-- Hana Biosciences (Nasdaq:HNAB), a biopharmaceutical company focused on strengthening the foundation of cancer care, today announced that it will be presenting data on three compounds utilizing its OPTISOME(tm) Nanoparticle Technology at the "Molecular Targets and Cancer Therapeutics" International Conference sponsored by the American Association for Cancer Research (AACR), the National Cancer Institute (NCI), and the European Organization for Research and Treatment of Cancer (EORTC) taking place October 22-26, 2007 at the Moscone Convention Center West in San Francisco, CA.
Hana will present the first clinical data related to vinorelbine Optisomes (Alocrest(tm)) in a poster presentation of Abstract #A150 titled "A phase 1 and pharmacokinetic (PK) study of vinorelbine liposomes injection in patients with advanced solid tumors, non-Hodgkin's lymphoma, and Hodgkin's disease" on Tuesday, October 23, 2007 from 12:30-2:30 p.m. and 5:30-7:30 p.m. PDT.
Hana Biosciences will also present nonclinical data related to each of the Optisome compounds during Poster Session C, Novel Drug Delivery Systems, on Thursday, October 25, 2007 from 12:30-2:30 p.m. and 5:30-7:30 p.m. PDT:
Abstract #C111 -- "Vincristine sulfate liposomes injection concentrates vincristine in tumor tissue and bone marrow of tumor-bearing mice."
Abstract #C109 -- "Vinorelbine liposomes injection results in greater tumor drug exposure compared to conventional vinorelbine in tumor-bearing nude mice."
Abstract #C11 -- "A pharmacokinetic study of a novel sphingomyelin/cholesterol liposomal topotecan and nonliposomal topotecan in rats."
About Alocrest(tm) (vinorelbine tartrate injection, OPTISOME(tm))
Alocrest is a novel sphingomyelin/cholesterol liposome-encapsulated vinorelbine formulation. Vinorelbine, a semi-synthetic vinca alkaloid, is a microtubule inhibitor that has been approved for use as a single agent or in combination with cisplatin for the first-line treatment of advanced non-small cell lung cancer. Vinorelbine is also widely used for the treatment of breast cancer. Preclinical comparison data with Alocrest demonstrates improved PK to include approximately two orders of magnitude increase in area under the curve, roughly a 10 fold increase in preferential accumulation in tumors, and an improved therapeutic index of 1.7-3.5 fold.
About OPTISOME(tm) Nanoparticle Technology
Optisomes are a new generation of unique sphingomyelin/cholesterol-based nanoparticles designed to encapsulate cell cycle-specific chemotherapeutics designed for improved efficacy with reduced toxicity. Optisomes are approximately 100 nanometers in diameter and able to encapsulate and transport cancer drugs preferentially to tumor sites. While too large to easily migrate out of normal blood vessels, Optisomes are able to migrate across the more "leaky" vasculature of a tumor, resulting in higher concentrations of drugs at tumor sites than in normal tissue. Optisomes' unique sphingomyelin-cholesterol composition is particularly well suited to cell cycle-specific agents such as vincristine, vinorelbine and topotecan. The relative rigidity of the Optisomes' outer shell results in a long circulating half-life and sustained drug release at the tumor site, which may increase tumor cell exposure during the most vulnerable phases of cell division. Combined, these factors are key to the Optisome advantage as sustained drug exposure increases tumor cell death. Hana's Optisome pipeline includes Marqibo(r) (vincristine), Alocrest(tm) (vinorelbine) and Optisomal topotecan.
