Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Approximately 21 eligible patients with advanced or metastatic solid tumors will be enrolled into two cohorts.
In the first cohort, nine (9) subjects will receive 1mg/kg of ipilimumab every 6 weeks and Nivolumab 3mg/kg every 2 weeks until disease progression or discontinuation due to toxicity or a maximum of 12 weeks.
The second cohort of twelve (12) subjects will receive 0.3mg/kg of ipilimumab every 6 weeks and Nivolumab 3mg/kg dosed every 2 weeks until disease progression or discontinuation due to toxicity or a maximum of 12 weeks.
Chort 1 and Cohort 2 will not be enrolled concurrently. Cohort 2 shall proceed after review of all Cohort 1 Day 8 data to identify if the study end point has been met.
Nivolumab & Ipilimumab are administered intravenously in clinic at the study sites under the review of study doctors and nurses to ensure this is correctly administered and to review for any adverse reaction. When administered in combination Nivolumab is infused first followed by Ipilimumab on the same day.

Timepoint [4] 336998 0
Safety will be evaluated for the duration of study participation, from baseline until end of treatment, defined as end of week 12 or 2 weeks post final dose of study drug.

Eligibility
Key inclusion criteria
1. Willing and able to give signed written informed consent.
2. Male or female subjects aged > 18 years.
3. Subjects must have a histologically or cytologically confirmed, metastatic or locally advanced solid tumor for which no standard therapy exists or standard therapy has failed.
4. Performance status score 0-1 (Eastern Cooperative Oncology Group Scale)
5. Estimated life expectancy > 3 months.
6. Subjects must have pretreatment clinical laboratory values meeting the following criteria during the Screening Phase (subjects may be retested during Screening Phase):
• Adequate hematological function defined by white blood cell count (WBC) > 3 x 109/L, absolute neutrophil count (ANC) > 1.5 x 109/L, lymphocyte count > 0.5 x 109/L, platelet count > 100 x 109/L, and hemoglobin > 9 g/dL (may be transfused). For subjects with gastric cancer only, acceptable parameters for WBC, ANC, and lymphocytes are as follows: WBC > 2 x 109/L, ANC > 1.0 x 109/L, and lymphocyte count > 0.5 x 109/L.
• Adequate hepatic function based by a total bilirubin level < 1.5 x the institutional upper limit of normal (IULN), and aspartate aminotransferase (AST) level < 2.5 x IULN, and an alanine aminotransferase (ALT) level < 2.5 x IULN. For subjects with documented metastatic disease to the liver, AST and ALT levels < 5 x IULN.
• Adequate renal function defined by an estimated clearance > 50 mL/min according to Cockcroft-Gault formula or measured 24-hour creatinine clearance (or local institutional standard method).
7. Effective contraception for both male and female subjects if risk of conception exists.
Note: Nivolumab and ipilimumab can cause fetal harm. Thus, women of childbearing potential and men must agree to use effective contraception, defined as 2 barrier methods, or 1 barrier method with an intrauterine device or use of oral female contraceptive. Subjects must confirm use of effective contraception at least 28 days before first study drug administration and for the duration of trial participation. Female subjects will be advised to maintain effective contraception for at least 5 months after the last treatment dose. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this trial, the treating physician should be informed immediately.

Key exclusion criteria
1. Prior therapy with any antibody/drug targeting T cell co-regulatory proteins (immune checkpoints), such as anti-PD-1, anti-PD-L1, or anti-cytotoxic T-lymphocyte antigen-4 (CTLA-4) antibody.
2. Concurrent anticancer treatment (e.g., cytoreductive therapy, radiotherapy except for palliative bone-directed radiotherapy, immune therapy, or cytokine therapy except for erythropoietin) within 21 days or 5x (five times) their half-lives (whichever is shorter) before the first dose of trial treatment; major surgery within 28 days before start of trial treatment (excluding prior diagnostic biopsy); or use of hormonal agents within 7 days before start of trial treatment, except for subjects with castration-resistant prostate cancer (CRPC), who may remain on treatment with luteinizing hormone–releasing hormone agonists or antagonists.
Note: Subjects receiving bisphosphonate or denosumab are eligible provided that treatment was initiated equal to 14 days before first dose of treatment.

15. All other significant diseases (e.g., inflammatory bowel disease) that, in the opinion of the investigator, might impair the subject’s tolerance of trial treatment.
16. Any psychiatric condition that would prohibit understanding or rendering of informed consent.
