2 Resume LOQTORZI in patients with resolution to Grade 0-1 after corticosteroid taper. Permanently discontinue if not less than Grade 1 within 12 weeks of initiating steroids or inability to reduce prednisone to 10 mg per day or less (or equivalent) within 12 weeks of initiating steroids, or for endocrinopathies cannot be clinically stabilized on hormone replacement therapy.
All prescribers of LOQTORZI should inform patients about the patient card, explaining what to do should they experience any symptom of immune-related adverse reactions. The physician will provide the patient card to each patient.
No dose adjustment is recommended for patients who are aged 65 years or over (see section 5.2).
No dose adjustment is needed for patients with mild or moderate renal impairment. There are insufficient data in patients with severe renal impairment for dosing recommendations (see section 5.2).
No dose adjustment is recommended for patients with mild hepatic impairment. There are insufficient data in patients with moderate or severe hepatic impairment for dosing recommendations (see section 5.2).
The safety and efficacy of LOQTORZI in children and adolescents aged under 18 years have not been established. No data are available.
LOQTORZI is for intravenous use only and must be administered by infusion. The first infusion should be administered over 60 minutes via an infusion pump through an in-line filter (0.2 micron or 0.22 micron pore size). If no infusion-related reactions occurred during the first infusion, subsequent infusions may be administered over 30 minutes.
When administered on the same day as chemotherapy, LOQTORZI should be administered prior to chemotherapy through a different intravenous line.
For instructions on dilution of the medicinal product before administration, see section 6.6.
