Study summary

This is an open-label, multi-centre study in subjects with a genetically confirmed mitochondrial deoxyribonucleic acid (DNA) transfer ribonucleic acid (tRNA)Leu(UUR) m.3243A>G mutation who completed study KH176-202. In the KH176-203 study subjects will be receiving KH176 100 mg BID or KH176 50 mg bid in die (BID) (as determined by the investigator based on safety / tolerability considerations) for a year, thereby ensuring continued treatment with KH176 after study KH176-202. A final follow-up visit is scheduled 4 weeks after the intake of the last dose of study medication for patients not rolling over into the compassionate use program. Primary safety data and secondary efficacy (endpoint) data will be monitored and reviewed every three months by an independent Data Safety Monitoring Board (DSMB) to evaluate potential risks and benefits.

Read the detailed description

Mitochondrial diseases, estimated prevalence 1 in 4,300 adults, are caused by pathogenic mutations in genes that ultimately encode mitochondrial proteins of the different enzyme complexes of the oxidative phosphorylation system (OXPHOS). Of these mutations, the 3243> G nucleotide change in the mitochondrially encoded transfer RNALeu (UUR) leucine 1 gene (MT TL 1) is the most prevalent one. When mitochondria are defective, it can result in a wide variety of serious and debilitating diseases, especially in energy-demanding tissues such as the muscles and brain. Therefore, signs and symptoms of mitochondrial disease can include a variety of symptoms such as fatigue, exercise tolerance, muscle weakness, and ataxia, heart failure, deafness, blindness, stunted growth, and cognitive learning disabilities.

Despite advances in understanding mitochondrial disease, treatment options are extremely limited and largely supportive to date. Therefore, there is an urgent need for new treatments. KH176, a pharmaceutical ingredient (API), is an orally bioavailable small molecule under development for the treatment of these conditions. KH176 acts as a potent intracellular redox modulating agent targeting the reactive oxygen species as demonstrated in a number of in vitro and in vivo assays. An earlier phase II study showed positive effects of KH176 on alertness and mood.

The main objective of the current study is to enable continued treatment with KH176-202 for patients who have completed the KH176-202 study. Since KH176 is expected to be a chronic treatment for mitochondrial diseases, this study will examine long-term safety and explore long-term efficacy. To this end, the highest dose of 100 mg KH176 twice daily (safe and well tolerated by the target group in study KH176-201) will be used as the initial dose, to be administered over 1 year (minimum 365 days). Study KH176-202 uses doses of 50 mg twice daily and 100 mg twice daily. Currently, this study is still blinded, but a review of blinded safety data suggests that these doses are well tolerated.

Primary safety data and secondary efficacy (endpoint) data will be monitored and reviewed every three months by an independent Data Safety Monitoring Board (DSMB) to evaluate potential risks and benefits.

Inclusion criteria

  1. Males and females aged 18 years or older at screening.
  2. Ability and willingness to provide written prior to screening evaluations.
  3. Having fulfilled all inclusion and exclusion criteria and completed the full treatment period of study KH176-202.
  4. Disease appropriate physical and mental health as established at Screening by medical history, physical examination, and vital signs recording, and results of clinical chemistry and haematology testing as judged by the investigator.
  5. Objectified (LVEF) ≥45% (echocardiography, or otherwise).
  6. Left Ventricular (LV) wall thickness ≤15 mm.
  7. Left atrium dilatation ≤ 40 mL/m2. Note: No need to test LV parameters (criteria #5, #6, #7) if favourable echocardiography (or otherwise) results dated less than 13 months prior to Screening are available.
  8. Women of must be willing to use highly effective methods during the entire study, i.e., combined (estrogen and progestogen containing) oral, intravaginal or transdermal hormonal contraception associated with inhibition of ovulation;, oral, injectable or implantable progestogen-only hormonal contraception associated with inhibition of ovulation; use of an intrauterine device; an intrauterine hormone releasing system, bilateral tubal occlusion and vasectomy of the partner. Any hormonal contraception method must be supplemented with a barrier method (preferably male condom). Vasectomised partner is considered a highly effective birth control method provided that partner is the sole sexual partner of the subject and that the vasectomised partner has received medical assessment of the surgical success. Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. Reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

    Note 1: Natural family planning methods, female condom, cervical cap or diaphragm are not considered adequate contraceptive methods in the context of this study.

    Note 2: To be considered not of childbearing potential, potential female subjects must be for at least two years, or have been surgically sterilised (bilateral tubal ligation, hysterectomy or bilateral oophorectomy) for at least 6 months prior to Screening.

    Note 3: KH176 has been shown non-genotoxic judged from the Ames test, Chromosomal Aberration test and in vivo Micronucleus test. Moreover, appreciable systemic exposure from the exposure to (\~2.5 mL) semen is extremely unlikely. However, until reproductive toxicology studies have confirmed that KH176 does not adversely affect normal reproduction in adult males and females, as well as causing developmental toxicity in the offspring, the following contraceptive precautions must be adhered to:

    • male subjects with female partners of childbearing potential must be willing to use condoms during the entire study.
    • female partners of childbearing potential of male subjects must be willing to use adequate contraceptive methods during the entire study, i.e., a hormonal contraceptive method (pill, vaginal ring, patch, implant, injectable, hormone-medicated intrauterine device) or an intrauterine device.
  9. Able to comply with the study requirements, including swallowing study medication.

Exclusion criteria

Exclusion criteria:

In order to be eligible to participate in this study, a subject must not meet any of the following criteria:

  1. Surgery of gastro-intestinal tract that might interfere with absorption.

  3. Documented history of ventricular tachycardia (HR>110 beats/min), PVC burden ≥5% or daytime Mobitz II AV block on any of the Holter assessments in the KH176-202 study or in the medical history.
  4. History of acute heart failure, (family) history of unexplained syncope or congenital long and short syndrome or sudden death.
  5. abnormal laboratory, vital signs or physical or mental health; e) (ASAT) or alanine aminotransferase (ALAT) > 3 x (ULN), or > 3 x ULN at screening. If a patient has ASAT or ALAT > 3 x ULN but \< 3.5 x ULN, re-assessment is allowed at the investigator's discretion.

    f) Estimated ≤ 60 mL/min according to the CKD-EPI formula at screening.

    g) Systolic blood pressure > 150 mmHg at screening or baseline. h) All other clinically relevant parameters at screening or baseline as judged by the Investigator.

  7. Serum hyperkalemia (> 5.0 mEq/L).
  8. Serum hypokalemia (\< 3.5 mEq/L).
  9. History of ischemic heart disease.
  10. Symptomatic heart failure.
  11. Clinically relevant aorta and/or mitralis valvular defect as judged by the investigator.
  12. Pregnancy or breast feeding (females).
  13. History of or idiosyncrasy to any of the components of the investigational drug.
  14. Medical history of drug abuse (illegal drugs such as cannabinoids, amphetamines, cocaine, opiates or problematic use of prescription drugs such as benzodiazepines, opiates).
  15. The use of any of the following medication and/or supplements within 4 weeks or 5 times the half-life (whichever is longer) prior to the first dosing of the study medication:

    1. (multi)vitamins, co-enzyme Q10, Vitamin E, riboflavin, and antioxidant supplements (including, but not limited to idebenone/EPI-743, mitoQ or alternative names for similar products); unless stable for at least one month before first dosing and remaining stable throughout the study.
    2. any medication negatively influencing mitochondrial functioning (including but not limited to valproic acid, glitazones, statins, anti-virals, amiodarone, and non-steroidal anti-inflammatory drugs (NSAIDs)), unless stable for at least one month before first dosing and remaining stable throughout the study.

      Note: thus, mitoQ and any medication negatively influencing mitochondrial functioning are allowed as long as the dose has been stable for at least one month prior to first dosing and remains stable throughout the study.

    3. any strong Cytochrome P450 (CYP)3A4 inhibitors (all 'conazoles-anti-fungals', antivirals, grapefruit).

    5. any medication known to affect cardiac repolarisation, unless QTc interval at screening is normal during stable treatment for a period of two weeks, or 5 half-lives of the medication and its major metabolite(s), whichever period is the shortest (all anti-psychotics, several anti-depressants, e.g. nor-/amytriptiline, fluoxetine, anti-emetics: domperidone, granisetron, ondansetron). For a complete list see https://crediblemeds.org.
    6. any medication metabolised by CYP3A4 with a narrow therapeutic width
Terms in these criteria, in plain language(16)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
