简要总结
The purpose of this study is to evaluate the safety and tolerability of single and multiple doses of the antisense inhibitor ION547 administered subcutaneously (SC) in healthy participants.
详细描述
This is a Phase 1, double-blind, randomized, placebo-controlled, dose escalation study of ION547 in up to 76 participants. Participants will be randomized to receive single and multiple doses of ION547 or placebo SC. The maximum length of participation in the study will be approximately 34 weeks.

- •Healthy males or females 18 to 65, inclusive, at the time of informed consent.
- •Satisfy the following:
- •a. Females: Women of childbearing potential are not allowed to participate in this study.
- •b. Males must be abstinent, surgically sterile (vasectomy with negative semen analysis at Follow-up, or a surgically sterile non-pregnant female partner) or if engaged in sexual relations with a woman of childbearing potential (WOCBP), participant is utilizing a highly effective contraceptive method

排除标准
- •Clinically significant abnormalities in medical history or physical examination.
- •Screening laboratory results as follows, or any other clinically significant (CS) abnormalities in screening laboratory values that would render a participant unsuitable for inclusion:
- •Urine protein/creatinine (P/C) ratio greater than or equal to (≥) 0.2 milligrams (mg)/mg.
- •Positive test (including trace) for blood on urinalysis.
- •Alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, alkaline phosphatase (ALP), serum creatinine, and blood urea nitrogen (BUN) > upper limit of normal (ULN).
- •Hemoglobin A1c (HbA1c) > ULN
- •Platelet count < lower limit of normal (LLN)
- •aPTT > ULN
- •Evidence of uncorrected hypothyroidism or hyperthyroidism based on thyroid function results at Screening.
- •Uncontrolled hypertension (blood pressure [BP] > 160/100 millimeters of mercury [mmHg]).
- •Malignancy within 5 years, except for basal or squamous cell carcinoma of the skin or carcinoma in situ of the cervix that has been successfully treated.
- •Treatment with another investigational drug, biological agent, or device within 1 month of Screening, or 5 half-lives of investigational agent, whichever is longer.
- •Previous treatment with an oligonucleotide (including small interfering ribonucleic acid [siRNA]) within 4 months of screening if single dose received, or within 12 months of screening if multiple doses received. Exclusion does not apply to Covid-19 messenger ribonucleic acid (mRNA) vaccines.
- •History of bleeding diathesis or coagulopathy.
- •Regular use of alcohol within 6 months prior to screening (> 7 drinks/week for females, > 14 drinks/week for males [1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of hard liquor]), or use of soft drugs (such as marijuana) within 3 months prior to screening, or hard drugs (such as cocaine and phencyclidine [PCP]) within 1 year prior to screening, or positive urine drug screen at Screening.
- •Concomitant medication restrictions: the use of prescription and over-the-counter medications including nonsteroidal anti-inflammatory drugs (with the exception of occasional acetaminophen or ibuprofen) and herbal remedies at Screening and throughout the Study Period.
- •Smoking limitations: more than 10 cigarettes/day at Screening and those with a significant change in smoking habits within 1 month prior to Screening should be excluded.
- •Blood donation of 50 to 499 mL within 30 days of Screening or of > 499 mL within 60 days of Screening.
