Darbepoetin alpha

Barts & The London NHS Trust · Phase 3 active Small molecule Under review Quality 0/100

Darbepoetin alpha is a Erythropoiesis-stimulating agent (ESA) Small molecule drug developed by Barts & The London NHS Trust. It is currently in Phase 3 development for Anemia associated with chronic kidney disease, Anemia in patients with non-myeloid malignancies receiving chemotherapy, Anemia of chronic disease. Also known as: Aranesp.

Darbepoetin alpha is an erythropoiesis-stimulating agent that binds to the erythropoietin receptor to stimulate red blood cell production.

Darbepoetin alpha is a protein-based erythropoietin receptor agonist used to treat various conditions, including anemia of chronic kidney disease and anemia. It works by stimulating the erythropoietin receptor to promote the production of red blood cells.

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

Darbepoetin alpha is a recombinant human erythropoietin analog with a longer half-life than epoetin alfa due to additional carbohydrate chains. It binds to erythropoietin receptors on erythroid progenitor cells in the bone marrow, promoting their proliferation, differentiation, and maturation into mature red blood cells. This mechanism increases hemoglobin levels and reduces the need for blood transfusions in patients with anemia.
