About
This is a randomized, double-blind, single-dose, parallel comparison biosimilarity study conducted in healthy Chinese adult male subjects.
It is planned to enroll 198 male subjects in this study. Eligible subjects will be randomized into 2 dosing groups at 1:1 (GLR1044 group or Dupilumab group), i.e., 99 subjects in each group. Each subject is administered once by subcutaneous injection in the abdomen, during which the subject is required to be hospitalized for 4 days. The safety follow-up will last until D57.

5. The results of medical history review, physical examinations, laboratory tests, imaging examinations and ECG at screening/visit 2 (V2) are judged by the investigator to be normal or abnormal but not clinically significant.
No personal history of tuberculosis, no possible previous history of tuberculosis exposure, and no previous and/or current immunomodulatory treatment.
6.No personal history of tuberculosis, no possible previous history of tuberculosis exposure, and no previous and/or current immunomodulatory treatment.

2. Subjects who smoked > 5 cigarettes/day within 3 months prior to screening or who cannot stop using any tobacco products during the study.
3. The subject and/or first-degree relatives have a history of venous thromboembolic events or idiopathic venous thromboembolic events before screening.

7. The estimated glomerular filtration rate at screening is < 90 mL/min/1.73m2 as calculated using the CKD-EPI equation.
8. Any malignant tumor suspected or diagnosed prior to screening. 9. Subjects with blood donation or blood loss ≥ 400 mL within 3 months prior to screening, or subjects with bone marrow donation.
10. Subjects who have undergone major surgery (including but not limited to surgery requiring general anesthesia) or organ transplantation within 3 months prior to screening, or are still in a state of illness, trauma or incomplete recovery from surgery at the time of screening (e.g., significant impairment in daily living or working capacity compared to pre-illness/injury/surgery status), or plan to undergo surgery during the study or within two months after the end of the study.
