The total number of participants with high grade treatment related select adverse events.

The total number of participants with high grade select adverse events. High grade is defined as Common Terminology Criteria for Adverse Events (CTCAE) v4.0 Grades 3-4. An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation subject administered study drug and that does not necessarily have a causal relationship with this treatment. Select AEs include Pulmonary toxicity, Gastrointestinal toxicity (diarrhea or colitis, Endocrinopathies, Hepatotoxicity (including asymptomatic LFT elevations), Renal toxicity, Skin toxicity, and Neurological toxicity.

Median Time to onset of any grade select adverse events reported up to 100 days after last dose. An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation subject administered study drug and that does not necessarily have a causal relationship with this treatment. Select AEs include Pulmonary toxicity, Gastrointestinal toxicity (diarrhea or colitis, Endocrinopathies, Hepatotoxicity (including asymptomatic LFT elevations), Renal toxicity, Skin toxicity, and Neurological toxicity.

Median time to resolution of any grade select adverse events reported up to 100 days after last dose. An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation subject administered study drug and that does not necessarily have a causal relationship with this treatment. Select AEs include Pulmonary toxicity, Gastrointestinal toxicity (diarrhea or colitis, Endocrinopathies, Hepatotoxicity (including asymptomatic LFT elevations), Renal toxicity, Skin toxicity, and Neurological toxicity.

Overall Survival (OS) is defined as the time from first dosing date to the date of death. A subject who has not died will be censored at last known date alive. OS will be followed continuously while subjects are on treatment and every 3 months via in-person or phone contact after subjects discontinue the study drug.

ORR is defined as the percentage of subjects with a best overall response (BOR) of confirmed complete response (CR) or partial response (PR). CR is defined as the disappearance of all target lesions; PR is defined by at least a 30% decrease in the sum of the longest diameter of target lesions. ORR as assessed by the investigator will be reported.
