About

This is a global, randomized, double-blind, placebo-controlled, multicenter phase 3 clinical trial to compare the efficacy and safety of fruquintinib plus best supportive care (BSC) versus placebo plus BSC in participants with refractory metastatic colorectal cancer (mCRC). 691 participants were randomized to one of the following treatment arms in a 2:1 ratio, fruquintinib plus BSC or placebo plus BSC.

Full description

This is a global, randomized, double-blind, placebo-controlled, multicenter phase 3 clinical trial to compare the efficacy and safety of fruquintinib in combination with BSC versus placebo in combination with BSC in metastatic colorectal cancer participants who have progressed on, or were intolerant to, chemotherapy, anti-VEGF and anti-EGFR biologics, and TAS-102 or regorafenib. Participants with MSI-H/MMR deficient tumors must have also received an immune checkpoint inhibitor if approved and available and if deemed appropriate. Subjects with BRAF-mutant tumors must have been treated with a BRAF inhibitor if approved and available and if deemed appropriate. Metastatic colorectal cancer cannot be cured by surgery. Therefore, treatment principals are primarily aimed at controlling disease progression and prolonging survival. Standard first- and second-line therapy includes cytotoxic drugs such as 5-fluorouracil, oxaliplatin, and irinotecan; anti-VEGF therapy; and, if RAS wild type, anti-EGFR therapy. After the first two lines of chemotherapy, standard third-line treatment is either TAS-102 or regorafenib. There are currently no effective treatments for patients who have progressed on standard, approved therapies, and treatment options include reuse of prior therapies, clinical trials or BSC. Consequently, there is an unmet medical need for additional safe and effective treatment.

Inclusion criteria

  • 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;
  • Participants must have progressed on or been intolerant to treatment with either trifluridine/tipiracil (TAS-102) or regorafenib. Participants 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. Participants who have been treated with both TAS-102 and regorafenib are permitted. Participants 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;
  • Participants 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 participant's country unless the patient is ineligible for treatment with a checkpoint inhibitor;
  • Participants 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. Participants 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 participants of childbearing potential and male participants 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 participant. Highly effective contraception should always be combined with an additional barrier method (eg, diaphragm, with spermicide). The same criteria are applicable to male participants involved in this clinical trial if they have a partner of childbirth potential, and male participants must always use a condom.
  • Participants with BRAF-mutant tumors must have been treated with a BRAF inhibitor if approved and available in the participant's home country unless the patient is ineligible for treatment with a BRAF inhibitor.

Exclusion criteria

  • Absolute neutrophil count (ANC) <1.5×109/L, platelet count <100×109/L, or hemoglobin <9.0 g/dL. Blood transfusion within 1 week prior to enrollment for the purpose of increasing the likelihood of eligibility is not allowed;
  • Serum total bilirubin >1.5 × the upper limit of normal (ULN). Participants with Gilbert syndrome, bilirubin <2 X ULN, and normal AST/ALT are eligible;
  • Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >2.5 × ULN in participants without hepatic metastases; ALT or AST >5 × ULN in participants with hepatic metastases;
  • Serum creatinine >1.5 × ULN or creatinine clearance <60 mL/min. Creatinine clearance can either be measured in a 24-hour urine collection or estimated by the Cockroft-Gault equation.
  • Urine dipstick protein ≥2+ or 24-hour urine protein ≥1.0 g/24-h. Participants with greater than 2+ proteinuria by dipstick must undergo a 24-hour urine collection to assess urine protein level;
  • Uncontrolled hypertension, defined as: systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg despite optimal medical management. Participants were required to have blood pressure values below both limits. Repeated assessments were permitted;
  • International Normalized Ratio (INR) >1.5 x ULN or activated partial thromboplastin time (aPTT) >1.5 × ULN, unless the patient is currently receiving or intended to receive anticoagulants for prophylactic purposes;
  • History of, or active gastric/duodenal ulcer or ulcerative colitis, active hemorrhage of an unresected gastrointestinal tumor, history of perforation or fistulas; or any other condition that could, in the investigator's judgment, result in gastrointestinal hemorrhage or perforation; within the 6 months prior to screening;
