Seqens offers complete and fully integrated R&D services to support your project from initial stage to commercial manufacturing in total compliance with the highest quality, safety and environmental standards.

complete and fully integrated R&D services

Seqens has a balanced portfolio of Big Pharma, mid-sized, specialty pharmaceutical and emerging pharmaceutical companies in the United States, Europe and Japan. We have the flexibility to scale up or down to meet the needs of any customer, whether:

  • An emerging pharmaceutical company that wants to develop a small molecule
  • A mid-sized company looking for a reliable partner to commercialize a Phase I or Phase II molecule and bring it to market or sell it to a Big Pharma company
  • A large pharmaceutical company that needs a partner with multi-site manufacturing capacity for all aspects of API development through Phase I, Phase II and Phase III, and the organizational capability for strong project management to ensure coordinated timelines and protocols and consistent quality

Seqens gives you the best of both worlds—a small, dedicated team, along with the support of a large corporation. The key to your success is our commitment to deliver best-in-class quality-by-design (QbD) methodologies, analytical evaluation, characterization and regulatory services.

Strong R&D capabilities to develop distinctive, cutom-made solutions, to speed up ours clients’ projects by adding value :

  • 3 state-of-the-art R&D center in Europe and the US
  • Our unique range of technologies enables us to manufacture complex molecules for small- and large-scale demands
