Pegylated G-CSF

Australasian Gastro-Intestinal Trials Group · Phase 3 active Small molecule ✓ Verified May 2026

Pegylated G-CSF is a Growth factor Small molecule drug developed by Australasian Gastro-Intestinal Trials Group. It is currently in Phase 3 development for Reducing the incidence of infection in patients with non-myeloid malignancies receiving myelosuppressive chemotherapy, Reducing the incidence of infection in patients with acute myeloid leukemia. Also known as: Neulasta, Neulasta®), Pegfilgrastim, Pegfilgrastim 6 mg.

Pegylated G-CSF stimulates the production of white blood cells, specifically neutrophils, to help the body fight infection.

Pegylated G-CSF is used to treat conditions such as lymphoma, leukemia, and chemotherapy-induced neutropenia. It works by facilitating the transfer of carbon monoxide or oxygen, although its exact modality is unknown.

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

Mechanism of action

This is achieved by mimicking the action of the natural hormone G-CSF, which is responsible for regulating the production of neutrophils in the bone marrow. By increasing the production of neutrophils, pegylated G-CSF helps to reduce the risk of infection in patients undergoing chemotherapy or other treatments that suppress the immune system.
