Evaluating VT3989 for patients with metastatic solid tumors

Phase I/II, Multi-Center, Open-Label Study of VT3989, Alone or in Combination, in Patients With Locally Advanced or Metastatic Solid Tumors

Phase1; Phase2 Interventional Vivace Therapeutics, Inc · NCT04665206

This study is testing a new drug called VT3989 to see if it can help people with hard-to-treat metastatic solid tumors, including mesothelioma, feel better and fight their cancer.

What this trial studies

This open-label, dose escalation and expansion study aims to assess the safety, tolerability, pharmacokinetics, and biological activity of VT3989 in patients with mesothelioma and metastatic solid tumors that are resistant or refractory to standard therapies. The study will utilize a traditional 3 + 3 design to determine the maximum tolerated dose (MTD) and will include multiple cohorts for dose expansion to evaluate preliminary antitumor activity. Patients will receive VT3989 alone or in combination with immunotherapy or targeted therapy based on their specific tumor characteristics.

Who should consider this trial

Good fit: Ideal candidates include adults with metastatic solid tumors or mesothelioma that have progressed after standard therapies.

Not a fit: Patients with tumors that are not metastatic or those who have not exhausted standard treatment options may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced solid tumors that have limited or no effective therapies available.

How similar studies have performed: Other studies have shown promise with similar approaches, particularly in targeting resistant solid tumors, suggesting potential for success in this novel application.
