Industry Veteran Jane Pritchett Henderson Named Chief Financial Officer

Additional Leaders Hired to Advance Next-Generation Oncolytic Viral Immunotherapies

Turnstone Biologics, a clinical-stage immuno-oncology company developing the next generation of oncolytic viral therapies, today announced the appointment of Jane Pritchett Henderson as Chief Financial Officer. Ms. Henderson brings nearly 30 years of experience as a health care investment banker and financial leader at several biotechnology companies, most recently as the CFO and SVP of Corporate Development of Voyager Therapeutics. In addition, Turnstone announced key hires across its leadership team including: Kristin Gustafson, Senior Vice President, Human Resources and Facilities; Steve Bernstein, M.D., Senior Vice President, Clinical Research and Development; David Stojdl, Ph.D., Senior Vice President, Discovery Research; and Adina Pelusio, Ph.D., Vice President, Clinical Operations.

“I am delighted to welcome Jane, Kristin, Steve, David and Adina to Turnstone and believe each will play a critical role as we continue our relentless pursuit to bring forward important new viral immunotherapies to patients,” said Sammy J. Farah, Ph.D., Chief Executive Officer of Turnstone Biologics. “These key additions round out our exceptional team of senior leaders and top-tier scientists. As we enter this new and exciting phase as a company, I look forward to collaborating with Jane and Kristin to accelerate our corporate development, and with Steve, David and Adina to enhance our research and clinical capabilities.”

Turnstone’s MG1 virus is the first immunotherapy engineered to function as both a systemically delivered tumor-destroying oncolytic virus and an immune stimulating T cell vaccine. MG1 directly attacks cancer cells and modifies the microenvironment to make tumor sites throughout the body susceptible to targeted killer T cell responses, also induced by the virus. Turnstone has initiated multiple Phase I/II clinical trials with medicines targeting MAGEA3-expressing tumors, such as non-small cell lung cancer, and HPV positive tumors, such as cervical and head and neck cancers, and expects to have multiple additional therapies in the clinic by 2019.

“I am thrilled to join Turnstone’s world-class team of immuno-oncology leaders at this exciting time for the company,” said Ms. Henderson. “Turnstone is rapidly advancing a novel pipeline of therapies based on innovative and transformative platforms and is establishing a leadership position in oncolytic viral-based medicines, thereby expanding the number of patients who can benefit from these immunotherapies. I look forward to working closely with Sammy and the team to deliver on these important initiatives.”
