Eligibility
Key inclusion criteria
1. Male or female between 18 and 85 years of age inclusive, at the time of signing the
informed consent.

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

1. (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, and not expected to go
on dialysis until = 8 weeks after first administration of investigational
product. Stage 5, non-dialysis patients with eGFR of 10 15 mL/min per 1.73 m2
will also be eligible for Part 1 on a case-by-case basis.

2. (Part 2) has Severe Renal Impairment and has been on stable hemodialysis
treatment for 1 month prior to Screening (subjects with planned transition to
hemodialysis) or 3 months prior to Screening (subjects emergently placed on
hemodialysis). These subjects are equivalent to NKF KDOQI Stage 5.

3. otherwise healthy or considered clinically stable with respect to underlying
renal impairment and with respect to underlying/chronic disease as determined by
a responsible and experienced physician, based on a medical evaluation including
medical history, physical examination, laboratory tests and cardiac monitoring.

4. 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 patient's underlying renal
impairment.

3. Meets the following erythropoiesis stimulating agent (ESA) criteria:

1. The patient is ESA naïve OR

2. If the patient has a scheduled ESA interval which is = 7 days, ESA treatment must
be discontinued for at least 7 days OR

3. If the patient has a scheduled ESA interval which is > 7 days, ESA treatment must
be discontinued for at least that scheduled interval length (eg discontinued = 14
days for a scheduled 14 day ESA interval) AND The patient will not resume ESA
treatment until completion of the Follow-up Visit (Day 57).

4. Has a hemoglobin value:

1. For ESA naïve patients: =11.0 g/dL

2. For patients receiving ongoing ESA treatment: =11.5 g/dL at Screening with a re
check value of =11.0 g/dL after appropriate ESA discontinuation according to
Inclusion 3 and prior to commencing study drug dosing.

5. 5. Has serum ferritin at Screening:

1. =40 µg/L with the absence of microcytic or hypochromic RBCs (regardless of
transferrin saturation %) OR

2. 25-39 µg/L with transferrin saturation % =20% (fraction saturation =0.20) and the
absence of microcytic or hypochromic RBCs

6. Has Vitamin B12 and folate above the lower limit of normal at Screening

7. A female patient is eligible to participate if she is:

1. of childbearing potential, and must agree to use one of the contraception methods
in Section 8.1.1. This criterion must be followed from the time of Screening
until completion of the Follow-up Visit (Day 57) OR

2. 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 in Section 8.1.1 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.

8. Male patients must agree to use one of the contraception methods listed in Section
8.1.2. This criterion must be followed from the time of the first dose of study drug
until completion of the Follow-up Visit (Day 57).

9. Body weight = 45 kg

10. QTcB or QTcF < 450 msec; or QTc < 480 msec in patients with bundle branch block. These
should be based on an average of triplicate values obtained at Screening.

11. Capable of giving written informed consent, which includes compliance with the
requirements and restrictions listed in the consent form.
Minimum age
18 Years
Maximum age
85 Years
Sex
Both males and females
Can healthy volunteers participate?
