Unfortunately, the addition of Nivolumab to the old standard of radiation and Temozolomide (without Optune) did not result in any improvement in survival or progression free survival. Strangely. we always assumed that patients using steroids would do worse but with both the Nivolumab group and the placebo group did a drop better than those without steroids. That doesn't mean steroids help - just that they do not hurt as much as we thought!
