About

This study tests whether XVIE, an investigational injectable product made from processed human amniotic fluid, is safe and may help regrow hair in adults with androgenetic alopecia (common pattern hair loss). XVIE contains growth factors and extracellular vesicles that may stimulate hair follicle activity. Thirty participants will be randomly assigned to receive either XVIE or a saline placebo injected into the scalp in two treatment sessions, 90 days apart. Neither participants nor study staff will know which treatment is being given. Participants will be followed for 6 months. The main goal is to evaluate safety. A secondary goal is to assess whether hair count, density, or coverage improves.

Full description

This Phase I/II randomized, double-blind, placebo-controlled trial evaluates the safety and preliminary efficacy of XVIE (decellularized allogeneic human amniotic fluid) administered via intradermal scalp injection in adults with androgenetic alopecia (AGA).

XVIE is manufactured by Nova Vita Laboratories, LLC under cGMP-aligned conditions. It contains naturally occurring soluble proteins, extracellular vesicles (nanoparticles 50-200 nm), and hyaluronic acid derived from full-term human amniotic fluid. Cellular components are removed by centrifugation and sterile filtration. Each lot is released against a 7-parameter specification panel including nanoparticle concentration, size, total protein, sterility, endotoxin, mycoplasma, and appearance.

Thirty adults (ages 18-70) with AGA will be randomized 1:1 to XVIE or placebo (0.9% saline). Both are supplied in identical 2.0 mL vials. Treatment is administered intradermally across 20 scalp injection sites (0.1 mL per site, 4-5 mm depth, 30-gauge needle) at Day 0 and Day 90. Final assessment occurs at Day 180 with no treatment administered.

Safety assessments include incidence, severity, and relatedness of treatment-emergent adverse events (TE-AEs) and serious adverse events (TE-SAEs), graded per CTCAE v5.0. Adverse events of special interest include scalp-specific events such as new-onset alopecia in previously unaffected areas, a decrease of 15% or greater in Total Area Hair Count within the injection zone, and scarring alopecia not consistent with natural AGA progression.

Efficacy assessments include Total Area Hair Count and hair density measured by Canfield HairMetrix imaging, global scalp coverage by SoCAI Global HairMap, Investigator and Subject Global Assessments (7-point scale), and quality of life via the Dermatology Life Quality Index (DLQI).

Male subjects must be Norwood-Hamilton Stage III-IVa; female subjects must be Ludwig Stage I-II. The study is conducted at two U.S. clinical sites: Advanced Dermatology and Cosmetic Surgery in Orlando, FL and Kindred Hair & Skin Center in Marriottsville, MD.

An independent Data Safety Monitoring Board (DSMB) will oversee participant safety throughout the trial. Enrollment will not begin until the DSMB is fully constituted and the DSMB Charter has been executed.
