Trial Outcomes & Findings for Phase I Study of Dalotuzumab (MK-0646) in Combination With Cetuximab and Irinotecan in Participants With Colorectal Cancer (MK-0646-016) (NCT NCT00925015)

NCT ID: NCT00925015

Last Updated: 2018-08-15

Results Overview

To be declared a DLT an adverse experience had a causality related to study therapy. DLTs could be adverse experiences possibly, probably, or definitely related to study therapy by the Investigator, and included the following : Grade 4 neutropenia lasting \>= 5 days; Grade 3 or 4 neutropenia with fever \>38.5°C; Grade 4 thrombocytopenia; Grade 3 or Grade 4 non-hematologic toxicity, except inadequately treated diarrhea, nausea and vomiting, rash, hyperglycemia, and transient abnormality of electrolytes. Anemia, infusion reactions, hypersensitivity reactions, and adverse experiences not-related to study therapy did not qualify as DLTs.

PRIMARY outcome

Timeframe: Four weeks of Cycle 1 treatment (up to 28 days)

Population: Participants treated with study medication. The Dmab 10 mg/kg - Cetux/Irin arm was not evaluated. In the Cetux/Irin - Dmab 10 mg/kg (DDI) arm two participants were not analyzed because one had febrile neutropenia (Grade 3) before the first treatment, and the second had a skin toxicity (Grade 3) before the DLT evaluation period.

To be declared a DLT an adverse experience had a causality related to study therapy. DLTs could be adverse experiences possibly, probably, or definitely related to study therapy by the Investigator, and included the following : Grade 4 neutropenia lasting \>= 5 days; Grade 3 or 4 neutropenia with fever \>38.5°C; Grade 4 thrombocytopenia; Grade 3 or Grade 4 non-hematologic toxicity, except inadequately treated diarrhea, nausea and vomiting, rash, hyperglycemia, and transient abnormality of electrolytes.

Population: Participants treated with study medication.

An AE is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which is temporally associated with the use of the SPONSOR's product, is also an AE.

Population: All treated participants, excluding those without measurable data.

Sera were collected from participants prior to administration of the first dose of study drug, every 6 weeks during the study period, then 4 weeks, 8 weeks and 12 weeks post-treatment. A sandwich format enzyme-linked immunosorbent assay (ELISA) was used to detect the presence of HAHA in serum.
