简要总结

First-in-human, open-label, dose-finding and dose-expansion study of UCART20x22 administered intravenously in subjects with relapsed or refractory B-Cell Non-Hodgkin Lymphoma (B-NHL). The purpose of this study is to evaluate the safety and clinical activity of UCART20x22 and determine the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D).

入选标准

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
  • Relapsed or refractory (R/R) mature B-NHL per 2016 WHO criteria and positive for CD20 and/or CD22
  • Subjects with NHL subtypes defined by WHO:
  • Dose-Finding Part: R/R mature B-NHL (except chronic lymphocytic leukemia/small lymphocytic leukemia [CLL/SLL], Richter's transformation from prior CLL/SLL, Burkitt's lymphoma, and Waldenstrom's macroglobulinemia)
  • Dose-Expansion Part: R/R LBCL, defined as:
  • i. DLBCL; ii. High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements; iii. Transformed FL or transformed marginal zone lymphoma (MZL); iv. Follicular lymphoma Grade 3B
  • R/R disease after at least 2 lines of prior treatment, which must have included:
  • An Anti-CD20 MoAb and an anthracycline for DLBCL, high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements, primary mediastinal large B-cell lymphoma (PMBCL), or transformed FL or MZL
  • An alkylating agent in combination with an anti-CD20 MoAb for FL
  • An anthracycline or bendamustine-containing chemotherapy regimen and a Bruton's tyrosine kinase (BTK) inhibitor for mantle cell lymphoma (MCL)
  • Autologous anti-CD19 CAR T-cell therapy, if approved and available for the indicated lymphoma subtype, unless the subject is unable or is ineligible to receive approved autologous anti-CD19 CAR T-cell therapy (e.g., fail leukapheresis or manufacture, unable to wait for manufacture, CD19 negative disease, etc.)
  • Autologous hematopoietic stem cells must be available prior to the start of the LD regimen if the subject is considered high-risk for prolonged hematologic toxicity.

排除标准

  • Prior use of an investigational product (except for cell or gene therapies and MoAbs) within 5 half-lives or within 14 days, whichever is shorter, prior to start of LD regimen
  • Previous approved therapy including chemotherapy, biologic (except MoAbs), or targeted therapy for R/R B-NHL with 5 half-lives or within 14 days, whichever is shorter, prior to start of the LD regimen
  • > 4 lines of therapy R/R B-NHL prior to start of the LD regimen.
  • Prior MoAb therapy (approved or investigational) within 30 days prior to start of LD
  • Prior systemic immunostimulatory agent within 3 half-lives prior to start of the LD regimen
  • Prior cell or gene therapy (approved or investigational) within 6 months of the start of LD
  • Prior cell or gene therapy (approved or investigational) targeting both CD20 and CD22
  • Autologous HSCT infusion within 6 weeks of the start of LD
  • Allogeneic HSCT within 3 months of the start of LD, or donor lymphocyte infusion within 6 weeks of the start of LD
  • Active acute or chronic graft versus host disease (GvHD). Subjects should be off all immunosuppressive therapies for at least 6 weeks prior to start of LD
  • Radiotherapy within 8 weeks (except for palliative radiotherapy for specific on-target lesions) (prior to start of LD regimen)
  • Evidence of active central nervous system (CNS) lymphoma or previous CNS involvement of R/R B-NHL
  • Presence of an active and clinically relevant CNS disorder
  • Daily treatment with >20 mg prednisone or equivalent
  • Known active infection, or reactivation of a latent infection, whether bacterial or viral, fungal, mycobacterial, or other pathogens
  • History of hypersensitivity to alemtuzumab
  • History of neutralizing anti-drug antibody against alemtuzumab
  • Any known uncontrolled cardiovascular disease within 3 months of enrollment
  • Subjects requiring immunosuppressive treatment
  • Major surgery within 28 days prior to start of LD
  • Evidence of another uncontrolled malignancy within 2 years prior to Screening (except in situ nonmelanoma skin cell cancers and/or carcinoma in-situ of the cervix)
