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.
The study has been expanded to explore single agent TK216 for longer treatment duration. Approximately 26 patients will be enrolled in this Cohort.
Please note: This study has been terminated and is no longer enrolling patients.

Once an appropriate patient has been identified, a 30-day screening period began and evaluated eligibility.
The study was executed in several Parts:
Part 1: Dose Escalation Segment (Cohorts 1-6) Part 2: Schedule Escalation Segment (Cohorts 7-9) Part 3: Expansion Segment (Cohort 10) Part 4: Dose and Schedule Evaluation Segment (Cohort 11)
Note: For purposes of result summaries, Cohorts 1-8 pooled, Cohorts 9 & 10 pooled, and Cohort 11 will be displayed.
85 subjects were enrolled in this study across eight North American centers. The pathologic diagnoses were confirmed at each enrolling center. Most patients were heavily pretreated, with the median number of prior therapies being 3.0 (range, 1-10). The gender and ethnicity of the enrolled patients matched ES's prevalence in the U.S. population.

TK216 was advanced as a novel inhibitor of EWS::FLI1 despite pharmacologic challenges to creating an oral formulation. In vivo studies showed that continuous exposure to TK216 was required for optimal efficacy.47 This continuous infusion was a logistical challenge and negatively affected study enrollment rates. Another limitation of this study was the lack of a pharmacodynamic readout of TK216 activity.

| EG005 | 200 mg/m^2 (14 Days) | Dose Escalation Segment (Cohorts 1-6) was an open label, "3+3" patient enrollment scheme, sequential allocation, dose finding allocation of the sequential allocation of TK216 monotherapy. The length of TK216 infusion for all dose escalation cohorts was 7 days. A lower intermediate dose of 220mg/m2 /day for 7 days was determined to be the maximum tolerated dose (MTD) for the 7-day continuous infusion of TK216 | 2 | 4 | 1 | 4 | 4 | 4 |
| EG006 | 220 mg/m^2 (7 Days) | Schedule Escalation Segment (Cohorts 7-9) was an open label, "3+3" patient enrollment scheme, sequential allocation of the increase in length of infusion of TK216 monotherapy. Following the first two cycles, vincristine could be added as tolerated up to 2mg on the first day of each cycle. The recommended Phase 2 dose (RP2D) was determined to be 200mg/m2 /day for 14 days followed by a 14-day recovery period, per 28-day cycle | 2 | 3 | 2 | 3 | 3 | 3 |
| EG007 | 220 mg/m^2 (10 Days) | Schedule Escalation Segment (Cohorts 7-9) was an open label, "3+3" patient enrollment scheme, sequential allocation of the increase in length of infusion of TK216 monotherapy. Following the first two cycles, vincristine could be added as tolerated up to 2mg on the first day of each cycle. The recommended Phase 2 dose (RP2D) was determined to be 200mg/m2 /day for 14 days followed by a 14-day recovery period, per 28-day cycle | 3 | 3 | 1 | 3 | 3 | 3 |
| EG008 | 288 mg/m^2 (7 Days) | Schedule Escalation Segment (Cohorts 7-9) was an open label, "3+3" patient enrollment scheme, sequential allocation of the increase in length of infusion of TK216 monotherapy. Following the first two cycles, vincristine could be added as tolerated up to 2mg on the first day of each cycle. The recommended Phase 2 dose (RP2D) was determined to be 200mg/m2 /day for 14 days followed by a 14-day recovery period, per 28-day cycle | 3 | 7 | 2 | 7 | 7 | 7 |
| EG009 | Expansion | Expansion Segment (Cohort 10) where patients were treated with the schedule for RP2D of TK216 with vincristine 0.75 - 1.5 mg/m2 administered on the first day of each 28-day cycle | 26 | 44 | 21 | 44 | 44 | 44 |
| EG010 | 175 mg/m^2 | Dose and Schedule Evaluation Segment (Cohort 11) where patients received a starting dose of 175mg/m2 /day of TK216 intravenously by continuous infusion for 28 days per cycle. If the patient's tumor response was determined by the Investigator as inadequate after at least one protocol-specified post-baseline assessment and they were not experiencing toxicities at this dose level, the Investigator could increase the dose to 200 mg/m2/day after discussion with the Sponsor. Vincristine (0.75 to 1.5 mg/m2 up to a maximum dose of 2 mg) could be administered in parallel with the TK216 infusion following progressive disease after TK216-01 monotherapy but only after consultation with the Sponsor | 1 | 8 | 5 | 8 | 8 | 8 |
