Immune-Related Adverse Events of Cancer Immunotherapies

Immune checkpoint inhibitors (ICIs)—which are monoclonal antibodies against
CTLA-4, PD-1, or PD-L1—have transformed treatment of many cancer types.
However, these treatments are associated with immune-related adverse events (irAEs).
Pre-existing autoimmune disease
is a strong risk factor for irAEs
Mechanism of irAEs
• CTLA-4 inhibitors: an imbalance in the ratio of regulatory T cells to type 17 T helper cells,
autoantibody production, and complement-mediated cellular damage
• PD-1/PD-L1 inhibitors: less well understood but could be due to reduced regulatory T cell numbers
Diagnostic
workup of
individuals
with suspected
irAEs depends

Cutaneous toxicities
are the earliest toxicity
associated with PD-(L)1
monotherapy and
combinations 
Nephritis
Common toxicity
associated
with chemo +
IO regimens
Patterns and Duration of Various irAEs
While onset of irAEs is generally 2 to 16 weeks after ICI initiation, some reports
have noted onset within a few days of starting therapy and >1 year after completion.
An irAE that occurs >3 months after ICI discontinuation is a delayed/late-onset irAE.
Some irAEs are recurrent (ie, occurring in the same organ or >1 time after
discontinuation), while others are chronic and can be active (ie, requiring
immunosuppression) or inactive (ie, not requiring immunosuppression).

Diagnosis and Management of Pulmonary irAEs
 Hold immunotherapy and reassess in 1-2 weeks
 Pulse oximetry rest and ambulation
 Consider chest imaging with CT (with contrast preferred)
 Repeat in 3-4 weeks
Moderate (grade 2): 25%-50%
lung involved
Severe (grade 3-4)
Grade 3: all lobes of lung or
>50% of lung parenchyma;
limited ADLs, oxygen requirement
Grade 4: life-threatening
 Hold immunotherapy
 Infectious workup (nasal swab, sputum, blood)
 Consider bronchoscopy and BAL
 Chest imaging with CT contrast
 Repeat in 3-4 weeks
 Consider empiric antibiotics
 Refractory: methylprednisolone 1-2 mg/m
2
/day; if no response in 3-4 days, treat as grade 3
 Permanently discontinue immunotherapy and move to inpatient care
 Infectious workup (nasal swab, sputum, blood)
 Pulmonary and infectious disease consultation
 Bronchoscopy with BAL
 Empiric antibiotics
 Methylprednisolone 1-2 mg/m
2
/day; when grade 1, taper over 6 weeks
 Refractory: infliximab, mycophenolate, or IVIG
 Pneumonitis: focal or diffuse inflammation of the lung parenchyma (typically identified on CT imaging)
 Diagnostic workup: CXR, CT, pulse oximetry; for grade ≥2, may include infectious workup
Mild (grade 1): <25% lung
involved
Additional considerations
• GI and pneumocystis prophylaxis may be offered to patients on prolonged steroid use (>12 weeks)
• Consider calcium and vitamin D supplementation with prolonged steroid use
• Bronchoscopy and biopsy; if clinical picture is consistent with pneumonitis, no need for biopsy
Supportive care: smoking cessation and vaccinations (influenza, pneumococcal)

• Patients and providers joined forces to make a discussion tool that helps
patients understand how their biomarker test results influence choosing the right
treatment for their solid-tumor cancer
• This discussion guide can support people with solid-tumor cancer to ask
their doctor or nurse the right questions about biomarker testing, ensure they
received the optimal level of biomarker testing, and understand how biomarker
testing can expand their optimal treatment options, including clinical trials
• The guide can also be used by healthcare providers to teach their patients
about how biomarker test results are used to make decisions about optimal
treatment and clinical trial options
LUNGevity offers a simplified guide to biomarker testing discussions for
patients and their healthcare team. It is available for download and can
be personalized with your institution’s logo and contact details.
The next page includes a tool designed for people with solid-tumor
cancer to use in communication about biomarker results
with their healthcare providers

Understanding Your Lung Cancer
Can Lead to Better Treatment Options
1. Has the cancer been tested for all biomarkers?
2. When is a tissue biomarker test necessary?
3. When is a blood biomarker test (ie, liquid biopsy) necessary?
4. How can I get a copy of my biomarker testing report?
5. Who will explain my biomarker testing results to me?
6. Is cancer biomarker testing the same as genetic testing for inherited cancer?
Are my family/children at risk?
7. Will I ever have to have more biomarker testing?
This tool is designed for people with solid-tumor cancer to use in communication
about biomarker results with their healthcare providers.

Biomarkers are changes in the cancer cells that may help guide treatment. Most biomarkers used to guide treatment plans are not passed on to children/family.
