Pangen was founded in 1999, listed on KOSDAQ in 2016, and became part of Huons Group in 2024 as a specialized biopharmaceutical company.
Its core business consists of sales of the erythropoietin (EPO) biosimilar Panpotin, used to treat anemia in chronic kidney disease patients, and biopharmaceutical contract development and manufacturing (CDMO).
Panpotin has obtained marketing approval in eight countries including Korea, Malaysia, the Philippines, Saudi Arabia, Turkey, Thailand, Brunei and Myanmar, is actually sold in six of them, and the company plans to expand exports further into Taiwan, Paraguay, Iraq and the Middle East, Africa and South America.
The CDMO segment secures revenue through intra-group collaboration, including production orders for human-derived hyaluronidase raw material from Huons Group affiliate Huons Lab.
In addition, using its own CHO-TECH cell line technology, Pangen is developing seven antibody biosimilars, including ipilimumab (Yervoy), guselkumab (Tremfya), romosozumab (Evenity), pembrolizumab (Keytruda), benralizumab (Fasenra), risankizumab (Skyrizi) and mepolizumab (Nucala), with three targeted for process development completion within the year.
In 2019 Pangen entered into an agreement with Samchundang Pharm to develop the cell line and process for a biosimilar of aflibercept (Eylea), a treatment for age-related macular degeneration, and holds a royalty structure tied to domestic and overseas sales, with royalties typically around 3 percent domestically and a combination of upfront payments and royalties overseas.
More recently, the company won a research services contract from the National Institute of Health under the Korea Disease Control and Prevention Agency to advance a non-clinical production system for an SFTS therapeutic antibody, expanding its research scope from biosimilars and CDMO into infectious disease antibody therapeutics.
Competitively, rather than directly rivaling large biosimilar makers such as Celltrion or Samsung Bioepis, Pangen positions itself as a smaller, specialized player focused on niche areas such as EPO finished-product exports to emerging markets and contract development services for affiliates and partners.
