) affecting ≥ 35% or more of their body surface area (BSA), results from a small open-label maximum-use trial showed.
When approved for this age group, ruxolitinib cream will provide a topical nonsteroidal option for patients aged 2-11, which will “simplify the treatment regimen,” one of the study investigators, Linda Stein Gold, MD, director of clinical research and division head of dermatology at the Henry Ford Health System, Detroit, said in an interview after the Revolutionizing Atopic Dermatitis conference, where the study was presented during a late-breaking abstract session.
A topical formulation of the selective Janus kinase (JAK) 1/JAK2 inhibitor, ruxolitinib cream 1.5% is currently approved by the Food and Drug Administration for the short-term and noncontinuous chronic treatment of mild to moderate AD in non-immunocompromised adult and pediatric patients aged 12 years and older, whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable.
In previous reports of this trial in children aged 2-11 years with ≥ 35% affected BSA, ruxolitinib cream 1.5% was generally well tolerated, with rapid anti-inflammatory and antipruritic effects and improvements in patient-reported outcomes observed with ≤ 4 weeks of continuous treatment and maintained with as-needed treatment from 4 to 8 weeks.
For the current trial, investigators evaluated data on tolerability, safety, systemic exposure, and clinical and patient-reported outcomes through 52 weeks to determine whether clinical benefits and tolerability observed through 8 weeks were sustained.
Dr. Stein Gold and colleagues reported results from 29 children who received ruxolitinib cream 1.5% from baseline through week 8. Of these, 22 continued into the long-term safety period from week 8 through 52. From baseline through week 8, patients applied a mean of 6.5 g per day of ruxolitinib cream; this dropped to a mean of 3.2 g per day from weeks 8 through 52. The mean steady-state plasma concentration of ruxolitinib throughout the study was 98.2 nM, which is “well below half-maximal concentration of JAK-mediated myelosuppression in adults (281 nM),” the researchers stated in their abstract.
No treatment-related interruptions, discontinuations, or serious adverse events were observed between baseline and week 52. One patient (3.4%) had two treatment-related application site reactions (paresthesia and folliculitis). At weeks 4 and 52, 53.8% of patients achieved treatment success, which was defined as an Investigator Global Assessment of 0/1 with a ≥ 2-grade improvement from baseline. The mean affected BSA decreased from 58.0% at baseline to 11.4% at week 4 and continued to decrease to 2.2% through week 52. “I was surprised that patients could maintain control over the long-term using the medication as needed,” Dr. Stein Gold told this news organization. “I was also pleased to see that there was low systemic exposure even when used on large body surface areas.”
In other findings, the mean total Patient Oriented Eczema Measure score dropped from a baseline of 19.4 to a mean of 4.5 at week 8 and 3.6 at week 52 and the mean total Children’s Dermatology Life Quality Index score fell from a baseline of 15.4 to a mean of 5.3 at week 8 and a mean of 2.1 at week 52. Meanwhile, the mean total Infants’ Dermatology Quality of Life Index score fell from a mean of 12.3 at baseline to a mean of 2.8 at week 8 and a mean of 0.7 at week 52.
Dr. Stein Gold noted certain limitations of the study, including the fact that it did not study children aged younger than 2 years.
The study was funded by Incyte, which markets ruxolitinib cream 1.5% as Opzelura. Dr. Stein Gold disclosed that she has served as an investigator, advisor, and/or speaker for several pharmaceutical companies, including Incyte.
