Phase 1, Multi-Center, Open-Label, Study to Evaluate the Safety, Tolerability, and PK of VT3989 in Patients With Refractory Locally Advanced or Metastatic Solid Tumors Enriched for Tumors Harboring Mutations of the NF2 Gene
This is an open-label, dose escalation and expansion study to evaluate the safety, tolerability, PK, and biological activity of VT3989 administered once-daily in patients with advanced pleural malignant mesothelioma and/or metastatic solid tumors that are resistant or refractory to standard therapy or for which no effective standard therapy is available.
In Dose Expansion, patients will be enrolled into 2 cohorts: Cohort 1 - malignant pleural mesothelioma patients with mutations of NF2 that have progressed on or following standard therapy; and Cohort 2 - solid tumor patients with mutations of NF2 that have progressed on or following standard therapy. Patients will be treated at the MTD or RP2D identified in Part 1, to provide further characterization of the safety, tolerability, efficacy, and biological activity of VT3989.
