Clinical Trial Summary

This will be the first, definitive, randomized control trial (N=424) to test the hypothesis that the Jada® System is effective, safe and cost-effective in treating PPH, compared to standard care.


Description:

Every year, 130 million women deliver babies around the world, and an estimated 14 million (11%) experience postpartum hemorrhage (PPH), recently redefined as a cumulative blood loss of 1000 ml or more or blood loss associated with signs or symptoms of hypovolemia, irrespective of the route of delivery. PPH is the leading cause of maternal mortality worldwide, responsible for 25% of maternal deaths from obstetric causes, with 99% occurring in low and middle income countries (LMICs). Although PPH has multiple causes, the most common is uterine atony when the uterus fails to adequately contract after childbirth, accounting for 70% of all PPH. Active management of the third stage of labor, consisting of administering prophylactic uterotonics, controlled cord traction, and uterine massage after delivery, reduces the incidence of PPH by approximately 66%. These conservative measures facilitate the normal postpartum tetanic myometrial contractions that constrict the placental bed vasculature. When PPH occurs in spite of these preventive measures, therapeutic options include additional uterotonics (medical), uterine tamponade (mechanical) and surgical interventions (vascular ligation, uterine compression sutures and hysterectomy). Uterine balloon tamponade is often the second line therapy when medical management is unsuccessful and is achieved with inflatable devices inserted into the uterus to exert outward compression on the uterine walls. Despite its widespread use, its mechanism is counterintuitive to the physiologic uterine contraction that occurs after delivery to control bleeding. Its use is further limited by prolonged treatment times (typically 12-24 hours), urinary tract occlusion, and inability to reveal any continuing bleeding. Low-cost options most commonly condom catheters are used in LMICs, but two recent randomized trials showed no improvement in maternal outcomes and possible harm. Thus, there is an urgent need for effective and safe treatment options to reduce the burden of PPH particularly in LMICs. The Jada® System (Alydia Health, Menlo Park, CA, USA) is a novel U.S. FDA-cleared intrauterine vacuum-induced hemorrhage-control device specifically designed for rapid treatment of PPH. It mimics postpartum physiology by applying low-level intrauterine negative pressure to facilitate uterine compressive forces for constriction of blood vessels to achieve hemostasis. Preliminary data from two studies have shown promising results. The device was first evaluated in a feasibility case series (n=10) in Indonesia and showed rapid treatment of abnormal postpartum uterine bleeding.6 The second larger study, a multicenter single-arm trial (n=106) in the United States, confirmed quick and definitive control of bleeding in 94% of cases within a median time of 3 minutes and few adverse events. While promising, these data are limited by lack of control groups, possible selection bias and the modest sample sizes which preclude definitive conclusions regarding the relative effectiveness and safety of the Jada® System. We propose the first, definitive, randomized control trial (N=424) to test the hypothesis that the Jada® System is effective, safe and cost-effective in treating PPH, compared to standard care. A multidisciplinary team of investigators with expertise in obstetrics, global health and clinical trials will enroll 424 women in two high volume obstetric units in Ghana, a LMIC with high PPH burden, to pursue the following specific aims: Primary Aim: Evaluate the effectiveness of the Jada® System, compared to standard care, in treating PPH. Secondary Aim 1: Assess the safety of the Jada® System, compared to standard care, in treating PPH. Secondary Aim 2: Estimate the cost-effectiveness of the Jada® System, compared to standard care, in treating PPH.

Intervention

Device:
Jada® System
This is a U.S. FDA-cleared device intended for treatment of PPH when conservative management is warranted. The device is made of medical grade silicone. The distal end, which is placed in the uterus, is an elliptical loop. The circular cervical seal, just outside the external cervical os, is filled with 60 - 120 mL sterile water. Low-level vacuum (80 ± 10 mm Hg) is applied and pooled blood is evacuated from the uterus as it collapses. Once there is no bleeding, the device remains in the uterus for at least 1 hour. The suction is then disconnected, the seal emptied of water, the device left in place, and the patient monitored for an additional 30 minutes. If bleeding remains controlled, the device is removed. If bleeding is uncontrolled with the Jada® System patients will have surgical intervention with options of uterine vascular ligation, uterine compression sutures or hysterectomy.
Other:
Standard care
Patients in this group will receive care according to the treatment algorithm for PPH from uterine atony at the two teaching hospitals in Ghana. Possible interventions include additional uterotonics, tranexamic acid, and condom catheter balloon uterine tamponade. If bleeding is uncontrolled, patients will have surgical intervention with options of uterine vascular ligation, uterine compression sutures or hysterectomy.
