TP0502-Pharmaco-Scintigraphic-Study and Amendment

This is a Phase I, open-label, single-site trial to evaluate the drug release, using scintigraphic images and mesalazine plasma levels (PK) in healthy subjects and patients with mildly active UC. Overall, nine \[9\] subjects per prototype coating (a total of 18) will be evaluated. Four \[4\] healthy subjects and five \[5\] patients will be administered one \[1\] radio-labelled tablet of either formulation D or formulation E, respectively. Amendment: Overall, nine \[9\] subjects/patients will be evaluated. Four \[4\] healthy subjects and five \[5\] patients will be administered one \[1\] radio-labelled tablet of this new third improved formulation H. In order to keep the number of patients low, recruitment of patients will be stopped when obtaining at least 3 patients with evaluable scintigraphic images. Healthy volunteers will then be recruited to achieve a full set of participants (n=9 per Arm).
