NCT05942768

Brief Summary

Managements for refractory proficient mismatch repair (pMMR) or microsatellite stable (MSS) metastatic colorectal cancer (mCRC) were still challenging and controversial. Our study sought to investigate the efficacy and safety of anti-PD-1 antibodies plus regorafenib in refractory pMMR/MSS mCRC between July 2019 and June 2021 at the Hunan Cancer Hospital.

Outcome Measures

Primary Outcomes (1)

  • Overall Survival (OS)

    Overall survival defined as the observed time elapsed between the date of commencement of treatment and the date of death due to any cause

    Approximately 12 months

Secondary Outcomes (4)

  • Progression-free survival (PFS)

    Approximately 12 months

  • Overall response rate (ORR)

    Approximately 12 months

  • Disease control rate (DCR)

    Approximately 12 months

  • Treatment-Related Adverse Events (TRAE)

    Approximately 12 months

Interventions

The patients were treated orally with regorafenib (80 mg once daily for 21 days on/7 days off, over a 28-day cycle), combined with 1 of the 5 anti-PD-1 antibodies (i.e., nivolumab, pembrolizumab, camrelizumab, sintilimab, or toripalimab). The anti-PD-1 antibody was administered intravenously on day 1, and its recommended dosage was as follows: nivolumab: 240 mg, every 2 weeks; pembrolizumab, camrelizumab, and sintilimab: 200 mg every 3 weeks; and toripalimab: 240 mg every 3 weeks

Also known as: programmed cell death protein 1, immune checkpoint inhibitor
