Augmenta Bioworks and TFF Pharmaceuticals Announce Positive In Vitro Data Demonstrating Binding and Neutralization of the SARS-CoV-2 Delta Variant by Lead Anti-COVID-19 Antibody, AUG-3387
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

Scale-up Manufacturing for AUG-3387 Proceeding Rapidly; Early Batches Show Promising Results
Recent data indicates that the Delta variant, which was recently declared a “Variant of Concern” by the
“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.”
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
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.
