Study Details

Study Description

Brief Summary

To determine the safety, efficacy and optimal cell dose of CAR 5/IL15-transduced CB-NK cells in patients with relapsed/refractory T-cell malignances, mantle cell lymphoma, and chronic lymphocytic leukemia. The efficacy and optimal dose will be identified for individual diseases.

Condition or Disease Intervention/Treatment Phase
Phase 1/Phase 2

Detailed Description

Primary objective:

To determine the safety, efficacy and optimal cell dose of CAR.5/IL15-transduced CB-NK cells in patients with relapsed/refractory T-cell malignances, mantle cell lymphoma, and chronic lymphocytic leukemia. The efficacy and optimal dose will be identified for individual diseases.

Secondary Objectives:
  • To assess the overall response rate (complete and partial response rates)

  • To quantify persistence of infused allogeneic donor CAR-transduced CB-derived NK cells in -To conduct comprehensive immune reconstitution studies.

    Outcome Measures

    Primary Outcome Measures

    1. Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE Version 5.0. [through study completion, an average of 1 year]

      General grading: Grade 1: Mild: discomfort present with no disruption of daily activity, no treatment required beyond prophylaxis. Grade 2: Moderate: discomfort present with some disruption of daily activity, require treatment. Grade 3: Severe: discomfort that interrupts normal daily activity, not responding to first line treatment. Grade 4: Life Threatening: discomfort that represents immediate risk of death
