MOMENTUM 3 IDE Clinical Study Protocol

Overview

  • Study type

    Interventional
  • Study phase

    III
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The objective of the study is to evaluate the safety and effectiveness of the HM3 LVAS by demonstrating non-inferiority to the HMII LVAS (HMII) when used for the treatment of advanced, refractory, left ventricular heart failure.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

  2. Technical obstacles which pose an inordinately high surgical risk, in the judgment of the investigator
  3. Existence of ongoing mechanical circulatory support (MCS) other than IABP
  4. Positive pregnancy test if of childbearing potential
  5. Presence of mechanical aortic valve that will not be either converted to a bioprosthesis or oversewn at the time of LVAD implant
  6. History of any organ transplant
  7. Platelet count < 100,000 x 103/L (< 100,000/ml)
  8. Psychiatric disease/disorder, irreversible cognitive dysfunction or psychosocial issues that are likely to impair compliance with the study protocol and LVAS management
  9. History of confirmed, untreated AAA > 5 cm in diameter within 6 months of enrollment
  10. Presence of an active, uncontrolled infection
  11. Intolerance to anticoagulant or antiplatelet therapies or any other peri/post-operative therapy the investigator will require based upon the patients' health status
  12. Presence of any one of the following risk factors for indications of severe end organ dysfunction or failure:
    1. An INR ≥ 2.0 not due to anticoagulation therapy
    2. Total bilirubin > 43 umol/L (2.5 mg/dl), shock liver, or biopsy proven liver cirrhosis
    3. History of severe chronic obstructive pulmonary disease (COPD) defined by FEV1/FVC < 0.7, and FEV1 <50% predicted
    4. Fixed pulmonary hypertension with a most recent PVR ≥ 8 Wood units that is unresponsive to pharmacologic intervention
    5. History of stroke within 90 days prior to enrollment, or a history of cerebrovascular disease with significant (> 80%) uncorrected carotid stenosis
    6. Serum creatinine ≥ 221 umol/L (2.5 mg/dl) or the need for chronic renal replacement therapy
    7. Significant peripheral vascular disease (PVD) accompanied by rest pain or extremity ulceration
  13. Patient has moderate to severe aortic insufficiency without plans for correction during pump implant
  14. Pre albumin < 150 mg/L (15mg/dL) or Albumin < 30g/L (3 g/dL) (if only one available) ; pre albumin < 150 mg/L (15mg/dL) and Albumin < 30g/L (3 g/dL) (if both available)
  15. Planned Bi-VAD support prior to enrollment
  16. Patient has known hypo or hyper coagulable states such as disseminated intravascular coagulation and heparin induced thrombocytopenia
  17. Participation in any other clinical investigation that is likely to confound study results or affect the study
  18. Any condition other than HF that could limit survival to less than 24 months
