Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Participants With Dose Limiting Toxicities (DLT) | DLTs were evaluated by the Dose Level Review Team (DLRT). A DLT was defined as any grade >=3 adverse event occurring during a DLT time window (21 day period from the initial administration of AMG 820 and pembrolizumab in combination), and if judged by the investigator to be related to the administration of AMG 820 and/or pembrolizumab. | The DLT evaluation period was Day 1 to Day 21 | |
Primary | Participants With Treatment -Emergent Adverse Events (TEAEs) | TEAEs include any adverse event starting on or after the first dose of AMG 820 or pembrolizumab. Relation to study drugs was determined by the investigator. Adverse events (AEs) were graded by the investigator according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 4.0, where Grade 1 = mild AE, Grade 2 = moderate AE, Grade 3 = severe AE, Grade 4 = life-threatening AE, and Grade 5 = death due to AE. Errors in the case report form design resulted in investigators misunderstanding the CTCAE definition for severity grade 5. Therefore data are not reported for severity grade 5. Readers are referred to the 'Fatal TEAE' line in the table below for counts of participants who died during the TEAE timeframe. | Day 1 up to 207 days for Part 1 and Day 1 up to 572 days for Part 2 | |
Primary | Participants With Treatment -Emergent Adverse Events (TEAEs) Related to AMG 820 Treatment | TEAEs include any adverse event starting on or after the first dose of AMG 820 or pembrolizumab. Relation to study drugs was determined by the investigator. Adverse events (AEs) were graded by the investigator according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 4.0, where Grade 1 = mild AE, Grade 2 = moderate AE, Grade 3 = severe AE, Grade 4 = life-threatening AE, and Grade 5 = death due to AE. Errors in the case report form design resulted in investigators misunderstanding the CTCAE definition for severity grade 5. Therefore data are not reported for severity grade 5.

Primary | Participants With Treatment -Emergent Adverse Events (TEAEs) Related to Pembrolizumab Treatment | TEAEs include any adverse event starting on or after the first dose of AMG 820 or pembrolizumab. Relation to study drugs was determined by the investigator. Adverse events (AEs) were graded by the investigator according to National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 4.0, where Grade 1 = mild AE, Grade 2 = moderate AE, Grade 3 = severe AE, Grade 4 = life-threatening AE, and Grade 5 = death due to AE.

Primary | Objective Response Rate (ORR) Per Immune-Related Response Evaluation Criteria in Solid Tumors (irRECIST) | ORR was defined as the percentage of participants with a best overall response of complete response or partial response assessed by the investigator using immune-related Response Evaluation Criteria in Solid Tumors (irRECIST). Response was based on the size of tumors assessed by computed tomography (CT) or magnetic resonance imaging (MRI). During treatment radiographic imaging was performed at Week 10 and repeated at least every 10 weeks until disease progression. Complete response (iCR): Disappearance of all lesions (whether measurable or not and whether baseline or new) and confirmation by a repeat, consecutive assessment no less than 4 weeks from the date first documented was required. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. Partial response (iPR): Decrease in tumor burden = 30% relative to baseline. Confirmation by a consecutive assessment at least 4 weeks after first documentation required. |
Baseline: Day -28; Treatment: up to Month 13.7 | |
Secondary | Time to Response (TTR) Per Immune-Related Response Evaluation Criteria in Solid Tumors (irRECIST) For Participants Who Responded | Time to response was defined as the time from first dose of AMG 820 until first documented complete or partial response per irRECIST divided by 365.25 days/12. | Day 1 up to Month 16 (max time to censoring) | |
Secondary | Time to Progression (TTP) for Participants Who Had Progressive Disease | Time to progression was defined as the time from first dose of AMG 820 until first documented progressive disease per irRECIST divided by 365.25 days/12. | Day 1 up to 14.4 months (max time to censoring) | |
Secondary | Kaplan-Meier Estimates for Overall Survival (OS) at Month 6 and Month 12 | Overall survival time was calculated as the number of days from the first administration of AMG 820 to date of death or censoring divided by (365.25/12). Data are reported as the percentage of participants who were alive at Month 6 and Month 12. | Day 1 up to Month 6 or Month 12 | |
Secondary | Kaplan-Meier Estimates for Progression-Free Survival (PFS) as Per irRECIST at Month 6 and Month 12 | Progression-free survival time was calculated as the number of days from the first administration of AMG 820 to date of progressive disease or death or censoring divided by (365.25/12). Data are reported as the percentage of participants who were alive and progression-free at Month 6 and Month 12. | Day 1 up to Month 6 or Month 12 | |
