Title Single-center study to determine the safety and efficacy of CT-707 in Chinese patients with advanced anaplastic lymphoma kinase-rearranged non-small-cell lung cancer.
Abstract Text It has been proven that ALK-rearranged non-small cell lung cancer (NSCLC) is sensitive to ALK inhibitors while the chemotherapy resistance is unavoidable. In this study, safety and antitumor activity of the novel ALK inhibitor (ALKi) CT-707 were evaluated in Chinese patients with advanced ALK-rearranged NSCLC.This single-center, open-label phase I study recruited adult patients with ALK-rearrangement (confirmed by fluorescence in situ hybridization and/or immunohistochemistry) of locally advanced/metastatic malignancies including NSCLC. This study consisted of two parts: dose escalation and dose expansion. CT-707 was administered orally once a day for 21 days.A total of 13 patients who were treated with CT-707 from 450 to 600 mg (in the dose increasing phase) were enrolled in this trial (two patients were previously treated with crizotinib). There were 12 patients diagnosed with lung adenocarcinoma and one patient with malignant pleural mesothelioma. After treatment, grade 3 diarrhea (600 mg once a day) was found as dose-limiting toxicity (DLT).The most common adverse events included diarrhea (92%), elevated aspartate aminotransferase (61%), elevated alanine aminotransferase (54%), hair loss (38%), and vomiting (31%). The overall response rate was 77% (10/13). Among all patients, four of the five patients who did not receive any treatment, one of the two patients who had received treatments with crizotinib, and five of the six patients who received standard chemotherapy achieved partial response (PR). One patient reached a complete remission (CR).This study indicated that CT-707 is clinically effective as a new antitumor drug for Chinese lung adenocarcinoma patients with ALK rearrangement. It is safe and reliable and the dose-expansion phase recruitment has started.


  • 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.

ALK rearrange malignant pleural mesothelioma no benefit Conteltinib Case Reports/Case Series Actionable In a Phase I trial, Conteltinib (CT-707) treatment resulted in disease progression after 1 cycle in a patient with ALK-rearranged malignant pleural mesothelioma (PMID: 32181989). 32181989
ALK rearrange lung adenocarcinoma predicted - sensitive Conteltinib Phase I Actionable In a Phase I trial, Conteltinib (CT-707) demonstrated safety and preliminary efficacy, resulting in an overall response rate of 77% (10/13, 1 complete response, 9 partial responses) and a disease control rate of 85% (11/13) in patients with ALK-rearranged lung adenocarcinoma (n=12) or malignant pleural mesothelioma (n=1), median progression-free survival was 13 months in patients with lung adenocarcinoma (PMID: 32181989). 32181989
