New Investment in Jade Biosciences, Inc.

RTW Biotech Opportunities Ltd (the "Company"), a London Stock Exchange-listed investment company focused on identifying transformative assets with high growth potential across the life sciences sector, is pleased to note the investment in new portfolio company, Jade Biosciences, Inc. ("Jade").

The Company, alongside other investment vehicles managed by RTW Investments, LP (the "Investment Manager"), participated in Jade's financing round that raised $80 million for its launch. The funding will be used to support Jade's plans to develop targeted therapies for indications with high unmet need across inflammation and immunology.

Jade Biosciences is developing a pipeline of potentially best-in-class therapies to redefine the standard of care for patients living with autoimmune conditions. Jade's pipeline of potentially best-in-class biologics was engineered by Paragon Therapeutics, which was founded by leading healthcare investor Fairmount. Jade is the fourth company founded from Paragon, which also includes Apogee Therapeutics, whose Series B the Company also invested in and continues to hold in its core public portfolio segment.

Josh Kennedy-Smith, Partner and Research Analyst at the Investment Manager said, "Jade Biosciences is an exciting new biotech developing best-in-class therapies for autoimmune diseases. We believe there is high potential and value in Jade's pipeline, which aims to address significant unmet medical needs in immunology and inflammation."
