Dermal Scarring: Range of Indications
Keloid Scars
 Overgrowth of dense fibrous
 tissue
 Extend beyond borders of
 original wound
 Do not regress
 spontaneously
 Tend to recur after excision
Hypertrophic Scars
 Red, itching, raised fibrous lesions
 Typically do not expand beyond
 boundaries of initial injury
 May undergo partial spontaneous
 resolution
 Common after thermal and other
 injuries that involve deep dermis
Normal Scars
 Various types:
  Flat, pale
  Sunken
  Red, dark, raised
  Result from surgery, burns
  acne

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:
           ►  Steroid injection
           ►  Radiation
           ►  Pressure
           ►  5-fluorouracil

AZX100 Phase 2a Clinical Trials - Keloid Scars
 Two Studies:
         ►  OL-ASCAR-04: 3.0, 10.0 mg per linear cm or placebo
         ►  OL-ASCAR-05: 0.3, 1.0 mg per linear cm or placebo

         ►  Reduction or prevention of recurrence following
           keloid scar excision
 Study Design:
         ►  Placebo-controlled; n = 59 in each study (118 dosed)
         ►  Two Intradermal injections
                   ●  21 ± 2 days following excision
                   ●  42 ± 2 days following excision

Summary
OL-ASCAR-04 & -05 Primary Efficacy Endpoints
     (POSAS @ Single Month 12 Time Point) Not Met
OL-ASCAR-05 Secondary Endpoints Reveal
     Multiple Signals of Efficacy Before Month 12
         ►  Consistent pattern favoring AZX100 treatment
           (1.0 mg per cm) across multiple outcomes &
           time points
         ►  With small sample size (n=19),
           signals not statistically significant
         ►  Serves as basis for next study design

AZX100 Phase 2a Clinical Trials - Surgical
(Trocar Site) Scars
 
 

 
14
AZX100 Phase 2a Clinical Trial in
Surgical (Trocar Site) Scars
One Study:
           ► OL-ASCAR-03: 3.0, 10.0 mg or placebo
Objective:
           ► Scar reduction in trocar sites
Study Design:
           ► Comparison of three trocar site scars following arthroscopic
             shoulder surgery
           ► Placebo-controlled; n = 150 dosed
           ► Two active doses per patient (intra-patient control)
             3.0 mg, 10.0 mg
           ► Placebo-only cohort (n=25)
           ► Two intradermal injections into each trocar site
                   ● 9 ± 2 days following surgery
                   ● 21 ± 2 days following surgery

OL-ASCAR-03:
      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)
                     ● 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)

Is AZX100 a Viable Candidate for
Clinical & Commercial Development?
 Novel Mechanism
                ►Anti-fibrotic
 Strong Patent Position

                ►Demonstrated Safety
                ►Observed Signal of Efficacy Across Multiple Time Points
 Cost-Effective Manufacturing Process
 Market Potential
                ►Multiple Indications
                      ● Dermal Scarring; Other Fibrotic Disorders (e.g., IPF)
                ►Benefits in Scarring: “Faster / Stronger / Smaller”
                ►Large Market
                      ● 22.5 Million Procedures Performed Annually in U.S. Alone
                      ● Estimated Addressable Market >$1.0 Billion
                ►Prophylactic Standard of Care in General Surgery
                ►Reimbursement for Problem Scars (Keloid)
 
 

 
17
Is AZX100 a Viable Candidate for
Clinical & Commercial Development?
 Answer:
         ► Capstone believes the AZX100
           development program in
           dermal scarring should be continued
 To this end…
          ► Capstone is pursuing a pharma or biotech collaboration to
            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
