Adult dose

Dose: 840 mg every 2 weeks, or 1200 mg every 3 weeks, or 1680 mg every 4 weeks
Route: Intravenous infusion
Frequency: Every 2, 3 or 4 weeks depending on chosen regimen
Urothelial carcinoma (UC) monotherapy: 1L UC treated until disease progression or unmanageable toxicity; 2L UC treated until loss of clinical benefit or unmanageable toxicity. Must be initiated and supervised by physicians experienced in the treatment of cancer. Dose reductions are not recommended; manage immune-mediated adverse reactions by dose delay or discontinuation. If a planned dose is missed, administer as soon as possible and adjust the schedule to maintain the appropriate interval between doses.

Clinical monograph

How it works

It binds programmed death-ligand 1 (PD-L1), blocking its interaction with the PD-1 and B7.1 receptors and thereby restoring T-cell-mediated antitumour immune responses.

Prescribing in practice

  • Can cause severe and potentially fatal immune-mediated adverse reactions affecting almost any organ system (including pneumonitis, colitis, hepatitis and endocrinopathies), which may require corticosteroids and treatment interruption or discontinuation.
  • Infusion-related reactions can occur and patients should be observed during and after administration.
  • Prescribe and supervise only under specialist oncology direction with appropriate management protocols for immune-related toxicity.

Monitoring

Monitor liver function, thyroid and other endocrine function, and clinical signs or symptoms of immune-mediated reactions before and during treatment.

Counselling the patient

  • Report promptly any new breathlessness, cough, persistent diarrhoea, jaundice, severe fatigue or other unexplained symptoms.
  • Carry an alert card and tell any healthcare professional you are receiving immunotherapy.

Evidence & guidelines

Use is supported by clinical trial evidence and NICE technology appraisal guidance in defined urothelial and other cancer indications.
