Eligibility Criteria
Inclusion
- All subjects must satisfy the following criteria to be considered for study participation:
- Subject must be a male or non-pregnant, non-breastfeeding female.
- Subject must be between 18 and 50 years of age (inclusive).
- Subject's Body Mass Index (BMI) must be between 18 and 30 kg/m2 (inclusive), and subject must weigh a minimum of 50 kg (110 lbs).
- Female subjects must agree to use one of the following forms of birth control from screening until 14 days after completion of the study:
- Vasectomized partner (at least 6 months prior to dosing)
- Post-menopausal (at least 2 years prior to dosing)
- Surgically sterile (bilateral tubal ligation, hysterectomy, bilateral oophorectomy) at least 6 months prior to dosing
- Double barrier (diaphragm with spermicide; condoms with spermicide)
- IUD (intrauterine device)
- Abstinence (must agree to use a double barrier method if they become sexually active during the study)
- Implanted or intrauterine hormonal contraceptives in use for at least 6 consecutive months prior to study dosing and throughout the study duration
- Oral, patch, and injected contraceptives or vaginal hormonal device (i.e. NuvaRing®) in use for at least 3 consecutive months prior to study dosing and throughout the study duration.
- Subject must voluntarily consent to participate in this study and provide their written informed consent prior to start of any study-specific procedures.
- Subject is willing and able to remain in the study unit for the entire duration of each confinement period.
- Subject is willing and able to consume the entire high-calorie, high-fat breakfast meal in the designated timeframe required during the assigned study period.
- Subject's vital signs must be within the following ranges to be included: Vital signs measured sitting after 3 minutes rest; heart rate: 40-90 bpm; systolic BP: 110-140 mmHg; diastolic BP: 60-90 mmHg. Out-of-range vital signs may be repeated once. Predose vital signs will be assessed by the Principal Investigator or designee (e.g., a medically qualified sub-investigator) prior to study drug administration. The Principal Investigator or designee will verify the eligibility of each subject with out-of-range vital signs and document approval prior to dosing.
Exclusion
- History or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic, oncologic, or psychiatric disease or any other condition that, in the opinion of the Investigator, would jeopardize the safety of the subject or the validity of the study results.
- Has a clinically significant abnormal finding on the physical exam, medical history, electrocardiogram (ECG), or clinical laboratory results at screening.
- History of any syncopal episode or seizures.
- Presence of acute disease state (eg, nausea, vomiting, fever, diarrhea) within 7 days prior to scheduled dose administration.
- History or presence of allergic or adverse response to lofexidine or related drugs.
- Has been on a significantly abnormal diet during the 4 weeks preceding the first dose of study medication.
- Has donated blood or plasma within 30 days prior to the first dose of study medication.
- Has participated in another clinical trial (randomized subjects only) within 30 days prior to the first dose of study medication.
- Has used any over-the-counter (OTC) medication, including nutritional supplements, within 7 days prior to the first dose of study medication.
- Has used any prescription medication, except hormonal contraceptive or hormonal replacement therapy, within 14 days prior to the first dose of study medication.
- Subjects that have discontinued the use of implanted, intrauterine, or injected hormonal contraceptives must not have used any for 6 months prior to the first dose of study medication.
- Subjects that have discontinued the use of oral, patch, or vaginal hormonal contraceptives must not have used any for 1 month prior to the first dose of study medication.
- Has been treated with any known drugs that are moderate or strong inhibitors/inducers of CYP enzymes such as barbiturates, phenothiazines, cimetidine, carbamazepine, etc., within 30 days prior to the first dose of study medication and that in the Investigator's judgment may impact subject safety or the validity of the study results.
- Has smoked or used tobacco products within 60 days prior to the first dose of study medication.
- Has any prior history of substance abuse or treatment (including alcohol) within the past 2 years.
- Is a female with a positive pregnancy test result.
- Has a positive urine screen for drugs of abuse (amphetamines, barbiturates, benzodiazepines, cocaine, cannabinoids, opiates).
- Has a positive test for Hepatitis B surface antigen, Hepatitis C antibody, or Human Immunodeficiency Virus (HIV) at screening or has been previously treated for Hepatitis B, Hepatitis C, or HIV infection.
- Has orthostatic hypotension at screening defined as a drop in systolic blood pressure ≥ 20 mmHg or a fall in diastolic blood pressure ≥ 10 mmHg following a 2 minute stand. Out-of-range vital signs may be repeated once. Predose vital signs will be assessed by the Principal Investigator or designee (e.g., a medically qualified sub-investigator) prior to study drug administration. The Principal Investigator or designee will verify the eligibility of each subject with out-of-range vital signs and document approval prior to dosing.
- Subjects with a QTcF greater than 450 msec (males) or greater than 470 msec (females), at screening obtained after 10 minutes rest in a supine position using the ECG machine algorithm.
