E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine the effect of reslizumab (110 mg) administered subcutaneously every 4 weeks on clinical asthma exacerbations (CAEs) in adults and adolescents with asthma and elevated blood eosinophils who are inadequately controlled on standard-of-care asthma therapy. |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy objectives are to evaluate the effects of reslizumab compared with placebo on a range of clinical markers of asthma control including pulmonary function (forced expiratory volume in 1 second [FEV1]). |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients may be included in the study only if they meet all of the
following criteria:
a. Written informed consent is obtained. A patient 12 through <18 years
of age must provide assent, and their parent(s) or legal guardian(s)
must provide consent.
b. The patient is male or female, 12 years of age and older, with a
diagnosis of asthma. (Patients 12 to <18 years of age are excluded from
participating in South Korea and Argentina, and patients 66 years of age
and older are excluded from participating in South Korea.)
c. The patient has had at least 2 documented asthma exacerbations
requiring the use of systemic (oral, intramuscular, or intravenous)
corticosteroids within 12 months of signing the Informed Assent
Form/Informed Consent Form.
d. The patient has an ACQ-6 score of at least 1.5 at screening (visit 1).
e. The patient has a blood eosinophil level of at least 300/µL during the
screening period (ie, before visit 2).(A maximum of 30% of the patients
with blood eosinophil levels of 300/μL to <400/μL will be enrolled.
When this 30% threshold has been reached, only patients with blood
eosinophil levels of ≥400/μL will then be enrolled).
f. The patient has an FEV1 reversibility of at least 12% after
administration of inhaled SABA according to standard American Thoracic
Society (ATS) or European Respiratory Society (ERS) protocol.
Documented historical reversibility within 12 months of signing the
Informed Assent Form/Informed Consent Form is acceptable.
g. The patient has required at least a medium total daily inhaled
corticosteroid (ICS) dose based on Global Initiative for Asthma 2016
clinical comparability table (Appendix A) for at least 3 months. For
ICS/LABA combination preparations, the mid-strength approved
maintenance dose in the local country will meet this ICS criterion.
h. The patient has required an additional asthma controller medication
(eg, long-acting beta-2-agonist[LABA], long-acting muscarinic
antagonist [LAMA], leukotriene receptor antagonist [LTRA], or
theophylline preparations), besides inhaled corticosteroids, for at least 3
months or a documented failure in the past 12 months of an additional
asthma controller medication for at least 3 successive months.
i. Females of childbearing potential (not surgically sterile by
hysterectomy, bilateral salpingectomy, bilateral oophorectomy, or 2
years postmenopausal) must have exclusively same-sex partners or use
medically acceptable methods of birth control and must agree to
continue use of this method for the duration of the study and for 5
months after the last study drug dose. Acceptable methods of birth
control include intrauterine device, systemic hormonal contraceptive
(oral, implanted, transdermal, or injected), barrier method with
spermicide, abstinence, bilateral fallopian tube occlusion, and partner
vasectomy. Contraception is further clarified in an administrative letter
in Section 1.1.1.
j. The patient must be willing and able to comply with study restrictions,
perform requisite procedures and remain at the clinic for the required
duration during the study period, and be willing to return to the clinic for
the follow-up evaluation as specified in this protocol.
k. The patient must maintain their usual asthma controller regimen
without change throughout the screening and run-in periods. A patient
who experiences an asthma exacerbation during this time that requires
additional medication, beyond increased SABA use, will be considered to
have failed screening/run-in and cannot undergo randomization. A
patient may be rescreened for this reason 1 time only. The duration
between the date of Screen Failure and the re-screening must be >30
days. Patients may be screened again if they did not meet
spirometry/reversibility criteria initially.
I. In order to be randomized, a patient must demonstrate the following:
-- inadequate asthma control at baseline/DoR as evidenced by:
○ daytime asthma symptom score >0 on >2 of the previous 7 days
based on the asthma control diary received at run-in OR
i) need for reliever SABA use on >2 of the previous 7 days OR
ii) ≥1 nighttime awakening due to asthma over the previous 7 days OR
○ pre-bronchodilator FEV1 <80% predicted at baseline/DoR
AND
-- completion of at least 4 days of diary entries or equivalent during the
last 7 days of run-in. A patient may be rescreened for this reason 1 time
only. |
|
E.4 | Principal exclusion criteria |
Patients will be excluded from participating in this study if they meet any of the following criteria:
a. The patient has any clinically significant, uncontrolled medical condition (treated or untreated) that would interfere with the study schedule or procedures, interpretation of efficacy results, or compromise the patient’s safety.
b. The patient has another confounding underlying lung disorder (eg, chronic obstructive pulmonary disease, interstitial lung disease, bronchiectasis, eosinophilic granulomatosis with polyangiitis [EGPA, also known as Churg-Strauss syndrome], or allergic bronchopulmonary aspergillosis [ABPA]).
c. The patient has a known hypereosinophilic syndrome.
d. The patient has a diagnosis of malignancy within 5 years of the screening visit, except for treated and cured non-melanoma skin cancers.
e. The patient is a pregnant or lactating woman, or intends to become pregnant during the study or within 5 months after the last dose of study drug. Any woman becoming pregnant during the study will be withdrawn from the study.
f. The patient required treatment for an asthma exacerbation within 4 weeks of screening or during the screening/run-in period.
g. The patient is a current smoker (ie, has smoked within the last 6 months before screening) or has a smoking history ≥10 pack years.
h. The patient is currently using any systemic immunosuppressive or immunomodulatory biologic (eg, anti-immunoglobulin E monoclonal antibody or other monoclonal antibody [eg, mepolizumab] or soluble receptors) or non-biologic (eg, methotrexate or cyclosporine), except maintenance oral corticosteroids for the treatment of asthma (up to and including 10 mg of prednisone daily or equivalent). Note: Previous use of such agents that occurred >5 half-lives from the initial screening visit may be allowed, if approved by the medical monitor.
i. The patient participated in a clinical trial within 30 days or 5 half-lives of the investigational drug before screening, whichever is longer.
j. The patient was previously exposed to benralizumab within 12 months of screening.
k. The patient was previously exposed to reslizumab.
l. The patient has a history of an immunodeficiency disorder including HIV.
m. The patient has current or suspected drug and alcohol abuse.
n. The patient has an active helminthic parasitic infection or was treated for one within 6 months of screening.
o. The patient has a history of allergic reaction or hypersensitivity to any component of the study drug.
p. The patient has a history of latex allergy. (The current prefilled syringe device has a natural rubber component to the needle shield.) |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is the frequency of CAEs per patient during the 52-week treatment period.
For this study, a CAE is defined as a clinically judged deterioration in asthma control as determined by the
investigator and as evidenced by new or worsening asthma signs or symptoms based on the patient history, asthma control diary, physical examination, and/or ambulatory or clinic visit assessment of lung function and that results in a medical intervention, including at least 1 of the following:
-- use of systemic corticosteroids (oral or injection) or at least a doubling from a stable maintenance oral
corticosteroid dose for at least 3 days
-- asthma-specific hospital admission
-- asthma-specific emergency department visit
Additional medication and/or medical intervention that would satisfy the CAE definition occurring within 7 days of the last day of a prior CAE event will be considered as part of the same event for analysis purposes. |
