Immunotherapy by Nivolumab for HIV+ Patients

Inclusion criteria

• Age ≥ 18 years old
• HIV1 or HIV2, regardless of CD4 cell count
• HIV Viral load <200 copies/mL
• Proven histologically and/or cytologically, stage IIIB-IV or metastatic relapse post-surgery non-small cell lung cancer (NSCLC)
• Disease recurrence or progression during/after at least one prior platinum doublet-based chemotherapy regimen for advanced or metastatic disease
• Measurable disease by Computed tomography (CT)/Magnetic resonance imaging (MRI) per RECIST 1.1 criteria
• Performance status (PS) 0, 1 or 2
• Written informed consent
• Patients must have adequate organ function: creatinine clearance > 40 mL/min (Cockcroft, MDRD or CKD-Epi formula or 24h Urine Calculate creatinine clearance from a 24h urine collection ), neutrophiles count > 1500/mm3; platelets > 100 000/mm3 ; hemoglobin > 9 g/dL; hepatic enzymes < 3N with total bilirubin ≤ 1.5 × ULN (upper limit of normal) except subjects with documented Gilbert's syndrome (≤ 5 × ULN) or liver metastasis, who must have a baseline total bilirubin ≤ 3.0 mg/dL
• Patients must receive appropriate care and treatment for HIV infection including ART when clinically indicated and subjects should be under the care of a physician experienced in HIV management. In case of recent introduction of cART and CD4 levels <50 cells/ml, inclusion will be possible provided subjects had at least 4 weeks of treatment prior to inclusion, to avoid clinical type IRIS (immune inflammatory syndrome reconstitution). All antiretroviral treatments are allowed.
• Females of childbearing potential who are sexually active with a nonsterilized male partner must use a highly effective method of contraception for 28 days prior to the first dose of investigational product, and must agree to continue using such precautions for 6 months after the final dose of investigational product; cessation of contraception after this point should be discussed with the referent physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. They must also refrain from egg cell donation for 6 months after the final dose of investigational product. Men receiving nivolumab and who are sexually active with women of childbearing potential will be instructed to adhere to contraception (appendix I) for a period of 31 weeks after the last dose of nivolumab.
• Persons deprived of liberty could be eligible because the expected benefice (improvement of disease control rate) justifies the foreseeable risk (adverse reaction of nivolumab).

Exclusion criteria

• Concurrent malignancies requiring active intervention
• Active Infection
• Patient with known EGFR activating tumor mutation or known ALK or ROS1 gene rearrangement not treated with the appropriate targeted therapy.
• History of immunological events related to HIV: lymphoid interstitial pneumonitis (LIP), non-infectious uveitis, encephalitis and other manifestations of CD8 lymphocyte infiltration syndrome, HIV-associated nephropathy (HIVAN).
• Subjects with active, known or suspected autoimmune disease. Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune thyroiditis only requiring hormone replacement, or conditions not expected to recur in the absence of an external trigger are permitted to enroll.
• Active or history of inflammatory bowel disease (eg, diverticulitis, colitis, Crohn's, coeliac disease or other serious gastrointestinal chronic conditions associated with diarrhea). Note that diverticulosis is permitted.
• Symptomatic cerebral metastasis unless treated by brain radiotherapy which will be completed for at least 15 days before the beginning of the treatment; subjects with carcinomatous meningitis.
• Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways.
• The last dose of prior chemotherapy or radiation therapy (with the exception of palliative radiotherapy) was received less than 3 weeks prior to inclusion;
• History of primary immunodeficiency, history of organ transplant that requires therapeutic immunosuppression and the use of immunosuppressive agents within 28 days of inclusion or a prior history of severe (grade 3 or 4) immune mediated toxicity from other immune therapy.
• Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of inclusion. Intranasal/inhaled or topical steroids, and adrenal replacement steroid doses ≤ 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease.
• Female subjects who are pregnant, breast-feeding or male or female patients of reproductive potential who are not employing an effective method of birth control.
• Legally protected adults.
