Phase 1/2 Study of CD19 Chimeric Antigen Receptor T-cell (CD19 CAR-T; PL001) for Relapsed or Refractory B-cell Lymphoma
A Phase 1/2 Multicenter, Open-label, Single-arm Study to Evaluate the Safety and Efficacy of CD19-targeted Chimeric Antigen Receptor T-cell (CD19 CAR-T; PL001) Therapy in Patients With Relapsed or Refractory B-cell Lymphoma

Brief Summary
This is a multiple center, non-randomized, open-label, phase 1/2 study. The primary objective of Phase 1 is to evaluate the safety of PL001 and find the recommended Phase 2 dose (RP2D). The objective of Phase 2 is to evaluate the safety and efficacy of CD19 CAR-T(known as PL001).

Study Arms (1)
CD19-targeted chimeric antigen receptor T-cell
EXPERIMENTALPatients will receive a lymphodepletion chemotherapy with fludarabine plus cyclophosphamide for three consecutive days(Day -5 to Day -3) before infusion of CD19-targeted chimeric antigen receptor T-cell (CD19 CAR-T). Patients will receive the CD19 CAR-T(also known as PL001) infusion on Day 0.
Interventions
Drug: Fludarabine patients will receive a lymphodepletion chemotherapy with Fludarabine 25 mg/m2/day IV for 3 days on Day-5 to Day-3(a safe window for a small subset of patients will be D -7 to D -3). Drug: Cyclophosphamide patients will receive a lymphodepletion chemotherapy with cyclophosphamide 300 mg/m2/day IV for 3 dys Day-5 to Day-3(a safe window for a small subset of patients will be D -7 to D -3). Biological: CD19 CAR-T CD19 CAR-T cells will be administered using as a single dose at 0.1-9\*10\^6 cells/kg on Day 0 after completion of the lymphodepletion chemotherapy. The body weight calculated for PL001 dose is the actual body weight on the day of leukapheresis.
Eligibility Criteria
You may qualify if:
- Screening 1:
- Patient is ≥14 years of age, inclusive, at the time of signing the informed consent.
- Histologically confirmed diagnosis of diffuse large B-cell lymphoma (DLBCL), primary mediastinal large B-cell lymphoma (PMLBCL), large B-cell lymphoma transformed from follicular lymphoma (FL), or grade 3a or 3b FL.
- On-site documentation of CD19 on the dominant population of cancer cells.
- Disease status should meet any one of the below:
- Patients with previous autologous-hematopoietic stem cell transplantation (auto HSCT) have relapsed, progressive, or refractory disease (defined as having not achieved a CR) after transplantation regardless of lines of systemic therapy.
- Patients without previous HSCT have relapsed, progressive, or refractory disease (defined as having not achieved a CR) after at least 2 lines of systemic therapy, including anti-CD20 antibody and anthracycline.
- Have no available effective systemic therapy as judged by the Investigator.
- At least one measurable non-CNS (central nervous system) lesion based on Lugano classification for lymphoma.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2.
- Life expectancy of at least 3 months.
- Patient is male or female.
- A male patient must agree to use a highly effective contraception as detailed in Section 10.4 (Appendix 4) during the treatment period and for at least 2 years after the dose of PL001 and refrain from donating sperm during this period.
- Female Patients:
- A female patient is eligible to participate if she is not pregnant (Section 10.4; Appendix 4), not breastfeeding, and at least one of the following conditions applies:
- +7 more criteria
You may not qualify if:
- Screening 1:
- Chronic lymphocytic leukemia with Richter's transformation.
- Primary CNS lymphoma. (Non-primary CNS lymphoma with CNS involvement is eligible).
- Primary intra-ocular lymphoma.
- Prior CD19 targeted therapy, such as CAR-T, Bi-specific T-cell engagers (BiTE), or monoclonal antibody.
- History of cancers (includes myelodysplastic syndrome) other than non-melanoma skin cancer or carcinoma in situ (e.g., cervix, bladder, breast) unless disease-free without active treatment for at least 3 years.
- History of allogeneic HSCT.
- History of autologous HSCT within 3 months prior to consent.
- Received any investigational product within 4 weeks prior to consent.
- Systemic anticancer therapy within 3 weeks prior to apheresis.
- Long-term use of systemic corticosteroids, defined as daily use \>10 mg of prednisolone or equivalent, within 2 weeks prior to leukapheresis.
- Exception examples:
- Nasal, ophthalmic, inhaled, intra-articular, and topical steroid preparation.
- Short term systemic steroid for drug, contrast, or blood transfusion allergic reaction management.
- Low dose maintenance steroid therapy for other conditions (e.g., asthma).
- +36 more criteria
