Study of a Novel Tetravalent Dengue Vaccine in Healthy Children Aged 2 to 14 Years in Asia
Efficacy and Safety of a Novel Tetravalent Dengue Vaccine in Healthy Children Aged 2 to 14 Years in Asia
The aim of the trial was to assess the efficacy of the CYD dengue vaccine in preventing symptomatic, virologically-confirmed dengue (VCD) cases.
Primary Objective:
To assess the efficacy of CYD dengue vaccine after 3 vaccinations at 0, 6, and 12 months in preventing symptomatic VCD cases, regardless of the severity, due to any of the four serotypes in children aged 2 to 14 years at the time of inclusion.
Secondary Objectives:
- To describe the efficacy of CYD dengue vaccine in preventing symptomatic VCD cases after the third dose to the end of the Active Phase, after at least 1 dose, and after 2 doses.
- To describe the occurrence of serious adverse events (SAEs), including SAEs of special interest in all participants throughout the trial period.
- To describe the occurrence of hospitalized virologically-confirmed dengue (VCD) cases and the occurrence of severe (clinically-severe or as per World Health Organization (WHO) criteria) VCD cases, throughout the Surveillance Expansion period (SEP) and throughout the trial (from Day 0 to the end of the study).
- To describe the antibody response to each dengue serotype after Dose 2, after Dose 3, and 1 and 5 years after Dose 3.
Study Overview
Status
Conditions
Detailed Description
Participants were randomized to either receive 3 injections of CYD dengue vaccine or a placebo at 0, 6, and 12 months.
A subset of participants from each country were also evaluated for reactogenicity and immunogenicity.
Participants who consented to participate in the SEP were actively followed for dengue case detection (i.e. at least weekly contact and capturing any acute febrile illness, not just hospitalized febrile cases, as in the Active Phase). The SEP was designed to maximize the detection of symptomatic confirmed dengue (hospitalized or not) in order to describe CYD dengue vaccine efficacy and safety in preventing symptomatic dengue. Participants who declined participating in the SEP continued surveillance as in the Hospital Phase until trial completion.
Symptomatic VCD cases occurring more than (>) 28 days after dose 3 (during the Active Phase) are defined as:
- Acute febrile illness (i.e. temperature >=38 C on at least 2 consecutive days)
Virologically confirmed by dengue Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) and/or dengue non-structural (NS)1 enzyme-linked immunosorbent assay (ELISA) Ag test
1997 WHO Classification Dengue hemorrhagic fever (DHF) cases were defined as per the 1997 WHO criteria of clinical manifestations; a) Fever: acute onset, high (>= 38°C) and continuous, lasting 2 to 7 days and (b) any of the pre-listed hemorrhagic manifestations and laboratory findings of thrombocytopenia (platelet<=100 x 109/L) and plasma leakage as shown by hemoconcentation (hematocrit increased by 20 percent [%] or more) or pleural effusion (seen on chest X-ray [CXR]) and/or ascites and/or hypoaluminemia. The first two clinical criteria plus thrombocytopenia and signs of plasma leakage are enough to establish a clinical diagnosis of DHF.
DHF was graded as follows:- Grade I: Fever accompanied by non-specific constitutional symptoms; the only hemorrhagic manifestation is a positive tourniquet test; Grade II: Spontaneous bleeding in addition to the manifestations of Grade I participants, usually in the form of skin and/or other hemorrhages; Grade III: Circulatory failure manifested by rapid and weak pulse, narrowing of pulse pressure (20 mmHg or less) or hypotension, with the presence of cold clammy skin and restlessness; and Grade IV: Profound shock with undetectable blood pressure and pulse.
Independent Data Monitoring Committee (IDMC) severity criteria The severity of VCD cases was assessed by an Independent IDMC using pre-defined standardized criteria. Following manifestations of severity were considered in all suspected VCD cases; 1) Platelet count <= 100000μl and bleeding (tourniquet, petechiae or any bleeding) plus plasma leakage (effusion on CXR OR clinically apparent ascites or hematocrit >=20% above baseline recovery level) 2) Shock (pulse pressure <= 20 mmHg in a child, or hypotension [<= 90 mmHg] with tachycardia, weak pulse and poor perfusion) 3) Bleeding requiring blood transfusion 4) Encephalopathy i.e. Unconsciousness or poor conscious state or convulsionsfitting not attributable to simple febrile convulsion as defined in the guidelines for definition and collection of febrile convulsions or focal neurological signs. Poor conscious state or unconsciousness must be supported by Glasgow Coma Scale (GCS) score. 5) Liver impairment (aspartate aminotransferase [AST] >1000IU/L or prothrombin time [PT] International normalized ratio [INR] >1.5) excluding other causes of viral hepatitis 6) Impaired kidney function (serum creatinine ≥ 1.5 mg/dL) 7) Myocarditis, pericarditis or clinical heart failure supported by CXR, echocardiography, electrocardiogram (ECG) or cardiac enzymes.
The designation of such cases as severe or otherwise will be made on a case by case basis by the IDMC.
