Plain English Summary

Background and study aims:
Kisspeptin is a hormone which acts as the master regulator of reproductive hormone release in humans. Clinical studies demonstrate that intravenous (into a vein) or subcutaneous (under the skin) kisspeptin administration could be used to treat reproductive disorders. A non-invasive delivery route would be preferable to patients and clinicians. To address this, the aim of this study is to find out whether intranasal administration (snorting) of kisspeptin can stimulate reproductive hormone release in healthy volunteers and patients with reproductive disorders.

Who can participate?
Healthy men and women and patients with reproductive disorders, aged 18 – 70 years

What does the study involve?
Participants will attend at least two study visits at least 1 week apart at the Clinical Research Unit (Charing Cross Hospital, London). At one visit kisspeptin will be self-administered using a nasal spray device and at the other visit a placebo (dummy drug) will be used instead. Blood samples will be collected through a cannula (tube) every 15 minutes for 4 hours to measure reproductive hormone release.

What are the possible benefits and risks of participating?
Kisspeptin is a naturally occurring hormone which has been given to over 500 men and women without complications or side effects. The main benefit will be to help develop a future treatment for patients with reproductive disorders.

When is the study starting and how long is it expected to run for?
June 2017 to April 2024

Who is funding the study?
1. Medical Research Council (MRC) (UK)
2. National Institute for Health Research (NIHR) (UK)

Scientific titleInvestigating the effects of intranasal kisspeptin administration on reproductive hormone secretion
Study hypothesisIntranasal kisspeptin administration stimulates reproductive hormone secretion in healthy volunteers and patients with common reproductive disorders.
Ethics approval(s)Approved 12/10/2017, London Riverside Research Ethics Committee (Chelsea & Westminster Hospital, 369 Fulham Road, London, SW10 9NH, UK; +44 (0)20 7104 8112; riverside.rec@hra.nhs.uk), REC ref: 17/LO/1504
ConditionReproductive disorders
InterventionRandomised, placebo-controlled, cross-over study in healthy volunteers (men and women) and patients with common reproductive disorders (including hypothalamic amenorrhoea). Following self-administration of intranasal kisspeptin (dose range 3.2 to 25.6 nmol/kg) or placebo using a nasal spray device, serum reproductive hormones are measured every 15 minutes for 4 hours. Study visits will be at least 1 week apart to ensure washout, with the order of the interventions randomised (using https://www.randomizer.org).
Intervention typeDrug
Pharmaceutical study type(s)
PhasePhase I
Drug / device / biological / vaccine name(s)Kisspeptin-54
Primary outcome measureBlood levels of reproductive hormones (kisspeptin, luteinizing hormone, follicle stimulating hormone, testosterone [men] and oestradiol/progesterone [women]) measured using automated chemiluminescent immunoassays at baseline and every 15 minutes for 4 hours
Secondary outcome measures1. Safety monitoring: heart rate, blood pressure, and the presence of adverse symptoms measured using automated blood pressure monitor every 15 minutes for 4 hours
2. Behavioural parameters of reproductive behaviour assessed using validated psychometric questionnaires (including the Sexual Arousal and Desire Inventory, Positive and Negative Affect Schedule, and State-Trait-Anxiety-Inventory) at baseline and every hour until 4 hours
