Keloid Scars
The “tough problem”
► Progressive growth that extends past original scar
● Invades and destroys normal skin and tissue
► Cause of keloid formation still not understood; several theories
● Alteration in Dermal “Environment”
● Collagen Turnover
● Genetic Immune Dysfunction
● Viral Cause or Trigger
Little new in treatment of keloids over past 20 years;
standard treatment may involve:
standard treatment may involve:
► Steroid injection
► Radiation
► Pressure
► 5-fluorouracil

Multiple Signals of Efficacy
7-Month Interim Analysis of Selected Metrics Reveals
Multiple Signals of Efficacy
► Monthly statistical tests performed: Months 3-7
(7 outcomes x 5 months x 2 comparisons = 70 tests)
(7 outcomes x 5 months x 2 comparisons = 70 tests)
● 8 tests yielded statistically significant or near significant results
● 7 of these 8 favored AZX100
Slightly more often at 3.0 mg than 10.0 mg
Most effects earlier than Month 7
Examples: Scar Total Volume @ Month 3 (p = 0.047);
Scar Length @ Month 5 (p = 0.034)

Clinical & Commercial Development?
Answer:
► Capstone believes the AZX100
development program in
dermal scarring should be continued
development program in
dermal scarring should be continued
To this end…
► Capstone is pursuing a pharma or biotech collaboration to
fund development
fund development
► Internal planning & development programs continue
► Clinical Pathway Indicated
● Initiate Phase 2 dose / administration optimization studies in both
keloid and normal scars prior to moving to Phase 3 registration trials
