Fruquintinib, sold under the brand name Fruzaqla, is an anti-cancer medication used for the treatment of colorectal cancer. Fruquintinib is a kinase inhibitor. It is taken by mouth.
The most common adverse reactions include hypertension, palmar-plantar erythrodysesthesia, proteinuria, dysphonia, abdominal pain, diarrhea, and asthenia.
Fruquintinib was approved for medical use in the United States in November 2023.
Medical uses
Fruquintinib is indicated for adults with metastatic colorectal cancer who received prior fluoropyrimidine-, oxaliplatin-, and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if RAS wild-type and medically appropriate, an anti-EGFR therapy.
Pharmacology
The earlier generation small molecule VEGFR inhibitors, such as sunitinib,22 sorafenib,23 regorafenib24 and pazopanib25 suffer from poor kinome selectivity. In fact, many of them inhibit more than 10 kinases at similar potency.
Fruquintinib is a highly potent and selective VEGFR 1, 2, 3 inhibitor
Fruquintinib was found to inhibit VEGFR2 (KDR) with an IC50 of 25 nmol/L in the Z-lyte assay. The kinase selectivity of fruquintinib was evaluated against a panel of 253 kinases using [32p-ATP] incorporation assay by Upstate Biotechnology Inc. (UBI) (Fig. 1B). The results showed that fruquintinib inhibited VEGFR family member (VEGFR1, 2, 3) with IC50s of 33 nmol/L, 35 nmol/L and 0.5 nmol/L, respectively with weak inhibition of RET, FGFR-1 and c-kit kinases. No significant inhibition was found against all other kinases at 1 μmol/L
History
Efficacy was evaluated in FRESCO-2 (NCT04322539) and FRESCO (NCT02314819). FRESCO-2 (NCT04322539), an international, multicenter, randomized, double-blind, placebo-controlled trial, evaluated 691 participants with metastatic colorectal cancer who had disease progression during or after prior fluoropyrimidine-, oxaliplatin-, irinotecan-based chemotherapy, an anti-VEGF biological therapy an anti-EGFR biological therapy if RAS wild type, and at least one of trifluridine/tipiracil or regorafenib. FRESCO, a multicenter, placebo-controlled trial conducted in China, evaluated 416 participants with metastatic colorectal cancer who had disease progression during or after prior fluoropyrimidine-, oxaliplatin, and irinotecan-based chemotherapy.
Society and culture
Legal status
In April 2024, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Fruzaqla, intended for the treatment of people with previously treated metastatic colorectal cancer (mCRC). The applicant for this medicinal product is Takeda Pharmaceuticals International AG Ireland Branch. Fruzaqla was approved for medical use in the United States in June 2024.
