NORTH CHICAGO, Ill., Jan. 8, 2024 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced Phase 2 results showing adults with moderate to severe hidradenitis suppurativa (HS) who had previously failed anti-TNF therapy who received lutikizumab (ABT-981) 300 mg every other week or 300 mg weekly achieved higher response rates (59.5 percent, nominal p=0.027 and 48.7 percent, nominal p=0.197, respectively) than placebo (35.0 percent) in the primary endpoint of achieving HS Clinical Response (HiSCR 50) at week 16. Based on these data, AbbVie will advance its clinical program of lutikizumab in HS to Phase 3.1,2
Lutikizumab is AbbVie’s investigational, dual-variable-domain interleukin (IL) 1α/1β antagonist. Studies have shown IL 1α and 1β are elevated in HS lesions.8
“AbbVie continues to pioneer research in the pursuit of new treatment options for patients with hidradenitis suppurativa, a frequently overlooked, underserved, and often suffering patient population,” said Roopal Thakkar, M.D., senior vice president, chief medical officer, global therapeutics, AbbVie. “These results help us further understand the use of lutikizumab in adults with moderate to severe hidradenitis suppurativa, and we will continue to apply our more than 25 years of expertise in immune-mediated diseases in advancing our clinical program for lutikizumab in HS to Phase 3.”
This study was a 16-week, Phase 2, randomized, double-blind, parallel group, placebo controlled, dose-ranging, multicenter study that evaluated the safety and efficacy of lutikizumab in 153 adult patients with moderate to severe HS who had previously failed anti-TNF therapy. Most patients (70.6 percent) had severe baseline Hurley Stage 3 disease – the most extensive form of HS – characterized by scarring, lesions and sinus tracts. Patients were randomized at baseline to receive one of three subcutaneous doses of lutikizumab (100 mg every other week, 300 mg every other week, or 300 mg every week) or placebo. The study’s primary endpoint was an achievement of HiSCR 50 at week 16, and the secondary endpoint was skin pain NRS30 at week 16 among subjects with baseline NRS≥3.1
In addition to achieving higher response rates in the primary endpoint and despite most patients having severe disease, the trial also showed patients receiving lutikizumab 300 mg weekly and 300 mg every other week achieved higher rates of improved skin pain via NRS30 and HiSCR75, a higher threshold of HS clinical response, compared to placebo. Lutikizumab 100 mg every other week did not show greater efficacy compared to placebo.1
Results from select endpoints are as follows:
| Endpoints (All at Week 16) | Response | Response (%); Treatment Diff vs. PBO# P-value+1 | |||
| PBO (N=40) | Luti 100 mg EOW (N=37) | Luti 300mg EOW (N=37) | Luti 300mg EW (N=39) | ||
| Primary | HiSCR 50 | 35.0 | 27.0 ∆: -9.7 p=0.345 | 59.5 ∆: 24.1 p=0.027 | 48.7 ∆: 13.8 p=0.197 |
| Secondary | Skin Pain NRS30* | N=31 12.9 | N=27 22.2 ∆: 9.4 p=0.330 | N=29 34.5 ∆: 21.8 p=0.039 | N=23 34.8 ∆: 19.8 p=0.066 |
| Additional | HiSCR 75 | 17.5 | 16.2 ∆: -2.2 p=0.795 | 45.9 ∆: 28.2 p=0.005 | 38.5 ∆: 21.0 p=0.031 |
| #Cochran-Mantel-Haenszel test adjusted for the stratification factor (Baseline Hurley Stage <3 and 3) |
All doses were generally well-tolerated. The percentage of subjects with treatment-emergent adverse events (TEAE) were generally similar across combined lutikizumab treatment arms (70.8 percent) and placebo (75.0 percent) with the most common being HS (10.6 percent), diarrhea (8.8 percent), headache (8.8 percent), pruritus (6.2 percent), contact dermatitis (5.3 percent), eczema (5.3 percent), and nasopharyngitis (5.3 percent) in the combined lutikizumab treatment group. Serious adverse events (SAEs) occurred in 5.3 percent of the combined lutikizumab treatment group and in 2.5 percent in the placebo group. There were no deaths, no events of neutropenia reported, and no Grade 3 or 4 laboratory evaluations of neutropenia observed. Throughout the study, one event of serious infection (infected stoma) was reported in lutikizumab 300 mg every other week, with no associated neutropenia, deemed by the investigator as having no reasonable possibility of being related to study drug. There was one instance of T-cell lymphoma (lutikizumab 300 mg every week) reported in a patient with pre-existing risk factors, including HS9 and ongoing cigarette smoking. There were no dose-dependent trends in any TEAEs, SAEs, infections, or serious infections.
“The burdens of HS are high and include long times to diagnosis, significant pain, disability, isolation, and reduced quality of life,” said Alexa B. Kimball, M.D., MPH, a study investigator from Beth Israel Deaconess Medical Center in Boston and Professor of Dermatology, Harvard Medical School.10,11,12 “These results are encouraging and help us further understand the use of lutikizumab in patients with HS as we work to address the need for additional treatment options for patients living with this disease.”
HiSCR 50 at week 16, the primary endpoint of this study, is a measure that represents patients who achieve at least a 50 percent reduction at week 16 in the total abscess and inflammatory nodule (AN) count with no increase in abscess count and no increase in draining fistula count relative to baseline. Similarly, HiSCR 75 represents the achievement of at least a 75 percent reduction in AN count at week 16 with no increase in draining fistula count relative to baseline. The secondary endpoint, NRS30 at week 16, defines the achievement of at least a 30 percent reduction and at least 1-unit reduction from baseline in NRS (Numeric Rating Scale) at week 16 as assessed by patient global assessment for skin pain, among subjects with baseline NRS≥3.13
These data will be presented at a future medical congress. Additional information about the program can be found on clinicaltrials.gov under the identifier NCT05139602.2
About Hidradenitis Suppurativa
Hidradenitis Suppurativa, sometimes referred to as “acne inversa” by dermatologists, is an inflammatory, chronic, recurrent, progressive disease that causes irreversible skin damage and disability due to the formation of painful cysts, abscesses and draining fistula.3,4,5,6,7 While advances in treatment have been made, limited treatment options are available. Globally, HS affects up to 1 percent of the population14 and can take on average 7-10 years for a person to be diagnosed.15,16
About Lutikizumab (ABT-981)
Lutikizumab (ABT-981) is a dual-variable-domain interleukin (IL) 1α/1β antagonist being investigated in several immune-mediated diseases, including HS and ulcerative colitis. Studies have shown IL 1α and 1β are elevated in HS lesions.8 Lutikizumab is an investigational agent and is not approved by regulatory authorities. Safety and efficacy have not been established.
