Clinical Program and Material Developments
- The pediatric Phase III study will evaluate leniolisib’s safety, tolerability, and efficacy over an initial 12-week treatment period.
- Primary efficacy endpoints are reduction in index lymph node size and an increase in the proportion of naive B cells among total B cells from baseline at 12 weeks.
- Secondary endpoints include health-related quality-of-life measures covering physical, social, emotional, and school functioning.
- Eligible patients may continue receiving leniolisib for one year after the initial treatment period through an open-label extension.
- Pharming plans to initiate a similar trial in the third quarter of 2023 for children aged 1 to 6 years using a new pediatric formulation.
- The program is supported by positive Phase II/III results in patients aged 12 years and older, in which leniolisib met both co-primary endpoints versus placebo.
