Safe Harbor Statement


AmpioPharmaceuticals Overview

Ampio Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the discovery and development of novel therapies aimed at treating common inflammatory conditions for which there are limited treatment options.

We are developing compounds that serve significant medical needs in osteoarthritis, diabetic macular edema, and other prevalent, inflammatory diseases through an innovative discovery and development platform.


Ampio’s Late-Stage Pipeline Overview

Ampio has advanced its lead development assets into late-stage, pivotal clinical trials in the US.


Ampion for Osteoarthritis of the Knee (OAK)

Ampion is a novel biologic with a unique MOA.

  • Low molecular weight fraction of commercial human serum albumin (HSA)
  • Aspartyl-alanyldiketopiperazine (DA-DKP) primary constituent ingredient1
    • Demonstrates significant efficacy across broad spectrum of OAK patients graded Kellgren-Lawrence II through IV – radiographic OA grading instrument
    • Established and extensive safety profile with no treatment-related adverse events

Ampion has high barriers to competitive entry.

  • 3 patent families consisting of 44 issued patents and 42 pending patents
  • Strong composition of matter claims
    • Pharmaceutically-acceptable carrier and DA-DKP
    • Filtrate produced by passing a solution of a protein or peptide over an ultrafiltration membrane with a molecular weight cutoff that retains albumin
  • 12 years data BLA exclusivity on US upon approval & long-term supply agreement

D. Bar-Or, et al, Commercial human albumin preparations for clinical use are immunosuppressive in vitro, Crit Care Med 34 (2006) 1707-1712.


New Facility: Scaling Up Production

  • Capacity to produce 10 million+ vials/annum
  • Easily operate at 8 million vials per annum
  • Production lots of ~10,000 vials
    • 50 L HSA, 85-89% filtration yield = 10,241 to 10,723 vials/lot

The first Ampion pivotal SPRING Study is complete, with robust clinical improvement across a broad range of OAK patients.

SPRING Study Design Summary:

  • 9 centers, N=329, randomized 1:1:1:1, double-blind, parallel group
  • Ampion 4 mL vs. saline 4mL & Ampion 10 mL vs. saline 10 mL
  • Rapid completion – enrollment completed in less than 4 weeks
    • Study initiation date: March 29, 2013
    • Study completion date: August 19, 2013
  • Primary efficacy endpoint: difference in pain reduction as measured by WOMAC A subscale at 12 weeks
    • 20 week ad hoc follow-up to determine duration of effect
  • Efficacy determined by WOMAC and PGA
  • Safety examined as incidence and severity of AEs

Ampion demonstrated meaningful, statistically significant improvement in pain, function, and quality of life with no treatment-related AEs.

  • Patients receiving Ampion achieved:
    • Greater reduction in pain (WOMAC A) from baseline to 12 weeks compared to saline vehicle control (p = 0.0038)
    • Mean reduction in pain of 42% from baseline
    • Significantly greater improvement in function (WOMAC C) from baseline to 12 weeks compared to saline vehicle control (p = 0.044)
    • Significantly greater improvement in overall quality of life measures (Patient Global Assessment) from baseline to 12 weeks compared to saline vehicle control (p = 0.012)
  • Clinical efficacy was observed as early as four weeks and sustained through 20 weeks in subset analysis
    • 4 mL Ampion dose selected for second pivotal study
    • WOMAC A mean difference from saline control (p=0.025)
  • Ampion was well tolerated with minimal adverse events and no drug-related serious adverse events

Second AmpionPivotal Trial: STEP Study

STEP Study Summary:

  • 17 centers, N=538, randomized 1:1, double-blind, parallel group
    • Power to demonstrate a significant treatment effect is 90%
  • Ampion 4 mL vs. saline 4mL
    • Stratified by KL 2 (~25%) and KL 3 / 4
  • Rapid completion – enrollment completed in less than 2 months
  • Primary efficacy endpoint: difference in pain reduction as measured by WOMAC A subscale at 12 weeks
    • 20 week follow-up to determine duration of effect
  • Efficacy determined by WOMAC and PGA
  • Safety examined as incidence and severity of AEs

STEP Study: Milestones at a Glance

  • First Patient First Visit: January 9th, 2014
  • Last Patient First Visit: February 21st, 2014
  • Last Patient Last Visit (12 weeks): ~May 22nd 2014
  • Last Patient Last Visit (20 weeks): ~July 17, 2014
  • Data Readout: Q3 2014
    • BLA Submission to Follow

Optina (ultra low-dose danazol)

Optina has a demonstrated clinical effect in diabetic macular edema.

  • Optina is a fat soluble low molecular weight weak androgen that affects vascular permeability through the endothelial barrier in a biphasic manner1
  • Inhibits vascular permeability by stimulating formation of cortical actin ring and binding molecules1
  • Demonstrated improvement in central retinal thickness in initial clinical trial, with strong treatment signal observed in current OPTIMEYES Study

Optina has strong IP protection with high barriers to entry.

  • 2 patent families consisting of 40 issued patents and 44 pending patents
    • Newly discovered mechanism of action enables broad intellectual property position
    • Angiogenesis and vascular permeability are distinct phenomena
    • It is surprising and unexpected that danazol affects vascular permeability at low doses and that the dose of danazol required for treating vascular permeability is different from the dose required for treatment of angiogenesis

OptimEyes Study Summary: AP-05-002

AP-05-002 Study Design Summary:

  • 22 centers, N=450, randomized 1:1:1, double-masked
  • Total Enrolled: 347 subjects (as of 5/28/2014)
  • Optina (low-dose danazol) oral capsule, 1 mg per BMI, or 0.5 mg per BMI and placebo divided into two daily doses
  • Primary efficacy endpoint: Change in BCVA letters read from baseline to 12 weeks
  • Safety examined as incidence and severity of adverse events and glycemic, liver, renal, lipid, and hormone assays.

An Independent Data Review Committee conducted an interim analysis of the OPTIMEYES Study – with treatment effect observed

Independent Data Review Committee (IDRC) Summary Findings:

  • At least thirty percent (30%) of patients had reached the first 4 week time point and their clinical results; considered representative data for the trial.
  • Analysis parameters were defined a priori and could have resulted in three possible scenarios as follows:
    • Termination of the study due to lack of efficacy or safety concerns
    • Delayed analysis if no conclusion could be drawn
    • Indication of an optimum dose if sufficient differentiation from placebo was present to indicate clinical benefit and no serious adverse events

“After a thorough review of the interim data from the ongoing study, it was determined that there was a treatment dosage that was demonstrating a potentially beneficial anatomic effect. Given that there were no significant safety concerns identified in the study to date, a recommendation to continue the trial was made” OPTIMEYES Study IDRC, September 2013


Oxidation-reduction potential: A ‘vital sign’ assessing the body’s response to oxidative stress

  • Oxidative stress is the body’s response to physiologic stress brought on by a depletion of natural antioxidants in response to:
    • Illness
    • Injury
    • Inflammation
  • While well recognized, no good methods exist to measure oxidative stress.
  • Oxidation-reduction potential is a measure of homeostasis detecting the balance between antioxidants and pro-oxidants in the body.
    • A complete picture of oxidative stress

Luoxis Diagnostics has significantly advanced development of the oxidation-reduction potential (ORP) device platform.

  • Luoxis has a fully-developed IVD asset.
    • Clinical validation studies completed in traumatic brain injury (TBI), multi-trauma, hip fracture, and stroke
    • ISO 13485:2003 certification awarded January 2014
    • Research partnerships in place with major research centers throughout the world
  • Luoxis is moving rapidly toward commercialization.
    • CE Mark obtained in Q1 2014
    • Confidential EU-specific partnering discussions underway
    • First pharma research agreement signed in Q2 2014
