Brief 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.

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.

Interventions

Patients will receive 2 mL of HSC separated by 6 weeks (total of 4 mL of HSC)

Inclusion criteria

* Female, 40-70 years of age. * A healthy scalp with no cutaneous disorder. * Good general health. * Must fulfill the Ludwig I or II classification or Savin classification of frontal hair loss (see Appendix 1). * Willing and able to comply with scheduled visits (6 visits in 22 weeks). * Willing to maintain the same hair style and color during the study period. * Subjects not already using any over-the-counter or prescription hair/scalp treatments, must be willing to refrain from starting use of any new hair/scalp products other than the provided study product for the duration of the study. * Willingness to have blood and urine samples taken before and after each of the two treatments to evaluate overall systemic effect and also at Weeks 18 and 22. Also willing to give additional serum samples at each collection for long-term storage and immunogenicity testing by Histogen to components in HSC. * Be able to speak and read English to the standard required to provide written informed consent and to cooperate with the study staff. * Female subjects will be either of non-childbearing potential defined as: 1. Having no uterus 2. No menses for at least 12 months. Or; (WOCBP) women of childbearing potential must agree to use an effective method of birth control during the course of the study, such as: <!-- --> 1. Oral contraceptive pill, injection, implant, patch, vaginal ring, intrauterine device 2. Intrauterine coil 3. Bilateral tubal ligation 4. Barrier method used with an additional form of contraception (e.g., sponge, spermicide or condom) 5. Abstinence (If practicing abstinence must agree to use barrier method described above (4) if becomes sexually active). 6. Vasectomized partner (Must agree to use barrier method described above (4) if becomes sexually active with non-vasectomized). \-

Exclusion criteria

* Known sensitivity to any of the test material ingredients. * History of keloid formation or hyperpigmentation. * Pregnant, planning pregnancy or breastfeeding during the course of the study. * A history of any acute or chronic illness that in the opinion of the investigators might confound the results of the study including some drugs or medications. * Active skin diseases (e.g. Eczema, seborrheic dermatitis, psoriasis, skin cancer, sun damaged skin with actinic keratosis on scalp, excessive number and size of seborrheic keratosis, etc.). * Routine high dosage use of anti-inflammatory medications (aspirin, ibuprofen, corticosteroids), immunosuppressive drugs or antihistamine medications (Note that steroid nasal spray / drops and/or topical steroids administered to the eye(s) are not
