Abstract Text

This "3+3" phase I study evaluated the safety, biologic, and clinical activity of lenvatinib, an oral multikinase inhibitor, in patients with solid tumors.Ascending doses of lenvatinib were administered per os twice daily in 28-day cycles. Safety and response were assessed for all patients. Angiogenic and apoptotic factors were tested as possible biomarkers in an expanded melanoma cohort.Seventy-seven patients were treated in 3 cohorts: 18 with intermittent twice-daily dosing (7 days on, 7 days off) of 0.1-3.2 mg; 33 with twice-daily dosing of 3.2-12 mg; and 26 with twice-daily dosing of 10 mg (expanded melanoma cohort). Maximum tolerated dose was established at 10 mg per os twice daily. Prominent drug-related toxicities included hypertension (43%), fatigue (42%), proteinuria (39%), and nausea (25%); dose-limiting toxicities included hypertension, fatigue, and proteinuria. Twelve patients (15.6%) achieved partial response (PR, n = 9) or unconfirmed PR (uPR, n = 3), and 19 (24.7%) achieved stable disease (SD) ≥23 weeks. Total PR/uPR/SD ≥23 weeks was 40.3% (n = 31). Responses (PR/uPR) by disease were as follows: melanoma, 5 of 29 patients (includes 1 patient with NRAS mutation); thyroid, 3 of 6 patients; pancreatic, 1 of 2 patients; lung, 1 of 1 patients; renal, 1 of 1 patients; endometrial, 1 of 4 patients; and ovarian, 1 of 5 patients. AUC(0-24) and C(max) increased dose proportionally. In multivariate Cox proportional hazard model analyses, increased baseline systolic blood pressure and decreased angiopoietin-1 ratio (2 hours:baseline) were associated with longer progression-free survival (PFS) in the expanded melanoma cohort (P = 0.041 and P = 0.03, respectively).The toxicity profile, pharmacokinetics, and antitumor activity of lenvatinib are encouraging. Decreases in the angiopoietin-1 ratio correlated with longer PFS in melanoma patients.

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.
