Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Description of intervention(s) / exposure: The study intervention is MB.CART19.1 CD19 CAR T cell therapy, which is a type of gene-modified immune cell made from the participant’s blood cells. The participants will undergo a medical assessment to assess suitability for CAR T cell therapy. He or she will then undergo leukapheresis, which is a procedure where a large number white blood cells are collected through the veins. The volume collected is 240 – 300 mL. The blood cells are taken to the hospital laboratory to be made into MB.CART19.1 CAR T cells. Where medically safe, the participants will be given intravenous chemotherapy, consisting of fludarabine 25mg/m2/day for 3 days and cyclophosphamide 250mg/m2/day for 3 days, prior to MB.CART19.1 CAR T cell infusion. Participants who are unable to safely undergo chemotherapy can still receive MB.CART19.1 CAR T cell infusion. The MB.CART19.1 CAR T cells is in a volume of up to 150mL and is given by a specialist nurse and usually takes less than 30 minutes. Participants will need to stay in hospital for a few days before and after MB.CART19.1 CAR T cell infusion and attend regular follow-up visits after hospital discharge. This is at least once a week for 4 weeks, then monthly for 3 months, 3-monthly for 2 years after cell infusion, and then yearly for up to 15 years. Only a single dose of CAR T cell is administered but additional doses are permitted in specific settings, which include loss of CAR T cells, re-emergence of B cells, and persistent or recurrent B cell cancer, provided additional cells are available and the participants consent to additional infusion and are at least four weeks after their most recent infusion.
