This is an interventional basic science trial for Inner Ear Diseases focused on measuring Pharmacokinetics, Healthy Volunteer Study Read More

Inclusion Criteria:

1. Healthy Caucasian males and females (non-pregnant/non-lactating) between 18 and 50 years of age.
2. Female subject of child bearing potential with a negative pregnancy test at the screening visit and willing to use 2 effective methods of contraception, from first dose until 3 months afterwards (i.e., until 3 months after taking IMP).

3. Female subject of non-child bearing potential with with negative pregnancy test at the screening visit.

   For the purposes of this study, this is defined as the subject being amenorrheic for at least 12 consecutive months or at least 4 months post-surgical sterilisation (including bilateral fallopian tube ligation or bilateral oophorectomy with or without hysterectomy) and levels of follicle stimulating hormone (FSH) falling within the respective pathology reference range. In the event a subject's menopause status has been clearly established (for example, the subject indicates she has been amenorrheic for 10 years), but FSH levels are not consistent with a post-menopausal condition, determination of subject eligibility will be at the discretion of the Investigator following consultation with the Sponsor's Responsible Physician.

4. Male subject willing to use 2 effective methods of contraception, (unless anatomically sterile) from first dose until 3 months afterwards (i.e., until 3 months after taking IMP).
5. Subject with a body mass index (BMI) of 18-30 kg/m2. BMI = body weight (kg)/height (m)2.
6. Subject with no clinically significant abnormal serum biochemistry, haematology and urine examination values within 14 days of the first dose.
7. Subject with a negative urinary drugs of abuse screen, determined within 14 days of the first dose (a positive alcohol result may be repeated at the discretion of the Investigator).
8. Subject with negative human immunodeficiency virus (HIV), hepatitis B surface antigen (Hep B) and hepatitis C virus antibody (Hep C) results.
9. Subject with no clinically significant abnormalities in 12-lead electrocardiogram (ECG) determined within 14 days of the first dose.
10. Subject with no clinically significant abnormalities in blood pressure or pulse determined within 14 days of the first dose.
11. Subject is a non-smoker or ex-smoker who has not smoked in the last 3 months (determined by urine cotinine < 500 ng/mL at screening visit).
12. Subject is available to complete the study (including all follow-up visits) and comply with study restrictions.
13. Subject satisfies a medical examiner about their fitness to participate in the study.
14. Subject provides written informed consent to participate in the study.

Exclusion Criteria:

1. Subject with a clinically significant history of gastrointestinal disorder likely to influence drug absorption.
2. Subject in receipt of regular medication (with the exception of contraception) within 14 days of the first dose that may have an impact on the safety and objectives of the study (Investigator's discretion).
3. Subject with evidence of renal, hepatic, central nervous system, respiratory, cardiovascular or metabolic dysfunction.
4. Subjects with any renal (serum creatinine (CREAT) level > 1.5 fold above the upper limit of normal (ULN)) or liver insufficiency (alkaline phosphatase (ALP) level > 1.2 fold above ULN, gamma glutamyl transferase (GGT), aspartate transaminase (AST), or alanine transaminase (ALT) level > 2.5 fold above ULN, and total bilirubin (BIL-T) level > 1.5 fold above ULN).
5. Subject with history of, or family history (immediate relative) of, long QT syndrome or Torsade de Pointes or symptomatic bradycardia.
6. Subject with clinically significant history of previous allergy / sensitivity to SENS-218 or its excipients or other 5-hydroxytryptophan3 (5-HT3) receptor antagonists.
7. Subject with a clinically significant history of drug or alcohol abuse.
8. Subject with inability to communicate well with the Investigator (i.e., language problem, poor mental development or impaired cerebral function).
9. Subject participation in a New Chemical Entity clinical study within the previous 4 months or a marketed drug clinical study within the previous 3 months. (N.B. washout period between studies is defined as the period of time elapsed between the last dose of the previous study and the first dose of the next study).
10. Subject donated 450 mL or more blood within the previous 3 months
