Phase II multicenter clinical trial: Mosunetuzumab for early relapse of follicular lymphoma in the Nordic countries (MERLIN/NLG-FL6/ML43841)
EU CTIS ID: 2022-500100-21-01
What this study is testing
The primary objective is to investigate the efficacy of 2nd line treatment with subcutaneous mosunetuzumab monotherapy in FL with refractory disease, progression or relapse of disease within 24 months of starting 1st line treatment (POD24).

Who can take part
You may be able to join if
- Written informed consent according to ICH-GCP guidelines
- Age ≥ 18 years
- Follicular lymphoma grade 1-3a with a current relapse or progression within 24 months of starting 1st line treatment or refractory to 1st line treatment (POD24), more specifically: a. Documented current relapse or progression of FL within 24 months of starting first line treatment containing a monospecific anti-CD20 antibody (such as rituximab or obinutuzumab with or without chemotherapy, small molecular inhibitors or immunomodulating agents such as lenalidomide). b. Alternatively, current lack of response/refractoriness to first line treatment, i.e., no objective response or documented progression within 6 months following at least four cycles of monotherapy with a monospecific anti-CD20 antibody (such as rituximab 375mg/m2 iv or 1400 mg SC or equal) or following at least three cycles of a monospecific anti CD20 antibody combined with chemotherapy, small molecular inhibitors or immunomodulating agents such as lenalidomide. c. Received one prior treatment line of systemic therapy. d. If the POD24 event was diagnosed more than three months ago, then study inclusion has been clarified with the coordinating investigator. e. Patients may have received localized radiotherapy previously. Patients may have received localized radiotherapy previously. If the radiotherapy was recent, the patient must have at least one progressive and measurable lesion outside the radiation field.
- At least one two-dimensionally measurable lesion with a longest diameter >15mm.
- WHO performance status 0-2. Patients with reduced WHO performance status (> 2) can be considered if reduction in performance is caused by the lymphoma as determined by the investigator.
You likely can't join if
- Received 2 or more previous treatment lines.
- Impaired liver function not caused by lymphoma, defined as serum total bilirubin ≥ 1.5 x ULN (unless elevated due to Gilbert’s syndrome) or serum ALT and AST ˃ 3 x ULN
- Impaired renal function not caused by lymphoma, defined as calculated creatinine clearance <= 40 ml/minute
- Grade 3b FL.
- Other major organ dysfunction not caused by lymphoma
- Known history of drug induced liver injury, chronic active hepatitis C (HCV), chronic active hepatitis B (HBV), alcoholic liver disease, primary biliary cirrhosis, on-going extra-hepatic obstruction caused by cholelithiasis, cirrhosis of the liver or portal hypertension.
