Fludarabine plus Cyclophosphamide

German CLL Study Group · Phase 3 active Small molecule Under review Quality 0/100

Fludarabine plus Cyclophosphamide is a Chemotherapy combination (purine analog + alkylating agent) Small molecule drug developed by German CLL Study Group. It is currently in Phase 3 development for Chronic lymphocytic leukemia (CLL), B-cell non-Hodgkin lymphoma.

Fludarabine and cyclophosphamide work together as a chemotherapy combination that damages cancer cell DNA and suppresses immune function to treat chronic lymphocytic leukemia.

Fludarabine is a small molecule inhibitor of the enzyme ribonucleoside-diphosphate reductase RR1. It is used in combination with Cyclophosphamide to treat various cancers, including Hepatocellular Carcinoma, Human Papillomavirus-Related Carcinomas, and others.

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)

Mechanism of action

Fludarabine is a purine analog that inhibits DNA synthesis and repair in lymphoid cells, while cyclophosphamide is an alkylating agent that cross-links DNA strands, causing cell death. Together, they create a synergistic cytotoxic effect against malignant B-lymphocytes in CLL. The combination also provides immunosuppression, which can be beneficial in autoimmune-mediated hematologic conditions.
