- Biomarker Results: Positive trends observed in 7 of 8 biomarkers. Statistically significant decreases were noted in three profibrotic biomarkers:
- Galectin-7 (GAL-7): p=0.0014
- Thymic stromal lymphopoietin (TSLP): p=0.0223
- Collagen 1 alpha chain (Col-1α1): p=0.0489
- Safety: LTI-03 was generally well-tolerated with no serious adverse events reported. No inflammation was induced in peripheral blood mononuclear cells.
