effusion as determined by echocardiogram (ECHO) or multigated acquisition (MUGA)
scan, and no symptomatic cardiac disease or history of serious ventricular
arrhythmia (ie, ventricular tachycardia or ventricular fibrillation), high-grade
atrioventricular block, or other cardiac arrhythmias requiring anti-arrhythmic
medications (except for atrial fibrillation that is well controlled with
anti-arrhythmic medication)

4. Pulmonary: No clinically significant pleural effusion (per principal investigator
[PI] judgement), and baseline oxygen saturation ≥ 92% on room air,

5. Hematological: absolute neutrophil count (ANC) ≥ 1000/mm3, platelet count ≥
75,000/mm3, and hemoglobin ≥ 8 g/dL

6. Coagulation: International normalized ratio (INR) ≤ 1.5 ULN and activated partial
thromboplastin time (aPTT) ≤ 1.5 ULN. Patients on therapeutic doses of
anticoagulation medication must have INR and/or aPTT ≤ the upper limit of the
therapeutic range for intended use.

10. Able to provide written informed consent.

11. Aged 16-80 years.

12. Weight ≥40 kg.

13. All male and female patients who are able to have children must practice effective
birth control while on study therapy and for up to 3 months post completion of study
therapy. Acceptable forms of birth control for female patients include: hormonal birth
control, intrauterine device, diaphragm with spermicide, condom with spermicide, or
abstinence. Female patients who become pregnant or suspect pregnancy must immediately
notify their doctor. Females patients who become pregnant will be taken off study. Men
who are able to have children must use effective birth control while on the study
therapy.

Acceptable forms of birth control for male patients include: condom with spermicide or
abstinence. If the male patient fathers a child or suspects that he has fathered a
child while on the study, he must immediately notify his doctor.

14. Negative serum or urine beta human chorionic gonadotropin pregnancy test for females
of childbearing potential (defined as not postmenopausal for 24 months or no previous
surgical sterilization or lactating females) at screening.

15. Signed consent to long-term follow-up on protocol PA17-0483.

16. Disease-specific inclusion criteria

may be enrolled in the dose escalation phase. Patients must have received at least one
prior line of standard therapy.

18 Synovial Sarcoma (SS)

a. Patients must have a histologically confirmed diagnosis of synovial sarcoma with a
confirmation by the presence of a translocation between SYT on the X chromosome and SSX1,
SSX2 or, SSX4 on chromosome 18 (may be presented in the pathology report as t (X; 18)).

19. Myxoid/round cell liposarcoma (MRCLS)

a. Patients must have histologically confirmed myxoid/round cell liposarcoma with a

Exclusion Criteria:

1. Presence of clinically significant ≥ Grade 2 toxicity from previous anticancer
treatment, as determined by the PI.

Patients with previously treated brain metastases may participate provided they are
stable (without evidence of progression by imaging for at least 4 weeks prior to the

have no evidence of new or enlarging brain metastases, and are not using
corticosteroids for at least 7 days prior to trial treatment.

9. Patients must not have any other malignancies within the past 2 years except for in
situ carcinoma of any site, adequately treated (without recurrence post resection or
post radiotherapy) carcinoma of the cervix or basal or squamous cell carcinomas of the
skin, or active non-lifethreatening second malignancy that would not, in the
investigator's opinion, potentially interfere with the patient's ability to
participate and/or complete this trial. Examples include but are not limited to:
urothelial cancer Grade Ta or T1 and adenocarcinoma of the prostate treated by active
surveillance.

10. Presence of any other serious medical condition that may endanger the patient at

(e.g., stent, bypass)

- Severe aortic stenosis.

- Uncontrolled arrhythmia, considered per PI evaluation.

- Congenital long QT syndrome.

- Documentation, during the screening process, of a QTc > 470 milliseconds by
Fredericia criteria (QTcF) based on the average of 3 electrocardiograms (ECGs)
