Outcome Measures

Primary Outcomes (2)

  • Incidence and severity of TEAEs and SAEs

    Incidence and severity of treatment emergent adverse events (TEAEs) and Serious Adverse Events (SAEs) after multiple doses of MN-08 administered for 6.5 consecutive days in healthy subjects.

    Through study completion, an average of 12 days

  • Incidence and severity of treatment-related adverse events

    Incidence and severity of treatment-related adverse events determined by changes from screening (baseline) of findings from vital signs, ECG, and clinical laboratory parameters per the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.

    Through study completion, an average of 12 days

Secondary Outcomes (9)

  • Single dose peak plasma concentration (Cmax) for MN-08

    Pre dose and up to 12 hours post dose after the morning dosing of Day 1.

  • Single dose area under the plasma concentration versus time curve (AUC) for MN-08

    Pre dose and up to 12 hours post dose after the morning dosing of Day 1.

  • Single dose time to peak plasma concentration (Tmax) for MN-08

    Pre dose and up to 12 hours post dose after the morning dosing of Day 1.

  • Repeated dose peak plasma concentration (Cmax) for MN-08

    Pre dose and up to 120 hours post dose after the morning dosing of Day 7.

  • Repeated dose steady-state plasma concentration (Css) for MN-08

    Pre dose and up to 120 hours post dose after the morning dosing of Day 7.

  • +4 more secondary outcomes

Study Arms (2)

cohort 1:MN-08 24 mg/day

EXPERIMENTAL

2 x 6 mg MN-08 tablets for a total dose of 12 mg or 2 matching placebo tablets (given approximately every 12 hours) for 6.5 consecutive days, until the morning dose of Day 7.

Drug: MN-08 24 mg/day

cohort 2:MN-08 60 mg/day

EXPERIMENTAL

5 x 6 mg MN-08 tablets for a total dose of 30 mg or 5 matching placebo tablets (given approximately every 12 hours) for 6.5 consecutive days, until the morning dose of Day 7.

Drug: MN-08 60 mg/day

Interventions

Subjects in this cohort will receive 12 mg MN-08 tablets b.i.d. for a total daily dose of 24 mg or matching placebo for 6 consecutive days, and the last dose (12 mg) on the morning of Day 7.

cohort 1:MN-08 24 mg/day

Subjects in this cohort will receive 30 mg MN-08 tablets b.i.d. for a total daily dose of 60 mg or matching placebo tablets for 6 consecutive days, and the last dose (30 mg) on the morning of Day 7.

cohort 2:MN-08 60 mg/day

Eligibility Criteria

Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects must meet all the following criteria to be included in the study:
  • Male or female, non-smoker (no use of tobacco or nicotine products within 3 months prior to screening), ≥ 18 and ≤ 45 years of age, with body mass index (BMI) \> 18.0 and \< 30.0 kg/m2 , and body weight ≥ 50.0 kg for males and ≥ 45.0 kg for females.
  • Healthy as defined by:
  • the absence of a clinically significant history of neurological, endocrine, cardiovascular, respiratory, hematological, immunological, psychiatric, gastrointestinal, renal, hepatic, and metabolic disease.
  • Female subjects must not be pregnant, breastfeeding, or at risk to become pregnant during study participation. Female subjects must have a negative serum pregnancy test at screening (within 72 hours of the first dose of study medication) if of childbearing potential, or be of non-childbearing potential. Non-childbearing potential is defined as:
  • post-menopausal female (absence of menses for 12 months prior to the first study drug administration, or having had a bilateral oophorectomy, or hysterectomy with bilateral oophorectomy at least 6 months prior to the first study drug administration); or
  • surgically sterile female (hysterectomy or tubal ligation at least 6 months prior to drug administration).
  • Female subjects of childbearing potential (childbearing potential defined as not post menopausal nor surgically sterile) must agree to use a reliable method of birth control (see below for details) or remain abstinent during the study, starting with the screening visit until at least 90 days after the last study drug administration.
  • Male subjects who have not been vasectomized for at least 6 months, and who are sexually active with a female partner of childbearing potential must be willing to use one of the following acceptable contraceptive methods from the first study drug administration until at least 90 days after the last study drug administration:
  • simultaneous use of a male condom and, for the female partner, hormonal contraceptives used since at least 4 weeks prior or intra-uterine contraceptive device placed since at least 4 weeks prior to study.
  • simultaneous use of a male condom and, for the female partner, a diaphragm or cervical cap with intravaginally applied spermicide.
  • Male subjects (including men who have had a vasectomy) with a pregnant partner must agree to use a condom from the first study drug administration until at least 90 days after the last study drug administration.
  • Male subjects must be willing not to donate sperm until 90 days following the last study drug administration
  • Capable of signing the informed consent form.

You may not qualify if:

  • Subjects to whom any of the following applies will be excluded from the study:
  • Any clinically significant abnormality at physical examination, clinically significant abnormal laboratory test results or positive test for hepatitis B, hepatitis C, or HIV found during medical screening.
  • Subjects with any following clinical illness at screening, including but not limited to respiratory, circulatory, digestive, hematological, endocrine, immunological, dermatological, and ENT abnormalities.
  • Subjects with digestive, liver, or kidney diseases which could affect the pharmacokinetics of drugs.
  • Positive urine drug screen, alcohol breath test, or urine cotinine test at screening.
  • History of allergic reactions to MN-08 or other related drugs, or to any excipient in the formulation.
  • Positive pregnancy test at screening.
  • Clinically significant ECG abnormalities or vital sign abnormalities, including: systolic BP lower than 90 or over 139 mmHg, diastolic BP lower than 60 or over 89 mmHg, or HR less than 55 or over 100 bpm; orthostatic BP: decrease in systolic blood pressure of 20 mmHg or higher, decrease in diastolic blood pressure of 10 mmHg or higher, or increase in heart rate of 30 bpm or higher within 2 to 3 minutes after passing from a supine to a standing position at screening.
  • History of significant alcohol abuse within 1 year prior to screening or regular use of alcohol within 6 months prior to the screening visit (more than 14 units of alcohol per week \[1 unit = 150 mL of wine, 360 mL of beer, or 45 mL of 40% alcohol\]).

  • Subjects drinking excessive amounts of tea, coffee, or caffeinated beverages (more than 8 cups,1 cup = 250 mL) every day before the screening, or those who cannot agree to prohibit drinking tea, coffee, and/or products containing caffeine, grapefruit, or poppy 24 hours before dosing and during the study period.
  • Smoking history of 5 cigarettes per day within 3 months before the study, or those who cannot stop smoking 24 h before dosing and during the study period.
  • Have undergone major surgery 6 months before the study, or plan to have surgery during the study.
  • Have been vaccinated within 3 months prior to the study.
  • Participation in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days prior to the first dosing, administration of a biological product in the context of a clinical research study within 90 days prior to the first dosing, or concomitant participation in an investigational study involving no drug or device administration.
