Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Obeldesivir will be administered orally at the study site in the morning with 240 mL of water
following an overnight fast (no food or drinks, except water) for at least 10 hours. Additionally, participants will be restricted from water consumption 1 hour before until 2 hours after dosing, except for the 240 mL given with the study treatment. Participants will be allowed to consume clear liquids, such as broth or juices, following collection of the 2-hour post dose blood draw.
Approximately 60 unique participants will be enrolled to obtain at least 48 evaluable participants (8 per subcohort). Cohort 1 will enroll up to 20 participants (10 with moderate RI [Cohort 1a] and up to 10 matched controls [Cohort 1b]). Cohort 2 will enroll 20 participants (10 with severe RI [Cohort 2a] and 10 matched controls [Cohort 2b]). Cohort 3 will enroll up to 20 participants (10 with mild RI [Cohort 3a] and up to 10 matched controls [Cohort 3b]). Each participant with RI will have a matched control participant with normal renal function in the control subgroup.
Single oral dose of ODV 350 mg on Day 1 for mild and moderate RI and their matched controls; Single oral dose of ODV 175 mg on Day 1 for severe RI and their matched controls
ODV is administered as: Oral tablet
Each dose of study drug administered at the study site will be administered by qualified study site staff. The dose of study drug administered to participants will be done at the clinic under staff supervision and will be accurately recorded on source document and the study drug accountability form
Intervention code [1] 327205 0
Treatment: Drugs
Comparator / control treatment
Participants with normal renal functions will receive the same ODV dose as their matched renal impaired participant (ie, Cohort 1b and 3b to receive ODV 350 mg and Cohort 2b to receive ODV 175 mg).
Control group
Active

Outcomes
Primary outcome [1] 336335 0
To evaluate the single-dose pharmacokinetics (PK) of obeldesivir (ODV; GS-5245) in participants with renal impairment (RI) relative to matched control participants with normal renal function. Plasma PK Parameters to include Cmax, Clast, Tmax, Tlast, AUClast, AUCinf, %AUCexp, and t1/2.
Timepoint [1] 336335 0
To determine PK outcomes, blood samples will be collected on Day 1: predose (5 min before dose), 0.25, 0.5, 0.75, 1.5, 2, 3, 4, 6, 12 hours post dose; Day 2: 24 hours post dose; Day 3: 48 hours post dose; Day 4: 72 hours post dose, Day 5: 96 hours post dose; Day 6: 120 hours post dose, Day 7: 144 hours post dose, Day 8: 168 hours post dose; Day 9: 192 hours post dose; Day 10: 216 hours post dose and Day 11: 240 hours post dose.
Secondary outcome [1] 427891 0
This is a composite secondary outcome, which will be determined via the monitoring of adverse events, serious adverse events, concomitant medications, clinical laboratory analyses, vital signs measurements, electrocardiograms, and physical examinations
Timepoint [1] 427891 0
Adverse events and concomitant medications assessed daily to day 11 and at day 18 by telephone contact; vital signs taken daily to day 11; blood and urine samples for clinical laboratories taken on days 2, 5, 8 and 11; serum pregnancy test on day 11; 12-lead ECG conducted on days 5 and 11.

Eligibility
Key inclusion criteria
Criteria 1-8 apply to all cohorts including healthy participants:
1) Have the ability to understand and sign a written informed consent form (ICF), which must be obtained prior to initiation of study procedures.
2) Be aged 18 through 79 years, inclusive, at screening and at admission.
3) Have a calculated BMI of at least 18.0 and no greater than 38.0 kg/m2 at screening.
4) Participants assigned male at birth and participants assigned female at birth and of
childbearing potential who engage in heterosexual intercourse must agree to use
protocol-specified methods of contraception.
5) Have not donated blood within 56 days of study entry or plasma within 7 days of study entry and must refrain from blood donation from clinic admission, throughout the study period, and continuing for at least 30 days following study drug administration
6) Laboratory evaluations and 12-lead ECG evaluations at screening and admission must be without clinically significant abnormalities as assessed by the investigator.
7) Must be willing and able to comply with all study requirements.
8) Must, in the opinion of the investigator, be in good health (with the exception of renal
function in the mild, moderate, and severe RI groups) based upon medical history and
physical examination (PE), including vital signs.
In addition to the criteria listed above, participants with RI must also meet the following
additional inclusion criteria to be eligible for participation in this study:
9) Must have an unchanged RI classification during the 3 months prior to screening and no
evidence of worsening of clinical and/or laboratory signs of RI within the screening period.
10) Must have an eGFRCKD-EPI,creatinine at screening of:
60 less than or equal to eGFRCKD-EPI,creatinine < 90 mL/min/1.73 m2 for mild disease (Cohort 3a) or
30 less than or equal to eGFRCKD-EPI,creatinine < 60 mL/min/1.73 m2 for moderate disease (Cohort 1a) or
15 less than or equal to eGFRCKD-EPI,creatinine < 30 mL/min/1.73 m2 for severe disease (Cohort 2a).
11) Have hepatic transaminase (aspartate aminotransferase [AST] and alanine aminotransferase
[ALT]) less than or equal to 2 x upper limit of normal (ULN) at screening and at admission.
In addition to the criteria listed above, matched control participants must also meet the following additional inclusion criteria to be eligible for participation in this study:
