Eumycetoma Long-term Post-Treatment Follow-Up Study

Terminated

• Conditions: Eumycetoma

• Registration Number: NCT06514183
• Lead Sponsor: Drugs for Neglected Diseases

Brief Summary

To assess the long-term recurrence rate of eumycetoma in clinical trial participants treated in the phase II DNDi-FOSR-04-MYC clinical trial.

Detailed Description

The purpose of the long-term post treatment follow-up study is to collect data on recurrence of eumycetoma lesions in participants who previously participated in: A randomized, double blind phase II proof-of-concept superiority trial of fosravuconazole 200 mg or 300 mg weekly dose versus itraconazole 400 mg daily, all three arms in combination with surgery, in participants with eumycetoma in Sudan (DNDi-FOSR-04-MYC).

These data will provide additional information on recurrences after end of study (\>15 months) of the parent clinical trial (DNDi-FOSR-04-MYC). The study is observational, since there is no intervention in this protocol, but assesses the outcome of the intervention of the parent trial.

Primary Outcome Measures

Name	Time	Method
To assess recurrence of eumycetoma lesions up to 5 years after end of treatment in participants previously treated with fosravuconazole 200 mg or 300 mg weekly or itraconazole 400 mg daily in study DNDi-FOSR-04-MYC	6 years	Population: Participants in trial DNDi-FOSR-04-MYC who had no recurrence of eumycetoma lesion before month 15; * Treatment: fosravuconazole 200 mg or 300 mg weekly or itraconazole 400 mg daily in study DNDi-FOSR-04-MYC; * Variable: Time to recurrence of eumycetoma lesion (if lesion occurred) or time followed-up without lesion

Secondary Outcome Measures

Name	Time	Method
To determine efficacy of fosravuconazole 200 mg or 300 mg monotherapy vs. itraconazole monotherapy, after long term post-treatment follow-up	15 months	Population/Treatment/Variable/Intercurrent events: as for primary estimand Hazard ratios comparing a) risk of recurrence for fosravuconazole 200mg vs. itraconazole
To assess overall recurrence of eumycetoma lesions up to 5 years in participants treated with fosravuconazole 200 mg or 300 mg weekly or itraconazole 400 mg daily in study DNDi-FOSR-04-MYC	6 years	Population: Participants in trial DNDi-FOSR-04-MYC regardless of recurrence before Month 15.; Treatment/Variable/Intercurrent events: as defined for the primary estimand
To describe the etiologic pathogen (subtype of fungus) after long term recurrence	15 months	Population: Participants with recurrence of eumycetoma within the current study Summary measure: Proportion of recurrences of each subtype; * Treatment: as for primary estimand; * Variable: Typing of fungus
