Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Can healthy volunteers participate?
No
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)
* Strong P-gp inhibitors (eg, verapamil) or strong inducers (eg, rifampin). 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 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 toxicity 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
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. Initially this study is intended as an extension study of KX-ORAX-002 pharmacokinetic study for patients who wish to continue Oraxol treatment and who are eligible to participate. The purpose of this study is to check the safety and tolerability of Oraxol when it is administered on a weekly basis and to confirm the sustained oral bioavailability of paclitaxel following multiple dosing; also compare the relative bioavailability of paclitaxel tablets vs paclitaxel capsules (Group B only).
