Shiraz University of Medical Sciences · Phase 3 active Small molecule ✓ Verified May 2026

Vitamin D3 (Low dose) is a Vitamin D analog Small molecule drug developed by Shiraz University of Medical Sciences. It is currently in Phase 3 development for Rickets, Osteomalacia, Osteoporosis, Hypocalcemia. Also known as: cholecalciferol.

Vitamin D3 is a fat-soluble vitamin that plays a crucial role in maintaining strong bones, immune function, and overall health.

Vitamin D3, a low-dose supplement, has been studied in various clinical trials for conditions such as obesity, vitamin D deficiency, chronic pain syndrome, inflammatory response, and healthy individuals. The exact mechanism of action of Vitamin D3 is unknown, but it has been used as an intervention in studies examining its effects on insulin resistance and cardiovascular risk factors in obese adolescents.

Likelihood of approval
59.3% 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).
  • 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
NMPA CN 2030–2033 +2.3 yr
