Investigator-Initiated Research

What is Investigator Initiated Research?
Investigator Initiated Research (IIR) studies are designed and conducted independently by investigators who also serve as the study sponsor. As the sponsor, the investigator assumes all responsibilities for complying with applicable regulatory requirements. IIR may be supported by LivaNova in the form of product, funding and/or technical input.

Key Areas of Interest for Investigator Initiated Research


(1) Early vs Late use of VNS in DRE: Retrospective analyses evaluating clinical outcomes and healthcare utilization in patients with DRE receiving early (for example: within 5 years of DRE onset) versus late (including post-resection) intervention with VNS Therapy.

(2) Optimization of VNS settings: Case series of optimization of VNS settings and titration schedules on seizure control and adverse event profile with a special interest in pediatric outcomes.

(3) Comorbidities: Case series and retrospective studies evaluating changes in mood, depression, and/or cognition using validated instruments in patients with DRE treated with VNS Therapy.

(4) Exploratory indications: Case series and retrospective studies exploring additional benefits of VNS Therapy.

General considerations for all areas of interest:

  • Analysis of existing patient databases that have been systematically collected as part of an ongoing evidence generation program are highly desirable (for example The Epilepsy Learning Healthcare System (ELHS), pELHS (pediatric Epilepsy Learning Healthcare System), and International Consortium for Health Outcomes Measurement (ICHOM)).
  • Clinical outcomes of interest: seizure frequency, seizure severity, mortality, injury, quality of life (both disease specific and generic health status measures such as EQ5D), depression, cognition, loss of function, and failure to achieve developmental milestones (validated assessments preferred).
  • Patient Reported Outcome Measures (PROMs) measuring the patients’ views of their health status are welcomed.
  • Inclusion of Patient Reported Experience Measures (PREMs) measuring the patients’ perceptions of their experience are encouraged.
  • Societal impact outcomes of interest include education, employment, productivity and socio-economic impact of DRE on caregivers and patients.
  • Investigator Initiated Research that evaluates the use of a device that is not in accordance with the approved labeling requires prior approval from the relevant Competent Authority. See LivaNova’s Physician Manual and product labeling for a full listing of Indications, Contraindications, Warning and Precautions. 

 Advanced Circulatory Support

(1) Studies that quantify the outcomes of RA-PA Dual Lumen Cannulation with oxygenation in patients with acute respiratory failure. Clinical and economic outcomes to quantify and compare the efficacy and safety of ProtekDuo vs conventional veno-veno cannulation. Clinical outcomes including early ambulation, RV function, mechanical ventilation dependency, ability to connect or disconnect the oxygenator without interruption of support, ICU length of stay, total length of stay, recovery time, hospital costs, staff dependency, complications, and mortality are of interest. Economic analyses may include cost effectiveness analyses, cost consequence analyses, and budget impact models.
(2) Studies that compare VA-ECMO using LifeSPARC to other temporary percutaneous heart pumps in patients with acute cardiac insufficiency. Clinical and economic outcomes to quantify and compare the efficacy, safety, and healthcare utilization for patients treated with LifeSPARC compared to other heart pumps. Clinical outcomes including time to ambulation, blood product use, central venous pressure, recovery time, ICU length of stay, total length of stay, hemodynamic parameters, complications, and mortality are of interest. Economic analyses may include cost effectiveness analyses, cost consequence analyses, and budget impact models.

(3) Usability studies that evaluate the implementation of an ECMO program utilizing LifeSPARC. Usability and clinical outcomes to quantify and compare the ease of use of the ECMO program using LifeSPARC. Outcomes including set up time, rapid initiation, number of FTE required to implement the program, staff dependence (total cost of support staff). Key interests include the correlation of rapid initiation and with clinical and economic outcomes, number of staff to manage the device and patient post insertion, cost savings compared to conventional programs.
To be eligible to receive support for IIR, the following conditions must be met: 

1) The research for which support is being sought must be within the therapeutic areas that are served by LivaNova. Proposals that are aligned with the areas of interest set out above will receive the highest priority for review and funding.

2) Applications must be submitted by or on behalf of a legal entity/organization - funds/products can only be provided to organizations, and not individuals acting on their own.

3) All required information and supporting documentation must be provided. LivaNova may reach out to the applicant with follow up questions in relation to the provided material. Incomplete requests may be rejected or delayed.
