Last Updated: 2025-03-12

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 28 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-05-09

Brief Summary

This is a multicenter, open-label, single-arm PK study in patients for whom paclitaxel treatment is indicated.

Detailed Description

This is a multicenter, open-label, single-arm PK study in approximately 24 breast cancer patients for whom paclitaxel treatment is indicated. The study contains 3 periods: the Screening / Baseline Period, the Treatment Period, and the Follow-up Period. A Final Visit will occur within 7 days of the last dose of study treatment. If subjects achieve stable disease (SD), partial response (PR), or complete response (CR) at the end of the Treatment Period, they may continue Oraxol treatment in a separate extension study.

Eligibility Criteria

Inclusion Criteria

1. Signed written informed consent

2. Women ≥18 years of age on day of consent

3. Breast cancer in patients for whom treatment with IV paclitaxel at 80 mg/m2 as monotherapy has been recommended by their oncologist

4. Measurable disease as per RECIST v1.1 criteria

5. Adequate hematological status as demonstrated by not requiring transfusion support or granulocyte-colony stimulating factor (G-CSF) maintain:

• Absolute neutrophil count (ANC) ≥1.5 x 10^9/L
• Platelet count ≥100 x 10^9/L
• Hemoglobin (Hgb) ≥9 g/dL

6. Adequate liver function

• Total bilirubin of ≤1.5 mg/dL
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3 x upper limit of normal (ULN) or ≤5 x ULN if liver metastasis is present
• Alkaline phosphatase (ALP) ≤3 x ULN or ≤5 x ULN if bone metastasis is present
• Gamma glutamyl transferase (GGT) <10 x ULN

7. Adequate renal function as demonstrated by serum creatinine ≤1.5 x ULN

8. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

9. Life expectancy of at least 3 months

10. Willing to fast for 6 hours before and 2 hours after Oraxol administration on all treatment days

11. Willing to abstain from alcohol consumption for 3 days before the first dose of study drug through the completion of the second inpatient PK sampling period

12. Willing to refrain from caffeine consumption for 12 hours before each inpatient dosing period through the completion of protocol-specified PK sampling for that week

13. Subjects must be postmenopausal (>12 months without menses) or surgically sterile (ie, by hysterectomy and/or bilateral oophorectomy) or must be using effective contraception (ie, oral contraceptives, intrauterine device, double barrier method of condom and spermicide) and agree to continue use of contraception for 30 days after their last dose of assigned study treatment.

14. Subjects who are of childbearing potential must have a negative serum pregnancy test at Screening and within 96 hours before dosing.

Exclusion Criteria

1. Have not recovered to ≤ Grade 1 toxicity from previous anticancer treatments or previous investigational products (IPs)

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. Subjects unable to swallow study medication in its intact form or have clinically significant malabsorption syndrome

4. Only site of metastatic disease is unmeasurable according to RECIST v1.1 criteria

5. Known CNS metastasis, including leptomeningeal involvement

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

7. Are currently receiving other medications intended for the treatment of their malignancy

8. Women who are pregnant or breastfeeding

9. Taking prohibited medications:

10. Use of warfarin. Subjects 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.

11. 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

12. Known allergic reaction or intolerance to study medication components

13. Known allergic reaction or intolerance to contrast media

14. Subjects who, in the Investigator's opinion, are not suitable for participation in this study

• Minimum Eligible Age: 18 Years
• Eligible Sex: FEMALE
• Accepts Healthy Volunteers: No
