Mavacamten, developed by Bristol-Myers Squibb in collaboration with MyoKardia (now part of Bristol-Myers Squibb), is a selective allosteric modulator of cardiac myosin approved by the U.S. Food and Drug Administration (FDA) in April 2022 for treating hypertrophic cardiomyopathy (HCM). The drug's supply chain involves multiple entities across manufacturing, raw material sourcing, and distribution channels.
Manufacturing and Supply Chain Overview
Primary Manufacturer: Bristol-Myers Squibb (BMS) oversees the global manufacturing processes for mavacamten.
Contract Manufacturing Organizations (CMOs): BMS utilizes specialized CMOs to produce active pharmaceutical ingredients (APIs) and finished product formulations.
Distribution Network: The drug is distributed internationally via BMS's medical supply chain, including third-party logistics providers (3PLs).

Raw Material Sourcing
BMS maintains confidentiality relating to the exact chemical suppliers of mavacamten's raw ingredients. However, the process involves multiple chemical intermediates, generally sourced from global bulk chemical suppliers specializing in pharmaceutical-grade compounds.
Manufacturing Locations
- BMS Plants: Manufacturing likely occurs at BMS's U.S. facilities or approved CMOs in North America or Europe.
- Third-party CMOs: Companies like Catalent, Thermo Fisher, and others may handle formulation, filling, and packaging processes.
Regulatory and Supply Chain Dynamics
- Regulatory Approvals: FDA approval in 2022 has driven demand, prompting BMS to scale manufacturing.
- Supply Chain Challenges: As with many biologic or specialized small-molecule drugs, supply chain disruptions can occur across raw materials, critical intermediates, or packaging components.
Competitive and Market Implications
The reliance on a limited number of manufacturing sites and suppliers creates potential vulnerabilities. Diversification of suppliers and geographic dispersion of manufacturing are strategic priorities for BMS to mitigate risks.
