Date of Report: March 20, 2018
Event: Entry into a Material Definitive Agreement (Collaboration Agreement) and Share Subscription Agreement with Celgene Switzerland LLC.
Key Financial Metrics and Transaction Terms
This filing details a strategic collaboration rather than standard periodic financial results. Key financial terms include:
- Upfront Payment: $100 million payable by Celgene to Prothena.
- Equity Investment: Approximately $50 million to subscribe for 1,174,536 ordinary shares at $42.57 per share.

- Exercise Fees (Global Rights): Additional $55 million per program upon completion of Phase 1 clinical trials.
- Milestone Payments: Up to $562.5 million per program for regulatory and commercial milestones.
- Royalties: Tiered royalties ranging from high single-digit to high-teen percentages on net sales.
- Extension Fees: $10 million per 12-month period if Celgene extends the research term.
Material Changes and Strategic Developments
The primary material change is the establishment of a six-year collaboration framework covering three programs targeting Tau, TDP-43, and an undisclosed target. Key structural changes include:
- Licensing Structure: Celgene gains the right to exclusively license clinical candidates in the U.S. at IND filing, with an option to expand to global rights after Phase 1 completion.
- Decision Authority: Upon exercise of rights, Celgene assumes decision-making authority over development, regulatory, manufacturing, and commercialization activities.
- Capital Structure: Immediate dilution via the issuance of new shares to Celgene, subject to a 9.9% ownership cap and standstill restrictions.
Outlook, Risks, and Contingencies
Management Commentary: The company views the collaboration as a means to accelerate the delivery of a diversified pipeline of therapies and create significant value.
Forward-Looking Statements: The filing references potential disease-modifying approaches for Parkinson's disease (PRX002/RG7935) and anticipated timelines for NEOD001 studies and PRX004 advancement.
Risks and Contingencies:
- Termination Rights: Celgene may terminate the agreement at will on a program-by-program basis or in its entirety.
- Patent Challenges: Prothena may terminate the agreement if Celgene challenges a licensed patent.
- Uncertainty: Actual results may differ materially from projections due to risks described in the company's Form 10-K and 10-Q filings.
