Assess Efficacy & Safety of Selumetinib in Combination With Docetaxel in Patients Receiving 2nd Line Treatment for v-Ki-ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) Positive NSCLC
The purpose of this study is to assess the efficacy of selumetinib in combination with docetaxel (75mg/m2) vs placebo in combination with docetaxel (75mg/m2) in patients with locally advance or metastatic NSCLCs that harbor mutations of KRAS. This study will also assess the PK, safety, patient reported outcomes (PRO) and tolerability profile of the selumetinib/docetaxel combination, compared to placebo in combination with docetaxel

Who may be able to participate
The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.
- Provision of signed, written and dated informed consent prior to any study specific procedures
- Male or female, aged 18 years or older
- Histological or cytological confirmation of locally advanced or metastatic NSCLC (IIIB-IV)
- KRAS mutation positive tumour sample as determined by the designated testing laboratory
- Failure of 1st line anti-cancer therapy due to radiological documentation of disease progression in advanced disease or subsequent relapse of disease following 1st line therapy
- Mixed small cell and non-small cell lung cancer histology.
- Received \>1 prior anti-cancer drug regimen for advanced or metastatic NSCLC. Patients who develop disease progression while on switch maintenance therapy (maintenance using an agent not in the first-line regimen) will not be eligible.
- Receiving or have received systemic anti-cancer therapy within 30 days prior to starting study treatment
- Other concomitant anti-cancer therapy agents excepts steroids
- Prior treatment with a Mitogen-Activated protein Kinase (MEK) inhibitor or any docetaxel-containing regimen (prior treatment with paclitaxel is acceptable).
