+Added: As a result, we consulted experts and decided to modify the starting dose regimen and the FDA agreed with our approach.
+Added: The most common adverse events continued to be local injection site reactions that are mostly mild, brief in duration and self-limited.
+Added: • In September 2025 we also announced that we amended the previous OLE study protocol (which had only included participants from previous clinical trials of nomlabofusp) to include adolescent and adult patients who have not previously participated in a prior nomlabofusp study and the study is now being referred to as the OL study.
+Added: In addition to risk mitigation measures against anaphylaxis that are already in place such as pre-medicating with antihistamines and supplying epinephrine auto-injectors to study participants, we introduced a new dosing regimen in which participants initially receive a 5 mg dose followed by a 25 mg dose one hour later under observation.
+Added: Nomlabofusp 25 mg is then administered once daily through day 30 and then the dose is increased to 50 mg once daily.
