Trial overview
Official title: A Single Centre, Open-label, 5-Period, Cross over, Randomized Study in Healthy Elderly Subjects to Evaluate the Relative Bioavailability of Hydrobromide Salt and Free Base Immediate Release Tablet Formulations of Danirixin in the Fed State, and to Evaluate the Effect of Food and Gastric Acid Secretion Suppression on Danirixin Pharmacokinetics Following Administration of Hydrobromide Salt Tablets
Trial description: The current study will help to increase our understanding of the pharmacokinetics (PK) of danirixin. The primary objective of the study is to estimate the relative bioavailability of danirixin Hydrobromide (HBr) tablet, when compared to danirixin free base (FB). Safety and tolerability information for oral administration of danrixin HBr tablets in elderly subjects will also be obtained. Secondarily, this study will evaluate effect of food on PK of danirixin HBr, effect of gastric acid suppression, and within-subject PK variability of danirixin HBr. The outcome of this study will contribute to the selection of the most appropriate formulation/dosing regimen for future studies.This is an open-label, 5-period crossover study. Study will be conducted in 18 healthy elderly subjects. Screening will occur within 42 days prior to Day 1 of period 1. The Treatment Periods will be separated by a washout period of a minimum 5 days. Follow-up will be done within 3 to 10 days post last dose.

Accepts healthy volunteers
Yes
- Between 65 and 80 years of age at screening (inclusive)
- Healthy, as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring or a subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included if the investigator and the GlaxoSmithKline (GSK) Medical Monitor agree that the finding is unlikely to introduce risk factors and will not interfere with the study procedures and objectives.
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert’s syndrome or asymptomatic gallstones).
- A positive pre-study Hepatitis B surface antigen (HBsAg) or positive Hepatitis C antibody (HCV Ab) result within 3 months of screening.
Inclusion and exclusion criteria
Inclusion criteria:
- Between 65 and 80 years of age at screening (inclusive)
- Healthy, as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring or a subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included if the investigator and the GlaxoSmithKline (GSK) Medical Monitor agree that the finding is unlikely to introduce risk factors and will not interfere with the study procedures and objectives.
- Body Mass Index between 19 and 34 (inclusive)
- Male or Female Males: Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until a cycle of spermatogenesis following five terminal half- lives after the last dose of study medication. a. Vasectomy with documentation of azoospermia. b. Male condom plus partner use of one of the contraceptive options: Contraceptive subdermal implant, Intrauterine device or intrauterine system, Oral Contraceptive, either combined or progestogen alone Injectable progestogen, Contraceptive vaginal ring, Percutaneous contraceptive patches. This is an all-inclusive list of those methods that meet the following GSK definition of highly effective: having a failure rate of less than 1% per year when used consistently and correctly and, when applicable, in accordance with the product label. For non-product methods (e.g., male sterility), the investigator determines what is consistent and correct use. The GSK definition is based on the definition provided by the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception. Females: A female subject is eligible to participate if she is not pregnant (as confirmed by a negative urine human chorionic gonadotrophin [hCG] test), not lactating, and at least one of the following conditions applies: Non-reproductive potential defined as: a. Pre-menopausal females with one of the following: Documented tubal ligation, Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, Hysterectomy, Documented Bilateral Oophorectomy. b. Postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) and estradiol levels consistent with menopause (refer to laboratory reference ranges for confirmatory levels)]. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods 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 enrolment.
