FDA Approval of Fruquintinib for Metastatic Colorectal Cancer
The Food and Drug Administration approved fruquintinib (Fruzaqla, Takeda Pharmaceuticals, Inc.) on November 8, 2023, for adult patients with metastatic colorectal cancer (mCRC) who have undergone specific prior treatments.
Efficacy Evaluation in FRESCO and FRESCO-2 Trials
The effectiveness was assessed in FRESCO-2 (NCT04322539) and FRESCO (NCT02314819). The FRESCO-2 trial (NCT04322539) assessed 691 patients with mCRC who experienced disease progression after previous fluoropyrimidine-, oxaliplatin-, irinotecan-based chemotherapy, anti-VEGF biological therapy, anti-EGFR biological therapy (if RAS wild type), and at least one of trifluridine, tipiracil, or regorafenib. It was an international, multicenter, randomized, double-blind, placebo-controlled study. The FRESCO trial, a multicenter study in China, assessed 416 patients with metastatic colorectal cancer who experienced disease progression following previous fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy.
In both trials, patients were randomly assigned to either get fruquintinib 5 mg orally once a day or a placebo for the first 21 days of each 28-day cycle. They also got the best possible supportive care. Patients were treated until disease progression or unacceptable toxicity occurred.
Clinical Efficacy and Overall Survival Results
The primary effectiveness outcome in both trials was overall survival (OS). The median overall survival in the FRESCO-2 study was 7.4 months (95% CI: 6.7, 8.2) for patients who received fruquintinib and 4.8 months (95% CI: 4.0, 5.8) for those in the placebo group. The hazard ratio was 0.66 (95% CI: 0.55, 0.80) with a p-value of less than 0.001. In the FRESCO study, the median overall survival was 9.3 months (95% CI: 8.2–10.5) for the first therapy group and 6.6 months (95% CI: 5.9–8.1) for the second. The hazard ratio was 0.65 (95% CI: 0.51, 0.83), and the p-value was less than 0.001.
Common Adverse Events and Side Effects
The prevalent side effects (experienced by 20% or more of patients) included hypertension, palmar-plantar erythrodysesthesia, proteinuria, dysphonia, abdominal pain, diarrhea, and asthenia.
Recommended Dosage and Administration
The suggested fruquintinib dosage is 5 mg taken orally once a day, with or without food, for the initial 21 days of a 28-day cycle until disease progression or intolerable toxicity.
How CancerFax Helps
CancerFax is a specialist cancer access and patient-navigation platform. We help patients and families understand their options, organise medical records, coordinate hospital communication, and support cross-border treatment planning where appropriate.
We help collect and organise reports, scans, pathology, biomarker results, and treatment history for structured case review.
We communicate with hospitals or trial teams to assess whether a case may be suitable for further screening.
We support appointment coordination, document submission, translation, and direct communication with international departments.
For international patients, we help with practical coordination — travel planning, hospital admission guidance, and local support.
If this option is not suitable, we help explore other relevant treatments, clinical trials, or advanced care pathways.
From inquiry through to follow-up, our coordinators provide a single point of contact for the family.
CancerFax does not guarantee treatment access, eligibility, or clinical outcome. Our role is to help patients access accurate information, structured review, and appropriate specialist pathways.
