Description

Naloxone: A specific opiate antagonist that has no agonist activity. It is a competitive antagonist at mu, delta, and kappa opioid receptors. [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

naloxone : A synthetic morphinane alkaloid that is morphinone in which the enone double bond has been reduced to a single bond, the hydrogen at position 14 has been replaced by a hydroxy group, and the methyl group attached to the nitrogen has been replaced by an allyl group. A specific opioid antagonist, it is used (commonly as its hydrochloride salt) to reverse the effects of opioids, both following their use of opioids during surgery and in cases of known or suspected opioid overdose.

Effects

Naloxone has a high affinity for the µ-opioid receptor and acts as a competitive antagonist, thus reversing the effects of opioids. The drug has a dose-dependent, significant anorectic effect when administered to normal rats, consistent with an antagonism of central or peripheral enkephalinergic or endorphinergic mechanisms.

Naloxone has been shown to induce LH release in female but not in male rats 10-25 days of age. Nalox one dispensing has substantially increased, in part driven by standing orders. SAIA-NalOXone has strong potential for improving naloxon distribution from syringe service programs.

Treatment

Naloxone pretreatment (82.5 nmol/rat, 30 min before zinc administration) reverted the water intake to the high levels observed in zinc-free dehydrated animals. Treatment induced a marked increase in catecholamine plasma concentrations, metabolism, and cardiovascular stimulation during anesthesia with propofol and methohexital.

Bioavailability

The mean absolute bioavailability of naloxone from the orally administered PR tablets was very low, ranging from 0.5% to 10%. The low oral bioavailability makes the precipitation of the acute opioid withdrawal symptoms unlikely following oral oxycodone/nalox one exposure.

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)

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."

Slope Change From Baseline for Pupil Size

Photographs of subjects' pupils were measured horizontally and vertically, 15 minutes before the first hydromorphone dose and every 15 minutes after each hydromorphone/placebo for hydromorphone dose, for up to 1 hour. Size was the product of vertical and horizontal measures. The slope, determined by linear regression, was used as a summary measure of the dose-response relationship between the hydromorphone dose and pupil size. The steeper the slope, the greater the hydromorphone effect. A slope of zero indicated no evidence of a hydromorphone effect. (NCT01218984)

Change in the Patient Assessment of Constipation Symptoms (PAC-SYM) Total Score

"The Constipation Assessment (PAC-SYM) is a 12-item self-report questionnaire that assessed the severity of symptoms of constipation. Participants were asked How severe have each of these symptoms been in the last two weeks? e.g. Pain in your stomach. There are 3 subscales: 4 questions on abdominal symptoms, 3 on rectal symptoms and 5 on stool symptoms. Responses were rated on a 5-point Likert scale ranging from 0 (absence of symptom) to 4 (very severe symptoms). If the changes in the overall or subscale scores are positive then there is a worsening in symptoms associated with constipation. The change in the assessment of constipation symptoms (PAC-SYM) total score from the Randomization Visit to the Final Evaluation Visit.

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."

Patient Global Impression of Change (PGIC)

"The Patient Global Impression of Change Scale (PGIC) is one question capturing the individual's overall perception of efficacy of treatment in a clinical trial. It uses verbal outcome categories on a 7-point scale with very much worse and very much better as anchors and no change in the middle. The verbal categories were coded on a scale with -3 very much worse,+3 very much better, and 0 same. To calculate the mean and standard deviation of each group (Bup/Opioid Increase) we took the sum of each participants final PGIC score and divided by the total number of participants." (NCT01875848)

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)

Change From Placebo in Reinforcing Effects (Breakpoint) by Study Week and Simulated mu Opioid Receptor Occupancy (μORO)

"This endpoint explores the correlation between the reinforcing effects of hydromorphone and simulated mu opioid receptor occupancy.~Data are reported as change from placebo least square mean of Log10 transformed values for reinforcing effects. Reinforcing Effects tasks began >= 5 hours after hydromorphone challenge. Participants made 12 choices between a preference for working for the amount of hydromorphone dosed that day or for money. The hydromorphone break point value is assigned to the highest level of hydromorphone units earned, with 1 unit having a breakpoint value of 5 and 12 units with a value of 2160.~Change from placebo was calculated as Active Challenge result - Placebo Challenge result.

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. Analyses were carried out on the log10 transformed hydromorphone breakpoint value." (NCT02044094)

Impulsivity (Delayed Discounting)

Impulsivity, measured by the Delayed Discounting cognitive task, based on a series of 30 computer-administered trials or questions. Indifference points (a measure of how much a person values a delayed reward) are determined for time delays of: 1 day, 7 days, 30 days, 180 days, and 365 days, and these are used to calculate an Area Under the Curve which ranges from 0 to 1 (lower numbers indicate higher impulsivity) as a metric of probability. (NCT02805972)
Timeframe: Impulsivity was assessed before the study visit 1 intervention.

The Roland-Morris Disability Questionnaire (RMDQ)

The Roland-Morris Questionnaire (RMDQ) is a self-administered disability measure in which greater levels of disability are reflected by higher numbers on a 24-point scale. The RMDQ has been shown to yield reliable measurements, which are valid for inferring the level of disability, and to be sensitive to change over time for groups of patients with low back pain. Higher scores indicate greater disability. Total RMDQ scores are used before and after each intervention by group. The range of scores is from 0 - 24. (NCT04034004)
Timeframe: The Roland-Morris Disability Questionnaire was administered at the baseline, post-intervention session 6 and session 7. Outcome measurements will compare RMDQ from baseline to session 7.

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.
