Announcement
Forte Biosciences, Inc announced positive results from the FB102 double-blind placebo-controlled phase 1b study in vitiligo
AI Summary
Forte Biosciences said its FB102 treatment showed positive results in a double-blind, placebo-controlled phase 1b study in vitiligo. The study enrolled 43 people, with 32 receiving FB102 and 11 receiving placebo. The main goal was to measure improvement in skin color loss using central review. FB102 showed a statistically significant benefit by day 64 and patients kept improving after the 12-week treatment period ended.
By week 24, FB102-treated subjects had an additional 8-point improvement after treatment stopped, and those with more severe disease at baseline improved by 14 more points. In total, 84% of FB102-treated subjects improved, while none got worse. By comparison, 27% of placebo patients got worse. Side effects were mild to moderate, and the company said FB102 continued to show a strong safety profile. Forte said it will discuss the results on a conference call.

- Indication:
- In celiac disease
Announcement
Forte Biosciences, Inc announced additional details from the oral presentation "FB102 prevents histological damage and mitigates gluten challenge-induced symptoms in a celiac disease phase 1b study - Jason Tye-Din, Walter and Eliza Hall Institute; Royal Melbourne Hospital" at the Tampere Celiac Disease Symposium 2025 (Tampere, Finland) on Friday September 12, 2025, further supporting the significant differentiation of FB102 in celiac disease.
AI Summary
Forte Biosciences presented new data on FB102 at the Tampere Celiac Disease Symposium 2025, showing significant protection against gluten-induced damage in a phase 1b trial. Patients receiving FB102 had a 1.5-unit drop in TCR γδ cell density versus a 3.9-unit increase with placebo (p=0.0007). These cells are known to drive inflammation and kill intestinal lining cells. FB102 also limited inflammation markers: Ki67-positive cells rose by 2.5 units compared to 8.6 units on placebo (p=0.0006).
In addition, natural killer (NK) cells dropped by 95% after FB102 dosing, indicating strong inhibition of the IL-15 pathway, which fuels celiac disease inflammation. Regulatory T cells remained similar between groups, suggesting that FB102 selectively targets harmful immune responses without affecting key immune regulators.
These results highlight FB102’s unique approach to preventing tissue damage and symptoms in celiac disease. A phase 2 trial is already underway with topline data expected in 2026.

AI Summary
Forte Biosciences shared new data from the oral presentation “FB102 prevents histological damage and mitigates gluten challenge-induced symptoms in a celiac disease phase 1b study” by Jason Tye-Din at the Tampere Celiac Disease Symposium on September 12, 2025. These findings further highlight FB102’s unique and targeted activity in celiac disease.
In the trial, FB102 reduced TCR γδ cell density by 1.5 from baseline versus a 3.9 increase with placebo (p=0.0007). Ki67-positive intraepithelial T cells rose by only 2.5 on FB102 compared to 8.6 with placebo (p=0.0006), indicating less inflammation. Natural killer cells dropped 95% after FB102 dosing, reflecting IL-15 pathway inhibition. There was no significant change in regulatory T cells at any timepoint.
These results underscore FB102’s differentiated profile in preserving intestinal health under gluten challenge. A phase 2 celiac trial is underway with topline data expected in 2026. Forte also anticipates data next year in vitiligo and alopecia areata studies.

- Announced Date:
- June 23, 2025
- Indication:
- In celiac disease
Announcement
Forte Biosciences, Inc. announced positive data from a Phase 1b trial in celiac disease for lead program FB102 (FB102-101).
AI Summary
Forte Biosciences, Inc. announced promising positive data from its Phase 1b trial in celiac disease for its lead program FB102 (FB102-101). In the study, 32 subjects were enrolled in a 3:1 randomization, receiving FB102 or placebo, followed by a 16-day gluten challenge. Key results showed that subjects on FB102 achieved better histological outcomes with a significant improvement in the composite VCIEL score compared to placebo. Additionally, the FB102 group showed a decrease in the density of CD3-positive T cells and a notable improvement in the villus:crypt ratio. Patients treated with FB102 also experienced a 42% reduction in gluten-induced gastrointestinal symptoms. These encouraging results support further research, as the company plans to advance into a Phase 2 celiac disease trial, with a topline readout expected in 2026.
