Positives

Industry Context

This allows smaller companies to monetize their assets while larger companies expand their product portfolios.

Comparison to Industry Standards

• The licensing agreement between AnaptysBio and Vanda is similar to other deals in the biotech industry where smaller companies license their assets to larger pharmaceutical companies.
• For example, similar deals have been seen with companies like Galapagos and AbbVie, where Galapagos licensed their drug filgotinib to AbbVie for commercialization.
• The upfront payment and potential milestone payments are within the typical range for licensing agreements of this nature.
• The 10% royalty rate is also a common benchmark for pharmaceutical licensing deals.
• The Phase 3 results for imsidolimab, with 53% of patients achieving clear or almost clear skin at Week 4, are competitive with other treatments for GPP.

Stakeholder Impact

• Shareholders of AnaptysBio will benefit from the upfront payment, potential milestone payments, and royalties.
• Patients with GPP may have a new treatment option available.
• Vanda will expand its product portfolio and potentially increase its revenue.
• Employees of both companies may be impacted by the technology transfer and commercialization activities.

Next Steps
