FDA-approved medications for colon and rectal cancer consisting of both generic and brand names

FDA-approved individual drugs (CRC)Mechanism of action
IpilimumabPrevent inhibition of T-cell mediated immune responses to tumors by binding CTLA-4
Bevacizumab (Mvasi)Mvasi, a mAb, inactivates serum VEGF treating metastatic CRC
PembrolizumabBinds to PD-1 inhibiting its interaction with PD-L1 and PD-L2. Enhances anti-tumor immune response and tumor immune monitoring
TucatinibInhibits HER-2 suppressing tumors by affecting cell proliferation and AKT and MAPK signaling
Ziv-aflibercept (Zaltrap)Inhibits VEGF-A and PIGF to reduce vascular permeability and inhibit neovascularization. Delay vision loss and advancement of metastatic CRC
Irinotecan hydrochlorideRestricts DNA strands from elegating by attaching to the topoisomerase I-DNA complex and inhibiting its action, which causes fatal double-stranded splits in the DNA. Causes apoptosis as DNA damage is ineffectively repaired
NivolumabRestores tumor-specific T-cell response in patients. Binds to PD-1, avert PD-L1 and PD-L2 from blocking the action of T-cells
RamucirumabBy binding to VEGFR2, it halts the ligands (VEGF-A, VEGF-C, and VEGF-D) from binding to it, blocking VEGF-stimulated receptor phosphorylation and the proliferation, permeability, and migration of human endothelial cells that are later caused by ligands
CetuximabBlocks the binding of EGF, which in turn prevents EGFR activation. It also binds selectively to the EGFR and phosphorylates and activates receptor-associated kinases (MAPK, PI3K/AKT, and JAK/STAT)
RegorafenibAt clinically attained concentrations it inhibits the function of VEGFR1, VEGFR2, VEGFR3, RET, PDGFR-alpha, PDGFR-beta, KIT, FGFR1, FGFR2, BRAFV600E, PTK5, TIE2, TrkA, RAF-1, BRAF, DDR2, SAPK2, Eph2A, and Abl
PanitumumabPanitumumab binds primarily to EGFR and prevents ligands from binding to EGFR
Leucovorin calciumBy strengthening the bond between the active metabolite (5-FdUMP) and the enzyme thymidylate synthetase, leucovorin increases the action of fluorouracil
