NeoStem's Subsidiary, Progenitor Cell Therapy LLC (

NEW YORK, Dec. 3, 2013 (GLOBE NEWSWIRE) -- NeoStem, Inc. (Nasdaq:NBS), and its subsidiary, Progenitor Cell Therapy, LLC ("PCT"), announced the expansion of PCT's relationship with ImmunoCellular Therapeutics, Ltd. ("ImmunoCellular") (NYSE MKT:IMUC), a clinical-stage company that is developing immune-based therapies for the treatment of brain and other cancers, for current good manufacturing practices (cGMP) and development services for ImmunoCellular's dendritic cell-based vaccines. PCT currently manufactures ICT-121, a dendritic cell vaccine targeting CD133 cells, in a Phase 1 clinical trial for recurrent glioblastoma multiforme (GBM) pursuant to a Services Agreement between the companies. PCT also manufactured Phase 2 clinical supplies of ICT-107, a dendritic cell-based vaccine targeting six tumor-associated antigens for newly diagnosed GBM. Under this newly executed Services Agreement, PCT will manufacture clinical supplies of ICT-140, a dendritic cell vaccine targeting seven ovarian cancer antigens, using process improvements PCT will develop that can be applied to the manufacture of all ImmunoCellular's current vaccine product candidates, ICT-107, ICT-121 and ICT-140. These process improvements are intended to increase quality, consistency, efficiency, and cost-effectiveness, and support ImmunoCellular's vaccine manufacturing requirements for conducting potential Phase 3 registration trials and for commercial manufacturing should these therapies receive Food and Drug Administration approval.

"Ensuring that ImmunoCellular has an established manufacturing process that can support pivotal registration programs and eventual commercial manufacturing for all our dendritic cell vaccines as they advance toward registration is foundational for building a leading cancer immunotherapy company," said Andrew Gengos, ImmunoCellular Chief Executive Officer. "We look forward to continuing our partnership with PCT, and are pleased to be making this investment in process enhancements now."

"We appreciate the opportunity to begin yet another project with ImmunoCellular as a manufacturing and development partner," said Robert A. Preti, PhD, President of PCT and Chief Scientific Officer of NeoStem. "PCT has developed significant expertise in the development and manufacture of dendritic cell vaccines, as well as other immunotherapies, over its 15 year history, including the experience of our long-term service for Dendreon for whom we provided manufacturing through pivotal studies of Provenge®, the first cell therapy approved for cancer treatment."
