Study of Atezolizumab in Combination With Cobimetinib in Participants With Locally Advanced or Metastatic Solid Tumors

This study evaluates the combination of MPDL3280A and cobimetinib as a treatment for a type of cancer called a "solid tumor," that has certain characteristics. Solid tumors are an abnormal lump of tissue that is growing (ie, not "benign"), and are usually a serious health risk. Different types of solid tumors may be identified more specifically by the type of cells they came from, for instance, sarcomas, carcinomas, or lymphomas. This study s testing MPDL3280A and cobimetinib in combination in people whose tumors are advanced (difficult to treat); metastatic (growing and spreading); and/or has returned, and for which there is no recognized or approved standard treatment.
