About this trial

Despite some encouraging data, systemic treatment of CNS metastases from solid tumors remains experimental.

Better knowledge on the evolving epidemiology and biology of BM are key elements for the development of new treatment strategies and identification of promising therapeutic targets for new compounds. Further biological findings may help to better understand the heterogeneity between the primary tumor and the CNS metastases and to identify new targets for therapy thus improving patients' outcome.

In this context, the Oncodistinct network and the Jules Bordet institute propose to build a multidisciplinary Brain Metastases Clinical Research Platform called BrainStorm. The BrainStorm program will focus on patients with newly diagnosed non-CNS metastatic solid tumors with high risk of developing CNS metastases and will allow building a large clinico pathological database for CNS metastases including ctDNA analyzes from CSF samples. Substudies will be proposed at each time-period with the final objective to develop innovative treatment approaches and strategies.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age ≥ 18 years old

Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2

Female or Male

Eligible for part A: Subjects (from cohorts 1 to 5) with newly diagnosed or up to 24 months from diagnosis of non-CNS metastases. Enrolment of exceptional cases surpassing 24 months from diagnosis will be allowed for up to 20% of subjects enrolled with HER2+ BC (cohort 2) and NSCLC harbouring driver mutations (cohort 3).

Disqualifiers

Pregnant and/or lactating women.

Previous or current malignancies of other histologies within the last 2 years, with the exception of in situ carcinoma of the cervix, and adequately treated basal cell or squamous cell carcinoma of the skin.

Subject with a significant medical, neuro-psychiatric, or surgical condition, currently uncontrolled by treatment, which, in the principal investigator's opinion, may interfere with completion of the study.

Vulnerable persons according to the article L.1121-6 of the Public Health Code, adults who are the subject of a measure of legal protection or unable to express their consent according to article L.1121-8 of the Public Health Code.

To collect data regarding the epidemiology of CNS metastases from solid tumours and identify risk factors for CNS metastases development, including: * Time to the first CNS event * Time to the second CNS after first treatment and subsequent CNS events

Time frame
through study completion, approximately 96 months
2

Better understanding of the epidemiology of CNS metastases from solid tumours

To collect data regarding the epidemiology of CNS metastases from solid tumours and identify risk factors for CNS metastases development, including:: \- Time to whole brain radiotherapy

Time frame
through study completion, approximately 96 months
3

To collect data regarding the epidemiology of CNS metastases from solid tumours and identify risk factors for CNS metastases development, including: \- Overall survival

Time frame
through study completion, approximately 96 months
4

To collect data regarding the biology of CNS metastases by investigating on: \- Presence of CSF-ctDNA at diagnosis of CNS metastases

Time frame
through study completion, approximately 96 months

Secondary outcomes

Other outcomes

1

Better understand the predictive value of NSE for the development of CNS metastases on subjects with newly diagnosed non-CNS metastatic solid tumours with high risk of developing CNS metastases.

To collect data regarding the biology of CNS metastases by investigating on : * Time to the first CNS event * Time to the second CNS event * Time to whole brain radiotherapy (WBR) * Time from the date of diagnosis of the first CNS event and the time of death by any cause

Time frame
through study completion, approximately 96 months
2

Better understand the predictive value of NSE for the development of CNS metastases on subjects with newly diagnosed non-CNS metastatic solid tumours with high risk of developing CNS metastases.

Levels of neuron specific enolase in blood

Time frame
through study completion, approximately 96 months
3

Better understand the predictive value of NSE for the development of CNS metastases on subjects with newly diagnosed non-CNS metastatic solid tumours with high risk of developing CNS metastases.

Deep targeted next-generation sequencing (NGS) on DNA samples from primary or non CNS metastases as well as germline DNA samples and CNS metastases if surgery. A set of 1-3 point mutations (single nucleotide variants) will be selected for each subject based on the above analyses for the identification and quantification of plasma ctDNA and CSF-ctDNA using deep targeted NGS. Subsequently targeted gene sequencing will be performed on DNA samples from CSF and plasma in case of at least 5% tumour mutant allele frequency (MAF) and CNS metastases in case of surgery.

Time frame
through study completion, approximately 96 months
