  • Daratumumab (Darzalex®) for multiple myeloma when ineligible for autologous stem cell transplantation
    • Approval is in combination with lenalidomide and dexamethasone for patients unable to pursue autologous stem cell transplantation. 
    • Common adverse events are infusion reactions, diarrhea, constipation, nausea, peripheral edema, fatigue, back pain, asthenia, pyrexia, upper-respiratory tract infection, and pneumonia. 
    • Recommended dose is 16 mg/kg, but the schedule varies throughout treatment. Refer to package insert for dosing details. Pre- and postinfusion medications are needed.

  • Pembrolizumab (Keytuda®) for metastatic small cell lung cancer
    • Approval is for patients with metastatic small cell lung cancer with disease progression on or after platinum-based chemotherapy and at least one other prior line of therapy. 
    • Adverse reactions include fatigue, decreased appetite, cough, nausea, and constipation. Immune related adverse events should be considered for all checkpoint inhibitors. 
    • Recommended dose is 200 mg via IV over 30 minutes every three weeks.

Renal Cell Carcinoma

  • Pembrolizumab (Keytuda®) plus axitinib (Inlyta®) for advanced renal cell carcinoma
    • Approval is for first-line treatment of advanced renal cell carcinoma that does not have to be PD-L1 positive. 
    • Common adverse events are hepatotoxicity, diarrhea, fatigue, hypertension, hypothyroidism, decreased appetite, and palmar-plantar erythrodysesthesia. Immune-related adverse events should be considered for all checkpoint inhibitors.
    • Recommended dosing is pembrolizumab 200 mg every three weeks and axtitinib 5 mg orally twice daily.
  • Avelumab (Bavencio®) plus axitinib (Inlyta®) for renal cell carcinoma
    • Approval is for first-line treatment of advanced renal cell carcinoma that does not have to be PD-L1 positive.
    • Common adverse events are diarrhea, fatigue, hypertension, musculoskeletal pain, nausea, mucositis, and palmar-plantar erythrodysesthesia. Immune-related adverse events should be considered for all checkpoint inhibitors.
    • Recommended dosing is avelumab 800 mg every two weeks and axitinib 5 mg orally twice daily.
