Background: Triple-negative breast cancer (TNBC) comprises a heterogeneous group of diseases which are generally associated with poor prognosis. Recently, the PARP inhibitor olaparib was approved as first targeted treatment beyond antiVEGF therapy for the BRCA1/2 mutated subgroup of TNBC. However, cytotoxic agents still remain the mainstay of treatment for this breast cancer subtype. Ixazomib is a selective and reversible inhibitor of the proteasome, which has been mainly investigated as treatment of multiple myeloma. In a preclinical cell line model for TNBC the first-generation proteasome inhibitor bortezomib showed synergistic efficacy with cisplatin. Clinical data are available for carboplatin plus bortezomib in metastatic ovarian and lung cancers showing remarkable antitumor activity (47% and 38% response rate, respectively) and good tolerability. In solid tumors cytotoxic effect of proteasome inhibitors is thought to be mediated through different mechanisms: (1) Inhibition of the Fanconi Anemia and BRCA1 DNA repair mechanism (2) Inhibition of p53 degradation (3) Inhibition of NF-kappa B signaling cascade. Based on this evidence, the phase I/II MBC-10 trial will evaluate the toxicity profile and efficacy of the oral second-generation proteasome inhibitor ixazomib in combination with carboplatin in patients with advanced TNBC. Trial Design: Patients with metastatic TNBC pretreated with at least one prior line of chemotherapy for advanced disease with a confirmed disease progression and measurable disease are eligible for this study.Patients will receive ixazomib in combination with carboplatin on days 1, 8, and 15 in a 28-day cycle. The phase I part of this study uses an alternate dose escalation accelerated titration design. After establishing the maximum tolerated dose (MTD), accrual continues to evaluate the efficacy and safety of the combination (phase II, including 41 evaluable patients). All patients will continue on study drugs until disease progression, unacceptable toxicity or discontinuation for any other reason. Primary endpoint of the phase II is overall response rate, secondary endpoints include safety profile, progression-free survival and quality of life. The MBC-10 trial is accompanied by a broad biomarker program investigating predictive biomarkers for treatment response and potential resistance mechanisms to the investigational drug combination. This trial is open for patient enrollment since November 2016 in six Austrian cancer centers. Accrual is planned to be completed within two years.

背景:三阴性乳腺癌(TNBC)包括一组异质性疾病,通常与预后不良有关。最近,PARP抑制剂奥拉帕尼被批准为BRCA1/2突变TNBC亚组的第一个靶向治疗,而不是抗vegf治疗。然而,细胞毒性药物仍然是治疗这种乳腺癌亚型的主要方法。Ixazomib是一种选择性和可逆的蛋白酶体抑制剂,主要用于多发性骨髓瘤的治疗。在TNBC的临床前细胞系模型中,第一代蛋白酶体抑制剂硼替佐米与顺铂显示出协同效应。卡铂联合硼替佐米治疗转移性卵巢癌和肺癌的临床数据显示出显著的抗肿瘤活性(分别为47%和38%的缓解率)和良好的耐受性。在实体肿瘤中,蛋白酶体抑制剂的细胞毒作用被认为是通过不同的机制介导的:(1)抑制Fanconi贫血和BRCA1 DNA修复机制(2)抑制p53降解(3)抑制NF-kappa B信号级联。基于这一证据,I/II期MBC-10试验将评估口服第二代蛋白酶体抑制剂ixazomib联合卡铂治疗晚期TNBC患者的毒性和疗效。试验设计:转移性TNBC患者接受至少一种既往化疗治疗的晚期疾病,确认疾病进展和可测量的疾病符合本研究的条件。患者将在28天周期的第1、8和15天接受伊沙唑米联合卡铂治疗。本研究的I期部分采用交替剂量递增加速滴定设计。在确定最大耐受剂量(MTD)后,accrual继续评估联合治疗的有效性和安全性(II期,包括41名可评估的患者)。所有患者将继续使用研究药物,直到疾病进展、不可接受的毒性或因任何其他原因停药。II期的主要终点是总缓解率,次要终点包括安全性、无进展生存期和生活质量。MBC-10试验伴随着一个广泛的生物标志物项目,研究治疗反应的预测性生物标志物和对研究药物组合的潜在耐药机制。该试验自2016年11月起在六个奥地利癌症中心开放患者登记。项目计划在两年内完成。引用格式:Rinnerthaler G, Gampenrieder SP, Petzer A, Burgstaller S, Voskova D, Rossmann D, Balic M, Egle D, Rumpold H, Singer CF, Petru E, Melchardt T, Ulmer H, mlinitsch B, Greil R.
