NCT05848765

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • 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 Outcomes (9)

  • Overall metabolic response

    24 weeks

  • Progression free survival (PFS)

  • Overall survival (OS)

  • Duration of response (DoR)

  • Duration of complete response (DoCR)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Biopsy proven relapsed or refractory CD20 positive, grade 1-3a follicular lymphoma (biopsy within 3 months of trial entry)
  • Aged 18 years or over
  • Advanced disease that in the opinion of the treating physician requires treatment
  • Patient suitable for standard available therapy at the Investigator's discretion
  • Prior therapy with at least one line of immunochemotherapy. Previous radiotherapy at any time is permitted and will not count as a line of therapy. Previous rituximab monotherapy is also permitted as long as patients have at any time also received at least one line of immunochemotherapy
  • Assessable disease by PET-CT (at least one involved node with long diameter \>1.5cm, or extranodal lesion \>1cm )
  • ECOG performance status of 0, 1 or 2 at trial entry
  • Adequate organ function defined as; i. ANC ≥ 1.0 x 109/L (growth factor use is permitted) ii. Platelet count ≥ 75 x 109/L, or ≥ 50 x 109/L if bone marrow infiltration or splenomegaly iii. ALT and AST level ≤3 x ULN iv. Direct bilirubin level ≤ 2 x ULN, unless due to Gilbert's syndrome v. CrCl ≥ 50mL/min (by Cockcroft-Gault formula) vi. PT, INR and aPTT ≤ 1.5 x ULN, unless receiving anticoagulation vii. LVEF within normal limits by MUGA or echocardiography
  • Able to provide written informed consent
  • Women of childbearing potential (or their partners) must use an effective form of contraception

You may not qualify if:

  • Current (or within 1 year) transformation to high grade lymphoma, including grade 3b follicular lymphoma (patients with historical high-grade transformation over 1 year ago are eligible)
  • Non-Fluorodeoxyglucose (FDG) avid disease
  • Prior allogenic stem cell transplantation (SCT) or solid organ transplant
  • Prior treatment with lenalidomide
  • Treatment with CAR-T therapy within 100 days of starting trial treatment
  • SCT or maintenance therapy planned within 24 weeks of starting treatment (patients planning SCT/maintenance after at least 24 weeks of treatment are eligible)
  • Immunochemotherapy with a platinum-containing regimen planned
  • Known serological positivity for HIV or uncontrolled HCV
  • Hepatitis B surface antigen (HBsAg) positive and/or detectable viral DNA. Patients positive for Hepatitis B core antibody (anti-HBc) but viral DNA negative are eligible
  • Other malignancy within 2 years of enrolment, excepting cervical carcinoma stage 1B or less, non-invasive basal cell or squamous cell skin carcinoma, non-invasive, superficial bladder cancer, prostate cancer with a current PSA level \<0.1ng/mL, any curable cancer with a CR of \> 2 years duration
  • Active systemic infection requiring treatment
  • Current or prior CNS involvement with lymphoma
  • History of allergy or anaphylaxis to anti-CD20 monoclonal antibody therapy
  • 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.
  • Serious medical or psychiatric illness likely to interfere with participation in this clinical study
  • +6 more criteria
