Bowman-Birk Inhibitor Concentrate in Healthy Men

December 28, 2016 updated by: National Cancer Institute (NCI)

Phase I Single Dose Safety and Pharmacokinetic Study of a New Formulation of Bowman Birk Inhibitor Concentrate, Delivered as an Orange Juice Suspension to Healthy Male Volunteers Between 18 and 65 Years of Age

This randomized phase I trial is studying the side effects and best dose of Bowman-Birk inhibitor concentrate in healthy men. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of Bowman-Birk inhibitor concentrate may prevent cancer.

Detailed Description

OBJECTIVES:

I. Assess the toxicity of single-dose Bowman-Birk Inhibitor Concentrate (BBIC) when administered as a suspension in orange juice in healthy male participants.

II. Determine the appropriate dose range and doses to be used in a subsequent phase I multiple-dose BBIC study that will be based upon the data gathered from this phase I single-dose study.

III. Characterize the pharmacokinetics of single-dose BBIC.

OUTLINE: This is a dose-escalation study of Bowman-Birk Inhibitor Concentrate (BBIC). Participants are sequentially assigned to 1 of 4 dose level cohorts. One participant in each dose level cohort is randomized to receive placebo or BBIC.

Participants receive a single dose of oral BBIC or placebo, as an orange juice suspension, immediately followed by consumption of a defined low-fat breakfast. Participants continue to consume a low-fat diet for the next 48 hours and then resume their normal diet.

Participants undergo blood and urine sample collection periodically for pharmacokinetic studies. Samples are analyzed by a sandwich enzyme-linked immunosorbent assay to measure concentrations of BBIC and its metabolites in serum and urine.

After completion of study treatment, participants are followed once weekly for 4 weeks.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Recommended phase II dose, defined as the highest dose level at which none of the subjects in that dose group experience DLT as measured by NCI Common Toxicity Criteria
Time Frame: Up to 48 hours
Up to 48 hours
Pharmacokinetics of BBIC in the serum as measured by a sandwich enzyme-linked immunosorbent assay
Time Frame: Immediately before BBIC administration and 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, and 48 after administration
Presented in a form of time course of serum BBI concentration after BBIC ingestion by the study subjects and peak concentration (Cmax), time to reach peak concentration (Tmax), area under the curve (AUC), and elimination rate constant (kel) and serum half-lives (t1/2) will be calculated for each subject. Mean, median, and 95% confidence interval will then be calculated for each parameter for each dose group. The relationship between dose and the above parameters will be investigated using simple linear regression.
Immediately before BBIC administration and 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, and 48 after administration
