Immune Profiles Evolution Under Immunotherapy for Melanoma

Официальное название

Immune Profiles Evolution in Patients Treated by Immunotherapy for Melanoma

Обзор

The primary objective of the study aims to compare the immune profiles (circulating cytokines and lymphocytes) before and after (6 to 8 weeks) the first infusion of immune checkpoint inhibitors in patients with melanoma treated in the adjuvant setting(cohort A) or in metastatic setting(cohort B); and to study the association of these immune profiles with relapse- or progression-free survival.

Подробное описание

This study will analyse the association of biomarkers with relapse- or progression-free survival of stage III or IV melanoma patients, divided in 3 sub-cohorts:

* Patients treated in the adjuvant setting (cohort A): new user of immune checkpoint blockers. * Patients treated in the metastatic setting (cohort B): - B1: new users of immune checkpoint blockers; - B2: prevalent users of immune checkpoint blockers treated with complementary radiotherapy.

For patients of cohort A and B1, immune profiles characteristics will be evaluated before initiation of treatment (=baseline), and at each radiological evaluation of the tumour response, up to maximum 12 months as duration.

The maximal duration of treatment will be 12 months for patients treated in the adjuvant setting. For metastatic patients, the duration of treatment will be decided by physician according to different factors (responses, progression, toxicities, ...).

For patients in cohort B2, the characteristics of the immune profiles will be evaluated before radiotherapy initiation,, within 6 weeks after the end of radiotherapy, then at the 2 following radiological evaluations of the tumour response

Вмешательства

• Процедура venous puncture
  Venous punctures will be performed: for patients of cohort A and B1: * before the first immune checkpoint inhibitors monoclonal antibodies infusion (baseline); * between week 6 and week 8 (before the immune checkpoint inhibitors monoclonal antibodies infusion); * each 3 months up to 12 months. for patients of cohort B2: * before the radiotherapy; * within the 6 weeks after the end of radiotherapy; * at the 2 following evaluations (every 3 months).
• Процедура tumoral biopsy
  Cutaneous biopsy: superficial skin, or extended skin biopsy, if it is indicated for patient's care.
