What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests bimekizumab, a medication designed to treat moderate to severe hidradenitis suppurativa (HS), a chronic skin condition that causes painful lumps under the skin. The study's main goal is to assess the long-term safety of bimekizumab. Participants will be assigned to one of two different dosing regimens. The trial seeks individuals who have completed a previous bimekizumab study for HS without major issues. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants the opportunity to contribute to the potential availability of a new treatment.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it mentions that ongoing or planned use of certain treatments for hidradenitis suppurativa (HS) or other conditions might be prohibited. It's best to discuss your current medications with the study team.

Is there any evidence suggesting that this treatment is likely to be safe for humans?

Research has shown that bimekizumab is generally safe for people with moderate to severe hidradenitis suppurativa (HS). In one study, patients experienced no new safety issues over a year, and most found the treatment manageable. Another study found that after two years, bimekizumab remained effective, and side effects were controlled. These results suggest that bimekizumab might be safe for long-term use in treating HS. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard treatments for hidradenitis suppurativa, which mainly include antibiotics and biologics like adalimumab, bimekizumab targets both interleukin-17A and interleukin-17F. This dual targeting could potentially offer a more comprehensive approach to reducing inflammation and lesions. Researchers are excited because this mechanism might provide better symptom control and improve the quality of life for patients who don't respond well to existing therapies.

What evidence suggests that bimekizumab might be an effective treatment for hidradenitis suppurativa?

Research has shown that bimekizumab effectively treats hidradenitis suppurativa (HS). Studies have found that it provides lasting symptom relief and helps control the disease over time. Patients often experience pain relief within two weeks, which continues throughout the treatment. After two years, more than half of the patients had only mild symptoms. The treatment has proven both effective and safe, with consistent results over three years. Participants in this trial will receive one of two different bimekizumab dosing regimens to further evaluate its effectiveness and safety. ^{1 2 3 6 7}

Trial Overview

The trial is testing the long-term safety of Bimekizumab in treating moderate to severe hidradenitis suppurativa. It's an extension study for those who've already been on Bimekizumab during earlier trials.

How Is the Trial Designed?

Group I: Bimekizumab dosing regimen 2 Experimental Treatment 1 Intervention

Subjects participating in the study will receive assigned bimekizumab dosing regimen 2 during the open-label extension period.

Group II: Bimekizumab dosing regimen 1 Experimental Treatment 1 Intervention

Subjects participating in the study will receive assigned bimekizumab dosing regimen 1 during the open-label extension period.

Bimekizumab is already approved in European Union, United States for the following indications:

Published Research Related to This Trial

Adalimumab and infliximab are the most studied treatments for moderate to severe hidradenitis suppurativa (HS), with clinical trials showing their efficacy, while other agents like anakinra and ustekinumab also demonstrate promise.

Adalimumab is currently the only biologic approved by the FDA for HS, and most treatments have a good safety profile, although infections are the most common side effect reported.

Systematic review of immunomodulatory therapies for hidradenitis suppurativa. Lim, SYD., Oon, HH.[2020]

In patients with severe hidradenitis suppurativa (HS), there is an increase in specific inflammatory monocytes and a unique cytokine profile, indicating a complex immune response that could guide treatment choices.

Treatment with etanercept, a TNF blocker, showed clinical improvement linked to increased production of IL-1β and IL-17 in blood cells, suggesting that monitoring these cytokines could help predict treatment outcomes.

Compartmentalized Cytokine Responses in Hidradenitis Suppurativa. Kanni, T., Tzanetakou, V., Savva, A., et al.[2018]

IL-17 inhibitors, particularly secukinumab and brodalumab, show promising efficacy in treating hidradenitis suppurativa (HS), with response rates of 57.1% and 100% respectively among 128 patients studied.

These treatments can be effective for patients who do not respond to other therapies, highlighting the need for standardized outcome measures to improve future research and clinical practices.

Treatment Outcomes of IL-17 Inhibitors in Hidradenitis Suppurativa: A Systematic Review. Kashetsky, N., Mufti, A., Alabdulrazzaq, S., et al.[2022]

A systematic review of 34 publications involving 105 patients with hidradenitis suppurativa (HS) found that TNF-alpha inhibitors, particularly infliximab, led to positive treatment outcomes in 90% of cases, indicating their potential efficacy in managing this challenging skin condition.

While side effects were reported in 8 out of 105 patients, they were similar to those seen in other studies with TNF-alpha inhibitors, suggesting a manageable safety profile; however, the need for more standardized reporting and randomized controlled trials is emphasized to better understand long-term effects and optimal treatment strategies.

In a phase II study involving 243 patients with moderate-to-severe hidradenitis suppurativa (HS), risankizumab did not meet the primary endpoint of achieving HS Clinical Response (HiSCR) at week 16, indicating it may not be an effective treatment for this condition.

The safety profile of risankizumab was generally favorable, with low rates of treatment-emergent adverse events across all treatment groups, suggesting that while it may not be effective, it is also not associated with significant safety concerns.

In a review of 12 randomized controlled trials involving 2915 patients, adalimumab and bimekizumab were found to be effective treatments for moderate-to-severe hidradenitis suppurativa, showing significant improvement in clinical response compared to placebo at 12-16 weeks.

All evaluated biologics, including adalimumab, bimekizumab, and secukinumab, demonstrated similar safety profiles with no increased risk of adverse effects compared to placebo, making them viable options for patients with refractory hidradenitis suppurativa.
