SAB Biotherapeutics announced positive Phase 1 clinical data for its SAB-142 candidate in adult patients with established Type 1 Diabetes (T1D). The data demonstrated early signals of C-peptide preservation at Day 120, suggesting the drug may help maintain beta cell function.
Red Flags
- Extremely small sample size (n=4 for the treatment group) limits the statistical significance of the findings.
- One of the two placebo participants discontinued the study early for personal reasons, leaving only one placebo comparator for the Day 120 endpoint.
- The data is short-term (120 days), whereas T1D disease modification typically requires longer-term observation.
Key Facts
- The Phase 1 HUMAN clinical trial evaluated SAB-142 in a cohort of 6 adult participants (4 treated, 2 placebo).
- SAB-142 treated participants (n=4) showed no decrease in C-peptide levels at Day 120 compared to baseline.
- The single placebo participant who completed the study through Day 120 showed a decrease in C-peptide levels.
- Treated participants received a dose of 2.5 mg/kg of SAB-142.
- The study participants were aged 19 to 40 years with Stage 3 T1D diagnosis within 28-40 months of randomization.
