Study Details

Brief summary:

Cryptococcal meningitis is a fungal infection that causes a severe syndrome of meningitis that is 100% fatal without antifungal therapy. Even with antifungal therapy, mortality rates remain high, especially in low and middle income countries where the ongoing HIV/AIDS pandemic increases the risk of cryptococcosis among persons living with HIV infection. The combination of amphotericin and flucytosine (5-FC) has been the mainstay of therapy for the initial management of cryptococcal meningitis for 4 decades. Indeed, the effective delivery of these first line therapy in Africa can lower mortality to 25%. However, several challenges exist. First, even while 5-FC is included on the WHO list of essential medicines, the availability of 5-FC worldwide is limited. Second, liposomal amphotericin (Ambisome ®) is currently available from a single source supplier, creating risk. Third, current therapies have substantial toxicity. Lastly, with widespread agricultural fungicide use of azoles, the median fluconazole minimum inhibitory concentration (MIC50 ) for Cryptococcus has doubled since 2013. Globally, new or improved antifungals are needed for cryptococcal meningitis, particularly those which have less toxicity, greater efficacy, a prolonged half-life, and minimal drug-drug interactions. As multiple new antifungal medicines are on the horizon, this platform trial utilizes a master protocol to investigate, multiple regimens using standardized eligibility criteria, standardized study schedule of events, and standardized contemporary endpoints.

Interventions

Standard of care

2022 WHO First Line Induction Therapy:

1. Liposomal Amphotericin B 10mg/kg IV given once
2. Flucytosine 100mg/kg/day for 14 days in divided doses
3. Fluconazole 1200mg/day for 14 days Consolidation Therapy: Fluconazole 800mg/day from 2 to 10 weeks Secondary Prophylaxis: Fluconazole 200mg/day through 1 year minimum

Oteseconazole - antifungal therapy 1

Oteseconazole, is an azole metalloenzyme inhibitor targeting the fungal sterol, 14α demethylase (CYP51)

  • Loading doses of oral Oteseconazole 600 mg twice daily for 10 days, then 600 mg oteseconazole weekly on weeks 3, 4, 5, and 6.
  • Liposomal Amphotericin B 10 mg/kg IV once.
  • No fluconazole or 5FC to be given.

Sfu-AM2-19 Injection - antifungal therapy 2

Ambisome 10 mg/kg IV administered once Fluconazole 1200mg/day and flucytosine 100mg/day in divided doses x 14 days OR SF001 1.5 mg/kg IV administered on day 1, followed by 1.5 mg/kg on day 8 Fluconazole 1200mg/day and flucytosine 100mg/day in divided doses x 14 days OR SF001 2.0 mg/kg IV administered on day 1, followed by 1.5 mg/kg on day 8 Fluconazole 1200mg/day and flucytosine 100mg/day in divided doses x 14 days
