Parabilis Medicines™ is a clinical-stage biopharmaceutical company dedicated to creating extraordinary medicines for patients with serious diseases by unlocking biologically important targets long considered undruggable. The company has pioneered a new class of alpha-helical peptides – Helicons™ – capable of modulating intracellular proteins that have historically been beyond the reach of conventional medicines. The company’s lead investigational medicine, zolucatetide, is the first and only direct inhibitor of the β-catenin:TCF interaction, a central node in the Wnt/β-catenin pathway that has eluded drug developers for decades. Zolucatetide is being evaluated in the clinic across multiple Wnt/β-catenin-driven diseases, including desmoid tumors, familial adenomatous polyposis (FAP) and a range of other solid tumor indications. Beyond zolucatetide, Parabilis is advancing additional Helicon-based programs focused on other challenging targets where we believe our medicines could have life-altering impact.

REVOLUTION Medicines discovers and develops new drugs that harness the therapeutic potential of frontier oncology targets on behalf of cancer patients. Our innovative product engine draws inspiration from nature and evolution, which offer insights into cancer targets, disease mechanisms and therapeutic approaches. We pay particular attention to natural products that are inherently rich with biological function as a result of natural selection and can inform and guide our discovery and development of small molecules that can modulate these targets.

We discover, launch and build great companies based on bold ideas that meet at the intersection of science, strategy, business and medicine – where transformational science meets operational reality – providing the best opportunity to make a dramatic difference in patients’ lives. THE THIRD ROCK TEAM Our team has a proven record of translating disruptive technologies into valuable business enterprises. Working closely with leading scientific and business visionaries as well as industry partners, we identify opportunities to change the future of medicine and rigorously vet those ideas through our discovery process to develop the vision, strategy and plan needed to succeed. A FORMULA FOR INNOVATION We only invest in the best of those ideas. We are actively involved in the early stages of our companies’ development, typically serving as members of the founding management teams, to build a strong foundation, put in place the right people and culture, and set the companies on a path to scientific and operational excellence. We believe in the companies we launch and make big initial investments, often complemented by strategic alliances, to enable our companies to advance life-changing therapies, devices and diagnostics. By creating value for patients, we create value for our investors.
