Calcium folinate (LV)

Multicenter Clinical Study Group of Osaka, Colorectal Cancer Treatment Group · Phase 3 active Small molecule ✓ Verified May 2026

Calcium folinate (LV) is a Reduced folate cofactor / Chemotherapy adjuvant Small molecule drug developed by Multicenter Clinical Study Group of Osaka, Colorectal Cancer Treatment Group. It is currently in Phase 3 development for Colorectal cancer (adjuvant and metastatic, in combination with 5-fluorouracil). Also known as: LV.

Calcium folinate is a reduced form of folic acid that enhances the activity of fluorouracil (5-FU) by stabilizing the binding of fluorodeoxymonophosphate to thymidylate synthase.

Calcium folinate (LV) is a small molecule used in the treatment of various cancers, including colorectal, gastrointestinal, biliary tract, and pancreatic cancers, as well as recurrent childhood acute lymphoblastic leukemia. The exact mechanism of action of calcium folinate is currently unknown.

Likelihood of approval
61.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr

Mechanism of action

Calcium folinate (leucovorin) acts as a cofactor that increases the cytotoxic effect of 5-FU chemotherapy by providing the necessary reduced folate cofactor for thymidylate synthase inhibition. This combination enhances DNA synthesis inhibition and improves the anti-tumor efficacy of 5-FU in colorectal cancer. It is commonly used as an adjunct to 5-FU-based chemotherapy regimens.
