The Effect of Trimetazidine on Mitochondrial Function, Myocardial Performance, and Invasive Hemodynamics in Patients Diagnosed With Wild-Type Transthyretin Cardiac Amyloidosis

CACTuS - TMZ
Start date: October 1, 2021
Phase: Phase 4
Study type: Interventional

Wild-type transthyretin cardiac amyloidosis (ATTRwt) is a deposition disorder in which one of the proteins of the body misfolds and accumulates at various places in the body, including the heart, leading to both mechanical and cellular damage. The gradual development of the disease will ultimately lead to heart failure and death The protein which deposits in the heart of patients, damages both the heart mechanically as the myocardium becomes rigid and hypertrophic over time but also at the cellular level. Cell damage can be observed by elevated blood tests for cell damage (Troponin) and during exercise tests that show patients' hearts burning oxygen inefficiently when exposed to physical stress compared with the hearts of healthy individuals . No one has, however, intimately studied this cellular damage. Vastarel® (Trimetazidine, TMZ) is an already known drug for the treatment of chest pain. The mechanism of action indicates that it may have an effect on patients with cardiac amyloidosis. The study aims to investigate the effects of TMZ on the mitochondrial function, myocardial performance, and invasive hemodynamics in patients with ATTRwt with a randomized, double-blinded, crossover-trial.

NCT ID: NCT05162768 Active, not recruiting - Clinical trials for Mitochondrial Diseases

Study to Evaluate Efficacy and Safety of Elamipretide in Subjects With Primary Mitochondrial Disease From Nuclear DNA Mutations (nPMD)

NuPower
Start date: April 29, 2022
Phase: Phase 3
Study type: Interventional

SPIMD-301 is a 48-week, randomized, double-blind, parallel-group, placebo-controlled trial to assess efficacy and safety of single daily subcutaneous (SC) administration of elamipretide as a treatment for subjects with primary mitochondrial myopathy associated with nuclear DNA mutations (nPMD).

NCT ID: NCT04379934 Not yet recruiting - Heart Failure Clinical Trials

Functional and Metabolic Effects of Ketone Bodies on Human Atrial Tissue in Patients With and Without Heart Failure

Start date: June 1, 2020
Phase: N/A
Study type: Interventional

This proof of concept study aims to evaluate the effects of applying ketone bodies to human atrial tissue biopsies using an atrial strips model and high resolution respirometry.

NCT ID: NCT04322734 Not yet recruiting - Epilepsy Clinical Trials

Transgenerational Metabolic-Immune Biomarkers of Neurological and Neurodevelopmental Disorders

Start date: July 1, 2024
Phase:
Study type: Observational

Researchers in the Neurodevelopmental Division at Phoenix Children's Hospital are conducting a study about mitochondrial function in children with autism spectrum disorder (ASD). The study involves up to 5 visits to Phoenix Children's Hospital with fasting blood draws, behavioral assessments, and/or questionnaires. Other samples may be collected when appropriate. This study is currently recruiting. There is no cost for visits or study-related exams.

NCT ID: NCT03704311 Completed - Myofascial Pain Clinical Trials

Evaluation of Mitochondrial Function in Myofascial Trigger Points Cohort Pilot Study Using High-resolution Respirometry

MitoTrigger
Start date: October 1, 2013
Phase: N/A
Study type: Interventional

This pilot study established a minimally invasive biopsy technique to obtain high-quality MTrP tissue samples to evaluate mitochondrial function via high-resolution respirometry.

NCT ID: NCT03344913 Completed - Pain Clinical Trials

Biologic Mechanisms for Pain Variation After Physical Activity in Osteoarthritis

Start date: May 7, 2018
Phase: N/A
Study type: Interventional

Osteoarthritis (OA) in the knee is characterized by chronic inflammatory pain that is not necessarily related to the amount of joint damage. Clinical practice guidelines recommend physical activity (PA) for osteoarthritis pain, but most adults with OA do not engage in PA. One reason for this is that while PA can reduce OA related joint pain, it does not work for everyone. PA decreases pain sensitivity for about half of adults with OA but increases pain sensitivity for the other half. The investigators are hypothesizing that individual differences in how well cells work to make energy, inflammation, and different proteins available in blood cells explains who PA will work to reduce pain and who it won't among adults with OA. The purpose of this pilot study is to determine if blood cells' ability to make cellular energy, inflammation and proteins help explain the difference about who PA reduces activity for and who it doesn't. The investigators will compare these biologic factors and pain sensitivity before walking, immediately after 30 minutes of walking (i.e. "acute") and after six weeks of walking three times a week for 30 minutes (i.e. "long-term") in adults with hip or knee osteoarthritis. The investigators will also compare these results to adults without OA. The investigators will recruit a sample of 40 adults with radiologic (e.g x-ray or CT scan) evidence of hip or knee OA and 20 age/gender matched healthy adults without OA to address the following study aims: Aim 1: To examine the effects of a six week (three days/week) walking program on pain in adults with OA as compared to healthy controls. Aim 2: To test the cells' ability to make energy as a mechanism for variation in pain after "acute" and "long-term" PA in older adults with lower extremity osteoarthritis. Aim3: To test the role of inflammation as a mechanism for variation in pain after "acute" and "long-term" physical activity in adults with lower extremity osteoarthritis. Aim 4: To generate hypotheses regarding the role of proteomics in variation in pain after "acute" and "long-term" physical activity.
