Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or females 18-75 years old.
• Subjects diagnosed with moderate-to-severe allergic asthma [Global Initiative for Asthma [GINA]; GINA, 2021) at least 12 months prior to Visit 1.
• Documented reversibility from historical data of at least 12% and 200 mL in FEV1 after the administration of 200 to 400 mcg albuterol/salbutamol (or other standard office practice) OR documented airway hyperresponsiveness (methacholine PC20 < 8 mg/mL [or PC20 < 16 mg/mL on ICS]) OR airflow variability in clinic FEV1 >12% and 200 mL between visits outside of respiratory infections, documented in the past 24 months prior to Visit 1 if documented reversibility and airway hyperresponsiveness data are not available.
• Subjects must have a pre-bronchodilator FEV1 value of ≥ 40% and ≤ 80% predicted within 2 months from randomization.
• Subjects must have received a physician-prescribed asthma regimen with medium- or high-dose ICS plus LABA for at least 3 month prior to Visit 1 and the dose of ICS must be stable for at least 30 days prior to Visit 1 and throughout the screening period.
• High-dose ICS is defined as total daily dose of >500 mcg fluticasone propionate or equivalent
• Medium-dose ICS is defined as a total daily dose of 250 to 500 mcg fluticasone propionate or equivalent.
• Equivalence ICS doses will be based upon the GINA guidelines (GINA, 2021)
• According to the medical history, subject have no more than a maximum of 2000 mcg/day equipotent ICS daily dosage of fluticasone propionate or equivalent in 3 months before visit 1.
• Prior to screening, subjects must be on a stable dose of any of the following doses and formulations of ICS/LABA combination therapy for at least 1 month:
• Fluticasone/salmeterol combination therapy
• Advair® Diskus - dry powder inhaler (DPI): 250/50 μg BID or 500/50 μg BID, or
• Advair® HFA - metered dose inhaler (MDI): 230/42 μg BID or 460/42 μg BID, or
• Budesonide/formoterol combination therapy (Symbicort® -160/4.5 μg BID or 320/9 μg BID), or
• Mometasone/formoterol combination therapy (Dulera® -200/10 μg BID or 400/10 μg BID).
• Other equivalents medium to-high dose medication following the GINA guidelines (GINA, 2021)
• Subjects must have a documented history of protocol-defined asthma exacerbation at least 1 or more times within the 12 months.
• A total serum IgE ≥ 125 IU/mL during screening prior to randomization.
• Subjects must have at least one positive in skin prick test or at least one environmental allergen-specific IgE greater than normal range.
• Uncontrolled asthma demonstrated both during the screening period and at the time of randomization defined as ACQ-5 (5-item Asthma Control Questionnaire) ≥ 1.5
• If recently treated for respiratory tract infection, the treatment must have been completed at least 4 weeks prior to screening. Subjects who have an upper respiratory tract infection during screening are allowed to be rescreened 4 weeks after resolution.
• Female subjects of childbearing potential must use at least two forms of birth control. One must be barrier protection (i.e., condom or female condom) and the other is one of acceptable method of birth control (ie, diaphragm, intrauterine device, hormonal contraceptives, or abstinence) throughout the study. Subjects who are surgically sterile (ie, hysterectomy, bilateral tubal ligation, or bilateral oophorectomy), or postmenopausal (defined as amenorrhea for 12 consecutive months and documented serum follicle stimulating hormone level >40 mU/mL) will be considered as no childbearing potential. All female subjects of child-bearing potential must have a negative serum pregnancy test at screening.
• Note: The subject must use the methods of contraception mentioned above during study period and at least 120 days after the last dosing of FB825.
• The subject has a body weight ≥ 40 kg at screening.
• The subject has a normal or non clinically significant abnormal, as determined by the investigator, 12-lead electrocardiogram (ECG).

You may not qualify if…

• Asthma exacerbation or any other reason requiring systemic steroids in the 30 days prior to randomization. Subjects are allowed to be rescreened 30 days after completion of treatment.
• >20% relative change in post-bronchodilator FEV1 between screening and randomization.
• Female subjects who are pregnant or lactating.
• A positive human immunodeficiency virus (HIV) test (e.g., HIV Ag/Ab combo test) at screening or subject taking antiretroviral medications, as determined by medical history.
• Patients with positive HBeAg or HCV RNA results should be excluded as they are indications of active Hepatitis B virus and Hepatitis C virus replication.
• Active lung diseases (e.g., bronchitis, chronic obstructive pulmonary disease) other than allergic asthma.
• Use of any experimental drug within 30 days or 5 half-lives, whichever is longer, prior to or during the screening period.
• Current or history of treatment with a monoclonal antibody, for example, IL-4, IL-5, IL-13 or IL-15 antibody treatment within 6 months prior to the screening.
• Current or history of treatment with anti-IgE antibody treatment within 6 months or 5 half-lives, whichever is longer.
• The subject has a history of alcohol or drug abuse that would impair or risk the patients' full participation in the study, in the opinion of the investigator.
• The subject has any condition that, in the opinion of the investigator, would compromise the study or the well-being of the subject or prevent the subject from meeting or performing study requirements.
• The subject has indication of severe liver disease, defined by serum levels of either alanine aminotransferase (ALT), aspartate transaminase (AST) above 3x upper limits of normal (ULN) or elevated total bilirubin >2x ULN as determined at screening.
• The subject has severe kidney disease, defined as estimated GFR <30ml/min/1.73m2 or creatinine > 3x ULN.
• The subject has known or suspected history of immunosuppression or immunodeficiency.
• Known history of active tuberculosis (TB) or evidence of tuberculosis infection as defined by a positive purified protein derivative (PPD) skin test and/or interferon-gamma release assay. The interferon-gamma release assay should be repeated in case of an indeterminate result.
• The subject has history of malignancy within 5 years before the screening period. Patients with non-invasive carcinoma in-situ of the cervix, basal cell carcinoma or squamous cell carcinoma of the skin may be eligible if they have undergone curative resection at least 12 months prior to screening.
• Current smoker with > 10 packs 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.
• High risk of parasite infection
• Risk factors for parasitic disease (living in an endemic area, travel within the last 6 months to regions where geohelminthic infections are endemic, and/or chronic immunosuppression).
• AND
• Evidence of parasitic colonization or infection on stool evaluation for ova and parasites.
• Note: stool ova and parasite evaluation will only be conducted in patients with risk factors and an eosinophil count more than twice the upper limit of normal.
• The subject has received live vaccine within 12 weeks or COVID-19 vaccination within 2 weeks prior to dosing or planned live attenuated vaccinations during the study.
• The subject has a history of any clinically relevant arrhythmias as determined by the investigator.
• The subject has a history of respiratory failure or near fatal asthma events which resulted in intensive care unit admission or intubation within five years before the screening period.
