What is the purpose of this trial?

This trial aims to test Daxdilimab, a new treatment for individuals with moderate to severe Alopecia Areata (AA), a condition causing significant hair loss on the scalp. Researchers seek to evaluate the effectiveness, safety, and tolerability of Daxdilimab. Participants should have lost between 50% and 95% of their scalp hair due to AA, with the current episode lasting more than 3 months but less than 7 years. The study seeks individuals who haven't experienced significant hair regrowth recently and are willing to maintain their current hairstyle and color during the trial. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial requires that you stop using certain medications that might affect hair regrowth, such as steroids, minoxidil, and some topical treatments, at least 4 weeks before starting the trial. Other medications like biologics or immunosuppressants need to be stopped 8 weeks or more before the trial, depending on the specific drug.

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

Research indicates that specific safety information for Daxdilimab in people with alopecia areata is not yet available. However, Daxdilimab is in a Phase 2 trial, which means smaller groups have already tested it for safety. Treatments in this phase typically demonstrate some level of safety and are generally well-tolerated.

Daxdilimab targets certain immune cells. Similar treatments have been well-tolerated in other conditions. While this does not guarantee safety, it suggests that Daxdilimab might be safe for people. Researchers will closely monitor trial participants to ensure their safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike standard treatments for alopecia areata, which typically involve corticosteroids or topical immunotherapy, Daxdilimab is unique because it works by targeting the immune system differently. This treatment is a monoclonal antibody that specifically inhibits a protein involved in the inflammatory process, potentially reducing hair loss by directly addressing the immune response. Researchers are excited about Daxdilimab because it offers a novel approach that might provide more targeted and effective results, potentially with fewer side effects compared to current options.

What evidence suggests that Daxdilimab might be an effective treatment for alopecia areata?

Research has shown that Daxdilimab, the treatment being tested in this trial for alopecia areata (AA), works by adjusting the immune system. This method resembles other successful treatments, such as Dupilumab, which has helped some patients fully regrow their hair over time. Early results suggest that new drugs like Daxdilimab could be promising for treating severe AA. Although specific data on Daxdilimab's effectiveness is still being gathered, its mechanism offers hope for reducing hair loss by addressing the immune system's role. ^{2 3 6 7 8}

Exclusion Criteria

You have tested positive for hepatitis B or C.

Individuals involved in the conduct of the trial, their employees, or immediate family members

You have ongoing skin conditions or signs of inflammation on your skin.

Published Research Related to This Trial

JAK inhibitors represent a significant advancement in the treatment of moderate-to-severe alopecia areata (AA), a condition that previously had limited treatment options.

Phase 3 clinical trial data supports the efficacy of JAK inhibitors in treating AA, highlighting the importance of understanding the differences among various JAK inhibitors for optimal patient selection and safety considerations.

Janus kinase inhibitors for alopecia areata. King, BA., Craiglow, BG.[2023]

Dupilumab, an immune-modulating drug, has shown long-term efficacy in treating alopecia areata in a 16-year-old patient, leading to complete hair regrowth and significant improvement in atopic dermatitis over three years.

This case suggests that dupilumab's mechanism of action, which involves blocking Th2 immune response signaling, may have broader applications in treating autoimmune conditions, although further research is needed to fully understand its effects on alopecia areata.

Long-Term Efficacy of Dupilumab in Alopecia Areata. Kulkarni, M., Rohan, CA., Travers, JB., et al.[2022]

A systematic review of 28 studies involving 1719 patients found that JAK-inhibitors for alopecia areata are generally well-tolerated, with most adverse events being mild and a low withdrawal rate due to side effects (1.6% compared to 2.2% for placebo).

Common adverse events included laboratory abnormalities (40.1%), respiratory issues (20.8%), and skin reactions (17.2%), but no fatal outcomes were reported, indicating a favorable safety profile for these treatments.

Baricitinib, an oral JAK inhibitor, is the first approved treatment for adults with severe alopecia areata (AA) and has shown consistent benefits in hair regrowth compared to placebo in multiple randomized controlled trials.

The review highlighted that while baricitinib has robust evidence supporting its efficacy, many other treatments for moderate-to-severe AA lack thorough evaluation in clinical trials, leading to inconsistent data on their effectiveness.

Tofacitinib demonstrated a high effectiveness and acceptable safety profile in treating alopecia areata, with a complete response rate of 33.8% after 24 weeks in a cohort of 80 patients.

The study, which included 126 patients treated over a median duration of 23 weeks, showed a good drug retention rate, with 90% of patients remaining on the medication after 12 weeks, indicating its potential for long-term use.
