Plain English Summary
Background and study aims
Endometriosis is a condition where small pieces of the womb lining (the endometrium) are found outside the womb. Uterine fibroids are non-cancerous growths that develop in or around the womb. The ideal treatment for endometriosis and uterine fibroids would lower the female sex hormone estrogen, whilst avoiding the menopausal flushing and bone loss associated with current treatments. Substance P and neurokinin B bind to the neurokinin (NK) receptors 1 and 3, respectively, to control reproductive hormone levels. NT-814 is a new, non-hormonal treatment which blocks the NK 1,3 receptors. However, the effects of NT-814 on reproductive hormone levels in healthy women is currently unknown. Current treatments for hormone-driven disorders, such as endometriosis and uterine fibroids, are limited by side effects and effectiveness. The aim of this study is to assess the effectiveness and safety of NT-814 in healthy women.
Who can participate?
Healthy women aged 18-45 with regular menstrual cycles, not taking any medications or hormonal contraception
What does the study involve?
Healthy women attend for two consecutive menstrual cycles. No treatment is given in Cycle 1. During Cycle 2, women are randomly allocated to receive placebo (dummy drug) or NT-814 40 mg, 80 mg or 120 mg for up to 21 days. In each cycle, blood samples are taken on days 3/4, 9/10, 15/16 and 21/22 to measure blood reproductive hormone levels.
What are the possible benefits and risks of participating?
Regular monitoring (using blood samples, clinical observations and ECG) are used throughout to maintain participant safety.

Study information
Scientific title
A randomized, single-blind, placebo-controlled study of the effects of repeat doses of NT-814 on oestradiol and other sex hormone concentrations in healthy pre-menopausal female volunteers
Acronym
Study hypothesis
NT-814 is a dual NK1,3 receptor antagonist and therefore has the theoretical potential to reduce GnRH pulsatility by blocking the endogenous effects of NKB and substance P on the reproductive axis. This would lower LH levels and subsequently estradiol concentrations in healthy pre-menopausal women.

Condition
Reproductive hormone levels in women with hormone-driven disorders
Intervention
This is a Phase 1, randomized, single-blind, placebo-controlled study designed to determine the effects of NT-814 (40, 80, 120, 160 mg once daily) on GnRH pathway hormones in healthy female subjects.
Thirty-two healthy women attend for two consecutive menstrual cycles. In each cycle, blood samples are taken on days 3/4, 9/10, 15/16 and 21/22 to measure serum reproductive hormone levels, and plasma NT-814 levels (Cycle 2 only). No treatment is given in Cycle 1 (baseline). During Cycle 2, participants are randomized by block randomization to receive placebo or NT-814 40 mg, 80 mg or 120 mg (n=8 per group) for up to 21 days.

Drug
Phase
Phase I
Drug names
NT-814: a novel, non-hormonal NK1,3 antagonist
Primary outcome measure
GnRH pathway hormones measured using serum LH, FSH, oestradiol and progesterone concentrations on Days 3/4, 9/10, 15/16 and 21/22 in both Cycle 1 (baseline) and Cycle 2 (treatment)
Secondary outcome measures
1. The safety of NT 814 measured using clinical laboratory assessments (haematology and biochemistry), vital signs (BP and HR), and recording of treatment-emergent adverse events on Days 3/4, 9/10, 15/16 and 21/22 in both Cycle 1 (baseline) and Cycle 2 (treatment)
2. The PK-PD relationship of NT-814 measured using NT-814 plasma concentration levels during Cycle 2 Days 3/4, 9/10, 15/16 and 21/22
3. Menstrual cycle length measured using the difference in cycle length (in days) between Cycle 1 and Cycle 2
