Evaluation of Co-Administration of Betahistine as Adjunctive to Olanzapine in Healthy Subjects

December 29, 2010 updated by: OBEcure Ltd.

Evaluation of Safety, Drug-Drug Interactions and Pharmacokinetic Profiles of Co-Administration of Escalating Doses of Extended Release and Standard Formulations of Betahistine as Monotherapy and as Adjunctive to Olanzapine in Healthy Subjects

The study aims to evaluate the safety and pharmacokinetics of extended release and standard formulations of betahistine when administered as monotherapy and as compared to their safety and pharmacokinetics when co-administered with olanzapine and to determine potential dose limiting toxicities and/or drug-drug interactions affecting the pharmacokinetics or safety of either medication, with particular emphasis on somnolence and weight gain secondary to olanzapine treatment

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 41 years (Adult)

Accepts Healthy Volunteers
