Eligibility Criteria
Inclusion
- Able to comprehend and willing to sign an informed consent form (ICF);
- Male or female subjects, between 18 and 65 years of age, inclusive;
- Within body mass index (BMI) range 18 to 40 kg/m2, inclusive;
- Negative test for selected drugs of abuse at Screening (does not include alcohol) and at Check-in (does include alcohol); positive drug screens in the hepatically-impaired subjects may be allowed with the confirmation of use of the medication under supervision of a physician)
- Negative HIV antibody and hepatitis B surface antigen (HBsAg) screens;
- Female subjects will be non-pregnant, non-lactating, and either postmenopausal for at least 1 year (with follicle-stimulating hormone (FSH) levels ≥40 mIU/mL), surgically sterile (e.g., tubal ligation, hysterectomy) for at least 90 days, or agree to use from the time of signing the ICF until 30 days after Study Discharge one of the following forms of contraception: a non-hormonal intrauterine device (IUD) with spermicide; female condom with spermicide; contraceptive sponge with spermicide; a non-hormonal intravaginal system; diaphragm with spermicide; cervical cap with spermicide; a male sexual partner who agrees to use a male condom with spermicide; or a sterile sexual partner; for all female subjects, the pregnancy test result must be negative at Screening and Check-in;
- Male subjects will either be sterile or agree to use from Check-in until 45 days following Study Discharge one of the following approved methods of contraception: a male condom with spermicide; a sterile sexual partner; or use by female sexual partner of an IUD with spermicide; a female condom with spermicide; contraceptive sponge with spermicide; an intravaginal system (e.g., NuvaRing®); a diaphragm with spermicide; a cervical cap with spermicide; or oral, implantable, transdermal, or injectable contraceptives.
- For healthy subjects with normal hepatic function:
- Normal hepatic function defined as alanine aminotransferase, aspartate aminotransferase, bilirubin, serum albumin, and gamma glutamyl transferase all within normal limits;
- The absence of clinically-relevant abnormalities identified by a detailed medical history, full physical examination, vital signs, 12-lead electrocardiogram (ECG), and clinical laboratory tests;
- Negative hepatitis panel (including HBsAg and hepatitis C virus antibody);
- No medical or surgical conditions that might significantly interfere with gastrointestinal absorption of CMX001.
- For subjects with impaired hepatic function:
- Otherwise healthy subjects as determined by a detailed medical history, complete physical examination, vital signs, 12-lead ECG, and clinical laboratory tests (abnormal findings that are related to the subject's underlying condition are acceptable);
- Satisfy the criteria for Class B or Class C of the modified Child-Turcotte-Pugh (CPT) classification (mild \[CPT score of 5 to 6 points\], moderate \[CPT score of 7 to 9 points\], and severe \[CPT score of \>9 to \<12 points\]);
- A diagnosis of chronic hepatic impairment due to cirrhosis or fibrosis, not secondary to other diseases, which is confirmed and documented by medical history, physical examination, and/or liver biopsy, hepatic ultrasound, computed tomography scan, or magnetic resonance imaging.
Exclusion
- Significant history or clinical manifestation of any significant metabolic, allergic, dermatological, hepatic (healthy control subjects only), renal, hematological, pulmonary, cardiovascular, gastrointestinal, neurological, or psychiatric disorder (as determined by the Investigator, Sponsor, and/or Sponsor's representative);
- Any non-hepatic disease or condition that could affect safety or data interpretation (as determined by the Investigator, Sponsor, and/or Sponsor's representative);
- History of significant hypersensitivity, intolerance, or allergy to any drug compound, including cidofovir (CDV), food, or other substance, unless approved by the Investigator, Sponsor, and/or Sponsor's representative;
- History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs except that appendectomy and/or hernia repair will be allowed;
- History of any condition possibly affecting drug absorption (e.g., gastrectomy, active peptic ulcer) within the last 3 months;
- serum albumin \<3 g/dL;
- History or presence of an abnormal ECG, which, in the opinion of the Investigator, Sponsor, and/or Sponsor's representative, is clinically significant;
- History of alcoholism or drug addiction within 1 year prior to Check-in (healthy control subjects only);
- Use of any tobacco- or nicotine-containing products within 6 months prior to Check-in (healthy control subjects only);
- Participation in any other investigational study drug trial in which receipt of an investigational study drug occurred within 30 days (or 5 half-lives, whichever is longer) prior to Check-in;
- Use of oral, implantable, injectable, or transdermal contraceptives within 14 days prior to Check-in (female subjects only);
- For healthy control subjects, use of any prescription medications/products within 14 days prior to Check-in, unless deemed acceptable by the Investigator and Sponsor;
- For healthy control subjects, use of any over-the-counter (OTC), non-prescription preparations (including vitamins, minerals, and phytotherapeutic/ herbal/plant-derived preparations) within 7 days prior to Check-in, unless deemed acceptable by the Investigator, Sponsor, and/or Sponsor's representative;
- Use of alcohol-, grapefruit-, or caffeine-containing foods or beverages within 72 hours prior to Check-in, unless deemed acceptable by the Investigator, Sponsor, and/or Sponsor's representative;
- Poor peripheral venous access;
- Donation of blood during the period of 30 days prior to Screening or donation of plasma during the period of 2 weeks prior to Screening;
- Receipt of blood products within 2 months prior to Check-in;
- Any acute or chronic non-hepatic condition that, in the opinion of the Investigator, Sponsor, and/or Sponsor's representative, would limit the subject's ability to complete and/or participate in this clinical study;
- History of liver transplant;
- History of febrile illness within 5 days prior to dosing.
