Eligibility
Key inclusion criteria
I1. Male or female patients aged = 18 years at time of inform consent signature.

I2. Patient with histologically confirmed locally advanced / metastatic solid tumors of any histological types

I3. Patients treated with standard anti-PD-1/PD-L1 (e.g. pembrolizumab, atezolizumab, or any other ICI to be approved and reimbursed in France during the course of this trial, with a Q3W or Q6W schedule, either as monotherapy or in combination with chemotherapies according to their approved label). A positive list of eligible solid tumour types together with the associated anti-PD-1/PD-L1 standard therapy approved for each indication is provided in appendix 7. For any pathology not listed in this appendix but for which an anti-PD-1/PD-L1 has newly obtained a MA and is now reiumbursed in France, please refer to the section 1.6.2 of this protocol) and meet the following criteria :

* I3a. Cohort 1: Patient with RECIST 1.1.-defined SD under at least 12 weeks anti-PD-1/PD-L1. The initial evidence of SD is to be confirmed by a second assessment, no less than 4 weeks from the date of the first documented SD.
* I3b. Cohort 2: Patient with RECIST 1.1-defined PD under anti-PD-1/PD-L1.
* I3c. Cohort 3: Patients with RECIST 1.1-defined PD under anti-PD1/PD-L1 after initial objective response (CR or PR according to RECIST V1.1)

Note 1 : For patients treated with an anti-PD-1/ PD-L1 previously combined to another anti-cancer agents of any type (including but not limited to chemotherapy/ other immunotherapy/ biological -or targeted agents) theseagents must be stopped 2 weeks or 5* t ½ whichever is shorter before C1D1 while anti-PD1 or anti PDL1 is continued according to Market Authorisation.

Note 2: Patients may have received a line of chemotherapy or any other standard anti-cancer agent after PD under anti-PD-1/PD-L1 but recurrence/progression under aPD-1/aPD-L1 y must have been documented = 12 months before inclusion. Intercurrent chemotherapy or other standard agents must be stopped 2 weeks or 5* t ½ whichever is shorter before C1D1. Those patients will be then recruited in one of the refractory cohorts and could re-start an anti-PD1/PD-PL1 immediately in combination with NP137 at inclusion.

I4. Refractory cohorts: To be eligible in these cohorts, patients must meet all the following criteria:

* Evidence of clinical benefit according to investigator assessment. The assessment of clinical benefit should be balanced by clinical judgment as to whether the patient is clinically deteriorating and unlikely to receive any benefit from continued ICI treatment.
* Absence of symptoms and signs (including laboratory values, such as new or worsening hypercalcemia) indicating unequivocal progression of disease,
* Absence of decline in ECOG PS that can be attributed to disease progression,
* Absence of tumor progression at critical anatomical sites (e.g., leptomeningeal disease) that cannot be managed by protocol-allowed medical interventions.
* No ongoing clinically significant AE related to ICI.

I5. Patient with of at least one lesion measurable and evaluable as per RECIST V1.1 according to central imaging review before C1D1. Tumour lesions located in a previously irradiated area, or in an area subjected to other locoregional therapy, cannot be considered as measurable/evlaluable unless there has been a documentation of progression in the lesion.

I6. Availability of a representative archival tumor sample in formalin-fixed paraffin embedded (FFPE) block (primary tumor or metastasis) or newly obtained core or excisional biopsy of a tumor lesion together with an associated pathology report.

I7. Presence of at least one tumor lesion with a diameter =10 mm (=20mm in case of a single biospsiable and RECIST 1.1 target lesion) visible by medical imaging and accessible to repeatable percutaneous sampling that permits core needle biopsy without unacceptable risk of a significant procedural complications, and suitable for retrieval of 4 cores using a 16-gauge diameter needle or larger.

Note: lesions to be biopsied should not be selected as RECIST target lesions unless there are no other lesions suitable for biopsy. If a RECIST target lesion is used for biopsy, the lesion must be = 2 cm in longest diameter. Bone lesions are not adequate lesions for biopsies. Osteolytic lesions with soft tissue involvement cannot be biopsied.

I8. Life expectancy = 3 months. I9. Eastern Cooperative Oncology Group performance status 0 or 1

I10. Demonstrate adequate cardiovascular function:

* QTcF < 470ms
* Resting BP systolic < 160mmHg and diastolic < 100mmHg
* LVEF > 50% as determined by transthoracic echocardiogram.

I11. Demonstrate adequate organ function as defined in table below, all screening laboratory tests should be performed within 7 days prior C1D1:

- Hematological : Absolute neutrophil count (ANC) = 1.5 G/L (1500/µL)

Platelets = 100 G/L (100000/µL) (transfusion within 21 days before C1D1 is allowed).

Hemoglobin = 9 g/dL or = 5.6 mmol/L-1 Packed red blood cell(pRBC) transfusion is allowed within past 2 weeks. Patient can be on stable dose of erythropoietin (=3 months)

- Renal : Serum creatinine OR Creatinine clearance according to CKD-EPI (Appendix 3) = 1.5 X upper limit of normal (ULN) OR = 30 mL/min/1.73m2 for patient with creatinine levels > 1.5 ULN

- Hepatic : Serum total bilirubin = 1.5 X ULN OR Direct bilirubin = ULN for patients with total bilirubin levels > 1.5 ULN

AST and ALT = 2.5 X ULN (up to 5 ULN in case of liver metastases)

- Coagulation : International Normalized Ratio (INR) and Activated Partial Thromboplastin Time (aPTT) = 1.5 X ULN Note: This is applicable only for patients not receiving an anticoagulant treatment: patients receiving therapeutic anticoagulation must be on stable dose.

I12. Women of child-bearing potential must have a negative urine pregnancy test at screening (within 72 hours prior C1D1) and must agree to use 2 effective forms of contraception from the time of the treatment period and of the negative pregnancy test up 6 months after the end of their treatment. Effective forms of contraception are listing in Appendix 4.

I13. Fertile males must use a highly effective contraception during dosing period and through 3 months after final dose of study treatments.
