Study summary

This double-blind placebo-controlled study will assess the tolerability, feasibility, and pharmacodynamics of intradermal Hair Stimulating Complex (HSC) in up to 18 of 27 women with Ludwig 1 or 2 classification or the Savin Frontal classification of hair loss. Safety measures include vital signs, dermatological examination of the scalp, pre- and post-dose blood and urine collection, as well as Investigator Global Assessments and subject self assessments throughout the 22-week study.

Read the detailed description

The study is a double-blind, placebo-controlled, randomized single site trial. The study is to be conducted in La Jolla, CA and is primarily designed to evaluate safety in the clinical application of injected HSC by assessing the tolerability of HSC, as well as the volume that can be delivered safely in the intradermal region of the scalp using a syringe with 31-gauge 1.75 mm length needle. The main study (18 weeks) involves the two treatment time points, collection of lab samples (blood/urine) for screening, and before and after the two treatment time points. Six of the seven total visits (including screening) in the study are conducted in the first 18 weeks. The final visit is for investigator monitoring, global photographs and final lab collection 30 days after the 18-week evaluation point. A 2 year follow up questionnaire will be sent to the patient to collect additional safety information. Additional dermatological exam of the scalp, as well as Subject and Investigator Assessments will also be assessed. The secondary goal of the study will be to explore whether an efficacy signal of the change in hair growth can be detected using an independent panel of physician's comparing global photographs taken at baseline to week 18 (and baseline to week 22), for changes.

Ran from Jul 2018 to primary completion in Jan 2019, 6 months.

Of 37 phase 1 interventional studies under Alopecia, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 25. This study's 6 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 21, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
