Official title

A Phase 1 / 2, Dose Escalation Study of Intravenous TK216 in Patients With Relapsed or Refractory Ewing Sarcoma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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 in monotherapy and in combination with vincristine to assess the potential of TK216 for further development.
