Dose Escalation of Icotinib in Advanced Non-small Cell Lung Carcinoma (NSCLC) Patients Evaluated as Stable Disease

An Open-label, Randomized, Multicenter, Phase II Trial to Evaluate the Safety and Efficacy of Dose Escalation of Icotinib in Advanced or Metastatic NSCLC Patients After 8 Weeks Routine Therapy Evaluated as Stable Disease

The primary purposes of this study are to assess the safety and efficacy of using high doses of the drug Icotinib (Conmana) as a way to treat patients with non-small cell lung cancer that achieve stable disease after 8 weeks routine therapy.

This is a multi-center phase II randomized controlled study to assess the safety and efficacy of using high doses of the drug Icotinib (Conmana) as a way to treat patients with non-small cell lung cancer that achieve stable disease after 8 weeks routine therapy by PFS, as well as OS and DCR. The adverse events and adverse reaction are evaluated as well.

• Signed and dated informed consent before the start of specific protocol procedures.

Exclusion Criteria:

• Allergic to icotinib
• Patients with metastatic brain tumors with symptoms.
