Apogee Reports Second Quarter 2026 Financial Results and Recent Corporate and Pipeline Updates

AbbVie to acquire Apogee for $135.11 per share in cash for total equity value of approximately $10.9 billion, positioning differentiated immunology portfolio to reach more patients worldwide

Positive 16-week Phase 2 APEX Part B induction dose optimization results support planned advancement of zumilokibart into Phase 3 development in moderate-to-severe atopic dermatitis this year

SAN FRANCISCO and BOSTON, Aug. 10, 2026 (GLOBE NEWSWIRE) — Apogee Therapeutics, Inc. (Nasdaq: APGE), a clinical-stage biotechnology company advancing optimized, novel biologics with the potential for best-in-class profiles in the largest inflammatory and immunology (I&I) markets, today reported second quarter 2026 financial results, recent corporate updates and pipeline progress.

“The second quarter marked a transformational period for Apogee,” said Michael Henderson, M.D., Chief Executive Officer of Apogee Therapeutics. “The strength of our Phase 2 APEX Part B results further demonstrated the potential of zumilokibart to redefine treatment for patients with moderate-to-severe atopic dermatitis while reinforcing its broader pipeline-in-a-product opportunity across inflammatory diseases. These results, followed by our strategic financing collaboration with Blackstone Life Sciences and the now pending acquisition by AbbVie, reflect the progress our team has made in advancing a differentiated immunology portfolio. We are grateful to the patients, investigators and employees who made these milestones possible, and we believe AbbVie’s scientific expertise, global scale and commercial capabilities provide the best opportunity to realize the full potential of these programs for patients around the world.”

Corporate Updates

• Pending acquisition by AbbVie positions portfolio for global development and commercialization:
  • In June 2026, Apogee announced that it entered into a definitive agreement to be acquired by AbbVie. Under the terms of the agreement, AbbVie will acquire all outstanding shares of Apogee for $135.11 per share in cash, representing a total equity value of approximately $10.9 billion. The proposed acquisition is expected to strengthen AbbVie’s immunology portfolio while advancing the development of Apogee’s differentiated pipeline of therapies for inflammatory and immunological diseases. The transaction is expected to close in the third quarter of 2026, subject to customary closing conditions, including shareholder approval and receipt of required regulatory approvals.
     
• Strategic financing collaboration with Blackstone Life Sciences:
  • In May 2026, Apogee announced a strategic financing collaboration with Blackstone Life Sciences for up to $1.3 billion in flexible, non-dilutive capital to support the Phase 3 development and potential commercialization of zumilokibart. Combined with the company’s existing cash balance at the time, the financing was expected to position Apogee to achieve a self-sustainable financial profile through commercialization without the need for future equity financing.

Pipeline Progress

• APEX Phase 2 Part B met all primary and secondary endpoints with high statistical significance; dose optimization results informed dosing plans for upcoming Phase 3 trials expected to launch this year:
  • In May 2026, the company announced positive 16-week induction dose optimization results from Part B of the APEX Phase 2 trial evaluating zumilokibart in patients with moderate-to-severe atopic dermatitis. The trial met its primary endpoint with 65.9% of patients treated with mid-dose zumilokibart achieving EASI-75 (41.9% placebo adjusted). Key secondary endpoints were also met, with IGA 0/1 in 46.0% of patients, EASI-90 in 47.4%, I-NRS ≥4 improvement in 50.5%, EASI-100 in 16.5%, with very low disease activity (vLDA) in 20.6%, each demonstrating statistically significant improvements versus placebo. Zumilokibart was well tolerated, with a safety profile generally consistent with other agents in the class.
  • Based on these results, as well as findings from APEX Part A, the company selected the mid-dose regimen for planned Phase 3 initiation this year. 
     
• Apogee announced trial plans for expansion indications in EoE and asthma:
  • The ELEVATE Phase 2a trial, an open-label, proof-of-concept study evaluating zumilokibart in patients with eosinophilic esophagitis (EoE), will initiate in 2H 2026. The study is expected to enroll approximately 30 to 50 patients and will assess dosing every three or six months. The primary endpoint is histologic response, including reductions in eosinophil counts, with additional evaluation of endoscopic findings and patient-reported outcomes.
  • The ASPIRE Phase 2b trial, a randomized, placebo-controlled study evaluating multiple dosing regimens of zumilokibart in patients with moderate-to-severe asthma with elevated Type 2 biomarkers and a history of exacerbations, will initiate in 1H 2027. The study is designed to be potentially registrational and is expected to enroll approximately 500 patients randomized across dosing intervals of every three, six, or twelve months, or placebo. The primary endpoint is annualized exacerbation rate at Week 52, with additional assessments of lung function and symptoms.
     
• Combination pipeline continues to advance across AD and respiratory conditions for APG279 and APG273 with potential for improved efficacy and dosing:
  • The Phase 1b head-to-head study evaluating APG279 (zumilokibart + APG990) versus DUPIXENT® in atopic dermatitis is ongoing, with interim data expected in 2H 2026.
  • APG273 (zumilokibart + APG333), a long-acting IL-13/TSLP combination, continues to represent a differentiated respiratory program supported by positive Phase 1 data for APG333, with additional plans to be announced in 2H 2026.

Second Quarter 2026 Financial Results

• Cash Position: Cash, cash equivalents, marketable securities and long-term marketable securities were $1.3 billion as of June 30, 2026, compared to $621.2 million as of June 30, 2025.
• R&D Expenses: Research and development (R&D) expenses were $67.3 million for the quarter ended June 30, 2026, compared to $55.7 million for the quarter ended June 30, 2025. R&D expenses increased primarily driven by the continued development of our zumilokibart program and higher personnel and equity-based compensation expenses associated with the growth in our research and development team.
• G&A Expenses: General and administrative (G&A) expenses were $24.3 million for the quarter ended June 30, 2026, compared to $17.5 million for the quarter ended June 30, 2025. G&A expenses increased primarily due to increases in personnel-related expenses and equity-based compensation, primarily driven by increased headcount and an increase in the fair value of equity awards granted. These increases are the result of the company’s expansion of operations to support the growth of its business.
• Net Loss: Net loss was $85.9 million for the quarter ended June 30, 2026, compared to a net loss of $66.1 million for the quarter ended June 30, 2025. Net loss increased primarily as a result of higher R&D and G&A expenses as described above.
