What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EL219Drug
Also called Formerly SF001, Now EL219 (Turletricin)
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.
Active Comparator- IV Antifungal (LAmB or voriconazole)Drug
Also called Liposomal Amphotericin B 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.
| Study group | Role | What they receive |
|---|---|---|
| EL219 | Experimental | Participants randomized to EL219 will receive a single loading dose of EL219 at 2 mg/kg via IV infusion on Day 1, and 1.5 mg/kg IV infusions on Days 8, 15, 22, 29, and 36. All dosing calculations for EL219 will be based on total body weight (TBW).
To maintain the blind, placebo IV infusions will be administered to participants randomized to EL219 arm daily (corresponding to Liposomal Amphotericin B (LAmB) dosing); or 2x daily (corresponding to voriconazole dosing depending on the Investigator's choice of Comparator). Receives: Drug: EL219 |
| Antifungal Comparator | Active comparator | Comparator arm (CMPTR) will receive LAmB 3mg/kg once daily IV infusions for min.14 days \& up to 42 days. Participants w/suspected or diagnosed mucormycosis may be dosed at 5mg/kg. Voriconazole (Vori) 6mg/kg BID IV loading dose on Day 1 followed by 4mg/kg IV BID thereafter. Dosing calculations for LAmB \& vori are based on TBW. Participants may switch from CMPTR to optional SOC antifungals (PI discretion) if any of these occur: Toxicity; serum creatinine 2×baseline (bsln) level or 50% reduction in GFR, Hypokalemia or hypomagnesemia not controlled with IV supplementation, increase in ALT to 3×bsln and/or total bili 3×bsln, intractable IRR •Imminent hosp discharge requiring switch from CMPTR •Intolerable clinical s/s consistent w/known drug-related effect •Dx by C\&S testing suggesting IMI not appropriately treated w/1 or both CMPTR drug Vori trough level <2.0 or >5.5mg/L for whom vori was selected as the randomized CMPTR Receives: Drug: Active Comparator- IV Antifungal (LAmB or voriconazole) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Primary Outcome/Measure All-Cause Mortality
All-cause mortality at Day 21 (plus or minus 3 days) in the Intent-to-Treat (ITT) analysis set.
Measured: From enrollment to Day 21
Primary Outcome/Measure SAE TEAE
During the blinded portion of the study, serious adverse events and treatment-emergent adverse events categorized in a tiered approach in the Safety analysis set. Tier 1 TEAEs include renal, electrolyte, hepatic, infusion-related reactions, photophobia and photosensitivity. Tier 2 includes all other TEAEs.
Measured: From enrollment to the end of treatment at Day 42
Secondary outcomes (3)
Secondary Outcome Measure-EAT Success
Early antifungal therapy (EAT) success at Day 21 (plus or minus 3 days) in the ITT analysis set defined by non-occurrence of the following: death, cessation of study antifungals for progression of IMI, and/or toxicity, missing data (classified as indeterminate but analyzed as a failure).
Measured: From enrollment through Day 21
Secondary Outcome Measure-Overall Success
Overall success at Day 42 (plus or minus 7 days) confirmed by the Data Review Committee, in the population with proven or probable IA (modified Intent-to-Treat)
Measured: From enrollment through Day 42
Secondary Outcome Measure-Participant is Alive
Participant is alive, favorable composite clinical, mycologic, and radiographic response (European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group [EORTC/MSG] criteria)
Measured: From enrollment through Day 42

| EL219Also: Formerly SF001, Now EL219 (Turletricin)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. | Drug | EL219 |
| Active Comparator- IV Antifungal (LAmB or voriconazole)Also: Liposomal Amphotericin B or VoriconazoleLAmB 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. | Drug | Antifungal Comparator |
