Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

    • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   44338   clinical trials with a EudraCT protocol, of which   7368   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Using an established model of human typhoid infection, whereby healthy adults are deliberately infected with typhoid-causing bacteria, we will determine how effective a new oral typhoid vaccine (M01ZH09) is in preventing infection. A previously licensed oral typhoid vaccine (Ty21a) will be used to make sure the challenge model used works properly.
    E.2.2Secondary objectives of the trial
    1) To compare the clinical and laboratory features of the response to typhoid infection in participants who have previously been vaccinated with M01ZH09, vaccine-placebo or Ty21a. These features will include the course of the illness, the point at which participants may develop typhoid bloodstream infection, and the level of inflammation produced in response to infection. 2) To compare the response of the immune systems to typhoid infection in participants who have previously been vaccinated with M01ZH09, vaccine-placebo or Ty21a. 3)To assess the safety and side-effects of the novel vaccine (M01ZH09) and to compare these with the other two groups (those receiving vaccine-placebo and those receiving the Ty21a vaccine). 4) To develop new methods for diagnosing typhoid infection, which are currently poor. 5) To explore how the genetic response (which protein encoding-genes within the participants DNA are switched on and off) to vaccination in the three groups varies.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Participant is willing and able to give informed consent for participation after the nature of the study has been explained. 2. Male or female, aged 18-60 years inclusive. 3. In good health as determined by medical history, history-directed physical examination and the clinical judgment of the investigators. 4. Female participants of child bearing potential must be willing to ensure that they or their partner use effective contraception for one month prior to challenge and continue to do so until a negative stool sample has been obtained at least 3 months after completion of antibiotic treatment. 5. Able and willing (in the Investigator’s opinion) to comply with all study requirements, including the capacity for good personal hygiene. 6. Willing to allow his or her General Practitioner and consultant, if appropriate, to be notified of participation in the study. 7.

For those involved in provision of health or social care to vulnerable groups only – willing to allow his or her employer to be notified of participation in the study. 9. Willing to give his or her contacts (defined as someone who is likely to have been exposed to the excreta of a challenged participant, usually a household or sexual contact) letters informing them of the participants involvement in the study and offering the contact screening for Salmonella Typhi carriage. 10. Agree to refrain from future blood donation. 11. Be willing to have 24-hr contact with study staff during the four weeks post-challenge.

Contra-indication to taking ciprofloxacin, β-lactam antibiotics, or trimethoprim/sulfamethoxazole. 9. Female participant who is pregnant, lactating or who is unwilling to ensure that they or their partner use effective contraception for one month prior to challenge and continue to do so until a negative stool sample, a minimum of 3 months after completion of antibiotic treatment, has been obtained. 10. Current occupation involving clinical or social work involving direct contact with: a)young children (those attending pre-school groups, nursery or under the age of 2 years) b)highly susceptible patients or persons in whom typhoid infectious would have particularly serious consequences, including the elderly (unless willing not to work until demonstrated to not be infected with Salmonella Typhi in accordance with guidance from the Health Protection Agency). 11. Current occupation as a commercial food handler (involving preparing or serving unwrapped foods not subjected to further heating). 12. Household contact under 2 years of age or who is immunocompromised by treatment or disease. 13. Have elective surgery or other procedures requiring general anaesthesia scheduled during the vaccine/challenge period, at time of enrollment. 14. Have participated in another research study involving an IMP that might affect risk of typhoid infection or compromise the integrity of the study within the 30 days prior to enrolment (e.g. significant volumes of blood already taken in previous study) as assessed by both participant questioning and the TOPS Over Volunteering Prevention System database. 15. Have donated blood in the preceeding 3 months (temporary exclusion only). 16. Have received blood, blood products and/or plasma derivatives or any parenteral immunoglobulin preparation in the past 3 months. 17. Have any other significant disease or disorder which, in the opinion of the investigators, may either put the participants at risk because of participation in the study, or may influence the result of the study, or the participant’s ability to participate in the study.
