                    May cause an infusion-related reactions; monitor for signs and symptoms of infusion-related reactions; interrupt, slow the rate of, or permanently discontinue tremelimumab; for Grade 1 or 2 infusion-related reactions, consider using premedications with subsequent doses

                    Based on findings from animal studies and its mechanism of action, fetal harm may occur when administered to pregnant females

                    Ocular side effects: May be associated with retinal detachment; various grades of visual impairment may occur; if events occur in combination with other immune-mediated adverse reactions, consider Vagt-Koyanagi-Harada-like syndrome; this may require treatment with systemic steroids to reduce risk of permanent vision loss

                    • Institute medical management promptly, including specialty consultation as appropriate
                    • Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy
                    • Immune-mediated adverse reactions include the following
                      • Colitis, pneumonitis, hepatitis, endocrinopathies (eg, adrenal sufficiency, hypophysitis, thyroiditis, hyperthyroidism, hypothyroidism, type 1 diabetes), nephritis with renal dysfunction, and/or dermatology reactions

                      • Hypophysitis can present with acute symptoms associated with mass effect (eg, headache, photophobia, visual field cuts); hypophysitis can cause hypopituitarism
                      • Thyroiditis can present with or without endocrinopathy; initiate hormone replacement therapy for hypothyroidism or institute medical management of hyperthyroidism as clinically indicated
                      • May cause hyperthyroidism and/or hypothyroidism
                      • Monitor for hyperglycemia or other signs and symptoms of diabetes; initiate treatment with insulin as clinically indicated
                      • Initiate symptomatic treatment including hormone replacement as clinically indicated

                    Pregnancy & Lactation

                    Pregnancy

                    Based on its mechanism of action, can cause fetal harm if administered to pregnant females

                    No data are available on use in pregnant females

                    Verify pregnancy status of females of reproductive potential prior to initiating treatment

                    Human immunoglobulin G1 (IgG1) is known to cross the placental barrier; therefore, tremelimumab and durvalumab has potential to be transmitted from mother to developing fetus

                    Animal data

                    • CTLA-4 blockade is associated with increased risk of immune-mediated rejection of developing fetus and fetal death

                    Contraception

                    • Females of reproductive potential: Use effective contraception during treatment and for 3 months after last dose

                    Lactation

                    There are no data on presence of tremelimumab in human milk, its effects on a breastfed child, or on milk production

                    Maternal IgG is known to be present in human milk

                    Effects of local gastrointestinal exposure and limited systemic exposure in breastfed child to tremelimumab are unknown

                    Advise females not to breastfeed during treatment and for 3 months after last dose

                    Pregnancy Categories

                    A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                    B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                    C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                    D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                    X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                    NA: Information not available.

                    Pharmacology

                    Mechanism of Action

                    Tremelimumab-actl, is a cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) blocking human IgG2monoclonal antibody, produced by recombinant DNA technology in NS0 cell suspension culture andhas a molecular weight of 149 kD

                    Monoclonal antibody binds to CTLA-4 and blocks the interaction with its ligands CD80 and CD86, releasing CTLA-4-mediated inhibition of T-cell activation
