Intervention  HCAR19 cells   At IIT-Bombay, a novel and indigenous HCAR19 cell product has been designed and developed. The gene therapy product (GTP) has been tested for the ex vivo and in vivo functionality and the results are quite promising. Autologous T-cells will be transduced using a lentiviral vector that will contain a gene coding for a single chain variable fragment (scFv) directed against the surface CD19 antigen. The cells will also express an intracellular signalling domain made of 4-1BB and TCRζ signalling modules. Clinical grade viral vector used for this process will be manufactured at IIT-Bombay. The humanized scFv is designed from FMC63 scFv (murine anti-human CD19 antibody). The signalling domains will be from the native human sequence. Patients will receive the CAR-T cell product as a split-regimen at 10%, 30% and 60% dose on Days 0, 1 and 2 respectively. The minimum dose to be administered is 1x10 raise to power 7 CAR-T cells to a maximum of 5x10 raise to power 9 CAR- T cells. The product will be infused in a single room at Tata Memorial centre, using precautions for immunocompromised patients. The product will be infused at 10-20 ml/min via an 18-G latex free Y- type blood set with a 3-way stopcock.

Brief Summary
Diffuse large B-cell lymphoma (DLBCL) accounts for 30% of all the cases of Non-Hodgkin lymphoma (NHL). Two-thirds of patients respond to frontline chemoimmunotherapy. Only 5 per cent of relapsed/refractory DLBCL responds to salvage chemotherapy and could undergo stem cell transplant. There is a large unmet need to be addressed in the relapsed/refractory setting. The CAR-T cell therapy directed against CD19 shown significant clinical benefit. Two CAR-T cell therapy products are granted FDA approval, namely Axicabtagene ciloleucel (Yescarta) and Tisagenlecleucel (Kymriah). The cost of therapy is exorbitant. Therefore, we need to develop an indigenous product with less production costs and make it accessible to our patients. 
Our hypothesis is that HCAR19 cell product is safe with manageable toxicities. The primary objective of the study is to assess the safety and tolerability of a clinical-grade HCAR19 cells product in relapsed/refractory
DLBCL subjects by recording the frequency and severity of adverse events reporting, including but not limited to, estimating the frequency of cytokine release syndrome ( CRS) and Macrophage activation syndrome (MAS). The secondary objectives of the study is to know the objective response rate, 2-year event-free survival and overall survival, late complications of therapy, to evaluate engraftment of CAR T cells, to study the change in the cytokines, to know phenotype and function of cells, to know manufacturing feasibility. Relapsed/refractory (r/r) patients of age greater than or equal to 18 years with DLBCL, primary mediastinal B-cell lymphoma or transformed high grade B-cell lymphoma (Defined as per the WHO 2016 criteria) and unable to undergo stem-cell transplants will be included in the study. Clinical and laboratory monitoring of patients for complications including Cytokine Release Syndrome (CRS), management of patients and documentation, and management of Serious Adverse Effects (SAEs) over immediate and extended follow up periods till 3 months of therapy will be done. Disease remission status will be monitored by 18-FDG PET-CT scans at Day 90, it will be repeated after every 3 months if patient is not in complete remission. Monitoring will be done monthly basis till the completion of 6 months. After that patient will be monitored 3 monthly till the completion of 2 years. Thereafter patient will be followed up after every 6 months till the completion of 5 years. Finally, there will be an annual follow up till the completion of 10 years. We have taken approval from RCGM and Ethics Committee. DCGI approval has also been obtained.
