Briefing
Merck signed a $22bn collaboration with Daiichi Sankyo for three antibody-drug conjugates, establishing the precedent that western large-cap pharma would pay large upfront sums for Asian biotech oncology pipelines. That deal set the structural template Pfizer is now following with Innovent, including milestone-heavy back-end economics.
AstraZeneca paid $1.35bn upfront to Daiichi Sankyo for Enhertu rights, an early example of western pharma licensing China-adjacent oncology assets at scale. The deal validated milestone-contingent structures where headline value dwarfs upfront payment, which is precisely the architecture Pfizer has adopted with Innovent.
A wave of western pharma licensing deals with Chinese biotechs in the late 2010s collapsed or were renegotiated when clinical data disappointed, training the market to apply a steep discount to headline milestone values. The Innovent deal's $10.5bn total versus $650m upfront ratio reflects that learned skepticism still embedded in how investors price these structures.

Eli Lilly's coordinated acquisition of three vaccine developers for up to $3.8bn last week signals large-cap pharma is simultaneously pursuing both licensing and outright acquisition to diversify pipelines, increasing competitive pressure on deal terms for biotech assets globally.

CVS restoring Zepbound coverage after Lilly cut price illustrates how pharma companies are increasingly accepting near-term revenue concessions to secure distribution access, a parallel dynamic to Pfizer accepting milestone-contingent rather than acquisition-price economics to secure Innovent's pipeline.
