Retreatment With CTL019/CTL119

Phase 1

Not yet recruiting

• Conditions: Lymphoma, B-Cell
• Interventions: Drug: CD19 redirected autologous T cells (CTL019 or CTL119 cells)

• Registration Number: NCT04419909
• Lead Sponsor: University of Pennsylvania

Brief Summary

This research study is designed to evaluate the effects of retreatment with CTL019/CTL119 in patients with late relapse of B-cell lymphomas.

Detailed Description

This is a single arm open label trial that will assess the safety and efficacy of retreatment with CTL019/CTL119 chimeric antigen receptor (CAR) modified T cells in patients who have late relapse of diffuse large B-cell or follicular lymphoma after achieving complete remission from prior CTL019/CTL119 treatment. Patients eligible for this protocol will have been treated initially with CTL019/CTL119 under UPCC13413/NCT02030834, have experienced a durable complete response (defined as ≥ 6 months duration), and have a residual manufactured CTL019/CTL119 product available. This protocol will serve subjects with no available potentially curative treatment options (such as autologous or allogeneic stem cell transplantation) who have a limited prognosis (months to \< 2 year expected survival) with available therapies.
