Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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. Once the dose of Oraxol has been confirmed in the KX-ORAX-002 study, then enrollment of patients who have not participated in the KX-ORAX-002 study can be allowed. 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). Participants in Group B (N=8) will receive the same weekly paclitaxel capsule treatment as the remainder of the subjects except for 1 dosing week (at least 1 week following the paclitaxel capsule PK sampling period) during which they will receive paclitaxel tablets and undergo PK assessments.

Allocation Method

NON_RANDOMIZED

Intervention Model

FACTORIAL

For 1 dosing week (at least 1 week following the paclitaxel capsule PK sampling period, ie, at Week 5 or later), a subgroup of 8 participants (Group B) will receive Oraxol as HM30181 plus a tablet formulation of paclitaxel. For the remainder of the study, Group B participants will receive the current clinical capsule formulation of paclitaxel. This will allow for comparison of the bioavailability of these 2 formulations with minimal impact on safety or activity.

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
