About this study

Official title: Improving the Immune Response to Rotavirus Vaccine

Rotavirus is the leading cause of severe gastroenteritis in infants and young children worldwide and is estimated to account for 600,000 deaths in children <5 years of age. However, live oral enteric vaccines (e.g. OPV, cholera vaccines, typhoid vaccine) have been less immunogenic in poor communities with high levels of malnutrition and poor sanitation. Rotavirus vaccines also appear to be less immunogenic in the setting where they are most needed. High maternal antibody (IgG) to rotavirus and breast feeding near the time of vaccination may inhibit rotavirus vaccine effectiveness. We propose a quick study to look at practical ways to improve the immunogenicity of rotavirus vaccine in our own setting in Bangladesh. The objectives are to assess if delaying Rotarix vaccination will improve the immune response to the vaccine and to assess if avoiding breastfeeding in the 45 minutes before and after vaccine administration will improve the immune response to administration of Rotarix vaccine. The study will be conducted in the urban Dhaka Mirpur Community, a setting where previous rotavirus vaccine immunogenicity studies have been successfully conducted. A total of 300 infant will be randomly assigned to one of the following groups: 1) Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus vaccine with no intervention in normal breastfeeding practices before and after receiving vaccine. 2) Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration. 3) Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus, with no intervention in normal breastfeeding practices before and after receiving vaccine. 4) Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration. Blood and stool samples will be collected from infants and breast milk from mothers. The primary outcome is to determine the sero-conversion rate of anti-rotavirus IgA in different groups of infants.

Read the detailed description

The study will be conducted in a suburb of Dhaka in the area of Mirpur. Mirpur is one of the 14 Thanas of Dhaka cities with a population of about one million in an area of 59 square kilometers. Mirpur Thana of Dhaka city is divided into several sections. There are 14 sections in Mirpur Thana. The area is densely populated and located 20 minutes away from the lCDDR,B's Dhaka Hospital . The population is stable with low socioeconomic conditions. The average income in the slum areas of Mirpur is Tk.4200 (about US $ 62) per month per family. 25% of fathers and 15% of mothers have more than 5 years of formal education. The study will be conducted in section 11 and 12 of Mirpur which has a population of about 500,000. We recently conducted phase I and II of the rotavirus vaccine study in this site. Several other studies (phase II ETEC, killed cholera vaccine) are ongoing in this area. Children will be identified through active surveillance of new births in the community and the study subjects will be recruited through home visits by the locally recruited field workers.

2.2 .Design : Randomized intervention trial

Study groups:

  1. Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus vaccine with no intervention in normal breastfeeding practices before and after receiving vaccine.
  2. Administration of Rotarix at 6 and 10 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration.
  3. Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus, with no intervention in normal breastfeeding practices before and after receiving vaccine.
  4. Administration of Rotarix at 14 and 18 weeks co-administered with oral polio virus. Breastfeeding will not be permitted 45 minutes prior to vaccine administration and 45 minutes after each vaccine administration.

Samples collected:

  • Blood draw at the time of first dose of Rotavirus vaccine and 4 weeks after the second dose
  • Breast milk sample at 6 weeks for the mothers in study groups A and B, and at 14 weeks for mothers in study groups C and D (see below for groups).
  • Stool sample prior to dose one and on day 3 and 7 after each dose to look for vaccine virus shedding

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Rotavirus Vaccine & Breastfeeding in people with Healthy Infants and Mothers, run by International Centre for Diarrhoeal Disease Research, Bangladesh at 1 site in Bangladesh.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Bangladesh. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Immunogenicity of Rotavirus Vaccine (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Apr 2013.
