CtDNA for Early Response Assessment in PCNSL Treated with 1st Line Curative Intent (NLG-PCNSL-01)

Study Purpose

This is an international, prospective, multicenter trial with the aim of characterizing circulating tumor DNA (ctDNA) for early response assessment in PCNSL patients treated with standard of care (SOC) 1st line therapy with a curative intent (Figure 1). Secondary endpoints are to assess the clinical characteristics, health-related quality of life (HRQoL), neurological status, and outcome of newly diagnosed primary central nervous system lymphoma (PCNSL) patients in the Nordic countries. Patients eligible for a curative intent SOC 1st line therapy, such as MATRix + high-dose chemotherapy and autologous stem cell transplantation (HDCT/ASCT), are eligible for the trial. Diagnostic tumor tissue, cerebrospinal fluid (CSF), and plasma samples are collected for ctDNA and translational analyses with the aim describing new prognostic and predictive biomarkers. Treatment responses are assessed with the International PCNSL Collaborative Group (IPCG) response criteria, and diagnostic and response assessment magnetic resonance imaging (MRI) images are centrally analyzed in order to describe new prognostic and predictive markers.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational [Patient Registry]
Eligible Ages	18 Years - 70 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Age 18-70 years at diagnosis.

- Histologically or cytologically verified diffuse large B-cell lymphoma (DLBCL) of the central nervous system (CNS) - No prior treatment for PCNSL (pre-treatment corticosteroids are allowed and recommended) - Fit for standard of care (SOC) 1st line therapy with a curative intent such as full-dose MATRix, according to local policy.

- Able to give voluntary written informed consent.

- If the patient is temporarily incapacitated to give the voluntary written informed consent, due to PCNSL, the informed consent can be obtained from a legally acceptable representative, according to the International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use - Guideline for Good Clinical Practice (ICH-GCP) guidelines.

Exclusion Criteria:

- Lymphoma outside the CNS.

- History of prior hematological malignancy e.g. low grade B-cell lymphoma.

- Psychiatric illness or condition, other than PCNSL, which could interfere with the ability to understand the requirements of the study

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06755619
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
