Parabilis to present updated zolucatetide desmoid tumor data at ESMO on Oct. 24

Parabilis Medicines announced that Dr. Mrinal Gounder will present new Phase 1/2 data for its lead drug zolucatetide in desmoid tumors at the European Society for Medical Oncology Congress on Oct. 24. The update adds four months of follow‑up to the previous February cut and includes dose‑optimization results that will guide the upcoming Phase 3 trial. The company highlighted that 74% of patients with at least two scans had shown an objective response as of Feb. 16. Parabilis holds $1.1 billion in cash, which it expects to sustain operations through 2030.

The presentation could confirm the drug’s efficacy and determine the dose for the Phase 3 study, influencing future regulatory approval prospects. The company’s ample cash runway reduces the risk of financing constraints even if the data are weaker than expected.
