March 28, 2024 16:05 ET

FORT WORTH, Texas, March 28, 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 fourth quarter and full year 2023.

“Over the last several months, we have made significant progress showing that our Thin Film Freezing technology can be successfully applied, with both TFF TAC and TFF VORI demonstrating the potential to significantly improve the product profiles for two FDA-approved therapies,” said Harlan Weisman, M.D., Chief Executive Officer of TFF Pharmaceuticals. “As recently announced, we made the decision to prioritize the clinical development of TFF TAC, and we look forward to continuing work on this exciting program, along with evaluating strategic alternatives for the TFF VORI program. We also look forward to our Late-Breaking Abstract Presentation for TFF TAC at the 44th Annual International Society for Heart and Lung Transplantation (ISHLT) 2024 Meeting in mid-April 2024.”

Recent Clinical and Corporate Highlights:

  • On March 27, 2024, the Company hosted a conference call and webcast to present new data from the ongoing Phase 2 study of TFF TAC for the prevention of acute rejection in lung transplant, and from the Phase 2 study and the Expanded Access Program (EAP) of TFF VORI for the treatment of invasive pulmonary aspergillosis (IPA) infections.
    • For TFF TAC, the Company presented data showing that eight out of eight patients successfully transitioned from oral Tacrolimus to TFF TAC in the Phase 2 study. There has been no evidence of acute rejection, and four out of four patients who completed the 12-week treatment period of the study chose to remain on TFF TAC and proceed to the long-term extension of the trial. TFF TAC continues to demonstrate favorable safety results with no mortality or discontinuations due to adverse events.
    • For TFF VORI, a total of nine patients have enrolled between the Phase 2 study and the EAP. The Company continues to see positive efficacy results, as five of six patients who completed treatment achieved a clinical and mycologic response. Updated data from the Phase 2 study and Expanded Access Program demonstrate that TFF VORI continues to maintain an attractive safety profile with no IPA-related mortality or all-cause mortality.

  • In March 2024, the Company announced its intention to prioritize the TFF TAC program based on positive data from the ongoing Phase 2 study, the potential of the product to address a significant unmet need in lung transplant medicine, and the substantial market opportunity. With respect to TFF VORI, the Company announced that it would explore strategic alternatives, including partnering opportunities, collaborations, and government-based funding sources to support its continued development.
  • In January 2024, the Company presented data from the Phase 2 trial of TFF VORI at the Advances Against Aspergillosis & Mucormycosis (AAAM) Conference, which was held from January 25-27, 2024, in Milan, Italy. The data presented at the AAAM Conference were first disclosed by the Company in December 2023.
  • In the fourth quarter 2023, the Company announced the appointment of three new members of its Board of Directors, including Thomas B. King, Catherine Lee, J.D. and Michael Patane, Ph.D. All three members bring significant life sciences experience to their positions.

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.


TFF Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company engaging patented rapid freezing technology to develop and transform medicines into potent dry powder formulations for better efficacy, safety, and stability. The company’s versatile TFF technology platform has broad applicability to convert most any drug, including vaccines, small and large molecules, and biologics, into an elegant dry powder highly advantageous for inhalation, or for topical delivery to the eyes, nose and the skin. TFF Pharmaceuticals has two lead drug candidates in the clinic: TFF TAC (Tacrolimus Inhalation Powder) and TFF VORI (Voriconazole Inhalation Powder). The Company continues collaborations with a broad array of pharmaceutical companies, academic institutions, and government partners to revolutionize healthcare around the globe. The TFF Platform is protected by over 170 patents issued or pending in the U.S. and internationally.
