Brief Summary

Determine MTD based on the safety and tolerability of AT101 and the RP2D for patients with recurrent or non-reactive B-cell NHL.

Detailed Description

Inclusion Criteria
  • B cell non-Hodgkin lymphoma based on WHO classification 2017
  • incompatible with existing standard therapies or have had disease progression, and whose standard therapies do not currently have available standard therapies due to reasons such as intolerance/inadequacies or rejection
  • The Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
  • adequate hematological, kidney, liver, lung, heart and bone marrow function without blood transfusion within two weeks prior to screening
  • Those with a minimum life expectancy of 12 weeks or more
  • In women with childbearing, clinical response tests (serum- or ure-hCG) were negatively identified during this trial
  • Those who have agreed in writing to participate voluntarily in this trial
Exclusion Criteria
  • Those who have previously had a history of treating homologic autologous hemoblastitis (allogeneic HSCT)

  • At101/adcidmilisers, anticancer chemotherapy/adcidms for lymphodeletion or those who are hypersensitive to tocilizumab

  • Those who cannot take autologous blood

  • Those who have received chemotherapy or radiotherapy, excluding lymphodeletion, within two weeks prior to IP administration

  • Persons who have not been recovered (CTCAE grade ≤1 or baseline) due to previous treatment

  • Those who have identified a condition that, at the test's discretion, may affect safety and validation during the trial period.

  • Those who have identified the following forces at the time of screening:

    1. Those who have been clinically aware of heart disease within 6 months prior to screening
    2. Those identified as thromboembolic disease, pulmonary embolism or bleeding bleeding diatheses within 6 months prior to screening
    3. Those who have identified a history of malignant tumors other than B-cell non-Hodgkin's lymphoma within five years prior to screening
    4. Those who have undergone major surgery within 4 weeks prior to screening
    5. Those who have undergone non-critical surgery within two weeks prior to screening
  • Childbearing women or men who do not have the will to use effective contraception for a longer period of time, either 12 months after clinical trial period and AT101 administration or when AT101 in the body is not identified

  • Those who have been administered or applied to other IP/ID within 4 weeks of screening

  • Those who are addicted to alcohol and/or medication

  • Those who are unfit or unable to participate in this trial when judged by PI
