programmed death-1 inhibitors
- Metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC in patients who are not candidates for curative surgery or curative radiation.
- Locally advanced basal cell carcinoma (BCC) in patients previously treated with a hedgehog pathway inhibitor or for whom a hedgehog pathway inhibitor is not appropriate.
- Metastatic BCC in patients previously treated with a hedgehog pathway inhibitor or for whom a hedgehog pathway inhibitor is not appropriate.
- First-line treatment of non-small cell lung cancer (NSCLC) in patients whose tumors have high PD-L1 expression [Tumor Proportion Score (TPS) ≥ 50%] (but no EGFR, ALK or ROS1 aberrations), and is locally advanced where patients are not candidates for surgical resection or definitive chemoradiation or is metastatic.
Programmed death receptor-1 (PD-1) blocking antibody (an IgG4 kappa immunoglobulin) that binds to PD-1 and blocks its interaction with its ligands, PD-L1 and PD-L2, resulting in activationactivation of the immune system and decreased tumor growth.
- Decreased progression of metastatic or locally advanced CSCC or BCC.
- Improved survival in NSCLC.

Monitor for signs and symptoms of immune-mediated pneumonitis (new or worsening cough, chest pain, shortness of breath) periodically during therapy. For Grade 2 reactions, hold cemiplimab. For Grade 3 or 4 reactions, permanently discontinue cemiplimab. Systemic corticosteroids have been used for treatment.
Monitor for signs and symptoms of immune mediated colitis (diarrhea, blood or mucus in stools, severe abdominal pain) periodically during therapy. For Grade 2 or 3 colitis, hold cemiplimab. For Grade 4, discontinue cemiplimab permanently. Treat with systemic corticosteroids.
Monitor for immune-mediated endocrinopathies (adrenal insufficiency, hypophysitis, hypothyroidism, hyperthyroidism, Type 1 diabetes mellitus). May cause primary or secondary adrenal insufficiency. For ≥Grade 2 adrenal insufficiency, start symptomatic treatment, including hormone replacement, as indicated. If symptoms of immune-mediated hypophysitis (headache, photophobia, visual field defects) occur, begin hormone replacement therapy. If symptoms of immune-mediated thyroiditis (hyperthyroidism, may be followed by hypothyroidism) occur, begin hormone replacement or medical management of hyperthyroidism as indicated. If symptoms of hyperglycemia or other signs and symptoms of diabetes occur, begin insulin therapy as indicated. If endocrinopathies of Grades 3 or 4 occur, permanently discontinue cemiplimab.
Monitor for signs and symptoms of immune-mediated skin reactions (rash, pruritus, blistering, painful sores in mouth, nose, throat, genital area) periodically during therapy. Topical emollients and/or topical corticosteroids may treat mild to moderate non-exfoliative rashes. May cause exfoliative dermatitis (SJS, TEN, DRESS). If SJS, TEN, or DRESS is suspected, hold cemiplimab. If SJS, TEN, or DRESS are confirmed, permanently discontinue cemiplimab.
- Monitor for signs and symptoms of myocarditis (chest pain, irregular heartbeat, shortness of breath, swelling of ankles) during therapy. If Grade 2, 3, or 4 myocarditis occur, discontinue cemiplimab permanently.
- Monitor for signs and symptoms of neurological toxicities (confusion, sleepiness, memory problems, changes in mood or behavior, stiff neck, balance problems, tingling or numbness of the arms or legs) during therapy. If Grade 2 neurological toxicities occur, hold cemiplimab. If Grades 3 or 4 occur, permanently discontinue cemiplimab.
Monitor for signs and symptoms of infusion-related reactions (chills or shaking, itching or rash, flushing, shortness of breath, wheezing, dizziness, fever, feeling faint, back or neck pain, facial swelling) during therapy. If Grade 1 or 2 reactions occur, Interrupt of slow rate of infusion. If Grade 3 or 4 reactions occur, Permanently discontinue cemiplimab.
Lab Test Considerations:
Verify negative pregnancy test before starting therapy.
- Patient selection with locally advanced or metastatic NSCLC is based on PD-L1 expression on tumor cells. Information on FDA-approved tests for the detection of PD-L1 expression is available at: http://www.fda.gov/CompanionDiagnostics.
- Monitor liver and thyroid function tests at baseline and periodically during therapy. If AST or ALT ↑ to ≥3 and ≤ 8 times the upper limit of normal (ULN) or if total bilirubin ↑ to ≤3 times ULN, hold cemiplimab. If AST or ALT ↑ to >10 times ULN or total bilirubin ↑ to >1.5 and ≤ 3 times the ULN, permanently discontinue cemiplimab. Administer systemic corticosteroids to treat. For patients with hepatitis with tumor involvement of the liver, if baseline AST or ALT >1 and ≤3 times ULN and increases to >5 and ≤10 times ULN or baseline AST or ALT >3 and ≤5 times ULN and increases to >8 and ≤10 times ULN, hold cemiplimab. If AST or ALT increases to >10 times ULN or total bilirubin increases to >3 times ULN, permanently discontinue cemiplimab.
- Monitor for signs and symptoms of nephritis. If Grade 2 or 3 increased serum creatinine occurs, hold cemiplimab. If Grade 4 increased serum creatinine occurs, permanently discontinue cemiplimab.
- May cause increased INR, lymphopenia, anemia, hyponatremia, hypophosphatemia, and hypercalcemia.

- Rep: May be teratogenic. Advise females of reproductive potential to use effective contraception and avoid breastfeeding during and for at least 4 mo after last dose. Advise patient to notify health care professional promptly if pregnancy is suspected.
