A Study to Determine the Bioequivalence of Oraxol in Cancer Patients Treated With Intravenous Paclitaxel
A Randomized Crossover Study to Determine the Bioequivalence of Three Consecutive Daily Doses of Oraxol in Cancer Patients Treated With Intravenous Paclitaxel
This is a multicenter, open-label, 2-stage study with a 2-treatment period crossover design. Eligible participants are adults with cancer for whom weekly therapy with IV paclitaxel at a dose of 80 mg/m2 over 1 hour is indicated.
Stage 1 will consist of an initial cohort (Cohort 1) up to 6 evaluable participants who will receive a dosing regimen of Oraxol consisting of a 15-mg oral HM30181AK-US tablet plus an oral paclitaxel dose of 205 mg/m2, both administered once daily for 3 consecutive days. The stages and cohorts are further described in the "Study Design - Stages and Cohorts" table below. An interim analysis of pharmacokinetic (PK) data from Cohort 1 will be conducted to determine if the administered regimen would appear likely to achieve bioequivalence(BE) (AUC0-∞), if tested in a greater number of participants in Stage 2. If it appears unlikely that the selected regimen will meet the criteria for BE based on AUC0-∞ data, a second cohort (Cohort 2) of up to 6 evaluable participants may be enrolled in Stage 1, and the dose of paclitaxel in Oraxol may be adjusted by a maximum of +/- 25%. If Cohort 2 is enrolled, a second interim analysis will be conducted.
After the interim analysis/analyses (depending on the outcomes), a decision will be made by consensus of the Data Safety and Monitoring Board(DSMB), Kinex, Zenith Technology, and the Principal Investigator as to what dose should be administered in Stage 2. The DSMB will consist of a clinical oncologist, an ethicist, an independent statistician, and additional members, as deemed necessary. A DSMB charter will describe the planned evaluations and decision points used to determine the dose for Stage 2. An additional 18 to 42 evaluable participants will be enrolled into Stage 2 based on the Stage 1 results (AUC0-∞). Thus a total of up to 54 evaluable participants could potentially be enrolled in this study (6 each from Stage 1, Cohorts 1 and 2, and up to 42 participants in Stage 2).

Safety and Tolerability of Oraxol Compared With IV Paclitaxel
Time Frame: From screening until final visit (within 28 days after the last dose of study drug was taken, and preferably before the participant receives any additional chemotherapy)
|
Safety was assessed by recording all adverse events (AEs) and serious adverse events (SAEs), including CTCAE grades (version 4.03); recording concomitant medications; clinical laboratory testing (including hematology, biochemistry, and urinalysis); measurement of vital signs (pulse rate, systolic and diastolic blood pressures, respiratory rate, and body temperature), weight, and body surface area (BSA); performance of electrocardiograms (ECGs); assessment of ECOG performance status; and performance of physical examinations
