Pixantrone Dimaleate in Treating Patients With HER2-Negative Metastatic Breast Cancer

• Status: Completed
• Trial end date: 2014-11-15
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as pixantrone dimaleate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving pixantrone dimaleate in different ways may kill more tumor cells.

PURPOSE: This randomized phase II trial is studying how well pixantrone dimaleate works in treating patients with HER2-negative metastatic breast cancer.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Alliance for Clinical Trials in Oncology
• Collaborator: National Cancer Institute (NCI)
• Treatments: Pixantrone

Criteria

Registration and Randomization - Inclusion Criteria

7. The following laboratory values obtained ≤15 days prior to registration.

7.1 Hemoglobin ≥10.0g/dL

7.2 ANC ≥1500/mm^3

7.3 Platelet count ≥100,000/mL

7.4 Total bilirubin ≤1.5 x ULN)

7.5 SGOT (AST) and SGPT (ALT) ≤5 x ULN

7.6 Serum creatinine ≤1.5 x ULN

9. ECOG Performance Status (PS) of 0, 1 or 2.

10. Life expectancy >3 months

11. Ability to complete questionnaire(s) by themselves or with assistance.

12. Patient has provided written informed consent

13. Willingness to return to NCCTG enrolling institution for follow-up.

Registration and Randomization - Exclusion Criteria

1. Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown.

1.1 Pregnant women

1.2 Nursing women

1.3 Men or women of childbearing potential who are unwilling to employ adequate contraception (as determined by the treating physician)

2. Stage III or IV invasive cancer (other than breast cancer) in ≤3 years prior to registration (with the exception of non-melanoma skin cancer).

3. HER2 positive breast cancer (3+ by IHC or FISH amplified) breast cancer by ASCO/CAP guidelines

4. Has already received lifetime cumulative treatment with doxorubicin equivalent to >400 mg/m2.

5. >3 prior chemotherapy regimens for breast cancer.

5.1 NOTE: This number includes (neo)adjuvant chemotherapy, if given. If (neo)adjuvant chemotherapy HAS been given it counts as one (1) regimen.

6. Major surgery, chemotherapy, or immunologic therapy ≤3 weeks prior to registration.

6.1 NOTE: If patient has received prior treatment with bevacizumab, treatment on this trial should not begin until ≥4 weeks after the last dose of bevacizumab.

7. Radiotherapy ≤4 weeks prior to registration, except if to a non-target lesion only.

7.1 Prior radiation to a target lesion is permitted only if there has been clear progression of the lesion since radiation was completed.

7.2 If patient receives single dose radiation for palliation or radiation to non-target lesion, they may immediately proceed to registration without waiting.

7.3 Acute adverse events from radiation must have resolved to ≤Grade 1 (according to current version of NCI CTCAE).

8. Evidence of active brain metastasis including leptomeningeal involvement.

8.1 CNS metastasis controlled by prior surgery and/or radiotherapy is allowed. To be considered controlled, there must be at least 2 months of no symptoms or evidence of progression prior to study entry and corticosteroid therapy given to control brain edema must have been discontinued.

9. Uncontrolled hypertension (blood pressure [BP] >160/90mmHg on ≥2 occasions at least 5 minutes apart). (Patients who have recently started or adjusted anti-hypertensive medications are eligible providing that BP is <140/90mmHg on any new regimen for ≥3 different observations in ≥14 days.).

10. Clinically significant cardiovascular or cerebrovascular disease, including any history of the following at any time prior to registration:

10.1 Myocardial infarction

10.2 Unstable angina pectoris

10.3 New York Heart Association (NYHA) Class II or greater congestive heart failure

10.4. Uncontrolled or clinically significant cardiac arrhythmia (patients with controlled atrial fibrillation are eligible)

11. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection or psychiatric illness/social situations that would limit compliance with study requirements.

12. Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens.

13. History of allergy or hypersensitivity to drug product excipients or agents chemically similar to pixantrone.

14. Currently receiving treatment in a different clinical study in which investigational procedures are performed or investigational therapies are administered.

14.1 Patient may not enroll in such clinical trials while participating in this study.

Exception may be granted for trials related to symptom management (Cancer Control) which do not employ hormonal treatments or treatments that may block the path of the targeted agents used in this trial.
