Spectrum Pharmaceuticals In-Licenses a Novel, Long-Acting GCSF Drug in U.S. Clinical Trials from Hanmi Pharmaceuticals

  • SPI-2012, Spectrum's Third Biological Drug, Is a Long-Acting GCSF That Utilizes Hanmi's Proprietary Platform Technology, LAPSCOVERY™;
  • SPI-2012 Could Have Potential Advantages for More Rapid and Profound Granulocyte Recovery in Patients with Chemotherapy Induced Neutropenia, A Multibillion Dollar Worldwide Market;
  • In a U.S. Based Phase 1 Study in Healthy Volunteers, SPI-2012 Demonstrated Activity Similar to Neulasta® (pegfilgrastim) at One-Third the Dose;
    • Spectrum Expects to Initiate Phase 2 Trials In Collaboration With Hanmi in 2012;
  • If SPI-2012 is Ultimately Commercialized, Spectrum Shall Own Worldwide Rights Except For Korea, China, and Japan.

HENDERSON, Nev.--(BUSINESS WIRE)-- Spectrum Pharmaceuticals (NasdaqGS: SPPI) announced that it has entered into a co-development and commercialization agreement with Hanmi Pharmaceutical Company for SPI-2012 (formerly known as "LAPS-GCSF"), a drug for the treatment of chemotherapy induced neutropenia based on Hanmi's proprietary LAPSCOVERY™ Technology.

Granulocyte colony-stimulating factor (GCSF) stimulates the production of white blood cells by the bone marrow. A recombinant form of GCSF 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. The worldwide market for GCSF-related drugs was over $5 billion in 2011.

LAPSCOVERY™ (Long Acting Protein/Peptide Discovery) is a platform technology that can be applied to various molecules including glycosylated proteins, modified or artificial peptides with unnatural amino acid sequences. LAPSCOVERY™ can select the optimal conjugation sites from the proteins or peptides to minimize the structural hindrance and maximize the pharmacological activity.

"We were very impressed by Hanmi's platform technology and are delighted to add SPI-2012, our third biologic drug, to our mid-stage pipeline," said Rajesh C. Shrotriya, MD, Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals. "Early evidence suggests that there could be advantages of SPI-2012 over currently approved therapies in increasing the rate and intensity of neutrophil recovery. We believe this agreement is consistent with our strategy of acquiring promising drug candidates at reasonable upfront and developmental costs, while maintaining significant economics for our shareholders in the long-term."

"Spectrum Pharmaceuticals has a proven history in in-licensing, developing and commercializing drugs. As a result, we expect this collaboration to help significantly advance SPI-2012 through the clinical and regulatory pathways, and commercial success," said Dr. Gwan-Sun Lee, Chief Executive Officer and President of Hanmi Pharmaceuticals.

About Hanmi Pharmaceuticals

Established in 1973, Hanmi Pharmaceutical has now become the 2nd largest Korean pharmaceutical company with sales up to $558 million in 2008. Hanmi Pharmaceutical was successful in developing competitive products through ‘First Generic → IMD (Incrementally Modified Drug) → New drug' Korean type R&D strategy. By investing the cash from this success into new product development, Hanmi was able to become a competitive pharmaceutical company in the global market. While other Korean pharmaceutical companies focused only on in-licensing products from foreign companies, Hanmi concentrated on developing domestic products through in-house API synthesis. This allowed Hanmi to be successful in developing the competitive modifying technology.
