Descriptiontext

Vivace Therapeutics is a San Mateo, California-based clinical-stage oncology biotech founded in 2015 that discovers and develops small-molecule therapeutics targeting the Hippo-YAP signaling pathway. Its lead asset, VT3989, is a first-in-class TEAD autopalmitoylation inhibitor designed to block YAP-TEAD transcription activity, the effector mechanism of the Hippo pathway whose dysregulation drives cancers including mesothelioma, meningioma, schwannoma, and NF2-mutated tumors. In a Phase I/II study, VT3989 generated a 32% overall response rate, an 86% disease control rate, and a median progression-free survival of 40 weeks in refractory mesothelioma patients, supporting the company's plan to initiate a Phase 3 trial in 2026. The asset has received FDA Fast Track Designation and Orphan Drug Designation for mesothelioma.

The company operates a pre-commercial, capital-efficient model: it has raised approximately $105 million across multiple venture rounds (notably a $35M Series D in 2025 led by RA Capital Management, a $30M Series C in 2020, and earlier rounds from Canaan Partners, Cenova Capital, WuXi Healthcare Ventures, Boxer Capital, Sequoia, and Mission Bay Capital). Its current revenue model is one-time out-licensing/partnership-driven upon potential future commercialization, with no product on market and no disclosed pricing. Go-to-market relies on scientific publications, oncology conference presentations (ESMO, AACR, EORTC-NCI-AACR), clinical trial site execution, and future regulatory/commercial partnerships. Customer-facing activity today centers on clinical investigators and trial patients in mesothelioma and NF2-mutated tumor cohorts, with optionality indicated for additional cancers and non-oncology indications such as fibrotic disease.

The company will advance VT3989, a TEAD inhibitor, into Phase 3 sTEADfast trial in mesothelioma, with FDA safe-to-proceed granted. The trial is expected to initiate later this year.CuretodayFDA Grants Fast Tract Designation to VT3989 for MesotheliomaThe U.S. Food and Drug Administration (FDA) has granted fast track designation to VT3989, an investigational small molecule therapeutic developed by Vivace Therapeutics, for the treatment of unresectable malignant mesothelioma. This designation aims to expedite the development and review process for drugs addressing serious conditions with unmet medical needs. The therapy is currently being evaluated in a phase 1 clinical study recruiting patients in the United States and Australia.OncLiveFDA Grants Fast Track Designation to VT3989 for Unresectable MesotheliomaThe FDA has granted fast track designation to VT3989, a TEAD autopalmitoylation inhibitor developed by Vivace Therapeutics, for the treatment of unresectable mesothelioma in patients who have progressed on prior therapies. Preliminary results from an ongoing phase 1/2 trial indicate tumor response in mesothelioma patients regardless of NF2 mutation status. This designation provides key advantages for Vivace Therapeutics as it continues development toward potential commercialization.The ASCO PostVT3989 Demonstrates Antitumor Activity and Tolerability in Refractory MesotheliomaVivace Therapeutics' first-in-class YAP-TEAD inhibitor VT3989 demonstrated antitumor activity and tolerability in a phase I/II trial for patients with refractory mesothelioma. The study reported an objective response rate of 32% and a disease control rate of 86%, leading to plans for a phase III trial. The FDA has granted Orphan Drug and Fast Track designations to VT3989 for this indication.FierceBiotechESMO: Vivace tunes up for phase 3 after midstage mesothelioma trial hits high noteCancer biotech Vivace Therapeutics announced that its experimental drug VT3989 achieved a 32% objective response rate in patients with treatment-resistant mesothelioma, prompting plans to launch a phase 3 trial in the first half of 2026. The results, presented at the ESMO Congress and published in Nature Medicine, showed that treated patients had more than double the median progression-free survival compared to standard salvage chemotherapy benchmarks.MdandersonESMO 2025: VT3989 continues to show promising early results in patients with advanced mesotheliomaVivace Therapeutics reported that its YAP-TEAD inhibitor VT3989 demonstrated an 86% disease control rate in patients with refractory mesothelioma during Phase I/II trials presented at the ESMO 2025 Congress. The data provided the first clinical proof-of-concept for inhibiting the Hippo-YAP-TEAD pathway, showing significant disease control even in heavily pretreated patients with a favorable safety profile. These results support the continued clinical development of VT3989 for this unmet medical need.BioSpaceVT3989, Vivace Therapeutics’ Best-in-Class, Hippo Pathway-Targeting Therapy, Demonstrates Promising Antitumor Activity in Refractory MesotheliomaVivace Therapeutics announced positive Phase 1/2 clinical trial data for VT3989, its first-in-class TEAD autopalmitoylation inhibitor targeting the Hippo pathway, in 22 refractory mesothelioma patients treated at the optimized Phase 3 dose. The therapy achieved a 32% objective response rate, 86% disease control rate, and a median progression-free survival of 40 weeks—more than double the 15-week benchmark for standard-of-care salvage chemotherapy—with a manageable safety profile. Based on these results, Vivace plans to advance VT3989 into a registrational Phase 3 trial in the first half of 2026, and the therapy has received FDA Orphan Drug and Fast Track Designations for mesothelioma.PR NewswireNew Clinical Data for Vivace Therapeutics' Best-in-Class, Hippo Pathway-Targeting Therapy to be Presented in Oral Presentation at the European Society for Medical Oncology (ESMO) Congress 2025Vivace Therapeutics announced that new clinical data for VT3989, its first-in-class TEAD autopalmitoylation inhibitor targeting the Hippo pathway, will be presented at the ESMO Congress 2025 in Berlin, Germany on October 19. The drug, being studied in a Phase 1/2 trial for refractory malignant mesothelioma, previously demonstrated good tolerability and durable antitumor responses in patients with advanced solid tumors. Dr. Timothy A. Yap from MD Anderson Cancer Center will deliver the oral presentation, supporting VT3989's potential as a best-in-class cancer therapeutic.PR NewswireVivace Therapeutics' VT3989 Granted Fast Track Designation by the U.S. Food and Drug Administration for the Treatment of MesotheliomaThe FDA granted Fast Track Designation to Vivace Therapeutics' VT3989 as a treatment for patients with unresectable malignant mesothelioma whose disease has progressed on prior immune checkpoint inhibitor therapy and platinum-based chemotherapy. VT3989, a first-in-class TEAD autopalmitoylation inhibitor, has demonstrated compelling clinical efficacy data and a positive safety profile in over 200 patients enrolled in an ongoing Phase 1 clinical trial. The designation enables more frequent FDA interactions and potential eligibility for accelerated approval and priority review as the company advances toward potential commercialization.
