Study Arms (2)

Treatment Sequence A (Fed) - B (Fasted)

EXPERIMENTAL

Subjects will receive a single 10 mg tablet of Nitisinone in treatment period 1 under fed conditions, and 10 mg tablet of Nitisinone in treatment period 2 under fasting conditions. Each treatment period will be separated by at least 23 calendar days of washout period.

Drug: Nitisinone

Treatment Sequence B (Fasted) - A (Fed)

EXPERIMENTAL

Subjects will receive a single 10 mg tablet of Nitisinone in treatment period 1 under fasting conditions, and 10 mg tablet of Nitisinone in treatment period 2 under fed conditions. Each treatment period will be separated by at least 23 calendar days of washout period.

Drug: Nitisinone

Interventions

Nitisinone DRUG

A single oral dose of Nitisinone 10 mg Tablet will be administered.

Treatment Sequence A (Fed) - B (Fasted); Treatment Sequence B (Fasted) - A (Fed)

Eligibility Criteria

• Age: 18 Years - 55 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)

You may qualify if:

• Healthy male and female subjects, 18 to 55 years (both inclusive) at signing of informed consent.
• Body Mass Index (BMI) between 18.5 and 30 kg/m2 (inclusive).
• Body mass not less than 50 kg.
• Medical history, vital signs, physical examination, standard 12-lead electrocardiogram (ECG) and laboratory investigations must be clinically acceptable or within laboratory reference ranges for the relevant laboratory tests, unless the investigator considers the deviation to be irrelevant for the purpose of the study.
• Non-smokers.
• Females, if:
• Of childbearing potential, the following conditions are to be met:
• Negative pregnancy test If this test is positive, the subject will be excluded from the study. In the rare circumstance that a pregnancy is discovered after the subject received IMP, every attempt must be made to follow her to term.
• Not lactating
• Abstaining from sexual activity (if this is the usual lifestyle of the subject) or must agree to use an accepted method of contraception, and agree to continue with the same method throughout the study Examples of reliable methods of contraception include non-hormonal intrauterine device, and barrier methods combined with an additional contraceptive method. In this study the concomitant use of hormonal contraceptives is NOT allowed. Other methods, if considered by the investigator as reliable, will be accepted.
• Written consent given for participation in the study.
• Subjects must be willing to consume the meal prescribed with administration of the IMP in full and within the required time.

You may not qualify if:

• Evidence of psychiatric disorder, antagonistic personality, poor motivation, emotional or intellectual problems likely to limit the validity of consent to participate in the study or limit the ability to comply with protocol requirements.
• Current alcohol use \> 21 units of alcohol per week for males and \> 14 units of alcohol per week for females.
• Consumption of more than 5 cups of coffee (or equivalent amounts of caffeine) per day.
• Regular exposure to substances of abuse (other than alcohol) within the past year.
• Use of any medication, prescribed or over-the-counter or herbal remedies, within 2 weeks before the first administration of investigational medicinal product (IMP) except if this will not affect the outcome of the study in the opinion of the investigator.
• In this study the concomitant use of hormonal contraceptives is NOT allowed.
• Participation in another study with an experimental drug, where the last administration of the previous IMP was within 8 weeks (or within 10 elimination half-lives for chemical entities or 2 elimination half-lives for antibodies or insulin), whichever is the longer) before administration of IMP in this study, at the discretion of the investigator.
• Treatment within the previous 3 months before the first administration of IMP with any drug with a well-defined potential for adversely affecting a major organ or system.
• A major illness during the 3 months before commencement of the screening period.
• History of hypersensitivity or allergy to the IMP or its excipients or any related medication.
• History of bronchial asthma or any other bronchospastic disease.
• History of convulsions.
• History of porphyria.
• Relevant history or laboratory or clinical findings indicative of acute or chronic disease, likely to influence study outcome.
• Donation or loss of blood equal to or exceeding 500 mL during the 8 weeks before the first administration of IMP.
