Preliminary Percutaneous Intervention Versus Observational Trial of Arterial Ductus in Low-weight Infants (PIVOTAL)
February 5, 2024 updated by: Carl Backes, MD, Nationwide Children's Hospital
Preliminary Percutaneous Intervention Versus Observational Trial of Arterial Ductus in Low-weight Infants (PIVOTAL)
This is a pilot study to collect preliminary data for a larger, multicenter clinical trial proposal.
The study will examine two strategies commonly used to treat preterm infants diagnosed with a patent ductus arteriosus (PDA).
The PDA closes after birth for most term infants, but in many preterm infants, it remains open (patent).
A PDA may present a complication for a number of short-term problems faced by preterm infants.
Longer-term issues include the development of pulmonary hypertension and changes in the size and performance of the heart.
There is ongoing debate as to whether or not the PDA requires intervention.

Conditions
Detailed Description
Preterm infants diagnosed with a hemodynamically-significant patent ductus arteriosus (HSPDA) will be included.
Specific criteria will be followed to determine if a patent ductus arteriosus (PDA) is "hemodynamically significant".
Infants will be randomized to two different approaches for management of the PDA.
The first will be catheter-based closure (intervention) and the second will be conservative management (non-intervention).
Both procedures are standard practice at many institutions, including Nationwide Children's Hospital.
Infants randomized to receive intervention will undergo a procedure in which a catheter is used to place an FDA-approved device within the PDA, to close it (like a plug).
Infants randomized to the conservative management (non-intervention) group will be permitted time to see if the PDA closes on its own, naturally.
However, if the PDA remains open and intervention is deemed medically necessary, they will also undergo the catheter closure procedure.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
1 year to 1 year (Child)
Accepts Healthy Volunteers
No
Description
Maximum age (above) indicates qualifying / eligibility criteria. Participating infants will be followed until they reach 36 weeks corrected gestational age OR are discharged from the hospital, whichever comes first.
Inclusion Criteria:
- Preterm infants ≤28 weeks gestational age with hemodynamically-significant patent ductus arteriosus (PDA) at 2 - 4 weeks of age.
- Body weight greater than or equal to 700 grams
Exclusion Criteria:
- Significant genetic (ex.- Trisomy) or physiological (ex. - Omphalocele) abnormalities
- Other cardiac disease NOT INCLUDING atrial-septal defects or ventricular septal defects (ex. Tetrology of Fallot, Single ventricle physiology)
- Body weight less than 700 grams

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Catheter-closure of PDA
Infants randomized to this group will undergo a catheter procedure to close hemodynamically-significant patent ductus arteriosus (HSPDA).
|
Infants assigned to this group will have a catheter run from a blood vessel in the upper leg / groin area to the heart, where an FDA-approved device will be placed within the patent ductus arteriosus to occlude or plug it, thereby closing the ductus.
Other Names:
|
Active Comparator: Conservative management of PDA
Infants randomized to this group will be treated to reduce the symptoms of a hemodynamically-significant patent ductus arteriosus (HSPDA), in the hopes that over time the HSPDA will become reduced in size (to the point of no longer meeting criteria for being "hemodynamically significant") or close naturally.
Infants in this group with declining health status attributable to a PDA which meet qualifying criteria may receive catheter closure (intervention) if deemed medically necessary.

Infants assigned to this group will have a catheter run from a blood vessel in the upper leg / groin area to the heart, where an FDA-approved device will be placed within the patent ductus arteriosus to occlude or plug it, thereby closing the ductus.
Other Names:
Infants with a hemodynamically-significant patent ductus arteriosus randomized to this group will be treated by fluid restriction and possible diuretic use to reduce PDA symptoms, and allow time to permit the PDA to close or become reduced in size to the point where it is no longer considered "hemodynamically-significant".
