About this study

Official title: The Nutritional Supplement Phosphatidylserine in Patients With Familial

Familial dysautonomia (FD) is a devastating hereditary disease in which the development of selective neuronal populations is impaired because of a deficiency of the protein IKAP (Slaugenhaupt, 2002). There is no known cure. Treatments are supportive, often ineffective and around half of all patients die before reaching age 40 (Axelrod et al., 2002).

Phosphatidylserine is an FDA approved food supplement that was shown recently to correct the genetic abnormality and restore IKAP protein levels in cell lines derived from patients with FD (Keren et al., 2011) and a humanized mouse model of the disease (Bochner et al., 2013). Despite its safety and efficacy in this fragile population being unknown, many patients with FD are currently taking phosphatidylserine

The investigators propose to conduct a safety, tolerability and early proof of concept efficacy study of phosphatidylserine in patients with FD. The study will be divided into two independent arms. The first phase of the study will be an open-label dose titration study to determine the safety and optimal dose of phosphatidylserine and its effect of normal IKBKAP mRNA levels in 40 patients with FD. The second phase will be a longitudinal observational study in which we will follow, on a yearly basis, patients with FD of all ages who opt to take phosphatidylserine. In this study, we will evaluate the long-term safety of phosphatidylserine in patients with FD and hope to determine whether phosphatidylserine has any impact on the clinical evolution of the disorder.

Our long-term goal is to find an effective therapy that will improve the quality of life for patients with FD and alter disease prognosis. We believe that the promise of phosphatidylserine and its availability in health food shops warrants a controlled safety, tolerability and efficacy study to determine whether it should be taken by patients with FD. This study is not intended to determine whether phosphatidylserine has a new indication to treat FD.

Read the detailed description

Familial dysautonomia (FD) is an autosomal recessive disease caused by mutations in the I-B kinase complex associated protein (IKBKAP) gene sequence (Anderson et al., 2001; Slaugenhaupt et al., 2001). The disorder affects the development of sensory nerves, resulting in impaired pain and temperature perception (Riley et al., 1949), lack of visceral sensations (Norcliffe-Kaufmann et al., 2010), dysphagia and proprioceptive gait ataxia (Macefield et al., 2011). Childhood mortality is increased, with aspiration pneumonia a leading cause of death. In early adulthood, renal failure is common (Pearson et al., 1980) and eyesight deteriorates due to optic atrophy and gait ataxia worsens making walking impossible without assistance. The incidence of seizures, scoliosis, respiratory insufficiency, sleep apnea and gastrointestinal bleeds are all increased. Sudden unexpected cardiac deaths are common and there is an increased incidence of cancer. Current treatments are supportive and frequently ineffective. FD has no known cure and 50% of patients die before age 40.

A decade ago, we discovered that the disease was caused by point mutations in IKBKAP gene, leading to a deficiency of I-B kinase complex associated protein (IKAP) mainly in neuronal tissue (Slaugenhaupt et al., 2001; Mezey et al., 2003; Lee et al., 2009). Phosphatidylserine, an FDA-approved food supplement, was shown to increase protein levels in FD-derived cell lines (Keren et al., 2011) as well as in a mouse model of FD (Bochner et al., 2013). Because of the severity of FD, the availability of phosphatidylserine in health food stores and its promise as a treatment, many patients with FD are already taking it, although its safety and efficacy in this population is unknown. Thus, we propose a controlled study of phosphatidylserine to determine its safety profile and whether it has any impact on the natural history of FD.

SPECIFIC AIM 1: It is not known if phosphatidylserine increases the levels of IKBKAP mRNA in patients with FD. To determine the optimal dose of phosphatidylserine in patients with FD, (i.e., the lowest dosage at which there is maximal improvement in IKBKAP mRNA production without significant side effects) we will monitor the safety and efficacy of phosphatidylserine in an open-label dose escalation study. Safety parameters and IKBKAP mRNA levels in blood will be measured in 40 patients with FD at baseline and repeated at increasing doses of phosphatidylserine.

SPECIFIC AIM 2: In an independent long-term observational study, we will follow patients with FD of all ages who opt to take phosphatidylserine as a food supplement in their diet. Safety parameters will be measured as part of routine evaluations on an annual basis. The long-term efficacy of phosphatidylserine will be determined by evaluating the evolution of standard parameters of neurological function overtime in patients who received phosphatidylserine and comparing their progression with historical controls from the database archives.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Phosphatidylserine in people with Familial Dysautonomia, run by NYU Langone Health at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in blood lab values at every 2 month interval (time frame: measurements will be taken at baseline and at two months intervals for the first 6 months, then at yearly intervals for up to 5 years). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2021.
