Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with stage I-IIIa sarcomatoid or sarcomatoid-dominant biphasic pleural mesothelioma.

Probably not a fit

Patients with prior treatments affecting the primary neoplasm or those with non-measurable disease may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase II trial evaluates the safety and effectiveness of administering immunotherapy with nivolumab and ipilimumab prior to surgery in patients with stage I-IIIa sarcomatoid mesothelioma. The study aims to determine the percentage of patients who can undergo surgery after receiving this neoadjuvant treatment and to assess the progression-free survival rate at 12 months. Secondary objectives include evaluating surgical complications and treatment response rates. Patients will undergo imaging studies throughout the trial to monitor disease progression.

Why it matters

Potential benefit: If successful, this approach could improve surgical outcomes and disease control for patients with sarcomatoid mesothelioma.

How similar studies have gone: Other studies have shown promise with immunotherapy in similar contexts, suggesting potential for success in this approach.

* STEP 2 ELIGIBILITY CRITERIA: Completion of at least 1 cycle of treatment and not have an unresolved adverse event that would preclude surgery
* STEP 2 ELIGIBILITY CRITERIA: No evidence of progression that would preclude resection
