Rhea-AI Filing Summary

Cidara Therapeutics (Nasdaq: CDTX) filed an 8-K disclosing positive topline data from its randomized, double-blind, placebo-controlled Phase 2b NAVIGATE study of CD388 for the prevention of seasonal influenza in 18-64-year-old healthy, unvaccinated adults.

The trial’s primary endpoint was met across all three single-dose cohorts, delivering statistically significant prevention efficacy (PE): 57.7% at 150 mg, 61.3% at 300 mg and 76.1% at 450 mg versus a 2.8% infection rate in placebo. All secondary endpoints—including efficacy at ≥37.8 °C and ≥37.2 °C fever thresholds and durability to week 28—also achieved statistical significance. CD388 was well-tolerated; no drug-related serious adverse events or unexpected dose-limiting toxicities were observed, and injection-site reactions were comparable to placebo.

Cidara has requested an End-of-Phase 2 meeting with the FDA to review the data and discuss Phase 3 design and timing. Additional NAVIGATE results will be presented at scientific conferences later in 2025. Management will host a conference call and webcast on 23 June 2025; supporting slides are furnished as Exhibit 99.1.

Cidara Therapeutics (Nasdaq: CDTX) ha presentato un modulo 8-K comunicando dati positivi di topline dal suo studio randomizzato, in doppio cieco e controllato con placebo di fase 2b NAVIGATE su CD388 per la prevenzione dell'influenza stagionale in adulti sani non vaccinati di età compresa tra 18 e 64 anni.

L'end point primario dello studio è stato raggiunto in tutti e tre i gruppi a dose singola, mostrando un'efficacia preventiva statisticamente significativa (PE): 57,7% a 150 mg, 61,3% a 300 mg e 76,1% a 450 mg rispetto a un tasso di infezione del 2,8% nel gruppo placebo. Tutti gli end point secondari — inclusa l'efficacia alle soglie di febbre ≥37,8 °C e ≥37,2 °C e la persistenza fino alla settimana 28 — hanno anch'essi raggiunto significatività statistica. CD388 è stato ben tollerato; non sono stati osservati eventi avversi gravi correlati al farmaco né tossicità limitanti inattese, e le reazioni nel sito di iniezione erano comparabili al placebo.

Cidara ha richiesto un incontro di fine fase 2 con la FDA per rivedere i dati e discutere il disegno e i tempi della fase 3. Ulteriori risultati dello studio NAVIGATE saranno presentati in conferenze scientifiche nel corso del 2025. La direzione terrà una conference call e una webcast il 23 giugno 2025; le slide di supporto sono fornite come Exhibit 99.1.

Cidara Therapeutics (Nasdaq: CDTX) hat einen 8-K-Bericht eingereicht, der positive Zwischenergebnisse aus der randomisierten, doppelblinden, placebokontrollierten Phase-2b-Studie NAVIGATE mit CD388 zur Prävention der saisonalen Influenza bei gesunden, ungeimpften Erwachsenen im Alter von 18 bis 64 Jahren offenlegt.

Der primäre Endpunkt der Studie wurde in allen drei Einzeldosis-Kohorten erreicht und zeigte eine statistisch signifikante Präventionseffizienz (PE): 57,7 % bei 150 mg, 61,3 % bei 300 mg und 76,1 % bei 450 mg im Vergleich zu einer Infektionsrate von 2,8 % im Placebo. Alle sekundären Endpunkte – einschließlich Wirksamkeit bei Fieberschwellen von ≥37,8 °C und ≥37,2 °C sowie Dauerhaftigkeit bis Woche 28 – erreichten ebenfalls statistische Signifikanz. CD388 wurde gut vertragen; es traten keine schwerwiegenden arzneimittelbedingten Nebenwirkungen oder unerwartete dosislimitierende Toxizitäten auf, und Injektionsstellenreaktionen waren mit Placebo vergleichbar.

Cidara hat ein Ende-Phase-2-Meeting mit der FDA beantragt, um die Daten zu überprüfen und das Design sowie den Zeitplan der Phase 3 zu besprechen. Weitere NAVIGATE-Ergebnisse werden im Laufe des Jahres 2025 auf wissenschaftlichen Konferenzen präsentiert. Das Management wird am 23. Juni 2025 eine Telefonkonferenz und ein Webcast veranstalten; unterstützende Folien sind als Exhibit 99.1 beigefügt.

Positive
  • Phase 2b NAVIGATE trial met primary and all secondary endpoints, showing up to 76.1% prevention efficacy versus placebo (p < 0.0001).
  • CD388 exhibited a clean safety profile with no drug-related serious adverse events or unexpected toxicities across all dose groups.
  • Cidara submitted an End-of-Phase 2 FDA meeting request, advancing CD388 toward a Phase 3 pivotal study.
Negative
  • None.

Insights

TL;DR: Robust efficacy and clean safety data de-risk CD388, positioning CDTX for Phase 3 and potential strategic interest.

The filing signals a material clinical milestone. Prevention efficacy above 60% across doses—peaking at 76%—beats the historical bar set by standard flu vaccines in healthy adults and is clinically meaningful. The absence of serious safety signals mitigates one of the principal development risks for systemic antiviral prophylaxis. A prompt FDA End-of-Phase 2 meeting request indicates management’s intent to accelerate timelines; successful alignment could place Phase 3 enrollment in the 2025-26 flu season. These outcomes strengthen CDTX’s negotiating leverage for partnership or non-dilutive funding and could expand the drug’s addressable market beyond high-risk populations. Investors should monitor cash runway and Phase 3 trial size, but near-term sentiment is clearly positive.

TL;DR: Efficacy across fever thresholds confirmed; safety profile supports larger pivotal studies, but elderly data still absent.

The dataset is technically solid: randomized design, >470 evaluable subjects, and rigorous RT-PCR confirmation elevate reliability. PE confidence intervals remain wide at lower doses, yet the grouped 300 mg + 450 mg analysis (68.6% PE; p<0.0001) underpins dose-selection optionality. Duration of protection to week 28 addresses a key unmet need for long-season coverage. Importantly, the filing does not include immunogenicity correlates or data in adults >65, the group with highest flu morbidity; regulators may require these in Phase 3. Still, the clean tolerability profile—no dose-dependent adverse-event gradient—simplifies pivotal trial risk management. Overall, the clinical risk profile has improved, though commercial upside depends on replicating results in older and co-morbid populations.
