Details and patient eligibility

About

This is an open-label, Phase I study of QN-019a (allogeneic CAR-NK cells targeting CD19) as monotherapy in relapsed/refractory B-cell Acute Lymphoblastic Leukemia (B-ALL) and in combination with Rituximab in relapsed/refractory B-cell Lymphoma.

This clinical study is to evaluate the safety, tolerability and preliminary efficacy of QN-019a in patients with relapsed/refractory B-cell lymphoma or B-ALL. Up to 22-36 patients will be enrolled.

Full description

This is an open-label, Phase I study of QN-019a (allogeneic CAR-NK cells targeting CD19) as monotherapy in relapsed/refractory B-cell Acute Lymphoblastic Leukemia (B-ALL) and in combination with Rituximab in relapsed/refractory B-cell Lymphoma.

This clinical study is to evaluate the safety, tolerability and preliminary efficacy of QN-019a in patients with relapsed/refractory B-cell lymphoma or B-ALL, where a "3+3" enrollment schema will be utilized at dose escalation stage. Up to 24-36 patients will be enrolled.

Key Inclusion Criteria:

  • Diagnosis of B-cell lymphoma or B-ALL as described below:

B-cell Lymphoma:

  • Histologically documented lymphomas expected to express CD19 and CD20
  • Relapsed/refractory disease following at least two prior systemic treatment regimens, or relapsed after the autologous hematopoietic stem cell transplantation (HSCT)

B-ALL:

  • Diagnosis of B-ALL that expected to express CD19
  • Relapsed/refractory disease following prior systemic treatment regimens

ALL SUBJECTS:

  • Provision of signed and dated informed consent form (ICF)
  • Age ≥ 18 years old
  • Stated willingness to comply with study procedures and duration
