- Proportion of participants who are in complete remission while off OCS for ≥ 2 months at Week 36 (FAS) [ Time Frame: Week 36 ]A binary response, whereby a responder is defined as a participant who is in complete remission while off OCS for ≥ 2 months at Week 36. Otherwise, a participant is a non-responder.
- Proportion of participants who remain relapse-free up to Week 36. [ Time Frame: Week 36 ]Relapse is defined as participants experiencing: 3 or more new lesions a per month (blisters, eczematous lesions, or urticarial plaques); or at least one large (> 10 cm diameter) eczematous lesion or urticarial plaques that do not heal within 1 week; or the extension of established lesions or daily pruritus in participants who have achieved disease control.
- Cumulative OCS exposure (mg/kg) from baseline to Week 36. [ Time Frame: Week 36 ]For each 4 weekly interval and for the sum of the 4-weekly intervals over the whole of the 36-week treatment period, and for the sum of the 4-weekly intervals over the initial 16-week treatment period, the model will be used to estimate the mean cumulative OCS exposure (mg/kg) for each treatment group and the difference versus placebo, with corresponding 95% confidence limits.
- Change from baseline in BPDAI activity score at Week 36. [ Time Frame: Week 36 ]Bullous Pemphigoid Disease Area Index is a clinician completed tool that is used for independent disease severity assessment to measure disease extent in BP. The BPDAI total activity and BPDAI damage give an indication of disease activity, with higher scores indicating greater disease activity or damage.
- Change from baseline in BPDAI-Pruritus score at Week 36. [ Time Frame: Week 36 ]The BPDAI-Pruritus is a separate component of the BPDAI that asks the participant to grade the severity of pruritus over the past 24 hours, the past week, and the past month. For each recall period, severity of pruritus is rated on an NRS ranging from 0 for no itch to 10 for maximal itching. The three scores are then summed for a total score ranging from 0 to 30.
- Proportion of participants in sustained complete/ partial remission on minimal OCS/ off OCS for at least 2 months at week 36 [ Time Frame: Week 36 ]
Sustained complete remission on minimal steroid therapy/off steroid therapy. The absence of new or established lesions or pruritus while the participant is on minimal steroid therapy/ off steroid therapy for at least 2 months:
Sustained partial remission: the presence of transient new lesions that heal within 1 week while the participant is on minimal steroid therapy or off steroid therapy for at least 2 months.
- Cumulative time (weeks) in complete remission off OCS from baseline to Week 36 [ Time Frame: Week 36 ]Complete remission off steroid therapy is defined as the absence of new or established lesions or pruritus while the participant is off steroid therapy for at least 2 months.
- Proportion of participants off OCS by Week 36. [ Time Frame: Week 36 ]The consolidation phase begins when disease control is achieved and continues until the time at which no new lesions or pruritic symptoms have developed for a minimum of 2 weeks and the majority of established lesions have healed (end of consolidation phase). At this point, participants will begin protocolled OCS tapering, with the aim to taper off OCS completely within 3 to 4 months (ie, 4 to 5 months from randomization).
- IGA Score at Week 36. [ Time Frame: Week 36 ]An IGA scale uses clinical characteristics to assess overall disease severity at any given time point. This scoring system allows clinicians to rate skin disease activity by general overall impressions. This IGA scale uses key signs of BP with ordinal levels of severity. The IGA is a 5-point categorical scale ranging from 0 (clear) to 4 (severe) with higher scores indicating greater disease activity or damage. The IGA uses clinical characteristics based on the number of lesions, blisters, erosions, erythema and number of anatomical locations.

- Cumulative OCS exposure (mg/kg) from baseline to Week 16. [ Time Frame: Week 16 ]For each 4 weekly interval and for the sum of the 4-weekly intervals over the whole of the 36-week treatment period, and for the sum of the 4-weekly intervals over the initial 16-week treatment period, the model will be used to estimate the mean cumulative OCS exposure (mg/kg) for each treatment group and the difference versus placebo, with corresponding 95% confidence limits.
- Proportion of participants who remain relapse-free up to Week 16. [ Time Frame: Week 16 ]Relapse is defined as participants experiencing: 3 or more new lesions a per month (blisters, eczematous lesions, or urticarial plaques); or at least one large (> 10 cm diameter) eczematous lesion or urticarial plaques that do not heal within 1 week; or the extension of established lesions or daily pruritus in participants who have achieved disease control.
- Proportion of participants with any clinical benefit (eg, partial and complete remission during taper, with no steroid use, or with minimal steroid use [ie, < 0.1 mg/kg/day]) at Week 16. [ Time Frame: Week 16 ]To assess partial and complete remission during taper, with no steroid use, or with minimal steroid use at week 16)
- Time to disease control, OCS dose (mg/kg) at disease control and time to the end of the consolidation phase. [ Time Frame: Week 16 ]
The time at which new lesions cease to form and established lesions begin to heal or pruritic symptoms start to abate.
During the first 8 weeks of the study, participants will be assessed every 2 weeks for disease Control. When disease control is achieved, this marks the beginning of the consolidation phase. The end of the consolidation phase is the point that corticosteroid tapering will be initiated.
- Change from baseline in BPDAI activity score at Week 16. [ Time Frame: Week 16 ]The total BPDAI activity score (0 to 360) is the arithmetic sum of the 3 subcomponents - cutaneous blisters/ erosions, cutaneous urticarial/ erythema, and mucosal blisters/ erosions
- Change from baseline in BPDAI-Pruritus score at Week 16. [ Time Frame: Week 16 ]The BPDAI-Pruritus is a separate component of the BPDAI that asks the participant to grade the severity of pruritus is rated on an NRS ranging from 0 to no itch to 10 for maximal itching.
- Serum benralizumab concentration. [ Time Frame: Weeks 0,2,4,6,8,16,24,36, 60 and 12 weeks after last IP dose ]To estimate the PK of benralizumab in participants with BP.
- Determination of Anti-drug antibodies (ADA) in serum [ Time Frame: Weeks 0,4,6,8,16,24,36, 60 and 12 weeks after last IP dose ]Blood samples for determination of ADA in serum will be assayed to assess immunogenicity of benralizumab.

Sex 7 Male or female.
Reproduction 8 Female participants capable of having children must meet both of the following conditions ([a] and [b]):
(a) Have a negative urine pregnancy test at screening and (b) Must agree to use a highly effective method of birth control (confirmed by the investigator) from randomization throughout the study duration and within 12 weeks after last dose of IP. Highly effective forms (those that can achieve a failure rate of less than 1% per year when used consistently and correctly) of birth control include: (i) Combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation - oral, intravaginal, or transdermal.
(ii) Progestogen-only hormonal contraception associated with inhibition of ovulation - oral, injectable, or implantable.
(iii) Intrauterine device. (iv) Intrauterine hormone-releasing system. (v) Bilateral tubal occlusion. (vi) Sexual abstinence, ie, refraining from heterosexual intercourse (the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the participant).
(vii) Vasectomized sexual partner provided that partner is the sole sexual partner of the female of childbearing potential (FOCBP) study participant and that the vasectomized partner has received medical assessment of the surgical success.
(c) Females not of childbearing potential are defined as females who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Females will be considered postmenopausal if they have been amenorrhoeic for ≥ 12 months prior to the planned date of randomization without an alternative medical cause. The following age-specific requirements apply: (i) Females < 50 years old will be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of exogenous hormonal treatment and follicle-stimulating hormone (FSH) levels in the postmenopausal range. Until FSH is documented to be within menopausal range, treat the participant as a female of childbearing potential.
(ii) Females ≥ 50 years old will be considered postmenopausal if they have been amenorrhoeic for 12 months or more following cessation of all exogenous hormonal treatment.
