What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion of Subjects Who Receive and Tolerate a VIVITROL Injection
Time Frame: 1 week
Toleration to the injection was demonstrated by mild opioid withdrawal symptoms (Clinical Opiate Withdrawal Scale [COWS] </=12 or Subjective Opiate Withdrawal Scale [SOWS] </=10) following VIVITROL administration. The COWS is a clinician-rated questionnaire designed to measure 11 common opioid withdrawal signs or symptoms. The summed score provides information about the level of physical dependence on opioids. The range of COWS scores is 0-4 (none to minimal); 5-12 (mild); 13-24 (moderate); 25-36 (moderately severe); and 37-48 (severe withdrawal. The SOWS is a 16-item self-report questionnaire designed to measure the severity of opioid withdrawal symptoms. The subject rates the intensity of symptoms using a 5-point scale. The range of SOWS scores is 1-10 (mild); 11-20 (moderate); and 21-30 (severe).
1 week

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion of Days With COWS Peak Score of Less Than or Equal to 12 During the Treatment Period Prior to the VIVITROL Injection
Time Frame: 1 week
The Clinical Opiate Withdrawal Scale (COWS) is a clinician-rated questionnaire designed to measure 11 common opioid withdrawal signs or symptoms. The summed score provides information about the level of physical dependence on opioids. The range of COWS scores is 0-4 (none to minimal); 5-12 (mild); 13-24 (moderate); 25-36 (moderately severe); and 37-48 (severe withdrawal.
1 week
Mean Peak COWS Score During Treatment Period Prior to VIVITROL Injection
Time Frame: 1 week
The Clinical Opiate Withdrawal Scale (COWS) is a clinician-rated questionnaire designed to measure 11 common opioid withdrawal signs or symptoms. The summed score provides information about the level of physical dependence on opioids. The range of COWS scores is 0-4 (none to minimal); 5-12 (mild); 13-24 (moderate); 25-36 (moderately severe); and 37-48 (severe withdrawal.
1 week
Area Under the Curve (AUC) COWS Score During the Treatment Period Prior to VIVITROL Injection
Time Frame: The COWS was administered 4-6 times per day during the Treatment Period (Days 1-7)
The Clinical Opiate Withdrawal Scale (COWS) is a clinician-rated questionnaire designed to measure 11 common opioid withdrawal signs or symptoms. The summed score provides information about the level of physical dependence on opioids. The range of COWS scores is 0-4 (none to minimal); 5-12 (mild); 13-24 (moderate); 25-36 (moderately severe); and 37-48 (severe withdrawal. To determine the daily AUC COWS score, a curve was generated by plotting the COWS scores against the time the test was taken. The area under this curve was calculated using the linear trapezoidal rule. For the total AUC COWS score, the AUCs calculated for each day during the treatment period were added together. To normalize for time, the total AUC COWS score was then divided by the number of days with daily AUC COWS score during the treatment period. The AUC COWS has a different range than the standard scale as it measures not the score itself, but the area under the curve of the score plotted against time.
The COWS was administered 4-6 times per day during the Treatment Period (Days 1-7)
Mean Score for Desire of Opioids During Treatment Period Prior to VIVITROL Injection
Time Frame: 1 week
The Desire for Opioids Visual Analog Scale (VAS) uses a 100-mm, horizontal linear scale, with 0 anchored on the left representing "no desire for opioids" and 100 anchored on the right representing "strongest imaginable desire for opioids". Subjects placed a vertical line on the scale to indicate their desire for opioids at that particular time.
1 week
Incidence of Adverse Effects
Time Frame: Up to 92 days
The number of subjects who experienced treatment-emergent Adverse Events.
Up to 92 days
Area Under the Curve SOWS Score During the Treatment Period Prior to the VIVITROL Injection
Time Frame: The SOWS was administered 4-6 times per day during the Treatment Period
The Subjective Opiate Withdrawal Scale (SOWS) is a 16-item self-report questionnaire designed to measure the severity of opioid withdrawal symptoms. The subject rates the intensity of symptoms using a 5-point scale. The range of SOWS scores is 1-10 (mild); 11-20 (moderate); and 21-30 (severe). To determine the daily AUC SOWS score, a curve was generated by plotting the SOWS scores against the time the test was taken. The area under this curve was calculated using the linear trapezoidal rule. For the total AUC SOWS score, the AUCs calculated for each day during the treatment period were added together. To normalize for time, the total AUC SOWS score was then divided by the number of days with daily AUC SOWS score during the treatment period. The AUC SOWS has a different range than the standard scale as it measures not the score itself, but the area under the curve of the score plotted against time.
The SOWS was administered 4-6 times per day during the Treatment Period
