Active clinical trials for "Alopecia Areata"

The goal of this clinical trial is to learn about the effectiveness and safety of platelet-rich plasma (PRP) and topical 5% minoxidil combination therapy compared with topical 5% minoxidil monotherapy in male androgenetic alopecia. The main questions it aims to answer are: Is there a difference in average change of hair density between groups that were given a combination of PRP injection and topical minoxidil compared to topical minoxidil as monotherapy? Is there a difference in average change of hair thickness between groups that were given a combination of PRP and topical minoxidil compared to topical minoxidil as monotherapy? Are there any differences in side effects between groups that were given combination of PRP and topical minoxidil compared to topical minoxidil as monotherapy?

This is a multi-center Phase 3 study to evaluate the safety and effectiveness of an investigational study drug (called Jaktinib) in adults (≥18 years and <65 years) who have 50% or greater scalp hair loss. The study is placebo-controlled, meaning that some patients entering the study will not receive active study drug but will receive tablets with no active ingredients (a placebo). It is double-blinded, meaning that the Sponsor, the study doctors, the staff, and the patients will not know whether a patient is on active study drug (or the dose) or placebo.

The purpose of this study is to evaluate the efficacy of Deucravacitinib versus placebo at Week 24 and safety and tolerability of Deucravacitinib versus placebo in adults with Alopecia Areata.

Participants who enroll in this study will undergo the platelet-rich plasma (PRP) study treatment. Participants will have a sample of blood collected and the platelets will be separated and then injected into half of the participants' scalp every 4 weeks for 12 weeks.

Introduction Alopecia areata (AA) is a complex inflammatory disease characterized by cellular infiltration of T- lymphocytes targeting hair follicles, disrupting the anagen phase, with spontaneous remission, recurrence, and exacerbation, making it very unpredictable and emotionally disturbing . It affects nearly 1-2% of the general population with a lifetime risk of 2%, The onset of AA might be at any age; however, most patients develop the disease before 40 years of age . Early-onset AA (a mean age of onset at 5-10 years) predominantly presents as a more severe subtype, such as alopecia universalis . Alopecia areata presents clinically as a non-scarring patchy hair loss primarily on the scalp, and/or other hairy areas and may progress to total scalp hair loss (alopecia totalis, AT ) or complete body hair loss (alopecia universalis, AU ) . Approximately 5- 10% of AA patients will progress into AT/AU . The course of AA varies greatly, the strongest predictors of a poor prognosis include AT, AU, or ophiasis pattern hair loss, as well as earlier age of onset . Severe and recurrent AA disturbs quality of life of patients and may also lead to depression, changed self-image,and interferes with social activities . Currently, the hypotheses for AA development mostly focus on the collapse of immune privilege properties of the hair follicles(HFs) and the nature of self-antigen presentation (follicular antigens) that result in the induction and subsequent attack of activated lymphocytes . Activation of the lymphocytes mainly CD8+NKG2D+induces release of severalTh1 cytokines; interleukin (IL)-1α , IL-1β , and tumor necrosis factor (TNF) alpha, capable of inhibiting (HF) growth with early termination of anagen . AA is a polygenic disorder in which several major genes dictate susceptibility to disease, up to 28% of patients report at least one affected family member, monozygotic twins have exhibited similar times of onset and patterns of hair loss. Genes loci for Human leucocyte antigens (HLA)DRB1* 1104 and DQB1* 03 are detected in patients with AA. The Janus kinases (JAKs) and signal transducer and activator of transcription (STAT); (JAK/STAT) pathway play an important role in inflammatory processes as they are involved in signaling for over 50 cytokines and growth factors. The JAK/STAT pathway transduces multiple extracellular signals involved in cell proliferation, differentiation, migration, and apoptosis . The JAK family is constituted by four types of cytoplasmic tyrosine kinases: JAK1, JAK2, JAK3, and TYK2 . STAT, of which there are seven different subtypes (STAT1, STAT2, STAT3, STAT4, STAT5a, STAT5b, and STAT6) (17), is the other fundamental component of the cascade . After being phosphorylated by JAK, STAT translocates to the nucleus to induce the transcription of specific genes. Alterations in the JAK/STAT pathway have been related to the pathophysiology of atopic dermatitis (AD), vitiligo, and AA.

The purpose of the study is to see if Clascoterone can help people with male pattern hair loss to recovery and see if the treatment is effective and safe and how well the drug is tolerated by subjects. Within this study, the Clascoterone solution will be compared to a placebo. The study has 2 parts: Part 1 will see if Clascoterone solution is effective and safe compared to a placebo when applied twice daily for up to 6 months. Part 2 will see the long-term safety and efficacy of the Clascoterone solution compared to placebo for additional 6 months in subjects defined as ''responders'' in Part 1. A responder is defined as someone who have responded to the study drug, based on research data. Part 1 of the study is double-blind, meaning that neither the subject nor the study doctor knows which treatment subject is receiving. Part 2 of the study is single-blind and only the study doctor doing the study knows which treatment subject is receiving. Part 1 of the study will start with baseline visit during which subjects will be randomly assigned (by chance) in ratio 2:1 to apply either Clascoterone or placebo solution to their balding areas of the scalp. Subjects will have 5 clinic visits and 2 follow-up phone calls during 6 months of Part 1 duration. Subjects identified as Part 1 responders at Month 6 visit will be again randomly assigned in ratio 2:1 to receive either study drug or placebo. Part 2 of the study will consist of 2 additional clinic visits and treatment will last for further 6 months. Each subject will have also an end of study visit one month after the study drug treatment has been completed or discontinued (it will be one month after end of Part 1 for not responder subjects). For those subjects who complete the whole study (Part 1 and Part 2), the total duration of the study will be about 14 months, with 12 months of treatment with a total of eight clinic visits and two phone calls. Subjects taking part in this study will have the medical tests or procedures described below. They will be asked about their previous medical history and current medications. A brief physical examination will be performed. Vital signs, weight and height will be measured. Electrocardiograms will be performed. Subject's scalp will be checked for any signs of irritation. Two different types of photos will be taken during this study: "global photos", i.e. general photos of the subject's scalp and "macro photos", i.e. close up photos of a region of the subject's scalp. Global photos will be taken to help the subject and the study doctor to assess whether there has been a change in subject's hair growth. Macro photos will be used to count the number of hairs in a region of the subject's scalp and measure other properties of the hair (hair width and hair darkness). Blood draws and urine sample collection for safety laboratory tests. Subject will be asked to complete, on site, the following two questionnaires: Cosmetic Evaluation - a couple of cosmetic questions on acceptability and how easy the study drug is to use. Male Androgenetic Alopecia Questionnaire - some questions about subject's hair assessment. Eligible subjects will be given a supply of the study drug and shown how to use and store it. The first study drug dose will be applied at the clinic under the supervision of the study staff. Subjects will be instructed to apply about 1.5 ml of study drug with a dropper to the balding areas of the scalp on the vertex and the temples twice daily, once in the morning and once in the evening. Subjects will be asked to bring back all used containers of study drug and all unused study drug to each study visit. Subjects will also be given a diary, shown what things have to be recorded on it and asked to bring back the completed diary to the study center at each visit.

The purpose of this study is to evaluate the efficacy of Finlândia hair lotion association in the treatment of androgenetic alopecia.
