• Conditions: Colorectal Cancer; Locally Advanced; Sarcoma; Solid Tumors; Non-Small Cell Lung Cancer; Ovarian Cancer; Pancreatic Cancer; Metastatic Cancer
• Interventions: Biological: AMG 479; Biological: AMG 655

• Registration Number: NCT00819169

Brief Summary

This is a multi-center, 2-part phase 1b/2 study of AMG 655 in combination with AMG 479 to be conducted in the United States and Spain.

Part 1 is a dose escalation segment to identify a dose of AMG 655 in combination with AMG 479 that is safe and tolerable.

Part 2 will evaluate the safety and estimate the efficacy of AMG 655 at the dose selected in Part 1 in combination with AMG 479 for the treatment of patients with advanced NSCLC (non-squamous histology; squamous histology), CRC, pancreatic cancer, ovarian cancer, and sarcoma.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Dose-limiting Toxicities	Time from first dose up to 24 months	Incidence of adverse events and clinical laboratory abnormalities defined as DLTs. Dose-limiting toxicities included any grade 3 or higher hematologic or nonhematologic toxicity related to conatumumab or the combination of conatumumab with ganitumab except for lymphocytopenia and anemia.
Objective Response Rate	Time from first dose up to 24 months	The objective response rate (ORR) is defined as confirmed complete response or partial response using modified Response Evaluation Criteria in Solid Tumors \[RECIST\]: a complete response is the disappearance of all target lesions; a partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Secondary Outcome Measures

Name	Time	Method
To Evaluate Anti-AMG 655 Antibody Formation and Anti-AMG 479 Antibody Formation	Time from first dose up to 24 months
To Evaluate the Concentration Level of AMG 655	Cycle 1 Day 1 end of infusion; Cycle 3 Day 1 end of infusion (each cycle is 28 days, each infusion is up to 1 hour)	Median, minimum, and maximum concentration of AMG 655 at specified time points.
Time to Response	Time from first dose up to 24 months	Time to response is the time from study day 1 to the first observation of an objective response. Subjects without an objective response are excluded from the analysis of this endpoint. Objective response is defined as a tumor response assessment of either complete response or partial response per modified Response Evaluation Criteria in Solid Tumors (RECIST) and will be determined based on the Investigator-reported assessment only for subjects with measurable disease at baseline. Per RECIST v 1.1: a complete response is the disappearance of all target lesions; a partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
To Evaluate the Concentration Level of AMG 479	Cycle 1 Day 1 end of infusion; Cycle 3 Day 1 end of infusion (each cycle is 28 days, each infusion is up to 1 hour)	Median, minimum, and maximum concentration of AMG 479 at specified time points.
Progression Free Survival	Time from first dose up to 24 months	Progression-free survival is defined as the number of days from study day 1 (first dose of investigational product) to the first observation of disease progression (by modified RECIST; or clinical progression, whichever came first) or death due to any cause. Disease progression by RECIST is defined as at least a 20% increase in the sum of diameters of target lesions in reference to the smallest sum on study and an absolute increase of at least 5 mm; the appearance of any new lesions is also considered progression.
Duration of Response	Time from objective response to 24 months	Duration of response is defined as the number of days between the date of first objective response to the time of the first progressive disease (per modified Response Evaluation Criteria in Solid Tumors \[RECIST\] or clinical progression, whichever occurs first) or death due to any cause. Objective response is defined as a tumor response assessment of either complete response or partial response per modified RECIST where a complete response is the disappearance of all target lesions and a partial response is defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Per RECIST v 1.1, disease progression is defined as at least a 20% increase in the sum of diameters of target lesions in reference to the smallest sum on study and an absolute increase of at least 5 mm; the appearance of any new lesions is also considered progression.
