Completed

• Conditions: Advanced Solid Tumors

• Proteinuria ≥1+ by routine urinalysis (participants with a protein value of ≤500 milligrams (mg) confirmed by a 24-hour urine collection are eligible)
• Pregnant [confirmed by serum beta human chorionic gonadotropin (βHCG)] or breast feeding
• History of prior treatment with other agents specifically targeting IGFRs

• Study Design: SEQUENTIAL

Arm && Interventions

Group	Intervention	Description
IMC-A12	IMC-A12	All participants will receive intravenous (I.V.) infusions of IMC-A12, with the dose depending on which cohort they are enrolled into. A minimum of three participants will be enrolled in each cohort. When all participants complete a cohort, dose escalation to the next cohort will occur.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Adverse Events (AEs) or Deaths	Enrollment to study completion up to 215 weeks	Data presented are the number of participants who experienced serious adverse events (SAEs), other non-serious AEs and deaths during the study including the 30-day follow-up. A summary of SAEs and other non-serious AEs, regardless of causality, is located in the Reported Adverse Event module.
Maximum Tolerated Dose (MTD)	6 weeks	The MTD was defined as the dose preceding the dose level at which 2 participants experienced a dose-limiting toxicity (DLT). A DLT was defined as any Grade 3 or 4 hematologic or nonhematologic toxicity based on Common Terminology Criteria for AE (CTCAE), excluding alopecia, which was considered by the investigator to be definitely, probably, or possibly related to IMC-A12.

Secondary Outcome Measures

Name	Time	Method
Half-Life (t1/2) of IMC-A12 Following Multiple Doses	Predose, 0.5, 1, 2, 4, 8, 24, 48, 96, 168, 264 and 336 hours after the infusion of Cycle 1	Half-Life (t1/2) is the time measured for the plasma concentration of the drug to decrease by one half. The analysis was not performed for the 6 mg/kg and 10 mg/kg dosing groups due to insufficient PK data.
Maximum Concentration (Cmax) of IMC-A12 Following Multiple Doses	Predose, 0.5, 1, 2, 4, 8, 24, 48, 96, 168, 264 and 336 hours after the infusion of Cycle 1
Volume of Distribution of IMC-A12 at Steady State (Vss) Following Multiple Doses	Predose, 0.5, 1, 2, 4, 8, 24, 48, 96, 168, 264 and 336 hours after the infusion of Cycle 1	Vss is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug at steady-state. The analysis was not performed for the 6 mg/kg and 10 mg/kg dosing groups due to insufficient PK data.
Observed Serum Concentration of IMC-A12 at 168 Hour Post End of Infusion Following Multiple Doses	Predose, 0.5, 1, 2, 4, 8, 24, 48, 96, 168, 264 and 336 hours after the infusion of Cycle 1
Area Under the Serum Concentration Versus Time Curve of IMC-A12 During One Dosing Interval (AUCτ) Following Multiple Doses	Predose, 0.5, 1, 2, 4, 8, 24, 48, 96, 168, 264 and 336 hours after the infusion of Cycle 1
Clearance Rate of IMC-A12 at Steady State (CLss) Following Multiple Doses	Predose, 0.5, 1, 2, 4, 8, 24, 48, 96, 168, 264 and 336 hours after the infusion of Cycle 1	CLss is the volume of plasma (or blood) from which the drug is completely removed, or cleared, in a given time at steady-state.
Serum Anti-IMC-A12 Antibody Assessment (Immunogenicity)	Before the last infusion of each treatment cycle	Analysis was not performed due to lack of available assay.
Number of Participants With Best Overall Response	Enrollment to study completion up to 215 weeks	Stable Disease (SD) is neither sufficient shrinkage to qualify for partial response (PR) nor sufficient increase to qualify for progressive disease (PD). PR and PD were assessed by investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) criteria version 1.0. PR is ≥30% decrease in sum of longest diameter of target lesions. PD is ≥20% increase in sum of longest diameter of target lesions and/or a new lesion. Participants with a global deterioration of their health status requiring discontinuation of treatment without objective evidence of disease progression at that time were to be reported as "symptomatic deterioration"
