June 24, 2026 – HighLight Pharma's JAK1/TYK2 inhibitor TLL-018 has been proposed for inclusion in the Breakthrough Therapy Designation (BTD) program for the treatment of rheumatoid arthritis.
Founded in 2017, HighLight Pharma focuses on developing innovative therapies for autoimmune and inflammatory diseases. Its lead asset, TLL-018, is a highly selective JAK1/TYK2 inhibitor. The drug is currently undergoing two pivotal Phase III registrational trials for chronic spontaneous urticaria (CSU) and rheumatoid arthritis (RA), both of which have met their primary endpoints. The company is also exploring multiple additional autoimmune indications. Its pipeline further includes TLL-041, a brain-penetrant JAK1/TYK2 inhibitor, as well as NLRP3 inhibitors and a highly selective brain-penetrant LRRK2 inhibitor.
Efung Capital participated in HighLight Pharma's financing rounds in 2020 and 2021. Looking ahead, Feng Capital will continue to deepen its dual-drive strategy of "industrial capital + professional empowerment," supporting HighLight Pharma in accelerating global multi-center clinical trials for core pipelines including TLL-041.
