入选标准

  • Participants are eligible to be included in the study only if all of the
  • following criteria apply:
  • 1. Participant must be 18 to 50 years of age inclusive, at the time of signing
  • the informed consent.
  • Type of Participant and Disease Characteristics
  • 2. Participants who are overtly healthy as determined by medical evaluation
  • including medical history, physical examination, laboratory tests, ECGs and
  • vital signs.
  • 3. Participants who responded positive to histamine skin prick test and
  • negative to saline injection at screening.
  • 4. Participants with Fitzpatrick skin type I-II (Caucasian).
  • 5. Body weight *50 kg and body mass index (BMI) within the range 19*29.9 kg/m2
  • (inclusive).
  • Sex and Contraceptive/Barrier Requirements
  • 6. Male participants are eligible to participate in the study
  • - A female participant is eligible to participate if she is not pregnant or
  • breastfeeding, and one of the following conditions applies:
  • o Is a woman of non-childbearing potential (WONCBP) as defined in Section 10.4
  • of the protocol: Contraceptive and Barrier Guidance.
  • o Is a WOCBP and using a contraceptive method that is highly effective, with a
  • failure rate of <1%, as described in Section 10.4 of the protocol during the
  • intervention period. The investigator should evaluate potential for
  • contraceptive method failure (e.g., noncompliance, recently initiated) in
  • relationship to the first challenge.
  • - A sensitive pregnancy test is required to be negative on the day of each
  • This pregnancy test is able to detect a pregnancy near the threshold of
  • implantation, correlating with the earliest point of potential exposure. Due to
  • the short half-life of the interventions, a negative highly sensitive pregnancy
  • test as scheduled in the protocol mitigates the risk of pregnancy exposure
  • because exposure will be completely gone even with a worst case but unlikely
  • scenario of conception occurring near the time of dosing. See Protocol Section
  • 8.2.5 Pregnancy Testing
  • - If a urine test cannot be confirmed as negative (e.g., an ambiguous result),
  • a serum pregnancy test is required. In such cases, the participant must be
  • excluded from participation if the serum pregnancy result is positive.
  • - Additional requirements for pregnancy testing during and after study
  • intervention is located in Protocol Section 8.2.5 .
  • - The investigator is responsible for review of medical history, menstrual
  • history, and recent sexual activity to decrease the risk for inclusion of a
  • woman with an early undetected pregnancy
  • Informed Consent
  • 7. Capable of giving signed informed consent as described in Appendix 1 of the
  • protocol which includes compliance with the requirements and restrictions
  • listed in the informed consent form (ICF) and in this protocol.

排除标准

  • Participants are excluded from the study if any of the following criteria apply:
  • Medical Conditions
  • 1. Significant history of or current, cardiovascular (including hypotension,
  • severe hypertension, vasomotor instability), respiratory (including asthma),
  • renal, gastrointestinal, endocrine, haematological, infectious or neurological
  • disorders constituting a risk when taking part in the study or interfering with
  • the interpretation of data.
  • 2. History or presence of significant skin disorder (such as but not limited to
  • chronic urticaria, atopic dermatitis, severe eczema, psoriasis or skin cancer).
  • 3. History of risk for or actual experience of complications from skin biopsy
  • including excess bleeding, infection, or scarring/keloid formation.
  • 4. Abnormal blood pressure as determined by the investigator.
  • 5. Alanine transaminase (ALT) >1.5x upper limit of normal (ULN).
  • 6. Total bilirubin >1.5xULN (isolated bilirubin >1.5xULN is acceptable if total
  • bilirubin is fractionated and direct bilirubin <35%).
  • 7. Current or chronic history of liver disease, or known hepatic or biliary
  • abnormalities (with the exception of Gilbert's syndrome or asymptomatic
  • gallstones).
  • 8. QT interval corrected for heart rate according to Fridericia*s formula
  • (QTcF) >450 msec, based on the mean of triplicate ECGs .
  • NOTE: The QTc is the QT interval corrected for heart rate according to
  • Fridericia*s formula (QTcF).
  • Prior/Concomitant Therapy
  • 9. Use of any form of H1 or H2 antihistamine, tricyclic antidepressants, beta2
  • agonists, dopamine, or beta blocking agents within 14 days before the first
  • challenge visit through final assessments.
  • 10. Use of topical medications such as but not limited to retinoids, steroids,
  • and transdermal hormone replacement therapies on or near the intended site of
  • application within 8 weeks prior to dosing through treatment follow up. Use of
  • other topical preparations such as those containing vitamins, supplements or
  • herbal within 2 weeks prior to dosing through treatment follow up.
  • 11. Past or intended use of any other non-topical over-the-counter or
  • prescription medication, including herbal medications, within 7 days before the
  • first challenge visit, unless, in the opinion of the investigator and GSK
  • Medical Monitor, the medication will not constitute a risk when taking the
  • study intervention or interfere with the interpretation of data.
  • Prior/Concurrent Clinical Study Experience
  • 12. Participation in the study would result in loss of blood or blood products
  • in excess of 500 mL within 3 months.
  • 13. Current enrolment in any clinical study involving an investigational study
  • intervention or any other type of medical research.
  • 14. Current enrolment or past participation in this study.
  • Diagnostic assessments
  • 15. Presence of Hepatitis B surface antigen (HBsAg) or hepatitis B core
  • antibody (HbcAb) at screening or within 3 months before the first challenge day.
  • 16. Positive Hepatitis C antibody test result at screening or within 3 months
  • before the first challenge day.
  • NOTE: Subjects with positive Hepatitis C antibody due to prior resolved disease
  • can be enrolled, only if a confirmatory negative Hepatitis C RNA test is
  • 17. Positive Hepatitis C RNA test result at screening or within 3 months before
