Trial or other data
Nov 21New post hoc analysis of N-MOmentum PII/III pivotal trial has been published in Multiple Sclerosis and Related Disorders journal, showing that prior rituximab exposure did not impact the efficacy of Uplizna, and that Uplizna demonstrated comparable efficacy to trial participants without prior exposure to rituximab .
Sep 19PII/III N-MOmentum trial (NCT02200770; n=230) is published in the Lancet; it reports that compared with placebo, inebilizumab reduced the risk of a neuromyelitis optica spectrum disorder (NMOSD) attack; 21/174 (12%) of inebilizumab patients had an attack vs. 22 (39%) of 56 patients on placebo (HR 0.272, 95% CI 0.150–0.496; p<0.0001) .
Jan 19Positive topline results from the PIIb N-MOmentum trial (NCT02200770) reported. Pts on inebilizumab monotherapy saw a 77% decrease in the risk of developing NMOSD attack vs. those on placebo. Secondary analysis showed a decrease in worsening of disability in pts receiving the drug and safety and tolerability were acceptable and consistent with previous data. Full data are expected to be presented at the American Academy of Neurology meeting in May.
Oct 18Recruitment for NCT02200770 trial completed .
Jan 15Recruitment started for a multicentre, multinational, randomised double-blind PII/III trial (N-MOmentum; NCT02200770) with optional open-label period to evaluate the efficacy and safety of inebilizumab (MEDI-551) in adults with neuromyelitis optica or neuromyelitis optica spectrum disorders (NMO/NMOSD). Eligible subjects (n=252 planned) will first enter a randomised-controlled period (RCP) of up to 197 days where they will be randomised in a 3:1 ratio to receive either IV inebilizumab or placebo, with the primary outcome measure the time to onset of first NMO/NMOSD attack. Attacks will be evaluated by the investigator and confirmed against the attack criteria by an independent Adjudication Committee (AC). Subjects will then be given the option to enrol into an open label period of inebilizumab treatment for at least 12 months and maximum 3 years after the last subject has been enrolled. Any subjects discontinuing the trial at any point will enter a safety follow-up period of 12 months. Estimated primary completion date is Nov 2019 .
