Biotech IPOs Raise $700 Million, Led by MBX Biosciences, Bicara Therapeutics, and Zenas BioPharma

Key Points:
– MBX Biosciences raised $163.2 million, focusing on metabolic and endocrine disorders.
– Bicara Therapeutics and Zenas BioPharma raised $315M and $225M, respectively.
– These IPOs reflect renewed investor interest in biotech amid a sluggish broader market.

In a significant boost to the biotech IPO market, three emerging biotech companies—MBX Biosciences, Bicara Therapeutics, and Zenas BioPharma—collectively raised over $700 million through initial public offerings (IPOs). This surge in biotech IPOs, after a quiet summer, underscores the sector’s ability to attract investor attention despite broader market challenges.

MBX Biosciences successfully raised $163.2 million by pricing 10.2 million shares at $16 each, the high end of its expected range. MBX is developing peptide-based therapies for treating metabolic and endocrine disorders, including its lead candidate, MBX 2109, which targets chronic hypoparathyroidism. The company is also developing a preclinical therapy, MBX 4291, aimed at treating obesity by mimicking the effects of gut hormones GLP-1 and GIP. These advances in weight-loss therapies have garnered significant investor interest, especially as obesity treatments like Eli Lilly’s Zepbound and Novo Nordisk’s Wegovy continue to show potential for reducing risks such as stroke and heart attacks.

Another notable IPO, Bicara Therapeutics, raised $315 million, positioning itself as the third-largest biotech IPO of the year. Bicara is focused on developing bifunctional antibody drugs for treating cancers, including head and neck cancers. With plans to launch a late-stage trial alongside Merck’s Keytruda, Bicara is well-positioned to explore treatments for other solid tumors as well.

Zenas BioPharma raised $225 million through its IPO and is gaining traction in the immunology space. Zenas is developing a dual-targeting antibody currently in Phase 3 testing for treating IgG4-related diseases and anemia. With potential applications for multiple sclerosis and lupus, the company is riding a wave of enthusiasm for immune therapies, contributing to its successful public offering.

These IPOs reflect a growing interest in later-stage biotech companies, with all three firms advancing drugs already in human testing. The renewed confidence in the sector could also signal more biotech IPOs on the horizon, particularly as companies look to capitalize on robust investor demand for novel therapies in metabolic diseases, cancer, and immunology.

In a market that has been challenging for biotech firms, these successful IPOs highlight the resilience of companies with strong pipelines and innovative approaches to medical treatment. With MBX Biosciences set to trade under the symbol “MBX” on the Nasdaq Global Select Market, investors are closely watching the sector, hopeful that this uptick in activity is a sign of better things to come for biotech in 2025.
