Study summary

This was a Phase 2, international, multicenter, randomized, double-blind, placebo-controlled, dose-ranging, 12-week study. It was designed to assess the therapeutic dose, efficacy, and safety of treatment with SAR441566 in male and female adults with moderate to severe plaque psoriasis. Study details included 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) (4 weeks ± 3 days). The total number of study visits was 7.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Percentage of Participants With a 75% or Greater Psoriasis Area and Severity Index (PASI) Score Reduction From Baseline (PASI75) at Week 12

    PASI is linear combination of percent of surface area of skin that is affected and severity of erythema(E),induration(i),desquamation(D) over 4 body regions: head(h),trunk(t),upper extremities(u),lower extremities(l). The signs of severity, E, i and D of lesions are assessed using numeric scale for which scores are made independently for each of the areas; range:0 (complete lack of cutaneous involvement) to 4 (severest possible involvement). For each body area, percentage of considered body area covered by plaque psoriasis is translated into numerical value "Ax":0=no involvement,1=\<10% to 6=90 to 100% involvement. These scores are noted Ah, At, Au, and Al in formula below. 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. PASI score range:0 (no disease) to 72 (maximal disease);higher scores: greater psoriasis severity. Percentage of participants with PASI75 at Week 12 is presented.

    Time frame: Baseline (Day 1) and Week 12

Secondary outcomes

  1. Percent Change From Baseline in Psoriasis Area and Severity Index to Week 12

    PASI is linear combination of percent of surface area of skin that is affected and severity of E, i, D over 4 body regions: h, t, u, l. The signs of severity, E, i and D of lesions are assessed using numeric scale for which scores are made independently for each of the areas; range: 0 (complete lack of cutaneous involvement) to 4 (severest possible involvement). For each body area, percentage of considered body area covered by plaque psoriasis is translated into numerical value "Ax": 0= no involvement,1= \<10% to 6 =90 to 100% involvement. These scores are noted Ah, At, Au, and Al in formula below. 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. The PASI score ranges from 0 (no disease) to 72 (maximal disease); higher scores indicate greater psoriasis severity. Baseline was defined as last available value before the first dose of study treatment.

    Time frame: Baseline (Day 1) to Week 12

  2. Percentage of Participants With Static Psoriasis Global Assessment (sPGA) Score 0 (Complete Clearance) or 1 (Minimal Disease) at Week 12

    sPGA is 5-point score based on average thickness,erythema,and scaling of all psoriatic lesions.Score ranges:E:0(normal) to 4(bright to deep red coloration of lesions); i (plaque elevation):0(none) to 4(severe thickening with hard edges; D:0(no scaling) to 3(moderate scaling).Overall scoring: average of E,i,D;range:0(clear)= 0 for all 3 symptoms; 1(almost clear)=mean \>0, \<1.5, normal to pink coloration, just detectable(possible slight elevation),no to minimal focal scaling; 2(mild)= mean \>= 1.5, \<2.5, pink to light red coloration, mild thickening, predominantly fine scaling; 3(moderate)= mean \>=2.5,\<3.5, dull to bright red coloration, clearly distinguishable to moderate thickening, moderate scaling; 4(severe)= mean \>=3.5,bright to deep dark red coloration,severe thickening with hard edges,severe coarse scaling covering almost all or all lesions.Lower score:less body coverage,with 0:complete clearance and 1:minimal disease. Total participants who received score of 0 and 1 are reported.

    Time frame: Baseline (Day 1) and Week 12

  3. Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Treatment-Emergent Serious Adverse Events (TESAEs), Treatment-Emergent Adverse Events of Special Interest (TEAESIs), Study Treatment Discontinuation and Study Withdrawals Due to TEAEs

    An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study treatment, whether considered related to the study treatment. An SAE was defined as any untoward medical occurrence that, at any dose, resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or was an important medical event. TEAEs were AEs that developed, worsened or became serious during the TE period. An AESI was an AE (serious or non-serious) of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring and immediate notification by the Investigator to the Sponsor was required.

    Time frame: From first dose of study treatment (Day 1) up to 5 days post last dose of study treatment, up to 102 days

  4. Pre-Dose Plasma Concentration of SAR441566

    Blood samples were collected at indicated timepoints for the assessment of pre-dose plasma concentration of SAR441566.

    Time frame: 1 hour pre-dose on Weeks 2, 4, 8 and 12

  5. Post-Dose Plasma Concentration of SAR441566

    Blood samples were collected at indicated timepoints for the assessment of post-dose plasma concentration of SAR441566.

    Time frame: 2.5 to 3.5 hours post-dose on Day 1, Weeks 2, 4, 8 and 12
