This applies from inclusion in the study and for the duration of treatment with Ipilimumab, Relatlimab and Nivolumab plus 5 half-lives of study treatment plus 30 days (duration of ovulatory cycle) for a total of 24 weeks post-treatment completion. The following are considered safe methods of contraception:

    * Intrauterine device
    * Surgical sterilization
    * Surgical sterilization of male partner with verification of no sperm after the procedure
    * Menopause (for more than 12 months)

Exclusion Criteria:

Patients will be excluded if they meet one of the criteria's listed below

2. Known hypersensitivity to one of the active drugs or one or more of the excipients.
3. Severe medical conditions, such as severe asthma/COLD, significant cardiac disease, poorly regulated insulin dependent diabetes mellitus among others.
4. Creatinine clearance \< 70 ml/min (1).

14. Simultaneous treatment with other systemic anti-cancer treatments.
15. Patients with active and uncontrollable hypercalcemia

(1)In selected cases it can be decided to include a patient with a GFR \< 70 ml/min with the use of a reduced dose of chemotherapy.

(2)In selected cases a systemic dose of ≤10 mg prednisolone or a transient planned treatment that can be stopped before TIL therapy can be tolerated.
