NO

Mechanism of Action

Cemiplimab-rwlc is a recombinant human immunoglobulin G4 (IgG4) monoclonal antibody that binds to PD-1 and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response.

Libtayo Indications

Indications

Treatment of metastatic cutaneous squamous cell carcinoma (mCSCC) or locally advanced CSCC in patients who are not candidates for curative surgery or curative radiation. Treatment of locally advanced or metastatic basal cell carcinoma (laBCC or mBCC) in patients previously treated with a hedgehog pathway inhibitor or for whom a hedgehog pathway inhibitor is not appropriate.

Libtayo Dosage and Administration

Adult

Give by IV infusion over 30mins. 350mg every 3 weeks until disease progression, unacceptable toxicity, or up to 24 months. Dose modifications for adverse reactions: see full labeling.

Children

Not established.

Libtayo Warnings/Precautions

Warnings/Precautions

Severe and fatal immune-mediated adverse reactions can develop. Monitor closely for immune-related pneumonitis, hepatitis, colitis, endocrinopathies (thyroid disorders, adrenal insufficiency, diabetes, hypophysitis/hypopituitarism), nephritis/renal dysfunction, dermatologic reactions, myocarditis, neurological toxicities, others. Withhold or permanently discontinue based on severity and type of adverse reaction; see full labeling for management guidelines. Obtain liver enzymes, creatinine and thyroid function at baseline and periodically during therapy. Monitor for infection. Evaluate for Vogt-Koyanagi-Harada-like syndrome if uveitis in combination with other immune-mediated reactions occur. Interrupt, slow the infusion rate, or permanently discontinue based on severity of infusion-related reactions. Monitor closely for allogeneic HSCT-related complications (eg, graft-versus-host-disease, hepatic veno-occlusive disease, steroid-requiring febrile syndrome) and manage promptly. Embryo-fetal toxicity. Advise females of reproductive potential to use effective contraception during and for ≥4 months after the last dose. Pregnancy: exclude status prior to initiation. Nursing mothers: not recommended (during and for ≥4 months after the last dose).

Libtayo Indications

Indications

In combination with platinum-based chemotherapy for the first-line treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) in adults who are not candidates for surgical resection or definitive chemoradiation, with no EGFR, ALK or ROS1 aberrations. As a single agent for the first-line treatment of locally advanced or metastatic NSCLC in adults who are not candidates for surgical resection or definitive chemoradiation, and whose tumors have high-PD-L1 expression [Tumor Proportion Score (TPS) ≥50%] as determined by an FDA-approved test, with no EGFR, ALK or ROS1 aberrations.
