Primary Outcome Measures	Measure Description	Time Frame
Changes in genomic and immune biomarkers that will be measured in the baseline biopsy and the first on-treatment biopsy by applying a log-transformation and the t-test.	If a departure from the normal distribution will be noticed for the distributions of the CD8 and CD4 then a log-transformation will be applied. The CD8 and CD4 will be compared between responders and non-responders by applying the t-test. Subgroup analysis based on the site will also be attempted.	3 years

Allowable: prior immune-oncology therapy, no maximal limit to the number of prior lines of systemic therapy for advanced or metastatic disease. All prior anti-neoplastic systemic therapy, including immune-oncology, must have a 4 week wash out period. There is no limit to the number of prior anti-neoplastic systemic treatments used before trial enrolment
Must have at least 1 tumor site that is amendable to tumor biopsy
Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained up to 4 weeks (28 days) prior to initiation of treatment on Day 1. Subjects for whom newly-obtained samples cannot be provided will not be eligible for this study. Subjects who have archival tissue available, not older than 6 months and with no intervening therapies from the day of the biopsy and the initiation of the study, will also be requested to also submit this sample, but are still required to undergo a pre-treatment biopsy.
Consent to provide archival tumor tissue for correlative biomarker studies
Must have at least 1 tumor site that is RECISTv1.1 measurable by CT or MRI scan. A previously irradiated lesion can be considered a target lesion if the lesion is well defined, measurable and there is objective evidence of progression following radiotherapy. The biopsy lesion cannot be the same as the target lesion
Life expectancy ≥ 16 weeks from proposed first dose date
Female subject of childbearing potential should have two negative pregnancy tests as verified by the investigator prior to starting any investigational product therapy: serum pregnancy test at screening and negative serum or urine pregnancy test on Cycle 1, Day 1 prior to treatment, and confirmed prior to each subsequent cycle of treatment.
