Forte Biosciences, Inc. (www.fortebiorx.com) (NASDAQ:FBRX), a clinical-stage biopharmaceutical company focused on autoimmune and autoimmune-related diseases, today announced positive data from a Phase 1b trial in celiac disease for lead program FB102 (FB102-101).

The company will be hosting a conference call today at 8:30 am ET. Prof. Jason Tye-Din, Head of Celiac Research at the Walter and Eliza Hall Institute and principal investigator in the FB102-101 study will be participating in the call.

The FB102-101 Phase 1b celiac disease study enrolled 32 subjects 3:1 randomized (24 on FB102 and 8 on placebo). Subjects received 4 doses of FB102 (10 mg/kg) and underwent a 16 day gluten challenge. In addition to safety and tolerability, the study assessed morphologic and inflammatory endpoints along with gluten challenge (GC) induced symptoms.

FB102 demonstrated a statistically significant benefit on the composite histological VCIEL endpoint (change from baseline). The mean VCIEL change from baseline was -1.849 for placebo subjects compared to 0.079 for FB102 treated subjects (p=0.0099).

The change in the density of CD3-positive T cells, or IELs, from baseline was an increase of 13.3 for placebo subjects compared to a decline of 1.5 for FB102 treated subjects (p=0.0035). Baseline IEL density was 25.6 for the placebo subjects and 23.5 for the FB102 treated subjects.

The mean change in the Vh:Cd ratio from baseline was -0.173 (0.21) for placebo subjects compared to -0.046 (0.09), a 73% improvement for FB102 treated subjects compared to placebo.

Gluten challenge induced GI symptoms (nausea, vomiting, diarrhea, abdominal pain and abdominal bloating) reported during the 16 day gluten challenge from patient diaries/AE collection demonstrated a 42% benefit for FB102 treated subject (4.0 events per subject) compared to placebo (6.9 events per subject).

There were no dropouts in the study. Treatment emergent adverse events (TEAE) were primarily mild (grade 1) with no grade 3 or higher SAEs reported in the FB102 arm.

"We want to congratulate all of the investigators and researchers that supported this study. I also want to acknowledge the incredible dedication and hard work of the Forte team. Celiac disease is debilitating for many patients with even trace exposure to gluten. FB102 has taken a big step forward towards addressing this very large unmet need with the results from this study. The Phase 2 celiac disease study is initiating with a topline readout expected in 2026." said Paul Wagner, Ph.D. CEO and Chairperson of Forte Biosciences. "These results are also very encouraging given the biology of the additional FB102 indications including vitiligo, alopecia areata and type 1 diabetes. We also look forward to reading out the topline results of the FB102 vitiligo study in the first half of 2026."
