Evaluation of Efficacy and Safety of Oral Minoxidil 1 mg in Female Androgenetic Alopecia

Recruiting now · Phase 3 · Has a placebo group

Conditions studied: Androgenetic Alopecia, Female Pattern Baldness

In brief

The goal of this clinical trial is to learn about oral minoxidil 1mg in the treatment of women with androgenetic alopecia, a type of hormone-imbalanced hair loss. The main questions to answer are to know about that minoxidil 1mg is as effective as minoxidil 2% topical solution (comparator product) and is more effective than placebo; and to ensure treatment with oral minoxidil is safe. Participants will be assigned randomly to receive one of the following treatment combinations: * the test product (oral minoxidil 1 mg, once/day) and the vehicle solution (vehicle means it looks like the comparator product, but it does not contain an active ingredient, 2 times/day), or * the placebo tablet (placebo means it looks like the test product, but it does not contain an active ingredient, once/day) and the comparator product (2% minoxidil solution, 2 times/day), or * the placebo tablet (once/day) and the vehicle solution (2 times/day). The clinical trial will take up to 36 weeks. During this time, patients will come to the clinical trial centre for 5 times for examinations and will be called by phone twice. At the visits, the following examinations will be performed: photos of the hair will be taken to determine hair density, assessment of changes in scalp hair growth, measurement of blood pressure, pulse, and body temperature, a physical examination, blood withdrawal to determine any abnormalities in the blood, urine sampling and analysis, performance of ECG, and evaluation of hypertrichosis (i.e., excessive hair growth over the body). Furthermore, patients will be asked daily whether they had experienced any side effects or took any new medications (or changed the dose of a known medication) or underwent any medical procedure. Also, women of childbearing potential must undergo pregnancy tests in blood and urine.

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Female patients aged 18 years or older, with general good health (i.e., with no history of cardiovascular disorders, or any other clinically significant disease).
• Diagnosed with FAGA, based on a discernible decrease in hair density (Sinclair Scale 2-4) in the centroparietal area of the scalp.
• Hair color of patient provides sufficient contrast with the scalp and as confirmed by TrichoLab Virtual Tattoo® technology at Screening/Visit 1.
• A personally signed and dated informed consent document indicating that the patient, has been informed of all pertinent aspects of the clinical trial.
• Negative serum pregnancy test at Visit 1/Screening and negative urine pregnancy test at Visit 2/Baseline for women of child-bearing potential (WOCBP).
• WOCBP must either be permanently sterile1 or agree to use a highly effective birth control method (failure rate ˂1% per year when used consistently and correctly) throughout the clinical trial and for at least 2 weeks after last administration of IPs.
• Gestagens with antiandrogen properties (e.g., cyproterone acetate, dienogest) are allowed if treatment is stable since the last 6 months prior to Visit 2/Baseline and if used as contraceptive and planned to be continued throughout the clinical trial duration.
• Patients willing to maintain the same hairstyle (color and hair regimen) throughout the clinical trial. Hair length must remain of sufficient length to not affect determination of hair density and patient should discuss with clinical trial personnel before changing from Visit 2/Baseline.
• Patient is willing to maintain the same depilatory habits and intervals regarding facial or body hair before each visit throughout duration of the clinical trial.
• Patient is willing and able to comply with scheduled visits, treatment plan, laboratory tests and other clinical trial procedures, including daily e diary recordings by the patient using an own electronic device (e.g., tablet, smartphone, personal computer) and an internet connection during the clinical trial.

You may not qualify if…

• Known hypersensitivity or known allergy to minoxidil or to any of the other components of the products.
• Pregnancy or pregnancy desire during the clinical trial.
• Breastfeeding/Nursing women.
• Any diagnosed treated or untreated hypertension (or blood pressure values >150 mmHg systolic / >95 mmHg diastolic) as determined at Visit 1/Screening, and/or history/signs of known cardiovascular diseases (including but not limited to cardiac ischemia, congestive heart failure, cardiac arrhythmia), and patients with pathologies or punctual situations that might either be caused by or increase the risk of cardiac disorders.
• Patients with any dermatological disorders of the scalp in the target region at Visit 1/Screening with the possibility of interfering with the application of the IPs or examination method, such as
• Active moderate or severe seborrheic dermatitis under chronic treatment, abrasion, actinic keratosis, or inflammatory disorders, or
• any local infection of the skin/subcutaneous tissues of the head within the previous 3 months, or
• any documented history of active atopic dermatitis or psoriasis in the scalp within the previous 6 months.
• any other types of alopecia (e.g., alopecia areata or scarring alopecia) at any time point or diffuse telogen effluvium, trichotillomania, or other pathological hair loss conditions/diseases other than AGA in the last 3 months at the discretion of the investigator).
• Patients who had hair transplant surgery at any time.
• Patients who had hair weaving, or any other hair extension methods within the last 6 months prior to Visit 2/Baseline.
• Clinically significant abnormal laboratory values or ECG findings (if applicable) at Visit 1/Screening indicative of physical illness, according to investigator assessment.
• Both creatinine and eGFR above upper limit of normal at Visit 1/Screening.
• Relevant history of renal, hepatic, gastrointestinal, cardiovascular, respiratory, skin, hematological, endocrine, or neurological diseases that in the opinion of the investigator may interfere with the aim of the clinical trial.
• Patient has used any of the following topical preparations or procedures on the scalp:
• Topical scalp treatments for hair growth, including minoxidil within the last 6 months prior to Visit 2/Baseline; or hormone therapy, antiandrogens, or other agents that are known to affect hair growth within 12 weeks prior to Visit 2/Baseline.
• Topical scalp treatments that might have had ancillary effect on hair growth including, but not limited to, corticosteroids, pimecrolimus, and tacrolimus within the last 4 weeks prior to Visit 2/Baseline.
