The Bio Report

The Epstein-Barr virus is among the most common viruses associated diseases including multiple sclerosis and certain cancers. Atara Biotherapeutics is developing off-the-shelf, T-cell immunotherapies designed to target cancers and autoimmune conditions driven by the Epstein-Barr virus. It is also using its EBV T-cell platform to develop next-generation allogenic CAR T therapies to target a range of non-EBV associated diseases. We spoke to Pascal Touchon, president and CEO of Atara, about the role of the Epstein-Barr virus in certain cancers and autoimmune conditions, the company’s platform technology for allogenic CAR T therapies, and why it has implications beyond EBV-driven diseases.

Myeloid cells can stimulate anti-tumor effects in the body and recruit additional immune system cells to turn a cold tumor hot. Bolt Biotherapeutics is developing a new category of immunotherapies that combines the precision of antibody targeting with the strength of the innate and adaptive immune systems. By activating and recruiting myeloid cells, the company’s experimental therapies are designed to re-program the tumor microenvironment and invoke an anti-tumor immune response. We spoke to Randy Schatzman, CEO of Bolt Biotherapeutics, about the company’s immune-stimulating antibody conjugates, the case for activating both the innate and adaptive immune systems to fight cancer, and the company’s lead experimental therapy for HER2 positive cancers.

The development of mRNA-based vaccines has represented a major advance in the field of vaccine development. Rather than using weakened or inactivated viruses to stimulate an immune response to generate protective antibodies, mRNA-based vaccines provide a potentially safer and more effective approach. mRNA vaccines work by introducing a small piece of mRNA into the body, which encodes instructions to produce a specific viral protein for the cell to manufacture. This protein then triggers an immune response, leading to the production of antibodies that can protect against specific diseases. Combined Therapeutics has designed a modified mRNA-based vaccine platform that allows for the inhibition of protein expression in specific tissues, enabling targeted vaccine treatment and preventing off-target side effects. It’s designed to be adaptable and efficient, which makes possible rapid production of vaccines for a wide range of diseases and disease variants. We spoke to Thomas VanCott, chief scientific officer of Combined Therapeutics, about the company’s mRNA platform for vaccines, the advantages it provides, and its potential to use the same approach to train the immune system on specific mutations in a tumor.

Infectious diseases and microbial resistance represent major concerns in developing nations. The combination of globalization with the expanded use of antibiotics in resource-constrained environments is worsening the problem. In fact, hospital acquired infection rates in some regions are three times greater than in the United States and as much as 30 percent of all such infections are antimicrobial resistant. HDT Bio is developing immune activators and RNA-based vaccines to address this challenge with cost-effective and accessible medicines. We spoke to Chris Pirie, co-founder and chief operating officer of HDT Bio, about the problem the company is seeking to address, its platform technology for producing safe and stable RNA vaccines, and the potential to use the same platform to produce immunotherapies for cancer.

Bacteriophage are viruses that target bacteria. Though they emerged in the 1920s as treatments for infectious diseases, because of their high level of specificity, they fell out of favor with the advent of broad-spectrum antibiotics. BiomX is developing both natural and engineered phage cocktails designed to target and destroy harmful bacteria in chronic diseases, such as cystic fibrosis, inflammatory bowel disease, and atopic dermatitis. We spoke to Jonathan Solomon, CEO of BiomX, about the case for phage therapies, the company’s approach to creating a phage cocktail that could effectively target a population of patients, and why it's focusing on chronic diseases.

CytoMed, a spin out of A*STAR—Singapore’s Agency for Science, Technology, and Research—is developing novel cell-based immunotherapies that can go beyond the limitations of existing CAR T therapies. The company is focused on the development of off-the-shelf therapies derived from the delta gamma T cells from healthy donors. We spoke to Wee Kiat Tan, chief operating officer of CytoMed, about the company’s platform technology for off-the-shelf CAR T therapies, the advantages they provide over existing autologous CAR T therapies, and why he believes they will be successful at treating solid tumors.

For academic scientists who make groundbreaking discoveries that can lead to new medicines, bridging the so-called valley of death—the gulf between the lab and having a validated candidate that is ready to begin human clinical trials—continues to be daunting. Foundery Innovations, which bills itself as a venture studio, sees a big opportunity in partnering with academic researchers to carry promising new immunotherapies through to the clinic. Its team has deep experience in immunotherapy development and brings a wide range of skills and cutting-edge platform technologies to de-risk development and accelerate the time to the clinic. We spoke to Max Krummel, founder and managing member of Foundery Innovations, about the venture studio’s business model, the resources it brings to bear, and how it works with academic researchers and universities.

Vericel, which acquired Sanofi’s cell therapy and regenerative medicine unit, markets advanced cell therapy products for sports medicine and severe burn care. The company’s MACI is an autologous cellularized scaffold used in the repair of cartilage defects of the knee. Epicel, its cultured epidermal autografts, are a permanent skin replacement for the treatment of patients with deep dermal or full thickness burns greater than or equal to 30 percent of total body surface area. We spoke to Nick Colangelo, president and CEO of Vericel, about the markets the company is targeting, how its products are changing outcomes for patients, and the company’s plans for growth.

Understanding the physical relationship of cells and how they interact can provide new understanding of diseases and help improve drug development and clinical treatment decisions. Nucleai uses its AI-powered spatial biology platform to transform pathology data into insights. The digital assays it develops enhances drug development, supports treatment decisions, and helps stratify patients to improve care. We spoke to Ken Bloom, head of pathology for Nucleai, about the company’s AI spatial biology platform, how it works, and the potential it has to advance precision medicine.

Vaccitech first gained attention as co-inventor of the Covid-19 vaccine licensed to AstraZeneca. The University of Oxford spin-out is developing a pipeline of T cell immunotherapies to treat and cure chronic infectious diseases, autoimmune diseases, and cancers. The company’s lead experimental therapy is a potentially curative monotherapy for chronic hepatitis B viral infection. We spoke to Bill Enright, CEO of Vaccitech, about the company’s platform technologies, how they work, and how they enable the development of more effective immunotherapies.
