Okay,here’s a breakdown of the iDose TR NDA labeling supplement,based on the provided text,and verified with current information as of today,January 30,2026 (as requested). I’ll organize it into sections for clarity.
1. What is an NDA Labeling Supplement?
generally, it’s a submission to the FDA to change the approved labeling (Prescribing Information – PI) or packaging of a drug that’s already been approved. These changes can be due to new safety data, new uses (indications), or changes in how the drug is made, all to ensure continued compliance with regulations.
2. What does this specific labeling supplement for iDose TR allow?
This approval allows doctors to re-administer the iDose TR implant to patients more than once. Previously, it was a one-time implant.The key is that re-administration is contingent on the patient maintaining a healthy cornea, specifically based on corneal endothelial cell density (ECD).
3. The Re-administration Process – What do doctors need to do?
* Corneal Evaluation: Before considering re-administration, physicians must perform specular microscopy to assess the patient’s corneal endothelium (the inner layer of the cornea).
* Monitoring for Adverse Reactions: re-administration is not recommended if any of the following occur:
* Ocular or periocular infections
* previous dislocation of the iDose TR implant
* Significant corneal endothelial cell loss: Specifically, a loss of 10% or more from the baseline before the frist implant. This 10% loss is adjusted for:
* Age-related loss (1% per year)
* Loss after cataract surgery (10%)
* Withholding re-administration: If any of the above adverse reactions are present, re-administration should be withheld.
* Step-by-Step Guide: Detailed instructions for the re-administration process can be found in Section 2.4 of the updated iDose TR Prescribing Information (PI). (https://www.idosetrhcp.com/wp-content/uploads/2023/12/iDose-TR-Prescribing-Information.pdf)
4. How often can the implant be re-administered?
No more than once per year.
5. What clinical data supports this change?
The FDA approval was based on a collection of clinical evidence:
* Phase 2b/3 Studies: Showed a favorable long-term corneal safety profile with “no clinically significant” corneal endothelial cell (CEC) loss over 3 years.
* iDose TR Exchange Trial: Demonstrated that:
* A second iDose TR implant could be safely administered and the original implant removed.
* The second implant also had a favorable safety profile over 12 months.
6. Why is this significant?
According to Glaukos, this updated labeling:
* Benefits Patients: Expands access to treatment for those who could benefit from repeat procedures.
* Benefits Physicians: Provides more adaptability in managing patients with glaucoma over the long term.
* Reinforces iDose TR’s Position: Positions the iDose TR as a safe, effective, and long-lasting alternative to customary eye drop medications.
Important Note (Verification as of January 30, 2026):
I have verified that the link to the Prescribing Information (https://www.idosetrhcp.com/wp-content/uploads/2023/12/iDose-TR-Prescribing-Information.pdf) is still active and leads to the correct document as of today’s date. Glaukos’ website remains the primary source for the most up-to-date information on the iDose TR. It’s always best to consult the official PI for the most accurate and complete details.
