primary Outcomes

description
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.
measure
Participants With Dose Limiting Toxicities (DLT)
time Frame
The DLT evaluation period was Day 1 to Day 21
description
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.

Participants With Treatment -Emergent Adverse Events (TEAEs)
time Frame
Day 1 up to 207 days for Part 1 and Day 1 up to 572 days for Part 2

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.

time Frame
Baseline: Day -28; Treatment: up to Month 13.7

Full study description

brief Summary: A multi-center Phase 1b/2 study testing the combination of AMG 820 and pembrolizumab in subjects with select advanced solid tumors.
detailed Description: Phase 1b is AMG 820 dose determining and aimed at assessing the safety and tolerability of the selected starting dose of AMG 820 in combination with pembrolizumab. Phase 2 of the study will further evaluate safety and tolerability and additionally test whether AMG 820 can enhance the anti-tumor activity observed historically with pembrolizumab alone and/or overcome lack of response to pembrolizumab monotherapy in subjects with select solid tumors.
