| NCT00614393 | Study of Dalotuzumab (MK-0646) in Combination With Cetuximab and Irinotecan in Metastatic Colorectal Cancer (MK-0646-004) | PHASE2 | COMPLETED | 558 | — | — | Dec 24, 2007 | Mar 7, 2012 | Aug 8, 2018 | - | — |
The OS of participants with metastatic colorectal cancer (CRC) expressing the KRAS wild-type (wtKRAS) tumor genotype (indicating no detection of KRAS mutation) was defined as the time from randomization to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up. OS was analyzed using the Kaplan-Meier method and is reported in months.
The PFS of participants with metastatic CRC expressing the wtKRAS genotype was defined as the time from the first day of study treatment to the first documented disease progression per Response Evaluation Criteria in Solid Tumors version 1.0 (RECIST 1.0) as documented by an independent core laboratory, or death due to any cause, whichever occurred first. Disease progression was defined as either a 20% or greater relative increase in the sum of diameters of target lesions OR an absolute increase of at least 5mm in the sum of lesions or the appearance of new lesions. PFS was analyzed using the Kaplan-Meier method and is reported in months.
An adverse event (AE) was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure. (Grade 3=Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care activities of daily living. Grade 4=Life-threatening consequences; urgent intervention indicated. Grade 5=Death related to AE.) Participants were monitored for AEs until the earlier of study discontinuation or 30 days after dalotuzumab/placebo discontinuation. AE grades were assessed using the National Cancer Institute (NCI) CTCAE, version 3.0.
An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure. (Grade 3=Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care activities of daily living. Grade 4=Life-threatening consequences; urgent intervention indicated. Grade 5=Death related to AE.) Drug-related AEs were those AEs that were possibly, probably, or definitely related to study drug or protocol-specified procedures. Participants were monitored for AEs related to dalotuzumab or placebo until the earlier of study discontinuation or 30 days after dalotuzumab/placebo discontinuation. AE grades were assessed using the NCI CTCAE, version 3.0.
An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure. The percentage of participants who discontinued study drug due to an AE is presented.
The percentage of participants who experienced an AE of infusion site reaction is presented.
