Clinical summary

Summary

Eligible participants will be randomly allocated to one of two treatment arms.

In Arm A (Experimental), participants will receive V940 + pembrolizumab. Participants will receive up to 9 doses of V940 via an injection into the muscle (every 3 weeks) plus up to 9 doses of pembrolizumab via an intravenous (IV) infusion (once every 6 weeks).

In Arm B (Active Comparator), participants will receive placebo + pembrolizumab. Participants will receive up to 9 doses of a placebo via an injection into the muscle (every 3 weeks) plus up to 9 doses of pembrolizumab via an IV infusion (once every 6 weeks).

In both groups, treatment will be given until cancer recurrence or unacceptable toxicity, or for a total treatment duration of up to approximately 56 weeks, whichever is sooner.
