What side effects are associated with this type of intervention?

Common treatments for vitiligo include topical corticosteroids, ultraviolet radiation combined with topical preparations, and topical immunomodulators like pimecrolimus. Side effects of these treatments can include skin irritation, burning sensation, erythema, and an increased risk of skin cancer with prolonged UV exposure. For treatments similar to AMG 714, such as other monoclonal antibodies, side effects may include injection site reactions, increased risk of infections, and potential hypersensitivity reactions. Long-term safety data for these newer treatments are still lacking.

What prior FDA approvals exist?

As of the latest information, there are no FDA-approved drugs specifically for the treatment of vitiligo. Various treatments, including topical corticosteroids, ultraviolet light therapy, and immunomodulatory agents, have been explored, but none have received FDA approval. AMG 714, an anti-IL-15 monoclonal antibody, is currently being studied for its efficacy in treating vitiligo, but it has not yet been approved.

What other types of research exist?

Promising novel alternatives to AMG 714 for vitiligo patients include Janus kinase inhibitors such as tofacitinib, ruxolitinib, and baricitinib. These therapies are currently being studied for their efficacy in treating vitiligo by targeting immune pathways involved in the disease.

Summary

This trial is testing AMG 714, a medication for adults with vitiligo. It works by blocking a protein that affects the immune system, potentially helping the skin regain its color.

Who is the study for?

Adults aged 18-75 with stable or active vitiligo, as diagnosed by a dermatologist. Participants must have had no new vitiligo lesions in the past 3 months for stable cases, and willingness to stop other treatments and undergo nbUVB phototherapy. Not eligible if using certain medications, have skin conditions that could affect assessments, history of cancer (with exceptions), infections like HIV/HBV/HCV/tuberculosis, segmental vitiligo, or uncontrolled thyroid issues.

What is being tested?

The trial is testing AMG 714's effectiveness on adults with vitiligo compared to a placebo while also receiving narrow band ultraviolet B (nbUVB) phototherapy. The goal is to see if AMG 714 can improve the skin condition better than no treatment alongside light therapy.

What are the potential side effects?

While specific side effects are not listed here, potential risks may include reactions related to immune system modulation such as inflammation or infection risk due to AMG 714 and typical side effects from nbUVB phototherapy like redness or irritation.

Other Research

The most common treatments for vitiligo include topical corticosteroids, ultraviolet radiation, and narrowband UVB phototherapy. Topical corticosteroids work by reducing inflammation and modulating the immune response, which can help to halt the progression of depigmentation. Ultraviolet radiation, particularly narrowband UVB phototherapy, stimulates melanocyte activity and promotes repigmentation by inducing local immunosuppression and increasing melanocyte proliferation. These treatments are crucial for vitiligo patients as they address the underlying immune-mediated destruction of melanocytes, offering a chance for repigmentation and improved skin appearance. AMG 714, an anti-IL-15 monoclonal antibody, targets the IL-15 pathway, which is involved in the immune response. By inhibiting IL-15, AMG 714 may reduce the autoimmune attack on melanocytes, similar to how other treatments aim to modulate the immune system to preserve or restore pigmentation.
