1.Healthy males and females between 18 and 55 years of age, inclusive, at Screening.
2.Body mass index (BMI) between 18 and 32 kg/m2 (inclusive) and weighs at least 50 kg at Screening.
3.Healthy in the opinion of the Investigator, based upon medical history, physical examination (including 12-lead ECG, and clinical laboratory assessments without any clinically significant findings, as deemed by the Investigator) at Screening and prior to dosing on admission or pre dose as applicable.
4. Female participants must be non-lactating and of non-child-bearing potential (i.e., surgically sterilized by hysterectomy, bilateral salpingectomy, or bilateral oophorectomy at least 6 weeks before Screening) or postmenopausal (defined as no menses for 12 months without an alternative medical cause and a follicle stimulating hormone [FSH] result per local laboratory guidelines; luteinizing hormone [LH] testing may be done if FSH results are inconclusive), or, if of child-bearing potential:
a. Must have a negative pregnancy test at Screening and a negative pregnancy test on
Day -1, prior to dose administration.
b. Must agree not to donate ova or attempt to become pregnant from the time of signing
consent until at least 90 days after the last dose of radiprodil.
c. If not exclusively in a same-sex relationship, must agree to use adequate contraception
(which is defined as use of a condom by the male partner combined with use of a highly
effective method of contraception) from one month prior to Screening until at least 90 days after the last dose of radiprodil.
5. Male participants, if not surgically sterilized, must:
a. Agree not to donate sperm from the time of signing consent until at least 90 days after
the last dose of IP.
b. If engaging in sexual intercourse with a female partner who could become pregnant,
must agree to use adequate contraception (defined as use of a condom plus a highly
effective method of contraception) from the time of signing consent until at least 90 days after the last dose of IP.
c.If engaging in sexual intercourse with a female partner who is not of child-bearing potential or a same-sex partner, must agree to use a condom from the time of signing consent until at least 90 days after the last dose of IP
6.Ability to provide signed informed consent and to understand and comply with the requirements of the study including dietary requirements and requirement to stay confined on site for the duration of the study.
1.History of hypersensitivity to radiprodil or any components of the formulations.
2.History of any medical condition that, in the opinion of the Investigator, would pose an additional risk to the participant by their participation in the study.
3.Females who are pregnant, breastfeeding, or have a positive pregnancy test at Screening or on Study Day -1.
4.History or presence of significant (in the opinion of the Investigator) cardiovascular, pulmonary, hepatic, renal, haematological, gastrointestinal, endocrine, immunologic, dermatologic, urologic, neurological, malignancy, psychiatric disease, or brain surgery or injury.
5.Any surgical or medical condition that, in the opinion of the Investigator, could interfere with the absorption, distribution, metabolism, or excretion of the drug.
6.History of any clinically significant allergic conditions (including drug allergies, asthma, eczema, or anaphylactic reactions, but excluding untreated, asymptomatic seasonal allergies at time of dosing on Day 1).
7.History of illicit drug abuse or alcohol abuse use within 2 years of Screening.
8.History of suicide attempts or deliberate self-harm, or a score of 4 or 5 on ideation or any suicidal behaviour on the Columbia-Suicide Severity Rating Scale (C-SSRS).
9.Routine consumption of more than 2 units of alcoholic beverages per day or more than 14 units per week (A unit of alcohol is equivalent to 1 can of beer, 1 glass of wine, or the equivalent of 1 alcoholic drink).
10.Routine consumption of an average of more than five (5) 240 mL servings of coffee or other caffeinated beverages per day.

13.Use of tobacco-containing products and nicotine or nicotine containing products in the 2 months prior to Day 1.
14.Use of any investigational product and prescription drug (with the exception of birth control medication) within 30 days of Day -1 or within 5 half lives whichever is longer.
15.Use of any over-the-counter (OTC) medication including herbal products (e.g., St John’s wort) within the 14 days or 5 half-lives prior to dosing, whichever is longer, and through the completion of all study procedures. Up to 2 grams per day of acetaminophen will be allowed at the discretion of the Investigator.

23.Any clinically significant ECG abnormality at Screening (as deemed by the Investigator).
24.QTcF interval > 450 msec for male and >470 msec for female (the average value for the triplicate ECG at Screening and Day -1), or history of prolonged QT syndrome.
