NEUPOGEN (filgrastim)

Trial Activity: Stable 79 active trials
Oncology Approved 1991-02-20

Neupogen (filgrastim) is a leukocyte growth factor used to manage neutropenia and reduce the risk of infection in various clinical settings. It is primarily indicated for patients with nonmyeloid malignancies receiving myelosuppressive chemotherapy or undergoing bone marrow transplantation, as well as those with acute myeloid leukemia. Additionally, the drug is used to mobilize progenitor cells for collection and to treat patients with chronic hereditary neutropenia or acute exposure to myelosuppressive radiation.

How NEUPOGEN Works

Filgrastim acts as a colony-stimulating factor by binding to specific receptors on the surface of hematopoietic cells. This binding stimulates the production, maturation, and activation of neutrophils within the bone marrow. By regulating neutrophil progenitor proliferation and enhancing functions like phagocytosis, the drug increases the body's ability to fight infections while having minimal impact on other blood cell types.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
