Manufacturing Considerations for NeoStem’s Acquisition of California Stem Cell
Recently, NeoStem made the very exciting announcement that it has signed a definitive agreement to acquire California Stem Cell, Inc. (“CSC”) and with it, its innovative cancer immunotherapy Melapuldencel-T. This acquisition is significant to the company for a number of reasons, but, as the Chief Scientific Officer of NeoStem and the President of Progenitor Cell Therapy (“PCT”) I am personally excited to tell you how I see great synergy between this acquisition and our own manufacturing capabilities.
First, a bit about me, I have served on the Stem Cell Banking Committee and Cord Blood Subcommittee of the New York State Department of Health and on the New Jersey State Department of Health’s Blood Bank Advisory Committee, chairing the Hematopoietic Progenitor Cell Processing Subcommittee. In addition, I have served in a leadership capacity for many professional organizations, including treasurer and founding member of the International Society of Hematotherapy and Graft Engineering, now called ISCT (International Society for Cellular Therapy). I recently completed a five year term as a director for AABB, and am currently an Executive Committee member for the Alliance for Regenerative Medicine (ARM), where, among other activities, I co-chair the Standards and Technology Committee.
PCT, which I co-founded more than a decade ago, was originally built in response to a recognized need for high quality manufacturing and development services in an emerging industry. As the cell therapy field has grown, so too has PCT— the company has now served over 100 clients and performed more than 30,000 cell therapy procedures. Since PCT was acquired by NeoStem in 2011, we have found unique synergies and efficiencies in being a single company paving the way in this industry. As with the acquisition of PCT, NeoStem believes in seeking growth by way of strategic procurement and we have continued to remain opportunistic as the field matures and consolidation presents opportunities for those like us with the specialized knowledge base and expertise associated with this industry.
As part of our due diligence for this transaction, the NeoStem team, including representatives from our scientific, technical, manufacturing and quality teams, evaluated CSC’s entire manufacturing process as it has been developed over the years. We studied both the current and previous processes for generation of DC-TC (autologous dendritic cells pulsed with irradiated tumor cells) and have satisfied ourselves that improvements to the manufacturing process for the generation of the patient-specific cancer initiating cells used to load the dendritic cells and direct the immunotherapy towards the patients’ cells expressing that unique antigen profile both reduced the time to manufacture the cell line and significantly improved the success rate to generate the TC line for patients enrolled in the trial. CSC scientists and product development personnel recognized a few years ago the need to improve on the success rate of TC line generation, and we were pleased to conclude that they have overcome this limitation through enhancements in the tumor cell collection and handling, the transport media, and adaptations in the manufacturing process itself through the use of microsphere formation ahead of cell line expansion. Importantly, FDA has agreed that these changes have been implemented in a way that maintains comparability between the previous process and the current process.
Our diligence convinced me that CSC’s products and processes are a natural fit with NeoStem’s unique clinical, regulatory and manufacturing expertise. Here are just some of the reasons:
- Using PCT’s in-house manufacturing services for Melapuldencel-T allows for efficient and cost effective manufacturing at all stages of development, including for this late stage product candidate.
- PCT’s Engineering & Innovation Center, focusing on automation and cost reduction strategies, is expected to be valuable to advancing Melapuldencel-T through its Phase 3 clinical trial and beyond in a way that results in high product quality with a reasonable cost of goods over the commercial life of the product.
- PCT’s expertise will be invaluable as we have helped many clients in their development for immunotherapy products, including Provenge for which PCT performed the manufacturing process during the development process through BLA submission.
- PCT has in place the additional capabilities CSC will need for robust product manufacturing and logistics for a multi-center Phase 3 trial and cost effective production for commercial sales if the CSC product is approved.
- Additionally, NeoStem can leverage CSC’s expertise in immunotherapy and the capacity in Irvine, both infrastructural and human, to do additional manufacturing and/or development work to advance CSC’s (NeoStem’s once the acquisition is complete) platform technology as well as those of PCT’s client base.
I am excited to welcome CSC’s management and staff into our growing company, and look forward to integrating and moving ahead with Melapuldencel–T and other cancer immunotherapy products.
