Atezolizumab and Cobimetinib in Treating Patients With Metastatic, Recurrent, or Refractory Non-small Cell Lung Cancer
Bu çalışma, metastatik, nüks etmiş veya tedaviye dirençli küçük hücreli dışı akciğer kanseri (non-small cell lung cancer) olan hastalarda Atezolizumab ve Cobimetinib ilaçlarının birlikte kullanımını değerlendiriyor. Katılım için tümörde KRAS mutasyonu durumu bilinen ve daha önce anti-PD-1 veya anti-PD-L1 tedavisine dirençli olduğu görülen hastalar uygundur. Faz 2 aşamasında yürütülmekte; şu an katılımcı almamakta ancak devam etmektedir (active, not recruiting).
