Seres Therapeutics, Inc.

Research and Offices

Our corporate headquarters is located in Cambridge, Massachusetts, where we lease approximately 82,714 square feet of office, research, development, warehouse and laboratory space under a lease that expires in March 2033.

Clinical Manufacturing

We currently conduct our manufacturing operations in our leased facilities in Cambridge, Massachusetts, where we conduct process development, scale-up activities, the manufacture of active components for our biotherapeutic candidates, and quality control testing. We believe our current laboratory facilities and contract relationships are sufficient to meet our current bioprocess development and manufacturing needs. Product candidates may be brought into the facilities for economies of operation, or may remain external with contract manufacturing organizations, depending on business dynamics and development needs.

We plan to control the production of all products under current good manufacturing practices by making strategic investments in manufacturing, which may include collaborations with third parties, the design and renovation of existing facilities and the construction of additional new facilities for commercial supply.
