Bacteriophages have long been used to treat infections. These naturally occurring virus are capable of killing bacteria, but each strain of phage is highly specific. Because of their unique mechanism of action, they provide a potential to address the growing threat posed by multidrug-resistant bacteria, but to treat someone, the right phage must be matched to each patient’s infection. Adaptive Phage Therapeutics believes it’s found a way to create phage therapies suited to treat patients with drug-resistant infections by building a bank of targeted and genomically-screened bacteriophage and testing individual patient’s bacterial colony against that to determine the appropriate phage to treat them. We spoke to Greg Merril, co-founder and CEO of Adaptive Phage Therapeutics, about the origins of the company, how its technology works, and the regulatory hurdles for producing customized therapies to treat individual patients.

As a medical student, David Fajgenbaum nearly died from Castleman disease, a rare autoimmune condition. He would suffer recurring bouts that carried him to the brink of death but was able to push the disease into remission by discovering a drug that could be repurposed to treat the disease. Fajgenbaum co-founded the Castleman Disease Collaborative Network and developed a unique approach to research that is now being adopted by other rare disease organizations. He tells his story in his book “Chasing My Cure.” When the COVID-19 outbreak began, Fajgenbaum recognized that the deadliest aspect of the disease—a hyperactive immune response known as a cytokine storm—shared a common link with Castleman disease. He hoped that a researcher would apply his approach to finding a potential drug to repurpose to treat the virus and soon enlisted his own team to do so. We spoke to Fajgenbaum, assistant professor at the Perelman School of Medicine at the University of Pennsylvania and co-founder and executive director of the Castleman Disease Collaborative Network, about his own experience, how it led him to work on COVID-19, and his effort to help researchers and clinicians track all of the drugs being tried to treat the pandemic virus.

As some jurisdictions move to lift shelter in place orders and seek to restore economic life to normal, there’s growing concerns about the health consequences of moving too fast and the failure to make decisions without adequate testing to guide the process. Fred Brown, president and chief operating officer of the big data health consulting firm Fred Brown Management Consulting, discussed beating the COVID-19 pandemic ahead of a piece he’s writing for the fall issue of the Journal of Commercial Biotechnology. Brown offers a few scenarios but believes it will take time for life to return to what it was like. We spoke to Brown about the path to vaccines and therapies, what it will take to move beyond the pandemic, and what we’re learning from this pandemic that will help prepare us for the next one.

Targeting the epigenome—the regulators that turn on and off the activity of genes—has long been viewed as a promising way to treat cancer. But despite the promise of this approach, early efforts brought few successes in part because of the broad effects of hitting these targets. Constellation Pharmaceuticals is taking a next-generation approach to epigenetics, targeting what it calls the writer, reader, and eraser classes of epigenetic regulators to modulate gene expression in a highly selective manner. It believes its approach can be used to both induce cancer cell killing, as well as enhance anti-tumor immunity. We spoke to Jigar Raythatha, president and CEO of Constellation Pharmaceuticals, about epigenetics, the company’s approach to developing highly selective therapies that target gene regulators, and its programs in myelofibrosis and prostate cancer.

Acepodia has developed platform technology that allows it to chemically modify or conjugate living cell surfaces. The technology can be applied to any immune cell and any antibody or binding protein, without the use of genetic engineering. The company is working to apply the technology to create a family of cost-effective, off-the-shelf immunotherapies. We spoke to Sonny Hsiao, CEO of Acepodia, about the company’s platform technology, how it works, and it why it has the potential to change the cost and efficacy of immunotherapies.

One of the challenges to securing the participation of patients in clinical trials can be simple geography. Sanguine Biosciences is seeking to tear down that barrier to participation by using mobile technology to bring clinical trials to patients. The company recently partnered with Vir Biotechnology to complete a COVID-19 clinical study aimed at better understanding the biology of the disease by sending healthcare personnel to collect blood samples from patients at their homes. We spoke to Brain Neman, co-founder and CEO of Sanguine, about it use of digital health technologies, how the company works, and its recent collaboration with Vir Biotechnology for a COVID-19 study.

One of the challenges cell and gene therapies pose is how to control how much and when a desired protein is delivered. Obsidian Therapeutics has developed a platform that allows a small molecule drug to control with precision the timing and level of protein expression from these therapies. We spoke to Paul Wotton, CEO of Obsidian Therapeutics, about the company’s platform technology, how it works, and how it may improve the safety and efficacy of cell and gene therapies.

Patrick Soon-Shiong likes to talk about the “triangle offense,” the activation of a combination of macrophages, natural killer cells, and memory T-cells to battle cancer. He believes the same approach he has been working to train on cancer can be enlisted in the fight against COVID-19, the virus behind today’s global pandemic. We spoke to Soon-Shiong, chairman and CEO of NantKwest, about his approach to immunotherapy, what results he’s seen to date, and why he believes what he’s learned about harnessing the immune system in the fight against cancer can be applied to treating COVID-19.

The COVID-19 pandemic is threatening to stress healthcare systems throughout the world and it is making the development of a vaccine an important part of a strategy to arrest the virus. Though clinical trials for a vaccine are under way, creating a vaccine alone will not be enough. If those efforts are successful, there will be challenges ahead with manufacturing, distributing, and providing equitable access throughout the world. We spoke to Aurélia Nguyen, managing director for vaccines and sustainability for the The Global Alliance for Vaccines and Immunizations about the COVID-19 outbreak, how it may be playing out in different parts of the world, and what was learned from GAVI involvement in previous efforts to develop an ebola vaccine.

Early detection is a critical means of improving outcomes for cancer patients. When cancer is detected at stage I, patients have a 90 percent chance of survival. By contrast, if cancer is diagnosed at stage IV, patients have just a 5 percent or survival. The use of costly and invasive diagnostic approaches have been a barrier to early detection, but new technology has the potential to change that. Laboratory for Advanced Medicine is developing a simple blood-based test to detect cancer at its earliest stage. We spoke to Ken Chahine, CEO of Laboratory for Advanced Medicine, about the company’s blood-based test, how it works, and how it is prioritizing indications.
