    to show a 14 Relative Risk Reduction.
  • MRC have also awarded an extra years funding

  • Recruitment was temporarily suspended in UK,
    Europe and Argentina in Jan 2006
  • Until compliance with new documentation
    requirements for good manufacturing practice
  • Not because of any safety issue with the Scottish
    IVIG product

11
  • Recruitment recommenced 24 March in UK, Europe
    and Argentina
  • Argentina have 21 centres
  • Estimated contribution of 50 babies per month

12
1 year follow up
  • Important to maintain contact with families at 1
    year to maximize the 2 year follow up rate
  • 490 babies have reached 1 year corrected for
    gestation
  • 452 babies have complete data
  • 37 have data pending
  • 1 is presumed lost to follow up

13
2 year Follow up
  • ANZ sites
  • 205 babies surviving babies have reached 2 years
    corrected for gestation
  • Currently 180 (88) have complete data
  • 24 have appointments pending
  • 1 is lost (? Moved to Samoa)
  • Expected rate of 2 year follow up is 99

14
MRC extension funding application
  • UK MRC has funded an extra years funding for UK/
    European and Australian sites.
  • This will extend recruitment in Australia until
    mid or late 2007

15
Revised sample size
16
Neonatal sepsis, inflammation and
anti-inflammatory therapies
  • Neonatal inflammation is an important determinant
    of white matter damage
  • IVIG has multiple immuno-modulatory properties
  • IVIG is an important candidate as an
    anti-inflammatory therapy in neonatal sepsis

17
Reviews of the evidence that perinatal
inflammation predisposes to neonatal brain damage
  • Inflammation and preterm birth
  • John Newnham
  • Inflammation and the developing human brain
  • Don Peebles
  • Antenatal inflammation consequences for neonatal
    immunology
  • Alan Jobe

18
  • Can a 500 g baby mount an over-inflammatory
    response?

19
YES, plasma TNF level gt 1000 pg/ml
20
  • INIS is addressing a major research question
  • Does IVIG reduce mortality and morbidity in
    infants with suspected or proven neonatal
    infection?

21
A CONSENT DVD DESIGNED TO IMPROVE CONSENT UPTAKE
TO RANDOMISED CONTROLLED TRIALS IN
NEONATOLOGYA PILOT STUDY IN THE INIS NETWORK
  • Priya Duggal-Beri, Phyllis Butow, Wendy Hague ,
    Val Gebski, Lorraine ORegan, William
    Tarnow-Mordi on behalf of the
  • International Neonatal Immunotherapy Study (INIS)
    Collaborative Group.

22
Barriers to participation in randomised
controlled trials a systematic review.Ross et
al 1999
  • Clinician barriers included
  • time constraints
  • lack of staff and training
  • worry about the impact on the doctor-patient
    relationship
  • concern for patients
  • loss of professional autonomy
  • difficulty with the consent procedure
  • lack of rewards and recognition
  • insufficiently interesting question.

23
  • Patient barriers included
  • additional demands of the trial
  • patient preferences
  • worry caused by uncertainty
  • concerns about information and consent.

24
  • There is no evidence on the impact of Digital
    Video Decoders (DVDs) or videos on knowledge or
    confidence of staff in obtaining consent, and on
    uptake of consent by parents.
  • We explored the effectiveness of a DVD/ video and
    accompanying booklet in 24 INIS sites in
  • describing consent delivery methods
  • improving knowledge about the INIS trial.

25
VINIS Video/ DVD Booklet site intervention
study
  • A pilot RCT in 24 ANZ INIS sites to explore
  • whether a video and booklet for staff who seek
    consent can improve their knowledge and
    confidence
  • its potential effect on recruitment rate.
  • 1645 Wednesday 5th April
  • Level 2 Meeting Room 11

26
Data Collection issues
  • Excellent rate of completion and accuracy of CRFs
  • Consent forms
  • Please ensure that all signatures by parents and
    investigators and witnesses are complete
  • HIC consent forms
  • Please remember to ask new and old parents to
    complete this consent form (for economic
    analysis)
  • Days of respiratory support after INIS
    intervention
  • Please include all days the baby received any
    respiratory support in your hospital
