Clinical Trial Summary

Immunotherapy is widely administrated as anticancer treatment in metastatic setting. Despite a proved efficacy in several cancer types and clinical situations, it exists a wide variability of responses in terms of efficacy and toxicity. The rate of responders depends mostly on the type of pathology, with 40% of responders among melanoma patients, 20-30% among lung and head and neck cancer patients and only 1% of responders among pancreatic cancer patients. Thus, the main challenge today is to be able to select patients for whom the treatment is likely to be effective. Several studies suggested that tumors with a high mutational burden and expressing PD-L1 are better responders to immunotherapy.

However, a proportion of PD-L1 negative cancers responds to immunotherapy, suggesting that other parameters have to be considered together with PD-L1 expression. Of that, the immunotherapy clearance seems to have an impact on overall survival, but larger studies, including different molecules and cancer types, are needed to better understand the correlation between the clearance and the response to immunotherapy.

Tumor cells released from the primary tumor in the blood circulation (CTCs, for circulating tumor cells) are considered as "liquid biopsies", as they contain the entire genetic and phenotypic information representative of the tumor, including PD-L1 expression. Thus, the variation of PD-L1 expression under treatment can be easily followed-up on blood samples collected during the time.

The objective of MADMAS is to study the correlation between the immunotherapy clearance, measured at the different times during treatment, and the variation of the number of CTCs expressing PD-L1 after two cures of treatment.

MADMAS will enroll patients with lung or head and neck cancers, treated with an immunotherapy-based therapy. Blood samples will be collected at the baseline and before the first two cures of treatment. The immunotherapy clearance will be measured with an innovative approach of Mass Spectrometry, and PD-L1 expression will be measured on CTCs, purified with a highly sensitive microfluidics technology.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Immunotherapy clearance (mL/min) and number of PD-L1 (absolute number) positive CTCs after two cycles of treatment (composite criteria)	The clearance and the number of PD-L1 positive cells will be measured on blood samples collected the day of the third immunotherapy administration (each cycle is 14 to 28 days, depending on the type of immunotherapy).	At the end of cycle 2 (each cycle is 21 days)
Secondary	Overall survival	time elapsed between the first immunotherapy administration and the death	2 years
Secondary	Progression free survival	time elapsed between the first immunotherapy administration and progression	2 years
Secondary	level of PD-L1 expression on primary tumor tissue	The level of PD-L1 expression will be measured by ICH on tissue from primary tumor surgery/biopsy through study completion, an average of 2 years.	2 years
Secondary	Baseline transcriptomic profile of CTCs isolated form peripheral blood	Baseline transcriptomic profile of CTCs isolated form peripheral blood: the transcriptomic profile of CTCs will be analyzed by NGS (Next-Generation Sequencing) from blood samples collected at cycle 1 day 1, before treatment administration.	Day 1 of cycle 1, before treatment administration (cycle length: 14 days for nivolumab treatment and 21 days for pembrolizumab treatment)
Secondary	1st cycle transcriptomic profile of CTCs isolated form peripheral blood	The transcriptomic profile of CTCs will be analyzed by NGS (Next-Generation Sequencing) from blood samples collected after the 1st cycle of treatment (cycle length between 14 and 21 days depending on the type of immunotherapy)	Day 1 of cycle 2, before treatment administration (cycle length: 14 days for nivolumab treatment and 21 days for pembrolizumab treatment)
Secondary	2nd cycle transcriptomic profile of CTCs isolated form peripheral blood	The transcriptomic profile of CTCs will be analyzed by NGS (Next-Generation Sequencing) from blood samples collected at the end of cycle 2 (each cycle is 21 days).	Day 1 of cycle 3, before treatment administration (cycle length: 14 days for nivolumab treatment and 21 days for pembrolizumab treatment)
Secondary	identification of CTCs transcriptomic signatures, associated to immunotherapy efficacy or toxicity	the CTCs transcriptomic profile (measure 4) will be obtained with the NGS method; the analyses of these profiles will imply statistical models of logistic regression (Lasso Method). These data will be compared with clinical data on efficacy (PFS measured at 2 years after the beginning of treatment) and toxicity (stopping treatment for toxicity before the third cycle).	2 years
