What the trial was testing
The trial enrolled 74 patients with mesothelioma. The study was sponsored by Epizyme and tracked outcomes across the full group of patients who matched the trial's eligibility profile.
It was initial testing (phase 2). Trials at this stage are designed to produce evidence regulators and physicians can act on — not just observations to follow up later.
What the results showed
54% had stable disease or tumor shrinkage at 12 weeks.
The Lancet Oncology · 2022 · NCT02860286
These findings — that at 12 weeks in BAP1-mutated relapsed mesothelioma on tazemetostat — were published in the The Lancet Oncology and represent the headline result of the study.
Researchers tracked outcomes across 74 patients enrolled in the trial. The result was consistent enough across the group that the team felt confident reporting it.
What this means for patients
For patients with mesothelioma, this result changes the calculus on what to ask their care team about. Whether it changes day-to-day care depends on factors like disease subtype, prior treatments, and where the patient is in their care journey.
What you can do now
Tazemetostat (Tazverik) is FDA-approved for some sarcomas and lymphomas but is not yet approved for mesothelioma. Standard mesothelioma treatments are FDA-approved and available now, including the chemo combination pemetrexed-platinum and the immunotherapy combo nivolumab-ipilimumab. Ask a thoracic oncologist about open trials and approved options.
Eligibility for the treatments mentioned above depends on specific test results and clinical history. Bring this summary, the trial name, and your most recent labs or pathology report to your next visit.

Impact of Cardiac Coherence on Anxiety in Patients Operated on for a Peritoneal Carcinosis
The investigator proposes to use the cardiac coherence technique to diminish anxiety before the surgery of a peritoneal carcinosis of colon or stomach or ovary and pseudomyxoma or peritoneal mesothelioma.
Partial Pleurectomy (Surgery) for Unresectable Pleural Mesothelioma
Purpose of the study: The main purpose of this research study is to see if a surgery procedure (limited partial pleurectomy and decortication) helps symptoms in people who have cancer that is unresectable that might not be able to be removed completely. This is called unresectable cancer. This study will also help the research team learn more about the types of symptoms and quality of life for people who have undergone this surgery, the number of complications following , and the time from surgery to starting other therapy. Th e study team also wants to see see the overall survival of people who have had this procedure as part of their care. What will be done as part of research on this study: * Surgery (Partial Pleurectomy - surgery to remove lining of lungs) * The research team will also ask study participants questions about their symptoms through questionnaires at certain times after surgery. How long this study will last: Participation in this research (pre-surgery, surgery and follow-up) will last for about 2 years. Confidentiality: All personal information will be kept confidential, and data will be used only for research purposes.
