Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a clinical trial assessing the safety, tolerability and pharmacokinetics (PK) of an investigational drug, VRDN-003, in participants with TED (Thyroid Eye Disease)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized (meaning participants will be assigned to study arms by chance), open-label (meaning study doctor, participant and the sponsor will know which study arm participant is assigned to), parallel-group study that will enroll participants with TED of any duration. The key objectives of this study are to determine if VRDN-003 is safe and tolerable and to see how the body reacts to VRDN-003 when administered as a series of subcutaneous (SC) injections every 4 weeks or every 8 weeks in participants with TED either via autoinjector or via vial and syringe.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Not require immediate ophthalmological or orbital surgery in the study eye for any reason
* Must agree to use highly effective contraception as specified in the protocol
* Female TED participants must have a negative serum pregnancy test at screening

Exclusion Criteria

* Must not have received prior treatment with another anti-IGF-1R therapy
* Must not have received systemic corticosteroids for any condition, including TED, or selenium within 2 weeks prior to first dose.
* Must not have received other immunosuppressive drugs for any condition, including TED, or any other therapy for TED, within 12 weeks prior to first dose
* Must not have received an investigational agent/device for any condition, including TED, within 8 weeks or longer (depending on the type of agent/device) prior to first dose
* Must not have received radioactive iodine (RAI) treatment within 8 weeks prior to first dose
* Must not have had previous orbital irradiation or decompression surgery for TED to the study eye's orbit
* Must not have a pre-existing ophthalmic condition in the study eye which in the study doctor's opinion, would interfere with interpretation of study results
* Must not have abnormal hearing test before first dose or history of ear conditions considered significant by study doctor
