Long-term efficacy| Lamzede® (velmanase alfa-tycv)

In the Trial 3 integrated analysis (N=33), investigators pooled the cumulative databases from Lamzede Phase I, II, and III trials in patients with alpha-mannosidosis^2,*

20 male and 13 female patients aged 6 to 35 years old (14 adults, 19 pediatric) received Lamzede weekly for a mean exposure of 89 weeks in adult patients and 155 weeks in pediatric patients
Overall mean exposure was 29.3 (15.2 SD) months

Phase I and II
(follow-up to 48 months)

Phase III
(active for 12-36 months)^†

Phase III (placebo for 12 months and then active to month 36)^‡

Phase I, II and III^§
(only 12 months data)

Lamzede delivers sustained results over time.²

*	The integrated study design was necessary to assess long-term efficacy and safety in a progressively worsening disease despite the rarity of patient population. Although the placebo-control period was limited to 12 months, duration of follow-up and repeated assessments were designed to mitigate that limitation. Additionally, while the mean and median durations of exposure exceed 2 years, only a small proportion of patients in the developmental program have non-missing efficacy measurements after 18 months. Therefore, the ability of the integrated analysis to provide interpretable evidence of long-term efficacy is unclear.
^†	One patient was originally in Phase I/II trials, but is only counted as part of Phase III.
^‡	One patient was in the placebo group of Phase III pivotal trial, and continued in both the compassionate use program and an extension trial. Patient data is only counted once.
^§	One patient was in the active Phase III pivotal trial, and continued in the compassionate use program, but did not participate in the long-term extension. Therefore, data represents 12 months.
