A Pilot Study of Genetically Engineered NY-ESO-1 Specific NY-ESO-1ᶜ²⁵⁹T in HLA-A2+ Patients With Synovial Sarcoma

Completed · Phase 1

Conditions studied: Neoplasms

In brief

The purpose of this early (pilot) clinical trial is to test the effects (both good and bad) of chemotherapy and adoptive immunotherapy with T cells engineered to recognize NY-ESO-1 peptide in patients with unresectable, metastatic or recurrent synovial sarcoma.

You may qualify if…

• Synovial sarcoma that has been treated with standard chemotherapy containing ifosfamide and/or doxorubicin and remains: unresectable or metastatic or progressive/persistent or recurrent disease
• Measurable disease
• Patients must have proven positive tumor sample for NY-ESO-1 as follows:
• Cohort 1 -Positive expression is defined as 2+ and/or 3+ by immunohistochemistry in ≥ 50% of cells.
• Cohort 2 -Positive expression is defined as ≥1+ by immunohistochemistry in ≥1% cells, but not to exceed 2+ and/or 3+ in ≥ 50% of cells.
• Cohort 3 -Positive expression is defined as 2+ and/or 3+ by immunohistochemistry in ≥ 50% of cells.
• Cohort 4 -Positive expression is defined as 2+ and/or 3+ by immunohistochemistry in ≥ 50% of cells.
• HLA-A*02:01, HLA-A*02:05, and/or HLA-A*02:06 by high resolution testing at a local or central laboratory
• Weigh more than 18 kg
• All previous cytotoxic chemotherapy, monoclonal antibody therapy, or immune therapy must be washed out 3 weeks before apheresis and must be completed at least 3 weeks prior to pre-infusion lymphodepletive chemotherapy.
• Systemic corticosteroid or other immunosuppressive therapy should be washed out 2 weeks before apheresis and must be completed at least 2 weeks prior to pre-infusion lymphodepletive chemotherapy.
• Biologic or other approved molecular targeted small molecule inhibitors should be washed out 1 week or 5 half-lives (whichever is longer) before apheresis and must be completed at least 1 week or 5 half-lives (whichever is longer) prior to pre-infusion lymphodepletive chemotherapy.
• Any grade 3 or 4 hematologic toxicity of any previous therapy must have resolved to grade 2 or less prior to apheresis and any grade 3 or 4 toxicity must have resolved to grade 2 or less prior to pre-infusion lymphodepletive chemotherapy.
• ECOG 0-1, or for children ≤10 years of age, Lansky > 60
• Life expectancy > 3 months
• Left ventricular ejection fraction ≥ 40% or fractional shortening ≥ 28%
• T. bilirubin < 2 mg/dl (Patients with Gilbert Syndrome total bilirubin <3xULN and direct bilirubin ≤ 35%)
• AST, ALT ≤ 2.5 x upper limit of normal
• ANC ≥ 1.0 x 10⁹/L
• Platelets ≥ 75 x 10⁹/L
• Age-adjusted normal serum creatinine or a creatinine clearance ≥ 40 ml/min
• Ability to give informed consent for patients greater than 18 years of age. For patients less than 18 years of age the legal guardian must give informed consent.
• Male patients must be willing to practice birth control (including abstinence) during and for 4 months after treatment. Female patients must be willing to practice birth control (including abstinence) during treatment and for 4 months after gene modified cells are no longer detected in body.

You may not qualify if…

• Active HIV, HBV, HCV or HTLV 1/2 infection (due to increased risk of complications during lymphodepleting regimen and confounding effects on the immune system). Active hepatitis B or C infection is defined by seropositive for hepatitis B surface antigen (HbSAg) or hepatitis C antibody.
