Genetically Engineered Cells (ATLCAR.CD30) for the Treatment of Patients with Refractory or Relapsed CD30+ Nonseminomatous Germ Cell Tumors
This phase II trial tests how well autologous CD30CAR-CD28-CD3zeta-expressing T-lymphocytes (ATLCAR.CD30) works in treating patients with nonseminomatous germ cell tumors that do not respond to treatment (refractory) or that have come back after a period of improvement (relapsed/recurrent). Chimeric antigen receptor (CAR) T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient’s blood. Then the gene for a special receptor that binds to a certain protein on the patient’s cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. ATLCAR.CD30 cells may be effective at treating patients with refractory or relapsed nonseminomatous germ cell tumors.
Inclusion Criteria
- Written informed consent and Health Insurance Portability and Accountability Act (HIPAA) authorization for release of personal health information explained to, understood by, and signed by the subject or legally authorized representative.
- Age >= 18 years at the time of consent.
- Histological confirmed diagnosis of NSGCT of any primary site.
- Subjects must have received at least one prior lines of therapy for their NSGCT and meet one of the following criteria. There is not a maximum number of prior lines of treatment allowed. * Evidence of progressive or recurrent NSGCT after prior high dose chemotherapy (HDCT) treatment, defined as meeting at least one of the following criteria: ** Tumor biopsy of new or growing or unresectable lesions demonstrating viable NSGCT. In the event of an incomplete gross resection where viable NSGCT is found, subjects will be considered eligible for the study. ** Consecutive elevated serum tumor markers (beta human chorionic gonadotropin [beta-HCG] or alpha-fetoprotein [AFP]) that are increasing. Increase of an elevated lactate dehydrogenase (LDH) alone does not constitute progressive disease. ** Development of new or enlarging lesions in the setting of persistently elevated beta-HCG or AFP, even if the beta-HCG and AFP are not continuing to rise. * Subjects deemed not to be a candidate for or benefit from potentially curative HDCT or other curative treatment options defined as follows: ** Subjects with inadequate renal function for HDCT. ** Subjects who have had 3 or more lines of prior chemotherapy as this patient population has historically not benefited from HDCT. ** Subjects with late relapse (relapse > 2 years after last therapy) as this patient population has historically not benefited from HDCT. ** Subject with inadequate stem cell collection to move forward with HDCT. ** Subjects with significant medical or psychosocial comorbidities that are felt to be a contraindication to HDCT by the treating investigator. NOTE: Subjects with clinically growing “teratoma” (normal declining tumor markers and radiographic or clinical progression) should be considered for surgery. In subjects with rising tumor markers as their only evidence of disease progression where AFP is < 30 or beta-HCG is < 15, alternate causes of increased levels of these marks should be ruled out (e.g., hypogonadism by testosterone suppression of luteinizing hormone [LH], hepatitis, use of marijuana).
- Histologically confirmed diagnosis of NSGCT of any primary site expressing CD30. NOTE: CD30+ disease requires documented CD30 expression by immunohistochemistry based on the institutional hematopathology standard. This analysis will occur centrally at the University of North Carolina (UNC) site.
- Subject has available archival tissue for evaluation of CD30 expression OR is willing to undergo a mandatory biopsy to access expression. Subject must also be willing to undergo a pre-infusion (if one was not previously collected prior to procurement) and progression biopsy unless the tumor site is not easily accessible and there is more than minimal risk associated with obtaining the biopsy.
