Analysis of phase I pharmacokinetic studies with targeted molecules based on gender and age

2521 Background: Pharmacokinetic parameters are usually not sufficiently correlated with patient characteristics, such as age, gender, or excretory organ function, and with outcome measures. Female sex has been shown to be a risk factor for clinically relevant adverse drug reactions and acting as a predictive/prognostic factor. Methods: We analyzed Phase I/II oncology trials of solid tumors with targeted agents enrolling Male and Female population (age>18yrs), reporting pharmacokinetic analysis, published between 2000 and 2007. We excluded trials involving Radiation therapy alone, Hematological malignancies, and trials of Gender related pathology (ovarian, prostate and breast cancer). Standard descriptive statistics was used. Results: 160 phase I and II trials involving 48 targeted agents has been selected. 44%, 37% and 19% of the population enrolled for PK analysis is respectively male, female or unknown gender. 65% of the trials have male preponderance. Authors did not specified number of male and femal...
