- Registration Number
- NCT05018299
- Lead Sponsor
- Oneness Biotech Co., Ltd.
- Brief Summary
This is a randomized, placebo controlled and double blind study to evaluate the safety, tolerability, pharmacokinetics, and clinical activity of FB704A in adult patients with severe asthma. The study comprised a 4-week screening period, a 8-week treatment period and a 12-week follow-up period.
- Detailed Description
Approximately 40 subjects who meet the criteria for study entry are planned to be enrolled to the study. Eligible subjects will be randomized to receive placebo or FB704A in a 1:1 ratio. There are 20 subjects participate in each arm.
Eligibility will be checked in patients with severe asthma during the 4-week screening period. Potential candidates should provide signed informed consent forms before starting the screening activities. The subjects will receive four dose of 4 mg/kg FB704A or placebo. The study drug will be administered as a 1-hour IV infusion.
Patients may administer Short-acting beta agonists (SABAs), such as albuterol as rescue medications as needed throughout the study.
Subjects will have site visits after receiving study drug for efficacy, safety, PK, and biomarker evaluation (see Study Flow Chart). Subjects who prematurely withdraw from the study will have an end of study (EOS) visit within 7 days.
Relative change in pre-bronchodilator FEV 1 , post-bronchodilator FEV 1, exhaled NO and asthma symptom s will be evaluated during the study.

- 40
1.18 to ≦75 years of age, either sex, any race.
2.Diagnosed as severe asthma based on 2020 GINA guideline.
3.An ACT score is <20.
4.Induced sputum neutrophil count ≧50% of total sputum cells during Screening.
5.Documented diagnosis of severe asthma (within past 5 years), and have at least one of the following:≧12% and/or 200 mL improvement in Forced Expiratory Volume in 1 second (FEV1) post-bronchodilator, and/or airway hyperresponsiveness (eg, positive methacholine challenge <8 mg/mL).
6.Nonsmoker or previous smoker with cumulative smoking history less than 10 pack-years (pack-year = 20 cigarettes smoked daily for 1 year). Previous smokers may not have smoked within 1 year prior to Screening. A smoker is defined as a subject who has taken inhaled nicotine containing products (e.g. cigarette, cigar, pipe), including e-cigarettes prior to screening.
7.Must not have had a severe asthma exacerbation of asthma for 4 weeks prior to Screening and must be on a stable medication regimen for asthma at least 4 weeks prior to Screening.
A Severe asthma exacerbation is defined as a deterioration of asthma leading to treatment for 3 days or more with systemic glucocorticoids or hospitalization or an emergency department visit leading to treatment with systemic glucocorticoids.
8.Must be willing to give written informed consent to participate in the study.
9.Must be capable of complying with the dosing regimen, adhere to the visit schedule, and participate in all treatment procedures, including sputum induction.
10.Female subject of childbearing potential must have a negative serum pregnancy test at Screening and must be using a medically acceptable, highly effective, adequate form of birth control (ie, failure rate <1% per year when used consistently and correctly) prior to Screening and agree to continue using it while in the study (Screening and Treatment Periods). Medically acceptable, highly effective forms of birth control are hormonal implants, oral contraceptives, medically acceptable prescribed intrauterine devices (IUDs), and monogamous relationship with a male partner who has had a vasectomy. Female subject who is not of childbearing potential must have a medical record of being surgically sterile (eg, hysterectomy, tubal ligation), or be at least 1 year postmenopausal. Absence of menses for at least 1 year will indicate that a female is postmenopausal. A female subject should be encouraged to continue using a highly effective method of birth control for 30 days following the end of treatment.
Male subject must agree to use an adequate form of contraception for the duration of the study and agree to have sexual relations only with women who use a highly effective birth control method.
