TX-004HR clinically improves symptoms of vulvar and vaginal atrophy in postmenopausal women

Climacteric. 2019 Aug;22(4):412-418. doi: 10.1080/13697137.2019.1577379. Epub 2019 Mar 12.


Objective: This study aimed to evaluate improvement of dyspareunia and associated vaginal dryness with a 17β-estradiol softgel vaginal insert (TX-004HR; TherapeuticsMD, Boca Raton, FL, USA) in women with postmenopausal vulvar and vaginal atrophy (VVA). Methods: Postmenopausal women with VVA and moderate to severe dyspareunia received TX-004HR (4, 10, or 25 μg) or placebo in the 12-week, randomized, double-blind, placebo-controlled, phase 3 REJOICE trial. Post hoc analyses examined improvement levels in dyspareunia and concurrent vaginal dryness with TX-004HR and assessed the effects of patient characteristics on vaginal dryness treatment. Results: Significantly more women treated with TX-004HR (all doses) than placebo had complete resolution or substantial improvement in dyspareunia or vaginal dryness (concurrent with dyspareunia) by 12 weeks, observed as early as week 2 with most doses. TX-004HR significantly improved both dyspareunia and vaginal dryness at least one level versus placebo by week 12 in women with both symptoms. Subgroup analyses showed TX-004HR improved vaginal dryness associated with dyspareunia regardless of age, body mass index, uterine status, prior pregnancy, and vaginal birth number. Conclusion: TX-004HR provided clinically meaningful improvements in dyspareunia and vaginal dryness associated with dyspareunia in postmenopausal women with VVA. Clinicians may be able to use this information when discussing patients' expectations regarding symptom improvement with the estradiol vaginal insert.
