The Department of Health and Human Services, specifically the National Institutes of Health (NIH), intends to award a firm-fixed price contract for the procurement of five cases of Therakos Cellex USA Kits, essential for emergent Extracorporeal Photopheresis (ECP) procedures at the NIH Clinical Center in Bethesda, Maryland. These procedural kits are critical for patient care, particularly for those undergoing post-stem-cell transplant treatments, as they are the only compatible kits for the THERAKOS® CELLEX® Photopheresis System Instrument. Interested parties capable of providing similar products are encouraged to submit a capability statement by October 20, 2024, at noon EST, to Tasha Lowe at lowet2@mail.nih.gov, as the procurement will follow simplified acquisition procedures exempt from competitive requirements.
