Tailoring Treatment for B Cell Non-hodgkin's Lymphoma Based on PET Scan Results Mid Treatment (LYTPET)

July 20, 2021 updated by: British Columbia Cancer Agency

Phase II Trial Investigating Tailoring First-Line Therapy For Advanced Stage Diffuse Large B-Cell Non-Hodgkin's Lymphoma Based on Mid-Treatment Positron Emission Tomography (PET) Scan Results

The purpose of this study is to assess whether patients who are likely to fail R-CHOP, as predicted by a mid-treatment PET scan, can have an improved outcome if switched to a standard salvage regimen R-ICE (rituximab, ifosfamide, carboplatin, etoposide).

Patients who have a negative PET scan after 4 cycles of R-CHOP have an excellent prognosis (>85% chance of cure) and should complete treatment with 6 cycles of standard R-CHOP. Patients who have a positive PET scan after 4 cycles of R-CHOP have a very poor prognosis (~10% chance of cure) and may have an improved outcome if switched to a non-cross resistant chemotherapy combination R-ICE.

Study Overview

Detailed Description

This is a phase II trial investigating tailoring first-line therapy for advanced stage diffuse large B-cell NHL (DLBCL) based on a mid-treatment 18F-FDG- positron-emission tomography (PET) scan result. More than half of all patients with DLBCL can be cured with 6-8 cycles of standard R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). Patients who are not cured with R-CHOP have a very poor prognosis. This study will assess whether patients who are likely to fail R-CHOP, as predicted by a mid-treatment PET scan, can have an improved outcome if switched to a standard salvage regimen R-ICE (rituximab, ifosfamide, carboplatin, etoposide).

Objectives:

  • To assess the efficacy of tailoring first-line therapy based on a mid- treatment PET scan result for patients with advanced stage DLBCL.
  • To assess the progression-free survival (PFS) in patients with advanced stage DLBCL who have a negative mid-treatment PET scan and receive standard therapy with six cycles of CHOP-R and patients with a positive mid-treatment PET scan who receive four cycles of CHOP-R followed by four cycles of R-ICE chemotherapy.
  • To assess the overall survival (OS) in patients with advanced stage DLBCL who have a negative mid-treatment PET scan and receive standard therapy with six cycles of CHOP-R and patients with a positive mid-treatment PET scan who receive four cycles of CHOP-R followed by four cycles of R-ICE chemotherapy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: R-CHOP (Negative Mid-Treatment PET Scan)
All participants will receive 4 cycles of standard dose R-CHOP chemotherapy administered at 3-weekly intervals. Non-progressing participants will undergo a mid-treatment PET scan along with routine restaging investigations after 4 cycles of R-CHOP. Patients with a negative mid-treatment PET scan (no evidence of abnormal 18F-FDG uptake) will complete therapy with two additional cycles of R-CHOP for a total of 6 cycles of chemotherapy. Patients with a mid-treatment PET scan interpreted to be "indeterminate" or "equivocal" will be recorded as such, but should be considered negative for the purpose of treatment planning and should not prompt a change in therapy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression-free survival (PFS) in participants with advanced stage DLBCL
Time Frame: Estimated two years

Progression-free survival (PFS) in participants with advanced stage DLBCL who have a negative mid-treatment PET scan and receive standard therapy with six cycles of CHOP-R and patients with a positive mid-treatment PET scan who receive four cycles of CHOP-R followed by four cycles of R-ICE chemotherapy.

Progression-free survival is defined as the duration of time from diagnosis to time of disease progression or death from any cause. Living patients who have remained free of progression will have their PFS censored on the date last known alive.

Estimated two years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall survival (OS) in participants with advanced stage DLBCL
Time Frame: Several years

Overall survival (OS) in participants with advanced stage DLBCL who have a negative mid-treatment PET scan and receive standard therapy with six cycles of CHOP-R and patients with a positive mid-treatment PET scan who receive four cycles of CHOP-R followed by four cycles of R-ICE chemotherapy.

Overall survival will be defined as the time from diagnosis to the date of death. If the participant is lost to follow-up, survival will be censored on the last date the participant was known to be alive.

Several years
The safety of R-ICE therapy in first-line therapy of DLBCL following four cycles of R-CHOP as assessed using the NCI Common Terminology Criteria for Adverse Events Version 3.0
Time Frame: Six months
Six months
Investigate clinical and biologic markers that characterize participant heterogeneity and may serve as predictors of response to therapy and overall outcome.
Time Frame: 1 year

A central pathology review of original diagnostic biopsies will be performed by pathologists at the Coordinating Center to ensure appropriate lymphoma subclassification. This centralized review is not required prior to enrollment, provided the patients biopsy has been carefully reviewed by local pathologists and determined to be DLBCL.

Correlative studies of biologic markers will be performed on cases with adequately preserved tissue to explore the biologic heterogeneity between patients and to investigate determinants of response to therapy.

1 year
Efficacy of tailoring first-line therapy bases on a mid-treatment PET scan result for patients with advanced stage DLBCL
Time Frame: Four to six months
All patients will have their BEST RESPONSE on study classified as outlined below. For patients with more than six measurable lesions the six most distinctly measurable at diagnosis should be chosen for response assessment by CT scanning. If available, lesions from both above and below the diaphragm should be chosen, at least two from each region.
Four to six months
