Platform Trial For Cryptococcal Meningitis

Sponsor: University of Minnesota

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.
