Data Shows AUG-3387 Neutralizes SARS-CoV-2 Delta Variant in Infective Assays

Supports Earlier Data Showing AUG-3387 Binds Strongly to Delta Variant in Addition to Wild-Type Spike Protein and Other Variants of Concern

Catalent Selected as Contract Drug Manufacturing Organization (CDMO) for AUG-3387

Scale-up Manufacturing for AUG-3387 Proceeding Rapidly; Early Batches Show Promising Results

MENLO PARK, CA and AUSTIN, TX, USA I July 29, 2021 I Augmenta Bioworks, a biotechnology company enabling breakthroughs in medicine through immune profiling, and 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 positive in vitro data indicating that their lead anti-COVID-19 monoclonal antibody (“mAb”) therapy, AUG-3387, binds to and neutralizes the SARS-CoV-2 Delta variant (B.1.617.2). The Delta variant is the current dominant strain of SARS-CoV-2 in the U.S., Europe and other geographic regions around the world.

Recent data indicates that the Delta variant, which was recently declared a “Variant of Concern” by the World Health Organization, is more transmissible than the wild-type SARS-CoV-2 strain and other variants. The Delta variant now accounts for 83% of new cases in the U.S., according to recent CDC data. Demonstration that AUG-3387 effectively neutralizes the Delta variant in vitro is an encouraging step towards developing the therapy to slow and prevent ongoing spread of COVID-19.

“We are very excited about these new data, which reinforce our view that AUG-3387 could represent an important new class of biologic-based treatment modalities that can effectively target the emerging and potentially more pathogenic variants of the SARS-CoV-2 virus,” stated Dr. Christopher Emig, Chief Executive Officer of Augmenta Bioworks. “As global health officials look for innovative solutions to help curb human-to human spread of coronaviruses, we expect the treatment landscape for COVID-19 to evolve so that scalable, biologic-based therapies can play a more prominent role in efficiently combating viral transmission, particularly with respect to new, more infectious COVID-19 variants.”

Glenn Mattes, Chief Executive Officer of TFF Pharmaceuticals, added, “The rapid progress we are making with respect to generating positive in vitro data speaks to the enthusiasm both TFF and Augmenta have for evaluating the potential of AUG-3387 to combat all prevalent forms of the SARS-CoV-2 virus. Our collaboration also demonstrates how combining two highly innovative and complementary technology platforms can accelerate rapid advancements in drug development to address severe threats to global public health. We look forward to reporting further updates on the AUG-3387 program later this year.”

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-CoV-2 who are at a high risk for severe disease but who have not yet been hospitalized, and (2) for the prevention of SARS-CoV-2 infection for individuals who are at a high risk for severe disease.

The companies have selected a final formulation of AUG-3387 that will be used to complete in vivo preclinical efficacy studies in the coming weeks and will proceed with toxicology studies by the end of 2021. Ongoing formulation development studies are expected to demonstrate that a sufficient dose of AUG-3387 to achieve a neutralizing concentration in the lungs can be delivered via already approved commercial dry powder inhaler devices.

In prior in vitro preclinical testing, AUG-3387 effectively neutralized SARS-CoV-2 and demonstrated activity against other major COVID variants of concern, including the previously identified Alpha variant (B.1.1.7), Beta variant (B.1.351), Gamma variant (P.1) and Kappa variant (B.1.617.1). The additional positive neutralization data against the delta variant reflects TFF and Augmenta’s ongoing commitment to monitor activity of AUG-3387 against emerging SARS-CoV-2 variants, and to develop a therapy that is as effective as possible against currently dominant strains.

TFF Pharmaceuticals and Augmenta also announced that Catalent Biologics has been selected to conduct cell line development utilizing their proprietary GPEx® platform and to lead drug substance manufacturing and scale-up efforts for AUG-3387 as the program advances through clinical development. Commenting on the agreement, Dr. Emig continued, “With AUG-3387 quickly emerging as a promising treatment against COVID-19, including for currently dominant variants, the selection of the CDMO is a critical decision along our development pathway. As one of the leading global providers of advanced biologics, Catalent brings exceptionally strong expertise in manufacturing of monoclonal antibodies. Augmenta and TFF look forward to working with them as the AUG-3387 program continues to advance.”

About the Development Agreement Between Augmenta Bioworks and TFF Pharmaceuticals

In November 2020, Augmenta Bioworks and TFF Pharmaceuticals announced establishment of a worldwide Joint Development and Collaboration Agreement to develop novel commercial products incorporating Augmenta’s human-derived monoclonal antibodies (mAbs) for potential COVID-19 therapeutics. TFF Pharmaceuticals also obtained the option to develop two additional Augmenta mAbs for indications other than COVID-19. These antibodies are expected to be developed utilizing TFF Pharmaceuticals’ Thin Film Freezing technology to manufacture dry powder formulations for inhalation delivery directly to the lungs of patients. The Agreement also includes the development of formulations suitable for parenteral administration, where the Thin Film Freezing dry powder formulations can be reconstituted, potentially mitigating the impacts of cold-chain storage and handling.
