Bowman-Birk Inhibitor Concentrate in Preventing Cancer in Healthy Men

Phase I Single Dose Safety and Pharmacokinetic Study 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 preventing cancer in healthy men. Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of Bowman-Birk inhibitor concentrate may prevent cancer.

Study Overview

• Status: Completed
• Conditions: Unspecified Adult Solid Tumor, Protocol Specific
• Intervention / Treatment: Other: placebo; Drug: Bowman-Birk inhibitor concentrate

Detailed Description

PRIMARY OBJECTIVES:

I. Determine the toxic effects of Bowman-Birk inhibitor concentrate, administered as an orange juice suspension, in healthy male participants.

II. Determine a safe dose range of this drug in these participants. III. Determine a recommended phase II dose of this drug in these participants.

SECONDARY OBJECTIVES:

I. Determine the pharmacokinetics of this drug in these participants.

OUTLINE: This is a randomized, placebo-controlled, double-blind, dose-escalation study.

Participants are sequentially assigned to 1 of 4 dose level cohorts. One participant in each dose level cohort is randomized to receive placebo. Participants receive 1 of 4 escalating doses of oral Bowman-Birk inhibitor concentrate or placebo, as an orange juice suspension, on day 1.

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

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Arm I (Bowman-Birk inhibitor concentrate); Participants are sequentially assigned to 1 of 4 dose level cohorts. One participant in each dose level cohort is randomized to receive placebo. Participants receive 1 of 4 escalating doses of oral Bowman-Birk inhibitor concentrate or placebo, as an orange juice suspension, on day 1.	Drug: Bowman-Birk inhibitor concentrate; Given orally; Other Names: BBIC
Placebo Comparator: Arm II (placebo); Participants are sequentially assigned to 1 of 4 dose level cohorts. One participant in each dose level cohort is randomized to receive placebo. Participants receive 1 of 4 escalating doses of oral Bowman-Birk inhibitor concentrate or placebo, as an orange juice suspension, on day 1.	Other: placebo; Given orally; Other Names: PLCB

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Safety as measured by NCI Common Toxicity Criteria and a recommended Phase II dose (RPTD)	Up to 4 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pharmacokinetics measurements of BBI in the blood and urine	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.	0 (immediately prior to BBIC administration), 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24, and 48 hours after BBIC administration
