简要总结
REGONIVO is a Phase Ib study to explore the efficacy and safety of regorafenib in combination with nivolumab in the treatment of gastric cancer and colorectal cancer with MSS. The study enrolled 50 patients with advanced disease, including 25 cases of gastric cancer, 25 cases of colorectal cancer, except for one case of colorectal cancer with MSI-H, and others were MSS type. The results of the study showed that patients with colorectal cancer had an objective response rate (ORR) of 36% and a progression-free survival (PFS) of 6.3 months.
Based on the preliminary results of the REGONIVO study, the aim of this phase 2 study is to explore the safety and efficacy of regorafenib and PD-1 antibody with or without radiotherapy in previously treated metastatic colorectal cancer patients with pMMR/MSS.

- •Subjects with metastatic colorectal cancer(CRC) (Stage IV).
- •Subjects must have failed at least two lines of prior treatment.
- •Tumor tissues were identified as mismatch repair-proficient (pMMR) by immunohistochemistry (IHC) method or microsatellite stability (MSS) by polymerase chain reaction (PCR).
- •Progression during or within 3 months following the last administration of approved standard therapies which must include a fluoropyrimidine, oxaliplatin and irinotecan.
- •Subjects treated with oxaliplatin in an adjuvant setting should have progressed during or within 6 months of completion of adjuvant therapy.
- •Subjects who progress more than 6 months after completion of oxaliplatin containing adjuvant treatment must be retreated with oxaliplatin-based therapy to be eligible.
- •Subjects who have withdrawn from standard treatment due to unacceptable toxicity warranting discontinuation of treatment and precluding retreatment with the same agent prior to progression of disease will also be allowed into the study.

结局指标
主要结局
The progression-free survival (PFS) rates at 6 months
时间窗: 2 year
The PFS is defined as the time from the start of treatment to the date of first documented PD or death as a result of any cause, whichever occurred first. When a patient was alive and without progression, PFS was censored at the date of the last disease assessment. The PFS rates at 6 months was estimated from Kaplan-Meier curves.
次要结局
- Disease Control Rate (DCR)(2 year)
- The percentage of subjects with total number of Complete Response (CR) + total number of Partial Response (PR).(2 year)
- Overall Survival (OS)(2 year)
- Safety variables will be summarized using descriptive statistics based on adverse events collection(2 year)
