Study Arms (1)

Experiment

EXPERIMENTAL

Patients who are enrolled in the study will be admitted to the study site on the day before each scheduled dose (D-1, D28, and D56) to complete the necessary pre-dose safety assessments and receive XKH001 subcutaneous (SC) injections on D1, D29, and D57.

Drug: XKH001 Injection

Interventions

Dosage: 600 mg Q4W (D1, D29 and D57) Method of administration: the drug will be administered by SC injection in an area 3 cm away from and within 5 cm around the umbilicus of the abdomen. Sites with skin damage, inflammation, ulceration, rash and scar should be avoided. Subjects should be closely observed for reactions within 4 h after dosing.

  • Male or female subjects aged 18 to 65 years (inclusive), with a body mass index (BMI) between 18 and 30 kg/m2 (inclusive);
  • Subjects diagnosed with asthma according to the Guidelines for the Prevention and Treatment of Bronchial Asthma (China) 2020 with an asthma course (since the first incidence) of at least 6 months and meet the following requirements at the same time:
  • Subjects with a positive reaction to at least 1 type of aeroallergen (such as dust mites, pollen, mold, or animal hair) in the skin prick test or allergen-specific IgE testing record before screening or during screening; Subjects with the upper limit of normal (ULN) at the site ≤ total serum IgE ≤ 1000 IU/mL at screening; Subjects with the bronchial provocation test FEV1 PD20 Mch ≤ 1.075 mg; Subjects with FEV1 ≥ 70% of the predicted value at screening;
  • Subjects with occasional asthma symptoms (≤ 2 times/week), treated only with ICS-LABA inhalation (Symbicort®, budesonide and formoterol fumarate powder for inhalation, 1 inhalation per dose) as needed. The subject does not need to use other asthma medications on a daily basis, and other asthma medications have been discontinued before screening:
  • Inhaled and nasal corticosteroids should be discontinued for 4 weeks; Leukotriene receptor antagonists should be discontinued for 2 weeks; Long-acting β-receptor agonists should be discontinued for 2 weeks; Anticholinergic drugs should be discontinued for 2 weeks; Antihistamines should be discontinued for 2 weeks; Theophylline drugs should be discontinued for 1 week.
  • Subjects with normal laboratory test and 12-lead ECG results or with abnormalities determined by the investigator not to be clinically significant at screening;
  • Women of childbearing potential must have a negative pregnancy test result and not be in the lactation period at screening; regardless of sex, all participants must agree to have no plans for reproduction during the study and within 6 months after the study, voluntarily adopt effective contraception measures, and have no plans for sperm/egg donation.

You may not qualify if:

  • Subjects who meet any of the following criteria must be excluded from this study:
  • Subjects who are current smokers or with a smoking history of \> 10 pack-years. Subjects who have quit smoking need to have quit smoking for at least 12 months before enrollment;
  • Subjects with hospitalization or emergency visits due to respiratory system and/or asthma-related conditions within 6 months before screening;
  • Subjects with worsening or exacerbation of asthma, or the use of systemic glucocorticoid therapy within 6 weeks before or during screening;
  • Subjects with a history of alcoholism or drug abuse;
  • Subjects who are allergic to the investigational product or any component of the formulation of the investigational product or have a history of allergy to protein drugs;
  • Subjects with elevated total IgE due to reasons other than allergens (e.g. parasitic infections and hematological disorders);
  • Subjects who have undergone allergen-specific immunotherapy or used immunosuppressants within 3 months before screening;
  • Subjects who have used biologics (such as monoclonal antibodies), including investigational biologics, within 6 months before screening;
  • Subjects who have received any anti-IgE antibody treatment or bronchial thermoplasty within 12 months before screening;
  • Subjects who have received live (attenuated) viral/bacterial vaccines or intravenous (IV) immunoglobulins (IgG) within 4 weeks before screening;
  • Subjects with respiratory system infection or have received a major surgery within 8 weeks before screening;
  • Subjects with a combination of other lung diseases such as COPD, bronchiectasis, or lung fibrosis;
  • Subjects with a history of contraindications to choline, such as myocardial infarction or stroke within the past 3 months, known heart disease, uncontrolled hypertension, aortic or brain aneurysm;
  • Subjects with neoplasm malignant within 5 years before screening or current neoplasm malignant;
  • +4 more criteria

Model Details: The screening period will not be more than 28 days (i.e., 4 weeks). The treatment period will be 12 weeks, and the follow-up period will be 12 weeks. All recruited patients with allergic asthma will undergo various screening procedures within 28 days prior to the first dose, and those who pass the screening will be sequentially enrolled. Patients who are enrolled in the study will be admitted to the study site on the day before each scheduled dose (D-1, D28, and D56) to complete the necessary pre-dose safety assessments and receive XKH001 subcutaneous (SC) injections on D1, D29, and D57. The patient will undergo regular safety assessment procedures (AE/SAE, vital signs, physical examination, laboratory tests, 12-lead electrocardiogram (ECG), etc.), FeNO, pulmonary function tests (FEV1 PD20 Mch), sputum induction, and other blood sample collections (PK, PD, and ADA) during the treatment period (D1-D85) and the subsequent 12-week follow-up period (\~D169).
