A phase 2a randomized vehicle-controlled multi-center study of the safety and efficacy of delgocitinib in subjects with moderate-to-severe alopecia areata

Daniela Mikhaylov et al.

Summary: This study evaluated the efficacy and safety of topical delgocitinib in moderate-to-severe alopecia areata through a double-blind, randomized, vehicle-controlled clinical trial. The results showed that this topical medication was not effective in treating moderate-to-severe alopecia areata, possibly due to its inability to penetrate deeply into the scalp dermis.

Oral tofacitinib for the treatment of alopecia areata in pediatric patients

Jon Kibbie et al.

Summary: Oral tofacitinib was clinically effective in the majority of patients and well tolerated in the treatment of pediatric patients with AA at the University of Colorado Hospital Dermatology Clinic. 72.7% of patients experienced hair regrowth with oral tofacitinib, while 27.3% experienced minimal to no hair regrowth. No serious adverse events were recorded during the observed treatment period.

Evaluating the Therapeutic Potential of Ritlecitinib for the Treatment of Alopecia Areata

Hassiel Aurelio Ramirez-Marin et al.

Summary: Alopecia areata (AA) is a common autoimmune condition causing patchy hair loss, and there is currently no FDA-approved treatment specifically for AA. Ritlecitinib, a selective JAK3/TEC kinase inhibitor, has shown promising results in promoting hair regrowth and is being investigated for the treatment of other conditions. It offers advantages over other JAK inhibitors, with fewer side effects. Further research is needed to explore its long-term effects.

Summary: This study assessed the safety and efficacy of CTP-543 in patients with chronic, moderate-to-severe AA. The results showed a significant reduction in the severity of AA in patients treated with CTP-543. However, further studies are needed to confirm its safety and efficacy due to the small sample size.

Baricitinib in Alopecia Areata

Andrew Messenger et al.

Summary: For many individuals, alopecia areata is a temporary issue with hair loss patches recovering spontaneously within a few months. However, for a significant portion of patients, this condition can persist long-term and progress to complete baldness, with limited chances of recovery. Severe cases of alopecia often do not respond to medical treatments, leaving patients to struggle with the challenges it presents.

A Comprehensive Literature Review of JAK Inhibitors in Treatment of Alopecia Areata

Kerry-Ann L. Dillon

Summary: Alopecia areata is a chronic and complex immune-mediated form of nonscarring alopecia with no specific approved treatment. However, the emerging use of janus kinase (JAK) inhibitors as targeted therapy in the management of Alopecia areata has shown promising results.

A. Sterkens et al.

Summary: Patients with alopecia areata may experience hair loss in various regions of the body, and the exact pathology is still unknown. Available treatment options have limited effectiveness and potential side effects, with high relapse rates. Prognosis is uncertain and influenced by subtype and associated characteristics.

Ritlecitinib: an investigational drug for the treatment of moderate to severe alopecia areata

Samantha Eisman et al.

Summary: Alopecia areata is an inflammatory and autoimmune form of hair loss with limited therapeutic options. The novel oral JAK3-selective inhibitor Ritlecitinib shows promise as a potential therapy, with a unique mode of action and potentially superior safety profile over other JAK inhibitors. If approved, Ritlecitinib may become widely prescribed for severe AA patients in the future, and may also have potential applications in other hair loss disorders.

Targeting Sphingosine-1-Phosphate Signaling in Immune-Mediated Diseases: Beyond Multiple Sclerosis

Tamara Perez-Jeldres et al.

Summary: Sphingosine-1-phosphate (S1P) acts through 5 G-protein-coupled receptors to regulate lymphocyte trafficking and is involved in the pathogenesis of immune-mediated diseases. Modulators of S1P receptors have shown promise in treating diseases like multiple sclerosis and are being evaluated for other immune-related conditions.

Gut microbiota characterization in Chinese patients with alopecia areata

Jinghao Lu et al.

Summary: The study found that the gut microbial composition of patients with alopecia areata was distinct from that of healthy controls, despite no significant differences in alpha-diversity. Three AA-associated microbial markers were identified using a random forest model, which may potentially be used for earlier diagnosis and as therapeutic targets.

Resident Memory T Cells in Autoimmune Skin Diseases

Grace E. Ryan et al.

Summary: Tissue resident memory T cells (TRM) play a crucial role in the immune system by providing immediate and specific responses against pathogens re-infecting peripheral tissues. However, they have also been found to contribute to autoimmune diseases, where self-antigens continuously activate self-reactive TRM T cells, leading to destructive outcomes. This article focuses on how TRMs mediate disease in autoimmune skin conditions, such as vitiligo, psoriasis, cutaneous lupus erythematosus, alopecia areata, and frontal fibrosing alopecia.
