Trial overview
Official title: A Repeat-Dose, Open-Label, Parallel-Group Study to Assess the Pharmacokinetics of GSK1278863 and Metabolites in Subjects with End Stage Renal Disease Undergoing Peritoneal Dialysis
Trial description: GSK1278863 is an orally-active, novel small molecule agent which inhibits hypoxia-inducible factor (HIF) prolyl -4- hydroxylases (PHDs) and is in development for the treatment of anaemia associated with chronic kidney disease (CKD). As the kidney represents a major site of elimination for many drugs and their metabolites, and GSK1278863 will be administered to subjects with various stages of renal disease, it is important to characterize the pharmacokinetics in this target patient population. The purpose of this study is to characterize the pharmacokinetics of GSK1278863 and its metabolites in subjects with end stage renal disease (ESRD) undergoing peritoneal dialysis. This will be a repeat-dose, open-label, parallel-group study. Approximately 30 subjects with ESRD will be enrolled in two cohorts (15 subjects in each cohort) to ensure that 6 subjects on continuous ambulatory peritoneal dialysis (CAPD) (cohort 1) and 6 subjects on automated peritoneal dialysis APD (cohort 2) complete dosing and critical assessments. GSK1278863 will be administered once daily for 14 days. Primary pharmacokinetic assessments will be made on Days 1 and 14.

- SAFETY:
- Satisfactory medical evaluation based upon medical history, medication history, physical examination, and clinical laboratory data obtained at the Screening visit. The determination of clinical significance will be made by the Investigator and the GlaxoSmithKline (GSK) Medical Monitor and will require that the finding is unlikely to introduce additional risk factors or interfere with the study procedures, or the integrity of the study.
- SAFETY
- A positive test for Human Immunodeficiency Virus (HIV) antibody.
Inclusion and exclusion criteria
Inclusion criteria:
- SAFETY:
- Satisfactory medical evaluation based upon medical history, medication history, physical examination, and clinical laboratory data obtained at the Screening visit. The determination of clinical significance will be made by the Investigator and the GlaxoSmithKline (GSK) Medical Monitor and will require that the finding is unlikely to introduce additional risk factors or interfere with the study procedures, or the integrity of the study.
- Corrected QT interval (QTc) <470 milliseconds (msec) OR QTc <480 msec in subjects with Bundle Branch Block. These should be based on average of triplicate values obtained over a brief recording period at Screening and on Day -1 and the single reading on Day 17. The same QT correction formula should be used to determine inclusion and discontinuation for any individual subject throughout the study.
- Vitamin B12 and folate above the lower limit of normal at Screening.
- Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), and bilirubin <=1.5 x upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). EFFICACY:
- A subject is eligible to enroll and participate in this study if he/she has ESRD and is on peritoneal dialysis for at least 2 months with an average urine output of <750 mL/daily with a combined weekly (urine and peritoneal dialysis output) Kt/V urea >1.7 measured at any time within last 3 months.
- No history of peritoneal dialysis-associated peritonitis, peritoneal catheter tunnel (exit site) infection or leakage for at least 3 months before study.
- Meets the following erythropoiesis stimulating agent (ESA) criteria: Is ESA naive (i.e., no ESA use within the previous 12 weeks of screening) OR agrees to discontinue ESA (if currently using ESA) for at least 7 days prior to first dose of GSK1278863 until completion of Follow-up visit (If the subject has a scheduled ESA interval which is <=7 days, ESA treatment must be discontinued for at least 7 days prior to first dose of GSK1278863. If the subject has a scheduled ESA interval which is >7 days, ESA treatment must be discontinued for at least the scheduled interval length [e.g., if ESA interval is 14 days, then ESA must be discontinued for >=14 days] prior to the first dose of GSK1278863)
- Has a haemoglobin value: For ESA naïve subjects: <10.0 g/dL (UK site(s) only: <=11.0 g/dL); For subjects receiving ongoing ESA treatment: <=11.0 g/dL at Screening (UK site(s) only: <=12.0 g/dL at Screening). OTHER:
- Subjects who are >=18 years of age at the time of Screening.
- A female subject is eligible to participate if she is of: (a) Childbearing potential, and agrees to use one of the contraception methods described in the protocol. This criterion must be followed from the time of Screening until completion of the Follow-up Visit; (b) 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) 23.0-116.3 international units (IU)/litre (L) and estradiol <=10 picograms (pg)/mL (or <=37 picomoles [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 months must 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.
- Body weight >45 kilograms (kg) and <140 kg at Screening.
- The subject is mentally and legally able to comply with the requirements and restrictions of the protocol and has provided signed informed consent prior to participation in any protocol-specific procedures, including Screening procedures.

Examples of conditions that could interfere with normal gastrointestinal anatomy or motility include gastrointestinal bypass surgery, partial or total gastrectomy, small bowel resection, vagotomy, malabsorption, Crohn’s disease, ulcerative colitis, or celiac sprue. Examples of conditions that could interfere with hepatic function include Gilbert’s syndrome.
- Evidence of active peptic, duodenal or esophageal ulcer disease at Screening OR history of clinically significant gastro-intestinal (GI) bleeding within 3 months prior to Screening.

- Consumption of red wine, grapefruit (juice), blood orange (juice), star fruit, onions, kale, broccoli, green beans, or apples from 7 days prior to the first dose of investigational product until the Follow-up visit, unless in the opinion of the Investigator and GSK Medical Monitor this will not interfere with the study procedures and compromise subject safety.
- Use or planned use of any prescription or non-prescription drugs that are prohibited within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of GSK1278863 until completion of the follow-up visit, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
- The following medications are specifically prohibited for the duration of the study (from Screening to the follow-up visit at the end of the study): Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) with the exception of low dose (<=325 mg/day) aspirin/acetylsalicylic acid. Occasional NSAID use is permitted; Immunosuppressant drugs and drugs used to treat malignancies (including corticosteroids at doses >10 mg prednisolone per day or equivalent) within 2 weeks of first dose of GSK1278863.

A positive pre-dosing screen for medications that are prescribed to a renal subject for pre-existing condition(s), may be allowed if in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
- 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 (approximately240 mL) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits.
- History of regular use within 6 months of the study of tobacco- or nicotine-containing products in excess of 20 cigarettes per day or equivalent.
