Triastek, Inc. has received clearance for its Investigational New Drug (IND) application from the United States Food and Drug Administration (FDA) to initiate clinical studies of the 3D printed medicine, T21, a potential treatment for ulcerative colitis.\n\n\n\n“We are excited to receive IND clearance to begin clinical trials of this potentially transformative treatment for patients,” said Senping Cheng, founder and CEO of Triastek. \n\n\n\n“Delaying drug release and delivering oral dosage forms to the colon is challenging, so T21 offers a promising new option for patients by providing site-specific drug delivery and localized drug effect, mitigating potential side effects from systemic exposure. We look forward to advancing this treatment into the clinic and appreciate the FDA’s support.”\n\n\n\nT21 is a novel potential treatment capable of colon-targeted drug delivery. With a 3D dosage form design, T21 can reach the targeted colon segment of the GI tract, thus permitting use of a lower drug dose than the reference listed drug, which provides systemic exposure. \n\n\n\nMade possible by the 3D printing process, radio-imaging agents embedded in specific components of the dosage form were employed in early formulation development to evaluate and confirm the location of drug release in the GI tract. This novel process can be utilized in the development of future drugs targeted to specific segments of the GI tract to increase the efficiency and success rate of product development. The delayed-release, colon-targeted oral tablet technology platform can not only be used for developing small molecule drugs, but for peptide drugs as well.\n\n\n\nT21 is Triastek’s third product to receive IND clearance from the FDA, having received clearance for T19, for treating rheumatoid arthritis, and T20, for cardiovascular and clotting disorders.
