简要总结
The investigational drug, ZB001 is a humanized IgG1κ monoclonal antibody targeting human IGF-1R. The study is designed to evaluate the efficacy, safety, tolerability, and pharmacokinetics（PK）/pharmacodynamics (PD) profile of ZB001 in Chinese patients with Thyroid Eye Disease.

入选标准
- •Male or female adults, 18 years of age or older
- •Clinical diagnosis of Graves' ophthalmopathy and CAS evaluation of eyes under study ≥ 4 points (7 points in total)
- •Moderate-to-severe active thyroid-associated ophthalmopathy (i.e., severely affects daily life): exophthalmos extent is ≥18.6 mm, or progressive exophthalmos (≥3 mm greater than the previous exophthalmos record per the investigator); accompanied by at least one of the following symptoms: eyelid retraction ≥ 2 mm; moderate or severe soft tissue involvement (conjunctival congestion, edema, periorbital congestion or edema); non-persistent or persistent diplopia
- •Before Screening, evidence of eye symptoms or signs related to thyroid-associated ophthalmopathy in medical records for ≤1 year
- •Thyroid function normal, or only mild hyperthyroidism or hypothyroidism, defined as free thyroxine (FT4) ）and free triiodothyronine (FT3) levels within 0.5-1.5 times the normal range at Screening. Efforts have been made to correct any mild hypothyroidism or hyperthyroidism in a timely manner and try to maintain normal thyroid function throughout the study. Thyroidectomy is not an exclusion.
- •If the patient is a female of childbearing potential (including a female with menopause < 1 year, amenorrhea < 1 year, or without surgical sterilization), the pregnancy test result will be negative at Screening. Such patients must agree to use the effective birth control methods described in the relevant protocol section (Section 9.2 Contraception and Pregnancy) at least one complete menstrual cycle before the first dose of the study drug, and continue to use contraception methods for 100 days after the last dose
- •Male patients must be surgically sterilized for at least 6 weeks or agree to use the effective birth control methods described in the relevant protocol section (Section 9.2 Contraception and Pregnancy) before the first dose of the study drug and within 100 days after the last dose
排除标准
- •In the past 6 months, due to optic neuropathy, new visual field defect or color defect secondary to optic nerve involvement, the best corrected visual acuity of the study eye decreased, defined as the result of standardized visual acuity chart decreased ≥ 0.2
- •Corneal involvement of the study eye, and no improvement after medical interventions
- •CAS decreased ≥ 2 points from Screening Assessment to Day -1
- •The exophthalmos extent of the study eye ≥ 2 mm from Screening Assessment to Day -1
- •The study eye previously received orbital radiotherapy or surgery due to thyroid-associated ophthalmopathy
- •Known history of clinically significant ear disease, ear surgery or hearing loss
- •Inflammatory bowel disease (e.g., biopsy-proven or clinical evidence of inflammatory bowel disease)
- •Cumulative use of glucocorticoid equivalent to ≥ 1g methylprednisolone as thyroid-associated ophthalmopathy treatment (A lower cumulative dose [<1g] of glucocorticoid used before Screening, or hormone eye drops withdrawn for ≥ 6 weeks before Screening, is allowed for inclusion)
- •Received any doses of oral corticosteroids to treat diseases other than thyroid-associated ophthalmopathy within 4 weeks before Screening (local application is allowed for inclusion)
- •Pregnant or lactating females
- •Smokers (≥ 5 cigarettes/day) or former smokers (≥ 5 cigarettes/day) quit within 6 months before enrollment in the study
- •Any vaccination planned during the study

结局指标
主要结局
Number of participants with Adverse Events, Serious Adverse Events, and Laboratory Evaluations as assessed by CTCAE v5.0
时间窗: through study completion, up to 169 days
The exophthalmos response rates of study eye at Week 6 and Week 12 (defined as the proportion of patients whose exophthalmos measured by Hertel exophthalmos meter decreased ≥ 2mm from baseline)
时间窗: At week6 and week 12
次要结局
- Change from baseline in the study eye at Week 6, Week 12 and Week 24 of Intraocular pressure(At week6, week 12 and week 24)
- Change from baseline in the study eye at Week 6, Week 12 and Week 24 of Exophthalmos measured by MRI/CT scan(At week6, week 12 and week 24)
- Change from baseline in the study eye at Week 6, Week 12 and Week 24 of Facial fat volume measured by MRI/CT scan(At week6, week 12 and week 24)
- Change from baseline in the study eye at Week 6, Week 12 and Week 24 of Graves ophthalmopathy - Visual function QOL. The range of score is from 0-100. The higher change of quality of life means the better outcome.(At week6, week 12 and week 24)
- Serum IGF-1 concentrations in the blood over time(Before and after drug administration, performed according to the protocol visit time specified in the plan, up to 169 days)
- Maximum observed concentration (Cmax)(Before and after drug administration, performed according to the protocol visit time specified in the plan, up to 169 days)
- Time to measured peak concentration (Tmax)(Before and after drug administration, performed according to the protocol visit time specified in the plan, up to 169 days)
