Abstract Text This phase I study (ClinicalTrials.gov ID: NCT00424632) evaluated the safe dose, pharmacokinetics, and pharmacodynamics of the aurora kinase A and B inhibitor, PF-03814735. Patients with advanced solid tumours received oral, once-daily (QD) PF-03814735 on Schedule A: days 1-5 (5-100mg); or Schedule B: days 1-10 (40-60mg) of 21-day cycles. Fifty-seven patients were treated: 32 and 25 on Schedules A and B, respectively. Dose-limiting toxicities were: febrile neutropenia (Schedule A); and increased levels of aspartate amino transferase, left ventricular dysfunction, and prolonged low-grade neutropenia (Schedule B). Maximum tolerated doses were 80mg QD (Schedule A) and 50mg QD (Schedule B). Common treatment-related adverse events were mainly mild to moderate and included diarrhoea, fatigue, nausea, and vomiting. Nineteen patients achieved stable disease, which was prolonged in four cases. PF-03814735 was rapidly absorbed and demonstrated linear pharmacokinetics up to 100mg QD; mean terminal half-life ranged from 14.4 to 23.6h. Aurora B activity, assessed by histone H3 phosphorylation in mitotic cells, decreased in tumour tissue from 10/12 patients evaluated (range: -70% to -3%). (18)F-fluorodeoxyglucose positron emission tomography demonstrated metabolic responses in only 1/21 patients. PF-03814735 was generally well tolerated with manageable toxicities, and a recommended phase II dose could be established for both schedules. Aurora B activity was inhibited in tumour tissue, but clinical or metabolic antitumour activity was limited.

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.
