Explanation
Given the prolonged half-life and delayed Tmax compared with preclinical data, the current design of the study, with PK sampling times stopping at t48h, did not make it possible to robustly capture the elimination kinetics of the compound.
Considering this PK profile identified during the cohort 1, it was decided to submit on 20 Jun 2025 an urgent safety measures (USM1/US-87471). The submission package included the Dose escalation meeting minutes and safety and PK data extracted from cohort 1 (please refer to USM1 supporting documents).
As requested by the French competent authorities after assessment of the mentionned USM, the subject inclusion of the cohort 2 was stopped on 23-JUN-2025 (and no administration performed) and a temporary halt is submitted.
Follow-up measures
On 23-JUN-2025, the Subject inclusion for cohort 2 was stopped and subjects were discharged from the clinical unit.
A MSA will be submitted and the study will be restarted only after reception of the final decision.
