Clinical Trial Summary

To determine the safety and tolerability of Oraxol as compared to IV paclitaxel in metastatic breast cancer

Description:

This is a Phase 3, open-label, randomized, multicenter study in approximately 360 adult female subjects with histologically- or cytologically-confirmed breast cancer that is metastatic for whom treatment with IV paclitaxel monotherapy has been recommended by their oncologist. Approximately 400 subjects will be enrolled to provide 360 evaluable subjects. The subjects must have measurable metastatic target lesion disease as per RECIST v1.1 criteria. Subjects will be randomized in a 2:1 ratio to either Oraxol or IV paclitaxel (as Taxol or generic).

Exclusion Criteria:

1. Have not recovered to = Grade 1 toxicity from previous anticancer treatments or previous investigational products

2. 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

3. 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

4. Central nervous system metastasis, including leptomeningeal involvement

5. Received IPs within 14 days or 5 half-lives of the first study dosing day, whichever is longer

7. 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

8. Women who are pregnant or breastfeeding

9. Taking a medication known to be a strong P-gp inhibitor or inducer within 14 days of starting treatment

10. Taking an oral medication with a narrow therapeutic index known to be a P-gp substrate within 24 hours prior to start of treatment

11. 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

12. Taking a medication known to be a strong inhibitor (eg, gemfibrozil) or inducer (eg, rifampin) of CYP2C8 within 14 days of starting treatment

13. 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

14. 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

15. 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

16. Known allergic reaction or intolerance to contrast media

17. Documented history of true systemic allergic reaction to 3 or more medications

18. For whom the Investigator believes that participation in this study would not be acceptable

19. Known chronic hepatitis or cirrhosis

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Tumor response as determined by response criteria	Tumor response is evaluated using the response evaluation criteria in solid tumors (RECIST v1.1 criteria).	19 to 22 weeks
Primary	Safety and tolerability assessments of Oraxol compared with IV paclitaxel, as determined by laboratory, adverse event (AE) and serious adverse event (SAE) information	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	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).]
Secondary	Progression-free survival (PFS)	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.	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).
Secondary	Overall survival (OS)	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.	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).
