Summary

To evaluate the efficacy of sirolimus by estimating the overall response rate (ORR) as assessed by Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST v1.1) in patients with metastatic dMMR solid cancer after immunotherapy (either due to disease progression or to inability to tolerate treatment).

Description

Despite recent therapeutic strategies, including immunotherapy, treatment alternatives for patients with metastatic mismatch-repair deficient (dMMR) solid tumors remain scarce. Pre-clinical data suggests that dMMR tumors are susceptible to rapamycin (sirolimus), a mTOR inhibitor. In these tumors, characterized by higher levels of oxidative stress, sirolimus can exert a cytotoxic effect, led by the failure to repair DNA damage by inhibition of antioxidant enzymes such as FOXO3a triggered by Akt hyperactivation.

This proposal presents a phase 2 clinical trial designed to evaluate the efficacy of sirolimus in patients with dMMR solid tumors after immunotherapy. The investigators hypothesize that sirolimus will increase the overall response rate (ORR) by 20%.
