SAKK 38/19: Assessing a ctDNA and PET-oriented therapy in patients with DLBCL. A multicenter, open-label, phase II trial
EU CTIS ID: 2024-516740-26-00
What this study is testing
Assessing the efficacy of acalabrutinib-R-CHOP in DLBCL harboring MYD88 L265P and/or CD79A/B mutations (cohort A) Assessing the activity of treatment escalation to acalabrutinib-R-CHOP followed by acalabrutinib monotherapy in DLBCL patients who are double positive: PET/CT positive (Deauville score 4 or 5 with centrally defined response) and no molecular response ( 2log10 reduction of ctDNA) after two cycles of R-CHOP (cohort C). Exploring clinical implications of having a negative PET/CT (Deauville score 1-3) but no molecular response ( 2log10 reduction of ctDNA) after two R-CHOP courses (cohort D)

You likely can't join if
- CNS lymphoma involvement.
- Major surgery in the preceding 4 weeks of first dose of study drug. If a subject had major surgery, they must have recovered adequately from any toxicity and/or complications from the intervention before the first dose of study drug.
- Malabsorption syndrome, disease significantly affecting gastrointestinal function, resection of the stomach or small bowel, gastric bypass, symptomatic inflammatory bowel disease, or partial or complete bowel obstruction or gastric restrictions and bariatric surgery, such as gastric bypass.

- Known history of human immunodeficiency virus (HIV) or active chronic hepatitis C or hepatitis B virus infection or any uncontrolled active systemic infection requiring intravenous (iv) antimicrobial treatment. All patients must be screened for HIV up to 28 days prior to study drug start using a blood test for HIV according to local regulations. All patients must be screened for hepatitis up to 28 days prior to study drug start using the routine hepatitis virus laboratory panel. Patients positive for hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) will be eligible if they are negative for HBV-DNA, these patients should receive prophylactic antiviral therapy and have HBV-DNA testing every 4 months. Patients positive for anti-HCV antibody will be eligible if they are negative for HCV-RNA.
- Active, uncontrolled autoimmune phenomenon (autoimmune hemolytic anemia or immune thrombocytopenia) requiring steroid therapy with > 20 mg daily of prednisone dose or equivalent.

- Patient is willing to participate in translational research projects.
- Histologically confirmed, treatment-naïve DLBCL, NOS that fulfill all the following: - Patient eligible for 6 cycles of R-CHOP - Ann Arbor stage I-IV (see Appendix 2) - Metabolically active measurable disease by 18FDG PET-CT - No previous treatment with systemic chemotherapy or radiotherapy (a pre-phase treatment with steroids for up to a total of 10 days is allowed; baseline PET/CT, liquid biopsy and bone marrow biopsy and aspirate must be collected either before or within a maximum of 5 days after steroid pre-phase treatment starts. If a patient receives steroids, glucose levels must be checked and be normal on the day of PET/CT before the exam. - At least 1 measurable site of disease according to Revised Response Criteria for Malignant Lymphoma. The site of disease must be greater than 1.5 cm in the long axis regardless of short axis measurement or greater than 1.0 cm in the short axis regardless of long axis measurement, and clearly measurable in 2 perpendicular dimensions. - Quantifiable and qualifiable circulating tumor DNA
- Patients with a prior malignancy and treated with curative intention are eligible if all treatment of that malignancy was completed at least 2 years before registration and the patient has no evidence of disease at registration. Less than 2 years is acceptable for malignancies with low risk of recurrence and/or no late recurrence.
- Age ≥ 18 years.
- EGOG performance status 0-2 (or 3 if due to disease).
- Adequate bone marrow function: neutrophil count ≥ 1.0 x 109/L, platelet count ≥ 75 x 109/L (unless due to bone marrow involvement: in this case the permitted limit is ≥ 50 x 109/L) with allowed premedication or supportive medication.
