Medical Director

This clinical study evaluates the safety, tolerability, pharmacokinetics, and immunogenicity of dalotuzumab (MK-0646) in participants with relapsed or refractory locally advanced or metastatic solid tumors using once weekly and once every other week dose infusion regimens.

The primary study hypothesis is that administration of dalotuzumab as a once weekly and an every other week infusion will be generally safe and well tolerated

Toxicity was graded and recorded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. DLTs were defined as the occurrence of any of the following events when judged to be related to the study medication: Grade 4 neutropenia; Grade 3 neutropenia with fever \>38.5°C; Grade 4 thrombocytopenia; Grade 3 or Grade 4 non-hematologic toxicity, except alopecia and inadequately treated diarrhea, nausea and vomiting. The number of participants who experienced a DLT is presented.

An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study treatment, whether or not considered related to the use of study treatment. Any worsening (i.e. any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which was temporally associated with the use of study treatment, was also an AE. The number of participants who experienced at least one AE is presented.

The number of participants who discontinued study treatment due to an AE is presented.

Cmax was assessed on Week 2 (Day 8) for the Dalotuzumab 5 mg/kg and Dalotuzumab 10 mg/kg treatment groups and on Week 3 (Day 15) for the Dalotuzumab 15 mg/kg/7.5 mg/kg treatment group.

AUC0-∞ was assessed on Week 2 (Day 8) for the Dalotuzumab 5 mg/kg and Dalotuzumab 10 mg/kg treatment groups and on Week 3 (Day 15) for the Dalotuzumab 15 mg/kg/7.5 mg/kg treatment group.

Tmax was assessed on Week 2 (Day 8) for the Dalotuzumab 5 mg/kg and Dalotuzumab 10 mg/kg treatment groups and on Week 3 (Day 15) for the Dalotuzumab 15 mg/kg/7.5 mg/kg treatment group.

t1/2 was assessed on Week 2 (Day 8) for the Dalotuzumab 5 mg/kg and Dalotuzumab 10 mg/kg treatment groups and on Week 3 (Day 15) for the Dalotuzumab 15 mg/kg/7.5 mg/kg treatment group.

CL of dalotuzumab was assessed on Week 2 (Day 8) for the Dalotuzumab 5 mg/kg and Dalotuzumab 10 mg/kg treatment groups and on Week 3 (Day 15) for the Dalotuzumab 15 mg/kg/7.5 mg/kg treatment group.

Vss was assessed on Week 2 (Day 8) for the Dalotuzumab 5 mg/kg and Dalotuzumab 10 mg/kg treatment groups and on Week 3 (Day 15) for the Dalotuzumab 15 mg/kg/7.5 mg/kg treatment group.

Formation of HAHAs may block efficacy by substantially increasing the clearance of dalotuzumab and limit the possibility of future dalotuzumab therapy. The occurrence of HAHAs in the sera of dalotuzumab treated participants at any of the serum collection times was assessed.
