Management Comments

• We continued to meaningfully advance our wholly-owned and partnered programs across our protein dysregulation portfolio, highlighted by our ongoing clinical programs, as we continue to move closer to becoming a fully integrated commercial company.
• We look forward to multiple upcoming clinical milestones and program updates over the next 15 months from our wholly-owned programs, including topline data from the confirmatory Phase 3 AFFIRM-AL clinical trial for birtamimab, Phase 1 data on PRX012, and an update on timing of the Phase 1 program for PRX123.
• Our partnership with Bristol Myers Squibb achieved an important milestone in 2024, as BMS-986446, an anti-tau monoclonal antibody, began recruiting patients with early Alzheimers disease into a Phase 2 clinical trial.

Industry Context

Prothena's focus on protein dysregulation and its pipeline of investigational therapeutics aligns with the growing interest in developing treatments for neurodegenerative and rare amyloid diseases. The company's partnerships with major pharmaceutical companies like Bristol Myers Squibb, Roche, and Novo Nordisk highlight the industry's recognition of the potential of Prothena's approach.

Comparison to Industry Standards

• Prothena's Q1 2024 net loss of $72.2 million is higher than some of its peers in the biotechnology sector, such as Alnylam Pharmaceuticals which reported a net loss of $227.8 million in Q1 2024, but Alnylam has a much larger revenue base.
• The increase in R&D expenses is typical for a clinical-stage biotech company, as they invest heavily in clinical trials. For example, Biogen reported R&D expenses of $578.8 million in Q1 2024, but they are a much larger company with a broader portfolio.
• The cash position of $548.7 million is relatively strong for a company of Prothena's size, providing a runway for continued development. This is comparable to companies like Amylyx Pharmaceuticals, which had $369.5 million in cash and cash equivalents at the end of Q1 2024.
• The progress of Prothena's Alzheimer's disease programs, including PRX012, PRX123, and BMS-986446, is in line with the industry's focus on developing new treatments for this disease. Companies like Eli Lilly and Biogen are also heavily invested in Alzheimer's research.
• The development of birtamimab for AL amyloidosis is a significant step in addressing a rare and fatal disease, and Prothena's progress is being closely watched by the medical community.
