Overview

The aim of this clinical study is to learn more about the effects of urolithin A (MitoPure®) on the immune system of cancer patients receiving immune checkpoint inhibitor-based therapies. Any effects will be compared with patients who take a placebo instead of urolithin A (MitoPure®).

3. Age ≥ 18 years
4. Life-expectancy ≥ 3 months
5. Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
