Primary Purpose: Treatment
||A Phase 1, Randomized, Double-Blinded, Placebo-Controlled, Third Party Open, Multiple Dose Escalation, Single Center Study to Evaluate the Safety, Tolerability and Pharmacokinetics of Subcutaneously Administered ELX-02 in Independent Consecutive Cohorts of Healthy Subjects
Primary Outcome Measures:
| Estimated Enrollment:
| Actual Study Start Date:
||October 11, 2017
| Estimated Study Completion Date:
||November 30, 2018
| Estimated Primary Completion Date:
||June 30, 2018 (Final data collection date for primary outcome measure)
Placebo Comparator: Placebo Comparator Arm
This is a study in humans of ELX-02, an advanced synthetic aminoglycoside optimized as a translational read-through drug (TRID) for the treatment of genetic conditions caused by nonsense mutations. This is a classical Phase 1b study designed as a randomized, double-blinded, placebo-controlled, multiple dose escalation to evaluate the safety, tolerability, and pharmacokinetics of ELX-02 in healthy adult volunteers.

|Ages Eligible for Study:
||18 Years to 55 Years (Adult)
|Sexes Eligible for Study:
|Accepts Healthy Volunteers:
Inclusion criteria: Subjects must meet all of the following inclusion criteria to be eligible for enrollment into the study:
- Be able and willing to provide written Informed Consent indicating that the subject has been informed of all pertinent aspects of the study.
Healthy female subjects and male subjects who, at the time of screening, are between the ages of 18 and 55 years, inclusive.
Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure (BP) and pulse rate measurement, 12-lead electrocardiogram (ECG), and clinical laboratory tests.
Female subjects of non-childbearing potential must meet at least one of the following criteria:
- Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; post-menopausal status will be confirmed by a serum follicle-stimulating hormone level;
- Have undergone a documented hysterectomy and/or bilateral oophorectomy;
- Have medically confirmed ovarian failure. All other female subjects (including females with tubal ligations) will be considered to be of childbearing potential and may be enrolled if they have negative pregnancy tests at screening and admission day and agree to use a highly effective method of contraception for 14 days before first study drug administration and 28 days after last study drug administration. Female subjects of childbearing potential must agree to undergo repeated pregnancy tests.
- Male subjects must be willing to use an effective method of contraception. They must agree to use a condom consistently and correctly, during the course of the study until 28 days after last study drug administration.
- Not using any prescription medication and dietary supplements within 30 days or 5 half lives (whichever is longer) prior to the first study drug administration, except for contraceptives - nor be taking any over-the-counter (OTC) herbal or medicinal products. As an exception, acetaminophen/paracetamol may be used at doses of ≤2 g/day.
- Non-smoking and no use of any tobacco or nicotine products (by declaration) for a period of at least 6 months prior to screening visit.
- Be on no medication with potential to impair renal function (e.g., non steroidal anti inflammatory [NSAID]s) or with ototoxic potential (e.g., quinine, salicylates, aminoglycosides).
- Normal renal function (glomular filtration rate >60 mL/min) based on creatinine plasma concentration and the Modification of Diet in Renal Disease (MDRD) equation for estimated glomular filtration rate. Subjects with lower MDRD clearance can be included on the condition that they have a normal 24h creatinine clearance (determined by a 24h urine collection).
- Negative human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) serology tests at screening.
- No history of alcohol or DOA. Negative urine test for DOA and alcohol breath test at screening and Day -1.
- No personal history (or current) or hereditary hearing loss, persistent tinnitus, persistent vertigo, persistent imbalance and persistent unsteadiness.
- Body Mass Index (BMI) of 19.0 to 30.0 kg/m2 (inclusive); and a total body weight >50.0 kg (110 lbs) and <100.0 kg.
Exclusion criteria: Subjects with any of the following characteristics/conditions will not be included in the study:
- Subjects who are investigational site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the Investigator, or subjects who are the Sponsor employees directly involved in the conduct of the study.
- Concurrent participation or participation in another clinical trial within at least 5 tissue half-lives prior to dosing (calculated from the previous study's last dosing day). If the previous trial involved agents with delayed effects or prolonged metabolism, a 12 months interval is required.
- Evidence or history of clinically relevant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (including drug allergies). This includes any acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational drug administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study.
- Presence of mitochondrial mutations making subject susceptible to aminoglycoside toxicity (A1555G, C1494T, T1095C, A827G, 1-BP DEL, 961T, C INS).
- Subjects with any history of ear disease or surgeries, persistent dizziness or persistent tinnitus.
Subjects with any abnormality at screening, that indicates the presence of a vestibular pathology, conductive hearing loss or balance problem (by an ENT).
Subjects with abnormalities in audiometry results at screening as follows: any pure-tone threshold >55 dB and/or inter-ear difference in any frequency of >20 dB.
Dizziness Handicap Inventory (DHI)-H score>16. Tinnitus Handicap Inventory (THI)-H score >14.
- History of regular alcohol consumption exceeding 14 drinks/week for females or 21 drinks/week for males (1 drink = 150 mL of wine or 360 mL of beer or 45 mL of hard liquor) within 6 months of screening.
- Screening supine BP ≥ 140 mm Hg (systolic) or ≥ 90 mm Hg (diastolic), following at least 5 min of supine rest. If BP is ≥ 140 mm Hg (systolic) or ≥ 90 mm Hg (diastolic), the BP should be repeated two more times and the average of the three BP values should be used to determine the subject's eligibility.
- Screening supine 12-lead ECG demonstrating QTc >450 msec for men and >470 msec for women, or a QRS interval >120 msec. If QTc or QRS exceed these limits, the ECG should be repeated two more times and the average of the three QTc or QRS values should be used to determine the subject's eligibility.
- Subjects with ANY abnormalities in clinical laboratory tests at screening, considered by the study physician as clinically relevant. In particular, subjects with alanine aminotransferase (ALT), aspartate aminotransferase (AST), serum creatinine and total bilirubin ≥ 1.5 upper limit of normal will be excluded.
- Pregnant or breastfeeding female subjects.
- Subjects who donated blood or received blood or plasma derivatives in the three months preceding study drug administration.
- Unwilling or unable to comply with all scheduled visits, treatment plan, laboratory tests and other study procedures and the restrictions described in this protocol.
- Known relevant allergy to any drug and/or aminoglycosides.
- Subjects with an inability to communicate well with the Investigators and CPU staff (e.g., language problem, poor mental development).
- Subjects with visual impairment or inability to read and comprehend the DHI and THI scales.
- Subjects with any acute medical situation (e.g., acute infection) within 48 hours of study start, which is considered of significance by the Investigator.
