Background
- Monoclonal antibody to programmed cell death 1 (PD-1)
- Increases anti-tumour T-cell response by blocking interaction between PD-1 on T-cells and PD-L1 on cancer cells
- Indications include melanoma and non-small cell lung cancer
Safety
Adverse Effects
- Immune-related adverse events are common
Immune-Mediated Pneumonitis
- Pneumonitis in a life-threatening side effect occuring in 1-5% of treated patients1
- Slightly more frequent in patients with known asthma or COPD, or who have received chest radiation
- Median time to onset is 2.8 months
- Most cases are mild to moderate, though there has been at least one death
- Pattern on radiography is of ILD (mostly organizing pneumonia, but occasionally NSIP), hypersensitivity pneumonitis, or ground-glass opacities2
- May be managed with prednisone
Infections
- Not particularly immunosuppressive
- Severe infections include mainly bacterial infections (pneumonia, genitourinary infection, SSTI, and bacteremia)
- Possibly occasional viral infections (enterovirus and rhinovirus), rare fungal infections
