简要总结
This Phase II trial is being developed following the completion of a Phase I study of the combination of temsirolimus and sorafenib in 25 first-line therapy patients with advanced hepatocellular carcinoma (December 2009 through April 2012). The maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of the combination of temsirolimus is 10 mg IV weekly plus sorafenib 200 mg (oral, twice daily).
详细描述
The hypothesis of this single-arm phase II study is that the combination of temsirolimus and sorafenib will achieve a clinically-meaningful median time to progression (TTP) of at least 6 months, with null hypothesis of less than or equal to 3 months, in first-line systemic therapy for patients with advanced Hepatocellular carcinoma (HCC). A randomized trial would be required to formally compare the efficacy of this combination to sorafenib alone and will be indicated if this phase II study achieves a median TTP of at least 6 months. An interim safety analysis will employ stopping rules after 30% of planned patients have been treated with at least one dose of protocol therapy to ensure the combination does not confer excessive toxicity.
A key aspect of this study will be the requirement of histologic confirmation along with adequate archival tissue for correlative tissue analyses to explore new biomarkers of response to mammalian target of rapamycin (mTOR) inhibition. Circulating biomarker data including enumeration of circulating tumor cells (CTC) and measurement of the tumor marker Alpha-fetoprotein (AFP) will be performed at specific time points to evaluate for predictive value. Specimen banking of tissue, serum, and peripheral blood mononuclear cells will be undertaken to enable future novel biomarker studies. Modified RECIST will be performed in addition to standard RECIST 1.1 to explore for improved imaging predictors of response.

结局指标
主要结局
Median Time to Progression (TTP)
时间窗: 24 months
Median TTP will be calculated in months from date of first dose of protocol therapy to date of removal from study for progression, where progression is defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 as at least a 20% increase in the sum of the longest diameter of the target lesions (SLD), taking as reference the smallest sum of the SLD recorded since the treatment started and minimum 5 millimeter (mm) increase over the nadir, or the appearance of one or more new lesions for target lesions and/or appearance of one or more new lesions and/or unequivocal progression of existing non-target lesions . Kaplan-Meier methods will be used to summarize the primary endpoint
