Overview of the Seralutinib trials
The available trial data show that Seralutinib is being studied in people with pulmonary arterial hypertension, also called PAH.[1][2][3] The studies focus on long-term safety, tolerability, and treatment effect, especially on exercise capacity.[1][2]
Which condition is being studied
All three trials in the data study pulmonary arterial hypertension.[1][2][3] One trial describes the population as WHO Group 1 PH, which is a specific group within pulmonary hypertension classification.[3]
How the trials are designed
Two studies are phase 3 trials, and one study is a phase 2 trial.[1][2][3] The phase 3 study with ID NCT05934526 is randomized, double-blind, and placebo-controlled, which means people were assigned by chance to treatment groups, neither the participants nor the study team knew the assignments, and the study compared Seralutinib with placebo.[2]
The extension study NCT06274801 is an open-label extension study, which means everyone in the study knows which treatment is being given.[1] Its purpose is to evaluate long-term safety and efficacy in people with PAH.[1]
The phase 2 study NCT04816604 is an interventional study and also looks at long-term safety and tolerability in WHO Group 1 PH.[3]
What the trials measure
The main outcome in the extension study NCT06274801 is the incidence of treatment-emergent adverse events, which means health problems that begin after treatment starts.[1] This helps researchers watch for safety issues over time.[1]
The main outcome in the phase 3 placebo-controlled study NCT05934526 is the change in distance walked on the six-minute walk test from baseline to Week 24.[2] Baseline means the starting point before treatment begins.[2] This test is used to measure exercise capacity, or how much physical activity a person can do.[2]
The phase 2 study NCT04816604 also uses treatment-emergent adverse events as its primary outcome.[3] This shows that safety is a major focus across the studies.[1][3]
Who can take part
The trial data show that the studies include people with pulmonary arterial hypertension, and one study specifically includes subjects with WHO Group 1 PH.[1][3] One phase 3 study also evaluates Seralutinib when added to background PAH disease-specific medication, meaning participants were already receiving treatment for PAH.[2]
The available data do not list detailed age limits, sex limits, or other entry rules, so only the condition-based eligibility can be confirmed from the source material.[1][2][3]
Trial status and size
One phase 3 study, NCT05934526, is completed and enrolled 384 people.[2] The open-label extension study NCT06274801 is authorised and has an enrollment of 343 people.[1] The phase 2 study NCT04816604 is also authorised and enrolled 91 people.[3]
Key trial details
NCT06274801 is a phase 3 open-label extension study that looks at long-term safety and efficacy in pulmonary arterial hypertension.[1]
NCT05934526 is a phase 3 randomized, double-blind, placebo-controlled study that measures change in the six-minute walk test after 24 weeks.[2]
NCT04816604 is a phase 2 study in WHO Group 1 PH that focuses on long-term safety and tolerability.[3]
