GALAXY

GALAXY Registry

Long-term Evaluation of the Linox Family ICD Leads Registry

Study Design

  • Multi-center , prospective, non-randomized, FDA reviewed, observational study
  • Designed to confirm long-term safety and reliability of BIOTRONIK’s Linox ICD leads
  • 1,997 patients at 98 USA centers - This study is ongoing

Recent publication1 with results from the ongoing GALAXY and CELESTIAL studies demonstrate favorable lead survival probabilities

Clinical Relevance

  • Linox and Linoxsmart ICD leads are safe, reliable and infrequently associated with lead-related adverse events (AEs)
  • Estimated cumulative survival probability is favourable and well within industry standards
  • Scientifically sound analysis due to multi-center, high enrollment, prospective study design as well as adjudication of AEs by an independent panel of five EPs
  • Most extensive description of performance, safety and longevity of Linox ICD leads published to date

1° endpoints
  • To evaluate the overall incidence of serious adverse events related to the Linox family of ICD leads
  • To evaluate the incidence of each type of serious adverse event that contributes to the above point
2° endpoints
  • Serious adverse event rates for SAEs excluded from primary safety endpoint through 5 years post-enrollment
  • Electrical characteristics of each individual Linox lead system, measured at scheduled GALAXY registry follow ups through 5 years post-enrollment
Clinical Sites
  • 98 centers, 75 active
Sample Size
  • 1,999 patients
