Table 3 Investigational products in clinical research

From: How to achieve safe, high-quality clinical studies with non-Medicinal Investigational Products? A practical guideline by using intra-bronchial carbon nanoparticles as case study

- Investigational Medicinal Products (IMPs) are registered or non-registered medicines. New chemical entities, but also the medicinal product in the comparative study group and placebo’s of the challenging agents are encountered as IMPs.

- Non-Investigational Medicinal Products (non-IMPs) are medicines that are not the subject of investigation but supportive to the trial. These can include rescue medication, medicinal products given as standard care, or substances that are meant to induce a physiological response that is necessary to assess the pharmacological action of the IMP.
