Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy, Therapy, Safety

Primary objective: to investigate if an SpO2 threshold of 88% for children and adolescents admitted with respiratory distress results in a safe reduction of length of hospital stay, compared to an SpO2 threshold of 92%.

Secondary objectives 1

  1. To investigate if an SpO2 threshold of 88% leads to differences in duration and severity of symptoms, readmissions, time to normal activity, patient and parent quality of life and cost-effectiveness compared to an SpO2 threshold of 92%.

Conditions and MedDRA coding

Bronchiolitis

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 3

  1. Children aged 6 weeks to 12 years
  2. Hospitalized with lower respiratory distress due to bronchiolitis, viral wheeze or lower respiratory tract infection

Description
The inclusion and randomisation of a patient that fulfilled an exclusion criterion. The randomized patient was a 15-month old, born prematurely at 26 weeks gestational age , while &lt;32 is an exclusion criterion. The patient was already on supplemental oxygen (with local protocol saturation target) before randomisation. The patient was randomised to the 88% saturation target group. Supplemental oxygen without applying the new saturation target was continued due to increased work of breathing, according to the standard operation procedure of the study protocol. Further clinical deterioration later prompted the patient to be transferred to the Paediatric Intensive Care Unit. Only after this transfer did the local investigator become aware of the exclusion criterium and was the patient withdrawn from the study (study protocol dictates standard care always resumes after PICU transfer). Investigation has shown that the randomised oxygen saturation target of 88% has never been applied and therefore has not influenced the treatment of the patient at any time. The OxyKids trial was designed with a safety precaution: physicians can always commence or continue supplemental oxygen for clinical reasons other than oxygen saturation. We have seen in all cases so far that this safety precaution is applied in the correct way. The full report of this patient is attached as supporting information.

Wrongful inclusion and randomisation has previously occurred during the trial in 10 cases, out of 519 currently included. Due to the potential safety risk illustrated by the above case we felt it prudent to take further action, as well as submit this serious breach. Protocol violations of all previous 10 cases have been submitted to the sponsor. None of these patients were exposed to lower oxygen saturation or experienced adverse events. Again, this is in line with the study design where oxygen can be started for other reasons than oxygen saturation.
Sponsor actions
Even though the risk of actual undertreatment of patients not suitable for trial participation is estimated to be negligible due to the study design, we have instructed all local investigators to remind, and where necessary retrain, their staff on the exclusion criteria. To incorporate these in the informed consent procedure and double check before enrolling a patient. This e-mail with instruction has been sent on the 8th of November.
