Evidence outlook · results not reported
LUMA (NCT05348785) · Parkinson Disease
The lead study's design has limits that temper confidence (see the rationale below), and its results have not been reported. This tier describes the design, not an outcome.
LUMA (NCT05348785): The study randomized 650 participants to BIIB122 or matching placebo, with participants, care providers, investigators, and outcome assessors blinded. Its primary endpoint is time to confirmed worsening on the clinical MDS-UPDRS motor and daily-living scale, but the comparison has not been reported, so the trial provides well-designed evidence with an unknown result rather than evidence of a demonstrated benefit.
