Ibrexafungerp Versus Placebo for Vulvovaginal Candidiasis Treatment: A Phase 3, Randomized, Controlled Superiority Trial (VANISH 303).

BACKGROUND: Current treatment of vulvovaginal candidiasis (VVC) is largely limited to azole therapy. Ibrexafungerp is a first-in-class triterpenoid antifungal with broad-spectrum anti-Candida fungicidal activity. The objective of this study was to evaluate the efficacy and safety of ibrexafungerp compared with placebo in patients with acute VVC. METHODS: Patients were randomly assigned 2:1 to receive ibrexafungerp (300 mg twice for 1 day) or placebo. The primary endpoint was the percentage of patients with a clinical cure (complete resolution of vulvovaginal signs and symptoms [VSS] = 0) at test-of-cure (day 11 ± 3). Secondary endpoints included the percentage of patients with mycological eradication, overall success (clinical cure and mycological eradication), clinical improvement (VSS ≤ 1) at test-of-cure, and symptom resolution at follow-up (day 25 ± 4). RESULTS: Patients receiving ibrexafungerp had significantly higher rates of clinical cure (50.5% [95/188] vs 28.6% [28/98]; P = .001), mycological eradication (49.5% [93/188] vs 19.4% [19/98]; P < .001), and overall success (36.0% [64/178] vs 12.6% [12/95]; P < .001) compared with placebo. Symptom resolution was sustained and further increased with ibrexafungerp compared with placebo (59.6% [112/188] vs 44.9% [44/98]; P = .009) at follow-up. Post hoc analysis showed similar rates of clinical cure and clinical improvement at test-of-cure for Black patients (54.8% [40/73] and 63.4% [47/73], respectively) and patients with a body mass index >35 (54.5% [24/44] and 68.2% [30/44], respectively) compared with overall rates. Ibrexafungerp was well tolerated. Adverse events were primarily gastrointestinal and mild in severity. CONCLUSIONS: Ibrexafungerp provides a promising safe and efficacious oral treatment that mechanistically differs from current azole treatment options for acute VVC.

Efficacy and safety of ospemifene in postmenopausal women with moderate-to-severe vaginal dryness: a phase 3, randomized, double-blind, placebo-controlled, multicenter trial.

OBJECTIVE: To evaluate the safety and efficacy of ospemifene for the treatment of moderate to severe vaginal dryness in postmenopausal women with vulvovaginal atrophy (VVA). METHODS: This 12-week, multicenter, double-blind phase 3 study randomized postmenopausal women (aged 40-80 years) with VVA and moderate to severe vaginal dryness as their most bothersome symptom to daily oral ospemifene 60 mg or placebo. Coprimary efficacy endpoints included changes from baseline to week 12 in percentages of vaginal parabasal and superficial cells, vaginal pH, and vaginal dryness severity with ospemifene versus placebo; other secondary endpoints were evaluated (weeks 4, 8, and 12). Safety was assessed by treatment-emergent adverse events (TEAEs) and endometrial biopsies. RESULTS: Women (n = 631; ospemifene [n = 316], placebo [n = 315]) had a mean age of 59.8 years, a mean body mass index of 27.2 kg/m, and most were white. Ospemifene significantly improved (P < 0.0001) the percentages of parabasal and superficial cells, vaginal pH, and severity of vaginal dryness severity compared with placebo at week 12; significant between-group differences were noted by week 4. Secondary endpoints of dyspareunia (P < 0.001), maturation value (P < 0.0001), and the Female Sexual Function Index (P < 0.05) also significantly improved with ospemifene versus placebo at week 12. Significantly more women responded (31.5% vs 6.0%; P < 0.0001) or were satisfied (49.2% vs 33.8%; P = 0.0007) with ospemifene versus placebo at week 12. No unexpected TEAEs, treatment-related serious TEAEs, thrombotic events, or endometrial hyperplasia or carcinoma were observed. CONCLUSIONS: Ospemifene was effective and well tolerated for the treatment of moderate-to-severe vaginal dryness in postmenopausal women with VVA.
