Management considerations for immune-mediated adrenal insufficiency1

GRADES BASED ON
CTCAE V5.02
GRADE 1 GRADE 2
GRADE 3 GRADE 4
Dose modification
with Opdualag
Continue treatment
Consider withholding depending on clinical severity until symptom improvement with hormone replacement. Resume treatment once acute symptoms have resolved. Withhold treatment until clinically stable or permanently discontinue depending on severity.
Management - Initiate symptomatic treatment, including hormone replacement as clinically indicated.
Administer 1 to 2 mg/kg/day prednisone or equivalent until improvement to Grade 1 or less if clinically appropriate. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month.
Follow-up -

Consider administration of other systemic immunosuppressants, including corticosteroid therapy, if clinically appropriate.
Treatments received by some patients in the clinical trial:

 

  • For Opdualag (mMel; n=355): of the patients with adrenal insufficiency (n=15), 87% received HRT, and 87% required systemic corticosteroids

 

NCI CTCAE V5.0 GRADING OF IMMUNE-MEDIATED ADRENAL INSUFFICIENCY2

Management Monitor patients for hyperglycemia or other signs and symptoms of diabetes. Initiate treatment with insulin as clinically indicated.
- Administer 1 to 2 mg/kg/day prednisone or equivalent until improvement to Grade 1 or less if clinically appropriate. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month.
