FDA Provides Clearance to IND Application for Type 1 Diabetes Therapy SAB-142 by SAB Biotherapeutics
SAB Biotherapeutics (Nasdaq: SABS) announced that the FDA has cleared its IND application for SAB-142, a type 1 diabetes therapy, to proceed to a Phase 1 clinical trial in the US.
SAB-142, a human anti-thymocyte immunoglobulin (hIgG), aims to delay the onset or progression of type 1 diabetes. The ongoing HUMAN trial will assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of SAB-142 in both healthy volunteers and participants with type 1 diabetes.
The HUMAN trial is a randomized, double-blind, placebo-controlled, single-ascending dose study, with doses ranging from 0.03mg/kg to 2.5mg/kg. The trial design mimics the MELD-ATG study, whose topline results are expected in 2025.
The third cohort has been fully enrolled and dosed without observed serum sickness. This clearance marks a significant advancement in SAB's mission to slow disease progression in type 1 diabetes patients.

Insights
The FDA's clearance for SAB-142's IND application is a noteworthy development for SAB Biotherapeutics. This regulatory milestone enables the company to advance its therapy into Phase 1 clinical trials in the U.S., focusing on safety, tolerability and preliminary efficacy in type 1 diabetes patients.
Type 1 diabetes is an autoimmune condition where the body's immune system attacks insulin-producing cells in the pancreas. By targeting this with a human anti-thymocyte immunoglobulin, SAB-142 aims to delay disease progression. This approach shows promise in modulating the immune system without triggering adverse reactions like serum sickness, a common issue with similar therapies.
For investors, the progression to human trials marks a critical juncture, which can validate the company's novel therapy platform and pave the way for larger studies. It is important to note that Phase 1 trials primarily focus on safety and efficacy outcomes will be more evident in later stages.
In summary, the FDA's clearance signifies a positive step forward for SAB Biotherapeutics in the competitive field of immunotherapies for autoimmune diseases, but it’s still early in the clinical pipeline.
The FDA clearance represents a significant milestone for SAB Biotherapeutics and could positively impact the company's stock. This regulatory approval often serves as a validation of the underlying science and can boost investor confidence. The commencement of the Phase 1 trial also opens up potential for further funding and partnerships, which are important for clinical-stage biopharmaceutical companies.
Investors should also be aware of the risks. Early-phase trials are inherently risky and success is not guaranteed. Additionally, while the market for T1D therapies is substantial, competition is fierce, with several other companies pursuing similar immunotherapy solutions.
From a financial perspective, advancing to clinical trials can increase operational costs, so it's essential to monitor the company's cash flow and funding strategies. Positive trial outcomes could lead to significant upside, while failures could have a detrimental impact on stock price.
The market for type 1 diabetes therapies is robust and growing, driven by increasing incidence rates and advancements in treatment options. SAB-142's entry into clinical trials adds a new player into this competitive landscape. Should the therapy prove successful, it could capture a significant share of the market, particularly due to its unique approach of using human anti-thymocyte immunoglobulin to modulate the immune response.
However, the market is already occupied by established therapies and new entrants, so SAB Biotherapeutics will need to demonstrate clear clinical benefits and safety advantages over existing treatments.
Investors should consider the potential market size and SAB's ability to navigate regulatory pathways and secure market access. Long-term success will depend on clinical outcomes, regulatory approvals and effective commercialization strategies.
This regulatory clearance enables clinical development of SAB-142 in patients with type 1 diabetes in the US
MIAMI, May 21, 2024 (GLOBE NEWSWIRE) -- SAB Biotherapeutics (Nasdaq: SABS) (the “Company” or “SAB”), today announced that the U.S. Food and Drug Administration (FDA) has provided clearance for the Company’s investigational new drug (IND) application to proceed for its phase 1 clinical trial for type 1 diabetes (T1D) therapy SAB-142. SAB is a clinical-stage biopharmaceutical company with a novel immunotherapy platform developing a human anti-thymocyte immunoglobulin (hIgG) for delaying the onset or progression of T1D.
The IND allows for enrollment of patients with type 1 diabetes in the United States into the ongoing HUMAN trial designed to generate data enabling an upcoming Phase 2B trial. The HUMAN trial – fully HUman anti-thymocyte biologic in first-in-MAN clinical study – is a phase 1 randomized, double-blind, placebo-controlled, single-ascending dose, adaptive design clinical study designed to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of intravenous SAB-142 in healthy volunteers and participants with T1D.
“We are thrilled by FDA’s clearance of our IND for SAB-142, which marks a significant step forward in our mission to slow disease progression in patients with new or recent onset stage 3 type 1 diabetes,” states Samuel J. Reich, Chairman and CEO of SAB. “We look forward to expanding our clinical program with SAB-142 as we work to change the lives of people impacted by type 1 diabetes through our unique disease-modifying therapy.”
Trial Design
Phase 1 of SAB-142 is a first-in-man study to establish safety, tolerability, pharmacokinetic (PK), immunogenicity, and pharmacodynamic (PD) profile of a human anti-thymocyte biologic SAB-142. The study is designed as a randomized, double-blind, single-ascending dose trial, with a dose range of .03mg/kg up to 2.5mg/kg which is a similar dose range studied in the MELD-ATG study, a dose-ranging rabbit ATG study in patients with new onset T1D that will announce its topline result in 2025. Anticipated outcomes include validation of differentiated safety, immunogenicity, and tolerability profile of SAB-142 based on anticipated
About SAB-142
SAB-142 is a human alternative to rabbit anti-thymocyte globulin (ATG). SAB-142’s mechanism of action is analogous to that of rabbit ATG, which has been clinically validated in multiple clinical trials T1D, demonstrating the ability to slow down disease progression in patients with new or recent onset of Stage 3 type 1 diabetes.
Two clinical trials have shown that a single, low dose of rabbit ATG has demonstrated the ability to modulate the body’s immune response to help slow beta cell destruction and preserve the ability of these cells to generate insulin, which the body needs to regulate blood sugar and carry out all human activities.
SAB-142, like rabbit ATG, directly targets multiple immune cells involved in destroying pancreatic beta cells. By stopping immune cells from attacking beta cells, this treatment has potential to preserve insulin-producing beta cells. However, most humans treated with rabbit ATG develop serum sickness and anti-drug antibodies from exposure to the rabbit-derived antibody. SAB-142 is a human biologic treatment, intended to allow safe, consistent re-dosing for type 1 diabetes, a lifelong chronic disease, without the potential risk of inducing the major adverse immune reactions that can occur with administration of an animal ATG.
