Outcome Measures
Primary Outcome Measures
- Safety of TIL therapy in Pediatric Solid Tumors [3 years]
The regimen will be declared safe if <33% of patients (0 or 1 out of maximum 6 patients on the safety phase) experience a dose-limiting toxicity (DLT).
Secondary Outcome Measures
- Feasibility of Generating TIL Product from Pediatric Solid Tumors [3 years]
The TIL acquisition/production strategies will be considered feasible if 50% or more of all tumors collected on the prospective biobanking study generate a primary TIL culture that is satisfactory for rapid expansion for use on the Phase I trial.
- Toxicity of TIL Therapy in Pediatric Solid Tumors [3 years]
Toxicities of all grades related to therapy and all Grade 3 and higher toxicities will be collected.
- Disease Response to TIL Therapy [3 years]
For recurrent patients with measurable disease, Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 will be used. For all patients, event-free survival (EFS) will be reported.
Eligibility Criteria
Criteria
INCLUSION CRITERIA
Part One (Prospective biobanking study):
-
Patients must be ≥1 year to ≤ 21 years of age at time of enrollment to Part One.
-
Initial therapy patients: Patients with a histologic diagnosis of high-risk pediatric malignant solid tumors (pMST), defined as a pediatric malignant solid tumor outside of the central nervous system, newly-diagnosed or being treated with initial therapy, with expected 5-year Event-Free Survival (EFS) <60%. Examples include:
-
High-risk neuroblastoma
-
Metastatic Ewing sarcoma
-
Metastatic osteosarcoma
-
Hepatoblastoma metastatic or not amenable to total resection
-
Desmoplastic small round cell tumor
-
Metastatic rhabdomyosarcoma
-
Metastatic non-rhabdomyosarcoma soft tissue sarcomas (NRSTS)
-
Metastatic diffuse anaplastic Wilms tumor
-
Malignant rhabdoid tumor of kidney or liver
-
Mediastinal mixed germ cell tumors
-
Other tumors may be deemed eligible after assessment and documentation of prognosis from an enrolling institution's multidisciplinary tumor board.
-
Note: There will be occasions prior to establishment of a histologic diagnosis where an investigator will highly suspect one of the diagnoses above in a patient due to undergo a surgical procedure (initial biopsy, up-front resection, etc.). If this is the case, the investigator may choose to enroll the patient prior to a tissue diagnosis. Their suspicion of a qualifying diagnosis should be documented. If the diagnosis is confirmed, the patient may continue on study. If the diagnosis is not confirmed, the patient will be considered a screening failure and removed from study.
-
Relapsed/refractory/recurrent patients: patients must have a histologic diagnosis of pMST (may include diagnoses outside those identified in Part 1) that has relapsed after achieving remission or progressed after completion of all planned initial therapy.
-
Patients must have an open surgical biopsy or resection planned (core needle/final needle biopsies are not allowed) for standard of care purposes, at some point in their initial or relapsed therapy for pMST.
Note: The surgery for tissue procurement may occur at any time during initial therapy including up-front surgeries or after neoadjuvant therapies, including chemotherapy, immunotherapy, and radiation.
• All patients and/or their parents or legal guardians must have the ability to understand and the willingness to sign a written informed consent or assent document.
Part Two: Phase I Clinical Trial

- Relapsed/refractory disease: Patients with a histologic diagnosis of high-risk pMST as defined in Part 1 inclusion who have recurrent/refractory local or metastatic disease that is either measurable or evaluable by RECIST 1.1 51
OR:
- Adjuvant therapy for poor prognosis tumors: patients qualifying for TIL collection as per Part 1, deemed by the treating investigator to have <30% chance at long-term cure who has reached the end of their primary therapy with a disease status of Stable Disease or better and who have achieved appropriate washout period. Measurable or evaluable disease per RECIST 1.1 is NOT required for these patients.
