Core offering

Elion Therapeutics is a clinical-stage biotechnology company developing Turletricin (EL219/SF001), a next-generation polyene antifungal drug designed for IV infusion to treat life-threatening invasive fungal infections. The drug is engineered via rational drug design to preferentially extract fungal ergosterol over human cholesterol, reducing the nephrotoxicity associated with conventional amphotericin B therapy while delivering broad-spectrum activity against Candida, Aspergillus, Cryptococcus, Fusarium, and Coccidioides species.

Product overview

Elion Therapeutics is a biotechnology company developing a single core product: Turletricin (also known as EL219 or SF001), a next-generation polyene antifungal drug. This novel polyene therapy is designed as a safer alternative to amphotericin B, addressing critical unmet needs in treating invasive fungal infections. The product is currently in Phase 2 clinical development and has received FDA QIDP and Fast Track designations.

Partnerships

One partnership is on record.

• University of IllinoisfoundationalStrategic or Co-development PartnerResearchers at the University of Illinois discovered the 'sponge model' mechanism that enables amphotericin B to extract sterols from cell membranes. This foundational scientific discovery informed the rational drug design approach that led to Elion's development candidate EL219. The technology was published in Nature.

Recent moves6 records

Expansion highlights5 records

Emerging players

• Seres Therapeutics: While not directly in antifungals, Seres is a clinical-stage infectious disease/microbiome company that has applied for and received FDA QIDP and other infectious disease regulatory designations. Its experience navigating similar regulatory pathways and clinical-stage infectious disease development makes it a relevant emerging comparator for Elion's commercialization trajectory.
• Matinas BioPharma Holdings: Matinas is a clinical-stage biotech that has explored antifungal applications leveraging its lipid nanocrystal delivery platform. While its primary programs have shifted, it remains an emerging comparator in the antifungal development space with similar early-stage dynamics.

Broad incumbents

• Astellas Pharma: Astellas markets micafungin (Mycamine), an echinocandin antifungal used for invasive candidiasis and aspergillosis, and has a track record in hospital mycology. As a large pharma with an established antifungal franchise, Astellas is a relevant broad incumbent comparable to Elion's positioning.
• Gilead Sciences: Gilead historically marketed AmBisome, the leading liposomal amphotericin B product, and remains a broad incumbent in hospital antifungals. Its established hospital channel and existing amphotericin franchise make it a key comparable and potential strategic acquirer for differentiated polyene programs like EL219.
• Pfizer: Pfizer markets the triazole antifungal isavuconazole (Cresemba) and acquired Amplyx's fosmanogepix program, making it a broad incumbent in the antifungal space. As a large pharma with established hospital sales infrastructure, Pfizer represents both a competitive threat and a potential acquirer of antifungal-focused assets like Elion's EL219.

Direct peers

• Mycovia Pharmaceuticals: Mycovia developed oteseconazole (Vivjoa) for recurrent vulvovaginal candidiasis and advanced programs in invasive fungal infections. Its antifungal-focused pipeline and clinical-stage profile make it a direct comparable to Elion's positioning around invasive and difficult-to-treat fungal disease.
• Amplyx Pharmaceuticals: Amplyx developed fosmanogepix, a novel antifungal Gwt1 inhibitor targeting invasive fungal infections including aspergillosis and rare molds. Its focus on hard-to-treat invasive fungal infections closely mirrors Elion's therapeutic focus, and following acquisition-related activity it remains a relevant comparable program.
• Basilea Pharmaceutica: Basilea develops and commercializes the antifungal isavuconazole (Cresemba, ex-US) through partnerships and has historically developed other hospital antifungals including echinocandins. Its antifungal-focused pipeline targeting invasive mold and yeast infections makes it a relevant direct comparable to Elion.
• Scynexis: Scynexis developed and commercialized ibrexafungerp (Brexafemme), a first-in-class triterpenoid antifungal approved for vulvovaginal candidiasis with clinical programs in invasive fungal infections. As an antifungal-focused company with overlapping mechanism and indication ambitions, it is a direct comparator to Elion.
• Cidara Therapeutics: Cidara Therapeutics is a clinical-stage biotech developing antifungal therapeutics, including the FDA-approved echinocandin rezafungin (Rezzayo) for candidemia and invasive candidiasis. It is a direct competitor to Elion in the invasive fungal infection space, targeting similar hospital-treated patient populations with novel mechanisms.
