Title Phase I study of pemetrexed with sorafenib in advanced solid tumors.
Abstract Text To determine if combination treatment with pemetrexed and sorafenib is safe and tolerable in patients with advanced solid tumors.Thirty-seven patients were enrolled and 36 patients were treated (24 in cohort A; 12 in cohort B). The cohort A dose schedule resulted in problematic cumulative toxicity, while the cohort B dose schedule was found to be more tolerable. The maximum tolerated dose (MTD) was pemetrexed 750 mg/m2 every 14 days with oral sorafenib 400 mg given twice daily on days 1-5. Because dosing delays and modifications were associated with the MTD, the recommended phase II dose was declared to be pemetrexed 500 mg/m2 every 14 days with oral sorafenib 400 mg given twice daily on days 1-5. Thirty-three patients were evaluated for antitumor activity. One complete response and 4 partial responses were observed (15% overall response rate). Stable disease was seen in 15 patients (45%). Four patients had a continued response at 6 months, including 2 of 5 patients with triple-negative breast cancer.A phase I trial employing a standard 3 + 3 design was conducted in patients with advanced solid tumors. Cohort A involved a novel dose escalation schema exploring doses of pemetrexed every 14 days with continuous sorafenib. Cohort B involved a modified schedule of sorafenib dosing on days 1-5 of each 14-day pemetrexed cycle. Radiographic assessments were conducted every 8 weeks.Pemetrexed and intermittent sorafenib therapy is a safe and tolerable combination for patients, with promising activity seen in patients with breast cancer.


  • 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")


  • 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.

PTEN dec exp Advanced Solid Tumor predicted - sensitive Pemetrexed Disodium + Sorafenib Phase I Actionable In a Phase I clinical trial, low Pten expression or lack of Pten expression was associated with better response to treatment with the combination of Alimta (pemetrexed) and Nexavar (sorafenib) in patients with advanced solid tumors (PMID: 27213589). 27213589
