MarqiboTreatment for Acute Lymphoblastic Leukemia
Update: Marqibo (vincristine sulfate liposome injection) Now FDA Approved - August 9, 2012
Tekmira Provides Update on Licensed Product Candidate, Marqibo
Vancouver, BC March 21, 2012— Tekmira Pharmaceuticals Corporation, a leading developer of RNA interference (RNAi) therapeutics, disclosed that its licensing partner, Talon Therapeutics, Inc., announced today that the Oncologic Drugs Advisory Committee voted 7 yes, 4 no, and 2 abstain that evidence from clinical studies supports a favorable benefit/risk assessment for use of Marqibo (vincristine sulfate liposomes injection) for the treatment of adult Philadelphia chromosome-negative (Ph-) acute lymphoblastic leukemia (ALL) in second or greater relapse or that has progressed following two or more lines of anti-leukemia therapy. The FDA decision date for Marqibo is May 13, 2012.
Marqibo is a liposomal formulation of the chemotherapy drug vincristine. Marqibo, along with two other liposomal chemotherapy products, Alocrest (liposomal formulation of the chemotherapy drug vinorelbine) and Brakiva (liposomal formulation of the chemotherapy drug topotecan), were licensed from Tekmira to Talon Therapeutics, Inc. (formerly Hana Biosciences) in 2006. Talon is now responsible for all future development of these products, and Tekmira is entitled to receive milestone and royalty payments based on the successful development and commercialization of these three product candidates.
“We are pleased that Talon’s Marqibo program received a positive recommendation from the Oncologic Drugs Advisory Committee, and we look forward to the FDA’s completion of its review by May 13, 2012,” said Dr. Mark J. Murray, Tekmira’s President and CEO.
The ODAC provides the FDA with independent expert advice and recommendations; however the final decision regarding approval is made by the FDA.
Marqibo is a novel, targeted Optisome™ encapsulated formulation product candidate of the FDA-approved anticancer drug vincristine. Talon has been developing Marqibo for the treatment of adult, Ph- ALL and adult aggressive NHL. Vincristine, a microtubule inhibitor, is FDA-approved for ALL and is widely used as a single agent and in combination regimens for treatment for hematologic malignancies such as lymphomas and leukemias. Marqibo is designed to provide prolonged circulation of the drug in the blood and accumulation at the tumor site. These characteristics are intended to increase the dose of vincristine delivered in a safe and effective manner. Talon's NDA seeking accelerated approval of Marqibo (vincristine sulfate liposomes injection) has been accepted for filing by the FDA. Marqibo will be reviewed by the FDA under Subpart H — Accelerated Approval of New Drugs for Serious or Life Threatening Illnesses, for the treatment of adult Philadelphia chromosome-negative (Ph-) acute lymphoblastic leukemia (ALL) in second or greater relapse or that has progressed following two or more lines of anti-leukemia therapy. The PDUFA date is May 13, 2012.
