About this trial

Preeclampsia is a leading cause of maternal and neonatal morbidity and mortality. There is a lack of effective therapeutics for prevention or treatment. Our previous ex vivo work demonstrated that mitochondrial-antioxidants can reverse placental microvascular damage. Therefore, this study will evaluate whether MitoQ (Mitoquinol Mesylate, a mitochondrial-antioxidant) has the potential to restore vasodilation, improve placental function, and therefore promote pregnancy prolongation in patients with gestational hypertension (gHTN) and/or preeclampsia. This evaluation of clinical data, patient samples, and vascular function studies in patients with gHTN and/or preeclampsia could translate into a viable therapeutic option.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

gestational age between 23+0 and 33+0 weeks' gestation

singleton pregnancy

Disqualifiers

Unable to stand from chair without physical assistance from another person (able to use assistive device).

Trial design

Design model

Parallel

Treatments tested in this trial

  • Mitoquinol Mesylate

    Dietary supplement

    Patients randomized to the intervention will receive 10mg of Mitoquinol Mesylate daily from enrollment until delivery.

  • Placebo

    Other intervention

    Patients randomized to the placebo groups will take 1 placebo capsule daily until delivery.

Treatment groups

80 Participants
are divided into 4 treatment groups
Group A: Preeclampsia with Severe Features taking Mitoquinol MesylateExperimental treatment 1 intervention
Group B: Preeclampsia with Severe Features taking placeboPlacebo comparator 1 intervention

Group D: Preeclampsia without Severe Features or Gestational Hypertension taking placeboPlacebo comparator 1 intervention

Trial outcomes

Primary outcomes

1

Brachial Artery Flow Mediated Dilation (FMD)

We will measure brachial artery vascular health in the arm. Baseline brachial artery diameter and blood flow velocity through the artery will be measured before and after a pneumatic forearm cuff is inflated to 225 mmHg for five minutes.

Time frame
1-2 times per week from enrollment until delivery, up to 10 months

Secondary outcomes

1

Cutaneous Microvascular Function

Laser Doppler Flowmetry (LDF) will measure blood flow flux during local skin heating to examine microvessel vasodilation

Time frame
1-2 times per week From enrollment until delivery, up to to months.
2

Placental Microvascular Function

After delivery, placental vessels will be isolated from the placenta and a videomicroscopy technique will be used to evaluate flow-mediated dilation in vessels from placebo and MitoQ treated pregnancies.

Time frame
At Delivery
3

Time from Enrollment to Delivery

Time from diagnosis and initiation of MitoQ or placebo to delivery

Time frame
Time in days from enrollment to delivery, up to 10 months
4

Blood Draw

We will collect blood each week. The blood draw analysis may include but will not be limited to examining sFlt:PlGF ratio, plasma redox and bioenergetic analyses.

Time frame
Weekly from enrollment until Delivery, up to 10 months
