Forte Biosciences, Inc. (www.fortebiorx.com) (NASDAQ: FBRX), a clinical-stage biopharmaceutical company focused on autoimmune and autoimmune-related diseases, today announced third quarter 2024 results and provided a business update.

Third Quarter 2024 Business Highlights

“We continue to make excellent progress with FB102 and have begun dosing patients in a celiac disease clinical trial. In addition to safety and tolerability, we will be assessing the histological impact as well as a variety of other activity parameters. The topline data is expected to readout in the second quarter of 2025,” said Paul Wagner, Ph.D., Chairman and Chief Executive Officer of Forte Biosciences. “Based on the biology of celiac disease and the mechanism of action of FB102, we are excited about the potential in celiac disease, an indication with a significant unmet need. We believe the data to date supports the significant potential for FB102 across a variety of autoimmune and autoimmune-related diseases with large addressable markets and we look forward to pursuing these opportunities as we continue to advance the FB102 program.”

R&D and Clinical Development Summary

In FB102 mechanistic in-vitro studies, human donor T and NK cells were stimulated with either IL2 or IL15 in the presence or absence of FB102. FB102 significantly inhibited proliferation and activation at levels comparable to unstimulated cells. Human donor regulatory T cell (Treg) studies stimulated with IL2 demonstrated comparable proliferation both in the presence and absence of FB102.

In the 4- and 13-week nonhuman primate (NHP) studies, after a single dose, FB102 demonstrated significant reductions in the NK cell pharmacodynamic marker. Additionally, after multiple doses at exposures comparable to human therapeutic doses, Treg levels in the FB102 dosing arm were comparable to vehicle. These observations suggest that FB102 is demonstrating selectivity with respect to inhibiting the intermediate versus high affinity IL2 receptor.

The phase 1 healthy volunteer SAD/MAD cohorts have completed successfully. The FB102 phase 1 healthy volunteer trial demonstrated a good safety profile. Of note, this trial reported a significant reduction in the NK cell pharmacodynamic marker of the FB102 mechanism. Based on these results, Forte has advanced clinical development of FB102 into a celiac disease patient trial. Top-line results of the study are expected in the second quarter of 2025.

Third Quarter 2024 Operating Results

Research and development expenses were $5.9 million for the three months ended September 30, 2024, compared to $6.4 million for the same period in 2023. The decrease was primarily due to a decrease of $3.0 million in manufacturing costs partially offset by an increase of $2.5 million in clinical and other expenses.

Research and development expenses were $16.0 million for the nine months ended September 30, 2024, compared to $18.3 million for the same period in 2023. The decrease was primarily due to a decrease of $7.5 million in manufacturing costs partially offset by an increase of $4.0 million in clinical and other expenses as we advanced our FB102 program through clinical trials, and a net increase of $1.2 million in payroll and related expenses due to an increase in our average headcount and related costs.

General and administrative expenses were $2.8 million for the three months ended September 30, 2024 compared to $3.8 million for the same period in 2023. The decrease was primarily due to decreases in legal and professional expenses.

General and administrative expenses were $13.3 million for the nine months ended September 30, 2024, compared to $7.8 million for the same period in 2023. The increase was primarily due to increases in legal and professional expenses.

Net losses per share were $(4.54) and $(6.57) for the three months ended September 30, 2024 and 2023, and $(15.35) and $(23.97) for the nine months ended September 30, 2024 and 2023, respectively.

Forte ended the third quarter 2024 with $16.4 million in cash and cash equivalents. In August 2024, Forte effected a 1:25 reverse split and has 1.46 million shares of common stock outstanding on a post-split basis as of September 30, 2024.
