Safety, Tolerability and Pharmacokinetics of KPG-818 in Healthy Subjects

Completed · Phase 1 · Has a placebo group

Conditions studied: Systemic Lupus Erythematosus

In brief

This is a Phase 1 study to investigate the safety, tolerability and pharmacokinetics (PK) of KPG-818 in healthy male and female participants and the effect of food on the PK of KPG-818. The study will assist in identifying appropriate, well tolerated doses that can be administered in subsequent studies in healthy participants and participants with systemic lupus erythematosus (SLE).

• A female participant is eligible to participate if she is not a woman of childbearing potential (WOCBP) as defined in Appendix 4. Female participants must have been surgically sterilized (bilateral oophorectomy or bilateral salpingectomy at least 3 months before the start of the study and/or hysterectomy); have premature ovarian failure confirmed by a specialist gynecologist; be postmenopausal (defined as ≥ 50 years and naturally [spontaneously] amenorrheic (postmenopausal) for ≥ 12 months); or have XY genotype, Turner syndrome or uterine agenesis.
• Capable of giving signed informed consent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.

• Any clinically important illness, medical/surgical procedure or trauma within 4 weeks of the first administration of study intervention.
• Any clinically important abnormalities in clinical chemistry, hematology or urinalysis results as judged by the Investigator, and confirmed by a repeat measurement at the Screening Visit or at admission (Day -1).
• Any positive result at the Screening Visit for serum hepatitis B surface antigen, hepatitis C antibody and human immunodeficiency virus (HIV).
• Abnormal vital signs, after 5 minutes supine rest, as judged by the Investigator to be clinically significant, and confirmed by a repeat measurement at the Screening Visit or at admission (Day -1).
• Any history or presence of an abnormal ECG, which, in the Investigator's opinion, is clinically significant, confirmed by a repeat measurement at the Screening Visit or at admission (Day-1).
• History of severe allergy/hypersensitivity or ongoing clinically important allergy/hypersensitivity, as judged by the Investigator or history of hypersensitivity to drugs with a similar chemical structure or class to KPG-818.
• Judgment by the Investigator that the participants should not participate in the study if they have any ongoing or recent (i.e., during the Screening Period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions and requirements.
• Use of drugs with enzyme inducing properties such as St John's Wort within 3 weeks prior to administration of study intervention.
• Use of any prescribed or non-prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), herbal remedies, megadose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks prior to administration(s) of study intervention or longer if the medication has a long half-life.
