Activated PRP for Treatment of Androgenetic Alopecia

A clinical trial to assess the effects and safety of PRP activated with pulsed electrical fields (PEFA-PRP) compared with unactivated PRP when used to treat AGA.

The design of this small-scale, phase 1b/2a clinical trial is to demonstrate that pulsed electric field activation of autologous PRP results in a controlled release of platelet growth factors and other biologically active molecules that will have a benefit effect on the non-cycling hair follicles in the treated scalp compared to non-activated PRP. This single-center, auto-controlled study will compare the clinical benefit of PEFA-PRP versus non-activated PRP treatment of male patients with AGA.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male between 30 and 60 years of age, inclusive
  • A clinical diagnosis of AGA (stage II to V, according to the Hamilton-Norwood Scale)
  • Non-smokers in good general health, as determined by the Investigator
  • Willing and able to tolerate multiple injections and attend all study visits
  • Willing to maintain the same hair style as at the Screening Visit for the duration of the study
  • Willing to have blood drawn.

Exclusion criteria

  • Clinical diagnosis of alopecia areata or other non-AGA forms of alopecia
  • Scalp hair loss on the treatment area, due to disease, injury, or medical therapy
  • Current significant skin disease (e.g., psoriasis, atopic dermatitis, skin cancer, eczema, sun damage, seborrheic dermatitis) that might interfere with the study conduct or evaluations
  • History of surgical correction for hair loss such as transplantation
  • Previous exposure to Platelet-rich Plasma (PRP) for alopecia
  • Use of any products or devices purported to promote scalp hair growth (e.g., finasteride or minoxidil) within 30 days prior to the Screening Visit
  • Use of anti-androgenic therapies (e.g., spironolactone, flutamide, cyproterone acetate, cimetidine) within 30 days prior to the Screening Visit
  • No history of burning, flaking, itching, and stinging of the scalp
  • History of malignancy (except basal cell and squamous cell skin cancers) or undergoing chemotherapy or radiation treatments
  • A known history of autoimmune thyroid disease, any other thyroid disorder or other autoimmune disorders that in the opinion of the investigator may interfere with the study treatment
  • Significant tendency to develop keloids or hypertrophic scarring
  • A known history of significant physical or mental disease that the Investigator feels may impact the subject's participation
  • The use of aspirin or other NSAIDs (Nonsteroidal anti-inflammatory drugs) such as Nurofen, Voltaren, Diclofenac or Naproxen 7 days before beginning each of the treatments during the study
  • The use of Vitamin E supplements (other than in multivitamins) 14 days before beginning each of the treatments during the study
  • Current anticoagulant therapy (heparins; factor Xa inhibitors; direct agents such dabigatran, rivaroxaban, apixaban, edoxaban and betrixaban; warfarin/coumarins
  • Hereditary or acquired hematological/coagulation disorders such as: platelet dysfunction syndrome, critical thrombocytopenia, hypofibrinogenemia, impaired coagulation, drepanocytosis (sickle cell anemia)
  • Utilization of low-level lasers to scalp within 90 days prior to the Screening Visit
  • Platelet count of less than 150,000 platelets/µL as measured by automated complete blood cell count and differential at or around the time of treatment (within 3 days of injection)
  • Treatment with another investigational drug or other intervention within the previous 180 days
  • Current smoker or tobacco use within the previous 2 years

Treatment and study plan

Autologous Platelet-Rich Plasma

Biological

PRP created using a commercially available system will be used for treatment. PEFA-PRP will be created by subjecting PRP to a pulsed electrical field in a specially designed instrument developed by sponsor. Two 9 cm2 contralateral regions of interest (ROI) on the scalp will be treated with approximately 6mL of either PRP or PEFA-PRP by subcutaneous injection.

Primary outcomes

  1. Change in hair density and hair regrowth

    Time frame: Month 6 and Month 8

    The change in hair density (hair count and thickness) measured in the region of interest (ROI) at six months and eight months using automated image analysis with Trichovision/Fotofinder imaging software. The change will be compared to the following:

    • Baseline in the same ROI
    • An entire treatment area with diagnosed AGA on the scalp
    • The same region on the contralateral scalp
  2. Measurement of hair regrowth

    Time frame: Month 6 and Month 8

    The amount of hair regrowth measured in the region of interest (ROI) at six months and eight months using automated image analysis with Trichovision/Fotofinder imaging software. The change will be compared to the following:

    • Baseline in the same ROI
    • An entire treatment area with diagnosed AGA on the scalp
    • The same region on the contralateral scalp

Secondary outcomes

  1. Clinical progression of treatment as determined by principal investigator

    Time frame: Month 6 and Month 8

    Global photography evaluation by the PI using Norwood Hamilton scale.

  2. Clinical progression of treatment as determined by subject

    Time frame: Month 6 and Month 8

    Change in reported patient satisfaction outcome surveys.
