Advanced Breast Cancer
Brief summary
This trial will treat patients with advanced breast cancer with a new anti-cancer medicine used in combination with two existing anti-cancer medications: Albumin-bound paclitaxel (ABI-007), Carboplatin and Herceptin. Participants will be given the combination therapy on a weekly basis and may continue on therapy as long as their condition improves and drug toxicity is tolerated.
Interventions
Administered by intravenous infusion.
Carboplatin dose was calculated using a modified Calvert formula (creatinine clearance was substituted for GFR): Total dose (mg) = (target AUC) x (creatinine clearance + 25). Note: AUC = 6 was initially targeted, but could be decreased due to toxicity.
Administered by IV infusion

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Who Achieved an Objective Confirmed Complete or Partial Overall Response | Objective response was evaluated every 2 cycles, up to a maximum of 39 cycles (approximately 39 months) | Percentage of participants who achieved an objective confirmed complete or partial overall response based on Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0. A complete response (CR) is the disappearance of all known disease and no new sites or disease related symptoms confirmed at least 4 weeks after initial documentation. A partial response (PR) is at least a 30% decrease in the sum of the longest diameters of target lesions, taking as a reference the baseline sum of the longest diameters confirmed at least 4 weeks after initial documentation. PR is also recorded when all measurable disease has completely disappeared, but a non-measurable component (i.e., ascites) is still present but not progressing, or with the persistence of one or more non-target lesions and/or the maintenance of tumor marker level above the normal limits. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With a Total Response | Evaluated every 2 cycles, up to a maximum of 39 cycles. | Total response was defined as the percentage of participants with stable disease (SD) for ≥ 16 weeks or complete or partial overall response. Stable disease was defined as neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease. Progressive disease is at least a 20% increase in the sum of the longest diameters of target lesions, taking as reference the smallest sum of the longest diameters recorded since the treatment started; or the appearance of one or more new lesions; or the unequivocal progression of a non-target lesion. |
| Time to Disease Progression | Assessed every 2 cycles, up to a maximum of 39 cycles. | Time to disease progression was measured from the date of first dose of study drug to the start of disease progression. Patients who did not have disease progression at the end of follow-up were censored at the last known time that the patient was evaluated for progression. Progression is at least a 20% increase in the sum of the longest diameters of target lesions, taking as reference the smallest sum of the longest diameters recorded since the treatment started; or the appearance of one or more new lesions; or the unequivocal progression of a non-target lesion. Time to disease progression was summarized using Kaplan-Meier methods. |
| Duration of Response | Assessed every 2 cycles, up to a maximum of 39 cycles. | Duration of response was evaluated by measuring progression-free survival for participants with a complete response or partial response. Progression-free survival was defined as the time from the first dose of study drug to the start of progression or patient death (whichever occurred first). Participants who did not have progression or were still alive were censored at the last known time the patient was progression free. Patients that initiated other anticancer therapy prior to progression were censored at the time when new anticancer therapy was initiated. Progression is at least a 20% increase in the sum of the longest diameters of target lesions, taking as reference the smallest sum of the longest diameters recorded since the treatment started; or the appearance of one or more new lesions; or the unequivocal progression of a non-target lesion. |
| Overall Patient Survival | From Day 1 until approximately 44 months. | Overall survival was defined as the time from the day of randomization to patient death (due to any cause), as assessed by post study follow-up on a monthly basis for 3 months and every 3 months. Participants still alive were censored at the last known time that the patient was alive. Patient survival was estimated using Kaplan-Meier methods. |
| Number of Participants With Adverse Events (AEs) | Day 1 up to 39 cycles | A Treatment-emergent AE was any AE that began or worsened after the start of study drug through 30 days after the last dose of study drug or end of study whichever is later. A treatment related toxicity was one considered by the investigator to be possibly, probably or definitely related to study drug. AEs were graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events v3.0 (CTCAE) on the following scale: Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life-threatening, Grade 5 = death. A serious adverse event (SAE) is any untoward medical occurrence at any dose that: is fatal or life-threatening; results in persistent or significant disability or incapacity; requires or prolongs in-patient hospitalization; is a congenital anomaly/birth defect in the offspring of a patient; and conditions not included in the above that may jeopardize the patient or may require intervention to prevent one of the outcomes listed above |

Recruitment details
Due to slow patient accrual, only 32 patients of the planned 50 patients were enrolled. Patients were enrolled between June 2004 and July 2007.
Participants by arm
| Arm | Count |
|---|---|
| Albumin-bound Paclitaxel, Carboplatin + Herceptin Participants received albumin-bound paclitaxel, 100 mg/m\^2 weekly every 3 out of 4 weeks, carboplatin at an area under the curve (AUC) = 6 every 4 weeks and Herceptin weekly, 4 mg/kg the first week and 2 mg/kg on all subsequent weeks by intravenous (IV) infusion for up to 6 cycles in the absence of disease progression or intolerable toxicity. Participants could continue treatment with chemotherapy beyond 6 cycles at the discretion of the investigator, but Herceptin therapy was to continue to be administered weekly (2 mg/kg) until intercurrent illness, disease progression, unacceptable toxicity, patient withdrawal or administration of any non-protocol anti-cancer treatment. | 32 |

A partial response (PR) is at least a 30% decrease in the sum of the longest diameters of target lesions, taking as a reference the baseline sum of the longest diameters confirmed at least 4 weeks after initial documentation. PR is also recorded when all measurable disease has completely disappeared, but a non-measurable component (i.e., ascites) is still present but not progressing, or with the persistence of one or more non-target lesions and/or the maintenance of tumor marker level above the normal limits.
