FDA Announces New Program to Help HCT/P Manufacturers
FDA announced a temporary new program to help manufacturers of human cells, tissues, and cellular and tissue-based products (HCT/Ps) obtain a rapid, preliminary, informal, non-binding assessment from FDA regarding how specific HCT/Ps are regulated. The program, the Tissue Reference Group (TRG) Rapid Inquiry Program (TRIP), went into effect June 12 and will operate until Dec. 31. Information on how to submit a TRIP request is available online.
FDA Announces Project to Assist Physicians Seeking Access to Unapproved Cancer Therapies
FDA’s Oncology Center of Excellence announced a new pilot program to assist oncology health care professionals in requesting access to unapproved therapies for patients with cancer. The project includes a call center — Project Facilitate — to serve as a single point of contact for FDA oncology staff to help physicians treating patients with cancer go through the process of submitting an Expanded Access request for an individual patient, including follow-up of patient outcomes. The pilot program includes a central office for oncology requests enabling FDA to follow up on individual requests and gather data. FDA can use this data to determine how the process is benefiting patients and health care professionals. FDA’s Expanded Access is relevant for providers who have a patient with a critical or serious disease or condition, to whom it provides access to an investigational medical product (drug, biologic or medical device) for treatment outside of clinical trials when there are no comparable or satisfactory alternative therapy options available. Additional information about this program is available online.
Antibody Conditioning Enables MHC-Mismatched Hematopoietic Stem Cell Transplants and Organ Graft Tolerance
George et al found in a murine model that pre-treatment with a combination of six monoclonal antibodies targeting CD47, T cells, NK cells, and HSCs followed by donor HSC transplantation enabled stable hematopoietic system reconstitution in recipients with mismatches at half (haploidentical) or all major histocompatibility complex (MHC) genes. This approach allowed tolerance to heart tissue from HSC donor strains in haploidentical recipients, showing potential applications for solid organ transplantation without immune suppression. If reproducible in humans, the research shows great promise for treating certain immune and blood disorders with allogeneic therapies and for increasing the number of organs available for patients requiring transplantations.
Leukocyte Composition Used in Manufacturing CAR T Cells Affects Cell Expansion and Product Composition
Autologous chimeric antigen receptor (CAR) T cells have shown promising clinical results for treating hematologic malignancies. While CAR T cells are in general clinically effective, for some patients, initial attempts to manufacture CAR T cells have failed. Elavia et al, using density cell gradient separation and anti-CD3 stimulation for CAR T-cell culture and expansion initiation, show that composition of leukocytes can affect cell expansion and the composition of CAR T cell products. Evaluating 51 CAR T cell products, they found reduced expansion when greater quantities of monocytes were present post-density gradient separation. Greater quantities of monocytes and RBCs were associated with a greater proportion of CD4+ cells, and greater quantities of neutrophils were associated with a greater proportion of CD8+ cells. Uniform or complete lymphocyte enrichment of peripheral blood mononuclear cells is necessary to improve the consistency of final CAR T cell products.
Mesenchymal Stromal Cell Homing: Mechanisms and Strategies for Improvement
Mesenchymal stromal cells (MSCs) have been widely investigated for their therapeutic potential in regenerative medicine, owing to their ability to home damaged tissue and serve as a reservoir of growth factors and regenerative molecules. Clinical applications of MSCs rely on these cells to migrate successfully to the desired tissue following their administration. A variety of strategies have been employed in the hope of improving this process. Ullah et al review the molecular mechanisms underlying MSC homing based on a multi-step model involving (1) initial tethering by selectins, (2) activation by cytokines, (3) arrest by integrins, (4) diapedesis or transmigration using matrix remodelers, and (5) extravascular migration toward chemokine gradients — further reviewing the various strategies that have been investigated for improving MSC homing including genetic modification, cell surface engineering, in vitro priming of MSCs, and ultrasound techniques.

Results of Joint AABB-ISCT Working Group to Be Presented in Complimentary Webinar
Human platelet lysate (hPL) is a human product that can be produced from outdated platelets, thus avoiding ethical, medical and animal welfare concerns. An increasing number of studies demonstrate that hPL promotes cell growth similarly to or even better than fetal bovine serum in specific cell types. A complimentary webinar, Gaps in the Knowledge of Human Platelet Lysate as a Cell Culture Supplement for Cell Therapy is scheduled for July 17, 12 noon ET. Jacques Galipeau, MD, and Karen Bieback, PhD, will provide an overview of hPL, identifying the gaps in information on how hPL is produced and tested and the barriers to its translational use in producing clinical grade cell therapy products. Bieback who served as leader of the joint AABB-ISCT working group’s human platelet lysate (hPL) project team, will present results from the working group. The hPL project team activity is part of a collaboration established between AABB and ISCT to develop projects of mutual interest to the two organizations. Lizette Caballero, BS, MT(ASCP), of the UCSF Medical Center and ISCT Co-Chair of the AABB-ISCT Joint Working Group, will be directing the session.
FDA Posts Resources for Regenerative Medicine
A list of FDA resources for regenerative medicine (RM) is available online. Topics include FDA’s framework for the regulation of RM products, the Agency’s Regenerative Medicine Advanced Therapy (RMAT) designations, guidances on the development of RM therapies, CBER standards development activities, CBER workshops, meetings and conferences, and webcasts.
Regenerative Medicine Standards Landscape Document Outlines Existing Standards
In consultation with the National Institute of Standards and Technology (NIST) and stakeholders, FDA is facilitating efforts to coordinate the development of standards for RM therapies. Nexight Group and the Standards Coordinating Body (SCB) are coordinating community efforts to develop standards for RM therapies. Nexight has utilized public workshops and webinars to help develop processes enabling the identification of needed standards and to facilitate the development of standards that will have a high impact on the quality and safety of RM therapies. Nexight published The Regenerative Medicine Standards Landscape, which outlines existing standards that apply to analytical testing, bioprocessing, product quality, and preclinical and clinical studies. FDA updates the document annually; it is available on the SCB website. A list of workshops supporting standards development can be found on the FDA website.
