Abstract Text To determine the dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) of the investigational NEDD8-activating enzyme (NAE) inhibitor pevonedistat (TAK-924/MLN4924) and to investigate pevonedistat pharmacokinetics and pharmacodynamics in patients with advanced nonhematologic malignancies.Pevonedistat was administered via 60-minute intravenous infusion on days 1 to 5 (schedule A, n = 12), or days 1, 3, and 5 (schedules B, n = 17, and C, n = 19) of 21-day cycles. Schedule B included oral dexamethasone 8 mg before each pevonedistat dose. Dose escalation proceeded using a Bayesian continual reassessment method. Tumor response was assessed by RECIST 1.0.Schedule A MTD was 50 mg/m(2); based on the severity of observed hepatotoxicity, this schedule was discontinued. Schedules B and C MTDs were 50 and 67 mg/m(2), respectively. DLTs on both these schedules included hyperbilirubinemia and elevated aspartate aminotransferase. There were no grade ≥ 3 treatment-related serious adverse events reported on schedules B or C. Twenty-three (74%) evaluable patients on schedules B and C had stable disease. Intermittent dexamethasone use did not significantly influence pevonedistat pharmacokinetics. NAE inhibition by pevonedistat was demonstrated in multiple tumor types via IHC detection of pevonedistat-NEDD8 adduct and accumulation of Cullin-RING ligase substrates CDT1 and NRF2 in tumor biopsies.Pevonedistat was generally well tolerated on a day 1, 3, 5 schedule every 3 weeks with an MTD between 50 mg/m(2) and 67 mg/m(2). DLTs were predominantly hepatic enzyme elevations. Pharmacodynamic studies demonstrated that pevonedistat inhibited NAE in tumors.

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (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 a longer phrase which contains spaces "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.
