FORT WORTH, Texas, May 04, 2023 (GLOBE NEWSWIRE) -- TFF Pharmaceuticals, Inc. (NASDAQ: TFFP) (“the Company”), 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 it has entered into a Collaborative Research and Development Agreement (CRADA) with the National Institute of Environmental Health Sciences (NIEHS) to develop respirable, dry powder formulations of high molecular weight hyaluronan (HMW-HA) for treating or preventing respiratory diseases. Today’s agreement follows prior research which showed that HMW-HA formulated with Thin Film Freezing yielded dry powder formulations that possess desirable aerosol performance.

Under the terms of the agreement, NIEHS and TFFP will evaluate the pharmacokinetics and therapeutic efficacy of the TFF-HMW-HA formulations using in vitro and in vivo models of select respiratory diseases, with a primary focus on chronic obstructive pulmonary disorder (COPD) and viral respiratory diseases caused by SARS-CoV-2, influenza virus, and/or respiratory syncytial virus (RSV). Other indications may also be explored such as halogen-induced acute lung injury, acute and chronic lung allograft rejection, cystic fibrosis and asthma.

“Thin Film Freezing is a technology that possesses several advantages in engineering particles for various routes of administration, including for delivering drug to the lungs, which could hold significant potential for the treatment of numerous respiratory diseases,” said Harlan Weisman, M.D., Chief Executive Officer of TFF Pharmaceuticals. “Since 2020, TFF Pharmaceuticals has entered into multiple CRADAs with various U.S. government agencies that cover a broad range of applications, and today’s announcement with NIEHS is further recognition in Thin Film Freezing’s potential.”

"Delivering potentially life-saving medicine into the deep lung structures is essential towards improving clinical outcomes in respiratory disease,” said Dr. Anthony Hickey, Chief Scientific Officer of TFF Pharmaceuticals. “However, due to physical limitations, many commercialized drugs cannot sufficiently reach their intended target, leading to suboptimal efficacy. As a natural, high-viscosity mucopolysaccharide, we believe hyaluronan can be reformulated using Thin Film Freezing technology to reduce its viscosity and improve its solubility so that more drug can be delivered to the lungs.”

“As part of our commitment towards developing innovative respiratory medicines, we continually seek technologies that can aid the delivery of the medications we discover to the lungs,” said Dr. Stavros Garantziotis, Principal Investigator for the NIEHS. “Our preliminary results suggest that generation of hyaluronan powder via Thin Film Freezing has the potential to significantly improve upon current formulations of hyaluronan, which could have broad applications in the treatment of several respiratory diseases that are treatable by hyaluronan. We look forward to conducting preclinical studies to confirm our hypothesis.”

ABOUT TFF PHARMACEUTICALS’ THIN FILM FREEZING (TFF) TECHNOLOGY

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.
