SANTA MONICA, Calif., Nov. 16, 2018 /PRNewswire/ -- Auritec Pharmaceuticals, Inc. ("Auritec"), a drug delivery company, announced

today the completion of recruitment of its investigational product (SR-TAC), for the prophylaxis of organ transplant rejection. 

SR-TAC is a novel formulation of the commonly used immunosuppressive calcineurin inhibitor tacrolimus that is delivered

subcutaneously. The product is an application of Auritec's patented technology Plexis™, wherein microparticles are coated with biocompatible polymers to produce extended drug release at safe and therapeutic levels. 

Tacrolimus is currently administered as daily pills that are known to demonstrate substantial inter-and intrapatient variability, dose-related toxicity and sub-optimal patient compliance, each of which contributes to graft failure especially in adolescent patients. Auritec's SR-TAC formulation aims to minimize peaks and troughs and improved patient adherence that could lead to safer and more effective calcineurin inhibition. 

RTB-010 is a single-center, first-in-human study to assess the safety and pharmacokinetic (PK) profile of SRTAC, which will be administered as a single dose of 0.1 mg/kg by subcutaneous injection in eight healthy subjects between the ages of 18-45 years. Subjects will be followed for up to 60 days.  

"The results from this study will inform the long-term goal of this program, which is to provide an improved treatment modality for prophylaxis of organ (kidney, liver and heart) transplant rejection with the additional benefit of enhancing medication compliance. These improvements have the potential to mitigate both the personal and economic burden of this disease," said Auritec's CEO, Dr. Thomas Smith. "Subsequent trials could lead to a product that improves adherence and reduces toxicity in transplant recipients." 

The trial is registered on as NCT03626714. 

About Organ Transplantation Each year more than 100,000 solid organ transplants are performed worldwide, and it is estimated that between 250,000 and 500,000 people are living with solid organ transplants requiring immunosuppression. The market for immunosuppressive drugs is estimated at greater than $4 billion. Global annual sales of tacrolimus products total more than $2 billion. Of the major players in the anti-graft rejection market, none have a sustained release formulation of their product.

About SR-TAC SR-TAC is a first-in-class, sustained release, subcutaneous treatment for prophylaxis of organ transplant rejection. In SR-TAC, tacrolimus monohydrate (an immunosuppressive calcineurin inhibitor commonly used for prevention of transplant rejection in products such as Prograf®, Astagraf®) is coated with a biocompatible polymer to extend drug release. SR-TAC may also be used in the treatment of autoimmune diseases such as psoriasis.

The company was founded in 2002 by Thomas J. Smith MD, the developer of the Vitrasert® ganciclovir intravitreal implant which was approved by the FDA in 1995.
