Patient enrollment has accelerated, now with 13 patients enrolled in trial
TFF TAC at ~20% of the oral tacrolimus dose prevented acute rejection and achieved >80% of the previous oral trough blood levels — leading to diminished drug burden
9 out of 9 (100%) patients who completed the 12-week treatment chose to remain on TFF TAC by proceeding to the long-term extension Phase; 2 patients have been treated for over a year and 6 patients have been treated for more than 6 months
Observed a 6.5-fold reduction in the number of abnormally expressed rejection-related gene sets after treatment with TFF TAC
No production of donor-specific antibodies (DSA) after treatment with TFF TAC
FORT WORTH, Texas, Aug. 06, 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 provided an update from the Company’s ongoing Phase 2 trial of Tacrolimus Inhalation Powder (TFF TAC) for the prevention of lung transplant rejection.
“The growing body of data from the TFF TAC Phase 2 study continues to suggest that TFF TAC has transformative potential to advance the field of immunosuppressive therapy to prevent lung transplant rejection,” said Dr. Harlan Weisman, Chief Executive Officer of TFF Pharmaceuticals. “We are finalizing the design of the next study with TFF TAC in close collaboration with our clinical investigators and in communication with regulatory authorities and look forward to providing additional updates on the program including a regulatory update later in the fall.”
Clinical Trial Update
“As the number of patients treated in our Phase 2 study continues to grow, we are highly encouraged by the emerging positive product profile for TFF TAC,” said Dr. Zamaneh Mikhak, Chief Medical Officer of TFF Pharmaceuticals. “For this update, we showed the available new data related to DSA for the first eight patients in the study. This analysis indicates that no patients have developed DSA after transitioning from oral tacrolimus to TFF TAC, suggesting sufficient systemic immune suppression to inhibit production of potentially harmful antibodies despite the modest decrease in blood trough levels. In addition, our updated gene expression data from now 8 patients show a dramatic 6.5-fold reduction in the number of abnormally expressed rejection-related gene sets, suggesting that TFF TAC has the potential to impart sufficient levels of immunosuppression to prevent rejection.”
ABOUT TFF PHARMACEUTICALS’ THIN FILM FREEZING (TFF) TECHNOLOGY
TFF Pharmaceuticals’ proprietary Thin Film Freezing (TFF) technology allows for the transformation of both existing compounds and new chemical entities into dry powder formulations exhibiting unique characteristics and benefits. The TFF process is a particle engineering process designed to generate dry powder particles with advantageous properties for inhalation, as well as parenteral, nasal, oral, topical and ocular routes of administration. The process can be used to engineer powders for direct delivery to the site of need, circumventing challenges of systemic administration and leading to improved bioavailability, faster onset of action, and improved safety and efficacy. The ability to deliver therapies directly to the target organ, such as the lung, allows TFF powders to be administered at lower doses compared to oral drugs, reducing unwanted toxicities and side effects. Laboratory data suggests the aerodynamic properties of the powders created by TFF can deliver as much as 75% of the dose to the deep lung. TFF does not introduce heat, shear stress, or other forces that can damage more complex therapeutic components, such as fragile biologics, and instead enables the reformulation of these materials into easily stored and temperature-stable dry powders, making therapeutics and vaccines more accessible for distribution worldwide. The advantages of TFF can be used to enhance traditional delivery or combined to enable next-generation pharmaceutical products.
