简要总结

This study is the first study with GSK2982772, a receptor-interacting protein-1 (RIP1) kinase inhibitor, in subjects with moderate to severe RA who are currently being treated with disease modifying anti-rheumatic drugs (DMARDs). The primary objective of the study is to investigate the safety and tolerability of repeat oral doses of GSK2982772 in subjects with moderate to severe RA. In addition to the PK, a number of experimental and clinical endpoints will be employed to obtain information on the PD, and preliminary efficacy in subjects with active RA. Although no formal hypothesis will be tested, these endpoints will enable a broader understanding of the mechanism of action and potential for clinical efficacy of GSK2982772 in RA. After a screening period of up to 30 days, approximately 24 subjects will be randomized to receive either GSK2982772 or placebo for 84 days (12 weeks), followed by a follow-up period (28 days). The total duration of participation in the study will be approximately 20 weeks from screening to the last study visit.

•Subject must have received at least 12 weeks of non-biologic DMARD monotherapy or MTX/DMARD combination therapy prior to screening and must be on stable dose throughout the study.
•Subject is naive to any biological therapies for RA or subject may have had previous exposure to a single anti-tumor necrosis factor (TNF) biologic agent which was discontinued for reasons other than primary non-response more than 8 weeks (or 5 half lives whichever is longer) from first dose.
•For subjects who have consented to synovial joint biopsy:
•Subject has an involved knee, wrist, or ankle suitable for biopsy, as assessed by a rheumatologist at screening.
•A body mass index (BMI) within range of 18.5 - 35 kilogram/meter^2 (Kg/m^2) (inclusive) at screening.
•Male and female subjects Males: Male subjects with female partners of child bearing potential must comply with the contraception requirements specified in the protocol.
•Females: A female subject is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotropin [HCG] test), not lactating, and at least one of the following conditions applies:
•Non-reproductive potential as defined as pre-menopausal females with either documented tubal ligation or Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion or Hysterectomy or Documented Bilateral Oophorectomy. For Postmenopausal females as 12 months of spontaneous amenorrhea in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) and estradiol levels consistent with menopause.

•An active infection, or a history of infections as follows:
•Hospitalization for treatment of infection within 60 days before first dose (Day 1).
•Currently on any suppressive therapy for a chronic infection (such as pneumocystis, cytomegalovirus, herpes simplex virus, herpes zoster and atypical mycobacteria).
•Use of parenteral (intravenous [IV] or intramuscular) antibiotics (antibacterials, antivirals, antifungals, or antiparasitic agents) for an infection within 60 days before first dose.
•A history of opportunistic infections within 1 year of screening (e.g. pneumocystis jirovecii, cytomegalovirus [CMV] pneumonitis, aspergillosis). This does not include infections that may occur in immunocompetent individuals, such as fungal nail infections or vaginal candidiasis, unless it is of an unusual severity or recurrent nature.

•History of Tuberculosis (TB), irrespective of treatment status.
•A positive diagnostic TB test at screening defined as a positive QuantiFERON-TB Gold test or T-spot test. In cases where the QuantiFERON or T-spot test is indeterminate, the subject may have the test repeated once, but they will not be eligible for the study unless the second test is negative. In cases where the QuantiFERON or T-spot test is positive, but a locally-read follow up chest x-ray, shows no evidence of current or previous pulmonary tuberculosis, the subject may be eligible for the study at the discretion of the Investigator and GSK Medical Monitor.

The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined and documented prior to initiation of the study. In other words, several different formulae cannot be used to calculate the QTc for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trial. For purposes of data analysis, QTcB, QTcF, another QT correction formula, or a composite of available values of QTc will be used.

Only those clinical chemistry parameters with PCI values (to low and to high) have been presented.

Number of Participants With Worst Case Any Increase in Urinalysis Results Post-Baseline Relative to Baseline by Dipstick Method

时间窗: Up to Day 112

Urine samples were collected to assess glucose, ketones, occult blood and protein by dipstick method. The dipstick test gave results in a semi-quantitative manner, and results for urinalysis parameters glucose, ketones, occult blood and protein were categorized as 'any increase from Baseline', which imply any increase in their concentrations in the urine sample. Only participants with worst case any increase from Baseline values are presented.

Number of Participants With Worst Case Any Increase in Urinalysis Results Post-Baseline Relative to Baseline by Microscopy Method

时间窗: Up to Day 112

Urine samples were collected to assess glucose, ketones, occult blood and protein by dipstick method. Microscopy was performed only on urine samples showing an abnormality on the dipstick. Microscopy was performed for hyaline casts, red blood cells and white blood cells. Results for microscopy parameters hyaline casts, red blood cells and white blood cells were categorized as 'any increase from Baseline', which imply any increase in their count in the urine sample. Only participants with worst case any increase from Baseline values are presented.
