Show details

- Male or female subjects 18 to 55 years of age, inclusive.

- Subjects had to be opioid users who were not currently physically dependent on
opioids (based on DSM-IV criteria) but had experience in the use of opioids for
non-therapeutic purposes (i.e. for psychoactive effects) on at least 10 occasions
within last year and at least once in the 12 weeks prior to the screening session.

- Subjects had to be healthy as indicated by medical history, physical examination,
vital signs, oxygen saturation, clinical laboratory tests, and 12-lead ECG performed
at the screening session.

- Subjects had to consent to use two medically acceptable methods of contraception
throughout the entire study period, including washout periods, and for females until
one week after the study was completed.

- Female subjects had to have a negative serum pregnancy test at screening and a
negative urine pregnancy test prior to the qualifying session and each treatment
session, and not be lactating.

- Subject was willing and able to remain in the study unit for the entire duration of
each confinement period and return to the study site for any outpatient visits.

- Subjects with a positive urine drug screen for opiates, amphetamines, cocaine and
benzodiazepines at screening could enroll, provided they tested negative for the
substances at the qualifying and each treatment session and had no clinically
observed signs or symptoms of drug withdrawal.

- Subjects with a positive urine screen of tetrahydrocannabinol (THC) at screening
could be enrolled, provided the THC levels were stable or decreasing on subsequent
drug screens (prior to the qualifying and each treatment session).

- Subjects with body mass index (BMI) within the range 21-31 kg/m2 and weight greater
than 55 kg, inclusive.

- Subjects had to voluntarily consent to participate in this study, provide their
written informed consent prior to commencement of any study-specific procedures and
understand that they were free to withdraw from the study at any time.

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details

Subjects excluded from the study were those:

- With a history or presence of clinically significant cardiovascular, pulmonary,
hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic,
neurologic, oncologic or psychiatric disease or any other condition, which, in the
opinion of the investigator, would jeopardize the safety of the subject or the
validity of the study results.

- With a history of clinically significant brain conditions (e.g., neoplasms,
cerebrovascular disease, history of stroke, syncope, infectious disease or
significant head trauma) or currently were being treated with medications or
treatment regimens that lower seizure threshold.

- With a history or presence of drug or alcohol dependence excluding nicotine and
caffeine. This included subjects who had ever been in a drug rehabilitation program.

- Who had a current psychiatric illness, except nicotine dependence. Subjects with a
past history of psychiatric illness could be excluded at the discretion of the
Investigator or designee.

- Who had a history of chronic obstructive pulmonary disease or any other lung disease
(e.g., asthma) that could cause CO2 retention.

- Who had a clinically significant abnormal finding on the physical exam, medical
history or clinical laboratory results at screening.

- Who had a history of allergic or adverse response to the study drugs or related
drugs.

- Who had started a significantly restrictive diet during the four weeks preceding the
first dose of study medication (qualifying session).

- Who had donated blood or plasma within 30 days prior to the first dose of study
medication.

- Male subjects with hemoglobin less than 125 g/L and female subjects with hemoglobin
less than 115 g/L.

- Who had participated in another clinical trial within 30 days prior to the first dose
of study medication (qualifying session).

- Who had used any over-the-counter (OTC) medication, including vitamins and natural
health products, within seven days prior to the first dose of study medication
(qualifying session) without evaluation and approval by the study investigator.

- Who had used any prescription medication, except hormonal contraceptives or hormonal
replacement therapy, within seven days prior to the first dose of study medication
(qualifying session) without evaluation and approval by the study investigator.

- Who had a history of glaucoma or any other pupil abnormalities that in the opinion of
the qualified investigator or designee could interfere with the ability to perform
pupillometry.

- Who were not able to abstain from nicotine smoking while being in the clinical unit

- Who had had a positive test for or been treated for hepatitis B, hepatitis C or HIV.

- Who had current or pending legal charges.

- Who, in the opinion of the investigator, was not considered to be suitable and was
unlikely to comply with the study protocol for any reason.

Descriptive Information
Brief Title  ICMJE Study to Determine the Bioavailability, Pharmacodynamic Effects, and Safety of Whole and Crushed ALO-01 Compared to Morphine Sulfate Immediate Release (MSIR)
Official Title  ICMJE A Randomized, Double-Blind, Triple-Dummy, Single-Dose, Four-Way Crossover Study to Determine the Relative Bioavailability, Pharmacodynamic Effects, and Safety of Equivalent Doses of Whole and Crushed ALO-01 Versus Morphine IR in Opioid Experienced, Non-Dependent Subjects
Brief SummaryThe purpose of the study is to determine the relative pharmacodynamic effects and safety of crushed and whole ALO-01 compared to MSIR and to Placebo, and of crushed ALO-01 to whole ALO-01; to determine the relative bioavailability of plasma morphine from crushed and whole ALO-01 compared to MSIR, and from crushed ALO-01 to whole ALO-01; and to determine the relative bioavailability of plasma naltrexone and 6-?-naltrexol from crushed ALO-01 to whole ALO-01.
