  • Estimated primary completion date: May 27, 2023
  • The Phase 2 AMULET study is expected to be a biomarker supported proof-of-concept study (link)
☐ This study is designed to provide early readouts for the treatment effect on neurodegenerative processes using combined biomarkers and clinical outcome measures
☐ If results from this study are positive, then Lundbeck plans to initiate a Phase 3 study with Bayesian Response-adaptive treatment allocation
☐ Goal of Bayesian Response-adaptive treatment allocation is to increase number of patients assigned to more efficacious treatment arms
  • Lu AF82422 was granted Orphan drug designation for MSA by the EMA in April 2021 (link)

    [Results]<br>
    20211124: The biomarker supported Phase 2 AMULET study in MSA patients initiated in November 2021<br>
    20240201:<br>
    Lundbeck disclosed topline results of the Ph2 AMULET study for Lu AF82422 in MSA however detailed results were not released:<br>
    Primary endpoint (UMSARS Part I and II Total Score) did not meet statistical significance after 48 to 72 weeks of treatment.<br>
    Lundbeck emphasized a positive trend with Lu AF82422 treatment in slowing disease progression, with additional signals of efficacy across additional clinical and biomarker endpoints with innovative ways of approaching the readout, which they plan to discuss with regulators.<br>
    All study participants were eligible to roll-over to an ongoing OLE allowing Lundbeck to collect longer term data and enabling a "delayed start" analysis.<br>
    Lu AF82422 was generally well tolerated, no SAEs/TAEs were shared.<br>
    The company highlighted that the trial was designed to demonstrate Proof of Concept and the result were encouraging, justifying a more dedicated program towards registration. Trial size and duration to be determined following a complete analysis of the Ph 2 results.<br>
    Although Nfl was measured in this study, they did not collect this data in the observational TALISMAN study, &amp; therefore there is limited ability to establish its clinical meaningfulness at this time.<br>
    What's changed?<br>
    In November 2023, Lundbeck disclosed plans to initiate Ph3 in 2025, no additional information was shared regarding timelines during the January 31st investor call. We will continue to closely monitor the development plan following release of full Ph2 results and regulatory meetings<br>
    Questions/Answer Session:<br>
    What is the potential next development phase (i.e., another Ph2, Ph3, or accelerated approval): Lundbeck will seek input from regulators, and if in agreement, the next development step will be with the aim of registration of the product. Lundbeck did not rule out seeking a path to accelerated approval with regulators due to the high medical need.<br>
    Regarding the adequacy of the trial duration on treatment effect: Lundbeck suggested a 25% slowing of disease progression in 48 weeks (primary readout) across a larger sample would be sufficient to observe clinically and statistically meaningful differences. An OLE could be leveraged to demonstrate long term safety and efficacy.<br>
    "time wise, I think we did a really good study in terms of the primary readout (completion of 48 weeks on drug) and maybe allow people to go on a longer time."

Uncertain Spans

  • The right notes column for the Verdiperstat P2 row is rendered with line wraps that clip multiple words at the right edge (e.g. inhibition of [MPO]-induced pathological oxidative stress); the bracketed words have been reconstructed from the visible word fragments and the body context.
  • The Lu AF82422 right-column note received Orphan drug designation in Japan; is partially clipped at the right edge of the page; only received, designati..., and Japan; are unambiguously visible.
