Information provided by (Responsible Party):
Oncternal Therapeutics, Inc
ClinicalTrials.gov Identifier:
NCT02657005
First received: January 12, 2016
Last updated: October 13, 2016
Last verified: October 2016
  Purpose
Ewing sarcoma is characterized by genomic rearrangements resulting in over-expression of ets family transcription factors driving tumor progression. TK216 is designed to inhibit this effect by inhibiting downstream effects of the EWS-FLI1 transcription factor. This study is a first in human study of TK216 in subjects with Ewing sarcoma. The study is designed to establish initial safety and efficacy data to assess the potential of TK216 for further development.
