Unresectable or metastatic, microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) solid tumors, as determined by an FDA-approved test, that have progressed following prior therapy and have no satisfactory alternative treatments. Unresectable or metastatic tumor mutational burden-high (TMB-H) [≥10 mutations/megabase] solid tumors, as determined by an FDA-approved test, that have progressed following prior therapy and have no satisfactory alternative treatments.

Limitations of Use:

The safety and efficacy in pediatrics with TMB-H CNS cancers have not been established.

Adult Dosage:

Give as IV infusion over 30mins. 200mg every 3 weeks or 400mg every 6 weeks until disease progression, unacceptable toxicity, or up to 24 months (in patients without disease progression). Dose modifications: see full labeling. Administer corticosteroids for most Grade ≥2 related immune-mediated reactions.

Children Dosage:

Give as IV infusion over 30mins. 2mg/kg (max 200mg) every 3 weeks until disease progression, unacceptable toxicity, or up to 24 months (in patients without disease progression). Dose modifications: see full labeling. Administer corticosteroids for most Grade ≥2 related immune-mediated reactions.

KEYTRUDA Warnings/Precautions:

Monitor for pneumonitis; withhold dose if Grade 2 pneumonitis; permanently discontinue if Grade 3 or 4, or recurrent Grade 2 develops. Monitor for colitis; withhold dose if Grade 2 or 3 colitis; permanently discontinue if Grade 4 develops. Monitor for hepatitis with or without liver tumor involvement; withhold dose or permanently discontinue based on severity of elevated liver enzymes. Monitor for nephritis with renal dysfunction; withhold dose if Grade 2 or 3 increased blood creatinine; permanently discontinue if Grade 4 develops. Monitor for endocrinopathies (adrenal insufficiency, hypophysitis, thyroid disorders, hyperglycemia or other diabetes symptoms); withhold or permanently discontinue if Grade 3 or 4 develops based on severity. Withhold dose if Grade 4 hematological toxicity in cHL or PMBCL patients develops until resolution to Grade 0 or 1. Monitor for immune-mediated rash or dermatitis; withhold if suspected SJS, TEN, or DRESS; permanently discontinue if confirmed. Permanently discontinue if any severe or Grade 3 immune-mediated adverse reaction recurs, for any life-threatening immune-mediated adverse reaction (except endocrinopathies controlled with hormone replacement or hematological toxicity in cHL or PMBCL patients), persistent Grade 2 or 3 reactions that do not recover to Grade 0–1 within 12wks after last dose, or inability to reduce corticosteroid dose to ≤10mg/day of prednisone or equivalent within 12wks. Monitor for infusion-related reactions; permanently discontinue if Grade 3 or 4 develops. Permanently discontinue if Grade 2, 3, or 4 myocarditis develops. Withhold if Grade 2 neurological toxicities develop; permanently discontinue if Grade 3 or 4 neurological toxicities develop. Monitor for allogeneic HSCT-related complications (eg, hyperacute, acute or chronic GVHD, steroid-requiring febrile syndrome, hepatic veno-occlusive disease) and manage promptly. Solid organ transplant recipients. Embryo-fetal toxicity. Advise females of reproductive potential to use highly 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).

KEYTRUDA Classification:

Programmed death receptor-1 (PD-1) blocking antibody.

KEYTRUDA Interactions:

Increased mortality when pembrolizumab is added to thalidomide analogue plus dexamethasone regimen in multiple myeloma: not recommended. Increased hepatotoxicity (in combination with axitinib); monitor liver enzymes more frequently.

Adverse Reactions:

Fatigue, musculoskeletal pain, decreased appetite, pruritus, diarrhea, nausea, rash, pyrexia, cough, dyspnea, constipation, pain, abdominal pain, hypothyroidism. In combination with chemotherapy: also asthenia, vomiting, alopecia, peripheral neuropathy, mucosal inflammation, stomatitis, headache, weight loss. In combination with axitinib: also hypertension, hepatotoxicity, palmar-plantar erythrodysesthesia, stomatitis, mucosal inflammation, dysphonia. In combination with lenvatinib: also hypertension, musculoskeletal disorders, vomiting, stomatitis, weight loss, palmar-plantar erythrodysesthesia, dysphonia, UTI, proteinuria, hemorrhagic events, acute kidney injury.

Drug Elimination:

Clearance (CV%): ~23% lower (geometric mean, 195 mL/day [40%]) at steady state vs that after the first dose (252 mL/day [37%]).
