  Purpose

To study the safety, immunogenicity and efficacy of an investigational H. pylori vaccine, compared with placebo.


Condition Intervention Phase
Helicobacter Pylori Infection
Biological: H.pylori vaccines
Biological: Placebo Vaccine
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Single Blind (Subject)
Primary Purpose: Prevention
Official Title: Phase I/II, Randomized, Observer-blind, Placebo-controlled, Single-Center Study of the Tolerability, Immunogenicity, and Efficacy of an Novartis' Investigational H. Pylori Vaccine in H. Pylori-Negative Adults

Further study details as provided by Novartis:

Primary Outcome Measures:
  • Efficacy (defined as prevention of infection) of the HP vaccine candidate vs. placebo. [ Time Frame: 6-12 months ] [ Designated as safety issue: No ]
  • To assess the tolerability of an HP vaccine vs placebo. Measures to evaluate safety will include monitoring of local and systemic adverse events and clinical laboratory tests. [ Time Frame: 6-12 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To define the HP-specific humoral and cellular immune responses among vaccinees versus placebo recipients. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • To identify potential immune markers to distinguish HP vaccination from natural HP infection. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • To correlate mucosal and systemic cellular immune responses as assessed by sampling of gastric mucosa and peripheral blood cells, respectively [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • To define potential immune correlates of protection. [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
