DHEA in Synovial Sarcoma Patients

September 4, 2019 updated by: Washington University School of Medicine

A Phase I/II Clinical Trial of Dose-Escalating DHEA in Synovial Sarcoma Patients

DHEA is a natural allosteric inhibitor of glucose-6-phosphate dehydrogenase (G6PD). G6PD is a key regulatory enzyme for the survival of synovial sarcoma. The investigators postulate that they can inhibit the production of NADPH in synovial sarcoma and cause cell death by using a naturally occurring G6PD inhibitor.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Description

Inclusion Criteria:

  • Diagnosis of histologically or cytologically confirmed metastatic or non-resectable synovial sarcoma.
  • Failed at least one line of chemotherapy. Neoadjuvant and adjuvant chemotherapy count as a prior line of therapy.
  • Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm with CT scan, as ≥ 20 mm by chest x-ray, or ≥ 10 mm with calipers by clinical exam.
  • At least 16 years of age.
  • ECOG performance status ≤ 2

  • Normal bone marrow and organ function as defined below:

    • Leukocytes ≥ 3,000/mcL
    • Absolute neutrophil count ≥ 1,500/mcl
    • Platelets ≥ 50,000/mcl
    • Total bilirubin ≤ 1.5 x IULN
    • AST(SGOT)/ALT(SGPT) ≤ 3.0 x IULN
    • Creatinine ≤ IULN OR Creatinine clearance ≥ 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
  • Women of childbearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation. Patients using antiestrogens for oral birth control are ineligible. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately.
  • Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion Criteria:

  • A history of other malignancy ≤ 3 years previous with the exception of basal cell or squamous cell carcinoma of the skin which were treated with local resection only or carcinoma in situ of the cervix.
  • Currently receiving any other investigational agents.
  • Known brain metastases. Patients with known brain metastases must be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
  • A history of allergic reactions attributed to compounds of similar chemical or biologic composition to DHEA or other agents used in the study.
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.
  • Known HIV-positivity on combination antiretroviral therapy because of the potential for pharmacokinetic interactions with DHEA. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.
  • Known mania-associated psychiatric disorder.
  • Known seizure disorder.
  • Using corticosteroids or estrogen-based oral birth control.
  • Using drugs known to lower or increase levels of DHEA.
  • Requires estrogen or testosterone.
  • Taking warfarin sodium. Patients on other blood thinners should be monitored for thrombocytopenia.
  • Taking a strong inhibitor or inducer of cytochrome P450. Intermediate inhibitors are allowed if deemed medically necessary.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Maximum tolerated dose (MTD) of DHEA (Phase I only)
Time Frame: Completion of cycle 1 for all phase I patients (estimated to be 2 years)
  • MTD is defined as the dose level immediately below the dose level at which 2 patients of a cohort (of 2 to 6 patients) experience dose-limiting toxicity during the first cycle. Dose escalations will proceed until the MTD has been reached.

  • Dose-limiting toxicities are defined as one of the following events occurring during the 1st cycle of treatment thought to be possibly, probably, or definitely related to treatment:

    • Grade 3 or greater liver function test abnormalities
    • Grade 3 or greater psychiatric disorder
    • Quality of life (QOL) alteration (change in score of 30%)
Completion of cycle 1 for all phase I patients (estimated to be 2 years)
Progression-free rate (complete response + partial response + stable disease) (Phase II only)
Time Frame: Up to 5 years
  • Complete response (CR): disappearance of all target lesions, any pathological lymph nodes (whether target or non-target) must have reduction inf short axis to <10mm, disappearance of all non-target lesions and normalization of tumor marker level.
  • Partial response (PR): at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
  • Stable disease (SD): neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease, taking as reference the smallest sum diaters while on study
Up to 5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Rate of progression-free survival (PFS) (Phase II only)
Time Frame: 3 months
  • PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first.
  • Progressive disease (PD): aAppearance of one or more new lesions and/or unequivocal progression of existing non-target lesions. Unequivocal progression should not normally trump target lesion status. It must be representative of overall disease status change, not a single lesion increase.
3 months
Toxicity of DHEA as measured by grade and frequency of adverse events
Time Frame: 30 days after completion of treatment (estimated to be 7 months)
-The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all toxicity reporting.
30 days after completion of treatment (estimated to be 7 months)
