  83. Slide 83: SYN-010: No Meaningful or Persistent Systemic Effects

    SYN - 010 No Meaningful or Persistent Systemic Effects Consistent with reduced systemic exposure to lovastatin β - hydroxyacid • Plasma trough levels of lovastatin species measured during the RCT were low and variable¹ • ≥50% of patients had undetectable plasma trough levels of each analyte on days

  84. Slide 84: SYN-010 Clinical Outcomes

    • Daily doses of SYN - 010 were well - tolerated by IBS - C patients over a 12 week treatment period in Phase 2a clinical trials¹ , ² • No SAEs, few TEAEs, no drug - related diarrhea • Compelling improvements were observed in bowel movement frequency, abdominal pain and bloating in IBS - C patients

  85. Slide 85: Symptom Responses in the Open-Label Extension

    • Placebo responses during the RCT • 0% Overall Response is possible if the CSBM response and abdominal pain response do not occur in the same week • Increased responses upon transition to the open - label EXT are not a Placebo effect of unblinding the dose • Increase in response was observed for al

  86. Slide 86: SYN-010 Clinical Development Status

    • FDA recommended a first Phase 2b/3 adaptive clinical trial • N=840 (280/arm) • Multicenter, randomized, double - blind, placebo - controlled study • Single daily doses of Placebo, SYN - 010 (21 mg) or SYN - 010 (42 mg) for 12 weeks • Both low and high - breath methane patients to be included • FDA

    SYN - 010 Pivotal Clinical Trials in IBS - C ¹Interim futility analysis based on dose may be conducted after 50% of subjects have completed 12 weeks. ²An Overall (12 - Week) Responder has a Weekly Response in at least 50% of weeks in the 12 - week treatment period. A Weekly Respons e is defined as a

  89. Slide 89: Why Include Low Breath Methane Patients?

    IBS - C patients with low breath CH 4 but high gut CH 4 should also benefit from SYN - 010¹ Why Include Low Breath Methane Patients? ¹Kim G et al. (2012) Dig Dis Sci 57: 3213 - 8 ; the population prevalence of IBS - C patients with low breath CH 4 but constipating gut CH 4 has not been established.
