纳入标准:
Agree to remain an inpatient for at least seven days after challenge, and until they have no virus shedding,* determined by qualitative RT-PCR for a minimum of two consecutive days post-challenge.
Healthy* males and non-pregnant, non-breastfeeding females**, aged >/= 18 and </=49 years of age, inclusive, at enrollment.
*Good health is defined in inclusion criteria 10.
Women of childbearing potential* must agree to use or have practiced true abstinence** or use at least 1 acceptable primary form of contraception***,****.
These criteria are applicable to females in a heterosexual relationship and child-bearing potential (ie, the criteria do not apply to subjects in a same sex relationship).
*Not of child bearing potential - post-menopausal females (defined as having a history of amenorrhea for at least one year) or a documented status as being surgically sterile (hysterectomy, bilateral oophorectomy, tubal ligation/salpingectomy, or Essure(R) placement with history of documented radiological confirmation test at least 90 days after the procedure).
**True abstinence is 100% of time no sexual intercourse (male's penis enters the female's vagina). (Periodic abstinence [eg calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception).
***Acceptable forms of primary contraception include monogamous relationship with a vasectomized partner who has been vasectomized for180 days or more prior to the subject receiving the influenza challenge virus, intrauterine devices, birth control pills, and injectable/implantable/insertable hormonal birth control products.
****Must use at least one acceptable primary form of contraception for at least 30 days prior to admission and at least one acceptable primary form of contraception during the remainder of the study.
Non-habitual smoker* of tobacco, e-cigarettes or marijuana.
*Non-habitual smokers are those who smoke no more than four cigarettes, other tobacco products, e-cigarettes or marijuana in a week for more than three months and agree not to smoke cigarettes, other tobacco products, e-cigarettes and/or marijuana products during participation in the study.
No self-reported or known history of alcoholism or drug use within the last 30 days and agrees to abstain from alcohol and drugs* for at least one week before admission and throughout the inpatient period.
*Including forms of marijuana not included in criterion 6.
Agree not to use the listed* prescription or over-the-counter medications within 7 days prior to inpatient stay and through inpatient stay, unless approved by the investigator.
*Oseltamivir, zanamivir, peramivir, baloxavir marboxil, amantadine (generic) and rimantadine (Flumadine and generic), aspirin, intranasal steroids, decongestants, antihistamines, and other non-steroidal anti-inflammatory drugs (NSAIDs).
In good health* and not have clinically significant medical, psychiatric, chronic or intermittent health conditions including those listed in the Subject Exclusion Criteria.
*Good health, as determined by medical history, medication use and physical examination to evaluate ongoing chronic medical or psychiatric diagnoses or conditions, defined as those that have been present for at least 90 days, which would not affect the assessment of the safety of subjects or the immunogenicity of challenge. These medical diagnoses or conditions should be stable for the last 90 days (no hospitalizations, emergency room (ER) or urgent care for condition (excluding musculoskeletal conditions) and not listed in the Subject Exclusion Criteria. Subjects may be on medications only if the condition or disease is stable and not deteriorating, if the medical intervention (such as device or medication) was not available during the maximal inpatient period of time, medications are not listed in the Subject Exclusion Criteria and pose no additional risk to subject safety or assessment of adverse events. This also includes no change in prescription medication, dose or frequency as a result of new symptoms or deterioration of the medical diagnosis or condition in the 90 days prior to enrollment. Any prescription change that is due to change of health care provider, insurance company, etc., or that is done for financial reasons, as long as in the same class of medication, will not be considered a deviation of this inclusion criterion. Any change in prescription medication due to improvement of a disease outcome (eg, lowering of the dosage or frequency), as determined by the site principal investigator (PI) or designated clinician licensed to make medical diagnoses and listed on Form FDA 1572, will not be considered a deviation of this inclusion criterion.
Does not have an ongoing symptomatic condition* for which subject has had or has ongoing medical investigations but has not yet received a diagnosis or treatment plan.
*eg, ongoing fatigue without a diagnosis for symptom.
Other screening tests (ECG and CXR) are within normal reference range or not deemed clinically significant by the PI or appropriate sub-investigator*.
*Designated clinician licensed to make medical diagnoses and listed on the Form FDA 1572.
排除标准:
Presence of self-reported or medically documented significant medical or psychiatric condition(s)*.
*Significant medical or psychiatric conditions include but are not limited to:
Presence of immunosuppression or any medications that may be associated with impaired immune responsiveness*.
*Including, but not limited to, corticosteroids exceeding 10 mg/day of prednisone equivalent, allergy injections, immunoglobulin, interferon, immunomodulators, cytotoxic drugs, or systemic corticosteroids or other similar or toxic drugs during the preceding 12-month period prior to screening. Low dose topical and intranasal steroid preparations used for a discrete period of time are permitted.
Significant abnormality altering the anatomy of the nose/nasopharynx* clinically significant nasal deviation, or nasal/sinus surgery within 180 days prior to challenge.
*Including significant nasal polyps.

官方标题ICMJE | 在健康受试者中,对流感A/Bethesda/MM2/H1N1病毒的受控人类感染研究(A/California/04/2009/H1N1样病毒)评估免疫对症状流感病毒感染的影响的影响 |
简要摘要 | 这是对反向设计的良好制造实践(GMP)级,抗病毒敏感的,流感A/Bethesda/MM2/H1N1病毒(A/California/04/2009/H1N1类似)感染以评估评估以评估评估的影响的影响的研究对临床和免疫反应的免疫力预先存在。多达80名健康的成年受试者将通过A/Bethesda/MM2/H1N1病毒进行鼻内接种,其临床表现,病毒脱落和免疫学反应将被表征。这项研究的主要目的是评估有症状的逆转录 - 聚合酶链反应(RT-PCR)阳性流感病毒感染和现有的hemagglutin抑制测试(HAI)抗体抗体滴度的关联。 |
详细说明 | 这是对反向设计的良好制造实践(GMP)级,抗病毒敏感的,流感A/Bethesda/MM2/H1N1病毒(A/California/04/2009/H1N1类似)感染以评估评估以评估评估的影响的影响的研究对临床和免疫反应的免疫力预先存在。多达80名健康的成年受试者将通过A/Bethesda/MM2/H1N1病毒进行鼻内接种,其临床表现,病毒脱落和免疫学反应将被表征。这项拟议的研究将在美国国家过敏和传染病研究所(NIAID)微生物学和传染病(DMID)发起的疫苗和治疗评估单位(VTEU)临床研究现场建立H1N1流感病毒控制的人类感染(CHI)模型(CHI)模型。该模型已被壁内研究的NIAID分割开发和使用。拟议的研究将扩大美国的研究能力,以进行流感chi研究,以促进对流感发病机理和新型疫苗研发的理解。这项研究的主要目的是评估有症状的逆转录 - 聚合酶链反应(RT-PCR)阳性流感病毒感染和现有的hemagglutin抑制测试(HAI)抗体抗体滴度的关联。这项研究的次要目标是:1)通过定量RT-PCR从基线和挑战后的研究对象中描述病毒恢复; 2)描述在健康受试者中通过感染状态在挑战后的血清HAI和MN抗体反应; 3)评估无症状的RT-PCR阳性流感病毒感染(病毒脱落)挑战后和先前存在的HAI抗体滴度的关联; 4)评估挑战后和先前存在的HAI抗体滴度的有症状的RT-PCR阴性状态的关联; 5)确定挑战后严重不良事件(SAE)的频率。 |
