Evaluating the Safety, Tolerability, and Pharmacokinetics of DF-003 in Healthy Subjects

Running, not enrolling · Phase 1 · Has a placebo group

Conditions studied: Healthy, Safety and Tolerability

In brief

The goal of this clinical trial is to evaluate the safety, tolerability, and pharmacokinetics (PK; drug metabolism) of DF-003 after oral administration of single and multiple ascending doses in healthy subjects. The choice of using healthy subjects is standard in establishing the preliminary safety and PK profile of a drug. DF-003 is a potent small molecule inhibitor of alpha-kinase 1 (ALPK1), which plays an important role in immunity and inflammation. DF-003 can inhibit the immune inflammatory response and has been shown to reduce renal fibrosis in preclinical models. Thus, this study aims to determine the role of DF-003 in the treatment of chronic kidney disease. This study will include 2 parts. Part 1 is a single ascending dose (SAD) phase with an optional food effect (FE) assessment, while Part 2 is a multiple ascending dose (MAD) phase. Part 1 - SAD Phase with optional FE assessment will include approximately 64 subjects (up to 8 cohorts of 8 subjects each) and Part 2 - MAD Phase will include approximately 32 subjects (up to 4 cohorts of 8 subjects each). Therefore, up to 96 subjects will be included in the study. Study participants will be screened approximately 42 days within the first scheduled administration of study medication. Screening data will be reviewed to determine subject eligibility. In Part 1, subjects will be randomly assigned to receive a single oral dose of DF-003 (3 x 1 milligram capsules) or matching placebo. The doses to be evaluated in Part 2 will be determined based on review of the available safety and PK data from Part 1. Subjects will be monitored for adverse events (AEs) and data will be collected for physical examination, eye examination, vital signs, 12-lead electrocardiogram (ECG), Holter monitoring, and clinical laboratory findings at various timepoints throughout the study.

• Healthy adult male or female.
• If male, meets one of the following criteria:
• Is able to procreate and agrees not to donate sperm from the first study drug administration to at least 90 days after the last study drug administration in addition to:
• Having a female partner who is postmenopausal, surgically sterile, or otherwise incapable of becoming pregnant, OR

• Is unable to procreate; defined as surgically sterile (ie, has undergone a vasectomy at least 180 days prior to the first study drug administration).
• If female, meets one of the following criteria:
• Physiological postmenopausal status, defined as the following:
• Amenorrhea for at least 12 months prior to the first study drug administration (without an alternative medical condition); AND
• Follicle stimulating hormone (FSH) levels ≥40 mIU/mL at Screening;
• In the absence of 12 months of amenorrhea, 2 FSH measurements at least 3 months apart and in the postmenopausal range must be documented.
• Surgical postmenopausal status, defined as having had a bilateral oophorectomy or bilateral salpingo-oophorectomy with FSH levels ≥ 40 mIU/mL at Screening.
• Aged at least 18 years but not older than 55 years at the time of Screening.
• Body mass index (BMI) within 18.0 kg/m\^2 to 32.0 kg/m\^2, inclusively.
• Non- or ex-smoker (An ex-smoker is defined as someone who completed stopped using nicotine products for at least 3 months prior to the first study drug administration).
• Have no clinically significant diseases captured in the medical history or evidence of clinically significant findings on the physical examination, vital signs, eye examination, and/or ECG, as determined by an Investigator.
• A 12-lead ECG that meets the following criteria (ECG intervals will be based on the mean value of triplicate ECGs [rounded to the nearest whole number] collected at Screening):
• Heart rate ≥45 to ≤100 beats per minute
• QT interval corrected for heart rate (QTc) according to Fridericia's formula (QTcF) ≤450 ms (males) or ≤470 ms (females)
• QRS interval <120 ms
• PR interval ≤200 ms

You may not qualify if…

• Female who is lactating.
• Female who is pregnant according to the pregnancy test at Screening or prior to the first study drug administration
• Female using the following systemic contraceptives: oral, patch or vaginal ring, in the 28 days prior to the first study drug administration.
