Management Comments

• Our top priority is executing on our strategy to accelerate the development and delivery of transformative medicines for patients, and we are confident that we can accomplish this mission while being disciplined in our decision-making and responsible in our capital allocation, said Mina Kim, CEO of ACELYRIN.
• Given the capital intensity required to fully develop izokibep in multiple indications, we will consider all available options in our efforts to ensure its future success and to enable a successful development and commercialization path.

Industry Context

This announcement comes as the biopharmaceutical industry continues to focus on developing innovative treatments for autoimmune and inflammatory diseases. Acelyrin's pipeline, particularly izokibep and lonigutamab, targets significant unmet needs in these areas. The leadership changes and financial update are also relevant in the context of the competitive landscape and the need for efficient capital allocation in drug development.

Comparison to Industry Standards

• The reported positive results for lonigutamab in thyroid eye disease are comparable to intravenous approaches, suggesting a potential competitive advantage with its subcutaneous delivery.
• The Phase 2b/3 results for izokibep in psoriatic arthritis showed higher clinical responses than those reported by approved IL-17A agents and responses comparable to those reported by the IL-17A&F agents without evidence of the associated safety liabilities, indicating a potentially differentiated profile.
• The longer-term results for izokibep in hidradenitis suppurativa showed HiSCR100 was achieved earlier than reported by other IL-17A agents and the IL-17A&F agents, suggesting a potentially faster onset of action.

Management Changes

Stakeholder Impact

• Shareholders may react positively to the strong cash position and positive clinical trial results, but negatively to the CEO transition and potential challenges with izokibep.
• Employees may experience uncertainty due to the leadership changes.
• Patients may benefit from the potential development of new treatments for autoimmune and inflammatory diseases.
• Creditors and suppliers may view the company's financial stability positively.

Next Steps
