Inclusion Criteria:
1. Able to understand and sign the consent. For patients <18yo, consent by a parent or
guardian and appropriate assent by the patient will be obtained.
2. Patients must be age = 2 years.
3. Karnofsky performance status ( > 60). For children and adolescent patients, Lansky
performance status should be performed and converted to Karnofsky performance status
utilizing the conversion table in Appendix IV: Performance Status Conversion Chart.
4. Presence of measurable disease per RECIST v1.1.
5. The phase I portion of the study (dose finding portion) will include patients with
relapsed or refractory clear cell sarcoma and other fusion positive relapsed or
refractory sarcomas as documented by official pathology report from the diagnosing
institution or commercial laboratory.
Patients with Ewing Sarcoma (EWS) can also be enrolled in the phase I portion of the
study only. Patients in the phase 1 portion of the study with EWS will have progressed
after at least one prior-line of standard therapy and patients with TRK
fusion-positive tumors will have received prior therapy with a TRK inhibitor. Patients
must have relapsed or refractory clear cell sarcoma for the phase II portion of the
study, defined as a recurrence of disease following or having failed to achieve a
response to at least one prior therapy. Diagnosis of clear cell sarcoma must be
documented by official pathology report from the diagnosing institution or commercial
laboratory including presence of a characteristic translocation such as
t(12;22)(q13;q12).
6. Fertile men and their partners who are female of reproductive potential, must agree to
abstain from sexual intercourse or to use two highly effective forms of contraception
from the time of giving informed consent, during the treatment and for 180 days
(females and males) following the last dose of devimistat. A highly effective form of
contraception is defined as hormonal oral contraceptives, injectables, patches,
intrauterine devices, doublebarrier method (e.g., synthetic condoms, diaphragm, or
cervical cap with spermicidal foam, cream, or gel), or male partner sterilization.
7. Organ Function Requirements:
Adequate bone marrow function defined as:
1. For patients with solid tumors without known bone marrow involvement:
• Peripheral absolute neutrophil count (ANC) = 1,000/mm3
• Platelet count = 100,000/mm3 (transfusion independent, defined as not receiving
platelet transfusions for at least 7 days prior to enrollment)
Adequate Renal Function Defined as:
• Creatinine clearance or radioisotope GFR = 60mL/min/1.73 m2 or
• A serum creatinine based on age/gender as follows:
Age Maximum Serum Creatinine (mg/dL) Male Female 2 to < 6 years 0.8 0.8 6 to < 10
years 1.0 1.0 10 to < 13 years 1.2 1.2 13 to < 16 years 1.5 1.4
= 16 years 1.7 1.4 The threshold creatinine values in this Table were derived from the
Schwartz formula for estimating GFR utilizing child length and stature data published
by the CDC.
Adequate Liver function is defined as:
• Bilirubin (sum of conjugated + unconjugated) = 1.5 x upper limit of normal (ULN) for
age
• SGPT (ALT) =2.5 times the ULN
- SGOT (AST) =2.5 times the ULN
- Serum albumin = 2 g/dL
Adequate Neurologic function is defined as:
• Patients with seizure disorder may be enrolled if on anticonvulsants and well
controlled.
Adequate Blood Pressure.
Exclusion Criteria:
1. Have received other chemotherapy within 14 days of initiation of study therapy or
immunotherapy (antibody based) within 28 days of initiation of study therapy.
2. For whom potentially curative anticancer therapy is available.
3. Are pregnant or breast feeding.
4. Have known hypersensitivity to any of the components of devimistat or
hydroxychloroquine.
5. Have any other medical or psychological condition, deemed by the physician to be
likely to interfere with a subject's ability to sign informed consent, cooperate,
or participate in the treatment.
6. Patients who have an uncontrolled infection are not eligible.
7. Patients with known G6PD deficiency.
8. Patients with known underlying retinal disease.
9. Have immediately life-threatening, severe complications of malignancy such as
uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated
intravascular coagulation.
10. Are unable to take oral medication OR have malabsorption syndrome or any other
uncontrolled gastrointestinal condition (eg, nausea, diarrhea, vomiting) that
might impair the bioavailability of study treatment.
11. Use of high-risk QT-prolonging drugs and patients with a history of torsades de
pointes.
12. Unresolved toxicity from prior therapy that has failed to resolve to CTCAE =
grade 1 or baseline toxicity with the exception of alopecia
13. History of unstable or deteriorating cardiovascular disease within the previous 6
months prior to screening including but not limited to the following: unstable
angina or myocardial infarction, CVA/stroke, Congestive heart failure (New York
Heart Association [NYHA] Class III or IV, or uncontrolled clinically significant
arrhythmias.
14. Marked baseline prolongation of QT/QTc interval (repeated exhibition of a QTc
interval >480 ms for both male and female patients)
15. Unwilling or unable to avoid the concomitant use of strong CYP3A4 inducers or
inhibitors during study treatment.
16. Patients concomitantly on tamoxifen are excluded due to increased ocular toxicity
with hydroxychloroquine
