Abstract #TPS8116: Phase 1b/2a open-label, multiple-dose, dose-escalation study to evaluate the safety and tolerability of SNS01-T administered by intravenous infusion in patients with relapsed or refractory multiple myeloma. Dr. John Lust et al. the Mayo Clinic, Rochester, Minnesota

About SNS01-T

SNS01-T is a novel approach to cancer therapy that is designed to selectively trigger apoptosis in B-cell cancers such as multiple myeloma, and, mantle cell and diffuse large B-cell lymphomas. Senesco is the sponsor of a Phase 1b/2a open-label, multiple-dose, dose-escalation study which will evaluate the safety and tolerability of SNS01-T when administered by intravenous infusion to relapsed or refractory multiple myeloma patients. The study is actively enrolling patients at the Mayo Clinic in Rochester, MN, the University of Arkansas for Medical Sciences in Little Rock, and the Mary Babb Randolph Cancer Center in Morgantown, West Virginia. http://www.clinicaltrials.gov/ct2/show/NCT01435720?term=SNS01-T&rank=1

About Multiple Myeloma

Multiple myeloma is an incurable cancer of plasma cells, a type of white blood cell derived from B-lymphocytes, normally responsible for the production of antibodies, in which abnormal cells accumulate in the bone marrow leading to bone lesions and interfering with the production of normal blood cells. Senesco was previously granted orphan drug status for SNS01-T, the Company’s lead drug candidate for treatment of multiple myeloma.

About Senesco Technologies, Inc.

Senesco, a leader in eIF5A technology, is running a clinical study in multiple myeloma with its lead therapeutic candidate SNS01-T, which targets B-cell cancers by selectively inducing apoptosis by modulating eukaryotic, translation, initiation Factor 5A (eIF5A), which is believed to be an important regulator of cell growth and cell death. Accelerating apoptosis may have applications in treating cancer, while delaying apoptosis may have applications in treating certain inflammatory and ischemic diseases. Senesco has already partnered with leading-edge companies engaged in agricultural biotechnology and is entitled to earn research and development milestones and royalties if its gene-regulating platform technology is incorporated into its partners’ products.
