MyThera's monthly GLP-1 candidate differentiated from weekly competitors (Lilly, Novo) and Phase 2 data confirmed monthly dosing feasibility, validating Pfizer's acquisition thesis to fill its obesity portfolio gap after internal programs failed on liver toxicity.
Pfizer invested $80B+ in acquisitions (led by Seagen for ADC tech and MyThera for obesity) while restructuring R&D to improve focus, raising phase 2 success rates from 20% to 50%+ and regulatory success to ~95%, positioning for sustained growth after COVID revenue dropped from $56B to $6B.
Seagen's antibody-drug conjugate (ADC) technology — four marketed products and 13 clinical programs — represents a 'precision missile' approach to cancer therapy that can target multiple tissues and payloads, making it one of Pfizer's most promising acquisitions if the platform delivers on its combinatorial potential.
