Details and patient eligibility

About

Please note that Phase 1/2 (HV &amp ; TED MAD) cohorts and Phase 3 component (THRIVE) - recruitment is complete.

The investigational drug, veligrotug (VRDN-001), is a monoclonal antibody that inhibits the activity of a cell surface receptor called insulin-like growth factor-1 receptor (IGF-1R). Inhibition of IGF-1R may help to reduce the inflammation and associated tissue swelling that occurs in patients with thyroid eye disease (TED). This clinical trial will evaluate the safety, tolerability and pharmacokinetics (the concentration of drug in the blood over time) of veligrotug (VRDN-001) in healthy volunteers (HV) and in patients with TED. Study participants with TED will also be evaluated over time for changes in their signs and symptoms of TED compared to their baseline measurements.

Key Inclusion Criteria for Participants with TED in Phase 1/2 MAD cohorts:

  • Must have moderate to severe active TED with documented evidence of ocular symptoms or signs that began within 1 year prior to screening OR moderate to severe chronic TED with documented evidence of ocular symptoms or signs that began over 1 year prior to screening
  • Must have active TED and a Clinical Activity Score (CAS) of ≥ 4 on the 7-item scale for the study (more proptotic) eye OR chronic TED with no CAS requirement
  • Must agree to use highly effective contraception as specified in the protocol
  • Female TED participants must have a negative serum pregnancy test

Key Exclusion Criteria for Participants with TED in Phase 1/2 MAD cohorts:

  • Must not have corneal decompensation in the study eye unresponsive to medical management
  • Must not have had previous orbital irradiation or surgery for TED in the study eye
  • Must not have a history of inflammatory bowel disease Must not have clinically significant ear pathology or hearing impairment
  • Must not have received an investigational agent for any condition within 60 days
  • Female TED participants must not be pregnant or lactating

Key Inclusion Criteria for Participants with TED in Phase 3 study:

  • Must not have received rituximab, tocilizumab or other immunosuppressive agents within 8 weeks prior to Day 1
  • Must not have a pre-existing ophthalmic condition in the study eye that in the opinion of the Investigator would confound interpretation of the study results
  • Must not have had previous orbital irradiation or surgery for TED in the study eye
  • Must not have a history of inflammatory bowel disease
  • Must not have a history of or screening audiometry assessment of clinically significant (as determined by investigator) ear pathology, relevant ear surgery, or hearing loss
  • Must not have received an investigational agent for any condition
  • Female TED participants must not be pregnant or lactating
