

Restoring Balance to the Immune System in Allergic Diseases

Eosinophilic esophagitis is a progressive allergic disease characterized by difficulty swallowing and gastric reflux. It results from an elevated number of inflammatory immune cells in the walls of the esophagus. If left untreated, it can cause long-term complications, including scarring and difficulty swallowing. Revolo Biotherapeutics is developing a synthetic peptide therapy that can potentially restore immune system homeostasis in EOE and other allergic diseases. We spoke to Woody Bryan, president and CEO of Revolo, about eosinophilic esophagitis, how the company’s experimental therapy restores homeostasis to the immune system, and how people exposed to tuberculosis pointed the way toward the experimental therapy.

Turning Natural Killers into Off-the-Shelf Therapies for Autoimmune Disease

NK cells, part of the innate immune system, serve as the body’s first line of defense. These cells can recognize and kill abnormal or infected cells. As therapies, they have the advantage over CAR-T and other cell therapies because they can be used off-the-shelf without undergoing gene editing or other genetic modifications. They also don’t trigger cytokine storms, a common reaction to CAR-T therapies that can cause a systemic inflammatory response that can range from flu-like symptoms to life-threatening complications. The greater safety and lower costs of these NK cell therapies open the door to broader uses beyond cancer to include autoimmune diseases. We spoke to Fred Aslan, president and CEO of Artiva Biotherapeutics, about the company’s off-the-shelf NK cell therapies, the case for pairing them with monoclonal antibodies, and how they can broaden the uses for cell therapies.

Combining an Antibody and siRNA to Treat Hepatitis B

More than a decade after the approval of a curative therapy for hepatitis C, hepatitis B has proven more challenging to tackle. Vir Biotechnology, in collaboration with Alnylam Pharmaceuticals, is developing a promising combination approach that marries Vir’s monoclonal antibody tobivibart with Alnylam’s siRNA elebsiran. We spoke to Mark Eisner, chief medical officer of Vir, about hepatitis B, the company’s combination therapy in development with Alnylam, and its platform technologies for developing treatments for infectious disease and oncology.

Looking at the Promise of GLP-1 Agonists Beyond Obesity

While GLP-1 agonists have been all the rage in treating obesity, Coya Therapeutics sees potential for these therapies to address inflammatory diseases. In fact, Coya is developing its low-dose interleukin 2 in combination with several different agents. The belief is that its approach will address inflammation by targeting dysfunctional regulatory T cells. The company is pursuing multiple neurodegenerative conditions, as well as autoimmune and metabolic diseases. We spoke to Arun Swaminathan, CEO of Coya Therapeutics, about its pipeline-in-a-product strategy to treat neurodegenerative and other inflammatory diseases, its pursuit of a GLP-1 combination therapy for these conditions, and the challenges of being a newly minted public company in the current financial environment.

An Off-the-Shelf Cancer Vaccine Faces a Final Clinical Hurdle in NSCLC

Though cancer vaccines have been an area of great promise, in practice they have faced several challenges because of the heterogeneity of tumors, the ability of the tumor microenvironment to suppress the immune system, and the challenges of producing a strong and sustained T-cell response. OSE Immunotherapeutics’ off-the-shelf cancer vaccine Tedopi has shown promising results in a phase 3 study in patients with non-small cell lung cancer and the company is now conducting a confirmatory phase 3 study. We spoke to Nicolas Poirier, CEO of OSE Immunotherapeutics, about the company’s off-the-shelf cancer vaccine, non-small cell lung cancer, and how it is leveraging its immune system expertise through partnerships with leading pharmaceutical companies.

A Nose for Attacking Brain Cancer

One of the challenges in treating brain cancer and other diseases of the central nervous system is delivering therapeutics beyond the blood-brain barrier. NeOnc Technologies using a natural compound derived from essential oils in plants that not only can kill cancer cells, but can cross the blood-brain barrier. What’s more, it can transport other therapies as well. We spoke to Thomas Chen, founder and CEO of NeOnc, about brain cancer, how the blood-brain barrier complicates the delivery of therapies to treat the condition, and how its experimental candidate that is delivered intranasally works.
