UNLOXCYT Solution for injection Ref.[115485] Active ingredients: Cosibelimab

2.1. Recommended Dosage

The recommended dosage of UNLOXCYT is 1,200 mg administered as an intravenous infusion over 60 minutes every 3 weeks until disease progression or unacceptable toxicity.

2.2. Dose Modifications for Adverse Reactions

No dose reductions of UNLOXCYT are recommended. In general, withhold UNLOXCYT for severe (Grade 3) immune-mediated adverse reactions. Permanently discontinue UNLOXCYT for life-threatening (Grade 4) immune-mediated adverse reactions, recurrent severe (Grade 3) immune-mediated reactions that require systemic immunosuppressive treatment, or an inability to reduce corticosteroid dose to a prednisone equivalent of 10 mg or less per day within 12 weeks of initiating steroids.

Dosage modifications for UNLOXCYT for adverse reactions that require management different from these general guidelines are summarized in Table 1.

Table 1. Recommended Dose Modifications for Adverse Reactions:

ALT = alanine aminotransferase; AST = aspartate aminotransferase; DRESS: drug rash with eosinophilia and systemic symptoms; SJS: Stevens-Johnson Syndrome; TEN: toxic epidermal necrolysis; ULN: upper limit of normal.
^* Based on National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), Version 5.
^† Resume in patients with complete or partial resolution (Grade 0 to 1) after corticosteroid taper. Permanently discontinue if no complete or partial resolution within 12 weeks of initiating steroids or inability to reduce corticosteroid to a prednisone equivalent of 10 mg/day or less within 12 weeks of initiating steroids.
^‡ If AST and ALT are less than or equal to ULN at baseline in patients with liver involvement, withhold or permanently discontinue UNLOXCYT based on recommendations for hepatitis with no tumor involvement of the liver.
^§ Depending on clinical severity, consider withholding for Grade 2 endocrinopathy until symptom improvement with hormone replacement. Resume once acute symptoms have resolved.

2.3. Preparation and Administration

Visually inspect the vial for particulate matter and discoloration. UNLOXCYT is clear to opalescent, colorless to yellow or slightly brown. Discard the vial if visible particles are observed.

Do not shake the vial.

Preparation for Intravenous Infusion:

• Add 20 mL (1,200 mg) of UNLOXCYT to a 250 mL intravenous infusion bag containing 0.9% Sodium Chloride Injection. UNLOXCYT is compatible with an infusion bag made of polyolefin or polyvinyl chloride.
• Mix diluted solution by gentle inversion. Do not shake.

• At room temperature up to 25°C (77°F) for no more than 24 hours from the time of preparation until the end of infusion.
• Under refrigeration at 2°C to 8°C (36°F to 46°F) for no more than 24 hours from time of preparation until end of infusion. If refrigerated, allow the diluted solution to come to room temperature prior to administration.
• Discard after 24 hours.
• Do not freeze.

Administration:

• Visually inspect the infusion bag for particulate matter and discoloration prior to administration. Discard if the solution is discolored or contains particulate matter.
• Administer by intravenous infusion over 60 minutes through an intravenous line containing a sterile, in-line or add-on of 0.2-micron to 0.22-micron filter.
• Do not administer UNLOXCYT as an intravenous push or bolus injection.
