主要终点:Maximum tolerated dose of vorinostat and azacitidine, defined as the dose at which less than one-third of patients experience a dose limiting toxicity (i.e., fewer than 2 of 6 patients) · Graded according to the National Cancer Institute/Division of Cancer Treatment Common Toxicity Criteria. · Day 28;Precision of the estimated dose-response curve based on induction of lytically replicated viral particles in the plasma following treatment · A non-parametric and a parametric approach will be used. The non-parametric approach will entail averaging the biologic effects from the patients at each time point, plotting them versus dose, and connecting the points to get the dose-response curve. The parametric approach will use a polynomial regression model with two degrees of freedom for modeling dose. A spline model may also be used. · Up to 16 weeks
次要终点:Pharmacokinetics of vorinostat in patients with locally recurrent and metastatic nasopharyngeal carcinoma and NK-T cell nasal lymphoma;Proportions of patients with high and low histone acetylation;EBV promoter demethylation as measured in tumor patients with locally recurrent and metastatic nasopharyngeal carcinoma and NK-T cell nasal lymphoma
患者于第1–10天皮下注射阿扎胞苷,并于第1–14天每日口服伏立诺他两次。每个疗程28天;若无疾病进展或不可接受毒性,重复治疗共4个疗程。
这项 I 期研究评估伏立诺他联合阿扎胞苷治疗鼻咽癌或鼻型结外 NK/T 细胞淋巴瘤的副作用和最佳剂量。研究对象为肿瘤在原发部位附近复发或已转移的患者。伏立诺他和阿扎胞苷属于作用机制不同的化疗药物,可通过杀伤癌细胞、抑制其分裂或扩散来控制肿瘤;二者也可能通过阻断癌细胞生长所需的某些酶发挥作用。联合用药可能杀伤更多癌细胞。
This phase I trial studies the side effects and best dose of vorinostat when given together with azacitidine in treating patients with nasopharyngeal cancer or nasal natural killer T-cell lymphoma that has recurred (come back) at or near the same place as the original (primary) tumor, usually after a period of time during which the cancer could not be detected or has spread to other parts of the body. Drugs used in chemotherapy, such as vorinostat and azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Vorinostat and azacitidine also may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving vorinostat together with azacitidine may kill more cancer cells.
