Ibrexafungerp effective against C. auris in two early case reports
A novel antifungal successfully eradicated Candida auris in two critically ill patients with fungemia, according to data presented in a poster session at the European Congress of Clinical Microbiology & Infectious Diseases.
The case reports, drawn from the phase 3 CARES study of the oral formulation of ibrexafungerp, demonstrated complete response to the glucan synthase inhibitor, according to Deven Juneja, MD, and his coauthors of the Max Super Specialty Hospital, New Delhi.
The first patient was an Asian male, aged 58 years, who had a previous history of diabetes and experienced a protracted ICU stay after acute ischemic stroke. He developed septic shock after aspiration pneumonia, and also experienced a popliteal thrombosis and liver, spleen, and kidney infarcts.
The patient had received empiric antibiotics with the addition of fluconazole; the antifungal was later switched to micafungin after C. auris was identified from blood cultures. Despite clinical improvement on micafungin, blood cultures remained positive for C. auris, so ibrexafungerp was started and continued for 17 days. Blood cultures became negative by day 3 of ibrexafungerp and remained negative for the follow-up period. The patient later developed Klebsiella pneumonia and died.
The second patient, an Asian female, aged 64 years, presented with a lower respiratory tract infection accompanied by fever and hypotension. She had a previous history of diabetes, hypertension, and chronic kidney disease with maintenance hemodialysis. Her fever also persisted despite antibiotics, and C. auris was isolated from her blood cultures with the subsequent initiation of ibrexafungerp. Her blood cultures were still positive at day 3 of ibrexafungerp, but negative at day 9 and 21. She completed 22 days of ibrexafungerp therapy and was asymptomatic with no evidence of C. auris recurrence at a 6-week follow-up visit.
The male patient experienced 2 days of loose stools soon after initiating ibrexafungerp; the female patient had no adverse events.
“These cases provide initial evidence of efficacy and safety of ibrexafungerp in the treatment of candidemia caused by C. auris, including in patients who failed previous therapies,” wrote Dr. Juneja and his coauthors in the late-breaking poster.
Ibrexafungerp belongs to a novel class of glucan synthase inhibitors called triterpenoids. Scynexis funded the CARES study and also is evaluating it alone or in combination with other antifungals for treatment of vulvovaginal candidiasis, invasive pulmonary aspergillosis, and refractory invasive and/or severe fungal disease.
