This protocol applies to patients with newly diagnosed nonepithelioid (biphasic or sarcomatoid) pleural mesothelioma who had no medical contraindication to immunotherapy, received first-line immunotherapy, and have since experienced disease progression.
The recommended first-line approach for nonepithelioid pleural mesothelioma is immunotherapy — either ipilimumab plus nivolumab, or chemoimmunotherapy with pembrolizumab combined with pemetrexed plus platinum-based chemotherapy. When absence of disease progression is not maintained, this next-line protocol is indicated.
After first-line immunotherapy, a platinum-based chemotherapy combination is among the options that may be considered — the full selection criteria, sequencing algorithm, and complete regimen details are available in the structured protocol.
