Summary

The circulating tumoral biomarkers in the blood are the object of numerous researches for several decades. The potential clinical interests of these circulating biomarkers are diagnostic, prognostic, predictive of the efficiency of targeted therapies (according to the mutational profile of the cancer), and could allow the study of the mechanisms of resistance under process. In the multiplicity of these blood potential biomarkers joins a permanent evolution of the technological means used to detect them/to quantify, as well as to estimate their clinical utility.

Detailed description

The new major challenge in the research concerns the circulating biomarkers, which aim at replacing the molecular analyses on tumour tissue obtained by biopsy (for example the search for somatic mutations of cancer) by a simple blood test (liquid biopsy). The other current important challenge is to have an idea of the interest to analyse the kinetics of blood markers, in particular in answer to a clinical "event", either through the chemotherapy, a biopsy and / or surgery. There is almost no data in the literature on this aspect. It is very likely that the liberation in the blood of the blood tumoral markers is strongly dependent on medical interventions on the tumour. The study ALCINA 2 rests exactly on the principle of small cohorts, which correspond each to a clinical situation and/or a technique of different implemented detection, so as to generate data of feasibility and proof of concept. In case of success, statistical hypotheses will be necessary for the implementation of wider studies (being then the object of a specific approval by competent authorities).

Interventions

Type	Name	Description
BIOLOGICAL	Blood sampling	blood sampling time : cycle 1 day 15 and cycle 2 day 15 : one sample (6ml) by time
BIOLOGICAL	Blood sampling C3	Blood samples will be collected at four key time points: * baseline (T1), * first scan assessment (T2), * second scan assessment (T3), * and progression (T4).
BIOLOGICAL	Blood sampling C4/7/10/13	Blood samples will be collected before any treatment
BIOLOGICAL	Blood sampling C5	Blood samples will be collected at four key time points: * At the inclusion (T1) * Before the beginning of the treatment (cycle 1 day 1) (T2) * After the first cycle of T-DXd (cycle 2 day 1) (T3) * At progression or at the end of the follow-up (after 3 years) (T4)
BIOLOGICAL	Blood sampling C6	Blood samples will be collected at three key time points: * At the inclusion (T1) * For patients starting treatment at the time of inclusion (T2): * Chemotherapy: 3 months after inclusion, * Concurrent chemoradiotherapy with Temozolomide: 4-6 weeks after completion of radiotherapy, * For patients starting treatment at the time of inclusion: at the time of tumor progression if occurring within one year of inclusion, or 12 months after inclusion in the absence of progression (T3).
BIOLOGICAL	Blood sampling C8	Blood samples will be collected at five key time points: * At the inclusion * At follow-up visit 2 to 6, every 3 months
BIOLOGICAL	Blood sampling C9	Blood samples will be collected at four key time points: * At the inclusion before the beginning of the treatment (Cycle 1 Day 1) * After the first cycle of the first chemo-immunotherapy sequence (Cycle 2 Day 1) * After the first cycle of the second chemotherapy sequence (Cycle 2b Day 1) * After the end of the whole neo-adjuvant chemo-immunotherapy protocol, before surgery
BIOLOGICAL	Blood sampling C11 + FFPE	Blood samples will be collected at five key time points: * At the inclusion (T1) * At first clinical evaluation (T2): 4th week after start of treatment * At first scan evaluation (T3a): 8th week after start of treatment * At the Nth scan evaluation (T3b, c, ...) * At progression (T4) Tumor sampling : * At the inclusion * At tumor progression
BIOLOGICAL	Blood sampling C12	Blood samples will be collected at several points : * Inclusion: at the time of suspected leptomeningeal metastases, prior to any specific treatment, * Every 4 weeks until meningeal progression, or for a maximum of 4 months, * Then every 3 months beyond 4 months until meningeal progression.
