Fase 2a undersøgelse af effektivitet og sikkerhed af OpSCF ved moderat til svær atopisk dermatitis
Et randomiseret, dobbeltblindt, placebokontrolleret, fase 2a-studie til evaluering af effektiviteten og sikkerheden af OpSCF ved behandling af voksne forsøgspersoner med moderat til svær atopisk dermatitis
Formålet med denne undersøgelse er at bestemme effektiviteten og sikkerheden af et monoklonalt antistof, OpSCF, til behandling af voksne med moderat til svær atopisk dermatitis (Eksem). OpSCF vil blive sammenlignet med en placebo.
OpSCF eller placebo vil blive administreret hver anden uge i 14 uger, og effekten vil blive vurderet to uger senere. Derefter kan forsøgspersoner vælge at gå ind i en Open Label Extension-fase, hvor alle forsøgspersoner vil modtage OpSCF hver 4. uge i yderligere 40 uger.

Percent Change From Baseline in Eczema Area and Severity Index (EASI) at Week 16
Tidsramme: Baseline, Week 16
|
The EASI quantifies the severity of a participant's AD based on both lesion severity and the % of body surface area (BSA) affected.
Severity of clinical signs of AD lesions (erythema [E], induration/papulation[I], excoriation[Ex] & lichenification[L]) was scored separately for each of 4 body regions[head(h), upper extremities(u), trunk(t), lower extremities(l)] on a 4-point scale:0= absent; 1= mild;2= moderate;3= severe.
EASI area score was based on % BSA with AD in body region: 0(no involvement), 1(< 10%),2 (10 to <30%), 3(30 to <50%), 4(50 to <70%), 5(70 to <90%) and 6(90 to 100%).
The EASI score is obtained as: EASI(A) = 0.1*(Eh+Ih+Exh+Lh)*Ah + 0.2*(Eu+Iu+Exu+Lu)*Au + 0.3*(Et +It+Ext+Lt)*At + 0.4*(El+Il+Exl+Ll)*Al.
Total EASI score = 0.0 to 72.0; higher scores indicate greater severity of AD.
Here, a negative change from baseline indicates less severity in AD.

Number of Participants Who Experienced At-Least One Treatment Emergent Adverse Event (TEAE) and Serious Adverse Events (SAEs)
Tidsramme: From first dose of study drug up to end of follow-up (up to Week 67)
|
An adverse event (AE) was any untoward medical occurrence in participant administered a pharmaceutical product & that does not necessarily have a causal relationship with this treatment.
It can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study product, whether or not considered related to the study product.
An SAE was any untoward medical occurrence that, at any dose resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization resulted in persistent or significant disability/incapacity & was a congenital anomaly/birth defect.
Any AE starting on or after the first dose date will be considered TEAE.

PP-NRS is based on the Numeric Rating Scale which was used to assess the level of itch the participant was experiencing.
The following question was asked to participants: "On a scale of 0 to 10, with 0 = "no itch" and 10 = "worst itch imaginable", how would you rate your itch at the worst moment during the previous 24 hours?"
Based on the score provided by participant, the PP-NRS score was assigned.
Higher score indicates more severity.
A negative change from baseline indicates improvement.

The overall BSA affected by AD was evaluated (from 0% to 100%).
It was calculated using the palm surface area method.
This method states that palmar surface of 1 hand (using the participant's hand and including the fingers) represents 1% of his or her total BSA.

ADCT questionnaire is a self-assessment comprised of 6 concise questions to evaluate participant's perceptions of AD symptoms and impacts on their life and function over the last week.

POEM is a self-assessment of disease severity using 7 questions asked to participant.
A maximum value of 28 can be assigned based on the participant's response to 7 questions scored from 0 to 4, where 0 = No days, 1 = 1-2 days, 2 = 3-4 days, 3 = 5-6 days and 4 = Every day.
Higher score indicates high severity.

DLQI is a 10 questions questionnaire to measure how much skin problems have affected a participant's life over the last week.
Each question is scored from 0 to 3 (0 = Not at all, 1 = A little, 2 = A lot and 3 = Very much).
The DLQI is calculated by summing the score of each question, giving a total score ranging from 0 (not at all) to 30 (very much).
The higher the score the more quality of life is impaired.
A negative change from baseline indicates improvement in QoL.
