Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 second to 8 months (Child)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Infants <8 months of age.

  2. Infants with a clinical diagnosis of Cow's Milk Allergy (CMA) per local hospital practice, including any of the following criteria:

    1. Based on clinical examination with a careful history, parent-reported symptoms suggestive of CMA, and disappearance of the symptoms when cow's milk was eliminated from the diet for at least two weeks prior to study entry
    2. Based on clinical examination with a careful history, parent-reported symptoms suggestive of CMA, and disappearance of the symptoms while being breastfed with maternal cow's milk protein elimination diet for at least two weeks prior to study entry
    3. History of CoMiSS® score >10 indicating symptoms are likely cow's milk allergic prior to study entry
    4. History of positive result of an oral food challenge with cow's milk prior to study entry
    5. Presence of specific Immunoglobulin E (IgE) to cow's milk protein based on skin prick test (wheel size ≥3mm) or radio-allergosorbent-test (RAST) (>0.7 kilounit per liter (kU/L)) prior to or on the day of study entry.
  3. 3. Infants that are still on dairy-derived extensively hydrolysed formula, amino acid-based formula, hydrolysed rice protein formula, soy-based formula or being breastfed by mothers who are on cow's milk protein elimination diet at study entry.
  4. Parents / guardians confirm their intention not to administer any products containing cow's milk protein during the study.
  5. Expected to consume the specified age-dependent minimum amount of study product per day during the study.
  6. Expected to require a milk substitute for CMA management for at least 16 weeks.
  7. Written informed consent provided by parents / guardians, according to local law.

Exclusion Criteria:

  1. Birth weight-for-age z-score <-2 Standard Deviation (SD) or >+2SD.
  2. Infants <37 weeks gestation requiring specific premature formula at the time of study entry.
  3. Infants with severe concurrent illness and/or have undergone gastrointestinal surgery such as bowel resection or stoma placement and/or with Down syndrome or other syndromes where functional gastrointestinal disorders are common.
  4. Infants that are more suitable to use Amino Acid Formula (AAF) as first-line formula, including but not limited to those with high risk of anaphylaxis (prior history of anaphylaxis and currently not using extensively Hydrolysed Formula (eHF)), faltering growth / failure to thrive, or severe forms of non-IgE-mediated CMA such as eosinophilic oesophagitis, enteropathies, or Food Protein-Induced Enterocolitis Syndrome (FPIES).
  5. Infants with diagnosis of rice allergy or known allergy to any of the ingredients in the study product.
  6. Investigator's uncertainty about the willingness or ability of the parents / guardians to comply with the protocol requirements.
  7. Participation in any other studies involving investigational or marketed products concomitantly or within two weeks prior to entry into the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
