| Item 7.01 | Regulation FD Disclosure. |
On January 6, 2026, Apogee Therapeutics, Inc. (the “Company”) issued a press release and made publicly available a data presentation announcing positive interim data from the Phase 1b clinical trial of zumilokibart (APG777), its potentially best-in-class anti-IL-13 antibody, in patients with mild-to-moderate asthma and highlighted upcoming 2026 milestones. The Company will host a conference call and webcast today, Tuesday, January 6, 2026, at 8:00 a.m., Eastern Time, to discuss the data results.
Copies of the press release and the data presentation are furnished as Exhibit 99.1 and Exhibit 99.2, respectively, to this Current Report on Form 8-K and are incorporated by reference herein. The exhibits furnished under Item 7.01 of this Current Report on Form 8-K shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the Exchange Act or the Securities Act of 1933, as amended, regardless of any general incorporation language in such filing.
| Item 8.01 | Other Events. |
On January 6, 2026, the Company announced positive interim data from the Phase 1b clinical trial of zumilokibart (APG777) in patients with mild-to-moderate asthma and highlighted upcoming 2026 milestones. The Company recently received approval for the International Non-proprietary Name (INN) of zumilokibart for APG777. Zumilokibart is a novel, half-life extended anti IL-13 antibody.
Zumilokibart (APG777) Phase 1b Positive Interim Results
The Phase 1b clinical trial is a double-blind, placebo-controlled trial evaluating the safety and tolerability of zumilokibart in patients with mild-to-moderate asthma. The trial is designed to also evaluate fractional exhaled nitric oxide (“FeNO”) suppression, a key biomarker of Type 2 inflammation.
The trial enrolled 31 adult patients who were randomized 3:1 to zumilokibart versus placebo and participants received a single dose of 720 mg of zumilokibart or placebo on day 1. 19 of the patients with mild-to-moderate asthma had a FeNO baseline ≥25 ppb, representative of asthma with Type 2 inflammation, and as a result met the pre-specified criteria for the analysis population.
In the trial, zumilokibart demonstrated:
| • | A favorable safety profile; zumilokibart was well-tolerated in all patients. |
| o | In the 19 patients analysis population, the only treatment-emergent adverse event (“TEAE”) observed in more than one patient was gastroesophageal reflux disease (“GERD”; 2 patients). There were no Grade 3 or higher TEAEs or serious adverse events and no conjunctivitis, injection site reactions, or anti-drug antibodies (ADAs) were observed. |
| o | In the full safety population (N=31) that were on treatment (N=23), TEAEs occurring in more than one patient on zumilokibart were upper respiratory tract infection (N=3), nasopharyngitis (N=2), GERD (N=2), and arthralgia (N=2); there were no Grade 3 or higher TEAEs or serious adverse events. |
| • | Robust and durable suppression of FeNO, a biomarker of Type 2 inflammation that has shown the strongest correlation with exacerbations in asthma, following a single dose in the analysis population. |
| o | Maximum absolute mean FeNO reduction of 45 ppb (60% decrease from baseline) after a single dose. |
| o | Durable FeNO suppression through 16 weeks for all patients in the analysis population. |
| o | Suppression of FeNO through 32 weeks for those patients in the analysis population with available follow up at the time of the data cut (N=3), supporting the potential for 3- or 6- month dosing. |
| • | Positive trends observed in forced expiratory volume in one second (“FEV1”) and across Type 2 biomarkers for all available data in the analysis population. FEV1 is a pharmacodynamic measure of lung function. Further data from the study will be shared at upcoming medical conferences. |
The Company also reported that it observed improvement in asthma and sinusitis, as measured by improvements in ACQ-5 and SNOT-22 in patients with comorbid asthma or sinusitis, in the APEX Phase 2 Part A trial of zumilokibart in moderate to severe atopic dermatitis ("AD").
Anticipated 2026 Key Milestones
The Company described additional expected data readouts and milestones for 2026:
| • | Zumilokibart (APG777) Phase 2 APEX Part A (52-week) maintenance data readout – expected Q1 2026 |
| • | Zumilokibart (APG777) Phase 2 APEX Part B (16-week) induction data readout – expected Q2 2026 |
| o | The trial completed enrollment ahead of schedule and exceeded its target with a total of 347 patients, driven by strong interest from physicians and patients. |
| • | Initiation of zumilokibart (APG777) Phase 3 trial in AD – expected 2H 2026 enabling potential launch in 2029 |
| • | Phase 1b head-to-head clinical trial of APG279 (APG777+APG990) vs. DUPIXENT for moderate-to-severe AD readout remains on track – expected 2H 2026 |
| o | Trial upsized from approximately 50 to 80 patients due to strong patient enrollment. |
The Company confirmed that it believes it has cash runway into the second half of 2028.
