NC-002 Summary of Key Results and Next Steps 2014 International AIDS Conference • Pa-M-Z Regimen was statistically significantly better than the H-R-Z-E control for the primary and 3/5 key secondary endpoints • Greater reduction in colony counts over 56 days • More rapid time to culture conversion • Higher conversion to negative at 8 weeks – Nearly twice the number converted in liquid culture • No significant difference in response for HIV infected patients • Similar effects for patients with MDR-TB, albeit with small numbers • Safety comparable to control • Next Step: The STAND Phase 3 Trial
The STAND Trial - Phase 3 Trial of Pa-M-Z“Shortening Treatment by Advancing Novel Drugs” Pa(100mg)-M-Z N=300 4months of treatment Pa(200mg)-M-Z N=300 12 & 24 mos f/u after randomization DS H-R-Z-E N=300 Pa(200mg)-M-Z N= up to 300 6months of treatment Randomize DR Z = pyrazinamide at 1500mg Pa = PA-824 M = moxifloxacin 400 mg 2014 International AIDS Conference Participants with newly diagnosed smear positive DS- and MDR-TB Pa(200mg)-M-Z N= 300
