About the EPPIK Study

The EPPIK Study is a Phase 2 clinical research study evaluating the safety and effectiveness of an investigational drug called sparsentan for the treatment of children with rare kidney diseases. The study is enrolling children from ages 1 to 17 who have been diagnosed with focal segmental glomerulosclerosis (FSGS), minimal change disease (MCD), immunoglobulin A Nephropathy (IgAN), Immunoglobulin A vasculitis (IgAV) or Alport syndrome (AS).

These rare kidney diseases are associated with progression to kidney failure and currently have limited treatment options. This study aims to understand if an investigational drug, sparsentan, can help the kidneys filter protein and slow the decline of kidney function. The amount of protein found in the urine (called proteinuria) is seen as a marker of kidney function. Lowering proteinuria levels is associated with better kidney health outcomes.

Studies on sparsentan in FSGS and IgA nephropathy have been ongoing since 2014 involving over 880 patients from the age of 8 years, providing information on the potential benefit and safety of sparsentan treatment. The EPPIK Study will measure the safety and tolerability of sparsentan and help us understand whether sparsentan can reduce proteinuria and slow the decline of kidney function in children from 1 year of age in a number of rare kidney diseases. Sparsentan has NOT been approved for the treatment of kidney disease.

The study will enroll about 57 participants globally. See the locations on the map below.

Who can participate in this study?

Children may be eligible who are 1 to 17 years old, and:

  • Have focal segmental glomerulosclerosis (FSGS) or minimal change disease (MCD), immunoglobulin A nephropathy (IgAN), Immunoglobulin A vasculitis (IgAV) or Alport syndrome (AS)
  • Are able to take a daily liquid medication by mouth
  • Are not on dialysis and have not had a transplant

Additional requirements will need to be met in order for your child to participate. The study doctor will review these requirements with you, or you may contact our medical team for more information.

What can participants expect?

Children who meet the eligibility criteria for enrollment in the study may expect to participate in the study for about 2 years and 3 months. Participants will take a daily dose of sparsentan in a liquid form, by mouth, and will have up to 18 study visits, including screening and study treatment visits, over the course of 108 weeks, or 27 months. During the first 3 months of study treatment, there will be 7 visits to your study doctor; the remaining 8 visits are scheduled three months apart.

Over the course of study treatment, your child will be monitored closely by the study medical team. These visits will evaluate the safety (whether sparsentan is harmful), tolerability (how you or your child feels taking sparsentan), effectiveness (how well sparsentan works) and how much sparsentan there is in your or your child’s blood (pharmacokinetics, also called PK). The study doctors will conduct blood tests, urine tests, skin tests (to check for swelling), and heart monitoring through an electrocardiogram (ECG) test.

As a participant in this study, you and your child have certain responsibilities, including:

  • Completing the visits to the study center
  • Taking the investigational drug as instructed by your study doctor
  • Informing the study doctor
    • if you notice any side effects and changes or new medical problems your child experiences during the study
    • if your child becomes pregnant
  • For female children who have started menstruation, taking birth control and a monthly pregnancy test

Like all medicines, the investigational drug can cause side effects, although not everybody gets them. Most side effects are mild to moderate.

About select proteinuric glomerular diseases

Focal Segmental Glomerulosclerosis (FSGS) – A condition in which scar tissue develops in the parts of the kidneys that filter waste products from the blood. FSGS has numerous causes and is a serious condition that may lead to kidney failure. Symptoms often present as those typical of nephrotic syndrome and can include:

  • Swelling in body parts like the legs, ankles and around the eyes
  • Weight gain due to extra fluid building in the body
  • Foamy urine caused by high protein levels in the urine
  • High cholesterol
  • Low levels of protein in the blood

Minimal Change Disease (MCD) – The condition that most commonly causes nephrotic syndrome in children. In this disorder, kidney damage can only be seen after a biopsy, where a sample of kidney tissue is taken and looked at under very powerful microscopes. Those with MCD experience the signs and symptoms of nephrotic syndrome much quicker than they would with other rare kidney diseases. Symptoms are almost identical to FSGS.

Immunoglobulin A Nephropathy (IgAN) – Also known as Berger’s disease. IgAN occurs when an antibody called immunoglobulin A (IgA) builds up in the kidneys. Over time this buildup hampers the kidneys' ability to filter waste from your blood. Symptoms can include:

  • Repeated episodes of cola- or tea-colored urine, and sometimes visible blood in the urine, usually during or after an upper respiratory infection and sometimes after strenuous exercise
  • Foamy urine from protein leaking into the urine
  • Pain in one or both sides of the back below your ribs
  • Swelling in the hands and feet
  • High blood pressure

Immunoglobulin A Vasculitis (IgAV), also known as Henoch-Schönlein Purpura (HSPN) - A disorder that causes the small blood vessels in the intestines, joints, skin, and kidneys to be inflamed and bleed. It is most common in children ages 2 to 6 and can cause serious kidney damage. Symptoms can include a purplish rash on the legs or buttocks or abdominal pain.

Alport Syndrome (AS) – A rare genetic disorder caused by an inherited defect in a structural material called type IV collagen. Type IV collagen is needed for the normal function of the ears, eyes and kidneys. Symptoms can include blood in the urine, hearing loss, and problems with eyesight.

What is a clinical research study?

A clinical research study, also called a clinical trial, studies human health and disease. These studies are conducted by doctors and researchers and depend on volunteers to collect data to determine if the investigational medication is safe and effective. The results of clinical studies help regulatory agencies like the U.S. Food and Drug Administration (FDA) or European Medicines Agency (EMA) decide if an investigational drug should be approved and made available to patients. Clinical studies are the only way we can develop new and better treatments and improve patient care. See our FAQs below for more answers.

Why is clinical research important?

Volunteers who participate in clinical research help doctors find better ways to provide care. As a study progresses, researchers gather more information about the disease and the investigational medication. The results of the study may show that the investigational medication improves patients' lives; it may also show no benefit. All results are important because they advance medical knowledge to treat the disease. These advances would not happen without the participation of volunteers.

Frequently asked questions

Travere Therapeutics is responsible for conducting this clinical study. Learn more about Travere Therapeutics at https://travere.com.

An investigational drug, also sometimes called an investigational medication or study drug, has not been approved for distribution to the general public. It is being studied to see if your disease or medical condition may be improved by taking the drug. In clinical trials, physician scientists work to determine if investigational medicines are safe and effective for treating medical conditions. They are also trying to determine the correct dosing, and the risks and benefits of taking the drug.

Participation in any clinical study is completely voluntary. Your decision to participate, or for your child to participate or not participate in this clinical study, will have no effect on the medical care that your child receives now or in the future. If you/your child is eligible and you choose to participate in the study, you may withdraw your child and leave the study at any time, and for any reason.

In most cases, people take part in clinical studies/trials to help others, contribute to science and/or try new therapies.

Every clinical research study must be reviewed, and is continually monitored, by a regulatory review committee to ensure the risks are as low as possible and are worth any potential benefits to the study participant. A regulatory review committee is a group of people who help protect the rights and welfare of people participating in research studies. These groups are known as Institutional Review Boards (IRB) or Ethics Committees (EC), depending upon your country and region. IRBs and ECs often include doctors, community leaders, and scientists. Your privacy is also protected. All research personnel follow strict local and national regulations to protect patients’ identifiable and health information. All information collected during the study will be kept confidential and your or your child’s name will not be listed in any reports or publications.

As a volunteer, you/your child have the right to discontinue participation and leave the study at any time and for any reason, with no penalty or loss of benefits to which you or your child are otherwise entitled.

Travere Therapeutics will reimburse all study participants for study-related travel and expenses as permitted by the IRB/EC in your/your child’s country. For more information, please speak with a member of the study team during your study visits.

All clinical research is conducted following a study protocol. A clinical study protocol is a written document that describes the study objectives, design, methods, assessment types, collection schedules, and statistical considerations for analyzing the data. The protocol also outlines steps for protecting participants and obtaining quality data. Before clinical research is started, the study protocol is reviewed and approved by national health agencies (e.g., U.S. Food and Drug Administration [FDA]) and other mandatory review bodies including Institutional Review Boards and Ethics Committees that focus on the welfare of clinical trial participants.

If you decide this clinical research study is appropriate for you or your child, the study doctor and staff will explain the investigational research study, then ask you to review an informed consent document. This document will describe the research, including its purpose, length, procedures, possible known risks and benefits of participating, and what is expected of you and your child if you take part. After you have reviewed this document, you can decide whether or not to sign the document and volunteer to participate in the study. If your child is old enough and able to understand the research study, the study doctor will review the study with your child and ask him or her to acknowledge their understanding by signing assent. Assent is different from consent as it is specially designed to indicate the minor understands the study and is willing to participate.
