Exploring the PK of Different Doses of Naltrexone in Patients With AUD

Exploring the Pharmacokinetic Characteristics of Different Doses of Naltrexone Implants in Patients With Alcohol Use Disorders

Study Design This study is related to a multicenter, randomized, double-blind, placebo-controlled phase II clinical study to evaluate the efficacy and safety of different doses of naltrexone implants in the treatment of patients with alcohol use disorders (protocol No.: SK2007-NQT-201, hereinafter referred to as II). This study plans to include 60 patients who are interested in participating in this study in Phase II patients, collect PK blood samples from patients, and conduct PK characteristic analysis. The collected plasma samples will be temporarily stored in a -80 ℃ refrigerator and tested after unblinding in Phase II.

Detailed Description

Research Design

This study is related to "a multicenter, randomized, double-blind, placebo-controlled phase II clinical study to evaluate the efficacy and safety of different doses of naltrexone implants in the treatment of patients with alcohol use disorders" (protocol No.: SK2007-NQT-201, hereinafter referred to as II). This study plans to include 60 patients who are interested in participating in this study in Phase II patients, collect PK blood samples from patients, and conduct PK characteristic analysis. The collected plasma samples will be temporarily stored in a -80 ℃ refrigerator and tested after unblinding in Phase II.

Research process and PK blood collection

Twelve blood samples were collected from each patient, about 4mL of venous blood were collected 0 h before administration (within 4h before administration) and 4h, 12h, D1 (24h), D7, D14, D28, D56, D84, D112, D140, D168 days after administration.

At the planned blood collection point, collect approximately 4mL of blood sample into a labeled heparin sodium anticoagulant vacuum collection vessel. After collecting each tube of blood, gently invert it back and forth immediately and pay attention to hemolysis to fully mix the blood with anticoagulants to ensure anticoagulant effect. After sample collection and before centrifugation, the blood sample needs to be placed upright in an ice water bath and transported to the sample pretreatment room. Within 1 hour, the blood sample should be placed in a low-temperature centrifuge for centrifugation.

• Accepts Healthy Volunteers: No

Description

Selection criteria:

1. Volunteer to participate in clinical research; Fully understand and be informed of this experiment and sign informed consent; Willing to follow and capable of completing all testing procedures;
2. The age at the time of signing the informed consent form is ≥ 18 years old;
3. Patients diagnosed as moderate to severe alcohol use disorders based on the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) (four or more items that meet the diagnostic criteria);
4. Have completed withdrawal treatment and have no obvious alcohol withdrawal symptoms for at least one week (≥ 7 days) before randomization/administration [Clinical Institute Alcohol Dependence Withdrawal Assessment Form (CIWA-Ar) score<7 points];
5. Able to provide TLFB alcohol consumption information 2 weeks prior to withdrawal and/or screening;
6. During the 4-week period before withdrawal and/or screening, drink heavily at least twice a week;

Qualified subjects of childbearing age (male and female) must agree to take effective contraceptive measures (hormone or barrier therapy or abstinence) with their partners during the trial period.

Exclusion criteria:

Participants who meet any of the following criteria cannot be selected for the experiment:

1. The researcher determines that participating in this experiment does not comply with the rights and interests of the subjects, or any other circumstances that do not allow the subjects to conduct the study safely;
2. Pregnant and reproductive age women with positive pregnancy tests or lactating women, including those who planned to conceive during the study period. Note: Here, women of childbearing age refer to women with fertility. The following criteria must be met, regardless of their sexual orientation or whether they have undergone tubal ligation: 1) have not undergone hysterectomy or bilateral ovariectomy; Or 2) Have not experienced natural menopause for more than 12 consecutive months (i.e., have menstruated at any time during the previous 12 consecutive months);
3. Significant abnormalities in liver function (such as AST or ALT exceeding twice the upper limit of normal values) or liver failure (including but not limited to: abdominal fluid accumulation, prolonged prothrombin time, international standard ratio (INR) ≥ 1.7, esophageal varicose disease) or liver and gallbladder ultrasound display results have a significant impact on the judgment of the efficacy and safety of the study drug;
4. Suffering from uncontrollable active infectious diseases in clinical practice, such as active hepatitis B (positive for hepatitis B surface antigen (HBsAg) detection and hepatitis B virus (HBV) deoxyribonucleic acid (DNA) copy number>1000 IU/ml), active hepatitis C (positive for hepatitis C virus antibody and hepatitis C virus (HCV) ribonucleic acid (RNA)), etc;
5. A history of congenital hemorrhagic disease (such as hemophilia) or any clinically significant bleeding, or abnormal platelet function, or prothrombin time (PT) exceeding the upper limit of normal values by more than 3 seconds (sec) during coagulation function testing, or platelet count<50 × 109/L；
6. Previous history of severe pancreatitis or severe tremor delirium episodes;
7. According to the judgment of the researchers, the subjects have any severe/uncontrollable systemic diseases (such as respiratory, circulatory, digestive, nervous, hematological, urogenital, endocrine system diseases) or mental illnesses (such as severe depression, schizophrenia, bipolar disorder, etc.) or other major diseases that the researchers believe will hinder the provision of informed consent and make participation in the study unsafe Complicating the interpretation of research outcome data or otherwise affecting the achievement of research objectives;
