Phase 2 vs Phase 3 — Neurology Deal Valuation Comparison

Phase 2 deals are more milestone-weighted (89% milestones), reflecting higher clinical risk. Phase 3 deals shift toward higher upfront allocations (19% upfront) as clinical de-risking reduces the need for contingent milestone structures.

The optimal licensing window depends on strategic priorities. Phase 2 assets offer lower entry cost for licensees, while Phase 3 assets provide more certainty. The 33% premium from Phase 2 to Phase 3 reflects the value created by clinical data, making the transition point critical for deal timing.
