Foretinib
Foretinib is an investigational small-molecule tyrosine kinase inhibitor that has been explored for its potential in treating various types of cancer. Its unique mechanism of action targets multiple pathways involved in tumor growth and progression.

Key Takeaways
- Foretinib is an investigational multi-kinase inhibitor studied for its anti-cancer properties.
- It primarily targets receptor tyrosine kinases like MET, VEGFR2, RET, KIT, and FLT3.
- Clinical trials have explored its efficacy in cancers such as papillary renal cell carcinoma and medullary thyroid cancer.
- Its mechanism involves blocking key signaling pathways that promote cell proliferation and angiogenesis.
- Common side effects include gastrointestinal issues, fatigue, and hypertension, requiring careful management.
What is Foretinib and Its Therapeutic Uses
Foretinib is an orally administered, investigational multi-kinase inhibitor. It belongs to a class of drugs designed to block the activity of specific enzymes, known as tyrosine kinases, which play critical roles in cell growth, division, and survival. As a targeted therapy, it aims to interfere with the molecular pathways that drive cancer development.
Foretinib has been investigated in clinical trials for its potential therapeutic uses in several advanced or metastatic cancers. These include papillary renal cell carcinoma (PRCC), medullary thyroid cancer (MTC), and hepatocellular carcinoma (HCC). While it has shown promise in certain settings, its development status means it is not broadly approved for clinical use, and its applications are primarily within research and specific trial protocols. For instance, early studies suggested activity in patients with hereditary papillary renal cell carcinoma, a rare kidney cancer.
Foretinib: Mechanism of Action and Key Drug Information
The Foretinib mechanism of action involves the potent inhibition of several receptor tyrosine kinases (RTKs) that are frequently overactive in various cancers. Key targets include the mesenchymal-epithelial transition (MET) factor, vascular endothelial growth factor receptor 2 (VEGFR2), rearranged during transfection (RET), KIT, and FMS-like tyrosine kinase 3 (FLT3). By blocking these receptors, Foretinib disrupts downstream signaling pathways that are crucial for tumor cell proliferation, survival, angiogenesis (new blood vessel formation), and metastasis. This multi-targeted approach aims to inhibit cancer growth from several angles.
As part of its Foretinib drug information, it is important to note that it is administered orally, typically as a capsule or tablet. Its pharmacokinetic profile indicates that it is absorbed and metabolized in the body, with a half-life that supports once-daily dosing in many study protocols. Patients undergoing treatment with Foretinib are closely monitored for efficacy and potential adverse events, reflecting its investigational nature. The specific formulation and administration details are determined by the clinical trial protocol or research setting.
Foretinib Side Effects and Dosage Guidelines
Like many targeted therapies, Foretinib side effects and dosage considerations are crucial for patient management. Common adverse events reported in clinical trials often involve the gastrointestinal system, including diarrhea, nausea, and vomiting. Other frequently observed side effects include fatigue, hypertension (high blood pressure), palmar-plantar erythrodysesthesia (hand-foot syndrome), and proteinuria. Less common but serious side effects can include hemorrhage, gastrointestinal perforation, and thrombotic events.
The dosage of Foretinib is typically determined by the specific clinical trial protocol and the patient’s individual response and tolerability. It is often initiated at a specific dose, which may be adjusted based on the severity of side effects. Patients usually receive Foretinib orally once daily. Close medical supervision is essential to manage potential adverse reactions and ensure patient safety.
Potential side effects of Foretinib include:
- Gastrointestinal disturbances (diarrhea, nausea, vomiting)
- Fatigue and asthenia
- Hypertension (high blood pressure)
- Palmar-plantar erythrodysesthesia (hand-foot syndrome)
- Proteinuria (protein in urine)
- Mucositis
