Immune-mediated adverse reactions have also occurred after the last dose of KEYTRUDA®. Immune-mediated adverse reactions affecting more than one body system can occur simultaneously.
  • For suspected immune-mediated adverse reactions, adequate evaluation to confirm aetiology or exclude other
    causes should be ensured. Based on the severity of the adverse reaction, KEYTRUDA® should be withheld and corticosteroids administered. Upon improvement to Grade ≤1, corticosteroid taper should be initiated and
    continued over at least 1 month. Based on limited data from clinical studies in patients whose immune-mediated adverse reactions could not be controlled with corticosteroid use, administration of other systemic immunosuppressants can be considered. KEYTRUDA® may be restarted within 12 weeks after last dose if the
    adverse reaction recovers to Grade ≤1 and corticosteroid dose has been reduced to ≤10 mg prednisone or equivalent per day.
  • No new serious treatment-related AEs were reported in ≥2 years.

  • KEYTRUDA® was associated with a higher incidence of serious AEs of any cause than placebo (20.7% vs 11.5%), as well as with a higher incidence of AEs of any grade (79.1% vs 53.0%) or of Grade 3 or 4 (18.6% vs 1.2%) that were considered by the investigator to be related to KEYTRUDA® or placebo.
  • No deaths were attributed to KEYTRUDA® or placebo.
  • The incidence of immune-mediated AEs and infusion reactions was consistent with previous reports: 36.7% (179
    participants) in the KEYTRUDA® arm vs 7.3% (36 participants) in the placebo arm.

Posology:

  • The recommended dose of KEYTRUDA in adults is either 200 mg every 3 weeks or 400 mg every 6 weeks administered as an intravenous infusion over 30 minutes.
  • The recommended dose of KEYTRUDA as monotherapy in paediatric patients aged 3 years and older with cHL or patients aged 12 years and older with melanoma is 2 mg/kg bodyweight (bw) (up to a maximum of 200 mg), every 3 weeks administered as an intravenous infusion over 30 minutes.
  • For use in combination, see the Summary of Product Characteristics (SmPC) for the concomitant therapies.
  • For urothelial carcinoma patients treated with KEYTRUDA in combination with enfortumab vedotin, administer KEYTRUDA after enfortumab vedotin when given on the same day.
  • For urothelial carcinoma patients treated with KEYTRUDA in combination with enfortumab vedotin, the recommended initial dose of enfortumab vedotin is 1.25 mg/kg (up to a maximum of 125 mg for patients ≥100 kg) as an intravenous solution on Days 1 and 8 of a 21-day cycle until disease progression or unacceptable toxicity.
  • Patients should be treated with KEYTRUDA until disease progression or unacceptable toxicity (and up to maximum duration of therapy if specified for an indication). Atypical responses (i.e. an initial transient increase in tumour size or small new lesions within the first few months followed by tumour shrinkage) have been observed. It is recommended to continue treatment for clinically stable patients with initial evidence of disease progression until disease progression is confirmed.
  • For the adjuvant treatment of melanoma, NSCLC, or RCC, KEYTRUDA should be administered until disease recurrence, unacceptable toxicity, or for a duration of up to one year.

Contraindications: Hypersensitivity to the active substance or to any of the excipients.

Precautions/Warnings: In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded. Women of childbearing potential should use effective contraception during treatment with pembrolizumab and for at least 4 months after the last dose of pembrolizumab. There are no data on the use of pembrolizumab in pregnant women. When assessing the PD-L1 status of the tumour, it is important that a well validated and robust methodology is chosen to minimise false negative or false positive determinations. KEYTRUDA can cause immune-mediated adverse reactions, including severe and fatal cases. Immune-mediated Pneumonitis, Immune-mediated Colitis, Immune-mediated Hepatitis, Immune-mediated Nephritis, Immune-mediated Endocrinopathies (as adrenal insufficiency, hypophysitis, type 1 diabetes mellitus, diabetic ketoacidosis, hypothyroidism, and hyperthyroidism) & Immune-mediated skin adverse reactions. KEYTRUDA can cause other immune-mediated adverse reactions as: uveitis, arthritis, myositis, myocarditis, pancreatitis, Guillain-Barré syndrome, myasthenic syndrome, haemolytic anaemia, sarcoidosis, encephalitis, myelitis, vasculitis, cholangitis sclerosing, gastritis, cystitis noninfective and hypoparathyroidism. KEYTRUDA can cause severe infusion-related reactions including hypersensitivity and anaphylaxis. Solid organ transplant rejection has been reported in the post-marketing setting in patients treated with PD-1 inhibitors. Cases of graft-versus-host-disease (GVHD) and hepatic veno-occlusive disease (VOD) have been observed in patients with cHL undergoing allogeneic HSCT after previous exposure to KEYTRUDA. In patients with a history of allogeneic HSCT, acute GVHD, including fatal GVHD, has been reported after treatment with KEYTRUDA. KEYTRUDA should not be used during pregnancy unless the clinical condition of the woman requires treatment with KEYTRUDA.
