Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Neu-P11 in Subjects With Primary Insomnia

NCT ID: NCT01114126

Last Updated: 2011-04-07

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 24 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2010-04-30
• Study Completion Date: 2011-04-30

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.

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).

Eligibility Criteria

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,

6. Subjects who have not been using BZD and non-BZD hypnotics or melatoninergic drugs for the past 2 weeks or more prior to Screening,

7. Subjects who have not been using psychotropic treatments for the past 3 months or more prior to screening,

8. Subjects who have not been using any other non-psychotropic treatments for the past 2 weeks or more prior to Screening with the exception of occasional paracetamol intake (1 g per day),

9. Subjects having read and signed the informed consent form,

10. Subjects having a body mass index between 18 and 30 (extremes included),

11. Subjects having no documented hypersensitivity to exogenous melatonin or agonists,

12. Subjects who agree to completely refrain from alcohol, caffeine and tobacco during the institutionalisation periods,

13. Subjects able to take part in the whole study,

14. Subjects affiliated with, or beneficiary of, a social security system

Exclusion Criteria

1. According to DSM IV, subjects belonging to the following groups are excluded: 780.59 (breathing related sleep disorder); 307.45 (circadian rhythm sleep disorder); 307.47 (dyssomnia not otherwise specified); 780.xx (sleep disorder due to general medical condition) ,

2. Subjects suffering from insomnia secondary to other causes according to SHQ,

3. Subjects with sleep disorders detected during the PSG inclusion/habituation night, such as sleep apnea/hypopnea and periodic leg movement syndrome (with arousal) (PLMI > 15 and/or AHI > 15 per hour),

4. Subjects with known chronic infections or asthma, allergies or history of severe allergy,

5. Subjects with hypertension defined as systolic blood pressure > 180 mmHg and/or diastolic blood pressure > 100 mmHg according to two repeated measures in lying position within 10 min interval,

6. Subjects with hypotension defined as systolic blood pressure <90 mmHg and/or diastolic blood pressure < 45 mmHg according to two repeated measures in lying position within 10 min interval,

7. Subjects with foreseeable need of a treatment, whatever it is (including dental care), during the study period,

8. Subjects with positive drug screening for amphetamines, benzodiazepines, barbiturates, cannabis, cocaine morphine/opiates, methadone, tricyclics, methamphetamines (ecstasy) and codeine, or suspected to be drug or alcohol addicted,
