Product Introduction:
Cazanat is a multi-targeted anti-cancer agent formulated to interfere with tumor growth and angiogenesis (formation of new blood vessels that feed tumors). Manufactured under stringent quality standards, it is available in tablet form in three strengths and is typically prescribed for advanced or metastatic cancers.
Uses:
Cazanat (Cabozantinib) is used in the treatment of:
-
Advanced Renal Cell Carcinoma (RCC)
-
Hepatocellular Carcinoma (HCC) after prior sorafenib treatment
-
Medullary Thyroid Cancer (MTC)
-
Advanced solid tumors with RET or MET mutations (off-label in some settings)
-
Bone metastases-related cancer pain (investigational)
-
Combination with immunotherapy agents in certain protocols
Storage Instructions:
-
Store at room temperature (15°C to 30°C)
-
Keep away from moisture, heat, and direct sunlight
-
Store in the original container with the lid tightly closed
-
Keep out of reach of children and pets
How It Works (Mechanism of Action):
Cabozantinib is a tyrosine kinase inhibitor that blocks the activity of multiple kinases including VEGFR, MET, AXL, and RET, which are involved in tumor angiogenesis, growth, and metastasis. By inhibiting these receptors, it suppresses tumor blood supply, stops cancer cell proliferation, and reduces tumor invasiveness.
