Confirmatory Study of Govorestat in CMT-SORD

Withdrawn before enrolling · Phase 3 · Has a placebo group

Conditions studied: Charcot-Marie-Tooth Disease With Sorbitol Dehydrogenase Deficiency (CMT-SORD)

In brief

This study is designed to assess the long-term efficacy and clinical benefit of AT-007 in patients with CMT-SORD. This randomized, double-blind study will assess the effect of govorestat compared to placebo in patients with CMT-SORD for up to 36 months.

Who can join

Age: 16 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Willing and able to provide signed and dated informed consent prior to any study-related procedures and willing and able to comply with all study procedures.
• Male and non-pregnant, non-lactating female patients between the ages of 16 and 65 years, inclusive.
• Females must be of non-childbearing potential (defined as surgically sterile [i.e., had a bilateral tubal ligation, hysterectomy, or bilateral oophorectomy ≥6 months prior to the first dose of study drug] or postmenopausal for ≥1 year [confirmatory follicle stimulating hormone or FSH test results required] prior to the first dose of study drug) or agree to use a highly effective form of birth control from Screening until 30 days after the last dose of study drug.
• Males must be unable to procreate (defined as surgically sterile [i.e., had a vasectomy ≥6 months prior to Screening]) or must agree to use a highly effective form of birth control from Screening through 105 days (sum of 5 half-lives and 90 days interval as per CTFG guidelines) after the last dose of study drug.
• Clinical diagnosis of Charcot-Marie-Tooth Type 2 (CMT2) or distal Hereditary Motor Neuropathy (dHMN) due to CMT-SORD confirmed by medical record or written communication by health care professional, elevated blood sorbitol level (>10,000 ng/mL), and SORD gene analysis report indicating at least one pathogenic mutation.
• Patient may be on concomitant medications and dietary supplements; however, they must be on stable doses for at least 1 month prior to Screening and throughout the study. In addition, all over-the-counter (OTC) and/or prescription medications must be reviewed and approved by the Investigator.

You may not qualify if…

• Absence of force generated in one or both feet with dorsiflexion (value of 0 Newton).
• History or presence of clinically significant hematopoietic, renal, hepatic, endocrine (e.g. diabetes), metabolic, pulmonary, neurological (e.g. other neuropathy, myopathy or neuromuscular disorder), psychiatric, cardiovascular, immunological, dermatological, or gastrointestinal diseases that are - a priori - altering the proper evaluation of the safety and efficacy of govorestat; conditions capable of altering the absorption, metabolism, or elimination of drugs; or conditions that constitute a risk factor when taking the study drug and/or impact the conduct or results of the study.
• Body Mass Index (BMI) >35 kg/m2.
• Clinically relevant underweight, weight loss suggestive of a pathology unrelated to CMT-SORD, or BMI < 17.5 kg/m2.
• Positive test for hepatitis B surface antigen, hepatitis C antibody, or human immunodeficiency virus (HIV) at Screening or previous treatment for hepatitis B, hepatitis C, or HIV infection.
• Individuals who smoke or use tobacco or nicotine-containing products.
• Pregnant, lactating, or not using/not willing to use appropriate means of contraception.
• Any prior history of substance abuse (including alcohol) or treatment for such.
• Positive urine drug screen (UDS) for drugs of abuse (amphetamines, barbiturates, benzodiazepines, cocaine, opiates) or cotinine.
• Non-ambulatory disability.
• Lower limb surgery such as bilateral ankle stabilization or contracture release in the past 5 years.
• Impaired renal function or estimated glomerular filtration rate (eGFR) less than 90 mL/min/1.73 m2. Note: The eGFR is an estimation of renal function, and the ultimate decision of whether a patient has normal renal function (and can be included in the study) is at the discretion of the Investigator, assuming there are no safety concerns. Also, because eGFR can vary from day to day based on outside factors, patients can be re screened for eGFR multiple times to understand the renal function of the patient.
• Hemoglobin (Hgb) < 10.0 g/dL at Screening.
• Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) or total bilirubin (except in case of Gilbert's syndrome) > 1.5 x upper limit of normal (ULN) at Screening.
• Urinary albumin-to-creatinine ratio (UACR) > 30 mg/g at Screening in the presence of elevated creatinine (>2X ULN).
• History or presence of cardiovascular disorders including myocardial infarction, stroke, uncontrolled hypertension (sitting blood pressure ≥140/90 mmHg), left ventricular (LV) hypertrophy, atrial fibrillation, or valvular heart disease considered clinically significant by the Investigator and/or Sponsor medical representative.
• Abnormal findings on the Screening 12-lead ECG, such as ST/T wave changes, pathological Q wave changes, or any rhythm other than normal sinus rhythm considered clinically significant by the Investigator and/or Sponsor medical representative.
• Evidence of significant active hematological disease and/or cumulative blood donation of 1 unit (500 mL) or more including blood drawn during clinical studies in the last 3 months.
• History of significant drug allergy or drug hypersensitivity.
• Investigators, site personnel directly affiliated with this study, and their immediate families (defined as a spouse, parent, child, or sibling, whether biological or legally adopted).
• Any other condition that, in the opinion of the Investigator, precludes the patient from following and completing the protocol.
• A clinically significant abnormal finding on the physical exam, medical history or clinical laboratory results at Screening.
• A significantly abnormal diet (per Investigator judgment) during the 4 weeks preceding the first dose of study drug.
• Participation in another clinical study of a different investigational product within 30 days prior to the first dose of study drug.
• Use of any OTC medication (including nutritional or dietary supplements, herbal preparations, or vitamins) ≤7 days prior to the first dose of study drug until the last dose of study drug without evaluation and approval by the Investigator.
