Description

Buprenorphine: A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

buprenorphine : A morphinane alkaloid that is 7,8-dihydromorphine 6-O-methyl ether in which positions 6 and 14 are joined by a -CH2CH2- bridge, one of the hydrogens of the N-methyl group is substituted by cyclopropyl, and a hydrogen at position 7 is substituted by a 2-hydroxy-3,3-dimethylbutan-2-yl group. It is highly effective for the treatment of opioid use disorder and is also increasingly being used in the treatment of chronic pain.

Effects

Buprenorphine-naloxone has a very high affinity for the mu-receptor and can cause precipitated opioid withdrawal, typically more severe than withdrawal that occurs naturally. The transdermal matrix patch renders the substance particularly difficult to extract for illicit purposes.

Buprenorphine/naloxone has been shown to be effective for treating opioid use disorder (OUD) It has been raised as a potential treatment for depression as well as suicidal behavior but may pose certain risks.

Incident Hepatitis B Infections

Serum samples were tested at baseline and between 26-52 weeks later for Hepatitis B surface antigen (HBsAg) using a commercial enzyme immunoassay (EIA) (Abbott Murex HBsAg version 3.0). If the HBsAg test was initially non-reactive, then the participant was considered to be negative for HBsAg. If the HBsAg test was initially reactive, then it was repeated in duplicate. If at least two of 3 tests were reactive, then the participant was considered to be positive for HBsAg. (NCT00270257)

Incident Hepatitis C Infections for Thailand and China

"HCV antibody using two different HCV EIA assays (Ortho HCV antibody version 3.0 and Wantai HCV antibody assay) at baseline and between 26-156 weeks later.~If both HCV EIA antibody assays were nonreactive, then the participant was considered not to be HCV infected. If either assay was reactive, then the Ortho HCV assay was repeated in duplicate. If two of 3 Ortho HCV assays were reactive, then the participant was considered to be HCV infected. Samples that were repeatedly reactive for HCV antibody at a follow-up visit were tested for HCV RNA by the Roche COBAS® AmpliPrep/COBAS® TaqMan® HCV assay. Not all participants had follow-up testing performed in China due to early closure of the study by the Data Safety Monitoring Board on account of futility due to a low HIV incidence (the primary study endpoint).~Analysis was done separately for both countries" (NCT00270257)

The Number of Subjects Who Had Ineffective Treatment or Who Discontinued Due to Reasons Other Than Ineffective Treatment in the Double-blind Phase

"Note: The total numbers of Subjects w/ineffective treatment or who discont'd for placebo and BTDS are 1 less because there were reasons other than lack of efficacy that made up this total: adverse event, death, lost to follow- up, protocol violation, and other. Example for placebo 89+5=94; however, 93 is indicated for the total because there is 1 subject in the placebo group who was counted under ineffective treatment and discontinued due to reasons other than lack of efficacy. The same is true for 1 subject in BTDS." (NCT00312195)

Psychomotor/Cognitive Performance Effects Assessed by Trails B

The Trails B task specifically measures set shifting and executive functioning within the Trail-Making Test. Part B consists of 25 circles distributed over a sheet of paper. Participants are asked to connect the circles in an ascending pattern, alternating between numbers and letters (i.e., 1-A-2-B-3-C, etc.). Results are reported as the number of seconds required to complete the task; therefore, higher scores reveal greater impairment. (NCT00460239)

Changes in HIV Risk

"As measured by the AIDS Risk Inventory. The AIDS Risk Inventory (ARI) is a 166 item structured interview that assesses the number and frequency of drug-related and sexual risk behaviors in the preceding 3 months. Calculation of the ARI total score is based on the frequency of occurrence of a given behavior and on the recency of this behavior, with recency being weighted more than a life-time occurrence of the same behavior. Higher values are associated with greater risk of HIV transmission (worse).~There are 10 subscales comprised of between 8 and 24 items. Subscales scores are based on the sum of the individual items and the overall ARI total score is the sum of the subscales.~Scores can range from 0 to 350, although among opioid dependent patients most values are below 100 with means between 50 and 60 depending on characteristics of the patients and treatment status."

Outcomes represent mean peak withdrawal as rated on the Clinical Opiate Withdrawal Scale (COWS) total score. Withdrawal was collected 7 times daily and daily peak values were identified for each participant and averaged together as a function of group. Primary outcomes were mean peak results from the 7-day taper period and first 7 days post-taper. The COWS is an 11-item observer-rated measure of opioid withdrawal severity. Items are rated on individual Likert scales and the total score range is 0-47. Higher values indicate more severe withdrawal. (NCT01188421)

CYP3A4 Inhibition by Observation of Plasma Nor-buprenorphine Production Assessed by the Erythromycin Breath Test.

As part of subject screening, Erythromycin Breath Tests (EBT) were done on all potential subjects (enrolled population). CYP 3A4 inhibition was calculated by taking the difference of the baseline 14C erythromycin metabolism, subtracting the 14C erythromycin metabolism during ketoconazole treatment, dividing this difference by the baseline 14C erythromycin metabolism, and multiplying by 100 to express results in the form of percent inhibition. CYP3A4 inhibition was only done when subjects were on ketoconazole. (NCT01259115)

Change From Baseline in NRS Pain Intensity

The NRS Pain intensity score is a segmented version of a visual analog scale used to measure pain. The scale is from 0 (no pain) to 10. Scores between greater than 0 and 3 are considered mild pain, scores from greater than 3 to 6 are moderate and greater than 6 to 10 are severe. The daily average is calculated and used to calculate the change from baseline at week 52. (NCT01298765)

Treatment Satisfaction Questionnaire for Medication/Global Satisfaction

Treatment Satisfaction Questionnaire for Medication/Global Satisfaction at Week 28. Patients complete a 14 item questionaire that measures 4 scales based on side effects, effectiveness, convenience and global satisfaction. All items have either five or seven responses (except item 4), scored from one (least satisfied) to five or seven (most satisfied). The 7-item scales have a non-neutral midpoint, such that there are more positive response options than negative response options. Item scores are summed to give four domain scores, which are in turn transformed to a scale of 0-100. Item 4 was not included for scoring. If an item score is missing and half of the items in the domain are complete, domain scores may be imputed from the person-specific mean score of completed items (NCT01298765)

Pain Right Now Assessment by Patients Aged 12 to 16 Years, Inclusive

"Pain right now was assessed using a 100-mm visual analogue scale (VAS). The 100-mm VAS is a 100-mm line with 1 end marked as no pain and the other marked as pain as bad as it could be. The patient was asked to make a mark on that line indicating his or her level of pain. Pain right now score was defined as the distance (in mm) from the no pain end to the patient's mark; 0=no pain and bigger numbers indicate more pain. For screening to week 4, pain right now was assessed 30 minutes before initial BTDS application on day 1; one hour after initial BTDS application on day 1; thereafter, once daily at approximately 8 PM for the first 4 weeks. Baseline was the last assessment prior to the first dose.

Pharmacokinetics (PK) of Buprenorphine Following Transdermal Administration: Apparent Clearance (CL/F)

The population PK (PopPK) of BTDS buprenorphine in pediatric patients ages 7 to 16 years was described by a 2-compartment model with sequential zero- and first-order absorption from the patch. A fixed allometric relationship was used to describe the effects of changes in ideal body weight (IBW) across pediatric patients on all clearance and volume parameters. Given the sparse sample collections, small sample size, and complexity of the absorption process with the patch formulation, this PopPK model was fit to the pediatric data using nonlinear mixed effects modeling (NONMEM) Bayes method with selective use of priors from previous adult PopPK results. Estimates of fixed effects from the final model were used to calculate the CL/F after patch dosing given the covariate distribution in the PopPK dataset and the typical weights from children in the National Health and Nutrition Examination Survey (NHANES) dataset.

Pain Right Now Assessment by Patients Aged 7 to 11 Years, Inclusive

"Pain right now was assessed using the Faces of Pain Scale-Revised (FPS-R). The FPS-R is a horizontal row of 6 faces representing pain intensity, with no hurt at the far left and hurts worst at the far right; the intensities are scored as 0, 2, 4, 6, 8, or 10. A score of 0=no pain, and 10=very much pain. For screening to week 4, pain right now was assessed at 30 minutes before initial BTDS application on day 1; one hour after initial BTDS application on day 1; thereafter, once daily at approximately 8 PM for the first 4 weeks. Baseline score was the last assessment prior to the first dose.

Area Under the Concentration Versus Time Curve (AUC) at Steady State of Methadone Enantiomers When Administered With or Without Boceprevir

AUC is a measure of the amount of drug in the blood over time, measured at steady state (time at which the amount of drug eliminated by the body is in equilibrium with the amount taken in). The Day 1, 0 through 24 hour samples were for methadone levels in the absence of boceprevir co-administration. The Day 7, 0 through 24 hour samples were for methadone levels in the presence of boceprevir co-administration. The Day 5 and 6 predose samples were to check steady state for methadone + boceprevir. (NCT01396005)
Timeframe: Methadone samples collected Day 1, 0 (predose) through 24 hours post-dose (Day 2). Boceprevir and methadone samples collected Day 7, 0 (predose) through 24 hours post-dose (Day 8). Predose samples also collected on Days 5-6.

Participants With Treatment-Emergent Adverse Events (TEAEs)

TEAE=any untoward medical occurrence that develops or worsens in severity after dispensation of the study drug and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= a marked limitation in activity. Relation of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent one of the outcomes listed in this definition. A serious AE (SAE) is defined as any AE occurring at any dose that results in any of the following outcomes: death; lifethreatening AE; hospitalization or prolongation of existing hospitalization; a persistent or significant disability/incapacit (NCT01738503)

Human Immunodeficiency Virus (HIV) Risk Behavior Assessment by Assessing Change in Risk Assessment Battery (RAB) Score

"The RAB is a self-administered, multiple choice questionnaire. It offers a quick and confidential assessment of both needle sharing practices and sexual activity associated with HIV transmission.~The RAB is composed of 45 simple questions which uses discrete response. The questions have different numbers of items, and scores for a single question can range from 0 to 7, with higher values reflecting more instances of risk behavior. The RAB is scored by adding the values that correspond to the responses selected by the subject for the items. This total score is then divided by 40, the highest possible score for the overall instrument, yielding a score from 0 to 1.~HIV risk behaviors will be assessed via score on the Risk Assessment Battery at baseline and month 6--difference between baseline and month 6."

Time to Relapse (Intent to Treat Population)

Relapse occurs if the participant is using any non-protocol prescribed opioids regularly starting at day 21 post-randomization or thereafter. Operationally, relapse is defined as either: (a) four consecutive opioid use weeks, or (b) seven consecutive days of use by self-report. A use week is defined as any week during which a participant self-reports at least one day of use during that week, provides a urine sample positive for non-protocol opioids, or fails to provide a urine sample. Self-report of opioid (heroin or prescription opioids) and other substance use is ascertained at each weekly study visit using the Timeline Follow-Back for each day leading back to the previous visit. Urine is collected at each study visit and tested for opioids. A missed UDS counts as a use week. (NCT02032433)

Predicted mu Opioid Receptor Occupancy (μORO) by Mean Buprenorphine Concentrations and Study Week

"A population pharmacokinetic/pharmacodynamic (PK/PD) model was developed to model the relationship between buprenorphine plasma concentrations and brain μORO based on 2 published clinical trials. This model used individual buprenorphine plasma concentrations measured to derive muORO individual predictions that were further described using summary statistics. The relationship between buprenorphine plasma concentration and μORO was best described by a maximal effect (Emax) model:~µORO = E(max)*Cp / EC(50) + Cp~Where Cp is the plasma concentration of buprenorphine, Emax is the maximal μORO, and EC50 is the plasma concentration of buprenorphine that is expected to achieve 50% of the maximal μORO. A direct (instantaneous) relationship between buprenorphine plasma concentration and µORO, i.e. without equilibration delay, was assumed.~Row title format: Study Week: buprenorphine plasma concentrations for placebo/ 6 mg / 18 mg challenge dosages" (NCT02044094)

Reinforcing Effects Of the Daily Randomized Hydromorphone Challenge as Measured by the Mean Hydromorphone Break Point Value at Weeks 1-12

"The ability of RBP-6000 to reduce the reinforcing effects of hydromorphone used money as a choice alternative to hydromorphone.~Reinforcing Effects Tasks began no earlier than 5 hours after randomised hydromorphone administration for each day. Each test consisted of the participant making 12 choices between a preference for working for the amount of hydromorphone dosed earlier that day or for money (each choice therefore has a scale of 0-12). The hydromorphone break point value is the ratio of the highest number of choices for hydromorphone to the highest number of choices for money. Hydromorphone breakpoint values were then analysed by week using a repeated measures mixed-effects model with period, hydromorphone sequence, and hydromorphone dose as fixed effects and subject nested within hydromorphone sequence as a random effect.

Measures of Withdrawal: Clinical Opiate Withdrawal Scale (COWS)

The secondary outcome measures the change in baseline in the Clinical opiate withdrawal scale (COWS), which is a scale consisting of 11 common opiate withdrawal signs or symptoms, rated on a numeric scale with higher scores associated with greater withdrawal symptoms. A total score was calculated as the sum of the responses to the 11 signs/symptoms for a total range of 0-48. Withdrawal severity was classified, based on the total score, as follows: 0-4=none/normal, 5-12=mild, 13-24=moderate, 25-36=moderately severe, more than 36=severe withdrawal. (NCT02180659)

NRS SPID Over 0 to 8 Hours After Time 0 (NRS SPID-8)

Pain intensity was assessed by the participant using an 11-point NRS from 0=no pain to 10=worst possible pain. Pain intensity scores were collected at Baseline (prior to study drug) and at multiple time points up to 8 hours after Time 0 (administration of first dose of study drug). Pain intensity difference is calculated by subtracting the pain intensity at each time point from the pain intensity at Time 0. The SPID scores are the sum of the differences at each time point multiplied by the duration in hours since the previous time point. Positive numbers indicate a reduction in pain [maximum (max)=10 at each time point] and negative numbers indicate an increase in pain [minimum (min)=-10 at each time point]. The overall min and max are -10 and 10 times the number of hours specified; SPID-8 range is -80 to 80. The NRS SPID-8 was analyzed using an analysis of covariance (ANCOVA) model, which included treatment and site as main effects and Baseline pain intensity as the covariate. (NCT02310581)

Change From Baseline in the Clinical Opiate Withdrawal Scale (COWS) Through Week 24 Analyzed by Mixed Model for Repeated Measures

"COWS is an 11-item instrument used to assess signs and symptoms of opioid withdrawal (Wesson et al., 1999). The score is the sum of the responses for a total range of 0-48. The COWS is commonly used by clinicians treating patients with buprenorphine to monitor the severity of withdrawal. COWS scores below 5 are considered not indicative of withdrawal. Scores from 5 to 12 are considered mild withdrawal; from 13 to 24 moderate withdrawal; 25 to 36 moderately severe withdrawal, and 37-48 severe withdrawal. Negative change from baseline values indicate a lessening of withdrawal symptoms.~Baseline was defined as the last non-missing value prior to subcutaneous injection on Day 1.

Participants With Adverse Events During the Treatment Period

Treatment-emergent adverse event (TEAE) = any untoward medical occurrence that develops or worsens in severity after dispensation of the study drug and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= a marked limitation in activity. Relation of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent one of the outcomes listed in this definition.

Change From Baseline in the Clinical Opiate Withdrawal Scale (COWS) at End of Study (Weeks 25 and 49)

"COWS is an 11-item instrument used to assess signs and symptoms of opioid withdrawal. The score is the sum of the responses for a total range of 0-48. The COWS is commonly used by clinicians treating patients with buprenorphine to monitor the severity of withdrawal. COWS scores below 5 are considered not indicative of withdrawal. Scores from 5 to 12 are considered mild withdrawal; from 13 to 24 moderate withdrawal; 25 to 36 moderately severe withdrawal, and 37-48 severe withdrawal. Negative change from baseline values indicate a lessening of withdrawal symptoms.~Baseline was defined as the last non-missing value prior to subcutaneous injection on Day 1. Baseline value is reported as an observed actual value. Weeks 25 and 49 represent change from baseline values." (NCT02510014)

Total Pain Relief (TOTPAR) Over 4, 8, 24 and 48 Hours After Time 0

TOTPAR was assessed by the participant using a 5-point NRS (0=no relief, 1=a little, 2=some, 3=a lot, 4=complete relief). TOTPAR scores were collected at Baseline (prior to study drug) and at multiple time points up to 48 hours after Time 0 (first dose of study drug). The TOTPAR scores are the sum of the pain relief at each time point multiplied by the duration in hours since the previous time point. Larger positive numbers indicate more pain relief (maximum=4 at each time point) and smaller positive numbers indicate less pain relief (minimum=0 at each time point). The overall minimum is 0 for each variable and the overall maximum is 4 times the number of hours specified for the variable: TOTPAR-4=(0 to 16), TOTPAR-8=(0 to 32), TOTPAR-24=(0 to 96) and TOTPAR-48=(0 to 192). TOTPAR-4, TOTPAR-8, TOTPAR-24 and TOTPAR-48 were analyzed using an ANCOVA model with factors for treatment, site and baseline pain intensity. (NCT02634788)

NRS SPID Over 4 Hours (SPID-4), 8 Hours (SPID-8) and 24 Hours (SPID-24) After Time 0

Pain intensity was assessed by the participant using an 11-point NRS from 0=no pain to 10=worst possible pain. Pain intensity scores were collected at Baseline (prior to study drug) and at multiple time points up to 48 hours after Time 0 (administration of first dose of study drug). Pain intensity difference is calculated by subtracting the pain intensity at each time point from the pain intensity at Time 0. The SPID scores are the sum of the differences at each time point multiplied by the duration in hours since the previous time point. Positive numbers indicate a reduction in pain [max=10 at each time point] and negative numbers indicate an increase in pain [min=-10 at each time point]. The overall min and max are -10 and 10 times the number of hours specified: SPID-4=(-40 to 40), SPID-8=(-80 to 80) and SPID-24=(-240 to 240). The NRS SPID-4, 8 and 24 were analyzed using an ANCOVA model which included treatment and site as main effects and Baseline pain intensity as the covariate. (NCT02634788)

Time to Onset of Analgesia

Time to onset of analgesia was measured as time to first perceptible pain relief confirmed by meaningful pain relief using the 2-stopwatch method. The study staff started 2 stopwatches as soon as the first dose of study drug was administered. Each participant was instructed to stop the first stopwatch when he or she experienced any perceptible pain relief and the second stopwatch when he or she experienced pain relief that was meaningful to them. If the second stopwatch was not stopped, time was censored at the time of the second dose of study drug or the use of rescue medication, whichever came first. If both stopwatches were not stopped time was censored at the time of the second dose of study drug or the use of rescue medication whichever came first. Time to onset of analgesia was defined as the time when the first stopwatch was stopped given that the second stopwatch is stopped. (NCT02634788)

Numeric Rating Scale (NRS) Summed Pain Intensity Difference (SPID) Over 0 to 48 Hours After Time 0 (NRS SPID-48)

Pain intensity was assessed by the participant using an 11-point NRS from 0=no pain to 10=worst possible pain. Pain intensity scores were collected at Baseline (prior to study drug) and at multiple time points up to 48 hours after Time 0 (administration of first dose of study drug). Pain intensity difference is calculated by subtracting the pain intensity at each time point from the pain intensity at Time 0. The SPID scores are the sum of the differences at each time point multiplied by the duration in hours since the previous time point. Positive numbers indicate a reduction in pain [maximum(max)=10 at each time point], and negative numbers indicate an increase in pain [minimum(min)=-10 at each time point]. The overall min and max are -10 and 10 times the number of hours specified; SPID-48 range is -480 to 480. The NRS SPID-48 was analyzed using an analysis of covariance (ANCOVA) model, which included treatment and site as main effects and Baseline pain intensity as the covariate. (NCT02634788)

"Subjective Effects as Assessed by Score on Feel Drug, Feel High, Like Drug, and Want More Subscales of the Drug Effects Questionnaire Subjective Response With and Without Buprenorphine"

"The Drug Effects Questionnaire (DEQ) is a visual analog scale questionnaire that assesses the extent to which subjects experience four subjective states: Feel Drug, Feel High, and Want More. The Feel Drug, Feel High, Like Drug, and Want More subscales are reported. All subscales are scored on a visual analogue scale (scroll bar on computer screen) ranging from 0 -100. 100 represents the highest score for that subjective state, and the higher the score, the worse the outcome."

Changes in Resting State Disorganization Between Baseline and One Week by Person by Lapsed Category

"The measure of resting state organization is a z-value derived from Pearson's r-values. They represent the effect of the association between the brain activity of the seed region and each brain voxel over time during the resting state FMRI scan. A central z-value of 0 means that there is no association between the seed region and the voxel.~Positive and negative z-values approaching 0 reflect increasingly weaker associations, and more extreme positive and negative values reflect stronger associations. Attributing the qualitative labels better or worse to these values depend upon the brain network and context. In many networks (eg, task-positive cognitive control network), a stronger positive correlation is thought to reflect better network organization. In the task-negative default mode network a stronger positive relationship is considered by some as worse. For this study, these are not yet used as clinical measures and there are not known cutoffs." (NCT02696096)

Area Under the Curve (AUC) for COWS Scores During the Treatment Period and VIVITROL Induction and Post-VIVITROL Observation Period

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). The daily AUC COWS score is derived based on the actual time (unit in minutes) COWS administered on each day by using the linear trapezoidal rule, and then divided by the COWS administration duration (last COWS administration time minus first COWS administration time) for that day. The normalized AUC COWS score is the summation of daily AUC COWS score during the relevant period divided by the number of days with daily AUC COWS score. (NCT02696434)

Summary of Change From Baseline in EuroQoL Group EQ-5D-5L Scores Over Time-Open Label Phase

Change from Open Label Titration baseline in EuroQol Group 5-dimension 5-level self-report questionnaire score in the Open Label Phase. The EuroQoL Group 5-Dimension 5-Level Self-Report Questionnaire (EQ-5D-5L) descriptive system is a generic, multidimensional, health-related, quality-of-life instrument. The profile allows subjects to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and mood, using a 5-level scale. These combinations of attributes were converted into a weighted health-state index score, according to the US population-based algorithm, with higher scores indicating better quality of life. The score ranges from 0-100 with 0 as the worst health and 100 as the best health. (NCT02946073)

The EuroQoL Group 5-Dimension 5-Level Self-Report Questionnaire (EQ-5D-5L) descriptive system is a generic, multidimensional, health-related, quality-of-life instrument. The profile allows subjects to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and mood, using a 5-level scale. These combinations of attributes were converted into a weighted health-state index score, according to the US population-based algorithm, with higher scores indicating better quality of life. The score ranges from 0-100 with 0 as the worst health and 100 as the best health. (NCT02946073)

Composite Outcome Measure for a Reduction in Both Alcohol Use Disorder (AUD) and Post-Traumatic Stress Disorder (PTSD) Symptoms

AUD is measured by the Timeline Follow Back (TLFB). This instrument documents the amount of daily alcohol consumption (in grams) and categorizes the World Health Organization Risk Levels of Alcohol Use. The are 4 different WHO Risk Levels: Very High Risk, High Risk, Medium Risk, and Low Risk (including abstinence). An AUD reduction is defined as a WHO risk reduction of at least one category from baseline to week 8. PTSD symptom is measured by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5). This 30-item interview assesses PTSD diagnosis and symptom severity. The CAPS-5 Total Symptom Severity Score (TSSS) ranges from 0 to 80, with higher scores indicating worse symptoms. A reduction in PTSD symptom is defined as a 10+ point decrease in the TSSS from baseline to week 8. A positive response for the composite primary outcome measure is defined as at least a 1-category risk reduction on the WHO s and at least a 10-point decrease in TSSS from baseline to Week 8.

Total Score on COWS At Timepoints During the Treatment Period

Clinical Opiate Withdrawal Scale (COWS) is an 11-item instrument used to assess signs and symptoms of opioid withdrawal. The score is the sum of the responses for a total range of 0-48. The COWS is commonly used by clinicians treating patients with buprenorphine to monitor the severity of withdrawal. COWS scores below 5 are considered not indicative of withdrawal. Scores from 5 to 12 are considered mild withdrawal; from 13 to 24 moderate withdrawal; 25 to 36 moderately severe withdrawal, and 37-48 severe withdrawal. (NCT03993392)

Number of Participants With Adverse Events (AEs)

An AE is defined as any untoward medical occurrence in a participant administered an Investigational Product (IP) and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding; abnormal laboratory test result or other safety assessment, symptom, or disease temporally associated with the use of IP whether or not considered related to the IP. A treatment-emergent adverse event (TEAE) was defined as an AE with onset at any time from first dosing until last scheduled procedure. AEs were considered serious (SAEs) if the AE resulted in death, was life-threatening, resulted in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, resulted in congenital anomaly, or birth defect or required inpatient hospitalization or led to prolongation of hospitalization.

Baseline observation was last non-missing observation prior to first dose. (NCT04447287)
Timeframe: 'buprenorphine/naloxone': Baseline and 1 hour postdose Day 11; 'ASP8062 in combination with buprenorphine/naloxone' and 'Placebo ASP8062 in combination with buprenorphine/naloxone': Baseline and 1 hour postdose Day 12

InterventionPercentage of oxygen saturation (Mean)
Buprenorphine/Naloxone (Run-in Period)0.1
ASP8062 in Combination With Buprenorphine/Naloxone (Investigational Period)-0.6
Placebo ASP8062 in Combination With Buprenorphine/Naloxone (Investigational Period)-0.7

Change From Baseline in Blood Oxygen Saturation (SpO2) at 2 Hour Postdose

The blood oxygen saturation (SpO2) was measured using a pulse oximeter placed on the participant's fingertip. Change from baseline in SpO2 was calculated as Day 11 minus Baseline for arm 'buprenorphine/naloxone', and Day 12 minus Baseline for arms 'ASP8062 in combination with buprenorphine/naloxone' and 'Placebo ASP8062 in combination with buprenorphine/naloxone'. Baseline observation was last non-missing observation prior to first dose. (NCT04447287)
Timeframe: 'buprenorphine/naloxone': Baseline and 2 hour postdose Day 11; 'ASP8062 in combination with buprenorphine/naloxone' and 'Placebo ASP8062 in combination with buprenorphine/naloxone': Baseline and 2 hour postdose Day 12

InterventionPercentage of oxygen saturation (Mean)
Buprenorphine/Naloxone (Run-in Period)0.2
ASP8062 in Combination With Buprenorphine/Naloxone (Investigational Period)-0.8
Placebo ASP8062 in Combination With Buprenorphine/Naloxone (Investigational Period)0.3
