入选标准

  • Subjects voluntarily participating in the study and signing the informed consent form;
  • Aged 18-75 years (inclusive), of any gender;
  • Clinical diagnosis of chronic Thyroid Eye Disease (TED) , with symptoms in the study eye more than 12 months and less than 10 years.
  • Subjects with a clinical diagnosis of moderate to severe TED at screening and baseline.
  • Does not require immediate surgical ophthalmological intervention, and no corrective surgery/orbital radiotherapy is planned during the study.
  • Diabetic subjects must have well-controlled stable disease.
  • Sufficient bone marrow and organ function.
  • Eligible subjects of childbearing potential (male and female) must agree to use reliable contraceptive methods; female subjects of childbearing potential must have a negative blood pregnancy test within 7 days before the first use of the study drug and must not be breastfeeding.
  • Subject is willing and able to comply with the prescribed treatment protocol and evaluations for the duration of the study.

排除标准

  • Decreased best corrected visual acuity due to optic neuropathy as defined by a decrease in vision within the last 6 months of two lines of Snellen chart, new visual field defect or color defect secondary to optic nerve involvement.
  • Corneal decompensation unresponsive to medical management.
  • Decrease in CAS of ≥ 2 points or decrease in proptosis of ≥ 2 mm between screening and baseline.
  • Free thyroxine (FT4) and free triiodothyronine (FT3) levels <50% above or below the normal reference range at screening.
  • Subjects who have previously received orbital radiotherapy or ophthalmic surgery for TED.
  • Subjects who received oral or intravenous corticosteroids or corticosteroid eye drops/ointments for TED within 4 weeks before the first dose; subjects who received periorbital/orbital steroid injections within 3 months before the first dose.
  • Subjects who used oral or intravenous corticosteroids for reasons other than TED within 4 weeks prior to Screening, excluding local use (topical, nasal, inhalation).
  • Any previous treatment with rituximab, tocilizumab, other immunosuppressive agent use within 3 months prior to Screening.
  • Previous treatment targeting IGF-1R.
  • Selenium and biotin must be discontinued 3 weeks prior to Screening and must not be restarted during the trial; however, taking a multivitamin that includes selenium and/or biotin is allowed.
  • Use of an investigational agent for any condition within 30 days prior to Screening or anticipated use during the course of the trial.
  • Identified pre-existing ophthalmic disease that, in the judgment of the Investigator, would preclude study participation or complicate interpretation of study results.
  • Malignant condition in the past 5 years before signing the ICF (except successfully treated basal/squamous cell carcinoma of the skin).
  • Acute cardiovascular disease history or treatment within 6 months before the first dose.
  • Presence of poorly controlled hypertension with systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥ 100 mmHg; Renal artery stenosis.
  • Pregnant or lactating women.
  • Drug or alcohol abuse during the screening period.
  • Hearing impairment history in either ear during the screening period; or abnormal pure tone audiometry results.
  • Biopsy-proven or clinically suspected inflammatory bowel disease.
  • Positive results for serum virology tests (defined as pos
  • Subjects who received or planned to receive live or attenuated live vaccines within 4 weeks before the first dose or during the study period.
  • Subjects who underwent major surgery within 4 weeks before the first dose or are expected to undergo surgery during the study period or within 4 weeks after the study.
  • Known hypersensitivity to any of the components of MNB018A or prior hypersensitivity reactions to mAbs.
