Androgenetic Alopecia (AGA)

This study is designed to evaluate the safety, efficacy, tolerability, and pharmacokinetics (PK) of OLX72021 in medically healthy men with mild to moderate androgenetic alopecia.

This is a first-in-human study of ABS-201, a new investigational medicine, in healthy adult men and women. Its main purpose is to find out whether ABS-201 is safe and well tolerated, as well as to understand how the body processes it and how it affects related biological markers. ABS-201 is being developed as a possible treatment for androgenetic alopecia (male- and female-pattern hair loss); its effect on hair growth has not yet been established. The study has two parts: in the single ascending dose (SAD) part, healthy adults receive one intravenous dose of ABS-201 or placebo; and in the multiple ascending dose (MAD) part, participants (including men with androgenetic alopecia) receive several subcutaneous doses of ABS-201 or placebo. The MAD part also evaluates the effect of ABS-201 on hair growth. The main questions it aims to answer are: What medical problems, if any, do participants experience when taking a single dose or many doses of ABS-201? How does the medication, ABS-201, compare to placebo (a look alike substance that does not contain any medication). Participants who qualify for the trial will receive either ABS-201 or a placebo, and visit the study clinic for scheduled checkups and tests for approximately 12 months in the single ascending dose (SAD) part and approximately 18 months in the multiple ascending dose (MAD) part. In the MAD part, participants receive repeated subcutaneous doses.

The goal of this clinical trial is to learn if local scalp injection of human umbilical cord mesenchymal stem cell-derived exosomes (hUCMSC-Exos) can treat androgenetic alopecia (AGA) in male patients with AGA. The main question it aims to answer is: Does hUCMSC-Exos injection improve hair regrowth compared with placebo? Researchers will compare hUCMSC-Exos injection to placebo injection to see if hUCMSC-Exos leads to superior efficacy in hair follicle regeneration, as measured by changes in hair density, hair thickness, and patient-reported outcomes. Participants will: Receive randomized, double-blinded local scalp injections of either hUCMSC-Exos or placebo Attend scheduled follow-up visits for hair assessment and safety monitoring Undergo photography, trichoscopy, and complete quality-of-life or psychosocial burden questionnaires as applicable

This study utilizes a multi-omics approach to systematically characterize the cellular heterogeneity and spatial architecture of the hair follicle microenvironment in patients with androgenetic alopecia (AGA). Our primary aim is to elucidate the key mechanisms driving hair follicle stem cell (HFSC) exhaustion and to identify potential therapeutic targets. Investigators will collect six groups of scalp tissue samples, which include healthy controls and AGA patients (stratified into younger and older cohorts). By integrating spatial transcriptomics, single - cell sequencing data, investigators will map aberrant cell subpopulations and their complex interaction networks. Furthermore, the identified core targets will be functionally validated using patient-derived organoids and animal models. Expected outcomes include the identification of 3-5 critical cell subpopulations and the discovery of 8-10 disease-associated targets. Additionally, investigators will establish an integrated clinical-omics-validation database, providing a robust theoretical foundation for the precision diagnosis and treatment of AGA.

This study aims to evaluate the effectiveness and tolerability of a peptide-based hair serum compared with topical minoxidil in patients with androgenetic alopecia. Participants will be randomly assigned, in a double-blind manner, to receive either the peptide hair serum or topical minoxidil. The primary objective is to assess improvement in hair growth over the study period, including changes in hair density and hair thickness. Secondary outcomes will include safety and tolerability assessments. The findings of this study may provide evidence supporting an alternative treatment option for patients with androgenetic alopecia.

This study is a Phase 3 clinical trial designed to evaluate the efficacy and safety of N1087 compared with placebo in adult men with androgenetic alopecia (male pattern hair loss). The study will include male participants aged 18 to 60 years who have a clinical diagnosis of androgenetic alopecia classified as stages 3V, 4, or 5 on the Norwood-Hamilton scale. Participants will be randomly assigned, in a 2:1 ratio, to receive either N1087 or placebo. Neither the participants nor the study team will know which treatment each participant receives. The study treatment will be taken orally once daily for a total of 24 weeks. During the first 8 weeks, the dose will be gradually increased (titration period) up to a maximum tolerated dose, not exceeding 5 mg. Participants will then continue treatment at the maximum tolerated dose for the remaining 16 weeks. The main purpose of the study is to assess whether oral minoxidil improves hair growth. The primary outcome measure is the change from baseline in the density of non-vellus hairs in a defined target area of the scalp (vertex) after 24 weeks of treatment, measured using digital phototrichogram analysis. Secondary objectives include evaluating changes in hair density at earlier time points, hair thickness, the proportion of terminal hairs, clinical improvement assessed by the investigator, quality of life related to hair loss, and participant satisfaction with treatment. The safety and tolerability of oral minoxidil will also be evaluated by monitoring adverse events, vital signs, and events of special interest throughout the study. An independent Data and Safety Monitoring Committee will oversee participant safety during the trial. This is a multicenter study conducted in Brazil, with approximately 372 participants expected to be enrolled.

Androgenetic alopecia is a condition that bothers a lot of people. The disadvantage of the FDA approved topical minoxidil is that the patient needs to be compliant every day for extended periods of time. This is the main reason why this study is being conducted, to see if a single nanofat injection is superior to applying either topical Minoxidil or PRP

The primary objective of the study is to assess the safety and efficacy of DA-001 as a treatment for Hair Shedding Reduction and Hair Re-Growth

This is a single-center, randomized, double-blind, placebo-controlled clinical trial designed to evaluate whether topical application of Lactobacillus reuteri can safely and effectively treat androgenetic alopecia. The study is based on the concept that balancing the scalp's microbial community may support hair follicle function. Participants will be randomly assigned to one of four groups receiving either active probiotic solution, inactivated probiotic solution (control for non-viable bacterial effects), a saline placebo, or the standard treatment 5% minoxidil solution for 12 months. Neither participants nor assessing clinicians will know the assigned treatment. The main goal is to measure improvement in hair count per square centimeter after one year. Additional measures include changes in hair thickness and quality. This research seeks to provide high-quality scientific evidence on a new microbiome-targeting approach, offering future patients and healthcare providers insights into a potential alternative or complementary treatment strategy for hair loss.

Androgenetic alopecia (AGA) is a common cause of hair loss worldwide. It mainly affects the frontal and parietal regions of the scalp in up to 70 % of men and 40 % of women and has a significant negative psychological and emotional impact on those affected. Various therapies are currently approved for the treatment of AGA in men and women, including topical minoxidil, topical or systemic finasteride, platelet-rich plasma and hair transplantation. In addition to these pharmacological and surgical interventions, laser therapies including thulium laser with growth factors have gained popularity. Despite the clinical use of the thulium laser with growth factors in combination with LED phototherapy, there are only a few studies to date that have adequately investigated the objective and patient-side benefits of this therapy.

In order to successfully treat androgenetic alopecia (AGA), this study compares the efficacy of low-dose oral minoxidil dosages of 0.25 mg and 1 mg. It addresses a critical gap in current research, as few studies have examined the relationship between low dosage and outcomes like hair diameter, density, patient satisfaction, and adverse effects, including hypertrichosis. Previous research suggests that low dose of oral minoxidil is a safe and well-tolerated option for hair loss, but the optimal dose for maximizing benefits while minimizing side effects remains unclear. This study aims to determine which dose offers the best balance of efficacy and safety for AGA patients.

The goal of this clinical trial is to learn if dihydroartemisinin (DHA) works to treat Androgenetic Alopecia (AGA) in female adults. The main question it aims to answer is: • Does DHA increase terminal hair follicles in the vertex area. Researchers will compare oral DHA plus topical minoxidil to topical minoxidil alone in female patients with AGA to see if DHA works to alleviate AGA. Participants will: * Receive oral DHA every day plus topical minoxidil or use topical minoxidil alone for 6 months. * Visit the clinic once every month for checkups and tests.
