Etude de phase I pour évaluer la faisabilité et la sécurité d’un transfert adoptif de lymphocytes T autologues infiltrant la tumeur en combinaison avec de l’IL-2 suivi d’un rattrapage avec Nivolumab chez des patients atteints d’un mélanome métastatique avancé

Other: TIL;Drug: Cyclophosphamide;Drug: Fludarabine;Drug: Interleukin-2;Drug: Nivolumab

Gender: All
Maximum age: N/A
Minimum age: 18 Years

Inclusion criteria:

1. Patient has provided informed consent to receive TIL-ACT treatment prior to initiation
of any study-specific activities/procedures.

2. Histologically confirmed diagnosis of melanoma.

3. Patients with unresectable locally advanced (stage IIIc) or metastatic (stage IV)
melanoma who have progressed on at least 1 standard first line therapy, including but
not limited to chemotherapy, B-Raf proto-oncogene, serine/threonine kinase (BRAF) and
Mitogen-Activated Protein Kinase/Extracellular signal-Regulated Kinase (MEK)
inhibitors, anti-Cytotoxic T-lymphocyte Associated 4 (CTLA4), anti-Programmed Cell
Death-1 (PD-1), anti-Programmed Cell Death Ligand-1 (PD-L1) or
anti-Lymphocyte-activation gene 3 (LAG3) antibodies and/or the combination.

4. Patients who have previously undergone tumor resection or biopsy and for whom pre-REP
TILs are already available and adequate for further REP expansion. The following
conditions have to be met:

? The CTE GMP Manufacturing facility / sponsor representative confirms that adequate
pre-REP material (in quantity and quality) is available to move to REP. In cases where
more than one collected material is available for a given patient, the CTE GMP
Manufacturing facility (in agreement with the sponsor) will decide which material will
be used for further expansion.

5. Male or female age = 18 to = 70 years at the time of informed consent. Patients aged
>70 will be evaluated by the investigator, and decision will be made according to
patient's status, upon agreement with the PI.

6. Clinical performance status of Eastern Cooperative Oncology Group (ECOG) of 0, 1 or 2

7. Life expectancy of greater than 12 weeks.

8. Radiologically measurable and clinically evaluable disease (as per RECIST v1.1).

9. At least one biopsiable metastatic lesion

10. In case of brain metastasis, patients must have three or fewer residual brain
metastases that are less than 1 cm in diameter and asymptomatic, provided that all
lesions have been adequately treated with stereotactic radiation therapy or gamma
knife therapy. Lesions should be stable for 1 month, as determined by CT or MRI
evaluation, after treatment and should not require steroids. Patients with surgically
resected brain metastasis are eligible independently of the size of the metastasis.

11. Serology:

- Seronegative for HIV infection (anti-HIV-1/-2)

- Seronegative for hepatitis B infection (HBs Ag, total anti-hemoglobin C (HBc),
anti-HBs). Patients with past or resolved hepatitis B infection (defined as
having a negative hepatitis B surface antigen HBsAg test and a positive anti-HBc
antibody test) are eligible, if hepatitis B virus (HBV) DNA test is negative.

- Seronegative for hepatitis C infection (anti-HCV): if a patient has positive
anti-HCV antibody, a negative hepatitis C virus (HCV) RNA need to be obtain to
register the patient.

12. Hematology

- Absolute neutrophil count = 1 x 10^9 cell/L without the support of granulocyte
colony stimulating factor (G-CSF).

- Platelet count = 100 x 10^9 cell/L

- Hemoglobin = 80 g/L. Subjects may be transfused to reach this cut-off.

13. Coagulation

- International normalization ratio (INR) or prothrombin time (PT) =1.5 times the
upper limit of normal (x ULN) unless the subject is receiving anticoagulant
therapy as long as PT and partial thromboplastin time (PTT) is within therapeutic
range of intended use of anticoagulants.

- PTT or activated PTT (aPTT) = 1.5 x ULN unless the subject is receiving
anticoagulant therapy as long as PT and PTT/aPTT is within therapeutic range of
intended use of anticoagulants.

14. Chemistry:

- Serum alanine aminotransferase (ALT)/ aspartate aminotransferase (AST) = to 3 x
ULN (even in case of liver metastasis).

- Total bilirubin =1.5 x ULN, except in patients with Gilbert's Syndrome who must
have a total bilirubin =2.5 x ULN

- Serum creatinine =1.5 x ULN or creatinine clearance by Cockcroft-Gault formula =
50 ml/min.

15. Adequate cardiovascular function, with documented left ventricular ejection fraction
(LVEF) = 45%

16. Adequate respiratory function with forced expiratory volume in 1 second (FEV1) = 65%
predicted, forced vital capacity (FVC) = than 65% predicted and diffusing capacity of
the lung for carbon monoxide (CO) (DLCO) = than 50% predicted corrected.

17. At the time the patient receives the preparative regimen (NMA chemotherapy), =21 days
must have elapsed from the time of any antibody therapy that could affect an
anti-cancer immune response, including but not limited to anti-CTLA4, anti-PD-1, PD-L1
or anti-LAG3 antibody therapy or their combination.

18. Patients' toxicities from previous treatments must have recovered to a grade 1 or less
according to NCI CTCAE 5.0, except for immune mediated-toxicities described below, as
long as they do not put at risk the patient's condition and do not require systemic
immunosuppressive steroids at immunosuppressive doses, including but not limited to:

- Alopecia

- Skin disorders

- Stable neuropathy

- Endocrinopathies requiring replacement treatment

Note: For other medical conditions, prior discussion and agreement with the Principal
Investigator is mandatory.

Note: Patients may have undergone minor surgical procedures within the past 3 weeks,
as long as all toxicities have recovered to grade 1 or less.

19. For women of childbearing potential (WOCBP: sexually mature women who have not
undergone a hysterectomy, have not been naturally post-menopausal for at least 12
consecutive months or have a serum follicle-stimulating hormone (FSH) < 40 mIU/ml
(milli international units/ml)):

- Agreement to follow instructions for contraception for the couple from screening
until month number 6 of the study, in case of women not receiving nivolumab; for
women receiving nivolumab, they are required to follow instructions for
contraception for the couple, during participation in the trial and for the 5
months after last nivolumab infusion.

- Negative pregnancy test (urine or serum) during screening.

20. For men participating in the trial and their female partners: agreement to follow
instructions for contraception for the couple from screening un
