FDA Provided Constructive Feedback to Help Guide Next Steps in TFF TAC Clinical Development

Company to Provide More Detailed Regulatory Update in 3Q 2024

FORT WORTH, Texas, June 24, 2024 (GLOBE NEWSWIRE) -- TFF Pharmaceuticals, Inc. (NASDAQ: TFFP) (“the Company”), a clinical-stage biopharmaceutical company focused on developing and commercializing innovative drug products based on its patented Thin Film Freezing (TFF) technology platform, today announced a regulatory update on the Company’s TFF TAC clinical program following its recent interaction with the U.S. Food and Drug Administration (FDA).

In April 2024, the Company submitted a briefing book to the FDA to help guide the next steps in the clinical development pathway for TFF TAC. Following its review of the briefing book, the FDA concurred that mitigation or prevention of tacrolimus associated toxicities without placing the lung allograft at risk will be an important therapeutic benefit and provided constructive feedback and valuable guidance on the roadmap for advancement of TFF TAC. Based on this feedback, the Company does not expect a significant change to either its timelines or the estimated costs associated with the clinical advancement of TFF TAC.

“The initial feedback from the FDA on the TFF TAC clinical program has provided us with additional clarity on how we can continue advancing this innovative product towards registrational testing,” said Dr. Zamaneh Mikhak, Chief Medical Officer of TFF Pharmaceuticals. “Over the next several weeks, we expect to receive additional guidance from the FDA, which should allow us to provide a more detailed regulatory update on the program in the third quarter of 2024.”

About TFF TAC
TFF TAC is an inhaled dry powder formulation of tacrolimus, a potent immunosuppressive drug. Oral tacrolimus is currently the first line calcineurin inhibitor used for prevention of rejection after solid organ transplantation but it is associated with many toxicities such as kidney toxicity, particularly when high doses are needed as is the case after lung transplantation.

TFF TAC delivers tacrolimus directly to the lung to yield improved lung immunosuppression at lower doses and systemic exposures compared to oral tacrolimus to improve efficacy and decrease systemic toxicities such as kidney toxicity. TFF TAC is delivered via an easy-to-use dry powder inhaler.

The ongoing Phase 2 trial of TFF TAC is an open-label study in lung transplant patients who require reduced tacrolimus blood levels due to kidney toxicity. Part A of the trial is a 12-week treatment period, and Part B is an optional safety extension period. Trial endpoints include safety and tolerability including kidney function, acute allograft rejection and pharmacokinetics.
