Main objective

Scope: Efficacy

To compare the incidence rate of overall respiratory morbidity in otherwise healthy (neonate who does not display any major short-or-long-term morbidity related to prematurity) preterm babies 29 +0 -35+6 wGA exposed to prophylaxis with palivizumab (Group A) vs infants 29+0 - 35+6 wGA NOT exposed to prophylaxis with palivizumab (Group B)

Secondary objectives 2

  1. To evaluate the difference of RSV-related hospitalization due to low respiratory infection during the first RSV-season (November 1st-March 31th) between Group A and Group B.
  2. To evaluate direct and indirect costs related to respiratory sequelae in both groups. The following information for an accurate cost evaluation will be collected: lenght of hospitalizations; need for Mechanical Ventilation and other support therapies; Intensive Care Unit admission and length of stay; medical specialistic visits; drugs (type, dosage and therapy duration); diagnostic exams, loss of working days for parents due to child illness.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Overall respiratory morbidity (composite primary endpoint), whose definition is: a) LRTIs by any pathogen (including, but not limited to RSV); b) recurrent wheezing (quantified as presence of wheezing days and/or need for use of antiwheezing drugs ) +/- asthma

Secondary endpoints 3

  1. Difference of number of RSV-related hospitalizations due to low respiratory tract infection during the first RSV-season (November 1st- March 31th) between Group A and Group B.
  2. Direct costs in terms of difference of health resources used by Group A and Group B respectively and related to: lenght of hospitalizations(days);mechanical ventilation and other support therapies(type, number, duration);Intensive Care Unit admission and lenght of stay(days);outpatient visits(type and number of specialistic visits);drugs(type, dosage and therapy duration);diagnostic tests(type and number).Costs for resources used will be calculated using National Health Service tariffs
  3. Indirect costs in terms of loss of working days for due to child illness

Description
During the pandemic period, the investigator found it necessary to make some deviations from the original study protocol in order to address the unprecedented challenges that the health and epidemiological situation was presenting. In particular, it became evident that the COVID-19 pandemic could put the health of many patients, especially children, at risk of viral respiratory infections, such as respiratory syncytial virus (RSV). To ensure adequate protection for all patients involved in the study and to limit the risk of RSV infection, the investigator decided to force randomisation by administering the Investigational Medicinal Product (IMP) to almost all participants. This decision was taken with the intention of ensuring effective and timely prophylaxis, thus helping to avert a possible collapse of health facilities already overburdened by the pandemic. Moreover, during this period, many patients did not have the opportunity to receive adequate care from their paediatricians, due to the limited accessibility of primary health services and the high demand for medical care related to the pandemic. Consequently, hospitalisation was necessary to ensure adequate monitoring and treatment. The approach adopted by the investigator, although not in accordance with the study protocol, was dictated by reasons of public safety and the need to protect the health of patients in an extremely critical, unpredictable, unexpected context that could not be dealt with by ordinary means. It is important to note that no SAEs were recorded in the last reporting period; in fact, all the SAEs listed in Table 2 occurred before 2022 and were already reported in previous DSURs.
Sponsor actions
This deviation did not have any negative impact on patient safety; on the contrary, it significantly helped mitigate health risks for the participants during a critical epidemiological situation.
The impact on the integrity of the study data, resulting from the suspension of randomization, was addressed through the revision of the Statistical Analysis Plan (SAP), which includes specific sensitivity analyses to assess the effect of the deviation.
The study site had to implement a protocol deviation/correction during the period from November 2020 to March 2022 due to the COVID-19 pandemic. Specifically, to protect the vulnerable population involved (preterm infants), randomization was temporarily suspended.
The Principal Investigator (PI) and the sponsor deemed it clinically and ethically unacceptable to assign subjects to the placebo arm (as per the protocol, which provides for a 1:1 randomization between palivizumab and placebo), in order to reduce the risk of respiratory syncytial virus (RSV) infection and the resulting need for hospitalization in pediatric wards, including intensive care units.
Measures implemented by the CRA:
• The deviation was documented in the study management system and comprehensively detailed in the monitoring reports.
• The CRA discussed the deviation with the Principal Investigator (PI) and the study sponsor.
• The site staff was trained and reminded to promptly document and report any extraordinary clinical decisions that could lead to protocol deviations.
Measures implemented by the PI/Sponsor:
• The sponsor did not repeat the deviation and incorporated the occurrence into the revision of the statistical analysis plan.
