覚せい剤使用障害に対するチルゼパチド
肥満とメタンフェタミン使用障害を併発する個人に対するチルゼパチド
This is an open-label pilot study to evaluate the feasibility and preliminary efficacy of using tirzepatide when prescribed for its United States (US) Food and Drug Administration (FDA)-approved weight-related indication in individuals with comorbid methamphetamine use disorder.
調査の概要
詳細な説明
This study will enroll up to 45 individuals with moderate-to-severe methamphetamine use disorder who meet the FDA-approved weight-related indication for tirzepatide [as an adjunct to a reduced-calorie diet and increased physical activity for chronic weight management in adults with an initial body mass index (BMI) of: 1) 30 kg/m2 or greater (obesity) or 2) 27 kg/m2 or greater (overweight) in the presence of at least one weight-related comorbid condition (e.g., hypertension, dyslipidemia, type 2 diabetes mellitus, obstructive sleep apnea or cardiovascular disease)].
Enrolled participants will receive weekly treatment with tirzepatide for a 32-week period that will be followed by 4-week-long observational follow-up. Participants of this study will be seen for weekly visits where they will complete clinical and/or laboratory assessments.

- History of Multiple Endocrine Neoplasia syndrome type 2
- Known serious hypersensitivity (e.g., anaphylaxis, angioedema) to tirzepatide or any of the excipients in tirzepatide
- History of angioedema or anaphylaxis with a GLP-1 receptor agonist
- Current Stage 3 or higher Chronic Kidney Disease, defined as eGFR <60 at Screening
- Current inadequately controlled diabetes, defined as HbA1c > 7.0 at Screening
- History of diabetic retinopathy
- Current pregnancy or lactation
- Treatment with another investigational drug or intervention within the past one month (30 days prior to consent)
- Have any condition for which study participation would not be in their best interest (e.g., cognitive impairment, unstable general medical condition, intoxication, active psychosis) or that could prevent, limit, or confound the protocol-specified assessments, in the opinion of the investigator or their designee.

実験的:Tirzepatide
Eligible participants who are enrolled will receive once-weekly subcutaneous injections of tirzepatide for a 32-week period in accordance with FDA-prescribing label guidelines. |
Eligible participants who are enrolled will receive once-weekly subcutaneous injections of tirzepatide for a 32-week period. Following the instructions of the FDA-approved prescribing label, participants or a licensed study clinician will administer the tirzepatide injection subcutaneously in either the abdomen, thigh, or upper arm once weekly for 32 weeks total. Following the instructions of the FDA-approved prescribing label, the dosing schedule will include a 4-week titration at a starting dosage of 2.5mg/week. After four weeks, dosage will be increased in 2.5mg increments. The recommended maintenance dosages per prescribing label are 5mg/week, 10mg/week, or 15mg/week injected subcutaneously. Maximum dosage (up to 15mg/week) will be optimized for each individual. We will use commercially available tirzepatide, primarily dispensed as ZEPBOUND® for this study, but in the event of medication shortage or other pharmacy-related issue, MOUNJARO® may be dispensed as an alternative.

Effect of tirzepatide on self-reported use of methamphetamine
時間枠:36 weeks
|
Self-reported use of methamphetamine will be assessed through Timeline Followback. The Timeline Followback procedure will be used to elicit the participant's self-reported use of illicit substances, including but not limited to stimulants, and polysubstance use starting at the Screening Visit and continuing throughout study participation. During the Screening Visit, this form will be used to assess illicit use of substances for the 30-day period prior to written consent. During the study, TLFB will be administered to document the participant's self-reported use of illicit substances, nicotine, and tobacco for each visit since the previous TLFB assessment. Participant's drug of choice will be asked and determined by study coordinator and recorded along with the TLFB assessment. |

Changes in self-reported symptoms of anhedonia from baseline to the end of the 32-week treatment phase
時間枠:32 weeks
|
Anhedonia, the inability to experience pleasure, will be assessed by the Snaith-Hamilton Pleasure Scale (SHAPS). The SHAPS questionnaire contains 14 items related to experiencing pleasure over the last several days. Participants are asked to rate their level of agreement or disagreement with each prompt. The scale has a scoring range of 0-14 where a higher point value indicates a higher level of anhedonia. |

Changes in gastrointestinal symptom severity from baseline until the end of the 32-week treatment phase
時間枠:32 weeks
|
Gastrointestinal symptom severity will be assessed by the Gastrointestinal Symptom Rating Scale (GSRS): a disease-specific instrument of 15 items combined into five symptom clusters depicting Reflux, Abdominal pain, Indigestion, Diarrhea and Constipation. The GSRS scale is graded on a seven-point Likert-type scale where a lower score (1) represents less symptom severity and highest score (7) represents greater symptom severity. |
