A majority of the U.S. Food and Drug Administration (FDA) approvals for cancer agents in the latter part of 2018 represented second and third approvals for new indications in other disease sites. Many were given expedited approval, but with that comes the potential that the incidence of adverse events may be underrepresented because fewer patients received the agents in a clinical trial setting.
Nurses are critical in sharing the adverse events observed when caring for patients on new agents. Through ONS’s Recognize It; Report It campaign, nurses can understand how to report adverse events to providers for appropriate management and to FDA for widespread dissemination to prescribers and practitioners.

- This is a biosimilar for a CD22-directed monoclonal antibody.
- Common adverse events include infusion-related reactions, edema, nausea, fatigue, headache, pyrexia, and constipation.
- Recommended dosing is 0.04 mg/kg administered as a 30-minute IV infusion on days 1, 3, and 5 of each 28-day cycle for a maximum of six cycles.
Duvelisib for relapsed/refractory chronic lymphocytic leukemia or small lymphocytic lymphoma
- Patients should have completed at least two prior therapies.
- Serious or fatal adverse events include infection, diarrhea or colitis, and pneumonia. Other adverse events include rash, fatigue, pyrexia, and cough.
- Recommended dosing is 25 mg orally twice a day.
Nivolumab for patients with metastatic small cell lung cancer
- Approval was extended to patients with metastatic small cell lung cancer, regardless of PD-L1 status.
- Patients need to have had at least one other line of platinum-based chemotherapy.
- Common adverse events are those of nivolumab for other approved indications: fatigue, decreased appetite, musculoskeletal pain, dyspnea, nausea, diarrhea, and cough.
