To evaluate the overall survival of fruquintinib plus BSC compared to placebo plus BSC in subjects with refractory mCRC.
- Provide written informed consent;
- Age >=18 years;
- Histologically and/or cytologically documented metastatic colorectal adenocarcinoma. RAS, BRAF, and microsatellite instability microsatellite instability (MSI)/mismatch repair (MMR) status for each patient must be documented, according to country level guidelines;
- Subjects must have progressed on or been intolerant to treatment with either trifluridine/tipiracil (TAS-102) or regorafenib. Subjects are considered intolerant to TAS-102 or regorafenib if they have received at least 1 dose of either agents and were discontinued from therapy for reasons other than disease progression. Subjects who have been treated with both TAS-102 and regorafenib are permitted. Subjects must also have been previously treated with standard approved therapies: fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, an anti-VEGF biological therapy, and, if RAS wild-type, an anti-EGFR therapy;
- Subjects with microsatellite-high (MSI-H) or mismatch repair deficient (dMMR) tumors must have been treated with immune checkpoint inhibitors if approved and available in the subject's country unless the patient is ineligible for treatment with a checkpoint inhibitor;
- Subjects who received oxaliplatin in the adjuvant setting and developed metastatic disease during or within 6 months of completing adjuvant therapy are considered eligible without receiving oxaliplatin in the metastatic setting. Subjects who developed metastatic disease more than 6 months after completion of oxaliplatin-containing adjuvant treatment must be treated with oxaliplatin-based therapy in the metastatic setting to be eligible;
- Body weight >=40kg;
- Eastern Cooperative Oncology Group (ECOG) performance status of 0-1;
- Have measurable disease according to RECIST Version 1.1, assessed locally. Tumors that were treated with radiotherapy are not measurable per RECIST Version 1.1, unless there has been documented progression of those lesions;
- Expected survival >12 weeks.
- For female subjects of childbearing potential and male subjects with partners of childbearing potential, agreement to use a highly effective form(s) of contraception, that results in a low failure rate (<1% per year) when used consistently and correctly, starting during the screening period, continuing throughout the entire study period, and for 90 days after taking the last dose of study drug. Such methods include: oral hormonal contraception (combined estrogen/ progestogen, or progestogen-only) associated with inhibition of ovulation, intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal ligation, vasectomized partner, or true sexual abstinence in line with the preferred and usual lifestyle of the subject. Highly effective contraception should always be combined with an additional barrier method (eg, diaphragm, with spermicide). The same criteria are applicable to male subjects involved in this clinical trial if they have a partner of childbirth potential, and male subjects must always use a condom.
- Subjects with BRAF-mutant tumors must have been treated with a BRAF inhibitor if approved and available in the subject's home country unless the patient is ineligible for treatment with a BRAF inhibitor.
