MS: Relapsing - Remitting MS Phase II Clinical Trial of Trimesta TM (oral estriol) • Multi - center, investigator - initiated, randomized, double - blind, placebo - controlled trial ̶ Comparing relapse rates over 2 years between 8 mg of oral Trimesta TM taken daily versus matching placebo ̶ All patients treated with Copaxone ® as standard of care ̶ Enrollment complete: 164 patients at 15 U.S. centers ̶ Topline results expected 1H 2014 • Largest MS Society grant (total grants $8 million+) ̶ Phase II trial in women with relapsing - remitting MS 3 funded to completion • Rhonda Voskuhl , M.D., UCLA Department of Neurology ̶ Trimesta TM key opinion leader / lead principal investigator 9 Copaxone ® is a registered trademark of Teva Pharmaceutical Industries Ltd.
Emerging Worldwide Crisis 10 Multidrug - resistant infectious diseases “Infections were the second leading cause of death worldwide in 2002, killing nearly 15 million people – almost 1 in 3 deaths across the globe ” “Multidrug - resistant (MDR) microbes infect more than 2 million Americans each year, killing over 100,000 people ” Brad Spellberg, M.D., author of the book, Rising Plague 4
Revolutionize Infectious Disease Treatment • Infectious disease outbreaks increasing while intervention options decline 5 ̶ Widespread MDR pathogens ̶ Increasing numbers of immuno - compromised patients • Utilize targeted biologics approach – similar to cancer drugs • Large and growing markets – significant unmet medical need • Counter - cyclical strategy – limited big pharma investment • GAIN Act: Enhances regulatory pathway for novel infectious disease treatments ̶ 5 years of additional market protection, fast track and accelerated NDA reviews • Opportunity to monetize/partner programs 11
12 • Infections caused by C. diff in the U.S. (2009) resulted in: ̶ 337,000+ hospitalizations 6 ̶ Cost per patient $24,000 ̶ 30,000 deaths 6 ̶ $8.2 billion in costs associated with C. diff - related stays in the hospital 7 ̶ Increasing incidence and often multidrug - resistant • C . diff toxins cause serious diarrhea and in some cases death • Leading cause of hospital acquired infections (HAIs) C. difficile : Market Overview Impact on patients and growing economic burden There are currently no approved products for the prevention of C. diff infections
13 Infectious Disease: Clostridium difficile (C. diff) Acquired clinical - stage program November 2012 • Prophylactic treatment for prevention of C. diff infection • First generation candidate (formerly known as P1A), a proprietary oral enzyme co - administered with certain penicillins , eliminated the antibiotics from the GI tract and protected the native microflora ̶ Phase I and II studies demonstrated safety, tolerability and efficacy ▪ Maintained natural GI microflora balance ▪ Remained in the GI tract – did not cross over into blood stream • Develop SYN - 004, a next generation product designed to protect the GI tract microflora from penicillins and, in addition, most cephalosporins (the antibiotics most commonly associated with C. diff infection) ‒ ~ 8.7 million Americans administered IV β - lactam antibiotics in 2011 8
