Prothena: Despite Phase 3 Trial Failure, Other Neurodegenerative Programs In Place
Summary Prothena Corporation plc's phase 3 AFFIRM-AL trial for birtamimab in AL amyloidosis failed, leading to program termination and workforce reduction. Despite Phase 3 AL Amyloidosis trial failure, I maintain a Hold rating due to Prothena's robust pipeline, including Alzheimer's, Parkinson's, and ATTR-CM candidates. Key near-term catalysts include phase 1 PRX012 Alzheimer's data mid-2025 and other releases going forward, plus data updates for candidates prasinezumab and coramitug for PD and ATTR-CM. The Alzheimer's Disease market, in the 8 major markets [8MM] is expected to reach $19.3 billion by 2033; About between 5% to 6% of AD patients are early-symptomatic.

Prothena Corporation: Multiple Failures Make It Risky
Summary Prothena Corporation focuses on neurodegenerative diseases with a diverse pipeline, including Birtamimab for AL amyloidosis, which is in a phase 3 trial. Despite past trial failures, Birtamimab showed a survival benefit in severe AL amyloidosis patients, leading to a new phase 3 study. Financially, Prothena has a market cap of $850mn and a cash runway of 5-10 quarters, but is heavily spending on R&D. I recommend avoiding PRTA due to unpredictable upcoming data and past trial failures, making it risky and potentially un-investible. Read the full article on Seeking AlphaAnalyseartikel • Feb 22

Prothena Surges After Parkinson's Drug Misses Primary Endpoint
Summary Prothena's stock surged 34% despite Prasinezumab missing its Phase IIb primary endpoint, as Roche continues to invest. Prothena's pipeline includes multiple clinically staged drugs, with partnerships with major pharma companies, offering high-risk/high-reward potential. Investors should be cautious due to Prothena's 61% stock decline in 2024, but meaningful clinical success could create a buying opportunity. Prothena is rated as a HOLD, with upcoming catalysts in Parkinson's and Alzheimer's diseases that could fuel significant price appreciation.

Prothena: Delays And Data Uncertainty Undermine Case For Investing (Downgrade)
Summary Prothena Corporation plc's stock has dropped 67% since my last “Buy” rating, primarily due to delays and a lack of meaningful Phase 1 data for PRX012. PRX012, targeting amyloid beta for Alzheimer's, is Prothena's key value driver but remains in Phase 1, lagging competitors with similar drugs. Birtamimab's Phase 3 data has also faced delays, and while promising, it competes in a crowded market with limited patient populations. Despite a strong cash position, Prothena's pipeline progress and competitive landscape justify a downgrade to “Hold” until more substantial data is available.

Prothena: Potential For Future Price Drop On Failure Risk Of Late-Stage Trials
Summary Prothena Corporation is a late-stage biotech which specializes in proteinopathies and neurodegenerative diseases. They have a diverse pipeline. However, their main assets in attention currently are a first-in-class amyloid depleter, Birtamimab (wholly owned), and a Parkinson’s a-synuclein mAb, Prasinezumab (collab with Roche). Their revenue is primarily dependent on key milestone payments from collaborators. The stock has been dropping since its peak about a year ago, and I believe it still has room to drop for the foreseeable future due to the risk of failure of late-stage trials.
