Forte Biosciences, Inc. Announces Second Quarter 2024 Results and Provides Business Update

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

Second Quarter 2024 Business Highlights

“Forte continues to make excellent progress with FB102, our anti-CD122 monoclonal antibody therapeutic candidate. The SAD/MAD phase 1 healthy volunteer study has successfully completed and FB102 has demonstrated a good safety profile,” said Paul Wagner, Ph.D., Chairman and Chief Executive Officer of Forte Biosciences. “Based on the successful completion of the phase 1 healthy volunteer cohorts, Forte is initiating a patient study in celiac disease with data expected by the second quarter of 2025. 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 Updates

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 was comparable to vehicle. These observations suggest that FB102 is demonstrating selectivity with respect to inhibiting the intermediate vs high affinity IL2 receptor.

The phase 1 healthy volunteer SAD/MAD cohorts have successfully completed. The FB102 phase 1 healthy volunteer study demonstrated a good safety profile. Of note, in this study FB102 reported a significant reduction in the NK cell pharmacodynamic marker of the FB102 mechanism. Based on these results, Forte is advancing clinical development of FB102 into a celiac disease patient study with first patient dosing expected in the third quarter of 2024. Top-line results of the study are expected by the second quarter of 2025.

Second Quarter 2024 Operating Results

Research and development expenses were $5.7 million for the three months ended June 30, 2024, compared to $7.1 million for the same period in 2023. The decrease was primarily due to a decrease of approximately $1.5 million in manufacturing costs partially offset by an increase of approximately $0.1 million in payroll and related expenses due to an increase in Forte’s average headcount.

Research and development expenses were $10.1 million for the six months ended June 30, 2024, compared to $11.9 million for the same period in 2023. The decrease was primarily due to a decrease of approximately $4.1 million in manufacturing costs partially offset by an increase of approximately $1.3 million in clinical expenses as Forte advanced its FB102 program through clinical trials, and a net increase of approximately $1.0 million in payroll and related expenses due to an increase in Forte’s average headcount and related payments.

General and administrative expenses were $7.1 million for the three months ended June 30, 2024 compared to $1.9 million for the same period in 2023. The increase was primarily due to increases in legal and professional expenses.

General and administrative expenses were $10.5 million for the six months ended June 30, 2024, compared to $4.0 million for the same period in 2023. The increase was primarily due to increases in legal and professional expenses.

Net losses per share were $(0.27) and $(0.42) for the three months ended June 30, 2024 and 2023, and $(0.43) and $(0.74) for the six months ended June 30, 2024 and 2023, respectively.
