Reinfection and Risk Behaviors After Treatment of Hepatitis C Virus Infection in Persons Receiving Opioid Agonist Therapy : A Cohort Study.

Background: Hepatitis C virus (HCV) reinfection after successful treatment may reduce the benefits of cure among people who inject drugs.

Objective: To evaluate the rate of HCV reinfection for 3 years after successful treatment among people receiving opioid agonist therapy (OAT).

Design: A 3-year, long-term, extension study of persons enrolled in the CO-STAR (Hepatitis C Patients on Opioid Substitution Therapy Antiviral Response) study (ClinicalTrials.

Health-related quality of life in people receiving opioid agonist treatment and treatment for hepatitis C virus infection.

Background: In people with chronic hepatitis C virus (HCV) infection, viral eradication is associated with improved health-related quality of life (HRQOL).

Objective: To assess changes in HRQOL among participants receiving opioid agonist therapy undergoing treatment for HCV infection.

Methods: COSTAR (NCT02251990) was a randomized, double-blind, placebo-controlled study.

Elbasvir-Grazoprevir to Treat Hepatitis C Virus Infection in Persons Receiving Opioid Agonist Therapy: A Randomized Trial.

Background: Hepatitis C virus (HCV) infection is common in persons who inject drugs (PWID).

Objective: To evaluate elbasvir-grazoprevir in treating HCV infection in PWID.

Design: Randomized, placebo-controlled, double-blind trial.

A Thorough QTc Study Confirms Early Pharmacokinetics/QTc Modeling: A Supratherapeutic Dose of Omarigliptin, a Once-Weekly DPP-4 Inhibitor, Does Not Prolong the QTc Interval.

Omarigliptin is a dipeptidyl peptidase-4 inhibitor being developed as a once-weekly treatment for type 2 diabetes. This double-blind, double-dummy, randomized, 3-period balanced crossover study definitively evaluated the effects of a supratherapeutic omarigliptin dose on QTc interval. Population-specific correction of QT interval (QTcP) was used for the primary analysis.

Effects of Age, Sex, and Obesity on the Single-Dose Pharmacokinetics of Omarigliptin in Healthy Subjects.

Omarigliptin is being developed as a potent, once-weekly, oral dipeptidyl peptidase-4 inhibitor for the treatment of type 2 diabetes. This double-blind, randomized, placebo-controlled study evaluated the effects of age, sex, and obesity on the pharmacokinetics of omarigliptin in healthy subjects. A single oral dose of omarigliptin 10 mg (n = 6/panel) or placebo (n = 2/panel) was administered in the fasted state to elderly nonobese men and women, young obese (30 ≤ body mass index [BMI] ≤ 35 kg/m(2) ) men and women, and young nonobese women of nonchildbearing potential.

Pharmacokinetic and Pharmacodynamic Effects of Multiple-dose Administration of Omarigliptin, a Once-weekly Dipeptidyl Peptidase-4 Inhibitor, in Obese Participants With and Without Type 2 Diabetes Mellitus.

Purpose: Omarigliptin (MK-3102) is a potent, oral, long-acting dipeptidyl peptidase (DPP)-4 inhibitor approved in Japan and in global development as a once-weekly treatment for type 2 diabetes mellitus (T2DM). The aim of this study was to investigate the pharmacokinetic (PK) and pharmacodynamic (PD) effects of omarigliptin in obese participants with and without T2DM.

Methods: This was a Phase I, randomized, double-blind, placebo-controlled, multiple-dose study of 50-mg omarigliptin administered once weekly for 4 weeks.

A pharmacokinetic comparison of adult and paediatric formulations of raltegravir in healthy adults.

Background: Raltegravir is an HIV-1 integrase inhibitor approved for use in adults, children and infants ≥4 weeks of age. As alternatives to the original film-coated tablet, a chewable ethylcellulose (EC) tablet and oral granules for suspension (GFS) have been developed for use in children. The purpose of this study was to evaluate these formulations in adults prior to use in paediatric studies.

Effect of intensive lifestyle intervention on sexual dysfunction in women with type 2 diabetes: results from an ancillary Look AHEAD study.

Objective: Sexual dysfunction is a prevalent problem in obese women with type 2 diabetes. This study examined the effects of intensive lifestyle intervention (ILI) in these women.

Research Design And Methods: Look AHEAD is a 16-center, randomized, controlled trial evaluating the health effects of ILI compared with a control group (diabetes support and education [DSE]).

Lack of an effect of anacetrapib on the pharmacokinetics of digoxin in healthy subjects.

Anacetrapib is currently being developed for the oral treatment of dyslipidemia. A clinical study was conducted in healthy subjects to assess the potential for an interaction with orally administered digoxin. Anacetrapib was generally well tolerated when co-administered with digoxin in the healthy subjects in this study.

Metabolism and excretion of anacetrapib, a novel inhibitor of the cholesteryl ester transfer protein, in humans.

Anacetrapib is a novel cholesteryl ester transfer protein inhibitor being developed for the treatment of primary hypercholesterolemia and mixed dyslipidemia. The absorption, distribution, metabolism, and excretion of anacetrapib were investigated in an open-label study in which six healthy male subjects received a single oral dose of 150 mg and 165 microCi of [(14)C]anacetrapib. Plasma, urine, and fecal samples were collected at predetermined times for up to 14 days postdose and were analyzed for total radioactivity, the parent compound, and metabolites.

The acyclic CB1R inverse agonist taranabant mediates weight loss by increasing energy expenditure and decreasing caloric intake.

Cannabinoid 1 receptor (CB1R) inverse agonists are emerging as a potential obesity therapy. However, the physiological mechanisms by which these agents modulate human energy balance are incompletely elucidated. Here, we describe a comprehensive clinical research study of taranabant, a structurally novel acyclic CB1R inverse agonist.
