NCT04432649

Brief Summary

Patients with refractory and/or recurrent solid tumor have poor prognosis despite complex multimodel therapy and therefore, novel approaches are urgently needed. This study attempts to treat these diseases using T cells genetically modified with a 4th generation lentiviral chimeric antigen receptor (4SCAR fused with an inducible apoptotic caspase 9 domain) targeting CD276 (B7-H3). The 4SCAR-CD276-modified T cells (4SCAR-276) can recognize and kill tumor cells through the recognition of CD276, a surface protein expressed at high levels on many types of tumors but at low levels on normal tissues. This study will evaluate the side effects and effective doses of 4SCAR-276 in treating refractory and/or recurrent tumors.

Eligibility Criteria

Age1 Year - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with tumors have received standard first-line therapy and have been judged to be non-resectable, metastatic, progressive or recurrent.
  • The CD276 antigen status of the tumor is determined for eligibility. Positive expression is defined by antibody staining results based on immunohistochemistry or flow cytometry analysis.
  • Body weight greater than or equal to 10 kg.
  • Age: ≥1 year and ≤ 75 years of age at the time of enrollment.
  • Life expectancy: at least 8 weeks.
  • Prior Therapy: 1) There is no limit to the number of prior treatment regimens. Any grade 3 or 4 non-hematologic toxicity of any previous therapy must have resolved to grade 2 or less. 2) Must not have received hematopoietic growth factors for at least 1 week prior to mononuclear cells collection. 3) At least 7 days must have elapsed since the completion of therapy with a biologic agent, targeted agent, tyrosine kinase inhibitor or a metronomic nonmyelosuppressive regimen. 4) At least 4 weeks must have elapsed since prior therapy that included a monoclonal antibody. 5) At least 1 week since any radiation therapy at the time of study entry.
  • Karnofsky/jansky score of 60% or greater.
  • Cardiac function: Left ventricular ejection fraction greater than or equal to 40/55 percent .
  • Pulse Ox greater than or equal to 90% on room air.
  • Liver function: defined as alanine transaminase (ALT) \<3x upper limit of normal (ULN), aspartate aminotransferase (AST) \<3x ULN; serum bilirubin and alkaline phosphatase \<2x ULN.
  • Renal function: Patients must have serum creatinine less than 3 times upper limit of normal.
  • Marrow function: White blood cell count ≥1000/ul, Absolute neutrophil count ≥500/ul, Absolute lymphocyte count ≥500/ul, Platelet count ≥25,000/ul (not achieved by transfusion).
  • Patients with known bone marrow metastatic disease will be eligible for study as long as they meet hematologic function criteria, and the marrow disease not evaluable to have hematologic toxicity.
  • For all patients enrolled in this study, themselves or their parents or legal guardians must sign an informed consent and assent.

You may not qualify if:

  • Existing severe illness (e.g. significant cardiac, pulmonary, hepatic diseases, etc.) or major organ dysfunction, or grade 3 hematologic toxicity.
  • Untreated central nervous system (CNS) metastasis: Patients with CNS tumor involvement that has been treated and/or is stable for at least 6 weeks following completion of therapy are eligible.
  • Previous treatment with other genetically engineered CD276-CAR T cells or CD276 antibody therapy.
  • Active HIV, Hepatitis B virus (HBV), Hepatitis C virus (HCV) infection or uncontrolled infection.
  • Patients who require systemic corticosteroid or other immunosuppressive therapy.
  • Evidence of tumor potentially causing airway obstruction.
  • Inability to comply with protocol requirements.
  • Insufficient CAR T cells availability.
