Keywords

Chronic pain, Opioid physical dependence

Brief summary

The primary objective of the study is to evaluate the safety of single doses of oral naldemedine in adults physically dependent on opioids.

Detailed description

A single dose of naldemedine or matching placebo will be administered orally to each cohort of 12 participants (9 treatments, 3 placebos) in the morning of Day 15 under fasted conditions. The first cohort will receive a 0.1 mg dose. Cohorts will continue to be enrolled at the next higher dose level until the highest dose level (3 mg) has been achieved or until the study is discontinued due to adverse events or Clinical Opioid Withdrawal Score of \>8. A 0.03 mg dose will also be tested. A 0.01 mg dose will be tested if 4 or more subjects experience 1 or more bowel movements within the 24 hour period post dose in the 0.03 mg dosing cohort.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Adverse EventsFrom the first dose of study drug on Day 15 up to Day 24.Severity of adverse events (AEs) was graded according to the following definitions: * Mild: The subject experiences awareness of symptoms but these are easily tolerated or managed without specific treatment * Moderate: The subject experiences discomfort enough to cause interference with usual activity, and/or the condition requires specific treatment * Severe: The subject is incapacitated with inability to work or do usual activity, and/or the event requires significant treatment measures. The relationship of the event to the study drug was determined by the investigator. A serious adverse event (SAE) is defined as any AE occurring at any dose that resulted in any of the following outcomes: death, life-threatening AE, hospitalization or prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth defect.

Baseline was defined as the average straining score of all BMs prior to receiving study drug (Day 1 to Day 15). The straining score at 24 and 48 hours post-dose was calculated as the average straining score from all bowel movements from 0 to 24 and 0 to 48 hours post-dose, respectively.

Baseline was defined as the average consistency of BMs prior to receiving study drug (Day 1 to Day 15). BM consistency at 24 hours and 48 hours post-dose was calculated as the average scores from all bowel movements from 0 to 24 and 0 to 48 hours post-dose, respectively.
Change From Baseline in Number of False Start Bowel Movements Per DayBaseline, 24 hours post-dose and 48 hours post-doseA false start was defined as any attempted, but unsuccessful bowel movement (no solid or liquid fecal material was excreted) based on the question In the past 24 hours, how many times did you try to have a bowel movement but were unsuccessful? Baseline was defined as the average number of false start BMs per day prior to receiving study drug (Day 1 to Day 15). The number of false start BMs per day at 24 hours and 48 hours post-dose was calculated as is the average number of false start BMs per day from 0 to 24 and 0 to 48 hours post-dose, respectively.
Change From Baseline in the Number of Bowel Movements With No Straining Per DayBaseline, 24 hours post-dose and 48 hours post-doseStraining during BMs was graded using the following scale: 0 = Absent; 1 = Mild; 2 = Moderate; 3 = Severe; 4 = Very Severe. A BM without straining was defined as a BM with a straining score = 0. Baseline was defined as the average number of BMs without straining per day prior to receiving study drug (Day 1 to Day 15).

Percentage of Participants With Clinical Opiate Withdrawal Scale (COWS) Score > 8 at Any Time During the StudyThe COWS assessments were performed at Screening, on Day 14, Day 15 (pre-dose and 1, 2, 3, 4, 5, 6 and 8 hours post-dose, and at unscheduled times as signs or symptoms indicate), on Days 16 and 17, and on Day 24/End of Study.The COWS assessment consisted of 11 questions which rated the severity of opiate withdrawal symptoms, including resting pulse rate, gastrointestinal upset, sweating, restlessness, pupil size, tremor, anxiety or irritability, bone or joint aches, gooseflesh skin, yawning, and runny nose or tearing. Each symptom was rated on a scale from 0 (not present) to 4 or 5 (most severe). The total score was calculated by summing the 11 individual scores and ranged from 0 (no withdrawal symptoms) to 48 (worst symptoms).
Percentage of Participants With Webster Opiate Withdrawal Scale (WOWS) Score > 8 at Any Time During the StudyThe WOWS assessment was performed at Screening, Day 14, Day 15 at pre-dose , and 24 and 48 hours post-dose and at the Follow-up/End of Study visit (Day 24).The Webster Opiate Withdrawal Scale (WOWS) assessment consisted of 7 questions which rate the severity of opiate withdrawal symptoms, including sweating, sleep, bone or joint aches, runny nose or tearing, gastrointestinal upset, anxiety or irritability and gooseflesh skin. Each symptom was rated on a scale from 0 (not present/no issues) to 4 or 5 (severe). The total score was calculated by summing the 7 individual scores and ranged from 0 (no withdrawal symptoms) to 29 (worst symptoms).

Area Under the Plasma Concentration-time Curve From Time Zero to Infinity for Naldemedine and Metabolite Nor-S-297995

The plasma concentration of naldemedine and its metabolite Nor-S-297995 were measured by liquid chromatography/tandem mass spectrometry (LC/MS/MS) method. Area under the plasma concentration versus time curve from time zero to infinity, calculated using the formula: AUC0-inf = AUC0-t + Ct/λZ where Ct was the last measurable concentration and λZ was the apparent terminal elimination rate constant.

Time frame: Blood samples were collected predose and at 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, and 72 hours post-dose.

Change From Baseline in BM Consistency

Consistency of BMs was measured using the Bristol Stool Scale, as follows: 1 = separate hard lumps like nuts; 2 = sausage shaped but lumpy; 3 = like a sausage, but with cracks on its surface; 4 = like a sausage or a snake, smooth and soft; 5 = soft blobs and with clear-cut edges; 6 = floppy pieces with ragged edges/mushy stool; 7 = watery, no solid pieces, entirely liquid. Baseline was defined as the average consistency of BMs prior to receiving study drug (Day 1 to Day 15). BM consistency at 24 hours and 48 hours post-dose was calculated as the average scores from all bowel movements from 0 to 24 and 0 to 48 hours post-dose, respectively.

Change From Baseline in the Number of Bowel Movements With No Straining Per Day

Straining during BMs was graded using the following scale: 0 = Absent; 1 = Mild; 2 = Moderate; 3 = Severe; 4 = Very Severe. A BM without straining was defined as a BM with a straining score = 0. Baseline was defined as the average number of BMs without straining per day prior to receiving study drug (Day 1 to Day 15). The number of BMs without straining per day at 24 hours and 48 hours post-dose was calculated as the average number of BMs with no straining per day from 0 to 24 hours and 0 to 48 hours post-dose, respectively.

Change From Baseline to 48 Hours Post-dose in Number of Complete Bowel Movements Per Day

A complete bowel movement (CBM) was defined as a bowel movement that resulted in a sensation of complete evacuation based on the question Did you have a feeling of complete emptying after the bowel movement? Baseline was defined as the average number of CBMs per day prior to receiving study drug (Day 1 to 15). Forty-eight hours post-dose was calculated as the average number of CBMs per day from 0 to 48 hours post-dose.

Percentage of Participants With Clinical Opiate Withdrawal Scale (COWS) Score > 8 at Any Time During the Study

The COWS assessment consisted of 11 questions which rated the severity of opiate withdrawal symptoms, including resting pulse rate, gastrointestinal upset, sweating, restlessness, pupil size, tremor, anxiety or irritability, bone or joint aches, gooseflesh skin, yawning, and runny nose or tearing. Each symptom was rated on a scale from 0 (not present) to 4 or 5 (most severe). The total score was calculated by summing the 11 individual scores and ranged from 0 (no withdrawal symptoms) to 48 (worst symptoms).

Time frame: The COWS assessments were performed at Screening, on Day 14, Day 15 (pre-dose and 1, 2, 3, 4, 5, 6 and 8 hours post-dose, and at unscheduled times as signs or symptoms indicate), on Days 16 and 17, and on Day 24/End of Study.
