Summary

Colorectal cancer (CRC) is the third most common malignant tumor worldwide and the second leading cause of cancer-related deaths. Despite recent progress in CRC research, approximately 15% to 30% of patients have metastatic lesions at the time of initial diagnosis, and another 20% to 50% of patients with primary localized CRC eventually develop metastatic disease. The conventional treatment for first-line metastatic colorectal cancer (mCRC) is chemotherapy based on fluorouracil combined with anti-EGFR/VEGF targeted drugs. However, some mCRC patients may not be able to receive standard dual or triple chemotherapy combined with targeted therapy due to factors such as advanced age, poor physical condition, comorbidities, or personal preferences. Therefore, exploring new, highly effective, and low-toxicity treatment regimens is of significant clinical importance. The combination of immune checkpoint inhibitors and antiangiogenic TKIs is expected to form a strong synergistic antitumor effect, which opens up a new approach for "chemotherapy-free" treatment of mCRC when the immune system is functioning normally. Previously, we conducted the APICAL-CRC study, enrolling a total of 30 patients. The clinical objective response rate (ORR) was 48.3%, the disease control rate was 89.7%, and the median progression-free survival (mPFS) and median overall survival (mOS) were 8.6 months and 22.9 months, respectively. Subgroup analysis later revealed that the ORR for non-liver metastasis patients was 70%, with an mPFS of 14.9 months, significantly higher than that of liver metastasis patients (ORR 36.8%). At the same time, patients with better physical performance scores (ECOG PS 0-1) had an ORR of 66.7%, which was superior to that of patients with ECOG PS 2 (21.4%). In terms of safety, the incidence of grade ≥ 3 treatment-related adverse events (TRAEs) for the combination of anlotinib and sintilimab was only 13.3%. Based on the preliminary results of the APICAL-CRC study, we consider further precise screening of the advantageous population among advanced CRC patients for subsequent research. We plan to limit the enrolled patients to those without liver metastasis and with ECOG PS 0-1, providing new strategies and methods for precise treatment of advanced CRC.The purpose of this study is to evaluate the efficacy and safety of anlotinib combined with sintilimab as first-line treatment for non-liver metastatic advanced colorectal cancer. The study will be conducted at Shanghai Changzheng Hospital. The study drugs, anlotinib and sintilimab, are both marketed drugs in China.
