Trial summary

The goal of this clinical trial is to evaluate efficacy and safety of Zinc-L carnosine/Polaprezinc in infants with GER. Researchers will compare Zinc-L carnosine/Polaprezinc to a placebo (a look-alike substance that contains no drug) to see if Zinc-L carnosine/Polaprezinc works to treat infants with GER.

About this study

Official title: Efficacy and Safety of Polaprezinc/Zinc L-carnosine (Hepilor) in Infants With Gastroesophageal Reflux

The goal of this clinical trial is to evaluate efficacy and safety of Zinc-L carnosine/Polaprezinc in infants with GER.

Researchers will compare Zinc-L carnosine/Polaprezinc to a placebo (a look-alike substance that contains no drug) to see if Zinc-L carnosine/Polaprezinc works to treat infants with GER.

Participants will:

Take drug Zinc-L carnosine/Polaprezinc or a thickened formula every day for 8 weeks Visit the clinic once every 4 weeks for checkups and questionnaires

Read the detailed description

This will be a randomised, single blind, controlled, study, designed to evaluate efficacy and safety of Zinc-L carnosine/Polaprezinc in infants (1-12 months of age) with symptoms suggestive of GER. The study will include a 2-week screening period, and a 8-week parallel arms treatment period. After the screening phase, eligible patients will be randomly assigned to either thickened formula or polaprezing twice a day, in a 1:1 ratio, for 8 weeks. Study visits will be conducted every 4 weeks during the treatment period. All the subjects will be blindly allocated by means of scratch cards to one of the two treatment groups according to a computer-generated randomisation list provided by our statistician. A validated program will be used by an independent statistician to generate a randomisation list with blocks, block size=4, pre-allocated to centres. Only study investigators will be blinderd to the randomisation codes. The codes will be kept confidential until the end of the study when the randomisation code will be broken after the database lock. All subjects will undergo a formal clinical assessment. The protocol will be approved by and indipendent etichs committee and conducted according to the Declaration of Helsinki and the principles of good clinical practice.

Eligible patients with symptoms meeting Rome IV criteria for diagnosis of Infant Regurgitation will be recruited from Sant'Andrea University Hospital and from Children Hospital SS Antonio E Biagio E C. Arrigo.

The estimated total sample size that was aimed was 48 (24 children per arm) with the power of 80% (alpha of 5%). We estimated a dropout rate of 20% and aimed to recruit 60 participants to provide at least 48 evaluable assessments.

Efficacy analysis will be performed on ITT population. A sensitivity analysis on PP population will be carried out only if 5% or more ITT subjects are excluded from PP population.

Comparison between the two groups will be performed according to ANCOVA model. For all ANCOVA models, the assumptions of normality and homogeneity of variance will be investigated. Violation of these assumptions will be overcome by performing a non-parametric test (the Wilcoxon Rank Sum test).

Statistical analysis will be performed using the computer software SPSS 25.0

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. I-GERQ-R questionnaire

    The primary outcome will be the quantitative improvement in Infant Gastroesophageal Reflux Questionnaire Revised (I-GERQ-R) score from baseline to the end of the treatment period. The total score ranges from 0 to 42. A cut-off of ≥ 16 has been suggested to discriminate between GER and GER-disease.

    Measured: From enrollment to the end of treatment at 8 weeks.

Secondary outcomes (1)
  1. Acceptability

    Secondary outcome will be the evaluation of product acceptability according to a five-point Likert scale, ranges from 1 (very poor) to 5 (very good)

    Measured: From enrollement to the end of treatment at 8 weeks.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06678997, which also lists 1 linked publication.

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?
