Decrease dose routine in Sweden

The standard dose of nivolumab and ipilimumab is the one that’s accredited and established. As a result of in depth unwanted effects, Sweden has more and more begun to make use of a remedy routine with a decrease dose of ipilimumab, which is the most costly a part of this immunotherapy and causes essentially the most unwanted effects.
