Cosibelimab-ipdl is a human programmed death ligand-1 (PD-L1) blocking antibody. Cosibelimab-ipdl is a human IgG1 lambda monoclonal antibody. Cosibelimab-ipdl is produced in Chinese hamster ovary (CHO) cells and has a calculated molecular weight of approximately 147 kDa. UNLOXCYT (cosibelimab-ipdl) injection for intravenous use is a sterile, preservative-free, clear to opalescent, colorless to yellow or slightly brown solution. It is supplied in single-dose vials. Each vial contains 300 mg of UNLOXCYT in 5 mL of solution with a pH of 5.3. Each mL of solution contains 60 mg of cosibelimab-ipdl, acetic acid (0.24 mg), mannitol (37.35 mg), polysorbate 80 (1.1 mg), sodium acetate (1.31 mg), sodium chloride (4.09 mg), and Water for Injection, USP.
The recommended dosage of UNLOXCYT is 1,200 mg as an intravenous infusion over 60 minutes every 3 weeks. ( 2.1 ) 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 Adverse Reaction Severity Based on National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), Version 5. UNLOXCYT Dosage Modifications 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…
The following clinically significant adverse reactions are described elsewhere in the labeling: Severe and fatal immune-mediated adverse reactions [see Warnings and Precautions (5.1) ] Infusion-related reactions [see Warnings and Precautions (5.2) ] Complications of Allogeneic HSCT [see Warnings and Precautions (5.3) ] The most common adverse reactions (≥10%) were fatigue, musculoskeletal pain, rash, diarrhea, hypothyroidism, constipation, nausea, headache, pruritus, edema, localized infection, and urinary tract infection.

Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The pooled safety population described in WARNINGS AND PRECAUTIONS reflects exposure to UNLOXCYT as a single agent in 223 patients in two open-label, single-arm, multicohort studies, including 141 patients with advanced CSCC and 82 patients with other solid tumors and hematologic malignancies. UNLOXCYT was administered intravenously at doses of 800 mg every 2 weeks (n=174), 1,200 mg every 3 weeks (n=35), or…
Important safety information
Immune-Mediated Adverse Reactions ( 5.1 ) Immune-mediated adverse reactions can occur in any organ system or tissue, including the following: immune-mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis, immune-mediated endocrinopathies, immune-mediated dermatologic adverse reactions, immune-mediated nephritis and renal dysfunction, and solid organ transplant rejection. Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. Withhold or permanently discontinue UNLOXCYT based on the severity of reaction. ( 2.2 ) Infusion-Related Reactions: Interrupt, slow the rate of infusion, or permanently discontinue based on severity of reaction. ( 2.2 , 5.2 ) Complications of Allogeneic Hematopoietic Stem Cell Transplantation (HSCT): Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after being treated with a PD-1/PD-L1 blocking antibody. ( 5.3 ) Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception. ( 5.4 , 8.1 , 8.3 ) 5.1. Severe and Fatal Immune-Mediated Adverse Reactions UNLOXCYT is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death receptor-1 (PD-1) or PD-ligand 1 (PD-L1), blocking…
