RTW Biotech Opportunities Ltd (the "Company"), the 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 announcement by Savara, Inc. ("Savara" Nasdaq: SVRA) that it has entered into a $75 million royalty funding agreement with funds managed by RTW Investments, LP.  RTW Bio will participate in this investment through its commitment to the RTW-managed 4010 Royalty Fund. Savara is a clinical stage biopharmaceutical company focused on rare respiratory diseases.

The funding is subject to FDA approval of Savara's lead program, MOLBREEVI, a treatment in Phase 3 development for autoimmune pulmonary alveolar proteinosis (autoimmune PAP), a rare disease characterised by the abnormal build-up of surfactant in the alveoli of the lungs. Assuming FDA approval, the funding will support the U.S. launch and further commercialisation of MOLBREEVI, which would be the first approved drug for autoimmune PAP.

Rod Wong, CIO of RTW Investments, said, "The pivotal clinical trial demonstrated the potential of MOLBREEVI to treat autoimmune PAP and this investment reflects our confidence in Savara and the strong commercial potential of the therapy. We are proud to partner with the Savara management team and look forward to supporting their efforts to bring this meaningful treatment to patients."
