Proton Cranio-spinal Irradiation for Leptomeningeal Metastasis

Study Purpose

Leptomeningeal metastasis is a rare but serious complication to cancer, with a grave prognosis. No efficient treatment exists. Recent data suggest that craniospinal radiotherapy lead to superior survival and CNS control compared to focal photon radiotherapy. We want to offer Danish patients the new treatment, but within a protocol, as this is new data with an new treatment principle

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.	Interventional
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Metastasis to the leptomeningeal space (LM) surrounding the brain and/ or spinal cord.

- Metastasis verified by MRI or CSF cytology.

- Karnofsky >=60 (requiring some help, can take care of most personal requirements) - Adequate bone marrow function.

- Haemoglobin > 5 mmol/l.

- Absolute neutrophil count >1 10^9/l.

- Platelet count > 100 10^9/l.

- Patient consent.

- Female subjects must either be of non-reproductive potential ( ≥ 60 years old, or with no menses for >1 year without an alternative medical cause], OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a pregnancy test within 2 weeks prior to starting treatment.

- Patient at reproductive potential must agree to practice an effective contraceptive method.

Exclusion Criteria:

- • Previous radiotherapy to the intended treatment site that precludes developing a treatment plan that respects normal tissue tolerances (Yang) - Patient with multiple, serious major neurologic deficits per physician/investigator assessment including encephalopathy.

- Patient with extensive systemic disease and without reasonable systemic treatment options.

- Patient who is unable to undergo MRI brain and spine with gadolinium contrast.

- Pregnant or lactating women.

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.	NCT05746754
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.	N/A
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	University of Aarhus
Principal Investigator The person who is responsible for the scientific and technical direction of the entire clinical study.	N/A

Patients with leptomeningeal metastasis from both solid and hematological cancers will be offered proton radiotherapy with 30 Gy in 10 fractions to the entire craniospinal axis. Patients will be followed with registration of side effects, neurology and MRI scans every 3 months until 1 year.
