At this stage, the right data will show regulators and investors that your new molecule is effective and ready to progress. Therefore, access to focused support is critical to generating relevant data. Phase II is sometimes broken down further into Phase IIa and Phase IIb. During Phase IIa clinical trials, we are specifically focused on determining dosage requirements. A group of patients is administered the drug in various quanitites to investigate dosage and optimal frequency of doses. Phase IIb trials are specifically focused on testing the efficacy of the drug and determining how successful it is in terms of treatment, prevention, and diagnosing a disease. Our early product development team delivers Phase 2a clinical trials by offering the speed and dexterity of transnational medicine experts, while also being supported by a global scientific, regulatory, and clinical organization.
