Brief Summary:
The primary objective of this study is to explore the safety and efficacy of CNCT19 (a second-generation anti-CD19 CAR T-cell using 4-1BB as co-stimulatory domain provided by Juventas, Tianjin, China) infusion following ASCT in patients with relapsed or refractory B-cell lymphoma.

Condition or disease Intervention/treatment Phase
Large B-cell Lymphoma Biological: CNCT19 Drug: Gemcitabine Injection Drug: busulfan Drug: Melphalan Injection Phase 1 Phase 2

Detailed Description:
This is a single-center, non-randomized, open-label, prospective clinical trial to evaluate the safety and efficacy of CNCT19 infusion following high-dose chemotherapy and autologous stem-cell transplantation (HDT/ASCT) in patients with relapsed or refractory B-cell lymphoma. CNCT19 cells will be infused on day +3 (±1d) with a fixed dose of 2×10^6/kg. The study will assess the safety and efficacy of this combinational therapy, including the incidence and severity of cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), hematological, and other non-hematological toxicities, and objective response rates and complete response rates and survivals of the subjects.

Arm Intervention/treatment
Experimental: CNCT19 following ASCT
Participants will receive high-dose chemotherapy followed by stem-cell reinfusion, and a fixed dose of CNCT19 (2×10^6/kg) will be infused in a single-dose on day +2, +3 or +4.
Biological: CNCT19
2×10^6/kg, infused in a single-dose on day +2, +3 or +4 following stem-cell infusion

Drug: Gemcitabine Injection
600mg/m2/h, infused for 3 hours with loading bolus of 75mg/m2, day -7, -3,

Drug: busulfan
105mg/m2, day -7 until -5,

Drug: Melphalan Injection
60mg/m2, day -3, -2




Primary Outcome Measures :
  1. Percentage of participants experiencing adverse events [ Time Frame: from the first day of high-dose chemotherapy until 2 years post CNCT19 infusion ]

Secondary Outcome Measures :
  1. Complete Response (CR) Rate [ Time Frame: 2 years post CNCT19 infusion ]
    Complete Response rate is defined as the incidence of a CR per the Lugano Classification (Cheson et al, 2014), as determined by study investigators.

  2. Objective Response Rate (ORR) [ Time Frame: 2 years post CNCT19 infusion ]
    ORR is defined as the incidence of either a CR or a partial response (PR) per the Lugano Classification as determined by study investigators.

  3. Progression-Free Survival (PFS) [ Time Frame: 2 years post CNCT19 infusion ]
    PFS is defined as the time from the CNCT19 infusion date to the date of disease progression or death from any cause.

  4. Duration of Response (DOR) [ Time Frame: 2 years post CNCT19 infusion ]
    DOR is defined only for participants who experience an objective response after CNCT19 infusion and is the time from the first objective response to disease progression or death from any cause.

  5. Disease-Free Survival (DFS) [ Time Frame: 2 years post CNCT19 infusion ]
    DFS is defined only for participants who achieve complete response after CNCT19 infusion and is the time from complete response to disease progression or death from any cause.

  6. Overall Survival (OS) [ Time Frame: 2 years post CNCT19 infusion ]
    OS is defined as the time from CNCT19 infusion to the date of death from any cause.


Other Outcome Measures:
  1. Levels of CNCT19 in blood [ Time Frame: 2 years post CNCT19 infusion ]
  2. Levels of cytokines in serum [ Time Frame: 1 month post CNCT19 infusion ]
  3. Levels of lymphocyte subsets in blood [ Time Frame: 1 year post CNCT19 infusion ]
