Abstract Text Capmatinib is a highly specific, potent and selective MET inhibitor. This was an open-label, multicenter, dose-escalation, phase I study conducted in Japanese patients with advanced solid tumors (not selected based on their MET status). The primary objective was to determine the maximum tolerated dose (MTD) and/or highest studied dose being safe. Secondary objectives included safety, pharmacokinetics and preliminary antitumor activity. Dose escalation was guided by a Bayesian Logistic Regression Model dependent on dose-limiting toxicities (DLT) in cycle 1. Of 44 adult Japanese patients with confirmed advanced solid tumors enrolled, 29 received capmatinib capsules (doses ranging from 100 mg once daily [q.d.] to 600 mg twice daily [b.i.d.]) and 15 received tablets (200 mg b.i.d. and 400 mg b.i.d.). DLT occurred in two patients: grade 2 suicidal ideation (600 mg b.i.d. capsule) and grade 3 depression (400 mg b.i.d. tablet). MTD was not reached. The highest studied dose determined to be safe as tablet was 400 mg b.i.d., whereas it is not yet determined for capsules. Most common adverse events suspected to be drug-related were increased blood creatinine, nausea, decreased appetite, vomiting and diarrhea. Following repeated daily dosing up to day 15 by q.d. or b.i.d. regimen using capsules, median time to reach maximum plasma drug concentration (Tmax ) was 1.0-4.0 hours; absorption was more rapid after dosing using tablets, with median Tmax of 1.0 hour on both days 1 and 15. Eight patients had a best overall response of stable disease. These data support further clinical development of capmatinib.

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.
