Content
  • General introduction
  • Website
  • Randomization procedure
  • Medication schedule
  • What to do at the occurence of hypertension
  • Prophylactic stress medication
  • Rescue therapy
  • SUSAR procedure
  • Discharge from level III hospital
  • with study medication?
  • BPD diagnosis/Oxygen reduction test

3
Purpose of the study
  • To investigate whether hydrocortisone, initiated
    7-14 d after birth reduces the combined outcome
    death or BPD at 36 wks PMA
  • To investigate whether a potential beneficial
    effect on BPD is not at the cause of
    (inacceptable) adverse effects

4
Inclusion criteria
  • GA lt 30 wks and/or BW lt 1250 g
  • Ventilator dependent between 7-14 days PNA
  • RI (MAwP x FiO2) 3.5
  • RI during gt 12 h/dy and for gt 48 uur
  • Targets SpO2 85-95 / pCO2 of 5.0-7.5 kPa
  • targets only for calculating RI, after inclusion
    according to local protocol!

5
Exclusion criteria
  • Chromosomal defects
  • Major congenital malformations that
  • compromise lung function (SP def., hernia)
  • result in chronic ventilation (e.g. Pierre Robin
    sequence)
  • Congenital cerebral malformations
  • Use of steroids for improving lung function and
    respiratory status prior to inclusion

6
No strict exclusion criteria
  • Sepsis and/or pneumonia
  • Await the effect of antibiotica 48 uur
  • Hemodynamic significant ODB
  • Preferable screening 7 dy and treating according
    to local protocol
  • Attempt not to use indo/ibu en HC simultanuous

7
Randomization
  • Possible between 7-14 days PNA
  • Hydrocortison or placebo 22 dys
  • First dose within 24 hours after inclusion
  • Web-based randomization
  • Stratification according to center and GA
  • Twin may be allocated to the same arm
  • Procedure on the website

Medication
13
HC course
  • Hydrocortison Pharmachemie (100 mg/ml)
  • Cumul. dose 72,5 mg/kg (2.5 mg/kg dexa)
  • 5 mg/kg/d in 4xday during 7 dys
  • 3,75 mg/kg/d in 3xday during 5 dys
  • 2,5 mg/kg/d in 2xday during 5 dys
  • -1,25 mg/kg/d in 1xday during 5 dys
  • Total duration 22 days

14
Placebo course
  • ACE pharmaceuticals Zeewolde, NL
  • Mannitol as base (pH en Osmol identical to HC)
  • Same concentration/dose as HC
  • On the shelf stable for 3 years

15
Study medication
  • Transported via AMC, delivered in badges of 10
    pieces
  • Issue locally by the pharmacy
  • (per patient or per badge)
  • Stock will be automattically suplemented
    according to use
  • Medication kit contains of 23 vials

16
Study medication
  • After randomization a medication order can be
    printed from the website

Study medication
  • Preparation protocol
  • Diluent from own stock
  • Preparation of medication per dag
  • Medication recorded on drug accountability form

Medication schedule

21
Details medication
  • Occurring of hypertension
  • Prophylactic stress medication
  • Go to website/protocol

22
  • Rescue therapy

23
Treatment failure of vroege rescue
  • Reason for considering open label rescue
  • deterioration with RIgt10 for gt6 uur
  • no improvement (RIlt10) and
  • At least 10 dys study medication
  • Attempt to extubate failed lt 24 hrs
  • Rescue with HC according to study schedule and
    stop study medication

24
Late rescue treatment
  • Patient still ventilator dependent after 22 d
  • Attempt to extubate failed
  • Late rescue possible with HC according to study
    protocol

25
Safety and reportingAE/SAE/SUSAR
  • AE Any undesirable experience occurring to a
    subject duringthis trial, whether or not
    considered related to the investigational.
  • An AE is a SAE if
  • Resulted in death
  • Life-threatening
  • Required (prolongation of existing)
    hospitalisation
  • Persistent or significant disability/incapacity
  • Another important medical condition

26
Context-specific SAEs
  • Study population at high risk of serious
    complications,
  • inherent to their vulnerable condition
  • unrelated to the intervention which is under
    evaluation
  • Endpoints of the study in the CRF
  • Immediate reporting of these complications will
    not enhance the safety of this trial
  • Reporting of these events to the DMC and METC on
    a annual basis.

27
Suspected (Unexpected) Serious Adverse Reactions
(SUSAR)
  • SUSAR adverse reactions, of which the nature,
    or severity, is not consistent with the
    applicable product information or the
    context-specific SAEs as listed above.
  • Reporting lt 24 hrs on AE page of CRF and by
    telephone to the PI

29
Web-based Alert procedure
  • Alert Procedure (automated email to
    stop-bpd_at_amc.nl) should be used with
  • Death
  • Simultanuous treatment of indomethacine/ibuprofen
    and study medication
  • Occurrence of solitair gastointestinal
    perforation
  • Occurence of hypertension, as defined in the
    protocol
  • Use of open label hydrocortisone
  • Reporting should be done lt 72 hrs of the
    occurence of the event.

30
Discharge from level III hospital
  • Letter for general pediatrician on the website

31
Oxygen reduction test
  • Criteria only O2 defined
  • Depending on saturation targets or other
    diseases
  • Practical guideline on the website

32
Logistics oxygen reduction test
  • Local?
  • Familiair with reduction test
  • Training of local pediatricians
  • Regional?
  • Research nurse?
  • Recording?
