To Evaluate Maximally Tolerated Dose (MTD), Safety and Efficacy of CPI-613® (Devimistat) Plus Hydroxychloroquine in Patients With Relapsed or Refractory Clear Cell Sarcoma of Soft Tissue

Completed · Phase 1/Phase 2

Conditions studied: Sarcoma, Clear Cell

In brief

The goal of this trial in Phase I is to determine the maximally tolerated dose (MTD) of hydroxychloroquine in combination with devimistat in patients with relapsed or refractory Clear Cell Sarcomas of the Soft Tissue and to describe the full toxicity profile. In Phase II, the goal is to evaluate the response rate \[Complete Rate (CR) + Partial Rate (PR)\] of the combination of devimistat and hydroxychloroquine in patients with relapse or refractory Clear Cell Sarcoma of the Soft Tissue and to evaluate the PK and PK/PD profiles for efficacy and safety of the combination of devimistat and hydroxychloroquine.

Who can join

Age: 2 and older, up to 100. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

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.
Patients must be age ≥ 2 years.
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.
Presence of measurable disease per RECIST v1.1.
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).
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.
Organ Function Requirements:
Adequate bone marrow function defined as:
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.

You may not qualify if…

Have received other chemotherapy within 14 days of initiation of study therapy or immunotherapy (antibody based) within 28 days of initiation of study therapy.
For whom potentially curative anticancer therapy is available.
Are pregnant or breast feeding.
Have known hypersensitivity to any of the components of devimistat or hydroxychloroquine.
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.
Patients who have an uncontrolled infection are not eligible.
Patients with known G6PD deficiency.
Patients with known underlying retinal disease.
Have immediately life-threatening, severe complications of malignancy such as uncontrolled bleeding, pneumonia with hypoxia or shock, and/or disseminated intravascular coagulation.
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.
Use of high-risk QT-prolonging drugs and patients with a history of torsades de pointes.
Unresolved toxicity from prior therapy that has failed to resolve to CTCAE ≤ grade 1 or baseline toxicity with the exception of alopecia
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.
Marked baseline prolongation of QT/QTc interval (repeated exhibition of a QTc interval >480 ms for both male and female patients)
Unwilling or unable to avoid the concomitant use of strong CYP3A4 inducers or inhibitors during study treatment.
Patients concomitantly on tamoxifen are excluded due to increased ocular toxicity with hydroxychloroquine
