Interventional
Description of intervention(s) / exposure
Treatment: Drugs - D-4517.2

Experimental: Cohort 1: 0.25 mg/kg D-4517.2 - Participants will be administered a single dose of 0.25 mg/kg D-4517.2. A sentinel participant will be enrolled for each cohort. After the sentinel participant completes Day 3, the safety review committee (SRC) will determine if it is safe to continue with the enrollment of the remaining 3 participants in the cohort. The SRC will also determine the dose escalation to the next cohort.

Experimental: Cohort 2: 0.5 mg/kg D-4517.2 - Participants will be administered a single dose of 0.5 mg/kg D-4517.2. A sentinel participant will be enrolled for each cohort. After the sentinel participant completes Day 3, the SRC will determine if it is safe to continue with the enrollment of the remaining 3 participants in the cohort. The SRC will also determine the dose escalation to the next cohort.

Experimental: Cohort 3: 1.0 mg/kg D-4517.2 - Participants will be administered a single dose of 1.0 mg/kg D-4517.2. A sentinel participant will be enrolled for each cohort. After the sentinel participant completes Day 3, the SRC will determine if it is safe to continue with the enrollment of the remaining 3 participants in the cohort. The SRC will also determine the dose escalation to the next cohort.

Experimental: Cohort 4: 2.0 mg/kg D-4517.2 - Participants will be administered a single dose of 2.0 mg/kg D-4517.2. A sentinel participant will be enrolled for each cohort. After the sentinel participant completes Day 3, the SRC will determine if it is safe to continue with the enrollment of the remaining 3 participants in the cohort.

Eligibility
Key inclusion criteria
1. Is a healthy man or woman age 18 to 65 years, inclusive, at the Screening Visit;

2. Has the ability to understand and sign the written informed consent form (ICF) and
local medical privacy authorization forms, which must be obtained prior to any study
related procedures being completed;

3. Body mass index (BMI) between 18 and 32 kg/m^2, inclusive, with body weight = 100 kg;

4. Is in general good health, based upon the results of a medical history assessment,
physical examination, vital signs, and laboratory profile, as judged by the
Investigator;

5. Female participants of non-childbearing potential must be either surgically sterile
(hysterectomy, bilateral tubal ligation, salpingectomy, and/or bilateral oophorectomy
at least 26 weeks before the Screening Visit) or postmenopausal, defined as
spontaneous amenorrhea for at least 1 years, with follicle-stimulating hormone (FSH)
in the postmenopausal range at screening, based on the central laboratory's ranges;

6. Female participants of childbearing potential (i.e., ovulating, premenopausal, and not
surgically sterile) and all male participants must use a medically accepted
contraceptive regimen (including hormonal contraceptives) during their participation
in the study and for 30 days after the last administration of study drug. Medically
accepted contraceptive methods are defined as those with 90% or greater efficacy;

7. Acceptable methods of contraception for male participants enrolled in the study
include the following:

• Condoms or surgical sterilization of participant at least 26 weeks before the
Screening Visit (vasectomy);

Acceptable methods of contraception for female participants enrolled in the study
include the following:

- Surgical sterilization of participant at least 26 weeks before the Screening
Visit (includes hysterectomy or bilateral tubal ligation, oophorectomy, or
salpingectomy);

- Intrauterine device for at least 4 weeks before the Screening Visit; or

- Hormonal contraception (oral, implant, injection, ring, or patch) for at least 4
weeks before the Screening Visit;

8. If male, participants must agree to abstain from sperm donation through 90 days after
administration of the last dose of study drug;

9. Female participants may not be pregnant, lactating, or breastfeeding;

10. Female participants of childbearing potential must have negative result for pregnancy
test at screening and Check-in;

11. Participants must have a negative test result for hepatitis B surface antigen (HBsAg),
hepatitis C virus antibody (HCVab), and human immunodeficiency virus (HIV) antibody at
screening;

12. Participants must have an estimated glomerular filtration rate (eGFR) of =60
mL/min/1.73m^2 at screening;

13. Participants must have a negative urine test for drugs of abuse, cotinine, and breath
alcohol test at screening and Check-in; and

14. Participants must be willing and able to abide by all study requirements and
restrictions.

acetaminophen), vitamins/herbal supplements (with the exception of hormonal
contraceptives) within 14 days prior to Day 1;

12. Has used any other study drug within 30 days or 5 half-lives of the drug (whichever is

15. Has any finding that, in the view of the Investigator or Medical Monitor, would
compromise the participant's safety requirements; or

16. Is employed by the Sponsor, the Contract Research Organization (CRO), or the study
site (permanent, temporary contract worker, or designee responsible for the conduct of
