Management Comments

• European KOL: 'The APRIL class will be the backbone [of therapy]. This class will become first-line.'
• US KOL: 'These therapies may change the thinking in IgAN. Instead of first starting with a hemodynamic agent and then going to prednisone now we would start with [anti-APRIL and anti-APRIL/BAFF].'
• US KOL: 'If I biopsy a patient and they have clear inflammation, if these were available, I would use them immediately with ACEi/ARBs.'

Industry Context

The announcement comes amid growing interest in targeted therapies for autoimmune diseases, particularly IgAN. The document highlights the limitations of current treatments and the potential for anti-APRIL therapies to address unmet needs. The merger positions the combined company to compete in the rapidly evolving market for autoimmune disease treatments.

Comparison to Industry Standards

• The document compares JADE-001 to other anti-APRIL therapies like sibeprenlimab and zigakibart, highlighting its potential for superior potency and half-life.
• It also compares JADE-001 to TACI-Fc therapies like atacicept and povetacicept, noting that anti-APRILs have shown comparable or better efficacy with reduced immunosuppression.
• The document references clinical trial data from various companies, including Chinook, Anthera, and ALPN, to support its claims about the efficacy of APRIL inhibition.
• The document notes that sibeprenlimab may be under-dosed in its ongoing Phase 3 trial, creating an opportunity for JADE-001 to demonstrate superior clinical activity.
• The document highlights that long-term BAFF inhibition can lead to significant B-cell depletion, while APRIL inhibition does not have the same effect.

Stakeholder Impact

• Shareholders of Aerovate and Jade will be impacted by the merger, with Jade shareholders receiving shares in the combined company.
• Patients with IgAN may benefit from the development of new and more effective therapies.
• Employees of both companies will be impacted by the merger, with potential changes in roles and responsibilities.
• The merger may impact the competitive landscape for autoimmune disease therapeutics.

Next Steps

• Complete the merger between Aerovate and Jade.
• Advance JADE-001 into Phase 1 clinical trials in healthy volunteers.
• Continue development of JADE-002 and JADE-003.
• Evaluate additional opportunities to build a pipeline of I&I therapies.
• File a registration statement on Form S-4 with the SEC.
