The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01114126
Recruitment Status : Completed

Brief Summary:
The primary objective of the study is to evaluate the safety and tolerability of Neu-P11, following the administration of multiple ascending oral doses (2, 5, 20, 50 mg or matching placebo) given nightly over 2 periods of 5 days to male and female subjects with primary insomnia. In addition, the study is aimed to determine the pharmacokinetic profile of Neu-P11 after 1 and 5 days of administration and to evaluate the hypnotic effects of Neu-P11 as well as the effects on mood and memory. The study hypothesis is that Neu-P11 is safe, tolerated and have significant sleep promoting effects.

Condition or disease Intervention/treatment Phase
Insomnia Drug: Neu-P11 Drug: Neu-P11 placebo Phase 1

Detailed Description:
The effects of four multiple ascending doses of orally administered Neu-P11 will be evaluated in a double- blind, placebo-controlled, crossover design. Following a screening visit, the recruited subjects will undergo an inclusion/habituation full night PSG screening recording in the sleep clinic to exclude subjects with sleep disorders. Eligible subjects will be divided into 2 cohorts of 12 subjects each. Following screening, each cohort will be randomised to receive Neu-P11 or placebo for a first period of 5 days and will be crossed over following at least 21 days to receive placebo or a higher dose of Neu-P11 for a second period of 5 days. Each cohort will receive a different dose of Neu-P11, chosen from 2, 5, 20 and 50 mg. The starting dose is 5 mg but a smaller dose (2 mg) is also included for the purpose of pharmacodynamic evaluation. Before proceeding from 5mg to the next higher dose safety will be evaluated based on adverse events, clinical and biological data. Subjects of Cohort A will be randomised to dose levels 2 and 3 (doses 5 and 20 mg). Subjects of Cohort B will be randomised to dose levels 1 and 4 (doses 2 and 50 mg).

Primary Outcome Measures :
  1. Number and description of participants with adverse events [ Time Frame: 5 days ]
    adverse events will be recorded and reported throughout the study

Secondary Outcome Measures :
  1. Neu-P11 concentration, exposure and clearance [ Time Frame: 5 days ]

    To learn about the concentration, exposure and clearence of to Neu-P11 Pharmacokinetic(PK)parameters will be recorded and reported:

    • Blood samples for Neu-P11 and metabolites plasma concentration determination will be drawn on several time points at the beginning and at the end of each period
    • Urine samples for Neu-P11 and metabolites determination will be collected on several time points at the beginning and at the end of each period.

  2. Objective and subjective assessment sleep quality [ Time Frame: 5 days ]

    PSG parameters (sleep time, efficiency and architecture) as an objective assessment of sleep quality will be recorded

    Subjective means of evaluation of sleep qulity will include:

    • Sleep Diary (NSFSD).
    • sleepiness scale (KSS)

  3. Subjective evaluation of mood and emotions [ Time Frame: 5 days ]

    To study the effect of Neu-P11 on mood and emotions, subjective evaluation of mood and emotions will be recorded and reported using:

    • Profile of Mood States (POMS).
    • Emotional-visual analogue scale (e-VAS).

Ages Eligible for Study:   18 Years to 65 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Primary insomnia male or female subjects according to DSM-IV criteria (307.42) ,
  2. Sleep latency of > 30 minutes and total sleep time < 6 hrs based on Sleep History Questionnaire (SHQ) and verified by the inclusion + habituation night PSG,
  3. Men or women 18 to 65 years inclusive,
  4. Women of childbearing potential must have a negative pregnancy test at the screening visit, on Day 1 of each treatment period, and use a reliable method of contraception during the entire study duration and for at least 3 months after study drug intake. Reliable methods of contraception are:

    • Double barrier type devices (e.g., male or female condom, diaphragm, contraceptive sponge) only in combination with a spermicide.
    • Intra-uterine devices in combination with a spermicide. Abstention, rhythm method, and contraception by the partner alone are not acceptable methods of contraception. Women not of childbearing potential are defined as postmenopausal (i.e., amenorrhea for at least 1 year), or surgically or naturally sterile.
  5. Subjects must be in good health as determined by their medical history, physical examination, ECG, vital signs, standard EEG, serum biochemistry, haematology and urinalysis. A subject with clinical abnormality may be included only if the investigator or his designee considers that the abnormality will not introduce additional risk factor for the subject's health, or interfere with the study objectives,
