Eligibility criteria: Inclusion Criteria:

Inclusion criteria for all participants

* Adult male or female participant, greater than or equals to (\>=) 18 years and less than or equals to (\<=) 75 years of age at the screening visit.
* Male and female participants must follow protocol-specified contraception guidance.

Guidance for Female Participants

a. Female participants of childbearing potential must agree to one of the following methods of contraception: i. Hysteroscopic sterilization or bilateral tubal ligation at least 6 months prior to dosing.

ii. Non-hormonal releasing intrauterine device (IUD) or hormonal contraceptives (e.g., oral, IUD, vaginal ring, transdermal patch, depot, implantable, etc.) for at least 3 months prior to dosing and with either a physical (e.g., condom, diaphragm, or other) or a chemical (e.g., spermicide) barrier method from the time of the screening visit.

b. In addition, female participants of childbearing potential will be advised to keep the same birth control method for at least 30 days after dosing.

c. Female participant must agree not to donate ova from dosing until at least 30 days after dosing.

Guidance for male participants. a. Male participants who are not vasectomized for at least 4 months prior to dosing and who are sexually active with a female partner of childbearing potential must be willing to use one of the following acceptable contraceptive methods from dosing until 90 days after dosing.

i. Simultaneous use of condom and hormonal contraceptive (e.g., oral, IUD, vaginal ring, patch, depot, implantable, etc.) or non-hormonal intrauterine device used for at least 3 months prior to dosing for the female partner.

ii. Simultaneous use of condom and a diaphragm or cervical cap with spermicide for the female partner.

b. No restrictions are required for a vasectomized male provided his vasectomy has been performed 4 months or more prior to dosing. A male who has been vasectomized less than 4 months prior to dosing must follow the same restrictions as a non-vasectomized male.

1. Female Participants: A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies: Is a woman of non-childbearing potential (WONCBP) OR Is a Woman of childbearing potential (WOCBP) and using a contraceptive method that is highly effective, with a failure rate of \<1 percent (%), during the study intervention period and for at least 14 days after the last dose of study intervention. The investigator should evaluate potential for contraceptive method failure (e.g., noncompliance, recently initiated) in relationship to the first dose of study intervention.
2. A WOCBP must have a negative highly sensitive pregnancy test urine or serum as required by local regulations) within specify timeframe before the first dose of study intervention. If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.
3. The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.

   * Participants must weigh at least 50 kilogram (kg) and have a Body mass index (BMI) \>= 18.0 and \<= 40.0 kilograms per square meter (kg/m\^2), at the screening visit.
   * Continuous non-smoker who has not used nicotine- and tobacco-containing products or light smoker (\<= 5 cigarettes/day or the equivalent) for the last 3 months prior to study screening.
   * Participant who understands the study procedures in the informed consent form (ICF) and is willing and able to comply with the protocol.

Additional inclusion criteria for hepatic impaired participants.

* Participants aside from HI, be sufficiently healthy for study participation based upon medical history, physical examination, vital signs, ECGs, and screening clinical laboratory profiles, as deemed by the Principal Investigator (PI) or designee, including the following:

  1. Seated blood pressure is \>= 90/40 millimeters of mercury (mmHg) and \<= 160/100 mmHg at the screening visit.
  2. Seated heart rate is \>= 40 beats per minute (bpm) and \<= 99 bpm at the screening visit.
  3. Corrected value of the interval between the Q and T waves on the electrocardiogram tracing, corrected QT interval using Fridericia formula (QTcF) is \<= 480 milliseconds (msec) and has ECG findings considered normal or not clinically significant by the PI or designee at the screening visit.
  4. Estimated creatinine clearance \>= 80 milliliters per minute (mL/min) at the screening visit.
  5. Total bilirubin \<= 6 milligrams per deciliters (mg/dL).
* Has a score on the Child-Pugh scale at the screening visit as follows:

  a. Severe HI: \>= 10 and \<= 15; or Moderate HI: \>= 7 and \<= 9; or Mild HI: \>= 5 and \<= 6.
* Participant has stable HI as defined by a diagnosis of chronic (\>= 6 months), stable (no acute episodes of illness within 30 days prior to dosing due to deterioration in hepatic function) hepatic insufficiency with features of cirrhosis due to any etiology.

Additional inclusion criteria for healthy control participants:

* Medically healthy participants with no clinically significant medical history, physical examination, screening clinical laboratory profiles, vital signs and ECGs, as deemed by the PI or designee, including the following:
