Study details include a screening period (4 weeks and not less than 11 days before Day 1), a treatment period (12 weeks ± 3 days) and a post-treatment period (safety follow-up) (2 weeks ± 3 days). The total number of study visits will be 7.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of participants with a 75% or greater PASI score (Psoriasis Area and Severity Index score) improvement (reduction) from baseline (PASI75) at week 12	The PASI is a tool that provides a numeric scoring for participants' overall psoriasis disease state, ranging from 0 (no disease) to 72 (maximal disease). It is a linear combination of percent of surface area of skin (A) that is affected (1 [<10%] to 6 [90% - 100%]) and the severity of erythema [E], induration [I], and desquamation [D] on a scale from 0=no symptoms to 4=very marked over four body regions : head (h), trunk (t), upper extremities (u) and lower extremities (l).; The PASI score is calculated according to the following formula: PASI = 0.1(Eh+Ih+Dh)Ah + 0.3(Et+It+Dt)At + 0.2(Eu+Iu+Du)Au + 0.4(El+Il+Dl)Al	Baseline to Week 12
Secondary	PASI change from baseline to week 12		Baseline to week 12
Secondary	Proportion of participants with static Psoriasis Global Assessment (sPGA) score 0 (complete clearance) or 1 (minimal disease) from baseline to week 12	The sPGA is a 5-point score ranging from 0 to 4, based on the physician's assessment of the average thickness, erythema, and scaling of all psoriatic lesions. A lower score indicates less body coverage, with 0 being clear and 1 being almost clear.	Baseline to week 12
Secondary	Number of participants with Treatment-Emergent Adverse Events (TEAEs), serious AEs (SAEs), and AEs of special interest (AESIs)	Incidence of treatment-emergent AEs (TEAEs), serious AEs (SAEs), and AEs of special interest (AESIs).	Baseline to week 14
Secondary	Plasma pre-dose concentrations of SAR441566		Week 2 to week 12
Secondary	Plasma post-dose concentrations of SAR441566		Week 0 to week 12
