The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
National Cancer Institute (NCI)
  Purpose
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.

Condition Intervention Phase
Unspecified Adult Solid Tumor, Protocol Specific Other: placebo Drug: Bowman-Birk inhibitor concentrate Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Official Title: 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

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Safety as measured by NCI Common Toxicity Criteria and a recommended Phase II dose (RPTD) [ Time Frame: Up to 4 weeks ]

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


Estimated Enrollment: 20
Study Start Date: January 2006
Primary Completion Date: April 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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 Name: 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 Name: PLCB

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.
