Zeposia and Diabetes Mellitus: Required Precautions

Patients with diabetes mellitus require an ophthalmic evaluation before starting Zeposia (ozanimod) and regular follow-up eye examinations throughout treatment due to increased risk of macular edema. 1

Primary Risk: Macular Edema

Diabetes is a pre-existing risk factor that increases susceptibility to macular edema during ozanimod therapy. The clinical trial data demonstrate:

  • Low overall incidence (≤0.6% in UC trials, 0.4% in MS trials) with long-term treatment 1
  • Most macular edema cases occurred in patients with pre-existing risk factors or comorbid conditions, including diabetes 1
  • Three of four confirmed cases in MS patients had pre-existing risk factors 1

Mandatory Monitoring Protocol

Pre-Treatment Requirements

  • Obtain baseline ophthalmic evaluation before initiating Zeposia in all diabetic patients 1, 2
  • This evaluation should be performed by an eye care professional 2

During Treatment Monitoring

  • Perform regular follow-up ophthalmic evaluations throughout ozanimod treatment in diabetic patients 1
  • Monitor for any vision changes, including: 1
    • Distorted contour and color of objects
    • Unequal size with monocular view
    • Any other visual disturbances

Patient Education

  • Instruct diabetic patients to immediately contact their healthcare provider if they experience any changes in vision while taking Zeposia 2
  • Advise patients that their risk of macular edema is increased due to diabetes 2

Clinical Context and Safety Profile

The evidence from extensive clinical trial experience provides reassurance:

  • Over 2,196 patient-years of exposure in UC trials showed macular edema incidence ≤0.6% 1
  • Up to 5 years of treatment in MS trials demonstrated 0.4% incidence 1
  • No cases required treatment discontinuation when appropriately monitored 1

Critical Pitfall to Avoid

Do not initiate Zeposia in diabetic patients without baseline ophthalmologic assessment. This screening is essential to establish baseline retinal status and identify any pre-existing diabetic retinopathy that would require more intensive monitoring. 1, 2

The combination of pre-treatment screening and regular monitoring allows safe use of ozanimod in diabetic patients while maintaining vigilance for this rare but important complication. 1
