This value of troponin of ≥5 times above the institutional upper limits of normal value must be noted within 10 days prior to potential randomization. The 10-day period can be in the outpatient or inpatient setting. For example, a participant with a troponin value that on one occasion was ≥5 times the upper limits of institutional normal in the 10-day window prior to potential randomization (whether in the inpatient or outpatient setting), but later decreases below that threshold, typically due to starting corticosteroids, would still be considered eligible; 8.

(NOTE: For the purposes of exclusion, LMD is a clinical diagnosis, defined as positive CSF cytology and/or equivocal radiologic or clinical evidence of leptomeningeal involvement. Patients with leptomeningeal symptoms in the setting of leptomeningeal enhancement by imaging (MRI) would be considered to have LMD even in the absence of positive CSF cytology, unless a parenchymal lesion can adequately explain the neurologic symptoms and/or signs. In contrast, an asymptomatic or minimally symptomatic patient with mild or nonspecific leptomeningeal enhancement (MRI) would not be considered to have LMD. In that patient, CSF sampling is not required to formally exclude LMD, but can be performed at the investigator's discretion based on level of clinical suspicion.) 3.

1. New disabling neurological deficit attributable to new ischemic stroke. 2. Minimum lesion diameter of 1.5cm on qualifying imaging. If lesion not visible on imaging, NIHSS must be greater than 4. 3. Non-valvular atrial fibrillation (paroxysmal, persistent, or permanent). 4. Not currently anticoagulated and/or will not be anticoagulated prior to starting their NOAC at the randomized time of initiation (except for DVT prophylaxis). Note: Patients who had been taking an anticoagulant prior to their qualifying index event (for any reason) are eligible for START, assuming the drug is no longer having a therapeutic effect in the patient's system by 48 hours from stroke onset. 5. Treating physician plans to anticoagulate with a FDA-approved novel oral anticoagulant (NOAC): apixaban, dabigatran, edoxaban, or rivaroxaban, or other FDA-approved NOAC. 6. Qualifying brain CT or MRI scan < 48hr from stroke onset (time last known well). If patient has been treated with thrombolytic or endovascular therapy for this stroke, then the qualifying scan is that which is performed after therapy to rule out clinically significant hemorrhagic transformation. 7. Ability to randomize within 60 hours of symptom onset. 1. Any clinical or imaging evidence of spontaneous intracranial hemorrhage in the previous 6 months. Note: Patients with hemorrhagic transformation of current or previous ischemic stroke may be included per Investigator's judgment. Sporadic microbleeds may be included per Investigator's judgment. As a general recommendation, a cerebral microbleed is considered to be ≤ 5mm, but sometimes up to 10mm, in greatest diameter on gradient recalled echo (GRE), or T2*, MRI sequences. Any blood visualized on a CT will be classified as a macrobleed. 2. Infarct volume (estimated) is greater than 50% of middle cerebral artery territory on qualifying scan. If the full extent of the lesion is not visible, any patient with a NIHSS > 23 must be excluded. Note: The lesion does not need to be restricted to the mCA, but if the lesion volume is estimated to be greater than half of the mCA territory, the patient should be excluded. Note: In non-EVT patients, any NIHSS following the index stroke may be used to qualify the patient for START. For example, a patient that presents with a NIHSS of 10 who then receives tPA and improves to a NIHSS of 2 is still eligible for START. For patients whom had endovascular therapy, the qualifying NIHSS assessment is that which is obtained with their qualifying scan following therapy. 3. Anticipated need for major surgery over the next 30 days that would require delay, discontinuation, or extended suspension of anticoagulant of more than 5 days. 4. Symptomatic edema expected from size and location of ischemic stroke. 5. Decreased level of consciousness present or expected. 6. Life expectancy less than 90 days. 7. Follow-up in person or by telephone for 90 days is not feasible.

Patients enrolled to Phase 1 portion of the study and tumor specific cohorts must have measurable disease as defined by RECIST version 1.1 or modified RANO criteria for CNS disease or INRC for neuroblastoma. Patients with EWS enrolled to Phase 2 portion of the study are eligible with evaluable disease (eg, bone only disease with no soft tissue component). 8. Recovered to CTCAE Grade ≤1, or to baseline, from any non-hematological acute toxicities of prior surgery, chemotherapy, immunotherapy, radiotherapy, differentiation therapy or biologic therapy, with the exception of alopecia. 9.
