A Phase 3 interventional study of Probiotic (Yakult) in Diarrhea, sponsored by Indian Council of Medical Research. Status unknown at 1 site in India. Open to participants aged 12 Months to 59 Months, including healthy volunteers. Per ClinicalTrials.gov, last updated 2007-09-24.
Sponsored by Indian Council of Medical Research · Phase 3, Interventional, and Prevention
A therapeutic as well as preventive role of probiotics has been suggested from results of different studies using different probiotics that have been tested, usually lactic acid producing bacteria such as lactobacillus, bifidobacterium and streptococcus species. The supplementation of probiotics to infants may also have a prophylactic effect against acute diarrhoeal diseases.
In the present proposal, we plan to examine if daily intake of a probiotic beverage, which includes 15 billion probiotic Lactobacilli, has a beneficial role in protecting children from infectious diarrhea in Kolkata.

STUDY DESIGN
It will be a double blind randomized controlled field trial involving 4000 children aged between 1 and 5 years in an urban slum of Kolkata, India. The 4000 children will be identified through demographic survey. The study will be double blinded where the study arm will receive Probiotic drink, which includes 15 billion probiotic Lactobacilli, one bottle (65ml) daily (under supervision of a Health Worker) for 12 weeks and the control arm will receive a similar drink without the lactobacilli (Nutrient drink) daily for 12 weeks. Randomization will be done in a ratio of 1:1, i.e., the study arm and control arm will include 2000 children each. All the children under the study will be visited daily by a health worker who will supervise intake of Probiotic drink or Nutrient drink by the children. All the children will be followed up daily for 24weeks for identification of acute diarrhoea cases.

METHODOLOGY
Slum areas in Kolkata Municipal Corporation with approximately 60,000 populations (approximate 15,000 families) will be selected from ward 66 to reach a sample size of minimum 4,000 children (1-5 year age).
Baseline anthropometric measurements will be taken. The diarrhoeal surveillance will be through regular household visit by CHW and stool container will be kept at each child's house to collect stool sample if diarrhoea occurs.
INCLUSION/ EXCLUSION CRITERION FOR RECRUITMENT OF PARTICIPANTS Children of either sex aged 1-5 years will be eligible for screening and parents will give and a written, informed consent form (Appendix 7) will be required from either of the parents/ guardians of each participating child. Participating children should be free from any chronic illness and also any recent illness that may compromise the immune system. In general they will have good health without known underlying illness.
Children with history of diarrhoea in the preceding 2 weeks will not be eligible.
ADMINISTRATION OF STUDY AGENTS
There will be a setup of 5 health outposts and 20 clusters (each cluster with 40 children) will be approximately of 800 children will be assigned for each health outpost. There will be 20 Community Health Workers (CHW), allocated in each health outpost will be responsible for administer of one agent code for 40 children.
SAFETY EVALUATION
Clinical monitor will evaluate adverse events due to intake of the drink.
DATA MANAGEMENT PROCEDURES
Data obtained from demographic survey (Appendix 4), daily reports and other proforma will be entered in a PC using suitable software. Data will be scrutinized for accuracy and consistency before it is entered into the PC. Data will be entered into computers in a dedicated area located at NICED, using data entry programs specially created for the project by programmer.
STATISTICAL CONSIDERATIONS
Endpoints
Efficacy will be assessed by comparing the following between the probiotic and nutrient groups:
i) Average duration of diarrhoea ii) Severity of the disease iii) Incidence of diarrhoeal disease iv) Nutritional gain v) Analysis of fecal microflora
ETHICAL ASSURANCE FOR PROTECTION OF HUMAN RIGHTS
Written informed consent will be obtained from the parent/guardian of each participating child for the Probiotic and Nutrition studies and for the safety and for permission to collect feces. The probiotic or nutritional drink is safe and has been administered to infant children, adults and the elderly.
Storage conditions
The probiotic and nutrient will be stored at 4 to 10C. Bottles taken to the field will be carried in carrying bags. Each box will have a single ice pack, and care will be taken not to freeze the contents of the bottle.
MONITORING, AUDITING, INSPECTION
Responsibilities of the investigator(s)
The principal and co-investigators at NICED will be responsible for overall supervision and management of the project. Field investigators and other co-investigators will support the PI. The PI and co-investigators will supervise all activities at health facilities and in the sites (demographic surveillance, data collection, and samples collection and transportation). They will also visit the study sites regularly.
ETHICAL AND REGULATORY STANDARDS
Ethical principle
The justification for using a nutrient in this study is that: 1) no probiotic is currently recommended for use for prevention of diarrhoeal diseases in public health programs in India and 2) a valid assessment of probiotic efficacy in Kolkata, which is endemic for diarrhoea, can only be obtained with use of a nutrient. The nutrient will consist of nutrient without lactobacillus, which will help for nutritional growth of the children.
Potential benefits
During both phases of the project, the potential benefits to participants include proper treatment and referral when needed, as well as free and accurate diagnosis of the causative agent of diarrhoeal disease. During the trial phase, the probiotic recipients are expected to benefit from the protection offered by the probiotic against diarrhoea.
Potential risks
The potential risk to the participants will be minimal, since there is extensive documentation for the safety of the probiotic to be used.
Risk/benefit ratio
The direct benefit the participants may expect from participating in this study will be free laboratory examination and treatment for diarrhoea diseases.
The main benefit of obtaining data on the efficacy of the probiotic in Kolkata will be that these data will be crucial in guiding the decision of the Indian, and perhaps other developing country governments as to whether this probiotic will be alternative approach for growth of the children as well as prevention of diarrhoeal diseases. All recipients of the probiotic will potentially benefit from the probable protective effects against diarrhoea. The risks associated with the use of the probiotic or the nutrient and various other study procedures proposed to be used in this trial are expected to be minimal to nonexistent.
Laws and regulations
The study will be performed in accordance with the principles that govern biomedical research involving human subjects, specifically the ICMR Ethical Guidelines, the Declaration of Helsinki, and the International Conference on Harmonization's Good Clinical Practice Guidelines to provide assurance that the rights, integrity, and confidentiality of trial subjects are protected and that reported results are credible and accurate.
Informed consent
Individual informed consents from parents of eligible children between 1-5 years old will be obtained. Consent will be documented by signature or thumbprint of the parents/guardian on separate sheet. The privacy and confidentiality of all data and information collected from trial participants will be ensured both during and after the conduct of the trial. Individuals will not be identified in any reports and publications based on the trial data.
Institutional review committee
Before initiation of the study, the final protocol and the informed consent will require clearance Scientific Advisory Committee of NICED, Institutional Ethics Committee of NICED, Health Ministry Screening Committee of the Government of India.
ADMINISTRATIVE ASPECTS
Record retention
The principal investigator and NICED will keep all trial documents for at least 5 years after the completion or discontinuation of the study.
