Oxarol (MAXACALCITOL)

Phase 3 active Small molecule Under review Quality 36/100

Oxarol (generic name: MAXACALCITOL) is a maxacalcitol drug. It is currently in Phase 3 development for Pustular psoriasis.

Maxacalcitol works by binding to the Vitamin D3 receptor, which helps regulate skin cell growth and differentiation.

Oxarol, also known as Maxacalcitol, is a small molecule used in the treatment of Secondary Hyperparathyroidism, Chronic Kidney Disease on Hemodialysis, and Hemodialysis. It is administered in various doses, including 1.0 μg/day and 0.25 μg/day Alfacalcidol, and has been studied in clinical trials as a maintenance therapy after intravenous treatment.

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).
  • Immunology slight uplift +1.0pp
    Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.
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
MHRA GB 2029–2031 +0.7 yr
Health Canada CA 2029–2032 +0.9 yr
TGA AU 2029–2032 +1.2 yr
PMDA JP 2029–2032 +1.5 yr

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).

Estimate based on the BIO/Informa industry phase transition rates plus per-drug modifiers for therapeutic area, sponsor type, FDA designations, mechanism, and trial design.

Mechanism of action

Imagine your skin cells are like a row of houses. The Vitamin D3 receptor is like the city planner that decides how many houses to build and where to put them. Maxacalcitol is like a special instruction that tells the city planner to slow down the building process, which helps to reduce the severity of pustular psoriasis.
