Study to Evaluate AD04 in Adults With Alcohol Use Disorder (AUD) and Selected Serotonin Transporter Polymorphisms
Bu çalışma, belirli serotonin taşıyıcı gen polimorfizmleri taşıyan ve alkol kullanım bozukluğu (alcohol use disorder) olan yetişkinlerde AD04 (ondansetron) adlı ilacı plasebo ile karşılaştırarak incelemektedir. Orta-şiddetli alkol kullanım bozukluğu tanısı olan, genetik testte uygun genotipleri bulunan ve alkol tüketimini azaltmak isteyen 18 yaş ve üzeri bireyler katılabilmiştir. Çalışma Faz 3 aşamasında yürütülmüş ve tamamlanmıştır.

2. an average alcohol consumption at the medium risk level (defined by the WHO "International guide for monitoring alcohol consumption and related harm" as \>40 grams of ethanol/day for males and \>20 grams of ethanol/day for females) for the 4 weeks prior to the Screening Visit,
3. ≤14 consecutive abstinent days in the 4 weeks preceding the Screening Visit.
7. Willingness to provide a blood sample for DNA analysis at the Screening visit. The blood sample collected for DNA testing contains at least one of the following genotypes as measured by Adial's validated method:
* rs4795541-LL genotype of the insertion-deletion polymorphism (5'-HTTLPR) in the 5'-regulatory region and rs1042173-TT SNP in the 3'-untranslated region of SLC6A4 gene that encodes the serotonin transporter
* rs1150226-AG SNP in HTR3A, the gene that encodes subtype A of the serotonin-3 receptor
* rs1176713-GG SNP in HTR3A, the gene that encodes subtype A of the serotonin-3 receptor
* rs17614942-AC in HTR3B, the gene that encodes subtype B of the serotonin-3 receptor
8. Expressed a wish to reduce or stop alcohol consumption.
9. Willingness to participate in behavioral and medicinal treatments for AUD.
10. Has had a stable residence in the 28 days prior to the Baseline Visit in the study and has no plans to move in the next 9 months. A stable residence is a domicile in which an individual can operate as if it were his or her own homestead and does not include shelters or halfway houses.
11. Provides contact information for 2 individuals who can be used to contact the subject.
12. Able to read and understand, and complete the rating scales and questionnaires accurately, follow instructions, and make use of the behavioral treatments.
13. The subject, if female must:
* have a negative urine pregnancy test prior to the initiation of treatment and agree not to try to become pregnant during the study
* use two adequate methods of contraception \[intrauterine device, oral contraceptives, progesterone implanted rods, or regular medroxyprogesterone acetate injections in addition to condom or diaphragm, or double barrier method (condom or diaphragm + spermicide)\], or
* be post-menopausal having had the last natural menstruation at least 24 months prior to the Screening Visit, or
* have had a hysterectomy or been surgically sterilized prior to baseline.
Exclusion Criteria:
1. Patients with withdrawal symptoms requiring additional medication for withdrawal. If present at Screening/Baseline Visit, subjects must complete a medically supervised detoxification program prior to being able to enroll in the study.
2. Subjects with diagnosis of any of the following concomitant psychiatric disorders: non-treated, unstable schizophrenia, bipolar disorder, other psychotic disorder during the lifetime of the subject. Recent (within last 12 months) diagnosis of a major depressive disorder, post traumatic stress disorder, panic disorder or eating disorders. Subjects with nicotine use disorder, phobic or other anxiety disorders (other than post-traumatic stress disorder or panic disorder) can be included.
3. The subject reports current or recent (within 8 weeks prior to Baseline Visit) treatment with antipsychotics or antidepressants medications, which can have an effect on serotonin receptor or transporter actions.
4. The subject has been treated with any investigational medicinal product within 30 days or 5 half-lives (whichever is longer) prior to the Baseline Visit.
5. The subject is currently participating or has recently (4 weeks prior to the Baseline Visit) participated in a treatment program for alcohol use disorders.
6. Any subject who has suicidal thoughts as evaluated by the Columbia Suicide Severity Rating Scale (C-SSRS) (i.e., has any suicidal ideation of type 4 or 5 on the C-SSRS in the last month).
7. The subject has a clinically significant untreated and unstable illness, for example, hepatic or renal insufficiency, or a cardiovascular, pulmonary, gastrointestinal, endocrine, neurological, infectious, neoplastic, or metabolic disturbance.
8. The subject has clinically significant abnormal vital signs.
9. The subject has a clinically abnormal ECG at the Screening/Baseline Visit, clinically significant cardiovascular disease requiring regular or intensive clinical monitoring, a current history of arrhythmias, or a current or past history of clinically significant QT prolongation, including:
* QTcF \> 450 ms (one ECG at screening and average of 3 12-lead measurements at baseline)
* serum potassium, magnesium or calcium levels outside the central laboratory's reference range
* receiving medications (within the last 7 days prior to the Baseline Visit) that have the potential of prolonging the QT interval or may require such medications during the course of the study
