Trial Summary

What is the purpose of this trial?

Patients with high-risk solid tumors, those that are refractory to standard up front therapy or relapse after completion of therapy, have a very poor prognosis despite attempts to induce remission with salvage regimen. Novel therapies are critical for this patient population with high-risk cancer. The ability of tumors to be recognized and lysed by the immune system offers a unique opportunity to aid in tumor eradication by expanding and activating these anti-tumor cells. Through this ability to harness sophisticated and specific immunotherapy, residual or relapsed disease that is resistant to chemotherapy and/or radiotherapy could be eradicated. Prior studies have suggested both safety of expanded specific T cells and efficacy in the setting of melanoma, lymphoma or viral eradication. While this therapy has previously been limited by the versatility of the tumor to down-regulate antigens and evade a single immune-target, the use of multi-antigen specific T cells may permit better and more durable anti-tumor immunity. Thus, the investigators propose to infuse these specific multi-antigen anti-tumor T lymphocytes into patients with high risk solid tumors. This trial will be conducted to demonstrate safety of these cells and generate efficacy and biology data that may be important for future studies that may enhance tumor immunotherapy.

Eligibility Criteria

This trial is for people aged 6 months to 60 years with high-risk solid tumors like Ewing sarcoma or adenocarcinoma, who have either not responded to standard treatments or whose cancer has returned. Participants need a minimum level of immune cells and organ function, must not be pregnant or breastfeeding, agree to use contraception if applicable, and cannot have uncontrolled infections or recent immunotherapy.

Treatment Details

Interventions

  • Tumor associated antigen lymphocytes (TAA-CTL) (CAR T-cell Therapy)
Trial OverviewThe study tests the safety and potential effectiveness of TAA-CTLs—immune cells trained to target multiple tumor-associated antigens—in patients with tough-to-treat solid tumors. The goal is to see if these specialized T cells can help fight off cancers that haven't responded well to other treatments.
Participant Groups
2Treatment groups
Experimental Treatment
Group I: Group BExperimental Treatment1 Intervention
Group B includes patients who have undergone conventional (standard) therapy which does not include an allogeneic HSCT. Within group B, a cohort of patients with relapsed or refractory Wilms tumor will be enrolled and receive a lymphodepleting chemotherapy regimen followed by TAA-T. Group B patients (no prior allogeneic HSCT): TAA-T will be infused any time \>1 week after completing most recent course of conventional (non-investigational) therapy for their disease. Patients receiving lymphodepletion will be \>2 weeks from most recent course of conventional therapy and have nadired and recovered before beginning protocol therapy.
Group II: Group AExperimental Treatment1 Intervention
Group A includes patients who have undergone an allogeneic hematopoietic stem cell transplant (HSCT) as part of their prior therapy. Group A patients (post allogeneic HSCT): TAA-T will be infused any time after neutrophil engraftment post-HSCT or day 30, whichever comes first.
