Reason
Safety related (clinical or pre-clinical results)
Explanation
The temporary halt was implemented to allow amendment of the protocol following evaluation of dosimetry data from the first treated subject. The amendment is intended to modify the dose-escalation scheme and patient selection criteria, including use of a companion diagnostic approach, in order to deliver sufficient tumor radiation while minimizing exposure to critical and off-target organs and thereby improve the benefit–risk balance.
Follow-up measures
No further dosing or recruitment will occur during the temporary halt. Any protocol changes impacting subjects will be implemented only after approval of the planned substantial protocol amendment.
Benefit-risk balance changed
Yes
Treatment stopped
Yes
