About Us…

Obsidian Therapeutics is expanding the reach of TIL therapy. We are pioneering engineered tumor infiltrating lymphocyte (TIL) therapies to deliver transformative outcomes for patients suffering from solid tumor malignancies. Obsidian’s programs apply our cytoDRiVE® platform technology to express regulated therapeutic proteins to enhance anti-tumor activity. We’re currently investigating our lead program OBX-115 and enrolling patients in an ongoing clinical trial in advanced or metastatic melanoma.

We’re proud of our diverse talented team and committed to cultivating an environment where each person feels a strong sense of belonging and is supported to continuously learn and contribute their best work. Our research team is based in the heart of Cambridge, MA, and our Technical Development, Manufacturing & Quality team is based in our facility in Bedford, MA. Obsidianites enjoy a highly collaborative culture, competitive salary and benefits, and potential for ownership through stock options.

On April 3, 2024, we announced closure of a significantly oversubscribed $160.5 million Series C financing with a top-tier syndicate of life science investors led by new investor, Wellington Management. Proceeds from the financing will advance Obsidian’s lead program in its ongoing trials. We’re focused on enrolling patients and reaching key clinical and regulatory milestones, as well as manufacturing scale-up ahead of pivotal trial readiness.
