Cyclophosphamide and steroids

Radboud University Medical Center · Phase 3 active Small molecule

Cyclophosphamide and steroids is a Alkylating agent + corticosteroid combination Small molecule drug developed by Radboud University Medical Center. It is currently in Phase 3 development for Autoimmune conditions (e.g., vasculitis, lupus nephritis), Hematologic malignancies, Severe systemic autoimmune diseases. Also known as: prednisolone, endoxan.

Cyclophosphamide is an alkylating chemotherapy agent that damages DNA to kill rapidly dividing cells, while steroids suppress immune responses and reduce inflammation.

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
MHRA GB 2029–2031 +0.7 yr
Health Canada CA 2029–2032 +0.9 yr

Mechanism of action

Cyclophosphamide works by cross-linking DNA strands, preventing cell division and inducing apoptosis in malignant and autoreactive cells. Steroids (typically corticosteroids) enhance this effect by suppressing T-cell and B-cell function, reducing inflammatory cytokine production, and providing immunosuppression. This combination is used to target both malignant proliferation and pathogenic immune responses in autoimmune and hematologic conditions.
