Not sure what you mean by validation

Tysabri's MoA, historical studies on JCV, and early data from patients on Tysabri, suggest association between JCV antibodies and PML but only the larger STRATIFY 2 study will confirm the correlation.

Perhaps the decision is not so horrible if you add switching to Gilenya as an option.
