Not Applicable

Withdrawn

• Conditions: Androgenetic Alopecia
• Interventions: Device: Fractionated Thulium laser; Procedure: Autologous Platelet Rich Plasma Injection; Procedure: Autologous Platelet Rich Plasma Topical Application

• Registration Number: NCT05129254
• Lead Sponsor: Montefiore Medical Center

Brief Summary

The objective of this clinical study is to compare the safety and efficacy of a laser and topically applied platelet-rich plasma vs. platelet rich plasma injection in the treatment of male-pattern hair loss. Participating subjects will receive up to four (4) monthly treatments and will have a 12 month follow-up period.

Detailed Description

This is a single institution, open-label, baseline-controlled, prospective study evaluating the use of a non-ablative fractionated thulium laser and topical autologous platelet-rich plasma (PRP) vs. PRP injection for the treatment of male androgenetic alopecia (MAA). Given that this is a feasibility study, the investigators do provide formal sample size calculations. The findings of the study will inform that effect size associated with the treatment under study, which will inform the sample size (and power) calculations of a full, large-scale study. For this feasibility study, the investigators conservatively estimated the number of eligible patients that can reasonably enroll in the study time frame. Over the course of 1 year, the investigators typically see 50 patients with this condition annually. Of those, the investigators anticipate 25-50% would be eligible and agree to participate in the study. Given this, the investigators reasonably believe the enrollment will be 12 male subjects, ≥ 18 years of age at time of signed informed consent, of whom 6 will be randomized to receive laser + topical PRP and 6 to receive PRP injection. Follow-up visits are planned for months 7, 10, 13, and 16. Standardized photography, hair density measurement of the treated scalp areas will be recorded Pre and Post Treatment at each visit. Measurement outcomes will be compared to baseline. During the initial visit, subjects who meet the study's eligibility criteria will receive the first treatment after signing informed consent form.

Arm && Interventions

Group	Intervention	Description
Thulium laser (1927nm) and post-treatment topically administered platelet rich plasma (PRP)	Autologous Platelet Rich Plasma Topical Application	All participating subjects will serve as their own baseline control and will receive treatment of their androgenetic alopecia with LaseMD, a 1927nm Fractionated Thulium laser and post-treatment topically applied autologous platelet rich plasma at monthly intervals for a total of 4 treatment. The total duration of laser application, venipuncture, PRP preparation, and topical administration will take approximately 30 minutes. Post-treatment surveillance: The subject will be observed in the clinic under direct supervision of the treating physician for any post-treatment side-effects for up to 15 minutes.

The total duration of venipuncture, PRP preparation, and injection will take approximately 15 minutes. Post-treatment surveillance: The subject will be observed in the clinic under direct supervision of the treating physician for any post-treatment side-effects for up to 15 minutes.

Primary Outcome Measures

Name	Time	Method
Percentage of subjects with score of 2 or 3 on Clinician Global Aesthetic Improvement (CGAIS) scale at month 7 follow-up.	7 months	Clinician Global Aesthetic Improvement Scale (CGAIS) is a Likert scale, ranging from "greatly decreased (-3)" hair growth to "greatly increased (+3)" hair growth.; Greatly decreased (-3) Moderately decreased (-2) Slightly decreased (-1) No change (0) Slightly increased (+1) Moderately increased (+2) Greatly increased (+3); Based on a live assessment of the subject while referring to the subject's pre-treatment scalp photographs, the clinician will make an assessment of post-treatment hair growth.
Percentage of subjects with score of 2 or 3 on Subject Global Aesthetic Improvement at month 7 follow-up.	7 months	Subject Global Aesthetic Improvement Scale (SGAIS) is a Likert scale, ranging from "greatly decreased (-3)" hair growth to "greatly increased (+3)" hair growth.; Greatly decreased (-3) Moderately decreased (-2) Slightly decreased (-1) No change (0) Slightly increased (+1) Moderately increased (+2) Greatly increased (+3) Subjects will be given a hand mirror for self-assessment of post-treatment hair growth compared to subject's pre-treatment scalp photographs.

Secondary Outcome Measures

Name	Time	Method
Percentage of subjects with score of 2 or 3 on Patient Satisfaction Questionnaire at month 7 follow-up.	7 months	Patient Satisfaction Questionnaire will use Lickert scale, ranging from "greatly decreased (-3)" to "greatly increased (+3)".; Greatly decreased (-3) Moderately decreased (-2) Slightly decreased (-1) No change (0) Slightly increased (+1) Moderately increased (+2) Greatly increased (+3); The seven point Lickert scale will apply to following patient satisfaction questions: Please choose the option that better represents the change in how your hair looks OVERALL in the area treated? Please choose the option that better represents the change in your hair THICKNESS in the area treated? Please choose the option that better represents the change in your hair SHEDDING/LOSS in the area treated? Please choose the option that better represents the change in your hair DARKNESS in the area treated.
Reported pain score on Numeric Rating Scale for Pain for first 4 months during treatment	4 months	The Numeric Rating Scale for Pain is an 11-point scale scored from 0-10, with 0 = no pain, 5 = moderate pain, and 10 = worst possible pain. Subjects select a value that is most in line with the intensity of their pain experienced during and after treatment with Thulium Laser and topical platelet rich plasma or platelet rich plasma injection. The NRS pain questionnaire will be given to participants to complete for each treatment for the first 4 months of the study.
