SPI-2012, Spectrum's third biological drug, is a long-acting Granulocyte- Colony Stimulating Factor (G-CSF) that utilizes Hanmi Pharmaceutical Co., Ltd. proprietary platform technology, LAPSCOVERY1.

G-CSF stimulates proliferation of granulocyte progenitors and subsequent production of neutrophils in the bone marrow. A recombinant form of G-CSF is used in appropriate cancer patients to accelerate recovery from neutropenia after chemotherapy, allowing higher-intensity treatment regimens to be given at full-dose and on schedule. Chemotherapy can cause myelosuppression and unacceptably low levels of white blood cells, making patients prone to infections, hospitalizations, and interruption of additional chemotherapy treatments.

Target Indications

  • Chemotherapy induced neutropenia

Route of Administration

  • Subcutaneous injection

Mode of Action

Binds to the G-CSF receptor expressed on granulocyte progenitors and stimulates their proliferation and subsequent maturation to functionally active neutrophils.


  • Overall, in the Phase 1 studies in healthy volunteers, it was concluded that SPI-2012 had an acceptable safety profile and increased white blood cell (WBC) and neutrophil counts in a pronounced and dose-dependent manner.
  • A Phase 2 multicenter, dose-ranging study that evaluated the effectiveness and safety of SPI-2012 relative to a fixed, standard dose of pegfilgrastim as a concurrent active control was initiated in 2013 in collaboration with Hanmi Pharmaceuticals.
  • Made decision to advance SPI-2012 to Phase 3 due to positive Phase 2 results in September 2014.
  • Currently pursuing Special Protocol Assessment (SPA) before initiating a non-inferiority Phase 3 study, which will be powered at over 90% to demonstrate non-inferiority and at 80% to demonstrate superiority to pegfilgrastim.
