Safety, Tolerability, Pharmacokinetics (PK), and Food Effect of MK-7762 in Healthy Adults

Completed · Phase 1 · Has a placebo group

Conditions studied: Tuberculosis

In brief

The goal of this clinical trial is to assess the safety, tolerability, and pharmacokinetics of single and then multiple doses of MK-7762 (TBD09) in healthy volunteers in the context of a first-in-human study. The effect of food on the rate and extent of absorption of a single oral dose of MK-7762 (TBD09) will also be evaluated.

Age: 19 and older, up to 55. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• To be included in this trial, an individual must satisfy all the following criteria:
• Is ≥ 19 to ≤ 55 years of age.
• Is healthy as determined by the Investigator via medical history and clinical examination before enrollment in the trial.
• Can understand and comply with the trial and site procedures, understand the risks involved in the trial, and provide written informed consent before the first trial-specific procedure.
• Can complete all Screening period evaluations and stay in the clinical research facility for the duration of the inpatient periods of the trial.
• Has BMI between 18 and 32 kg/m2, inclusive, and body weight not less than 50 kg at Screening.
• Has resting vital signs at Screening within the following ranges: Systolic blood pressure (SBP) ≥100 mmHg Diastolic blood pressure (DBP) ≥50 mmHg Heart rate ≤100 beats per minute (bpm) Note: If vital signs are out of range, the Investigator may obtain two additional readings within the Screening period.
• Has a 12-lead ECG consistent with normal cardiac conduction and function at Screening, including: HR between 45 and 100 bpm (inclusive); QTcF ≤450 ms for males and ≤470 ms for females; QRS interval <120 ms; PR interval <220 ms; and morphology consistent with healthy cardiac conduction.
• Is a nonsmoker within the previous 6 months before Screening, and does not use tobacco containing, or nicotine-containing products, including, but not limited to, cigarettes, pipes, cigars, chewing tobacco, e-cigarettes, nicotine patch, or nicotine gum.
• Has clinical chemistry, hematology, coagulation, and complete urinalysis (fasted for at least 8 hours) results at Screening within the reference range for the testing laboratory unless the out-of-range results are deemed not clinically significant by the Investigator.
• Has negative results for hepatitis B surface antigen (HbsAg) and hepatitis C virus antibody (HCV Ab) within 3 months prior to Day -1 or at Screening.
• Has negative test results for HIV antibody within 3 months prior to Day -1 or at Screening.
• Has a negative urine drug screen result at Screening and on Day -1. The presence of alcohol or marijuana in the urine is not exclusionary unless the Investigator determines that the participant's marijuana use qualifies as substance abuse (see Section 5.2, Exclusion Criteria 6).
• If individual's assigned sex at birth is female, they must be of non-childbearing potential based on either of the following: a. Is post-menopausal defined as amenorrhea for at least 12 months in absence of any exogenous hormonal treatments and follicle stimulating hormone (FSH) levels in the laboratory-defined postmenopausal range, or, b. Reports being surgically sterilized (i.e., tubal ligation, hysterectomy, bilateral oophorectomy/salpingectomy)
• If individual is assigned male sex at birth, is not sterilized, and is sexually active with a female partner of childbearing potential, agrees to use condoms from Day -1 through 90 days after the last dose of study drug. They must also agree to not donate sperm during the trial and for 3 months (90 days) after receiving the last dose of study drug.

You may not qualify if…

• If an individual meets any of the following criteria, they are ineligible for this trial:
• Has current or past history of a clinically significant cardiovascular, cerebrovascular, respiratory, gastrointestinal, hematologic, renal, hepatic, immunologic, metabolic, urologic, neurologic, dermatologic, psychiatric, or other major disease, as determined by the Investigator.
• Has history of or Screening findings of abnormalities of vision, including corrected visual acuity worse than 20/25 in either eye based on Screening assessment using Snellen chart and Rosenbaum pocket chart, or color vision impairment based on Screening assessment using Ishihara plates. Candidates with ametropia corrected to 20/25 or better do not have to be excluded.
• Has history of or Screening findings of peripheral neuropathy, such as numbness or abnormal reflexes.
• Has history of or current clinically relevant cardiovascular disorder, such as heart failure, coronary artery disease, uncontrolled hypertension, arrhythmia, tachyarrhythmia, prolonged QT syndrome, or presence of symptom(s) strongly suggestive of such a problem, such as exertional chest pressure/pain or unexplained syncope.
• Had an active malignancy within 5 years from Screening, except basal cell or squamous cell skin cancers. Any history of breast cancer or melanoma will be exclusionary.
• Has history of any drug abuse within 1 year prior to Screening or has used any hard drugs (such as cocaine, phencyclidine [PCP], natural and synthetic opiates, and amphetamine derivatives) within 1 year prior to Screening. Individuals that have taken an opioid or amphetamine medication within the previous year prior to Screening that was prescribed by a healthcare provider will not be excluded unless they are currently taking the medication at the time of Screening.
• Has history of regular alcohol consumption exceeding 14 drinks/week (1 drink = 5 ounces [150 mL)] of wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) within 6 months of Screening or alcohol abuse within 1 year prior to Screening.
• Had any surgical or medical condition or history that, in the opinion of the Investigator, may potentially alter the absorption, metabolism, or excretion of study treatment, such as, but not limited to, gastric bypass or banding surgery or gastric or duodenal ulcers.
• Is taking any of the following prohibited medications or vaccinations: a. Any prescription or over-the-counter medication, vitamin or dietary supplement, or herbal product within 14 days prior to Day -1. b. Received any vaccination within 14 days prior to Day -1, including COVID-19 vaccination.

• Has participated in other trials involving administration of an investigational drug or device within 30 days or 5 half-lives, whichever is longer, before Screening for the current trial and during participation in the current trial.
• Has a positive PCR or antigen test result for COVID-19/SARS-CoV-2 at check-in to the Clinical Trials Unit.
• Has a condition that the Investigator believes would interfere with the participant's ability to provide written informed consent, comply with trial instructions, or which might confound the interpretation of the trial results or put the participant at undue risk.
