New vaginal tablet could ease menopause discomfort
NCT ID NCT06197568
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a vaginal tablet called AZU-101 (lasofoxifene) in 90 postmenopausal women aged 45-60 who have vaginal atrophy, causing dryness and pain during sex. The tablet is given daily for 14 days to see if it is safe and can improve vaginal cell health and lower vaginal pH. Half the participants will get the active drug and half a placebo, and neither they nor the doctors will know which they received.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lasofoxifene tartrate (AZU-101) vaginal tablet
- What this could lead to
- If successful, this could provide a new, locally-acting treatment option for vaginal atrophy that eases discomfort and improves quality of life in postmenopausal women.
- What could go wrong
- This is an early Phase 2 proof-of-concept study with only 90 participants. The treatment may not prove effective or safe enough to advance, and side effects are still being evaluated.
