Pipeline Updates and Anticipated Milestones

SAB continues to execute on its strategy for the development of proprietary immunotherapeutic fully-human antibodies, or fully-human immunoglobulins (hIgGs), to treat and prevent immune and autoimmune disorders with a strategic focus on T1D disease modification.

Clinical/Regulatory Update:

• Received approval by the Human Research Ethics Committee (HREC) to commence a First-in-Human Phase 1 clinical trial investigating SAB-142 in Australia. The Phase 1 trial will evaluate the company’s lead therapeutic candidate, SAB-142, a first in-class hIgG being developed as a disease-modifying treatment to delay the onset and progression of T1D. The trial is designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of SAB-142. Approval by the HREC is confirmation that SAB has successfully completed all pre-clinical safety and efficacy testing required to commence a Phase 1 clinical trial.
• Received Acknowledgement of a Clinical Trial Notification (CTN) from the Australian Government Department of Health Therapeutic Goods Administration (TGA) submitted for the Phase 1 study.
• Successfully registered the Phase 1 trial with the Australian New Zealand Clinical Trials Registry (ANZCTR). More information about the Phase 1 clinical trial with SAB-142 (ACTRN:12623001089628) can be found here.
• Phase 1 First-in-Human trial expected to commence Q42023 in Australia.
• US IND filing anticipated in 2024.
  

Strategy Update:

• Announced the Company has entered into a private placement offering that will provide up to $110 million in gross proceeds to SAB, which will used to clinically advance SAB-142, and is expected to advance to clinical trials in Q4 2023. SAB-142 is a fully-human alternative to rabbit anti-thymocyte globulin (rATG). SAB-142’s mechanism of action is similar to that of rATG, which has been clinically validated in multiple clinical trials for T1D, demonstrating the ability to slow down disease progression in patients with new or recent onset of Stage 3 T1D.
  
  The full proceeds, when funded, are expected to fund the company through 2026 and through topline Phase 2 results. Participating investors include Sessa Capital, BVF Partners, RTW Investments, Marshall Wace, ATW and the JDRF T1D Fund. The Offering will include several tranches as outlined in the Company’s filings with the SEC (including a current report on Form 8-K being filed on October 2, 2023).
  
  Two tranches have been completed to date:
  
  
  • • Issuance of Series A-1 Preferred Stock, the first tranche of the $110 million in private financing, totaling approximately $7.5 million of gross proceeds was closed on October 5, 2023.
      
    • Issuance of Series A-1 Preferred Stock or Series A-3 Preferred Stock, the second tranche of the $110 million in private financing, totaling approximately $59.6 million of gross proceeds was completed on November 10, 2023.

Q3 2023 Financial Results

Financial Guidance: Based on its current operating plans, SAB reaffirms that it expects its existing business plan, cash and cash equivalents, and anticipated cash flows will be sufficient to fund its operating expenses and capital expenditure requirements through the third quarter of fiscal year 2025.

• Research and Development (R&D) Expenses: R&D expenses were $4.0 million for three months ended September 30, 2023, compared to $7.4 million for the three months ended September 30, 2022. R&D expenses were $12.2 million for the nine months ended September 30, 2023, compared to $29.3 million for the nine months ended September 30, 2022. The decrease was primarily due to targeted cost reduction measures pausing certain unfunded research activities for our COVID-19 therapeutic and prioritizing our focus in the autoimmunity space with SAB-142, a disease-modifying fully human hIgG aimed at preventing onset or disease progression of Type 1 Diabetes.
• General and Administrative (G&A) Expenses: G&A expenses were $2.6 million for the three months ended September 30, 2023, compared to $4.0 million for the three months ended September 30, 2022. G&A expenses were $8.9 million for the nine months ended September 30, 2023, compared to $13.5 million for the nine months ended September 30, 2022. The decrease was primarily due to discretionary cost reduction measures and increased efficiencies as we continue to mature as a publicly traded company.
  
• Net Loss: Net loss was $5.1 million for the three months ended September 30, 2023, for an earnings per basic and diluted share of $(0.10), as compared to a net loss of $7.1 million for the three months ended September 30, 2022, for an earnings per basic and diluted share of $(0.16).
