• INCLUSION CRITERIA FOR CANCER PATIENTS ONLY
7. Patients currently off treatment with histologically or cytologically confirmed
following diagnosis:
- Cohort 1: Unresectable, locally advanced or metastatic Non-Small Cell Lung cancer
after at least 1 or 2 standard treatment lines (including 1 line with Immune
Checkpoint Inhibitor) and being scheduled for a new anti-cancer treatment after
progression
- Cohort 2: Unresectable, locally advanced or metastatic Colorectal cancer after at
least 2 treatment lines
- Cohort 3: Unresectable, locally advanced or metastatic Pancreatic cancer after at
least 1 or 2 treatment lines

after at least 1 treatment line
- Cohort 5: Unresectable, locally advanced or metastatic Gastric cancer after at
least 1 treatment line Unresectable, locally advanced or metastatic
Cholangiocarcinoma before or after at least 1 treatment line
- NON-INCLUSION CRITERIA FOR ALL PARTICIPANTS (PATIENTS WITH CANCER AND
HEALTHY VOLUNTEERS)
8. Pregnant women
9. Subjects with an active autoimmune disease that is currently requiring systemic
anti-inflammatory treatment such as disease-modifying anti-rheumatic drugs [DMARDs],
steroids, or immunosuppressants), except vitiligo, alopecia areata, asthma/atopy and
psoriasis treated and controlled by topical therapies. Patients with auto-immune
endocrinopathies that are well treated by replacement hormones therapies (e.g.
thyroxine, insulin, physiological steroids for adrenal or pituitary) are allowed.
Patients with a history of immune related adverse events (irAEs) from a previous line
of treatment must have resolved their irAEs to a grade =1 and have stopped any
immunosuppressive/steroid therapy
10. Subjects with any serious/active/uncontrolled infection, any infection requiring
parenteral antibiotics, or unexplained fever >38ºC within 2 weeks prior to blood
withdrawal.
11. Subjects who have had a laboratory-confirmed SARS-CoV-2 infection as determined by
polymerase chain reaction (PCR) test within 60 days prior to blood withdrawal.
12. Patients seropositive for and with evidence of active viral infection with hepatitis B
virus (HBV). Patients who are hepatitis B surface antigen (HBsAg) negative and HBV
viral DNA negative are eligible.
1. Patients who had HBV but have received an antiviral treatment and show
non-detectable viral DNA for 6 months are eligible.
2. Patients who are seropositive because of HBV vaccine are eligible. Note: a
quantitative PCR test result of < 10 IU/mL is equivalent to being undetected
(negative). Subject with no available results for hepatitis B virus (HBV) are
eligible.
13. Patients seropositive for and with active viral infection with hepatitis C virus
(HCV). Patients who had HCV but have received an antiviral treatment and show no
detectable HCV viral DNA for 6 months are eligible.
Note: a quantitative PCR test result of < 10 IU/mL is equivalent to being undetected
(negative). Subject with no available results for hepatitis C virus (HCV) are
eligible.
14. Subjects who have received prior systemic anticancer therapy, definitive radiotherapy
(palliative radiation therapy is allowed), or other investigational agents or device

therapeutic agents whatever the shortest). Patients who are in the screening period of
an investigational study may participate if they are currently off-treatment. Patients
who have entered the follow-up period of an investigational study may participate if
it has been 2 weeks after the last dose of the previous investigational agent.
15. Subjects who have received approved or investigational immunomodulators (targeting any
immune cell types, such as anti-CTLA-4, anti-PD-L1, any immunomodulatory in a clinical
trial) in the past 6 months (except for the NSCLC cohort).
16. Subjects who have not recovered from the effects of a major surgery.
17. Subject under guardianship, curatorship or safeguard of justice
