Triastek has accomplished a first-in-human (FIH) examine for its third 3D printed drug product, T21, for the remedy of average to extreme ulcerative colitis (UC). Developed utilizing Triastek’s 3D Microstructure for Colon Concentrating on (3DμS-CT), T21 is designed to ship the drug on to the colon. That is the primary time the colon concentrating on platform has been verified in human trials.
In drugs, oral remedy is usually the popular technique of drug administration by sufferers resulting from its security, affected person compliance and avoidance of injections and associated ache, however the digestive surroundings and mucosal transport mechanisms throughout the gastrointestinal tract can differ considerably amongst people. Moreover, conventional approaches to creating oral drugs usually result in the discharge of the treatment in different components of the gastrointestinal system earlier than it reaches the colon. As such, it has traditionally been troublesome to realize exact supply of medication to particular areas within the gastrointestinal tract.
To resolve the issue of focused and exact supply of oral medicine to the gastrointestinal tract, Triastek independently developed its third 3D printed drug product, T21, an oral colon-targeted supply drug for average to extreme UC.
On November 18, 2022, T21 acquired clearance for its Investigational New Drug (IND) software from the US Meals and Drug Administration (FDA) via the 505 (b) (2) pathway. The unique drug is an oral Janus kinase (JAK) inhibitor referred to as tofacitinib. Following the approval of T21, Triastek launched a FIH examine in Q1 of 2023 to confirm the colon-targeting of T21 after oral administration. At current, T21 has accomplished the FIH examine, and imaging outcomes have confirmed that T21 tablets are exactly delivered to the goal web site – the colon – for drug launch.
Colon-targeted formulation platform for exact drug supply
Triastek’s R&D staff used the 3D Microstructure for Colon Concentrating on (3DμS-CT) to design a 3D printed prototype formulation with numerous combos of a number of launch management mechanisms to handle the consequences of time and pH, allowing a discount within the impression of particular person gastrointestinal variations on drug supply and to realize a extra exact supply to the colon area of the gastrointestinal tract.
The FIH-tested T21 pill consists of an enteric layer round a delay layer, each of which shield the drug core (containing lively substances) situated within the pill’s center. The pH-dependent enteric-coated layer maintains the intact total construction of the pill within the gastric surroundings. After the pill is handed via the pylorus to the small gut, the enteric-coated layer is quickly eroded, exposing the delay layer. The time-dependent delay layer continues to erode at a continuing price within the intestinal tract. Researchers management the erosion time by adjusting the thickness of the delay layer of pre-selected polymer materials (s). After the delay layer is totally eroded when getting into or throughout the ascending colon, the drug is absolutely launched out from the drug core to the colon goal.
T21 FIH three-dimensional construction
In an effort to help in evaluating this course of, Triastek researchers designed a novel imaging construction throughout the T21 3D printed drug pill in order that X-rays can be utilized to look at its transition timing and site within the gastrointestinal tract. This imaging construction aids in ascertaining whether or not the drug is efficiently launched to the goal colon web site.

Professor Xiaoling Li, Co-founder and Chief Scientific Officer of Triastek, stated: “The primary in human examine knowledge with T21 confirm the exact colon supply functionality of the MED course of, and this platform is poised to change into the novel drug supply system of selection for colon-targeted new merchandise with both native efficacy or systemic absorption. We hope to proceed showcasing how Triastek’s 3D printing processes can carry technical options to pharmaceutical firms for environment friendly product growth of optimized drug supply, finally resulting in the power to offer sufferers with extra clinically useful medicines.”
Triastek has developed a number of supply expertise platforms primarily based on Triastek’s 3D printing processes, together with:
- 3D Microstructure for Delayed Launch (3DμS-DR)
- 3D Microstructure for SolubilityEnhancement (3DμS-SE)
- 3D Microstructure for Colon Concentrating on (3DμS-CT)
- 3D Microstructure for Gastric Retention (3DμS-GR)
- 3D Microstructure for Oral Peptide (3DμS-OP)
By means of the versatile mixture of a number of three-dimensional construction designs, our supply expertise platforms had been constructed to resolve challenges round numerous scientific software eventualities. Realizing the synergy of varied drug launch behaviors and the discharge of various medicine of their goal areas, our suite of platforms brings limitless potentialities for the event of strong dosage kinds.
Triastek supply expertise
Triastek’s 3D printing processes overcome the constraints of conventional drug product growth and in addition open up a brand new path for the manufacturing of latest pharmaceutical merchandise. On the manufacturing aspect, Triastek developed steady manufacturing for the 3D printing of latest merchandise with 3D microstructure, which will be accomplished in a single steady course of from uncooked materials provide to packaging. The manufacturing line integrates Course of Analytical Expertise (PAT) and suggestions management expertise to understand the automated technique of oral strong formulations.
The continual manufacturing line can be extremely digital and clever. The central management room will be began with one button, and the whole manufacturing course of doesn’t require guide intervention. The modular design allows each flexibility and expandability in manufacturing, minimizing downtime and permitting for fast growth of capability. A number of workstations can print collaboratively to realize high-throughput manufacturing. The utmost annual manufacturing capability can attain 50 million models. Sooner or later, we plan to construct extra manufacturing traces and crops throughout geographies to extend our manufacturing capability.
