What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new oral treatment called SAR444656 (also known as KT-474 or KYM-001) for individuals with moderate to severe hidradenitis suppurativa, a chronic skin condition causing painful lumps under the skin. The study aims to evaluate the effectiveness and safety of this treatment compared to a placebo. Participants will be divided into three groups: one taking a lower dose of the treatment, another taking a higher dose, and a third taking a placebo. Eligible participants must have had hidradenitis suppurativa for at least a year, affecting at least two body areas, and must not have responded well to antibiotics. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop taking your current medications. However, you cannot have any active or chronic infections requiring systemic treatment within 30 days before starting the trial, and you must not have used prescription topical therapies for HS within 14 days before the trial begins.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that SAR444656, also known as KT-474, has undergone safety testing in earlier studies. In a previous trial, researchers evaluated this treatment in a controlled setting to assess its safety for people. The main focus of that study was safety, and the treatment was generally well-tolerated.

Reports from that study indicated that while some side effects occurred, they were mostly mild. Commonly reported issues included headaches and mild stomach discomfort. No serious side effects were linked to the treatment, which is a positive indicator for safety.

SAR444656 is also being studied for multiple conditions, suggesting ongoing confidence in its safety. This current study is in Phase 2, indicating that earlier trials demonstrated enough safety and potential benefits to continue research. While more information will emerge from ongoing studies, existing data supports that SAR444656 is relatively safe for human use. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for HS?

Most treatments for Hidradenitis Suppurativa, like antibiotics or biologics, focus on reducing inflammation. But SAR444656 offers something new. Researchers are excited about SAR444656 because it targets a different pathway in the body, potentially addressing the underlying causes of the condition more effectively. This oral treatment could offer a more convenient and less invasive option compared to injectable biologics, making it a promising alternative for those struggling with this chronic skin condition.

What evidence suggests that this trial's treatments could be effective for Hidradenitis Suppurativa?

Research shows that SAR444656, also known as KT-474, reduces inflammation by breaking down a protein called IRAK4. This protein is linked to inflammation, and lowering its levels can decrease inflammatory cytokines, which cause symptoms in conditions like hidradenitis suppurativa (HS). Early results suggest that this method might effectively treat HS by controlling inflammation. Previous studies with patients who have HS and atopic dermatitis showed promising results in reducing inflammation. Participants in this trial will receive either SAR444656 at one of two different doses or a placebo to evaluate its effectiveness in treating HS. ^{1 2 4 6 7}

Are You a Good Fit for This Trial?

Inclusion Criteria

I have HS lesions in at least 2 different areas, with one area being moderate or severe.

I have tried an oral antibiotic for HS for 3 months without improvement.

I am willing and able to keep a diary for the study.

Published Research Related to This Trial

A novel lotion containing triethyl-citrate, ethyl-linoleate, and g-peptide-10 was tested on 30 patients with mild to moderate hidradenitis suppurativa (HS) for eight weeks, showing significant improvement in both the Sartorius score and lesion counts.

The lotion was found to be effective and well-tolerated, with no reported side effects, making it a promising alternative to traditional antibiotic treatments that can lead to resistance.

Adalimumab administered weekly is effective for treating hidradenitis suppurativa (HS), showing a significant reduction in Dermatology Life Quality Index (DLQI) scores compared to placebo, with a difference of 2.8 points.

Infliximab also shows moderate-quality evidence of benefit for HS, but evidence for other treatments is less robust or lacking, making it difficult to draw further conclusions about their effectiveness.

Interventions for Hidradenitis Suppurativa: Updated Summary of an Original Cochrane Review. Ingram, JR.[2018]

In a retrospective study of 6 patients with severe hidradenitis suppurativa, infliximab monotherapy led to significant improvements in symptoms, including reduced exudation and fewer lesions over a 6-month follow-up period.

The treatment was generally well tolerated, with only one mild infusion reaction reported, indicating a favorable safety profile for infliximab in this patient population.

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.
