FORT WORTH, Texas, Sept. 08, 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 announced that Dr. Bradley Gardiner of the Royal Alfred Hospital in Melbourne, Australia shared a podium presentation on the compassionate use of TFF’s Voriconazole Inhalation Powder (TFF VORI) as part of the 15th International Congress on Lung Transplantation, which is being held in Paris on September 8-9, 2022.

Presentation details are as follows:

Title: Inhaled voriconazole: an effective novel antifungal delivery method which reduces systemic absorption and toxicity
Date/Time: Thursday, September 8 at 10:49a.m. CET (4:49a.m. ET)
Presenter: Dr. Bradley Gardiner – Infectious Diseases Physician, Royal Alfred Hospital

TFF VORI is a next-generation, direct-to-lung, inhaled dry powder formulation of voriconazole for the treatment and prevention of Invasive Pulmonary Aspergillosis (IPA). TFF’s proprietary Thin Film Freezing technology platform allows the reformulation of voriconazole into a dry powder with properties ideally suited for inhalation. The inhaled formulation increases the local concentration of therapy in the lung, where it is needed most, potentially improving efficacy while also reducing systemic toxicities and drug-drug interactions seen with orally administered voriconazole. TFF previously announced data from its Phase 1b study of TFF VORI showing the therapy was well tolerated in asthma patients and could provide a differentiating benefit to a broad population of patients with IPA and other pulmonary fungal infections.

As part of TFF’s ongoing compassionate use program, a lung transplant patient with pulmonary fungal infections in Australia was treated with TFF VORI beginning in February 2022 and has continued on chronic daily therapy (80mg BID) for the past 6 months. This patient was not able to continue with oral voriconazole or other azole antifungals due to preexisting melanoma and significant toxicities when previously administered oral voriconazole. The patient had also been experiencing a meaningful loss of pulmonary function prior to initiation of the TFF VORI treatment. Notably, upon initiation of TFF VORI, the patient’s lung function stabilized without additional decreases in Forced Expiratory Volume in one second (FEV1) and with recovery in Forced Vital Capacity (FVC). The patient was able to tolerate inhaled voriconazole due to the limited systemic absorption compared to the oral administration route. Also, the patient tolerated TFF VORI without having to lower the dose of his tacrolimus immunosuppressant, which can have a severe drug-drug interaction with oral voriconazole. These results support the potential safety and efficacy advantages of TFF VORI, which TFF expects to further demonstrate in its ongoing Phase 2 study.

“Before treatment with TFF’s inhaled voriconazole, this patient was deteriorating with limited treatment options,” said Dr. Bradley Gardiner. “Following treatment with TFF VORI, he has stabilized and has not required hospitalization. These results are especially meaningful for patients who cannot tolerate oral voriconazole therapy due to other comorbidities such as skin cancers or upon experiencing one of the many well-known tolerance issues with oral antifungal therapies.”

“We are excited to share these data showcasing how inhaled voriconazole powder could present a safer alternative for patients compared to oral treatment, especially for those who have undergone lung transplant or have other conditions that require medications that are susceptible to the well-known drug-drug interactions of oral voriconazole,” said Dale Christensen, Ph.D., Head of Clinical Development at TFF Pharmaceuticals. “We are particularly encouraged by the clinical stability achieved for this patient, which supports our treatment hypothesis that inhaled voriconazole can be efficacious at lower doses and is well tolerated without the severe drug-drug interactions associated with oral voriconazole.”

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.


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.
