Comparing EL219 with Active Comparator- for invasive mould infection

Official title: Phase 2 EL219 Versus Liposomal Amphotericin B or Voriconazole for Early Antifungal Therapy

A Phase 2, Multicenter, Randomized, Double-blind Study of Safety and Efficacy of EL219 (Turletricin) Versus Liposomal Amphotericin B or Voriconazole for Early Antifungal Therapy of Invasive Mould Infections (TREAT-1)

Condition: Invasive Mould InfectionSponsor: Elion Therapeutics, Inc.Target enrollment: 60

Interventions

  • Medication

    EL219

    EL219 is specifically being developed for early antifungal therapy (EAT), when infection is suspected due to highly suggestive signs and symptoms of disease; in high-risk people, antifungals are recommended even before confirmation of the microbial cause of infection, because delayed therapy is associated with poor outcomes in those who lack adequate immune responses. EL219 may provide a once-weekly alternative to LAmB and other polyenes that could also reduce the toxicities that often limit the frequency and duration of administration for these highly efficacious antifungals.

  • Medication

    Active Comparator- IV Antifungal (LAmB or voriconazole)

    LAmB has broad-spectrum activity but its use is limited by toxicity and once-daily IV administration. It is not administered outside of the monitored setting given risks for electrolyte disturbances and cardiac arrhythmias. Voriconazole is a first-line therapy for IA and the most common azole used in the US and globally but does not have activity against many non-Aspergillus moulds.
