Efficacy and Safety of Frexalimab (SAR441344) in the Treatment of Systemic Lupus Erythematosus

Study Purpose

This is a multinational, randomized, placebo-controlled, parallel treatment, Phase 2, double-blind, 2 arm study evaluating the efficacy and safety of SAR441344 in comparison with placebo in the treatment of participants aged 18 to 70 years with active Systemic Lupus Erythematosus (SLE). Study details include:

- Study duration: 36 weeks.

- Treatment duration: 24 weeks.

- Visit frequency: every 2 weeks

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 70 Years
Gender	All
