First Tracks Biotherapeutics Announces Second Quarter 2026 Financial Results and Provides Business Update
•Completed enrollment for Cohort 1 (gluten challenge) of Phase 1b ANB033 trial in celiac disease (CeD); top-line Cohort 1 data reaffirmed for Q4 2026
•Cohort 2 (mucosal healing) enhanced to enroll up to 40 patients including those with a broad range of histologic (Vh:Cd ratio ≤ 2.5) and symptom severity to further inform future development; top-line Cohort 2 data anticipated in Q1 2027
•U.S. FDA granted Fast Track designation for ANB033 for the treatment of CeD
•Enrollment ongoing for Phase 1b ANB033 trial in eosinophilic esophagitis (EoE); top-line data anticipated in Q3 2027
•Reiterating cash-runway into Q2 2028, including the expansion of ANB033 into two additional indications in H1 2027
SAN DIEGO, CA — Aug. 12, 2026 — First Tracks Biotherapeutics, Inc. (Nasdaq: TRAX), a clinical-stage biotechnology company advancing antibody therapeutics that modulate immune pathways implicated in autoimmune and inflammatory diseases, today reported financial results for the second quarter ended June 30, 2026, and provided a business update.
“First Tracks continues to execute against a broad development strategy for our potentially best-in-class CD122 antagonist, ANB033, and anticipates treating patients across four indications in 2027. We believe ANB033 is uniquely positioned to deliver differentiated clinical and biological outcomes across multiple immune-mediated diseases,” said Daniel Faga, president and chief executive officer. “In celiac disease, FDA’s Fast Track designation for ANB033 underscores both the urgency of the significant unmet need for patients and the potential of this program. We will report top-line data from Cohort 1 of the Phase 1b trial in Q4 2026, evaluating ANB033's potential to prevent gluten-induced mucosal injury. Cohort 2 of this study is enrolling patients with disease across a wide range of histologic and symptom severity at baseline with the goal of generating deeper insights into timing to mucosal healing and disease biology. We anticipate reporting these data in Q1 2027, followed by top-line data from our Phase 1b trial of ANB033 in eosinophilic esophagitis in Q3 2027.”
ANB033 (CD122 antagonist)
•Phase 1b trial in celiac disease ongoing
oU.S. FDA granted Fast Track designation to ANB033 for the treatment of people with CeD on a gluten-free diet
o70-patient trial assessing one dose level of subcutaneously administered ANB033 vs. placebo (randomized 1:1) across two different cohorts
▪Cohort 1 (n=30) is a gluten-challenge study to assess the prevention of mucosal damage through six weeks
•Top-line Cohort 1 data reaffirmed for Q4 2026
▪Cohort 2 (n=40) assesses the possibility of mucosal healing through 12 weeks
•Cohort enhanced to enroll up to 40 patients including those with a broad range of histologic (Vh:Cd ratio ≤ 2.5) and symptom severity to further inform future development
•Enrollment ongoing with top-line Cohort 2 data anticipated in Q1 2027
•Phase 1b trial in EoE ongoing
o50-patient cohort assessing one dose level of subcutaneously administered ANB033 vs. placebo (randomized 1:1) through 12 weeks
oTop-line Phase 1b data anticipated in Q3 2027
•Plan to initiate Phase 2 trials in two additional indications in H1 2027
ANB101 (BDCA2 modulator)
•Phase 1a trial in healthy volunteers completed
oCurrently evaluating potential development approach informed by clinical and translational evidence, as well as competitor registrational data in systemic lupus erythematosus (SLE) and cutaneous lupus erythematosus (CLE) anticipated in Q4 2026 and early 2027, respectively
Rosnilimab (Pathogenic T cell depleter)
•Currently assessing ROE-maximizing strategic options to progress the potential development of rosnilimab in rheumatoid arthritis (RA) and other indications
Second Quarter 2026 Financial Results
•The separation of AnaptysBio and First Tracks Biotherapeutics was completed on April 20, 2026. As a result, from January 1, 2026 to April 19, 2026 and the three and six months ended June 30, 2025, the financial results include assets, liabilities and expenses related to both companies. The combined financial statements reflect allocations of certain expenses from the financial statements of Anaptys including research and development expenses and administrative expenses. These allocations include, but are not limited to, executive management, employee compensation and benefits, facilities and operations, information technology, business development, financial services (such as accounting, audit, and tax), legal, insurance and stock-based compensation.
•Cash, cash equivalents and investments totaled $168.0 million as of June 30, 2026.
•Research and development expenses were $25.6 million and $59.6 million for the three and six months ended June 30, 2026, compared to $39.3 million and $80.7 million for the three and six months ended June 30, 2025. The decrease for the three and six months ended June 30, 2026 was primarily due to decreased development costs for rosnilimab and ANB032 offset by increased costs relating to the Phase 1 trials for ANB033.
•General and administrative expenses were $9.3 million and $28.1 million for the three and six months ended June 30, 2026, compared to $6.6 million and $16.4 for the three and six months ended June 30, 2025. The increase was due primarily to the allocation of legal costs for the separation of the company.
•Net loss was $33.4 million and $83.9 million for the three and six months ended June 30, 2026, or a net loss per share of $0.95 and $2.40, compared to a net loss of $42.4 million and $89.6 million for the three and six months ended June 30, 2025, or a net loss per share of $1.47 and $3.02.
