Date |
Amendment |
||
12 Oct 2018 |
Total urine collection from 0 to 8 hours for PK assessment in patients capable to control urination was added in appropriate sections, while the spot urine sample at 1 day after the injection was finally not collected. In addition, the collection of serious AEs was prolonged up to the last follow-up visit at day 90. |
||
19 Mar 2019 |
An additional cohort of 20 patients, receiving 0.05 mmol/kg of gadopiclenol, was included in order to assess the safety and urinary excretion of gadopiclenol and efficacy of gadopiclenol-enhanced MRI in children with pathologies of various body organs. This amendment was approved in Ukraine under the condition that no patients would be enrolled in the Body cohort in this country. |
||
24 Apr 2020 |
The main changes implemented in this amendment were the possibility to perform visits V3 and V4 remotely and additional on-site visits were scheduled at the latest 30 days and 120 days after gadopiclenol administration. Regarding the Body cohort, it was possible to shorten the 8-hour confinement period if it could not be respected and it was possible to perform the day 2 visit at patient’s home and remotely at the very least. This amendment was not submitted in Ukraine. |
