to Clinical Commercial and Clinical Healthcare

StemExpress Clinical Brochure

From Product Development to Clinical Commercial

The mission of StemExpress is to promote the exploration and advancement of life-saving therapies, from research and development to clinical commercialization. With vast expertise in the pre-clinical, clinical, and healthcare space, StemExpress knows the importance of moving projects through all phases while ensuring scalability within the healthcare realm. As more commercial therapies are moving to approval stages, the need for clinical-level partners to support these projects is at an all-time high. StemExpress can help support these clients and close the clinical loop in the drug discovery process through flexibility, experience, partnerships, cold chain logistics, and targeted donor recruitment at StemExpress’s 8 locations nationwide – supporting projects and improving patient outcomes around the globe.

Choosing a complete partner in clinical research starts with a reliable donor base - from demographic diversity and targeted recruitment to recallability and retention. StemExpress focuses on finding the right donors for a project, with customizable IRB consents and downstream protocols to fit the clients needs. Once a donor is fit to a project, StemExpress works diligently to ensure recallability, with expert donor retention strategies in place.



High quality source material for the process and development phase of research

For over a decade, StemExpress has led the way in supporting Allogeneic cellular therapies by supplying high quality source material for the process and development phases of research. Because these therapies have the potential to affect a considerable amount of people, the FDA has stringent guidelines for the procurement of donor blood and tissue samples. Our GTP tissue collections meet the rigorous FDA 21 CFR 1271 regulations, ensuring reliable cell collection, isolation, processing and storage. StemExpress also implements extensive donor screening, testing and GTP compliance in an effort to prevent the introduction and transmission of communicable diseases. We offer our clients vast resources, giving access to our 6 distinct donor pools. Our extensive network can provide immeasurable value, ensuring optimal donor selection for cellular material that is tailored to a specific project.

Closed System Cell Manipulation

The CliniMACS Prodigy ® distills a full-scale GMP laboratory into a single unit capable of performing cell isolations and manufacturing clinical products for pharmaceutical, therapeutic devices, allogeneic and autologous production. The closed system produces GMP cell isolations straight from apheresis without any exposure to external environmental contaminants, ensuring patient sample integrity is never compromised. Through this groundbreaking device, StemExpress can partner with clients to run samples and create a cell therapy product, alleviating the need for hospitals to house and operate cumbersome laboratory equipment. This closed system processing is approved by the FDA for clinical use - Miltenyi offers multiple isolation kits, or custom technology can be uploaded onto the device as needed for specific projects under research partner’s or hospital’s regulatory guideline compliance.
