E.4 | Principal exclusion criteria |
1. Known hypersensitivity to any of the ingredients or excipients of the study drug.
2. Ongoing participation in any other therapeutic clinical trial.
3. Prior or ongoing medical condition (eg, concomitant illness, psychiatric condition, behavioral disorder, alcoholism, drug abuse), medical history, physical findings, ECG findings, or laboratory abnormality that, in the investigator's opinion, could adversely affect the safety of the patient, makes it unlikely that the course of treatment or follow-up would be completed, or could impair the assessment of study results. |
1. Ipersensibilità nota a uno dei principi attivi o degli eccipienti del farmaco in studio (Litesse® UltraTM [polidestrosio raffinato], polietilenglicole 3350, Lutrol® micro F127 [poloxamer 407], mannitolo 25C, crospovidone XL10, idrossietilcellulosa, vaniglia, Cab-O-Sil® M5P [silice colloidale], magnesio stearato).
