Conference call and live webcast scheduled today, Wednesday, March 10, 2021 at 4:30pm EST

AUSTIN, Texas--(BUSINESS WIRE)--$TFFP #earnings--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 full year ended December 31, 2020, as well as provided a business update on recent corporate and clinical developments. The Company will discuss the clinical, corporate and financial highlights on a conference call and live webcast, scheduled today, Wednesday, March 10, 2021 at 4:30pm EST.

“2020 was a remarkable year of accomplishment and building momentum for TFF Pharmaceuticals, due to success in achieving key milestones in our two-pronged business model of internal development of high-value, high-need therapeutics, combined with a focused and aggressive approach to seek out partners, licensees and collaborators for our breakthrough Thin Film Freezing platform technology,” said Glenn Mattes, President and CEO of TFF Pharmaceuticals.

“Our internal development programs are progressing ahead of expectations, as we are seeing very positive clinical results in both Phase 1 trials for our Voriconazole Inhalation Powder program, to treat the severe and life-threatening disease of Invasive Pulmonary Aspergillosis, as well as for our Tacrolimus dry-powder program for the prevention of lung transplant rejection.”

“Final data for our Voriconazole product, the first-ever clinical study of a direct-to-lung, Thin Film Freezing (TFF) dry-powder formulation, resulted in blood levels greater than two-fold higher than those shown to clear complex IPA infections, with no significant adverse events,” said Mattes. “And our Tacrolimus product was able to reach therapeutic blood levels of 5-16 ng/mL in all patients from a single inhaled dose of 5 mg of our reformulated Inhalation Powder, without significant adverse events. Both these very significant results bode well for our upcoming pivotal trials for these drugs, which address large markets with unmet needs.”

“We are also honored to announce today a strategically important contract for the Company with a major government research agency to formulate dry powder versions of a suite of biological countermeasures that is intended for use by our nation’s military forces,” continued Mattes. “This is another meaningful event for TFF as we continue to build our portfolio of development agreements with pharmaceutical companies, the government and academia. We look forward to providing more details on this contract pending security review and approval of further news distribution from the government and the prime contractor.”

“And our ubiquitous and disruptive Thin Film Freezing technology continues to garner considerable attention from potential industry partners,” said Mattes. “With the potential to mitigate the need for cold chain storage and distribution of vaccines, as well as the first-of-its-kind capability to reformulate large, complex biologic molecules, thin film freezing has generated strong interest from biotechnology companies, as well as some of the largest developers of vaccines and anti-virals.”

“This is evident by the recent feasibility collaborations by GreenLight Biosciences, a pioneering mRNA company, to reformulate their mRNA Covid-19 vaccine candidate, and by NeuroRx, to reformulate their product candidate, ZYESAMI, a therapeutic for seriously ill Covid-19 patients,” said Mattes. “The interest from these two companies, among many others, demonstrates the growing recognition that our technology can dramatically advance potential vaccines and therapeutics.”

“Our progress this year has firmly solidified the enormous potential on our Thin Film Freezing technology to the vaccine, biotechnology and drug development communities,” concluded Mattes. “The breakthrough and disruptive capabilities of our platform technology, and our ability to leverage this across both internal development programs and external business development opportunities has helped expand the depth of our business and will continue to fuel our future growth.”

Recent Clinical and Corporate Highlights:

• Voriconazole Inhalation Powder In March 2021, we announced the successful completion of the Phase 1 clinical trial and final data for Voriconazole Inhalation Powder for the treatment of invasive pulmonary aspergillosis (IPA), an inhaled dry powder version of voriconazole.
  
  Through completion of the Single Ascending Dose (SAD) and Multiple Ascending Dose (MAD) cohorts, TFF demonstrated that doses of 10, 20, 40, and 80 mg could be delivered twice daily using a dry powder inhaler device with no significant adverse events. There was no evidence of treatment-related or dose-related trends in the reporting of treatment emergent adverse events, throughout the study. No subjects experienced any dose limiting toxicity events during the study.
  
  Evaluation of the pharmacokinetic profile of the Voriconazole Inhalation Powder demonstrated that mean peak plasma voriconazole levels reached concentrations of 227 ng/mL following repeated dosing at 80 mg twice daily for 7 days, without any reports of significant adverse events. Based on the results of the Phase 1 trial, the Company will study the 80 mg dose of Voriconazole Inhalation Powder for the upcoming pivotal trial where it will be compared to the oral form of voriconazole.

• Tacrolimus Inhalation Powder: In March 2021, we also announced the successful dosing completion in the Single Ascending Dose portion of the Phase 1 study of Tacrolimus Inhalation Powder and that the Multiple Ascending Dose portion is progressing. The SAD portion of the study indicated that TFF’s Tacrolimus Inhalation Powder was able to reach therapeutic blood levels of 5-16 ng/mL in all patients from a single inhaled dose of 5 mg of Tacrolimus Inhalation Powder, without significant adverse events.
  
  The ability to reach therapeutic blood levels efficiently, with low doses of the inhaled powder, suggests that Tacrolimus Inhalation Powder may have application beyond lung transplant, potentially in heart, kidney and liver transplant patients.

• Strategic Business Development and Partnership Activities – Governmental and defense contracting agencies: TFF has been awarded a subcontract license by a U.S. government research agency to formulate dry powder versions of biologic countermeasures products to be used by the U.S. military. Our technology will be used to develop topical, ophthalmic and inhaled products, and as a result of this contract, TFF has been designated as an approved subcontractor vendor, which will facilitate additional work with the government. TFF will provide greater detail on the program pending security review approvals of further news distribution from the U.S. government and our prime contractor partner.
  
  In April of 2020, TFF Pharmaceuticals and USAMRIID, the U.S. Army’s premier institution and facility for defensive research into countermeasures against biological warfare, entered into a 3-year Cooperative Research and Development Agreement (CRADA) to investigate Thin Film Freeze Drying of various biodefense countermeasures as needle-free, inhaled treatments that are temperature-insensitive.
  
  The first two countermeasures, a monoclonal antibody (mAbs) against Ebolavirus Zaire (EBOV) and a recombinant vesicular stomatitis virus (rVSV) vaccine candidate against Venezuelan equine encephalitis virus (VEEV), were TFFD formulated and tested for efficacy in a well-established in vitro neutralization assay. Data showed that the activity of the mAbs and rVSV vaccines were preserved after TFFD. Formulation optimization and long-term stability testing are ongoing and our next steps will be in vivo testing in appropriate animal models.
  
  TFF continues to engage and collaborate with various government and defense contracting agencies in an effort to utilize the Company’s TFFD technology platform to formulate dry powder vaccines and therapeutics for delivery via reconstitution, or for lung or nasal inhalation.

• Strategic Business Development and Partnership Activities – Biopharmaceutical companies and research institutions: TFF recently announced a feasibility and material transfer agreement to evaluate a dry powder formulation of an early-stage Covid-19 mRNA vaccine candidate for Greenlight Biosciences. The goal of this feasibility work is to formulate and identify an optimal formulation of the Greenlight Biosciences mRNA product candidate in a dry powder form, which has superior stability as a dry powder, maintains the particle size of the mRNA, maintains a high encapsulation efficiency and has rapid reconstitution characteristics for injection.
  
  TFF also entered into a feasibility and material transfer agreement with NeuroRx to determine the compatibility of NeuroRx’s ZYESAMI™ (aviptadil, previously RLF-100™) as a dry powder formulation using TFF’s thin-film freezing technology. TFF intends to formulate and identify an optimal formulation of ZYESAMI in a dry powder form, with the goal of providing superior aerosol properties for delivery directly to the lungs. ZYESAMI is a recombinant form of a naturally occurring peptide found in the lung called Vasoactive Intestinal Peptide (VIP), which has been found to have potent anti-inflammatory/anti-cytokine activity in animal models of respiratory distress, acute lung injury, and inflammation. The ability to deliver this drug directly to the lung via inhalation could have important therapeutic implications and potentially broaden the application of the drug to patients less severely affected with Covid-19.
  
  In our worldwide licensing agreement with UNION Therapeutics for thin film freezing technology used in combination with niclosamide, our oral and powdered niclosamide formulations are moving forward to first-in-human trials.
  
  Our relationship with Felix Biotechnology is on track as we are working with their lead bacteriophage product for inhalation delivery directly to the lungs of patients. And our work with Augmenta Bioworks is on track as well. Our partnered lead monoclonal antibody product, targeting Covid-19 is scheduled to begin human trials later this year.
  
  In April of 2020, TFF and the University of Georgia’s Center for Vaccines and Immunology entered into a research and development agreement to test the immunogenicity and efficacy of universal influenza hemagglutinin (HA) recombinant vaccines following the TFF process. In late 2020, we announced positive preclinical immunogenicity and efficacy data from TFF formulated UGA universal Influenza HA recombinant vaccines. Animals were vaccinated with HA vaccines with or without adjuvants and challenged with H1N1 and H3N2 influenza viruses. The TFF HA vaccines elicited equivalent neutralizing antibodies and protection against influenza virus infection compared to liquid formulations.
  
  These results provide further evidence that Thin Film Freezing can convert liquid forms of vaccines that require cold chain storage into a much more stable dry powder form for ultimate use.
  
  TFF continues to engage with several leading multi-national pharma companies in an effort to enter into feasibility projects taking the partner’s product candidates, whether small molecule, large molecule, biologics, enzymes, antibodies, gene therapy, DNA derived therapy and/or vaccines, to utilize the Company’s Thin Film Freezing technology platform to deliver new and innovative products directly to the lung.

• CBD Development and Commercialization: Our partner in the cannabinoid space, PLUS Products, is now producing thin film freezing formulations of cannabinoids and is planning to launch a new product based on this technology toward the end of the second quarter of 2021.

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.
