• Registrational, randomized, active-controlled Phase 3 study (ADVANCE) will study SPI-2012 as a treatment for chemotherapy-induced neutropenia in approximately 580 patients with breast cancer.
  • The company expects to start the pivotal trial soon and plans to complete enrollment in 2017.
  • SPI-2012 is a novel, long-acting granuloctye colony-stimulating factor (G-CSF) that utilizes a proprietary platform technology to maximize the pharmacological activity of G-CSF, resulting in increased potency and a prolonged half-life.
  • The worldwide commercial opportunity for the treatment of chemotherapy-induced neutropenia is over $6 billion.

HENDERSON, NV, USA I December 16, 2015 I Spectrum Pharmaceuticals, Inc. (NasdaqGS: SPPI), a biotechnology company with fully integrated commercial and drug development operations, and a primary focus in Hematology and Oncology, announced today that the company has reached agreement with the U.S. Food and Drug Administration (FDA) on the Special Protocol Assessment (SPA) for the Phase 3 clinical trial of its novel, long-acting G-CSF, SPI-2012 (eflapegrastim). This trial will evaluate the safety and efficacy of SPI-2012 as a treatment for chemotherapy-induced neutropenia in patients with breast cancer, and will serve as the basis for the Biologics License Application (BLA) filing.

“We are excited to have reached agreement with the FDA on the SPI-2012 SPA, which is the highest priority program at Spectrum,” said Rajesh C. Shrotriya, MD, Chairman and Chief Executive Officer of Spectrum Pharmaceuticals. “SPI-2012 is a novel proprietary biologic that has been shown in a Phase 2 clinical trial to be more potent than pegfilgrastim, and consists of a novel, recombinant G-CSF conjugated, using a technology that enhances the half-life of this therapeutic protein. Our team has been ready to start this registrational Phase 3 trial, and plans to aggressively drive study enrollment. Spectrum has built a strong clinical team and commercial infrastructure with expertise in the treatment of neutropenia. If approved, we believe this drug will enable us to compete in a blockbuster market and change the face of our Company.”

In accordance with the SPA, this registrational, Phase 3 trial, or ADVANCE study (RAnDomized Trial of SPI-2012 Versus Pegfilgrastim in the Management of Chemotherapy Induced Neutropenia in Breast CANCEr Patients Receiving Docetaxel and Cyclophosphamide) will be a multicenter, randomized, active controlled trial that will enroll 580 newly diagnosed early-stage breast cancer patients, who will receive adjuvant or neoadjuvant chemotherapy every 21 days. Adjuvant chemotherapy is treatment given after primary surgical therapy to kill any remaining cancer cells and increase the chance of long-term disease-free survival; neoadjuvant chemotherapy is the administration of cytotoxic agents before surgical resection in early-stage breast cancer to shrink the tumor and potentially allow for breast-conserving surgery. SPI-2012 will be administered subcutaneously as a fixed dose equivalent to 3.6 mg of GCSF, which was selected based on the robust pharmacological and pharmacodynamic data from Phase 2. The primary study endpoint is the Duration of Severe Neutropenia (Absolute Neutrophil Counts [ANC] <0.5×109/L) in Cycle 1 of chemotherapy, based on central laboratory assessment of ANC over the 21 day cycle. Secondary endpoints include the Incidence of Neutropenic Complications, Incidence of Febrile Neutropenia, Relative Dose Intensity, and safety.

About Special Protocol Assessments

A Special Protocol Assessment is a written agreement between a Sponsor and the U.S. Food and Drug Administration on the design, execution and analysis for a clinical trial that may form the basis of a new Biologics License application or BLA. Final marketing approval depends upon the efficacy results, safety profile and an evaluation of the risk/benefit of treatment demonstrated in the Phase 3 clinical program.

About Breast Cancer

According to the American Cancer Society (ACS), breast cancer is the second most common form of cancer in women after skin cancer, and the second highest cause of female cancer deaths after lung cancer. Unfortunately, it is estimated that about 1 in 8 (12%) of women in the US will develop invasive breast cancer during their lifetime. In 2015 in the United States (US), an estimated 231,840 new cases of invasive breast cancer and 60,290 additional cases of in situ breast cancer will be diagnosed, and approximately 40,290 US women are expected to die from breast cancer. In addition, ~2,350 men are also expected to be diagnosed with breast cancer in 2015 with an estimated 440 deaths.
