Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This was a multicenter, open, random, balanced, three-period, three-sequence and semi-repetitive cross study with 48 subjects. Eligible subjects were randomly assigned in a 1:1:1 ratio to receive one period of test formulation or two period of reference formulation, followed by a 1-day washout period and administration of the alternate formulation. Serial blood samples for pharmacokinetic assessment were collected at 0 hours (predose) up to 8 hours postdose. The plasma concentrations of capecitabine were analyzed by LC/MS-MS. Pharmacokinetic parameters (non-compartmental model) were assessed with WinNonlin software. The pharmacokinetic parameters assessed were area under the plasma concentration-time curve from time 0 to the time of last measurable concentration (AUC0-t), AUC from time zero to infinity (AUC0-∞), the peak plasma concentration of the drug (C max ), time needed to reach maximum concentration (Tmax), the elimination half-life (t1/2), and terminal elimination rate (λz). All were analyzed using an ANOVA model after logarithmic transformation of the data. For establishing bioequivalence (BE) for capecitabine， reference-scaled average bioequivalence (RSABE) acceptance criteria and average bioequivalence (ABE) acceptance criteria were used. Safety and tolerability was assessed during the entire study period.

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

28 years to 69 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
