FORTH WORTH, Texas, Aug. 14, 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 reported financial results for the second quarter 2024 and provided a corporate update.

“Over the last several months, we have amassed a growing body of positive safety, efficacy and confirmatory biomarker data from our Phase 2 program that points towards TFF TAC becoming a significant new advancement for the prevention of lung transplant rejection,” said Harlan Weisman, M.D., Chief Executive Officer of TFF Pharmaceuticals. “Given our current financial resources, we are continuing to evaluate a number of different strategies to advance the TFF TAC clinical program in the most efficient manner possible.”

Recent Clinical and Corporate Highlights:

  • The Company recently provided an update from the ongoing Phase 2 trial of Tacrolimus Inhalation Powder (TFF TAC) for the prevention of lung transplant rejection.

    • Patient enrollment has accelerated with 13 patients now enrolled

    • TFF TAC at ~20% of the oral tacrolimus dose prevented acute rejection and achieved >80% of the oral trough blood levels leading to diminished drug burden

    • 9 out of 9 (100%) patients who completed the 12-week treatment period with TFF TAC chose to remain on the therapy by proceeding to the long-term extension phase

    • PK data indicate that TFF TAC dosing results in reduced systemic variability of tacrolimus; the systemic tacrolimus trough to peak concentration swings that occur with oral tacrolimus are not present with TFF TAC, which is predicted to reduce the risk of organ rejection and systemic toxicities such as chronic kidney disease.

    • Confirmatory biomarker data also remain positive:

      • Updated biomarker data indicate a 6.5-fold reduction in the number of abnormally expressed rejection-related gene sets after 12 weeks of treatment with TFF TAC compared to oral tacrolimus. These data further suggest TFF TAC has the potential to provide sufficient immunosuppression to prevent rejection; there was a reduction in expression of rejection-related gene sets from 23% abnormal while on oral tacrolimus to only 3.6% abnormal after treatment with TFF TAC (an 85% reduction).

      • New biomarker data exploring the presence of donor-specific antibodies (DSA) are now available in the first 8 patients from the study. DSA is known to drive antibody-mediated rejection and is generated when there is insufficient immune suppression systemically allowing the formation of antibodies in the lymph nodes and the spleen against the transplanted (donor) organ. DSA was negative for the first 8 patients on oral tacrolimus, and DSA remained negative after 12 weeks of treatment with TFF TAC.

    • With respect to TFF TAC safety and tolerability, there has been no mortality. The majority of treatment emergent adverse events were Grade 2 (moderate) or lower with no bronchospasm or wheezing reported. Kidney function has been maintained.

    • One patient was transitioned to a dose of TFF TAC that was too low, which led to blood trough levels that were >50% below the protocol-specified minimum. This patient experienced signs of acute rejection (Grade A1, which is minimal severity based on histopathology). TFF TAC was discontinued as required by the protocol, and oral tacrolimus was resumed. The acute rejection episode has resolved.

    • TFF is finalizing the design of the next study with TFF TAC in close collaboration with clinical investigators and is in communication with regulatory authorities and plans to provide additional updates on the program including a regulatory update later in the fall.

  • In June 2024, the Company announced that it engaged Outcome Capital as a strategic advisor for the purpose of evaluating potential corporate partnerships and licensing opportunities.

  • In May 2024, the Company announced that the U.S. government will be advancing several next-generation medical countermeasures (MCMs) formulated with its Thin Film Freezing technology into advanced preclinical testing. TFF Pharmaceuticals is collaborating with Leidos, a leading Fortune 500 information technology, engineering and science solutions and services leader, to develop next-generation MCMs designed to protect military and healthcare personnel against future chemical and biological (CB) threats. The research is funded by the Defense Advanced Research Projects Agency (DARPA) under a contract through the Personalized Protective Biosystems (PPB) program.

  • In May 2024, the Company announced that, in collaboration with the Cleveland Clinic, TFF Pharmaceuticals is advancing multiple multivalent universal influenza vaccines to protect against seasonal and pandemic viruses into preclinical testing. The decision to advance the vaccine candidates into preclinical testing was based upon the successful completion of formulation testing with stability data on the combination of hemagglutinin (HA) antigens with four different adjuvants. Based on these data, three HA antigen/adjuvant candidate vaccines have been selected for testing in a pre-clinical model at Cleveland Clinic Florida.
