TFF Pharmaceuticals Reports Second Quarter 2021 Financial Results and Provides Business Update
Additional Data Readouts and Initiation of Pivotal Trials for Inhaled Tacrolimus and Voriconazole Programs Expected in 2H 2021
Multiple Ascending Dose (MAD) Study Demonstrates Inhaled Tacrolimus Inhalation Powder Achieves Blood Levels Sufficient for Efficacious Immunosuppression
Partnerships with Pharma, Academic Institutions and Government Continue to Advance
Conference Call and Webcast Scheduled Today,
“As we advance both our internal programs and external partnerships,
“During this quarter, we announced data from a multiple ascending dosing study showing that our Inhaled Tacrolimus Powder has superior bioavailability as compared to the oral dosage form of tacrolimus, and that relatively low doses as compared to the oral dosage form were able to generate blood concentration levels of tacrolimus known to be sufficiently immunosuppressive in preventing organ rejection following lung transplants. Our toxicology studies demonstrated that the lung concentrations are three- to four-fold higher than blood concentrations and together these data suggest that we can achieve sufficient drug levels in the lung to prevent rejection, while at the same time, mitigating the potential for renal toxicity. We believe this improved pharmacokinetic profile could result in superior safety compared to the oral product without sacrificing efficacy.”
“We are also excited to announce significant advances on the partnering front. Most recently, TFF and its partner, Augmenta Bioworks, announced the selection of a lead monoclonal antibody, AUG-3387, which is being developed for the prevention and treatment of COVID-19 and, importantly, has been shown to effectively neutralize the Delta variant in in vitro studies. The relationship with Augmenta is a prime example of how our Company’s Thin Film Freezing technology can be applied to proprietary, biologic-based therapeutics addressing a large unmet medical need in public health. This remains a highly active area of collaboration and partnerships for our company, as we now have in place several programs focused on the application of our TFF technology to biologic drugs.”
Importantly, all of our pharmaceutical company partnerships continue to advance, which include collaborations with Union Therapeutics Felix Therapeutics, GreenLight Biosciences,
“Results in the second half should further advance preclinical and clinical progress on both internal and partnered programs as well as generate material new business development opportunities. We believe these anticipated results will reinforce the applicability of TFF's proprietary technology for the use in improving human health across a number of therapeutic areas.”
He continued, “As a result of our continued progress across these programs, we have also made key leadership appointments to support both our manufacturing operations and the expansion of our government/academic institution partnership team.
“I am also delighted to announce the formation of TFF’s
“In the second half of the year, TFF will build on these significant accomplishments as we move our internal programs into pivotal testing. On the business development front, we expect to advance our programs with existing partners, while signing new licensing transactions with pharmaceutical and biotechnology companies.”

Recent Clinical and Corporate Highlights:
- Voriconazole Inhalation Powder (TFF VORI): As noted on the first quarter update, TFF has successfully completed the first of two dosing cohorts in a Phase 1b reactive airway study, which is evaluating safe dosing of TFF VORI in asthma patients with hyperreactive airways. The safety profile for TFF VORI continues to look favorable, with no serious adverse events reported in these cohorts. Top-line data from the study is expected in the third quarter of 2021. The Company continues preparations for an end of Phase 1 meeting with the FDA, and anticipates this meeting will also be held in the third quarter, after the dosing in this Phase 1b reactive airway study is complete.
Earlier in the year, TFF 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). 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. The Company expects to initiate a pivotal trial of TFF VORI in the fourth quarter of 2021, which will be designed to assess efficacy for treating patients with IPA or for preventing infection in patients at high risk for developing IPA infections.
- Tacrolimus Inhalation Powder (TFF TAC): In July, the Company announced completion of enrollment and preliminary data from its Phase 1 trial of Tacrolimus Inhalation Powder (TFF TAC). In the Single Ascending Dose (SAD) phase of the trial, single doses of inhaled tacrolimus of 0.5 mg, 1.0 mg, 2.5 mg to 5.0 mg were administered to healthy subjects. In the subjects that received inhaled tacrolimus in the low dose group, the mean trough blood levels reached 1.1 ng/mL, while blood levels in the highest dose group reached 10.0 ng/mL. Following lung transplant, it is desirable for patients to achieve maintenance tacrolimus blood levels from 5-15 ng/mL to prevent acute allograft rejection.
In addition, when subjects received inhaled tacrolimus dosing at 2.5 mg while fasting or 30 minutes after a high-fat meal, there were no significant differences in systemic exposure demonstrating that delivery by inhalation was not associated with food effects in this cohort of subjects. By contrast, the rate and extent of absorption of tacrolimus is significantly decreased when tacrolimus is administered orally when taken with food, and this effect is most pronounced after a high-fat meal.
In the Multiple Ascending Dose (MAD) phase, repeated dosing of inhaled tacrolimus every 12 hours over 7 days demonstrated that subjects receiving doses of 0.5 mg twice daily and 1.0 mg twice daily achieved 12-hour trough steady state blood levels that averaged 6.8 and 14.9 ng/mL, respectively. Importantly, these data demonstrate that low dosing of Tacrolimus Inhalation Powder (0.5-1.0 mg) can achieve blood levels that are believed to be sufficient for efficacious immunosuppression.
TFF Pharmaceuticals expects to report top-line safety data in the third quarter of 2021 and believes the strong bioavailability data will enable initiation of a clinical trial in lung transplant patients in the second half of 2021. The Company expects that the dosing regimen for the study in lung transplantation will be tailored to potentially provide effective immunosuppression in the lung while reducing renal toxicities.
In June, TFF Pharma held a Science Day for investors, featuring key opinion leader (KOL) perspectives on Thin Film Freezing applications, with a focus on TFF Tacrolimus for lung transplant and TFF approaches to improving vaccines.
Deborah Jo Levine, M.D., from UT Health San Antonio, provided background on lung transplantation, the current toxicity limitation of oral tacrolimus for immunosuppression, and the potential improvements with an inhaled formulation of tacrolimus (TFF TAC). Kartik Chandran, Ph.D., from the Albert Einstein College of Medicine, discussed the benefits of using the TFF technology to create a dry powder pulmonary formulation for the rVSV vaccine against COVID-19. Ted Ross, Ph.D., from the University of Georgia, discussed his experience utilizing the TFF process for creating a universal influenza vaccine for pulmonary delivery and its potential benefit over the existing annual vaccination. TFF Pharma's management team also provided an update on its internal pipeline and several upcoming planned clinical data releases for TFF TAC and TFF VORI (treatment of invasive fungal infections). The event and its presentation materials can be found on the TFF corporate website.
- Strategic Business Development and Partnership Activities – Governmental and Defense Contracting Agencies: Early in the second quarter, TFF announced that it is was awarded a contract with Leidos to participate in the Personalized Protective Biosystems (PPB) Program to develop next-generation chemical and biological protection for
U.S.warfighters and stability operators. The PPB research program is overseen by the Defense Advanced Research Projects Agency (DARPA) and aims to develop an integrated system that simultaneously reduces protective equipment needs while increasing protection for the individual against existing and future chemical and biological (CB) threats. TFF Pharmaceuticals will utilize its Thin Film Freezing platform to formulate a series of countermeasures designed to neutralize chemical and biological agents at the site of vulnerable tissue barriers, including the skin, eyes and respiratory system.
We continue to engage and collaborate with various government and defense contracting agencies in an effort to utilize the Company’s TFF technology platform to formulate dry powder vaccines and therapeutics for delivery via reconstitution for lung or nasal inhalation. This includes our 3-year
Cooperative Researchand Development Agreement (CRADA) with the United States Army Medical Research Institute of Infectious Diseases(USAMRIID) for biodefense countermeasures, and our early-stage universal influenza work with the University of Georgia’s Center for Vaccines and Immunology, part of the NIH’s Collaborative Influenza Vaccine Innovation Centers (CIVICs).
- Strategic Business Development and Partnership Activities – Biopharmaceutical Companies and Research Institutions, Cannabis Development and Commercialization: During the second quarter,
TFF Pharmaceuticalsand its partner, Augmenta Bioworks, selected a lead monoclonal antibody candidate, AUG-3387, for COVID-19. More specifically, Augmenta and TFF Pharmaceuticals plan to develop AUG-3387 as an inhaled therapy for the treatment of COVID-19 disease in two types of individuals: (1) those already infected with SARS-CoV2 who are at high risk for severe disease but who have not yet been hospitalized, and (2) for the prevention of SARS-CoV2 infection for individuals who are at high-risk for severe disease.
In vitro preclinical testing has demonstrated that AUG-3387 effectively neutralizes SARS-CoV2 and has activity against all variant strains tested to date, including major COVID variants of concern: Alpha (B.1.1.7 ), Beta (B1.1.351), Gamma (P.1) and Kappa (B.1.617.1) and Delta (B.1.617.2). TFF and Augmenta have an ongoing commitment to monitor activity of AUG-3387 against emerging SARS-CoV-2 variants and will be completing in vivo preclinical efficacy studies in the coming weeks. Continued scale-up manufacturing of AUG-3387 continues, and the Companies expect completion of toxicology studies to enable human clinical trials in the months ahead.
TFF also continues to work with its partner, PLUS Products, to develop Thin Film Freezing versions of cannabinoid products. PLUS Products is currently conducting consumer testing of specific formulations.

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.
