简要总结
This phase 1 study was developed to identify recommended phase 2 doses (RP2Ds) of AR-42 and pazopanib when given in combination for subsequent clinical trials and may have potentially identified candidate pharmacodynamic and predictive biomarkers.
详细描述
This study was a single-arm, open-label, dose escalation phase 1 trial to determine the RP2Ds of AR-42 and pazopanib when given in combination to patients with advanced Renal Cell Carcinoma (RCC) or Soft Tissue Sarcoma (STS). Eligible patients had recurrent, unresectable, or metastatic RCC or STS for which pazopanib was an appropriate therapy.
AR-42 was taken orally once per day on 3 non-consecutive days each week during the first 3 weeks of each 4-week cycle. Pazopanib was taken by mouth once daily continuously during each cycle.
A modified 3+3 dose-escalation design was to be followed until the maximum tolerated doses (MTDs) were determined. The initial cohort of patients were assigned to an AR-42 dose of 20 mg taken once per day on 3 non-consecutive days during the first 3 weeks of each 4-week cycle and a pazopanib dose of 600 mg once daily continuously. Additional patients would be enrolled until a total of 12 patients were treated at the MTDs.
The protocol specifies a dose escalation plan that initially impacts only the pazopanib dose. The starting dose of pazopanib (600 mg) was planned to be escalated early so that the FDA-approved full dose of pazopanib (800 mg) would be reached before escalating the AR-42 dose. In subsequent dose-escalation steps, the dose of AR-42 was planned to be increased in 10-mg increments from a starting dose of 20 mg to a maximum dose of 40 mg.
If the number of Dose-Limiting Toxicities (DLT) showed that the MTD was exceeded with a pazopanib dose of 800 mg , the pazopanib dose was planned to be decreased to 600 mg and the AR-42 dose increased in 10-mg increments regardless of relationship of the DLT to one or both study medications.

结局指标
主要结局
The Recommended Phase 2 Doses (RP2Ds) of AR-42 and Pazopanib When Given in Combination.
时间窗: 1 month
To determine the recommended phase 2 doses (RP2Ds) for AR-42 and pazopanib that are the same as or less than the maximum tolerated doses (MTDs). The dose-limiting toxicity (DLT) evaluation period will be the first treatment cycle. Patients must have taken a minimum of 6 AR-42 doses and a minimum of 21 pazopanib doses during cycle 1 to be considered evaluable for DLT, if DLT has not been observed at the delivered dose. Patients' treatment dose level, dose modification, evaluability for DLT, and DLTs will be listed and summarized by basic descriptive statistics such as frequency and proportion. The maximum tolerated dose(MTDs)/recommended phase 2 doses (RP2Ds) will be found based on the criteria in the protocol.
