Conference Call and Webcast Scheduled Today, Thursday, March 24, 2022, at 4:30 PM ET

FORT WORTH, Texas, March 24, 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 fourth quarter and year-end December 31, 2021, 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, March 24, 2022, at 4:30 PM ET.

“The progress we have made in advancing our internal pipeline while expanding our partnered programs has positioned us for continued success in 2022,” said Glenn Mattes, CEO of TFF Pharmaceuticals. “Our two most advanced programs, Inhaled Tacrolimus and Voriconazole Powders, now have initiated Phase 2 studies based upon an impressive body of supportive clinical data. We expect an interim analysis in the second half of the year and will look to partner these assetsafter the release of these data. We believe the success of either program would not only advance the current standard of care in their respective indication but would also serve to unlock significant shareholder value for our investors.”

“We are also excited about the robust activity surrounding our partnered programs, which reflects a growing recognition of the potential of Thin Film Freezing technology to improve drug formulation and delivery. For example, we have partnered with Union Therapeutics to develop Inhaled Niclosamide Powder for the treatment of COVID-19 infection, and in February, TFF published new research indicating that inhaled niclosamide completely inhibited Omicron at a dose of only 1μM. In our view, this level of potency may allow us to deliver reduced doses of niclosamide directly to the lung without compromising its antiviral activity, which could lead to significant safety and tolerability advantages versus other therapies.”

“Our government and academic partnerships also continue to grow. This month, we announced a CRADA agreement with USAMRIID that will assess the immune response of a dry powder recombinant Vesicular Stomatitis Virus Severe Acute Respiratory Syndrome Coronavirus-2 Glycoprotein (TFFD-rVSV-SARS2-GP) vaccine formulated using TFF’s Thin Film Freezing technology. This is now our second CRARA agreement with USAMRIID and reflects our strategic focus to work with organizations who can provide world-class scientific talent and testing capabilities to help further validate our Thin Film Freezing technology platform.”

“It is also becoming increasingly clear that Thin Film Freezing’s ability to improve formulations across a broad range of molecular entities will likely lead to more strategic-based collaborations. On March 1st, Catalent and TFF Pharmaceuticals jointly announced a collaboration that will significantly expand our access to manufacturing capabilities and provide scalability for our Thin Film Freezing technology, while also affording us the opportunity to build a portfolio of technology licensing partnerships. We are very excited about this strategic collaboration with Catalent and believe it will provide us the opportunity to significantly expand the applications of our technology platform.”

“Today, I am also very pleased to announce the appointment of Brandi Roberts to our Board. With over two decades of financial management expertise within the life sciences sector, Brandi brings considerable talent and experience to our company and is joining us at an important time in our Company’s growth. We will clearly benefit from her insight and depth of knowledge, and I look forward to working with her.”

“I would also like to express my thanks to Dr. Brian Windsor, who is stepping down from his roles as Board member and CSO. Since our company’s founding, Brian has been instrumental in helping to bring Thin Film Freezing technology to so many of our partners and pipeline assets. Brian has clearly played a key role in the evolution of TFF Pharmaceuticals, and on behalf of the entire team at TFF Pharmaceuticals, we thank him for his many accomplishments and guidance, and we wish him the best in his future endeavors.”

“Today as well, we are very pleased to announce the appointment of Dr. Anthony Hickey as our new Chief Scientific Officer. Tony is an internationally recognized scientist who has published extensively in several areas related to our core technology, including pharmaceutical inhalation aerosols, pharmaceutical process engineering, particulate science, pharmaco-complexity and tuberculosis therapy.”

“I am thrilled to assume the role of Chief Scientific Officer with TFF Pharmaceuticals”, said Dr. Anthony Hickey. “As a member of the TFF’s Scientific Advisory Board, I have seen the tremendous progress Glenn and his team have made in bringing thin film freezing technology into the mainstream of advanced formulation development. As CSO, finding opportunities to bring this innovative technology to both industry and academia will be a key focus for me, and I look forward to working with the outstanding scientists at TFF to achieve this objective.”

Mr. Mattes continued, “In 2021, we demonstrated the successful application of our Thin Film Freezing technology through the generation of positive clinical data in our two lead candidates. We believe these data sets, along with expansion of testing activities for our numerous partners, all point to Thin Film Freezing’s potential as a viable, mainstream formulation technology with potential to fundamentally change drug delivery. In 2022, we plan to leverage the success from the prior year to further build momentum and growth across our business to help drive shareholder value.”

Recent Clinical and Corporate Highlights:

• Voriconazole Inhalation Powder (TFF VORI): In November, announced the completion of dosing in the Phase 1b clinical trial of Voriconazole Inhalation Powder (TFF VORI), a next-generation, direct-to-lung, inhaled dry powder version of voriconazole for the treatment and prevention of Invasive Pulmonary Aspergillosis (IPA) (NCT #04576325). This study assessed the safety and tolerability in two cohorts of eight patients with mild to moderate asthma, a population at high risk of developing IPA. Initial data from the study suggests that TFF VORI is well tolerated in asthma patients, supporting the Company’s progress to Phase 2 study in IPA patients.

  Voriconazole is recommended as the first line treatment for IPA according to the Infectious Disease Society (IDSA) - Practice Guidelines for the Diagnosis and Management of Aspergillosis (2016), but oral voriconazole is associated with significant drug-drug interactions and toxicities. Delivery of voriconazole directly to the lung may allow for a product that has greater efficacy than orally administered voriconazole and that has improved safety through reduced systemic toxicities and reduced drug-drug interactions.

  To date, observational data from this trial support the inclusion of patients that have hyperreactive airway disease comorbidities in the Phase 2 trial. This suggests TFF VORI also may have the potential to treat Allergic Bronchopulmonary Aspergillosis (ABPA), which impacts up to 2.5%¹ of asthma patients.

• Science Day Event: In December, TFF Pharmaceuticals hosted a virtual Science Day which featured a presentation by Carsten Schwarz, M.D., Director of the Cystic Fibrosis Center in Potsdam Germany, on the Company’s Inhaled Voriconazole Powder for the treatment of invasive pulmonary aspergillosis (IPA), and a presentation by Christopher Emig, Ph.D., President and CEO of Augmenta Bioworks, Inc., on inhaled AUG-3387 for COVID-19. A replay of this event can be found on the TFF Pharmaceuticals website under the Investors – Events Calendar.

ABOUT TFF PHARMACEUTICALS’ THIN FILM FREEZING TECHNOLOGY PLATFORM
TFF Pharmaceuticals’ Thin Film Freezing (TFF) platform was designed to improve the solubility and absorption of poorly water-soluble drugs and is particularly suited to generate dry powder particles with properties targeted for inhalation delivery, especially to the deep lung, an area of extreme interest in respiratory medicine. The TFF process results in a “Brittle Matrix Particle,” which possesses low bulk density, high surface area, and typically an amorphous morphology, allowing the particles to supersaturate when contacting the target site, such as lung tissue. Based upon laboratory experiments the aerodynamic properties of the particles are such that the portion of a drug deposited to the deep lung has the potential to reach as high as 75 percent.
