Query!
Assessment method [5]
0
0
Total DLQI scores range from 0 to 30 with higher DLQI scores reflecting greater impairment in a participant's health-related quality of life. The DLQI score is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired. The measure type mean is the estimated mean from adjusted MMRM.

Assessment method [6]
0
0
An adverse event is any untoward medical occurrence in a participant to whom a medicinal product is administered and which does not necessarily have a causal relationship with this treatment. A serious adverse event is an adverse event that results in death or is life-threatening or requires/prolongs hospitalization or results in persistent/significant disability/incapacity or congenital abnormality/birth defect. Adverse events of Grade 3 of higher are severe and life-threatening adverse events CS-related adverse events - causality as determined by the investigator.

Eligibility
Key inclusion criteria
* Confirmed diagnosis of PV within the previous 24 months, based on the presence of histological features of acantholysis via skin or mucosal biopsy and one of the following: tissue bound immunoglobulin G (IgG) antibodies by direct immunofluorescence on the surface of affected epithelium or serological detection of serum desmoglein-3 (DSg3) autoantibodies against epithelial cell surface either by indirect immunofluorescence microscopy or by enzyme-linked immunosorbent assay
* Presence of moderate-to-severely active disease, defined as overall PDAI activity score of greater than or equal to (>/=)15
* Receiving standard-of-care corticosteroids consisting of 60-120 mg/day oral prednisone or equivalent and, in the judgment of the investigator, expected to benefit from the addition of immunosuppressive therapy
* For women who are not postmenopausal (>/=12 months of non-therapy-induced amenorrhea) or surgically sterile (absence of ovaries and/or uterus): agreement to remain abstinent or use two effective methods of contraception, including at least one method with a failure rate of less than (<) 1 percent (%) per year, during the treatment period and for at least 12 months after the last dose of study treatment
Abstinence is acceptable only if it is in line with the preferred and usual lifestyle of the participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception
Barrier methods must always be supplemented with the use of a spermicide
Examples of contraceptive methods with a failure rate of < 1% per year (highly effective contraceptive methods) include tubal ligation, male sterilization, hormonal implants, established, proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices
* For men (including those who have undergone a vasectomy): agreement to remain abstinent or use a condom during the treatment period and for at least 12 months after the last dose of study treatment and agreement to refrain from donating sperm during this same period
Abstinence is only acceptable if it is in line with the preferred and usual lifestyle of the participant
Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception. In addition to male contraception, agreement to advise female partners of childbearing potential to use highly effective contraception during the study and for at least 12 months after the last dose of study treatment
* Agreement to avoid excessive exposure to sunlight during study participation
* Able to comply with the study protocol, in the investigator's judgment

Summary
Brief summary
This is a Phase III, randomized, double-blind, double-dummy, active-comparator, parallel-arm, multicenter study to evaluate the efficacy and safety of rituximab compared with MMF in participants with moderate-to-severely active PV requiring 60-120 milligrams per day (mg/day) oral prednisone or equivalent. Participants must have a confirmed diagnosis of PV within the previous 24 months (by skin or mucosal biopsy and immunohistochemistry) and evidence of active disease at screening. Approximately 135 participants will be enrolled at up to 60 centers worldwide. Participants will be randomized in a 1:1 ratio to receive either rituximab plus MMF placebo or rituximab placebo plus MMF. Randomization will be stratified by duration of illness. The study will consist of three periods: a screening period of up to 28 days, a 52-week double-blind treatment period, and a 48-week safety follow up period that begins at the time of study treatment completion or discontinuation.
