Activated PRP for Treatment of Androgenetic Alopecia

Phase 1

Completed

• Conditions: Androgenetic Alopecia
• Interventions: Biological: Autologous platelet-rich plasma

• Registration Number: NCT05348343
• Lead Sponsor: Santiste Medical Inc.

Brief Summary

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.

Exclusion Criteria

1. Clinical diagnosis of alopecia areata or other non-AGA forms of alopecia
2. Scalp hair loss on the treatment area, due to disease, injury, or medical therapy
3. 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
4. History of surgical correction for hair loss such as transplantation
5. Previous exposure to Platelet-rich Plasma (PRP) for alopecia
6. 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

8. No history of burning, flaking, itching, and stinging of the scalp
9. History of malignancy (except basal cell and squamous cell skin cancers) or undergoing chemotherapy or radiation treatments
10. 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
11. Significant tendency to develop keloids or hypertrophic scarring
12. A known history of significant physical or mental disease that the Investigator feels may impact the subject's participation
13. 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
14. The use of Vitamin E supplements (other than in multivitamins) 14 days before beginning each of the treatments during the study

16. Hereditary or acquired hematological/coagulation disorders such as: platelet dysfunction syndrome, critical thrombocytopenia, hypofibrinogenemia, impaired coagulation, drepanocytosis (sickle cell anemia)
17. Utilization of low-level lasers to scalp within 90 days prior to the Screening Visit
18. 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)
19. Treatment with another investigational drug or other intervention within the previous 180 days
20. Current smoker or tobacco use within the previous 2 years

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Autocontrolled Arm	Autologous platelet-rich plasma	The subject will be treated with both the experimental treatment and the active comparator.

Primary Outcome Measures

Name	Time	Method
Change in hair density and hair regrowth	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: 1. Baseline in the same ROI; 2. An entire treatment area with diagnosed AGA on the scalp; 3. The same region on the contralateral scalp
Measurement of hair regrowth	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: 1. Baseline in the same ROI; 2. An entire treatment area with diagnosed AGA on the scalp; 3. The same region on the contralateral scalp

Secondary Outcome Measures

Name	Time	Method
Clinical progression of treatment as determined by principal investigator	Month 6 and Month 8	Global photography evaluation by the PI using Norwood Hamilton scale.
Clinical progression of treatment as determined by subject	Month 6 and Month 8	Change in reported patient satisfaction outcome surveys.
