Corox OTW, Endocardial, Left Ventricular Steroid Lead, Bipolar Post Approval Registry

Study Design

  • Multi-center, prospective, non-randomized, FDA reviewed, observational study1
  • Designed to gather long-term safety and reliability data on BIOTRONIK’s Corox BP LV leads
  • 2,499 patients at 97 USA centers - This study is ongoing

Key Result

The CELESTIAL registry focuses primarily on the performance of Corox leads (n=2,499), however, the majority of patients received a CRT-D system including a Linox or Linoxsmart ICD lead (n=1,843)

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 favorable 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 Corox BP LV leads
  • To evaluate the incidence of each type of serious adverse event that contributes to the above point
2° Endpoints
  • Successful biventricular pacing in a BIOTRONIK CRT device at scheduled CELESTIAL registry follow-up through 5 years post-enrollment
  • Serious adverse event rates for SAEs excluded from primary safety endpoint through 5 years post-enrollment
  • Pacing threshold, sensing, and impedance measurements for Corox BP leads at scheduled CELESTIAL registry follow-up through 5 years post-enrollment
Clinical Sites
  • 99 centers, 78 active
Sample Size
  • 2,499 patients
