Sufficient cash and government funding anticipated to operate through third quarter 2023

SIOUX FALLS, S.D., March 29, 2022 (GLOBE NEWSWIRE) — SAB Biotherapeutics (Nasdaq: SABS), (SAB), a clinical-stage biopharmaceutical company with a novel immunotherapy platform that produces specifically targeted, high-potency, fully-human polyclonal antibodies without the need for human donors, today provided a business update and reported financial results for the full year ended December 31, 2021.

“2021 was a pivotal year for SAB Biotherapeutics, as we successfully closed our business combination and debuted on the NASDAQ exchange, while advancing SAB-185 and SAB-176, our novel polyclonal antibodies for COVID-19 and influenza. Our work on SAB-185 propelled our science forward with a real-world proof-of-concept. It contributed greatly to our scientific knowledge and gave us tremendous confidence in what SAB can achieve with our innovative technology to address a variety of acute and chronic unmet medical needs. It also demonstrated the potential of our rapid response platform to address future global public health threats. The historic impact of influenza and the evolving COVID-19 pandemic continues to impact at-risk patients, such as those with underlying conditions or those who are immunocompromised. The need for potent therapeutics remains clear,” said Eddie J. Sullivan, Ph.D., co-founder, President and Chief Executive Officer of SAB Biotherapeutics. “We are extremely proud of our team and SAB’s role in responding to the COVID-19 health crisis. SAB remains dedicated to rapidly developing therapies that can play a role in both this pandemic and in future threats to public health.”

Dr. Sullivan continued, “Moving forward into 2022, we remain focused on leveraging the breadth of the platform to monetize both our pipeline programs and those outside our core therapeutic focus, including respiratory disease, oncology and monoclonal discovery. We continue to execute on the Rapid Response Antibody Program through our contract with the US Department of Defense, initiated in 2019, which has expanded and advanced significantly due to the accelerated progress made during the COVID-19 pandemic response. We also remain on track to release initial proof-of-principle data in demonstrating the potential of multi-targeted human polyclonals in oncology. With multiple milestones rapidly approaching, including the first clinical data from our platform, and the anticipated readout of the full dataset from our Phase 2a study of SAB-176 in seasonal influenza, we believe we are well positioned to deliver on the promise of our strategy to continue building a robust pipeline spanning immune and autoimmune disorders, and bringing much needed therapeutics to patients.”

2021 and Pipeline Updates and 2022 Anticipated Milestones

  • Phase 2 Full Data Readout for SAB-185 Expected to be Available Mid-2022. SAB-185 is a polyclonal antibody therapeutic candidate for the treatment of COVID-19. SAB-185 could be a valuable clinical tool for immunocompromised patients, and potentially as a therapeutic against future SARS‑CoV‑2 variants. SAB intends to continue to study SAB-185 in COVID-19 and is evaluating clinical plans for further development in targeted patient groups, including the potential for prophylactic or therapeutic use in targeted high-risk populations, along with the potential development of an injectable formulation, in addition to other indications.
    • SAB-185 was being assessed as part of the Phase 3 NIH ACTIV-2 master protocol evaluating treatments for COVID-19 in patients with mild-moderate infections at higher risk for progression to hospitalization.
    • As announced on February 25, 2022, due to low Omicron-related COVID-19 hospitalization and death rates that made the study design statistically unworkable, it was discontinued, as were trials from other companies participating in ACTIV-2, sponsored and funded directly by NIH.
    • SAB’s strong clinical data demonstrated in trials to date has given us increased confidence in our progress in developing SAB-185, which has contributed greatly to the collective body of science in virology, infectious disease and polyclonal therapy development. The extensive pre-clinical and clinical programs completed have expanded our knowledge over the past two years of the potential for Tc bovine-derived fully-human polyclonal antibody development. This accelerated development path, driven by the pandemic need for novel therapeutics to address emerging viruses and their mutations, and the work we anticipate completing in the coming months, is expected to significantly benefit scientific discovery and future patients.
    • We previously achieved positive review from an independent Data Safety Monitoring Board (DSMB) on the predefined interim Phase 2 safety and efficacy goal for advancement to Phase 3. The positive DSMB review was later confirmed on subsequent review of the full data set.
    • In December, we reported data demonstrating that SAB-185 retains in-vitro neutralization against the Omicron SARS-CoV-2 variant. Throughout 2021, we announced data supporting the potent neutralization of the Omicron, Gamma, Delta, Lambda and other circulating variants of concern in nonclinical studies, in addition to preclinical data indications that SAB-185 is believed to be significantly more potent than human-derived convalescent immunoglobulin G (IgG).
  • Continued execution on Rapid Response Antibody Program. The Rapid Response Antibody Program was initiated in 2019 through a three-stage, multi-year contract with the US Department of Defense (DOD) that was accelerated and expanded significantly due to the COVID-19 pandemic and increased need for therapeutics. SAB continues to build out this program, with multiple targets and other strategic activities to support the warfighter, in addition to facilitating readiness for future emerging threats.
    • Since 2019, progress on the Rapid Response Antibody Program has resulted in strategic company infrastructure, including full platform vertical integration with antigen development and production, plasma production, expanded manufacturing and quality control capacities. It has also resulted in expansion of our capabilities across all areas of late-stage biologics development including regulatory, quality assurance and clinical.
  • Phase 2a challenge study full data readout for SAB-176 expected mid-2022. SAB-176 is a polyclonal antibody therapeutic candidate recently evaluated in a Phase 2a Challenge study for the treatment of seasonal influenza.
    • In December, we announced Phase 2a topline data achieving statistically significant reductions in viral load and clinical symptoms while also appearing safe and well-tolerated.
  • Planned advanced IND-enabling studies for SAB-142. SAB-142 is a fully-human antithymocyte globulin therapeutic candidate for Type 1 diabetes and organ transplantation (induction/rejection) currently in preclinical development. The initial pilot study was completed in the first quarter of 2022 with further studies planned pending availability of appropriate study models.
  • Initial Proof-of-Principle Data for Immuno-oncology Expected in the Second Quarter of 2022.

2021 Highlights and Strategy Update

  • Successfully closed business combination with Big Cypress Acquisition Corp. SAB transitioned to a public company: The business combination, which closed in October 2021, resulted in cash proceeds, net of transaction costs, to SAB of approximately $34.3 million.
  • Added to NASDAQ Biotechnology Index.
  • R&D strategy focused on validating DiversitAb Platform and developing novel therapies for autoimmune disease. SAB plans to continue antigen development capabilities for its “strain add” strategy to further accelerate its capability to rapidly respond to new targets and diseases variants.
  • Business development strategy leverages the full breadth and capabilities of platform. SAB continues to execute on a multi-pronged business strategy to monetize pipeline programs, as well as those outside our core therapeutic focus, including respiratory disease, oncology and monoclonal discovery with both potential partners and collaborations with the US government.
  • Positive data readouts:
    • Announced multiple sets of robust in-vitro data supporting potent neutralization of SAB-185 against multiple SARS-CoV-2 variants, including Delta and Omicron.
    • Continuing to evaluate future clinical plans for SAB-185, including potential targeted applications, such as treatment in high-risk patient groups and alternate routes of administration.
  • Management Updates:
    • Appointed Russell Beyer as Chief Financial Officer. Appointed in September 2021, Beyer has more than 25 years of experience overseeing financial functions at pharmaceutical and other Fortune 100 firms including AstraZeneca, Teva Pharmaceuticals and HBO.
