SAN FRANCISCO and WALTHAM, Mass., May 12, 2025 (GLOBE NEWSWIRE) — Apogee Therapeutics, Inc., (Nasdaq: APGE), a clinical-stage biotechnology company advancing novel biologics with the potential for differentiated efficacy and dosing in the largest inflammatory and immunology (I&I) markets, including for the treatment of atopic dermatitis (AD), asthma, eosinophilic esophagitis (EoE), chronic obstructive pulmonary disease (COPD) and other I&I indications, today provided business updates, pipeline progress and reported first quarter 2025 financial results.
“2025 is poised to be a transformational year for Apogee, and we are pleased with the strong execution in the first quarter as we continue to advance therapies with the goal of reshaping the standard of care for patients living with I&I diseases,” said Michael Henderson, M.D., Chief Executive Officer of Apogee. “We have made significant progress in our Phase 2 APEX trial of APG777, which is actively enrolling Part B and on track for the interim 16-week readout from Part A mid-year. Momentum continues across our programs, driven by the initiation of our Phase 1b trial of APG777 in patients with mild-to-moderate asthma, today’s announcement of positive interim clinical trial results from our Phase 1b trial of APG808 in patients with mild-to-moderate asthma, as well as the positive Phase 1 interim readout for APG990, which exceeded all trial objectives and unlocked the potential for dosing APG279 (APG777 + APG990) two- to four- times per year with a single 2 mL co-formulated injection. Following these encouraging results from APG990, we are advancing our first-in-class combination strategy with plans to initiate a head-to-head Phase 1b study of APG279 versus DUPIXENT in AD later this year. With a very strong cash position and multiple catalysts across our portfolio in the months ahead, we are looking forward to an exciting and productive 2025 and 2026.”
New independent market research reinforces APG777’s potential to become a market leader in the rapidly expanding AD biologic space:
Apogee conducted third-party quantitative market research in April 2025 and asked US patients and physicians the likelihood that they would switch to APG777 from their current or previous biologic assuming APG777 had similar efficacy and overall results to DUPIXENT and an every 3-month, or quarterly, injection maintenance schedule.
- Responses demonstrated that APG777 was highly preferred over current biologic options by patients and physicians
- 96% of patients currently on a biologic, both controlled and inadequately controlled, would likely switch to APG777.
- 80% of physicians would likely start their biologic naive patients on APG777, while 83% of physicians would likely switch inadequately controlled biologic patients to APG777.
- 67% of physicians are open to switching their controlled patients to a quarterly dose of APG777.
- Compared to a hypothetical daily oral with equivalent efficacy and safety, patients and providers prefer APG777’s quarterly dosing profile:
- Patients prefer the APG777 profile by more than 3 to 1.
- Providers prefer the APG777 profile by nearly 4 to 1.
“Based on the recent market research we commissioned, APG777’s potential quarterly dosing is highly preferred by both physicians and patients to other available options. Physicians expressed strong interest in both initiating new-to-biologic patients to APG777 as well as switching patients already on biologics to APG777, assuming comparable efficacy and safety to current biologics,” said Jeff Hartness, Chief Commercial Officer of Apogee. “The AD biologic market is expanding rapidly—with year-to-date growth of 23% in total prescriptions and 44% in new-to-brand prescriptions—and new entrants are accelerating the shift from topicals to biologics. We believe APG777 is well positioned to transform the AD treatment landscape and significantly improve the quality of life for patients living with moderate-to-severe AD.”
Pipeline Highlights and Upcoming Milestones
- Apogee continues to execute APG777 monotherapy program in AD and expansion indications: APG777 is a novel, subcutaneous (SQ), extended half-life monoclonal antibody (mAb) targeting IL-13 – a critical cytokine in inflammation and a primary driver of AD.
- The Phase 2 APEX clinical trial of APG777 is progressing, with Part A fully enrolled and Part B actively enrolling patients with moderate-to-severe AD. The company expects to report 16-week topline data from Part A of the trial in mid-2025 and from Part B in the second half of 2026.
- Apogee today announced that the first patient has been dosed in a Phase 1b trial of APG777 in patients with mild-to-moderate asthma. The primary endpoint of the trial is safety and tolerability, with secondary endpoints exploring pharmacokinetics (PK), FeNO suppression of APG777, with readout expected in the first half of 2026.
- The company also plans to initiate a Phase 2 trial in EoE in 2026.
- APG279 (APG777 + APG990) Phase 1b head-to-head study against DUPIXENT on track to initiate in 2025: APG990 is a novel, SQ, extended half-life mAb targeting OX40L, and the combination with APG777 offers the potential for improved clinical responses over monotherapy across a variety of I&I diseases while Apogee’s approach of co-formulating two extended half-life mAbs provides the potential for first-in-class and best-in-class dosing.
- In March 2025, Apogee reported positive APG990 Phase 1 interim results in healthy volunteers, unlocking potential maintenance dosing every three and six months for APG279 (APG777 + APG990)
- Apogee plans to initiate its first-in-class combination trial, a Phase 1b trial designed to evaluate the safety, PK, pharmacodynamics and efficacy of APG279 against DUPIXENT in patients with moderate-to-severe AD this year, with an interim readout expected in the second half of 2026.
- Progress continues in our combination approach of APG777 + APG333: APG333 is a novel, SQ, extended half-life mAb targeting thymic stromal lymphopoietin (TSLP), a key driver of Type 2 and Type 3 inflammation in eosinophilic and non-eosinophilic conditions.
- A Phase 1 trial of APG333 in healthy volunteers is underway, with data expected in the second half of 2025.
- Positive interim data for APG808 Phase 1b trial in asthma reported: APG808 is a novel, SQ extended half-life mAb targeting IL-4Rα, a target with clinical validation across eight Type 2 allergic diseases. In preclinical studies, APG808 has similar binding and femtomolar affinity for IL-4Rα as compared to DUPIXENT and has demonstrated similar inhibition to DUPIXENT.
- Today, the company reported positive interim results of the Phase 1b trial of APG808 in patients with mild-to-moderate asthma. The results demonstrated that APG808 was well-tolerated, with multiple doses of APG808 resulting in rapid suppression of FeNO, a biomarker of Type 2 inflammation that is associated with exacerbations in asthma, with a maximal robust FeNO decrease from baseline of 53% and sustained FeNO decrease from baseline of 50% at 12 weeks.
- APG808’s optimized PK profile coupled with FeNO suppression out to 12-weeks reinforce the potential for 2-months or longer maintenance dosing, offering a significant advantage compared to the current bi-weekly standard of care.
First Quarter 2025 Financial Results
- Cash Position: Cash, cash equivalents and marketable securities were $681.4 million as of March 31, 2025, compared to $731.1 million as of December 31, 2024. Based on current operating plans, Apogee expects its existing cash, cash equivalents and marketable securities will enable the company to fund its operating expenses into the first quarter of 2028.
- R&D Expenses: Research and development (R&D) expenses were $46.4 million for the quarter ended March 31, 2025, compared to $28.7 million for the quarter ended March 31, 2024. R&D expenses increased primarily due to the advancement of the pipeline and continued development of the company’s programs, and increases in personnel-related expenses and equity-based compensation, associated with the growth in the company’s R&D team.
- G&A Expenses: General and administrative (G&A) expenses were $16.7 million for the quarter ended March 31, 2025, compared to $9.5 million for the quarter ended March 31, 2024. 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 in its business.
- Net Loss: Net loss was $55.3 million for the quarter ended March 31, 2025, compared to a net loss of $32.1 million for the quarter ended March 31, 2024. Net loss increased primarily as a result of higher R&D and G&A expenses as described above, partially offset by higher interest income.
