Detailed Description:
Compound 1278863A is a novel small molecule agent, which stimulates erythropoiesis through inhibition of hypoxia-inducible factor (HIF)-prolyl hydroxylases (EGLNs). This compound is being developed for the treatment of anemia. This study, PHI112843, will be the first administration of 1278863A to investigate the safety, tolerability, pharmacokinetics and/or pharmacodynamics of single oral doses of 50 mg and 150 mg in pre-dialysis subjects with moderate or severe renal impairment and 150 mg in hemodialysis-dependent subjects. Four to eight subjects will complete each dose cohort. Multiple blood samples for pharmacokinetic and/or pharmacodynamic analyses will be obtained post-dose in each cohort. Safety will be assessed by measurement of vital signs, cardiac monitoring, collection of adverse event assessments and laboratory safety tests.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. A male or female is eligible to enroll and participate in this study if he/she:

    • (Part 1) has Moderate to Severe Renal Impairment (equivalent to NKF KDOQI Stage 3 or 4, not receiving dialysis) as determined by estimated Glomerular Filtration Rate (eGFR) calculated by the abbreviated MDRD equation, OR has Normal Renal Function determined by creatinine clearance (CLCR) via the Cockcroft-Gault equation, using serum creatinine and demographic data, obtained at Screening. Subjects with Normal Renal Function should have no greater than trace blood or protein on Screening urinalysis.
    • (Part 2) has severe renal impairment (end-stage renal failure) and has been on stable hemodialysis treatment (three times weekly) for 3 months prior to Screening.
    • otherwise healthy or considered clinically stable with respect to underlying renal impairment as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring.
    • has clinical laboratory test results that are considered clinically stable in the opinion of the Principal Investigator, especially if the clinical abnormality or laboratory parameter is deemed associated with the subject's underlying renal impairment. A normal subject with a clinical abnormality or laboratory parameters outside the reference range may be included only if the Investigator and the Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  2. Male or female between 18 and 65 years of age inclusive, at the time of signing the informed consent.
  3. A female subject is eligible to participate if she is of:

    - Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods described in the protocol if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrollment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT.

    Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.

  4. Male subjects must agree to use one of the contraception methods listed in the protocol. This criterion must be followed from the time of the first dose of study drug until completion of the Follow-up visit.
  5. Body weight greater than or equal to 50 kg and BMI within the range 17 - 33 kg/m2 (inclusive).
  6. AST, ALT, alkaline phosphatase and bilirubin less than or equal to 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
  7. QTcB or QTcF < 450 msec; or QTc < 480 msec in subjects with Bundle Branch Block. These can be based on single ECG value or average of triplicate values obtained over brief recording period.
  8. Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.

Exclusion Criteria:

  1. A hemoglobin value at Screening is:

    • Healthy male subjects or post-menopausal females: > 16.5 g/dL
    • Healthy female subjects: > 15.5 g/dL
    • Renally impaired male or female subjects: <10 g/dL
  2. The values of hematological parameters at Screening, for healthy subjects only, are outside the reference range and clinically significant deemed by the Investigator and Medical Monitor
  3. The values of the following tests at Screening, for healthy subjects only, are:

  5. A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of Screening.
  6. A positive test for HIV antibody.
  7. A positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines. A positive pre-study drug screen, for medications that are prescribed to a subject for pre-existing condition(s), may be allowed if in the opinion of the Investigator and Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
  8. History of drug abuse or dependence within 6 months of the study.
  9. History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 8 g of alcohol: a half-pint (~240 ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits.
