Why OSR?

OneSource Regulatory (OSR), is a specialized services firm that helps pharmaceutical companies successfully develop their regulatory strategy and develop Module 3 of the New Drug Application (NDA) and Biologics License Applications (BLA) for drug products and biologics respectively.

The OSR regulatory strategy staff can help you prepare for each regulatory milestone at each phase of development, including briefing package preparation, pre-Investigational New Drug Application (IND) preparation, and pre-NDA meeting preparation.

Our Chemistry, Manufacturing, and Controls (CMC) team members each have more than 25 years of regulatory experience, including formulation development, NDA/BLA CMC authoring, lab/manufacturing product and process development, and experience with biologics and small molecules. They also routinely interface with internal interdisciplinary teams (quality, clinical, operations) and health authorities. OSR supports activities from Phase 1 through post-approval.
