Product Introduction:
Cabotres is an oral anti-cancer therapy formulated with Cabozantinib, a multikinase inhibitor. It is indicated for patients with advanced or metastatic cancer and offers an effective treatment option where first-line therapies may have failed. The drug is approved for use under strict oncological supervision.
Uses:
Cabotres is used to treat:
-
Advanced renal cell carcinoma (RCC)
-
Medullary thyroid cancer (MTC)
-
Hepatocellular carcinoma (HCC) (especially after sorafenib)
-
Differentiated thyroid cancer (DTC) (off-label)
-
Soft tissue sarcomas (in clinical trials/off-label use)
-
Other solid tumors where angiogenesis is a key driver (investigational)
Storage Instructions:
-
Store at room temperature (15°C to 30°C)
-
Keep in the original container, tightly closed

-
Keep out of reach of children and pets
How It Works (Mechanism of Action):
Cabozantinib is a tyrosine kinase inhibitor (TKI) that blocks several proteins (e.g., VEGFR, MET, RET) involved in cancer cell proliferation, metastasis, and angiogenesis. By inhibiting these kinases, it starves tumors of blood supply and inhibits growth signals, leading to cell death.
