SynAct Pharma AB (publ) (“SynAct”) today announced enrollment of the first patient to its clinical Phase 2b study EXPAND with the company’s candidate drug, AP1189, in patients with newly diagnosed severe rheumatoid arthritis (RA).
The EXPAND study, aimed at evaluating the safety and efficacy of SynAct Pharma´s lead compound, AP1189, is now initiated according to plan with recruitment of the first patient in Moldova. Enrollment in Bulgaria will be initiated imminently, following approval from local health authorities and ethical committee earlier this month.
“To initiate the EXPAND study, aimed to investigate the full treatment potential of AP1189, is a major milestone for the project. AP1189 addresses an unmet need for a novel treatment option in RA as the compound compared to most current treatment options is aimed to promote immunological resolution. A novel treatment concept that we foresee could have major impact on how to treat not only RA, but a large number of autoimmune and inflammatory diseases” said Jeppe Øvlesen, CEO. “The company is working hard to advance its pipeline and right now we are all focused on executing on our plan with primary focus on the development of AP1189.”
The aim of the study is to recruit and treat a total of 120 previous treatment naïve patients with severe RA with once daily dosing of 100 mg AP1189 or matched placebo for 12 weeks given in combination with standard therapy, methotrexate (MTX).
In the preceding BEGIN study, AP1189 was found to be safe and well tolerated and induce a statistically significant reduction in disease activity when given once daily for 4 weeks. EXPAND is designed to further evaluate the safety profile and the full treatment potential of the compound when given once daily with the newly developed immediate release tablet during a 12-week treatment period.
To strengthen the position of AP1189 as a novel compound with a unique mode of action in resolution of inflammation, several exploratory endpoints are included in EXPAND, such as MRI-scanning of affected joints, during the study. SynAct expects these data to be pivotal in the interactions with potential partners and for the further development of AP1189.
Key results will be available in the second half of 2023, subject to recruitment to the study being conducted as planned.
