FORT WORTH, Texas, Aug. 11, 2022 (GLOBE NEWSWIRE) -- TFF Pharmaceuticals, Inc. (NASDAQ: TFFP), 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 of 2022 and provided an update on recent corporate and clinical developments. The Company will discuss the highlights on a conference call and webcast, scheduled for today, Thursday, August 11, 2022, at 4:30 PM ET.

“We enter the second half of 2022 with significant momentum based upon the continued advancement of our internal pipeline coupled with growing recognition that our Thin Film Freezing technology has the potential to revolutionize drug delivery across a diverse array of molecules,” said Glenn Mattes, CEO of TFF Pharmaceuticals. “We have initiated Phase 2 studies for our two lead internal product candidates, Inhaled Voriconazole Powder (TFF VORI) and Inhaled Tacrolimus Powder (TFF TAC), and we are engaged in active outreach with a number of companies that have expressed interest in these two innovative programs. Importantly, the VORI and TAC programs also serve to further validate the clinical utility of Thin Film Freezing technology, sending a clear signal to the industry that applications of our technology continue to grow and advance further into human testing.

“Our partnering activity also remains robust, and we are now working with three additional top 20 pharma companies. With more than 20 disclosed collaborations and well over 50 material transfer agreements, we continue to make significant progress

with our industry and academic partners, consistently demonstrating how Thin Film Freezing offers a unique and versatile solution for significantly improving formulations for safer, more targeted drug delivery. We expect many of these programs to advance further into preclinical and clinical testing later this year. As the success of our partnerships continues to grow, we also anticipate that many of our existing partners will expand their relationship with TFF as well as open up the opportunity for developing new relationships.

“To accommodate current and future demand for Thin Film Freezing partnerships, in July we announced the opening of a new R&D facility located in Austin, Texas that provides us with significantly more laboratory space. This 3,500 square feet facility includes a dedicated lab for downstream processing of preclinical products created via Thin Film Freezing, which will complement the company’s existing formulation development capabilities. As TFF expands its in-house and partnered research, including applications in biologics, the Austin facility will also allow us to accommodate larger equipment to facilitate scale-up and manufacturing for preclinical studies.

“A major reason for our R&D expansion also relates to the increased feasibility work surrounding our next-generation vaccine programs. There is a growing body of scientific evidence suggesting that, when compared to conventional delivery, mucosal-based delivery of vaccines may reduce the burden of infectious diseases by providing first-line protection at viral entry points.1 We have successfully completed multiple feasibility studies with Thin Film Freezing demonstrating how our unique, dry powder-based formulations can be successfully delivered to both lung and nasal regions to elicit a robust host immune response. As this area of work continues to grow, we look forward to providing additional updates on our vaccine applications later this year.

“We have recently delivered the final published clinical study report for Inhaled Niclosamide Powder to our partner, UNION Therapeutics. Union is working diligently to provide TFF with feedback on their option to license Niclosamide Inhalation Powder. We continue to believe that the widespread availability of potent antiviral medicines is key to significantly lowering mortality and morbidity associated with COVID-19 infection.

“We believe the second half of the year is shaping up to be a very exciting period for TFF Pharmaceuticals. As a reminder, we spent the first half of 2022 positioning the company for significant growth by advancing our two lead pipeline assets into Phase 2 testing, forging important new strategic alliances, expanding the applications of our technology platform across a wide spectrum of molecules, and making key senior level appointments to help drive our growth while optimizing our capital and operational efficiencies. We look forward to announcing additional progress throughout the remainder of 2022.”

RecentClinicalandCorporateHighlights:

• In July, the Company announced a significant expansion of its R&D operations through the lease of a new research and development facility located in Austin, Texas. The new facility of over 3,500 square feet significantly increases TFF’s total lab space, adding a dedicated lab for downstream processing of products created via Thin Film Freezing, which will complement the company’s existing formulation development capabilities. The new space will be supervised by Donald Owens, Ph.D., Director of Product Development at TFF, and supported by John Koleng, Ph.D., R.Ph., Vice President of Product Development and Manufacturing. The company also plans to expand the product development team in Austin, which will be based at the new facility, to support the growing number of partnered projects.
  

StrategicBusinessDevelopmentandPartnershipActivities– Biopharmaceutical Companies and Research Institutions:

• In July, Dr. Bill Williams, co-inventor of the Thin Film Freezing technology, published an editorial review article in BiopharmInternational entitled, “Improved Formulations to Enable Stable Delivery of Biologics”. The article highlights the significant advantages of Thin Film Freezing over conventional freeze-drying processes, including improvements with respect to less particle aggregation and less protein denaturation, which can overcome challenges in the formulation and delivery of biologics.

• In May, the Company announced multiple presentations highlighting the broad applicability of its Thin Film Freezing Technology at the Respiratory Drug Delivery Meeting (RDD). Dr. Williams delivered a platform presentation with data on stabilizing and delivering antivirals, antibodies and vaccines using Thin Film Freezing technology in the fight against COVID-19 and other serious viral infections. Additionally, Dr. Williams and his colleagues presented five posters highlighting the broad applicability of Thin Film Freezing to improve drug development of biologics and small molecules for respiratory diseases, including pulmonary fibrosis and COVID-19. The findings from Dr. Williams’ lab also highlighted how Thin Film Freezing can be used to facilitate delivery of other treatment modalities, such as gene therapy.
  

• In April, the Company announced safety and pharmacokinetic data from its Phase 1 study of Niclosamide Inhalation Powder, which is being developed as a potential treatment for COVID-19. The data showed that Niclosamide Inhalation Powder was well tolerated with no serious adverse events across all subject cohorts. TFF Pharmaceuticals believes the 6 mg dose level of Niclosamide Inhalation Powder is estimated to produce a concentration of >100 µM in the epithelial lining fluid in the lung following delivery as a dry powder, which would be considered highly potent with respect to inhibiting viral replication. A single administration of 6 mg of Niclosamide Inhalation Powder to the lungs provided equal mean maximum drug concentration (Cmax) in the blood as 100 mg delivered as a nebulized spray to the lungs and nasal cavity, as demonstrated in a recent publication.2

ABOUTTFFPHARMACEUTICALS’THINFILMFREEZINGTECHNOLOGYPLATFORM
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 Thin Film Freezing 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 Thin Film Freezing can deliver as much as 75% of the dose to the deep lung. Thin Film Freezing 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 Thin Film Freezing can be used to enhance traditional delivery or combined to enable next-generation pharmaceutical products.
