Summary

Researchers are comparing an experimental oral drug called VT3989 with standard chemotherapy drugs gemcitabine or vinorelbine in adults with advanced epithelioid pleural mesothelioma. All participants have already received platinum-based chemotherapy and immunotherapy, and their cancer has progressed. The trial aims to see if VT3989 helps people live longer than the usual chemotherapy options. About 350 people will join this Phase 3 study.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
VT3989, an experimental oral drug
What this could lead to
If VT3989 works, it could offer a new oral option for people with advanced epithelioid mesothelioma whose cancer worsened after standard chemotherapy and immunotherapy.
What could go wrong
This is a Phase 3 trial, so the drug's benefit is not yet proven. VT3989 may not extend survival better than gemcitabine or vinorelbine, and it can cause side effects that limit its use.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Male or female, age 18 years or older at informed consent. * Pathologically confirmed advanced epithelioid pleural mesothelioma previously treated with platinum-based systemic chemotherapy and immunotherapy, given sequentially or concurrently. * Radiologically measurable disease by modified RECIST v1.1 or RECIST v1.1. * ECOG: 0-1. * Adequate organ functions, including the liver, kidneys, and hematopoietic system. Exclusion Criteria: * Active brain metastases or primary CNS (central nervous system) tumors. * History of leptomeningeal metastases * Active or chronic, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy * Known HIV positive or active Hepatitis B or Hepatitis C * Clinically significant cardiovascular disease and prior exposure to cardiotoxic agents * Corrected QT (QTcF) interval \> 470 msec (using Fridericia's correction formula). * Women who are pregnant or breastfeeding * Non-pleural mesothelioma at initial diagnosis or an aggressive histologic type such as sarcomatoid or biphasic mesothelioma. * Prior treatment with a TEAD inhibitor, including VT3989 or another agent targeting the same molecular pathway. * Prior receipt of both comparator treatments, gemcitabine and vinorelbine, alone or in combination, or known hypersensitivity to both. A participant who received only one comparator may enroll but must not be assigned to that same comparator.
