Percent Change From Baseline (PCFB) in Eczema Area and Severity Index (EASI) Score at Week 12 in Group 1
Baseline (Day 1) and at Week 12

EASI scoring system is standardized clinical tool for assessment of extent (area) and severity of atopic dermatitis (AD). Severity of clinical signs of AD (erythema, induration/papulation, excoriation and lichenification) scored separately for each of 4 body regions (head and neck, upper limbs, trunk and lower limbs on 4-point scale: 0= absent; 1= mild; 2= moderate; 3= severe. EASI area score was based upon % body surface area with AD in body region: 0 (0%), 1=1-9%; 2=10-29%; 3=30-49%; 4=50-69%; 5=70-89%; 6=90-100% The final EASI score was obtained by weight-averaging these 4 scores and scores ranged from 0 to 72, with higher scores= more severe or extensive condition. Posterior Median presented from Bayesian analysis under the hypothetical strategy. The percent change from baseline in the EASI score at week 12 in group 1 is reported here. Data reported as 'Median' refers to 'Posterior Median' and '95% Confidence Interval' refers to '95% Credible Interval'.

GSK1070806 or placeboEXPERIMENTALThis is a single dose escalating study. On enrolment into the study, each subject will be assigned to a group. These groups will be aligned to specific dose levels of GSK1070806. All subjects will be randomised to receive either a single intravenously administered dose of GSK1070806 or matching placebo (saline). The randomisation is generated by GSK prior to study start.

Frequently asked questions about Aletekitug

What is Aletekitug used for?

Aletekitug is an investigational monoclonal antibody being developed for the treatment of ulcerative colitis, specifically moderate to severe cases. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

Who makes Aletekitug?

Aletekitug is being developed by GSK plc, a global biopharmaceutical company listed on the stock exchange under the ticker GSK. The drug is in early-stage clinical trials for ulcerative colitis.

What phase is Aletekitug in?

Aletekitug is in Phase 1 clinical development. It is an investigational drug, meaning it has not yet been approved for any use. Two Phase 1 trials are planned but have not yet started recruiting participants.

What clinical trials is Aletekitug in?

Aletekitug is involved in two Phase 1 trials: NCT07747467, a study of multiple interventions in moderate to severe ulcerative colitis, and NCT07747480, a substudy focusing on Aletekitug alone. Both trials are not yet recruiting and each plans to enroll 16 participants.

Is Aletekitug the same as GSK1070806?

Yes, Aletekitug is also known as GSK1070806. Both names refer to the same investigational monoclonal antibody being studied for ulcerative colitis.
