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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
After completing 4 cycles of R-CHOP chemotherapy, cycles take place every 3 weeks.
A cycle of R-CHOP consists of
Rituximab 375mg/m2 Infusion through a vein on Day 1
Cyclophosphamide 750mg/m2 infusion through a vein on Day 1
Doxorubicin 50mg/m2 Infusion through a vein on Day 1
Vincristine 1.4mg/m2 (2mg max) Infusion through a vein
Prednisolone 100mg/day once a day for 6 days orally with a tablet

Patients will undergo a PET/CT scan if the patient is refractory they will then go on to receive 2 cycles of R-ICE (A cycle of RICE is 21 days) or 2 more cycles of R-CHOP depending on the scan result as reviewed by the physician.
For patients receiving 2 more cycles of R-CHOP they will be assessed at completion of therapy and then every four months with clinical assessment and PET/CT scanning for one year. They will then have a CT neck, chest abdomen and pelvis at 24 months.

A cycle of R-ICE consists of
Rituximab 3752 infusion through the vein on Day 1
Etoposide 100 mg/m2, 20 mins infusion through the vein on Days 1,2 & 3
Carboplatin max 800 mg, 1hr infusion through the vein on Day 1
Ifosfamide + Mesna (each) 5000 mg/m2 infusion through the vein on Days 1, 2 & 3 or as a single 24hr infusion, the treating clinician will decide which way is best for the patient.

Patients will receive another PET/CT scan prior to commencing Lymphodepleting chemotherapy. This consists of either;
Cyclophosphamide 250mg/m2 Infusion through a vein on D-4, D-3, D-2
& Fludarabine 25mg/m2 Infusion through a vein D-4, D-3, D-2
OR
Cyclophosphamide 250mg/m2 orally with a tablet on D-4, D-3, D-2
& Fludarabine 40mg/m2 orally with a tablet on D-4, D-3, D-2
The treating clinician will decide what is the best route of administration based on the patient, local practice and availability.

They will then receive 3 infusions of CAR T cells through a vein.
The first dose of CAR T cells will be on Day 0 after the Lymphodepleting chemotherapy.
Three dose levels will be explored, there will be 4 weeks gap between each dosing.
