Signs and symptoms of colitis may include1
- Diarrhea (loose stools) or more frequent bowel movements than usual
- Stools that are black, tarry, sticky, or have blood or mucus
- Severe stomach area (abdominal) pain or tenderness
Management considerations for potential immune-mediated colitis1
GRADES BASED ON CTCAE V5.02 |
GRADE 1 | GRADE 2 | GRADE 3 | GRADE 4 |
---|---|---|---|---|
Dose modification with Opdualag | Continue treatment | Withhold treatment* | Withhold treatment* | Permanently discontinue treatment |
Management | - | Administer 1 to 2 mg/kg/day prednisone or equivalent until improvement to Grade 1 or less. 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 in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. |
NCI CTCAE V5.0 GRADING OF IMMUNE-MEDIATED COLITIS2
- GRADE 1: Asymptomatic; clinical or diagnostic observations only; intervention not indicated
- GRADE 2: Abdominal pain; mucus or blood in stool
- GRADE 3: Severe abdominal pain; peritoneal signs
- GRADE 4: Life-threatening consequences; urgent intervention indicated
In a trial that evaluated Opdualag, toxicity was graded per NCI CTCAE V5.0.1
*Resume in patients with complete or partial resolution (Grade 0 to 1) after corticosteroid taper. Permanently discontinue if no complete or partial resolution within 12 weeks of last dose or inability to reduce prednisone to 10 mg per day (or equivalent) or less within 12 weeks of initiating steroids.1
