    CONTINUATION OF ICI TREATMENT: Patients receive either pembrolizumab intravenously (IV) over 30 minutes on day 1, nivolumab IV over 30 minutes on days 1 and 15, atezolizumab IV over 30-60 minutes on day 1, durvalumab IV over 60 minutes on days 1 and 15, or avelumab IV over 60 minutes on days 1 and 15. Cycles repeat every 21 or 42 days for pembrolizumab, every 21 days for atezolizumab, and 28 days for nivolumab, durvalumab, and avelumab in the absence of disease progression or unacceptable toxicity.

    DISCONTINUATION OF ICI TREATMENT: Patients receiving ICI treatment will discontinue ICI treatment within 1 cycle length after randomization. Cycle length is determined by the ICI regimen the patient is receiving at randomization. At disease progression patients may restart the same ICI treatment they were receiving upon randomization at physician discretion.
