Sunitinib 37.5 mg po once daily Capecitabine 1000 mg po twice daily

Sunitinib and capecitabine is a combination therapy pairing a multi-targeted tyrosine kinase inhibitor with a fluoropyrimidine chemotherapy agent, approved for advanced renal cell carcinoma and gastrointestinal stromal tumors. This dual-mechanism approach targets both tumor cell proliferation through kinase inhibition and DNA synthesis through chemotherapy, offering synergistic anti-tumor effects.

Mechanism of action

Sunitinib works by inhibiting multiple protein kinases that cancer cells depend on for survival and growth. These kinases control signaling pathways inside cancer cells and also regulate blood vessel formation that tumors need to grow. By blocking these kinases, sunitinib starves tumors of nutrients and signals needed for expansion, effectively slowing or stopping cancer cell proliferation. Capecitabine is a chemotherapy drug that gets converted into an active form once it enters cancer cells. This active form interferes with the cancer cell's ability to replicate its DNA and build the proteins needed for cell division. This directly damages cancer cells and prevents them from multiplying. When used together, these two drugs attack cancer through complementary pathways: sunitinib cuts off the tumor's growth signals and blood supply, while capecitabine directly poisons the cancer cell's DNA replication machinery. This combination approach can be more effective than either drug alone, particularly in advanced kidney cancers and certain gastrointestinal tumors that have become resistant to single-agent therapy.
