Brief summary

The objective of this study will be to investigate the safety and tolerability of AZD6244 given monotherapy or in combination with docetaxel as 2nd line therapy in Japanese patients with Advanced Solid Malignancies or Locally Advanced or Metastatic Non-Small Cell Lung Cancer. In addition, the pharmacokinetic profile of AZD6244 will be investigated. Following the combination regimen dose escalation phase (Part A) of the study additional patients may be enrolled to a dose expansion phase (Part B) to refine further the safety, tolerability, pharmacokinetics and biological activity of the combination in this patient population.

Detailed description

The objective of the combination therapy part of this study will be to investigate the safety and tolerability of AZD6244 given in combination with docetaxel as 2nd line therapy in Japanese patients with Locally Advanced or Metastatic Non-Small Cell Lung Cancer (Stage IIIB-IV). In addition, the pharmacokinetic profile of AZD6244 and docetaxel will be investigated. The objective of the monotherapy part of this study will be to investigate the safety and tolerability of AZD6244 given as a monotherapy in Japanese patients with advanced solid malignancies. In addition, the pharmacokinetic profile of monotherapy AZD6244 will be investigated.
