About

The purpose of this study was to evaluate the safety, tolerability, and pharmacokinetics of MLN3126 when administered as a single dose of tablets at escalating dose levels in healthy participants.

Full description

The drug tested in this study is called MLN3126. The study evaluated the safety, tolerability, pharmacokinetics (PK), pharmacodynamics and the potential effect of food on the PK of MLN3126 and its M-I metabolite following single oral dose administrations.

This study planned to enroll approximately 48 healthy participants, who were to be enrolled in 1 of the 6 dose cohorts or matching placebo in an ascending fashion. Participants were randomly assigned to MLN3126 or placebo within each cohort- which remained undisclosed to the participant and study doctor during the study (unless there was an urgent medical need):

• Cohort 1 - MLN3126 300 mg or matching placebo
• Cohort 2 - MLN3126 600 mg or matching placebo
• Cohort 3 - MLN3126 1000 mg or matching placebo
• Cohort 3 - MLN3126 1000 mg or matching placebo (fed regimen)
• Cohort 4 - MLN3126 1500 mg or matching placebo
• Cohort 5 - MLN3126 2000 mg or matching placebo
• Cohort 6 - Did not taken place due to termination of the study

All participants were asked to take the required tablets at the same time throughout the study.

This single-centre trial was conducted in The United States. Participants were confined to the clinic for 5 days, and were contacted by telephone on day 14 (±2days) for a follow-up assessment.

This study was terminated after completion of Cohort 5 due to findings of study site non-compliance to Good Clinical Practice (GCP) regarding study documentation. There were no safety concerns.

Enrollment: 39 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. In the opinion of the investigator, the participant was capable of understanding and complying with protocol requirements.
2. The participant or, when applicable, the participant's legally acceptable representative signed and dated a written, informed consent form and any required privacy authorization prior to the initiation of any study procedures.
3. Is a male or female adult, aged 18 to 55 years, inclusive, at the time of informed consent and study drug dosing.
4. Is a healthy adult male or female subject as evidenced by their medical history, complete physical examination, vital signs, ECG, and safety laboratory evaluations.
5. Weighed at least 45 kg (99 lbs) and had a body mass index (BMI) between 18 and 30.0 kg/m2 inclusive at Screening.
6. A male participant who was nonsterilized and sexually active with a female partner of childbearing potential agreed to use adequate contraception from signing of informed consent throughout the duration of the study and for 12 weeks after last dose. In addition, participants were advised not to donate sperm during this period.
7. A female participant of childbearing potential who was sexually active with a nonsterilized male partner agreed to use routinely adequate contraception from signing of informed consent throughout the duration of the study to their next postconfinement menstruation. In addition participants were advised not to donate ova during this period.

Exclusion criteria

Any participant who meets any of the following criteria will not qualify for entry into the study:

1. Has received any investigational compound within 30 days prior to the first dose of study medication.
2. Is an immediate family member, study site employee, or in a dependent relationship with a study site employee who is involved in the conduct of this study (eg, spouse, parent, child, sibling) or may consent under duress.
3. Has uncontrolled, clinically significant neurologic, cardiovascular, pulmonary, hepatic, renal, metabolic, GI, or endocrine disease or other abnormality, which may impact the ability of the participant to participate or potentially confound the study results.
4. Has a known hypersensitivity to any component of the formulation of MLN3126.
5. Has a positive urine drug result for drugs of abuse at Screening or Check-in (Day -1).
6. Has a history of drug abuse (defined as any illicit drug use) or a history of alcohol abuse (defined as 4 alcoholic beverages per day) within 1 year prior to the Screening visit or is unwilling to agree to abstain from alcohol and drugs throughout the study.
7. Has taken any excluded medication, supplements, or food products listed in the Excluded Medications and Dietary Products section of the protocol.
8. If female, the participant is pregnant or lactating or intending to become pregnant, or intending to donate ova, before or during, the study; including the timeframe to participant's next postconfinement menstruation after participating in this study.
9. If male, the participant intends to donate sperm during the course of this study or for 12 weeks thereafter.
10. Has evidence of current cardiovascular, central nervous system, hepatic, hematopoietic disease, renal dysfunction, metabolic or endocrine dysfunction, serious allergy, asthma hypoxemia, hypertension, seizures, or allergic skin rash. There is any finding in the participant's medical history, physical examination, or safety laboratory tests giving reasonable suspicion of a disease that would contra indicate taking MLN3126 or a similar drug in the same class, or that might interfere with the conduct of the study. This includes, but is not limited to, peptic ulcer disease, seizure disorders, and cardiac arrhythmias.
11. Has current or recent (within 6 months) GI disease that would be expected to influence the absorption of drugs (ie, a history of malabsorption, any surgical intervention known to impact absorption [eg, bariatric surgery or bowel resection], esophageal reflux, peptic ulcer disease, erosive esophagitis or frequent [more than once per week] occurrence of heartburn).
12. Has a history of cancer or other malignancy, except basal cell carcinoma that has been in remission for at least 5 years prior to Day 1.
