About

The purpose of this study is to determine the Effects of KP-001 on Metformin (a substrate of MATE1) and Midazolam (a substrate of CYP3A4) Pharmacokinetics and the Effect of Clarithromycin (potent CYP3A4/P-gp Inhibitor) on KP-001 Pharmacokinetics in Healthy Adult Participants. The study will also evaluate the safety and tolerability of KP-001 with and without a single dose or multiple doses of an interaction drug. The study comprises 3 parts. Participants will stay in the Clinical Unit during the study, depending on which part they assigned to. Participants will remain at the clinical site for a 13 day/12 night in-house stay (Part 1), a 14 day/13 night in house stay (Part 2), or a 11 day/10 night in-house stay (Part 3).

Enrollment: 38 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Participant voluntarily agrees to participate in this study and signs an Institutional Review Board (IRB)-approved informed consent prior to performing any of the Screening Visit procedures.

2. Participants who are male or female, 18-55 years of age, inclusive, at screening.

3. Participant is a continuous non-smoker who has not used nicotine-containing products for at least 3 months prior to Day -1 of Treatment Period 1 and throughout the study, based on participant self-reporting and the result of cotinine test at screening and/or Day -1 of Treatment Period.

4. Participant is medically healthy with no clinically significant abnormal screening results (e.g., medical history, physical examination, laboratory profiles, vital signs, or ECGs), in the opinion of the Investigator or designee. If screening and/or admission results are abnormal, they may be repeated once at screening and/or once at admission to confirm the participant's eligibility.

5. Participant has body weight ≥ 50.0 kg and BMI within the range 18.0 to 30.0 kg/m2 (inclusive) at screening.

6. Participant is a woman of non-childbearing potential who:

   1. Is postmenopausal with amenorrhea for at least 1 year prior to screening and with follicle-stimulating hormone (FSH) of 40 IU/L or higher.

      OR

   2. Has undergone one of the following:

      • bilateral tubal ligation or bilateral salpingectomy
      • hysterectomy
      • bilateral oophorectomy

7. Male participant who is sexually active with female partner(s) of childbearing potential must agree to use both a condom and spermicide from the first dose until 91 days after the last dose of KP-001.

8. Male participant must agree not to donate sperm from the first dose until 91 days after the last dose of KP-001.

Exclusion criteria

1. Participant is Japanese, Korean or Chinese descent.
2. Participant is legally, mentally or physically incapacitated or, in the opinion of the Investigator, has significant mental or emotional problems, including psychiatric illness (e.g., depression and/or anxiety) at the time of the Screening Visit, or that could reasonably be expected to develop during the conduct of the study.
3. Participant has a significant history or clinical manifestation of any metabolic, allergic, dermatologic, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, or psychiatric disorder as determined by the Investigator or designee.
4. Participant has a history of any illness that, in the opinion of the Investigator or designee, might confound the results of the study or poses an additional risk to the participant by their participation in the study.
5. Participant used any prescription or non-prescription medications (including vitamins, recreational drugs, and dietary or herbal supplements) within 14 days or 5 half-lives (whichever is longer) prior to Day -1 of Treatment Period 1 and until completion of the Follow-up visit unless, in the opinion of the Investigator, may be treatment for an adverse event (AE) or will not interfere with the interpretation of safety.
6. Participant underwent blood donation or transfusion within 56 days prior to Day -1 of Treatment Period 1.
7. Participant has a history or presence of hypersensitivity or idiosyncratic reaction to any components of the KP-001 formulation or any components of formulation used as study intervention during the study.
8. Participant has a history of drug or alcohol abuse [regular alcohol consumption exceeding 14 drinks/week (1 drink = 5 ounces of wine, 12 ounces of beer, or 1.5 ounces of hard liquor) within one year before the Screening Visit.
9. Participant has a complication of drug allergies or history of drug allergies.
10. Female participant has a positive pregnancy test or is lactating.
11. Participant used any investigational drug in the last 30 days or 5 half-lives (if known), whichever is longer, prior to Day -1 of Treatment Period 1.

13. Participant had any major surgical procedure within 30 days prior to Day -1 of Treatment Period 1 or any planned surgery during study period.
14. Participant had any laboratory abnormality that, in the judgment of the Investigator, would put the participant at unacceptable risk for participation in the study or may interfere with the assessments included in the study.
15. Participant has abnormal findings on the screening ECG deemed clinically significant by the Investigator or qualified designee.
16. Participant is an employee of the Sponsor or any contract research organization (CRO) involved in the study, the Investigator, or an immediate family member (partner, offspring, parents, siblings, or sibling's offspring) of an employee involved in the study.
