A Regulatory Review Approach for Evaluation of Micafungin for Treatment of Neonatal Candidiasis.

Pathogenesis of neonatal candidiasis (NC) is distinct from systemic candidiasis in adults and older pediatric patients due to the significant incidence of central nervous system involvement in neonates. Thus, although adequate and well-controlled trials in NC are often unfeasible due to difficulty enrolling patients, extrapolation of efficacy from antifungal drug trials in adults is generally not appropriate. However, treatment of NC is an area of great unmet need. We describe a regulatory review approach that combined the assessment of limited clinical efficacy, pharmacokinetics, and safety data from neonates and young infants along with microbiology outcomes and pharmacokinetic data from relevant nonclinical models of candidemia/invasive candidiasis to inform the use of micafungin in pediatric patients younger than 4 months, while communicating areas of remaining uncertainty in labeling.

Worldwide, neonatal mortality corresponds to 41% of those that occur in children under five years of age. Among the causes described by WHO, sepsis corresponds to the third, after prematurity and perinatal asphyxia. Candida sp is one of the etiological agents that in the neonatal period generates high morbidity and mortality, as well as long-term neurological sequelae, especially in premature and low birth weight. These patients have their own immunological characteristics, requirements for invasive procedures and greater survival in prolonged hospital stays, which become risk factors that predispose to develop systemic candidiasis. Given the impact of this pathology, it is important to have a comprehensive diagnostic and therapeutic approach that reduces morbidity and mortality, improving vital and functional prognosis. In recent years, different medical guidelines and protocols have been generated in order to optimize the management of this infection, so it is important to describe what are the best current recommendations for the approach, diagnosis and treatment of neonatal candidiasis.

High-dose liposomal amphotericin B in the therapy of systemic candidiasis in neonates.

High-dose (5-7 mg/kg/day) liposomal amphotericin B was evaluated prospectively during the period 1995-2001 in 41 episodes of systemic candidiasis occurring in 37 neonates (36 of the 37 were premature infants with very low birth weights). Median age at the onset of systemic candidiasis was 17 days. Candida spp. were isolated from blood in all patients and from urine, skin abscesses and peritoneal fluid in 6, 5 and 1 neonates, respectively. Candidiasis was due to Candida parapsilosis in 17 cases, Candida albicans in 15 cases, Candida tropicalis in 5 cases, Candida guilliermondii in 2 cases, Candida glabrata in 2 cases and an unidentified Candida sp. in 1 case. Twenty-eight, five and eight infants received 7, 6-6.5 and 5 mg/kg/day, respectively. Median duration of therapy was 18 days; median cumulative dose was 94 mg/kg. Fungal eradication was achieved in 39 of 41 (95%) episodes; median duration of therapy until fungal eradication was 8.7+/-4.5 days. Fungal eradication was achieved after 10.9+/-4.8 days in patients who had received previous antifungal therapy compared to 8.2+/-4.3 days in those treated with liposomal amphotericin B as first-line therapy. One patient died due to systemic candidiasis on day 12 of therapy. High-dose liposomal amphotericin B was effective and safe in the treatment of neonatal candidiasis. Fungal eradication was more rapid in patients treated early with high doses and in patients who received high-dose liposomal amphotericin B as first-line therapy.
