简要总结
Nonrandomized, open label, single arm, Simon's two stage MinMax design trial of neoadjuvant weekly carboplatin plus paclitaxel, followed by doxorubicin and cyclophosphamide in patients with operable Triple Negative Breast Cancer (TNBC)
详细描述
This is a single arm, Phase 2, open label, Simon's two stage MinMax design trial to evaluate the safety and efficacy of weekly carboplatin in combination with standard neoadjuvant chemotherapy in subjects with previously untreated triple negative breast cancers who are candidates for potentially curative surgery.
Subjects will receive carboplatin (Area Under the Curve (AUC) 2 mg/mL/min) + paclitaxel (80 mg/m2) Carboplantin plus Paclitaxel (CbP) followed by doxorubicin and cyclophosphamide (AC). All subjects will receive CbP on Day 1 of 12 weekly cycles (Visits CbP1 - CbP12) via infusion during Chemotherapy Segment 1 as indicated in the Study Schema. Dose interruptions and dose modifications are allowed based upon tolerability and may extend Chemotherapy Segment 1 duration to a maximum of 16 weeks. Beginning with Chemotherapy Segment 2 all subjects will receive doxorubicin (60 mg/m2) and cyclophosphamide (600 mg/m2) on Day 1 of four 14-day cycles (Visits AC1 - AC4). For subjects who experience toxicities due to carboplatin, paclitaxel, doxorubicin or cyclophosphamide, the appropriate dose modifications or dosing delays should be managed according to Section 11.2. Dose modifications may result in the total duration of therapy being greater than the planned 24 weeks. The objective of this study is to determine efficacy and tolerability of low dose, weekly carboplatin in combination with weekly paclitaxel followed by standard doxorubicin/cyclophosphamide as neoadjuvant therapy for triple-negative breast cancer.

- •NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
- •Women of childbearing potential (WOCP) must not be pregnant or breast-feeding. A negative serum or urine pregnancy test is required within 14 days of study registration. If the urine test cannot be confirmed as negative, a serum pregnancy test will be required.
- •Women of childbearing potential (WOCP) must be willing to use two effective methods of birth control such as an oral, implantable, injectable, or transdermal hormonal contraceptive, an intrauterine device (IUD), use of a double barrier method (condoms, sponge, diaphragm, or vaginal ring with spermicidal jellies or cream), or total abstinence for the course of the study until 90 days after the last dose of study drug.
- •NOTE: Women are considered to be of childbearing potential unless they are postmenopausal (≥45 years of age and has not had menses for greater than 12 consecutive months or bilateral oophorectomy) or surgically sterile (bilateral tubal ligation or hysterectomy) or not heterosexually active for the duration of the study and at least 60 days after the last dose of study drug.

排除标准

- •Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study).
