Safety and Tolerability of Hair Stimulating Complex (HSC) in Female Pattern Hair Loss

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.

Inclusion Criteria:

- Female, 40-70 years of age.

- 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.

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.

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
exclusion criteria, and that a daily dose of 81 - 325mg aspirin is also permitted).

- (Auto-) Immunological disorders such as HIV positive, alopecia areata, and systemic
lupus erythematosus.

participation in any clinical trial during the duration of their participation in this
study.

months.

- Damaged skin in or around test sites (including sunburn, uneven skin tones, tattoos,
scars or other disfiguration of the test site).

- Use of any over-the-counter or prescription hair/scalp treatments for less than 6
months from date subject would start study, including finasteride or minoxidil.

- Discontinuation of the use of an over-the-counter or prescription hair/scalp
treatments within the last 6 months

- Use of laser or light device for the scalp for purposes of hair growth within the last
6 months or any plans to use these devices during the duration of the study.

- History of hair transplantation surgery during the last 6 months.

- Currently using hair system or wig and/or unwilling to refrain from use throughout the
duration of the study.

- History of malignancy, other than non-melanoma skin cancer. Any condition for which
the Investigator determines that the subject could be placed under undue hazard.
