入选标准

  • 1. Subjects with a diagnosis of moderate to severe plaque psoriasis for at least 12 months before the first dose of study medication, who are otherwise healthy.
  • Diagnosis of moderate to severe plaque psoriasis:
  • Psoriasis plaques cover =10% of body surface area.
  • PASI score of =12, and PGA score of =3, and suitable for systemic or light therapy.
  • Cohort B only: Identification of a target lesion (=2 cm²) on the trunk or extremities. The target lesion will be used for skin biopsies. Lesions on palms, soles, knees, elbows and intertriginous areas will not be used as the target lesion site.
  • Subjects with psoriasis and concomitant joint involvement (psoriatic arthritis) only: Subjects who have had a diagnosis of active psoriatic arthritis will be included in the exploratory assessment of the effect of GSK2586184 on their joint disease using the ACR response criteria. Otherwise healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the investigator agrees that the finding is unlikely to introduce
  • additional risk factors and will not interfere with the study procedures. Specific laboratory parameter exclusion criteria are listed in Section 4.2.2 of the protocol.
  • 2. Male or female, between 18 and 75 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;
  • 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 (<147 pmol/L) is confirmatory).
  • Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use acceptable contraception methods, as listed in Section 7.1 of the protocol, if they wish to continue their HRT during the study.
  • Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment. For most forms of HRT, at least 2-4 weeks should 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.
  • Child-bearing potential and agrees to use acceptable contraception methods, as listed in Section 7.1 of the protocol, for at least 1 month before the start of dosing to sufficiently minimise the risk of pregnancy at that point. Female subjects must agree to use contraception until at least 2 weeks after their last dose.
  • 4. Subjects must agree to use UV light protection as described in Section 7.3 of the protocol.
  • 5. Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 58
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 6

排除标准

  • 1. Unable to refrain from the use of the following prescription and non-prescription drugs from the following periods before the first dose of study medication until completion of the follow-up visit:
  • 12 weeks: alefacept, ustekinumab, adalimumab, etanercept, infliximab, or certolizumab pegol
  • 4 weeks or 5 half-lives, whichever is longer:
  • systemic medications for other medical conditions that are known to affect psoriasis, including but not limited to oral corticosteroids, cyclosporine, methotrexate, lithium, and beta-adrenergic blockers
  • 7 days or 5 half-lives:
  • statins and other OATP and BCRP sensitive substrates (e.g. rapaglinide)
  • any agent known to be a substrate of MATE1 and MATE2-K, which undergoes significant renal secretion (e.g. cimetidine)
  • 3 weeks or 5 half-lives whichever is longer:
  • any agent known to be a strong CYP3A4 inhibitor or inducer
  • 2 weeks: topical therapies that are known to affect psoriasis, including but not limited to corticosteroids, retinoids, vitamin D derivatives, tar and anthralin. Other medications will be considered on a case-by-case basis, and will be allowed if in the opinion of the investigator the medication will not interfere with the study procedures or compromise subject safety.
  • 2. Phototherapy within 4 weeks before the first dose of study medication.
  • 3. A live vaccination within 4 weeks before the first dose of study medication, or a live vaccination planned during the course of the study (until completion of the follow-up visit).
  • 4. A major organ transplant (e.g. heart, lung, kidney, liver) or haematopoietic stem cell/marrow transplant.
  • 5. Significant unstable or uncontrolled acute or chronic disease unrelated to psoriasis which, in the opinion of the investigator, could confound the results of the study or put the subject at undue risk. View protocol for further information.
  • 6. A planned surgical procedure that, in the opinion of the investigator, makes the subject unsuitable for the study.
  • 7. A history of malignant neoplasm within the last 5 years, except for adequately treated cancers of the skin (basal or squamous cell) or carcinoma in situ of the uterine cervix.
  • 8. Acute or chronic infections, as follows:
  • Known previous or active infection with Mycobacterium Tuberculosis
  • Currently on any suppressive therapy for a chronic infection (such as pneumocystis, cytomegalovirus, herpes simplex virus, herpes zoster and atypical mycobacteria).
  • Hospitalisation for treatment of infection within 60 days before first dose.
  • Use of parenteral (IV or intramuscular) antibiotics (antibacterials,
  • antivirals, antifungals, or antiparasitic agents) within 60 days before
  • first dose.
  • 9. Unable to refrain from the consumption of grapefruit or grapefruit
  • juice from 3 weeks before the first dose of study medication until 2
  • weeks after the last dose of study medication.
  • 10. History of sensitivity to any components of the study medications, or a history of drug or other allergy that, in the opinion of the investigator, contraindicates their participation.
  • 11. Serologic evidence of Hepatitis B (HB) infection based on the results of testing for HBsAg, anti-HBc antibody. View protocol for further information.
  • 12. Positive test for Hepatitis C antibody confirmed on the same sample with a Hepatitis C RIBA immunoblot assay or equivalent test. Please view protocol for further information.
  • 13. A positive test for HIV antibody.
  • 14. Pregnant females as determined by a positive ser
