A Phase I, Open-Label, Multi-center Study to Assess the Safety, Tolerability and Pharmacokinetics of AZD6244 (ARRY-142886)

• PK of AZD6244 and selected chemotherapies. [ Time Frame: Cycle 1 Day 3 and Cycle 2 day 1 ] [ Designated as safety issue: No ]
  The PK parameters will be derived using noncompartmental analysis. The maximum plasma concentrations (Cmax) and the time to reach the maximum plasma concentrations (tmax) will be determined by visual inspection of the plasma concentration-time profiles. The area under the plasma concentration-time curve from zero to 12 hours post dose, AUC(0-12), will be calculated by the linear trapezoidal rule. Where more than one maxima occurs, the reported value will be assigned to the first occurrence.
• Define highest tolerated dose of AZD6244 when in combination with selected chemotherapies. [ Time Frame: 28 days + ] [ Designated as safety issue: No ]
  The starting dose of AZD6244 in each arm will be 50mg. Continuous dosing (commencing Cycle 1/Day 3 for docetaxel and dacarbazine and Cycle 1/Day 8 for erlotinib and temsirolimus) will be BD. The AZD6244 dose may be maintained or reduced.
• Tumor response. [ Time Frame: 28 days + ] [ Designated as safety issue: No ]
  To make a preliminary assessment of tumor response as measured by Objective Response Rate (ORR) per investigator's assessment using Response Evaluation Criteria in Solid Tumors (RECIST) when AZD6244 Hyd-Sulfate is given in combination with standard doses of selected chemotherapies.

• PK of AZD6244 and selected chemotherapies.
• Define highest tolerated dose of AZD6244 when in combination with selected chemotherapies.
• Tumor response.
• Identify factors which may influence the sensitivity to AZD6244 or agents used in combination

This study is being conducted to determine if a combination of AZD6244 given orally twice a day with standard doses of selected chemotherapies will be safe and tolerable for cancer patients with advanced solid tumors. The highest tolerated dose of AZD6244 in combination with selected chemotherapies will be evaluated. The study will also investigate how AZD6244 in combination with standard chemotherapies are absorbed, distributed and excreted by the body as well as the length of time that the drugs remain in the body. Initial and periodic assessments will establish patient response to the combination therapies.
