Abstract
Objectives
To address the issue that most microsatellite-stable (MSS) and proficient mismatch repair (pMMR) metastatic colorectal cancer (mCRC) patients have minimal response to immunotherapy, this meta-analysis evaluated the efficacy and safety of durvalumab and tremelimumab with concomitant treatment in treating MSS/pMMR metastatic colorectal cancer.
Methods
All included trials were prospective studies with a median patient age of 63 years, of which 94.2% were MSS/pMMR mCRC patients, with a male to female ratio of 1.5:1. Based on durvalumab and tremelimumab treatment, one study performed surgical resection on resectable cases, while the other four studies performed radiotherapy or chemotherapy on unresectable cases. Analyses include objective response rate (ORR).etc. for drug activity, overall survival (OS) and progression-free survival (PFS) for therapeutic efficacy, and adverse events (AEs) for safety. The risk of bias was assessed by sensitivity analysis.
Results
5 studies involving 228 patients were included in this meta-analysis. The pooled estimates showed a median OS of 9.26 months, median PFS of 2.53 months, partial response (PR) of 13.6%, stable disease (SD) of 32.8%, ORR of 12.5% and disease control rate (DCR) of 65.4%. AEs were generally low, with pruritus (27.5%), diarrhea (28.8%), and fatigue (53.9%) being the most common, while other AEs occurred at less frequencies.
Conclusions
Durvalumab and tremelimumab with concomitant treatment for MSS/pMMR mCRC patients is relatively effective and safe, which is helpful in addressing the problem of mCRC with MSS/pMMR that has minimal response to immunotherapy.
