Drug: IV paclitaxel |
- Tumor response as determined by response criteria [ Time Frame: 19 to 22 weeks ]Tumor response is evaluated using the response evaluation criteria in solid tumors (RECIST v1.1 criteria).
- Safety and tolerability assessments of Oraxol compared with IV paclitaxel, as determined by laboratory, adverse event (AE) and serious adverse event (SAE) information [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, up to ~48 months (expected end of study).] ]Safety assessments will consist of determining and recording all AEs and SAEs; laboratory evaluation of hematology, blood chemistry, and urine analyses; periodic measurement of vital signs and electrocardiograms (ECGs); and the performance of physical examinations, as detailed in the schedule of procedures and assessments of the protocol
- Progression-free survival (PFS) [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, up to ~48 months (expected end of study). ]The endpoint of progression-free survival is defined as not having died or progression of disease. Lost to follow-up will be considered as censored.
- Overall survival (OS) [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, up to ~48 months (expected end of study). ]The endpoint of overall survival is defined as death, confirmed alive, and lost to follow-up. Alive and lost to follow-up will be considered as censored.

- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- Life expectancy of at least 6 months, in the judgement of the investigator
- Subjects must be postmenopausal (≥12 months without menses) or surgically sterile (ie, by hysterectomy and/or bilateral oophorectomy) or must be using effective contraception and agree to used of contraception for 30 days after their last dose of assigned study treatment.
- Subjects who are of childbearing potential must have a negative screening serum pregnancy test.
Exclusion Criteria:
- Have not recovered to ≤ Grade 1 toxicity from previous anticancer treatments or previous investigational products
- If previously treated with a taxane (paclitaxel or docetaxel) as part of anthracycline-based adjuvant chemotherapy or for metastatic disease, the subject relapsed less than 1 year following treatment
- Only evidence of metastatic disease is to bone or other nontarget or nonmeasurable lesions (including, for example, ascites or plural effusion) according to RECIST v1.1 criteria
- Central nervous system metastasis, including leptomeningeal involvement
- Received IPs within 14 days or 5 half-lives of the first study dosing day, whichever is longer
- Are currently receiving other medications intended for the treatment of their malignancy
- Received radiation therapy within 2 weeks prior to signing informed consent and those for whom radiation therapy is planned within 6 months from the time of signing informed consent
- Women who are pregnant or breastfeeding
- Taking a medication known to be a strong P-gp inhibitor or inducer within 14 days of starting treatment
- Taking an oral medication with a narrow therapeutic index known to be a P-gp substrate within 24 hours prior to start of treatment
- Taking a medication known to be a strong cytochrome P450 (CYP) 3A4 inhibitor (eg, ketoconazole) or inducer (eg, rifampin or St. John's Wort) within 14 days of starting treatment
- Taking a medication known to be a strong inhibitor (eg, gemfibrozil) or inducer (eg, rifampin) of CYP2C8 within 14 days of starting treatment
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, myocardial infarction within the last 6 months, unstable angina pectoris, cardiac arrhythmia, chronic pulmonary disease requiring oxygen, known bleeding disorders, or any concomitant illness or social situation that would limit compliance with study requirements
- 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
- History of significant hypersensitivity-type reactions to paclitaxel or Cremophor EL (polyoxyl 35 castor oil, NF) that would contraindicate the use of IV paclitaxel formulated with Cremophor EL
- Known allergic reaction or intolerance to contrast media
- Documented history of true systemic allergic reaction to 3 or more medications
- For whom the Investigator believes that participation in this study would not be acceptable
- Known chronic hepatitis or cirrhosis
