Scientific title
Patients with cancer for whom IV paclitaxel (at a dose of 80 mg/m2 IV over 1 hour) is indicated will be treated with intravenous paclitaxel and Oraxol (Paclitaxel + HM30181AK-US) to evaluate bioavailability, safety and tolerability of Oraxol.

Description of intervention(s) / exposure
Crossover Design:

Study treatments will be administered on consecutive weeks with 1 week between each treatment administration.

There are two sequences; IV paclitaxel followed by 15 mg oral HM30181 methanesulfonate monohydrate plus 270 mg oral paclitaxel and,
HM30181 methanesulfonate monohydrate plus 270 mg oral paclitaxel followed by IV paclitaxel.

Treatment details:
80 mg/m2 IV paclitaxel (as Taxol registered trademark or generic) infused over 1 hour (Day 1 or Day 8) plus premedication per standard local practice, or

15 mg oral HM30181 methanesulfonate monohydrate plus 270 mg oral paclitaxel (Days 1 and 2 or Days 8 and 9). HM30181AK-US tablet will be administered 1 hour before oral paclitaxel; no premedication is allowed during this treatment sequence.

Qualified staff will administer IV paclitaxel treatment and monitor the subject for safety. Subjects will remain at the study site for at least the first 24 hours after dosing of IV paclitaxel for PK blood sample collection.

Qualified staff will administer HM30181 methanesulfonate monohydrate plus 270 mg oral paclitaxel. Subjects will remain at the study site for the first 48 hours after dosing of Oraxol for PK blood sample collection.

Subjects may leave the site and return for PK blood sample collections after 24 hours for IV paclitaxel or 48 hours of Oraxol PK blood collections have been completed and will return to the study site for the remaining PK blood collections. If more convenient, at the discretion of the investigator, the subjects may be discharged to a local motel or remain housed at the study site for the entirety of the PK blood collection periods for both IV paclitaxel and Oraxol.

The second week of randomized treatment may be delayed for up to 2 weeks, if needed, to allow the subject to recover to less than or equal to Grade 1 CTCAE toxicity from the prior study treatment.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be screened within 28 days of the first dose of study drug and all safety evaluations, will be performed after the subject provides informed consent and eligibility criteria are met. Eligible subjects are adults with cancer for whom therapy with IV paclitaxel at a dose of 80 mg/m2 is indicated.

Sequence dosing will be explained to subjects at the time of obtaining the informed consent. On Day -1, after all eligibility criteria have been met, the subject will be notified of their assigned sequence. This is an open-label study, unblinded study. The sequence will be generated by the statistician and the Investigator will assign sequences in chronological order. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
This is an open-label study. Subjects will be randomly assigned to a treatment sequence. A simple randomization table created by computer software (i.e. computerized sequence generation) will be used to generate sequence assignment.

Statistical methods / analysis
Methods:
Statistical analyses will be reported using summary tables, graphs, and data listings. Continuous variables will be summarized using the mean, standard deviation, median, minimum, and maximum. Summaries of PK parameters will also include the geometric mean and the coefficient of variation. Categorical variables will be summarized by counts and by percentage of subjects in corresponding categories. All raw data obtained from the case report forms as well as any derived data will be included in data listings.
Analysis:
Pharmacokinetic:
Plasma concentrations for paclitaxel only will be analyzed to determine the following PK parameters: Cmax, AUC0-t, AUC0-inf, Tmax, and t1/2 will be determined for each formulation.
Absolute bioavailability of Oraxol will be determined by comparing the ratio of the dose-adjusted AUC0-inf of Oraxol to that of IV paclitaxel.
Pharmacodynamic: Not applicable.
Pharmacokinetic-Pharmacodynamic: Not applicable.

Summary
Brief summary
Oraxol is a combination of an oral tablet, HM30181
methanesulfonate, and capsules that contain paclitaxel. HM30181 is a drug that helps the body absorb paclitaxel, a drug used to treat cancer. The purpose of this study is to measure the levels of paclitaxel in your blood at different times when given by intravenous (IV) drip (through a vein in the arm) compared to the levels of paclitaxel at different
times in the blood when given by mouth (as Oraxol). This is called pharmacokinetic or “PK” testing
