Parabilis Medicines: Bullish On Zolucatetide's Broad Oncology Potential

Zolucatetide gives PBLS potential in desmoid tumors, but it also has other Wnt-driven indications that could grow its TAM over time. PBLS's PEDESTAL trial is now a clearer R&D path, as long as early responses are corroborated in that Phase 3 study for tumor control. Management's runway projection also suggests they have flexibility and should be able to reach pivotal milestones with Zolucatetide.

Parabilis Medicines Presents Updated Phase 1/2 Data for Zolucatetide Demonstrating Compelling Efficacy and Favorable Safety and Tolerability Profile in Patients with Desmoid Tumors

CAMBRIDGE, Mass., Oct. 24, 2026 (GLOBE NEWSWIRE) -- Parabilis Medicines (Nasdaq: PBLS), a clinical-stage biopharmaceutical company dedicated to creating extraordinary medicines for patients with serious diseases by unlocking historically undruggable targets, today announced updated safety and efficacy data for zolucatetide, the first and only direct inhibitor of the β-catenin:TCF interaction, in patients with desmoid tumors. The data were presented today in an oral presentation at the European Society for Medical Oncology (ESMO) Congress 2026, taking place October 23–27, 2026, in Madrid, Spain. The updated results, based on a June 22, 2026, data cutoff, include data from both the dose escalation and dose optimization portions of the ongoing Phase 1/2 trial and reinforce the strong efficacy and favorable safety and tolerability profile observed with zolucatetide. Among response-evaluable patients who began treatment at a starting dose of ≥450 mg, zolucatetide demonstrated an objective response rate (ORR) of 72.2% (13/18) in a 32-week landmark analysis. A disease control rate (DCR) of 100% was observed across all 46 response-evaluable patients who received a starting dose of ≥450 mg, with no disease progression. Data from a three-arm randomized dose optimization trial supported selection of a 450 mg weekly induction regimen administered for four cycles, followed by 300 mg every two weeks for long-term maintenance. Following productive end-of-Phase 2 discussions, Parabilis has reached alignment with the U.S. Food and Drug Administration (FDA) on the selected dose and regimen, on the use of a placebo-controlled study design, and on progression-free survival (PFS) as the primary endpoint for registrational development. Parabilis plans to initiate the randomized, double-blind PEDESTAL Phase 3 trial (Phase 3 Evaluation of DESmoid Tumor Activity with zoLucatetide) in the first half of 2027, with topline results anticipated in 2029. “Desmoid tumors are chronic and life-altering for patients, often affecting people at a young age, and patients need treatments that can deliver rapid, deep and durable tumor responses with a tolerability profile suited for long-term treatment,” said Mathai Mammen, M.D., Ph.D., Chairman, CEO and President of Parabilis Medicines. “We designed zolucatetide to directly inhibit β-catenin:TCF, a historically undruggable target at the heart of the biology driving these tumors. The depth and consistency of responses we are seeing, together with the favorable safety and tolerability profile observed to date, reinforce our conviction that zolucatetide has the potential to deliver a truly differentiated medicine and meaningfully expand the number of patients who can benefit from treatment. We are very pleased with the clarity of the FDA's feedback on our registrational development strategy, and with our Phase 3 regimen selected, we are moving with urgency to bring this medicine to patients.” Updated Phase 1/2 Results As of the June 22, 2026, data cutoff, 76 patients with desmoid tumors had been enrolled and treated across all dose levels in the dose escalation and dose optimization portions of the trial. Median age was 37 years (range 19–80), and 69.7% of patients were female. The population included both patients who had previously been treated with and failed gamma-secretase inhibitors (GSIs) and patients naive to GSIs.
