Rhea-AI Filing Summary

Apogee Therapeutics (APGE) filed an 8-K to disclose positive 16-week data from Part A of its Phase 2 APEX trial evaluating APG777, an anti-IL-13 antibody, in moderate-to-severe atopic dermatitis (AD). The randomized, placebo-controlled study (n = 123; 2:1 randomization) met its primary endpoint, delivering a 71.0% mean EASI score reduction versus 33.8% for placebo. Key secondary endpoints also favored APG777, with EASI-75 achieved by 66.9% of treated patients (24.6% placebo) and EASI-90 by 33.9% (14.7% placebo). Exposure-response analyses showed up to 89.5% EASI-75 in the highest drug-exposure quartile.

Safety appeared benign: TEAEs occurred in 56.1% of treated subjects versus 63.4% placebo, serious TEAEs were 1.2% vs 2.4%, and no injection-site reactions were reported. Common events—non-infective conjunctivitis, URTI, nasopharyngitis—were comparable or lower than placebo.

Next steps: Part B (�280 pts, four-arm dose optimisation) is enrolling with 16-week data expected mid-2026, enabling a planned Phase 3 start in 2026. Maintenance data (3-/6-month dosing) from Part A are due 1H 2026. A separate Phase 1b head-to-head trial of APG279 versus Dupixent has begun, with readout 2H 2026.

The company will host a conference call on 7 July 2025 at 8:00 a.m. ET to review results. Exhibits 99.1 and 99.2 contain the full press release and deck; they are furnished, not filed.

Apogee Therapeutics (APGE) ha presentato un modulo 8-K per comunicare dati positivi a 16 settimane della Parte A della sua sperimentazione di Fase 2 APEX, che valuta APG777, un anticorpo anti-IL-13, nella dermatite atopica da moderata a grave (AD). Lo studio randomizzato e controllato con placebo (n = 123; randomizzazione 2:1) ha raggiunto il criterio di efficacia primario, con una riduzione media del punteggio EASI del 71,0% rispetto al 33,8% del placebo. Anche gli endpoint secondari chiave hanno favorito APG777, con il 66,9% dei pazienti trattati che ha raggiunto EASI-75 (24,6% placebo) e il 33,9% che ha raggiunto EASI-90 (14,7% placebo). Le analisi di esposizione-risposta hanno mostrato fino all'89,5% di EASI-75 nel quartile con la più alta esposizione al farmaco.

La sicurezza è risultata favorevole: gli eventi avversi correlati al trattamento (TEAE) si sono verificati nel 56,1% dei soggetti trattati contro il 63,4% del placebo, gli eventi avversi gravi sono stati l'1,2% contro il 2,4%, e non sono state riportate reazioni nel sito di iniezione. Gli eventi comuni � congiuntivite non infettiva, infezioni delle vie respiratorie superiori, nasofaringite � erano comparabili o inferiori rispetto al placebo.

Prossimi passi: La Parte B (circa 280 pazienti, ottimizzazione della dose su quattro bracci) è in corso di arruolamento, con dati a 16 settimane previsti per metà 2026, permettendo l'avvio pianificato della Fase 3 nel 2026. I dati di mantenimento (dosaggio a 3/6 mesi) della Parte A sono attesi nella prima metà del 2026. È iniziato un trial separato di Fase 1b in confronto diretto tra APG279 e Dupixent, con risultati attesi nella seconda metà del 2026.

L'azienda terrà una conference call il 7 luglio 2025 alle 8:00 a.m. ET per esaminare i risultati. Gli allegati 99.1 e 99.2 contengono il comunicato stampa completo e la presentazione; sono forniti, non depositati.

Apogee Therapeutics (APGE) a déposé un formulaire 8-K pour divulguer des données positives à 16 semaines de la Partie A de son essai de Phase 2 APEX évaluant APG777, un anticorps anti-IL-13, dans la dermatite atopique modérée à sévère (AD). L'étude randomisée, contrôlée par placebo (n = 123; randomisation 2:1) a atteint son critère principal, avec une réduction moyenne du score EASI de 71,0 % contre 33,8 % pour le placebo. Les critères secondaires clés ont également favorisé APG777, avec 66,9 % des patients traités atteignant EASI-75 (24,6 % placebo) et 33,9 % atteignant EASI-90 (14,7 % placebo). Les analyses exposition-réponse ont montré jusqu'à 89,5 % d'EASI-75 dans le quartile d'exposition médicamenteuse le plus élevé.

La sécurité est apparue favorable : les événements indésirables liés au traitement (TEAEs) sont survenus chez 56,1 % des sujets traités contre 63,4 % pour le placebo, les TEAEs graves étaient de 1,2 % contre 2,4 %, et aucune réaction au site d'injection n'a été rapportée. Les événements courants � conjonctivite non infectieuse, infections des voies respiratoires supérieures, nasopharyngite � étaient comparables ou inférieurs au placebo.

Prochaines étapes : La Partie B (environ 280 patients, optimisation de dose en quatre bras) est en cours d'inclusion, avec des données à 16 semaines attendues à la mi-2026, permettant un démarrage prévu de la Phase 3 en 2026. Les données de maintenance (posologie à 3/6 mois) de la Partie A sont attendues au premier semestre 2026. Un essai distinct de Phase 1b en confrontation directe entre APG279 et Dupixent a débuté, avec des résultats attendus au second semestre 2026.

Apogee Therapeutics (APGE) hat eine 8-K Meldung eingereicht, um positive 16-Wochen-Daten aus Teil A der Phase-2-Studie APEX bekannt zu geben, in der APG777, ein Anti-IL-13-Antikörper, bei mittelschwerer bis schwerer atopischer Dermatitis (AD) untersucht wird. Die randomisierte, placebokontrollierte Studie (n = 123; 2:1 Randomisierung) erreichte den primären Endpunkt mit einer durchschnittlichen EASI-Punktminderung von 71,0 % gegenüber 33,8 % beim Placebo. Wichtige sekundäre Endpunkte sprachen ebenfalls für APG777, mit 66,9 % der behandelten Patienten, die EASI-75 erreichten (24,6 % Placebo) und 33,9 % EASI-90 (14,7 % Placebo). Die Expositions-Wirkungs-Analysen zeigten bis zu 89,5 % EASI-75 im Quartil mit der höchsten Medikamentenexposition.

Die Sicherheit zeigte sich günstig: TEAEs traten bei 56,1 % der behandelten Probanden im Vergleich zu 63,4 % im Placebo auf, schwere TEAEs betrugen 1,2 % gegenüber 2,4 % und es wurden keine Injektionsstellenreaktionen gemeldet. Häufige Ereignisse � nicht-infektiöse Konjunktivitis, obere Atemwegsinfektionen, Nasopharyngitis � waren vergleichbar oder niedriger als beim Placebo.

Nächste Schritte: Teil B (�280 Patienten, vierarmige Dosisoptimierung) wird derzeit rekrutiert, mit 16-Wochen-Daten, die Mitte 2026 erwartet werden, was den geplanten Start der Phase 3 im Jahr 2026 ermöglicht. Erhaltungsdaten (3-/6-Monats-Dosierung) aus Teil A werden für das erste Halbjahr 2026 erwartet. Eine separate Phase-1b-Kopf-an-Kopf-Studie von APG279 gegen Dupixent wurde begonnen, mit Ergebnissen im zweiten Halbjahr 2026.

Das Unternehmen wird am 7. Juli 2025 um 8:00 Uhr ET eine Telefonkonferenz abhalten, um die Ergebnisse zu besprechen. Die Anhänge 99.1 und 99.2 enthalten die vollständige Pressemitteilung und die Präsentation; sie werden bereitgestellt, nicht eingereicht.

Positive
  • Primary endpoint met: 71% mean EASI reduction vs 34% placebo (p<0.05).
  • High responder rates: 66.9% EASI-75 and 33.9% EASI-90 exceed published biologic data.
  • Favorable safety: Lower TEAEs than placebo; 0 injection-site reactions; serious TEAEs 1.2%.
  • Clear exposure-response supports dose optimisation in Part B, increasing likelihood of Phase 3 success.
  • Long-interval maintenance dosing (3�6 months) being evaluated, a potential commercial differentiator.
Negative
  • Early-stage data: Results are from 16-week interim of Part A; durability beyond Week 16 unproven.
  • Need for larger confirmation: Part B and Phase 3 trials must replicate efficacy and safety to secure approval.
  • Competitive landscape: Dupixent and other IL-13/IL-4 inhibitors are entrenched; head-to-head data pending.
  • Financing risk: Ongoing trials (Part B, Phase 1b, future Phase 3) will require significant capital, raising dilution concerns.

Insights

TL;DR: Strong efficacy and clean safety elevate APG777’s profile; Phase 3 readiness hinges on Part B confirmation.

The 71% EASI reduction and 67% EASI-75 surpass historical Dupixent benchmarks (~50-60%), suggesting potential best-in-class efficacy. Safety signals are benign, with fewer TEAEs than placebo and no injection-site reactions, easing regulatory risk. The clear exposure-response guides dose optimisation in Part B, increasing probability of success. If Part B replicates high-quartile exposure outcomes, APG777 could challenge Dupixent’s franchise when it enters Phase 3 in 2026. However, durability and paediatric data are still missing, and commercial timelines assume smooth execution. Overall impact: positive.

TL;DR: Read-through materially de-risks APG777, but value inflection still 12-18 months away.

The data move APGE up the derisking curve, justifying a lower discount rate for the AD program. Yet the catalyst path—Part B data (mid-26) and Phase 3 start (late-26)—means near-term cash burn persists with no revenue visibility. Investors must weigh dilution risk against improved probability-of-success. Competitive overhang from IL-13/IL-4 combo assets and biosimilars remains a headwind, though APG777’s 3-6-month maintenance dosing could offer a compliance edge.

Item 8.01 Other Events.

 

On July 7, 2025, the Company announced (1) positive 16-week data from Part A of the Phase 2 APEX clinical trial of APG777, its potentially best-in-class anti-IL-13 antibody, in patients with moderate-to-severe AD, and (2) that the first patient has been dosed in its Phase 1b head-to-head trial of APG279 (IL-13 + OX40L) in patients with moderate-to-severe AD, in comparison to DUPIXENT, with readout expected in the second half of 2026.

 

APEX Phase 2 Part A Key 16-Week Results

 

The Phase 2 APEX clinical trial is a randomized, placebo-controlled study evaluating APG777 in patients with moderate-to-severe AD. Part A of the trial enrolled 123 adult patients who were randomized 2:1 to APG777 versus placebo and received an induction regimen dosing of 720mg at Weeks 0 and 2, followed by 360mg at Weeks 4 and 12. Patients benefiting from treatment continued maintenance dosing, evaluating 3- or 6-month dosing of APG777. The primary endpoint of Part A is mean percentage change in Eczema Area Severity Index (“EASI”) score from baseline at Week 16. Secondary endpoints include EASI-75, EASI-90, Validated Investigator Global Assessment (“IGA”) 0/1 and Itch Numeric Rating Scale (“NRS”) at Week 16. 

 

Initial 16-week findings from APEX Part A include efficacy results, which compare favorably versus standard of care across endpoints as well as rapid onset of itch relief and lesion reduction, and a favorable safety profile consistent with its class:

 

·The trial met its primary endpoint, with APG777 showing significantly greater least squares mean percent change from baseline at Week 16 with an EASI reduction of 71.0% compared to placebo of 33.8% (p < 0.001).

 

·Highest absolute and placebo-adjusted EASI-75 of any biologic with 66.9% of participants treated with APG777 achieving EASI-75 compared to 24.6% on placebo (p < 0.001)
oPre-specified sensitivity analysis showed consistent results in both moderate and severe patients
oAdditionally, an exposure-response relationship was observed, with patients in the two highest quartiles of exposures achieving the highest EASI-75 response at Week 16, 83.3% for quartile three and 89.5% for quartile four
§APEX Part B is testing a higher dose of APG777, which is projected to achieve average exposures in line with the highest quartile of exposures from Part A

 

·Additional key secondaries were in line with standard of care, including vIGA 0/1 and EASI-90
ovIGA 0/1 of 34.9% compared to placebo of 17.3% (p < 0.05)
oEASI-90 of 33.9% compared to placebo of 14.7% (p < 0.05)
oPatients in the highest quartile of exposures achieved the highest response, 63.2% vIGA 0/1 and 63.2% EASI-90 at Week 16

 

 

 

 

·Treatment of patients with APG777 led to rapid onset of itch relief and achieved statistically significant reduction by Week 1
o50.7% reduction of Itch NRS from baseline compared to 23.2% (p < 0.01)

 

·APG777 was well tolerated with a safety profile consistent with other agents in the class
o56.1% of APG777-exposed patients experienced treatment-emergent adverse events (“TEAEs”) (vs. 63.4% in placebo)
oSerious TEAEs were rare for APG777-exposed patients (1.2% vs. 2.4% in placebo)
oDiscontinuation rate due to AEs was low for APG777-exposed patients (2.4%)
oThe most common TEAEs (occurring in ≥5% of patients in either treatment group) were non-infective conjunctivitis, upper respiratory tract infection, and nasopharyngitis, the latter two numerically lower in APG777 treated patients
oThere were 0 injection site reactions in the APG777 group

 

APEX Part B is a placebo-controlled dose optimization with approximately 280 patients randomized 1:1:1:1 to high, medium, or low dose APG777 versus placebo. Part B continues to enroll participants with 16-week readout expected in mid-2026, expected to enable initiation of a Phase 3 trial in 2026 and anticipated commercial launch this decade, subject to regulatory alignment. Data readout from the maintenance phase of APEX Part A, testing 3- and 6-month maintenance dosing, is expected in the first half of 2026.
