anti-vegf therapy for acute thyroid eye disease

Conditions: Thyroid Eye Disease

Summary: the primary objective of this clinical trial is to assess the safety and tolerability of sub-tenon aflibercept in combination with either saline or hyaluronidase (ha) in patients with acute thyroid eye disease (ted) as assessed by the incidence and severity of adverse events from baseline to day 45. participants will undergo clinical examinations and receive three injections of aflibercept with saline, aflibercept with hyaluronidase, or hyaluronidase.


Eligibility criteria:
inclusion criteria: 1. minimum of 18 years-old 2. active thyroid eye disease 3. clinical activity score (cas) between 3 and 5, inclusive 4. phakic and pseudophakic eyes are allowed in the study. 5. willing and able to provide written informed consent after the nature of the study has been explained, and prior to any research-related procedures 6. willing and able to comply with clinic visits and study-related procedures 7. only one eye will be enrolled. the worse eye (demonstrating any of these features: worse hvf results, worse restricted motility, worse visual acuity, worse edema, worse proptosis, worse eyelid retraction) will be enrolled. if both eyes are equivalent, we will enroll the non-dominant eye. exclusion criteria: 1. history of orbital, strabismus, or eyelid surgery or orbital radiation 2. optic neuropathy or other vision-threatening signs 3. patients currently on systemic or topical steroids. if they received steroids in the past, they would require a 6 week washout period and the cumulative dose of steroids must be less than 1 gram of methylprednisolone (or equivalent). during the washout period we will contact patients by phone weekly to monitor their safety and address any concerns they may have related to no longer taking steroids . 4. patients who have taken teprotumumab (tepezza.) 5. patients who have received intraocular anti-vegf medications within 1 year of screening 6. patients who have a history of receiving systemic anti-vegf 7. presence of other retinal vascular diseases (diabetic retinopathy, vein occlusion) that could affect the vegf levels within the eye 8. history of stroke or prior myocardial infarction 9. known hypersensitivity to aflibercept 10. infectious conjunctivitis, keratitis, or endophthalmitis of either eye 11. presence of a glaucoma shunting or filtration device that is subconjunctival 12. previous participation in any studies of investigational drugs within 1 month preceding day 0 13. any clinically significant acute or chronic medical condition that would preclude participation in a clinical study 14. pregnant or breast-feeding women 15. sexually active men\* or women of childbearing potential\*\* who are unwilling to practice adequate contraception during the study (adequate contraceptive measures include stable use of oral contraceptives or other prescription pharmaceutical contraceptives for 2 or more menstrual cycles prior to screening; intrauterine device \[iud\]; bilateral tubal ligation; vasectomy; condom plus contraceptive sponge, foam, or jelly, or diaphragm plus contraceptive sponge, foam, or jelly) 16. history of hyaluronidase (ha) injection after the diagnosis of thyroid eye disease 17. taking part in other research studies in the past 12 months that have involved radiation exposure 18. participated in other research studies in the past 12 months that required radiologic imaging (particularly ct scans and not mris)
