Обзор
The study participant has one of the following blood cancers: acute myelogenous leukemia (AML)/myelodysplastic syndrome (MDS), acute lymphoblastic leukemia (B-ALL, T-ALL) or Lymphoma. Your cancer has been difficult to treat (refractory) or has come back after treatment (relapse). Primary Objective To determine the safety and maximum tolerated dose of intravenous infusions of escalating doses of CD70-CAR T cells in patients (≤21 years) with recurrent/refractory CD70+ hematological malignancies after lymphodepleting chemotherapy. Secondary Objectives To evaluate the antileukemic activity of CD70-CAR T cells. We will determine the anti- leukemic activity of the CD70-CAR T cells in the bone marrow and in the treatment of extramedullary disease.
Подробное описание
The primary interventions are a lymphodepleting chemotherapy regimen (fludarabine and cyclophosphamide), followed by a single autologous infusion of CD70-CAR T cells.
Phase I study evaluating three (3) dose levels of CD70-CAR T cells.
Вмешательства
- Препарат Fludarabine
40mg/m2, Day -4, -3 and -2 - Препарат Cyclophosphamide
Day -3 and Day-2 REST DAY, -1 - Препарат CD70-CAR T cell infusion (Autologous)
Day 0 or +1 - Препарат Mesna
Mesna is generally dosed at approximately 25% of the cyclophosphamide dose. It is generally given intravenously prior to and again at 3, 6 and 9 hours following each dose of cyclophosphamide
Первичные конечные точки
- Maximum tolerated dose of CD70-CAR T cells [Срок оценки: 28 days after CD70-CAR T-cell infusion]

- Relapsed/refractory CD70+ AML or MDS:
- Relapsed disease that is CD70 positive
- Refractory disease that is persistent despite 3 cycles of chemotherapy
- Relapsed/refractory CD70+ B-cell ALL:
- Relapsed disease that is CD70 positive and CD19 negative/dim or patients otherwise ineligible for CD19-directed therapies including:
- Patients in 2nd or greater relapse

Karnofsky or Lansky (age- dependent) performance score ≥50
Patients with a history of prior allogeneic HCT must be clinically recovered from prior HCT therapy, have no evidence of active GVHD and have not received a donor lymphocyte infusion (DLI) within the 28 days prior to apheresis
Patient must have an identified HCT donor
For females of childbearing age:
i. Not lactating with intent to breastfeed
ii. Not pregnant with negative serum or urine pregnancy test within 7 days prior to enrollment
