Abstract Text

IMC-18F1 (icrucumab), a human monoclonal antibody against vascular endothelial growth factor receptor-1 (VEGFR-1), potently inhibits ligand-dependent phosphorylation of VEGFR-1 and downstream signaling, making icrucumab an attractive candidate for antitumor activity.The primary objective was to determine the safety profile and maximum tolerated dose of icrucumab in patients with advanced solid tumors that were previously unresponsive to standard therapy or for which no standard therapy was available.In this open-label, dose-escalation, Phase 1 study, patients received icrucumab intravenously weekly at 2, 3, 6, and 12 mg/kg (Cohorts 1-4), every other week (q2w) at 15 mg/kg (Cohort 5), or every third week at 20 mg/kg (Cohort 6). Patients received icrucumab until evidence of progressive disease or other withdrawal criteria were met.Twenty-six patients received icrucumab. The most common adverse events were fatigue, nausea, peripheral edema, anemia, dyspnea, and vomiting. No dose-limiting toxicities (DLTs) were observed in Cohorts 1-5. Two DLTs were observed in Cohort 6 (anemia and hyponatremia), and enrollment was stopped. No patient demonstrated an immunogenic response. Overall, icrucumab exhibited nonlinear pharmacokinetics at doses >6 mg/kg. Six patients (23.1 %) achieved stable disease with median duration of 11.1 weeks (range = 10.3-18.7 weeks); tumor types were thyroid, melanoma, colorectal (3 patients), and small-cell lung cancers.Icrucumab was safely administered weekly at doses of 2-12 mg/kg and q2w at a dose of 15 mg/kg with no DLTs. Based on achievement of stable disease, icrucumab has potential for antitumor activity against advanced solid tumors.

Filtering

Case insensitive filtering will display rows if any text in any cell matches the filter term
Use simple literal full or partial string matches
Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
Click on any column header arrows to sort by that column
Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
