Can healthy volunteers participate?

Key exclusion criteria
1. Currently taking a prohibited concomitant medication:

- Strong inhibitors (eg, ketoconazole) or strong inducers (eg, rifampin or St.
John's Wort) of cytochrome P450 (CYP) 3A4 (within 2 weeks prior to the start of
dosing in the study)

- Strong inhibitors (eg, gemfibrozil) or strong inducers (eg, rifampin) of CYP2C8
(within 2 weeks prior to the start of dosing in the study)

- Known P-glycoprotein (P-gp) inhibitors or inducers. Participants who are taking
such medications but who are otherwise eligible may be enrolled if they
discontinue the medication =1 week before dosing and remain off that medication
through the end of PK sampling after the administration of the second study
treatment.

- An oral medication with a narrow therapeutic index known to be a P-gp substrate
(eg, digoxin, dabigatran) within 24 hours prior to start of dosing in the study

2. Use of warfarin. Participants receiving warfarin who are otherwise eligible and who
may be appropriately managed with low molecular weight heparin, in the opinion of the
Investigator, may be enrolled in the study provided they are switched to low molecular
weight heparin at least 7 days prior to receiving study treatment.

3. Unresolved toxicity from prior chemotherapy (participants must have recovered all
significant toxicity to = Grade 1 CTCAE toxicity1 from previous anticancer treatments
or previous investigational agents). This does not extend to symptoms or findings that
are attributable to the underlying disease

4. Received investigational agents within 14 days or 5 half-lives prior to the first
study dosing day, whichever is longer

5. Women of childbearing potential who are pregnant or breastfeeding

6. Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, clinically significant myocardial
infarction within the last 6 months, unstable angina pectoris, clinically significant
cardiac arrhythmia, bleeding disorder, chronic pulmonary disease requiring oxygen, or
psychiatric illness/social situations that would limit compliance with study
requirements

7. Major surgery to the upper GI tract, or have a history of GI disease or other medical
condition that, in the opinion of the Investigator may interfere with oral drug
absorption

8. A known history of allergy to paclitaxel. Participants whose allergy was due to the IV
solvent (such as Cremophor®) and not paclitaxel will be eligible for this study.

9. Any other condition which the Investigator believes would make a subject's
participation in the study not acceptable

Summary
Brief summary
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)
(AUC0-8), 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 AUC0-8 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 (AUC0-8). 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).
