Key inclusion & exclusion criteria

Inclusion criteria:
1.Male or female adults who have reached the age of consent in the applicable region (eg, =18 years in the US).
2.Clinical diagnosis of IgG4-RD.
3.Fulfillment of the 2019 ACR/EULAR classification criteria.
4.Experiencing (or recently experienced) an IgG4-RD flare that requires initiation or continuation of glucocorticoid (GC) treatment at the time of informed consent.
5.IgG4-RD affecting at least 2 organs/sites at any time in the course of IgG4-RD. One organ must meet the requirements for the ACR/EULAR classification criteria; the second organ is as defined by the investigator. 6.Non-sterilized male subjects who are sexually active with a female partner of childbearing potential must use a condom with spermicide (where spermicide is available) from Day 1 through to the end of the study and must agree to continue using such precautions for at least 6 months after the final dose of IP. Females of childbearing potential who are sexually active with a non-sterilized male partner must use a highly effective method of contraception

Health Condition(s) or Problem(s) studied

Immunoglobulin G4-related disease (IgG4-RD)
MedDRA version: 20.0 Level: PT Classification code 10077271 Term: Immunoglobulin G4 related disease System Organ Class: 10028395 - Musculoskeletal and connective tissue disorders

Therapeutic area: Diseases [C] - Immune System Diseases [C20]

Intervention(s)

Trade Name: Uplizna
Product Name: Inebilizumab
Pharmaceutical Form: Concentrate for solution for infusion
INN or Proposed INN: INEBILIZUMAB
Current Sponsor code: MEDI-551
Other descriptive name: afucosylated IgG1 kappa monoclonal antibody
Concentration unit: mg/ml milligram(s)/millilitre
Concentration type: equal
Concentration number: 10-
Pharmaceutical form of the placebo: Concentrate for solution for infusion
Route of administration of the placebo: Intravenous use

Primary Outcome(s)

Secondary Objective: .To evaluate the safety and tolerability of inebilizumab in patients with IgG4-RD.
.To evaluate the effect of inebilizumab on other measures of disease activity

Timepoint(s) of evaluation of this end point: 52-week RCP

Main Objective: To evaluate the efficacy of inebilizumab in reducing the risk of a disease flare in patients with IgG4-RD

Primary end point(s): Time to disease flare, defined as the time in days from Day 1 (dosing) to the date of the first treated and AC-determined IgG4 RD flare within the 52-week RCP. The date of disease flare is defined as the date of initiation of any flare treatment (new or increased GC treatment, other immunotherapy, or interventional procedure) deemed necessary by the Investigator for the flare.

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: 52-week RCP

Secondary end point(s): .Incidence of TEAEs, TESAEs, and treatment-emergent adverse events of special interest (AESIs) during the 52-week RCP and during the OLP.
.The incidence of ADAs directed against inebilizumab during the RCP.
.Annualized flare rate for treated and AC-determined flares during the RCP.
.Annualized flare rate for AC-determined flares, whether or not treated, during the RCP.
.The proportion of subjects achieving flare-free complete remission at Week 52. Complete remission is defined as an IgG4-RD Responder Index (RI, Wallace et al, 2018) score of 0 at Week 52, no AC-determined flare during the RCP, and no treatment for flare or disease control except the required 8-week GC taper.
.Time to initiation of first treatment (medication or procedure) for new or worsening disease activity by the Investigator within the RCP, regardless of AC determination of flare.
.Glucocorticoid use, calculated as the cumulative GC dose taken for the purpose of IgG4-RD disease control during the RCP.
