Refractory Follicular Lymphoma Clinical Trial
— REFRACTOfficial title:
Relapsed Follicular Lymphoma Randomised Trial Against Standard ChemoTherapy (REFRACT): A Randomised Phase II Trial of Investigator Choice Standard Therapy Versus Sequential Novel Therapy Experimental Arms
The aim of the REFRACT clinical trial is to find new therapies with improved outcomes compared to the current standard treatment available, in patients with relapsed or refractory follicular lymphoma. This will be done by comparing patients who have received a new treatment against patients who receive standard treatment based on their response to the treatment received.

Active systemic infection requiring treatment 12. Current or prior CNS involvement with lymphoma 13. History of allergy or anaphylaxis to anti-CD20 monoclonal antibody therapy 14. Known hypersensitivity to any of the experimental arm IMPs. Patients with a known hypersensitivity to a control arm regimen may still be eligible if they have no hypersensitivity to other potential control arm IMPs. 15. Serious medical or psychiatric illness likely to interfere with participation in this clinical study 16. Recent cancer treatment (chemotherapy, immunotherapy, biological therapy) within 4 weeks of starting trial treatment; systemic steroid treatment (prednisolone > 10mg daily (or equivalent)) within 7 days of cycle 1 day 1 dosing 17. Unwilling to use appropriate contraception methods whilst on study treatment and for 12 months following end of treatment (or 18 months for female patients whose ICT regimen contains obinutuzumab) 18. Women who are pregnant or breastfeeding 19. Prior treatment with the experimental therapy under investigation 20. Major surgery within 30 days of starting treatment 21. Severe arrhythmias, heart failure, previous myocardial infarction, acute inflammatory heart disease for ICT regimen containing doxorubicin, or severe heart failure (New York Heart Association Class IV) or severe, uncontrolled cardiac disease for ICT regimen containing rituximab |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Complete metabolic response (CMR) | CMR will be assessed by PET-CT using the Deauville 5-point scale and Lugano 2014 criteria. Patients who die from any cause or relapse/progress prior to this time-point will be considered non-responders. Patients who don't have a PET-CT scan within the protocol defined window or withdraw from the trial prior to this time-point will be considered non outcome evaluable. Patients who undergo stem-cell transplant (SCT) within 24 weeks of randomisation, patients who fail to start treatment and patients whose ineligibility is deemed to impact upon response to treatment will be replaced and hence not included in the analysis of this outcome | 24 weeks | |
Secondary | Overall metabolic response | Complete metabolic response (CMR) and partial metabolic response (PMR) will be assessed by PET-CT. Patients who die from any cause or relapse/progress prior to this time-point will be considered non-responders. Patients who undergo stem-cell transplant (SCT) within 24 weeks of randomisation, patients who fail to start treatment and patients whose ineligibility is deemed to impact upon response to treatment will be replaced and hence not included in the analysis of this outcome | 24 weeks | |
Secondary | Progression free survival (PFS) | The time from randomisation to the date of first disease progression or death. Patients who are alive and relapse/progression at the time of analysis will be censored at their date last seen | 10 years | |
Secondary | Overall survival (OS) | The time from randomisation to the date of death from any cause. Patients who are alive at the time of analysis will be censored at their date last seen | 10 years | |
Secondary | Duration of response (DoR) | The time from complete and partial metabolic response by PET-CT to relapse/progression or death from any cause. Patients who are alive and relapse/progression free at the time of analysis will be censored at their date last seen | 10 years | |
Secondary | Duration of complete response (DoCR) | The time from complete metabolic response by PET-CT to relapse/progression or death from any cause. Patients who are alive and relapse/progression free at the time of analysis will be censored at their date last seen | 10 years | |
Secondary | Time to next treatment (TTNT) | The time from randomisation to the start date of next treatment for lymphoma. Patients who are responding (CMR or PMR) who receive consolidation radiotherapy will not be considered an event and will be censored at their date last seen if no other treatment for lymphoma is reported. Patients who die without having started next lymphoma treatment will be considered a competing risk at their date of death, and patients who are alive and have not started next lymphoma treatment at the time of analysis will be censored at their date last seen | 10 years | |
Secondary | Adverse events (AEs) | Collected and reported in accordance with CTCAE version 5 defined as the number of patients who experience one or more grade 3 or 4 adverse events or serious adverse events of any grade | Collected from start of treatment until 60 days after treatment | |
Secondary | Quality of Life (QoL) | Measured using the EQ-5D-5L and FACT-Lym | Collected pre-treatment, day 1 of cycle 3 (28 day cycles), 24 weeks from treatment start and then every 24 weeks in non-progressed patients until the end of the study (10 years) | |
Secondary | Quality of Life (QoL) | Measured using the FACT-Lym | Collected pre-treatment, day 1 of cycle 3 (28 day cycles), 24 weeks from treatment start and then every 24 weeks in non-progressed patients until the end of the study (10 years) |
