This randomized phase I trial studies the side effects and the best dose of retinoid 9cUAB30 in healthy volunteers. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of retinoid 9cUAB30 may keep cancer from forming.
PRIMARY OBJECTIVES: I. The primary objective is to determine the toxicities and recommended phase II dose of 9cUAB30. The co- primary objective is to characterize the urine and plasma single dose and steady state pharmacokinetics of 9cUAB30 in normal volunteers. SECONDARY OBJECTIVES: I. To correlate the pharmacokinetics of 9cUAB30 with toxicity. II. To compare observed toxicity between placebo controls and each dose level. III. To assess for any change in single dose PK after repeat dosing (Day 1 vs. Day 36). IV. To assess the following potential biomarkers of UAB30: * Telomerase activity (measurement of telomeric repeats) in PBMCs. * Gene expression of DNA methyltransferase in PBMCs. * Gene expression of CYP2B6 in PBMCs. OUTLINE: This is a dose-escalation study. Participants are randomized to 1 of 2 treatment arms. ARM I: Participants receive retinoid 9cUAB30\* orally (PO) on days 1-28. ARM II: Participants receive placebo\* PO on days 1-28. Courses repeat every 28 days in the absence of unacceptable toxicity. \*NOTE: Participants receive doses on days 8, 15, 22 and 29 after they have fasted for 12 hours. After completion of study treatment, patients are followed up on days 7 and 30.

Recommended phase II dose of 9cUAB30 based on the MTD
Time frame: 28 days
Pharmacokinetics of 9cUAB30 in normal volunteers
Using one-sample t-tests, or Wilcoxon signed-rank tests as appropriate in order to evaluate the single vs. steady state levels. An appropriate regression model will be used to explore the relationship of dose with change in PK.
Time frame: Baseline, days 1, 8, 15, 22, 36, and 43
Correlation between pharmacokinetic and toxicity as assessed by CTCAE
Time frame: Up to 36 days
Comparison of toxicity between placebo and controls as assessed by CTCAE
To compare toxicities at each dose level to placebo, the Chi-square test will be used for the presence or absence of toxicities, and Wilcoxon rank-sum tests will be used for CTCAE grade and investigator defined relationship data.
Time frame: Up to 36 days
