Exclusion criteria
Exclusion criteria: Disease related (BP) Exclusion criteria 1. Patients with severe BP where severe disease is defined as global BPDAI = 56. 2. Patients with refractory BP. Refractory BP may be defined as failure or loss of response to maximal doses of topical or oral steroids. 3. Suspected drug induced BP. 4. Concomitant skin conditions preventing physical evaluation of BP. rVA576 and Mometasone related exclusion criteria 5. Participation in a clinical trial of an investigational product within 6 weeks of screening. 6. Known hypersensitivity to tick or to rVA576 and any of its excipients. 7. BP patients on systemic corticosteroid or systemic immunomodulator treatment (including azathioprine, dapsone, rituximab etc). 8. Treatment with any biologics (e.g. etanercept, adalimumab, ustekinumab, infliximab, intravenous immunoglobulins (IVIG) and rituximab or other anti-CD20 therapies) within its 5 half-lives from screening. 9. Known hypersensitivity to mometasone furoate or to other corticosteroids or to any of the excipients in mometasone furoate 10. Received rVA576 or any other recognised systemic medications for the treatment of the current episode of BP prior to study entry. Prior topical treatment with corticosteroids is permitted. This must be discontinued and study medications started on Day 1 General Exclusion Criteria 11. Patients with severe medical or surgical conditions at screening or baseline including, but not limited to cardiac, respiratory, renal, hepatic haematological, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, cerebral, psychiatric, or any other severe acute or chronic medical condition that may increase the risk associated with study participation/treatment or may interfere with the interpretation of study results and, in the Investigator's opinion, would make the patient inappropriate for study entry. 12. Presence of any malignancy that has been under active treatment or in previous 5 years with the exception of patients with removal of uncomplicated basal cell carcinoma or cutaneous squamous cell carcinoma, who may take part in the study. 13. Congenital or acquired immunodeficiency (e.g. common variable immunodeficiency, organ transplantation). 14. Clinically significant vital sign measurements or ECG findings as determined by the Investigator. 15. Clinically significant abnormal laboratory test results including but not limited to: • Haemoglobin level 1200 x 10*9/L • Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >3 x the upper limit of normal (ULN) • Alkaline phosphatase >3 x ULN • Serum creatinine >2 x ULN 16. Active or recent history of clinically significant infection within 1 month of screening. 17. Pregnant or breast-feeding, or planning to become pregnant during the study. 18. Evidence of an active disease of hepatitis B (HBsAg positive or HBcAb positive) or hepatitis C (HCV ab positive), CMV (IgM positive) or human immunodeficiency virus (HIV) infection (HIV1/2 Ab positive 19.

| Main Objective: The primary objective of the study is to assess the safety of rVA576 in adult subjects with mild to moderate BP.;Secondary Objective: To assess the efficacy of rVA576 and its effect on the quality of life of adult subjects with mild to moderate BP.;Primary end point(s): Proportion of participants reporting grade 3, 4 and 5 adverse events, which are related/possibly related to rVA576 during the treatment period. The Common Terminology Criteria for Adverse Events (CTCAE v4.03) will be used to grade adverse events. At each study visit, participants will be questioned about adverse events they have experienced since the last study visit.;Timepoint(s) of evaluation of this end point: - Percentage change in BPDAI between baseline (Day1) and Day 42 - Mean absolute change in BPDAI between Day 1(baseline) and Day 42. compared to Day 1 - Proportion of patients whose BPDAI score decreases by 4 or more points between baseline (Day 1) and Day 42. - Proportion of patients whose BPDAI score increases by 3 or more points between baseline (Day 1) and Day 42. - Mean change in Dermatology Life Quality Index (DLQI) between baseline (Day 1) and Day 42 -Mean change in Treatment of Autoimmune Bullous Disease Quality of Life (TABQOL) baseline (Day 1) and Day 42 | — |
