RTW Biotech Opportunities Ltd

Additional Investment in Numab Therapeutics

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 an additional investment in the Series C extension of Numab Therapeutics ("Numab"), a Swiss clinical stage biotech advancing a proprietary pipeline of multi-specific antibodies in immunology and oncology. 

Numab announced the completion of its CHF 50 million (~US$55m) Series C extension, in which the Company participated alongside other investment vehicles managed by RTW Investments, LP (the "Investment Manager"). The extension brought total Series C funding to CHF 180 million (~US$196m). The funds will be used to support the advancement of multiple potentially first-in-class and best-in-class programs into clinical development. The Company first invested in Numab's original Series C round in May of 2021.

Roderick Wong, Managing Partner and CIO at the Investment Manager said, "We are delighted to continue supporting Numab Therapeutics. Their innovative approach to developing multi-specific antibodies is particularly promising, and we believe that their groundbreaking research and development efforts hold great potential for transforming autoimmune and cancer treatments. Following J&J's announcement last summer to acquire Numab subsidiary, Yellow Jersey Therapeutics, we are optimistic that our continued partnership and this latest financing round will contribute to other significant advancements in immunology and oncology therapeutics."
