About

The primary objective of this study is to evaluate the long-term safety and tolerability of litifilimab in participants with active systemic lupus erythematosus (SLE).

The secondary objectives of this study are to evaluate the long-term effect of litifilimab on disease activity in participants with SLE, to evaluate the long-term effect of litifilimab in participants with SLE in maintaining low disease activity, to evaluate the effect of litifilimab in participants with active SLE in preventing irreversible organ damage, to assess long-term use of oral corticosteroid (OCS) with participants receiving litifilimab treatment, to assess the impact of litifilimab on participant-reported Health-Related Quality-of-Life Questionnaire (HRQoL), symptoms, and impacts of SLE, to evaluate long-term effect of litifilimab on laboratory parameters, and to evaluate immunogenicity of litifilimab.

Full description

This is an extension study for all participants who completed study 230LE303 (NCT04895241) and 230LE304 (NCT04961567) (parent phase 3 studies) through Week 52 and did not discontinue litifilimab or placebo. Eligible participants from parent phase 3 studies will be followed for up to 180 weeks.

Inclusion and exclusion criteria

Key Inclusion Criteria:

  • Participants who completed 1 of the 52-week of the double-blind placebo-controlled, parent Phase 3 studies (230LE303 (NCT04895241) and 230LE304 (NCT04961567)) on study treatments with either litifilimab or placebo to Week 48 and attended the last study assessment visit at Week 52

Key Exclusion Criteria:

  • Early parent Phase 3 studies treatment terminators (participants who discontinued study treatment before Week 52)
  • Early parent Phase 3 studies terminators (participants who withdrew from study participation and did not complete the 52 week treatment period)
  • Participants who developed moderate-to-severe worsening of organ-specific lupus manifestations that would require a change in antimalarials and/or immunosuppressive therapy (initiation of new treatment or increase in dose above the allowed maximum dose)
  • Use of other investigational drugs or off-label drugs used to treat SLE, cutaneous lupus, or lupus nephritis during the parent Phase 3 studies

NOTE: Other inclusion/exclusion criteria may apply.

Litifilimab Low Dose
Experimental group
Description:
Participants who are receiving background nonbiologic lupus standard of care (SOC) therapy and received litifilimab low dose, subcutaneously (SC), every 4 weeks (Q4W) during the parent Phase 3 studies (i.e. studies 230LE303 \[NCT04895241\] or 230LE304 \[NCT04961567\]) will continue to receive litifilimab low dose, SC, Q4W from Day 1 up to 152 weeks with an additional dose of litifilimab-matching placebo at Week 2. Participants who are receiving background nonbiologic lupus SOC therapy and received litifilimab-matching placebo in the parent Phase 3 studies (i.e. studies 230LE303 \[NCT04895241\] or 230LE304 \[NCT04961567\]) will be randomized to receive litifilimab low dose, SC, Q4W from Day 1 up to 152 weeks with an additional dose at Week 2.
Treatment:
Drug: Litifilimab
Drug: Litifilimab-matching placebo
Litifilimab High Dose
Experimental group
Description:
Participants who are receiving background nonbiologic lupus SOC therapy and received litifilimab high dose, SC, Q4W during the parent Phase 3 studies (i.e. studies 230LE303 \[NCT04895241\] or 230LE304 \[NCT04961567\]) will continue to receive litifilimab high dose, SC, Q4W from Day 1 up to 152 weeks with an additional dose of litifilimab-matching placebo at Week 2. Participants who are receiving background nonbiologic lupus SOC therapy and received litifilimab-matching placebo in the parent Phase 3 studies (i.e. studies 230LE303 \[NCT04895241\] or 230LE304 \[NCT04961567\]) will be randomized to receive litifilimab high dose, SC, Q4W from Day 1 up to 152 weeks with an additional dose at Week 2.
Treatment:
Drug: Litifilimab
Drug: Litifilimab-matching placebo
