About this study

Official title: A Parallel-Group, Randomized, Open-Label, Controlled Study to Evaluate the Efficacy and Safety of a Zinc-Containing Dietary Supplement (Biolizin) in Improving Functional Poor Appetite in Children Aged 6 to 36 Months

Functional poor appetite is common in young children and may be linked to suboptimal micronutrient intake and feeding behavior. This study evaluates whether a zinc-containing oral supplement (Biolizin syrup) can improve eating behavior in children aged 6 to 36 months who have poor appetite without an identifiable medical cause. Participants are followed for 42 days with clinic visits at Day 0, Day 7, Day 21, and Day 42. Caregivers complete validated questionnaires about feeding difficulties and eating behavior; the child's weight and length/height are measured at each visit. Safety is assessed through review of adverse events and routine laboratory tests; serum zinc may be measured according to the protocol. The primary outcome is the change from baseline to Day 42 in the total score of a validated feeding-difficulty scale. Secondary outcomes include changes in Children's Eating Behaviour Questionnaire (CEBQ) subscales, WHO growth indices, serum zinc (if measured), and overall safety

Read the detailed description

Poor appetite in toddlers often reflects a combination of nutritional and behavioral factors. Zinc is an essential trace element that contributes to taste perception, mucosal integrity, and appetite regulation; suboptimal zinc status may exacerbate reduced intake and feeding problems. Biolizin is an oral zinc-containing supplement intended to support appetite and healthy feeding behavior in young children. The study aims to determine whether the supplement, provided together with standardized caregiver counseling on responsive feeding practices, improves caregiver-reported feeding difficulty and eating behavior over 42 days. After consent and screening, eligible children attend visits at Day 0, Day 7 (±2), Day 21 (±3), and Day 42 (±4). At each visit, clinicians review medical history and concomitant treatments, record anthropometrics, and caregivers complete a validated Vietnamese feeding-difficulty scale (0-24, higher scores indicate worse difficulty) and the CEBQ subscales. The study product is taken orally per age-based dosing specified in the protocol; adherence is checked using dosing diaries and returned bottle counts where applicable. Safety laboratories (e.g., complete blood count, liver and renal chemistry) are planned at baseline and Day 42; serum zinc may be obtained according to protocol. Adverse events are collected from consent through Day 42 and are managed according to clinical judgment; expected reactions are generally mild (for example, gastrointestinal discomfort, taste changes, or rash). Source data are recorded in case report forms and entered into a secure database with audit trails, and only de-identified data are used for analysis or sharing. The study has ethics approval and written informed consent is obtained from caregivers before any procedures.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • BiolizinDietary supplement

    Oral zinc-containing syrup taken per age-based dosing specified in the protocol, once or twice daily for 42 consecutive days. Product is dispensed at baseline (with refill if needed); batch and expiry are recorded. Caregivers receive instructions for use and complete dosing diaries; adherence is checked by diary review and returned bottle counts. Concomitant zinc products or pharmacologic appetite stimulants are not allowed. Safety is monitored through adverse event review and routine laboratory tests at baseline and Day 42.

  • Standardized caregiver counseling on responsive feedingBehavioural

    Structured counseling delivered to caregivers at each clinic visit (Day 0, Day 7, Day 21, Day 42). Content includes mealtime routines, recognizing hunger/satiety cues, age-appropriate portions and textures, repeated exposure to diverse foods, and strategies to manage refusal or prolonged meals. A brief checklist guides delivery to ensure consistency across visits. No dietary supplement is provided in this intervention.

Biolizin Syrup + Standardized Caregiver CounselingExperimentalChildren receive an oral zinc-containing dietary supplement (Biolizin syrup) for 42 days, dosed by age per protocol, together with standardized caregiver counseling on responsive feeding at each study visit (Day 0, Day 7, Day 21, Day 42). Adherence is monitored with dosing diaries and returned bottle counts. Use of other zinc-containing products or appetite stimulants is not permitted. Outcomes (feeding-difficulty score, CEBQ subscales, anthropometrics, and safety labs) are collected per schedule
Receives: Dietary Supplement: Biolizin; Behavioral: Standardized caregiver counseling on responsive feeding
Counseling Only (Standardized Feeding-Behavior Counseling)Active comparatorChildren receive the same standardized caregiver counseling on responsive feeding at each study visit (Day 0, Day 7, Day 21, Day 42) without Biolizin or any other zinc-containing supplement. Education materials, visit frequency, and assessments match the experimental arm. Concomitant appetite stimulants or zinc products are not allowed. Outcomes are collected per the same schedule.
Receives: Behavioral: Standardized caregiver counseling on responsive feeding

What is being measured

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

  1. Change in Children's Eating Behaviour Questionnaire (CEBQ) Composite Total Score from Baseline to Day 42

    The CEBQ is a validated parent-reported questionnaire assessing eating behaviors in children. Each item is scored from 1 (never) to 5 (always). The composite total score is derived from multiple domains (range: 1-5). Higher scores indicate more adverse eating behaviors (worse outcome). A negative change (Day 42 - Baseline < 0) indicates improvement.

    Measured: Baseline to Day 42

  2. Change in Children's Eating Behaviour Questionnaire (CEBQ) Food Approach Behaviors from Baseline to Day 42

    The Children's Eating Behaviour Questionnaire (CEBQ) is a validated parent-reported questionnaire assessing eating behaviors in children. The "food approach" score is the mean of four subscales: Enjoyment of Food, Food Responsiveness, Emotional Overeating, and Desire to Drink. Each item is scored from 1 (never) to 5 (always). Subscale scores range from 1-5, with higher values indicating greater food approach behaviors (worse outcome). A negative change indicates improvement.

    Measured: Baseline to Day 42

  3. Change in Children's Eating Behaviour Questionnaire (CEBQ) Food Avoidant Behaviors from Baseline to Day 42

    Mean change in Children's Eating Behaviour Questionnaire (CEBQ) "food avoidant" subscales (Satiety Responsiveness, Slowness in Eating, Food Fussiness, Emotional Undereating). Lower scores indicate less avoidance; negative change denotes improvement.

    Measured: Baseline to Day 42

  4. Responder Rate on Children's Eating Behaviour Questionnaire (CEBQ) (≥30% Improvement) at Day 42

    Proportion of participants achieving ≥30% decrease from baseline in the pre-specified Children's Eating Behaviour Questionnaire (CEBQ) adverse-behavior composite (per SAP).

    Measured: Day 42

Secondary outcomes (8)
  1. Change in Hoang Thi Bach Yen Anorexia Scale (Vietnamese Caregiver-Reported Pediatric Anorexia Scale) Total Score from Baseline to Day 42

    The Hoang Thi Bach Yen Anorexia Scale (2020) is a validated Vietnamese caregiver-reported instrument to assess poor appetite in children. It includes 8 items covering mealtime characteristics (duration, amount of food intake) and eating behaviors (oppositional behavior, avoidance, food selectivity, food refusal). Each item is scored from 0 to 3 (0 = no symptom, 3 = severe symptom). The total score ranges from 0 to 24. Higher scores indicate worse appetite (more severe anorexia). Lower scores indicate better appetite. A negative change (Day 42 - Baseline < 0) reflects clinical improvement.

    Measured: Baseline to Day 42

  2. Change in Body Weight from Baseline to Day 42

    Body weight will be measured in kilograms (kg) at baseline and Day 42. The outcome is the mean change (Day 42 - Baseline). Weight-for-age Z-scores based on WHO growth standards may also be summarized descriptively.

    Measured: Baseline to Day 42

  3. Change in Number of Daily Meals from Baseline to Day 42

    Caregiver-reported average number of meals per day over the prior week; outcome is change (Day 42 - Baseline).

    Measured: Baseline to Day 42

  4. Change in Mean Meal Duration from Baseline to Day 42

    Caregiver-reported average minutes per meal over the prior week; outcome is change (Day 42 - Baseline).

    Measured: Baseline to Day 42

  5. Change in Caregiver-Rated Cooperation During Meals Scale Score from Baseline to Day 42

    Caregiver-Rated Cooperation During Meals Scale is a study-specific, caregiver-reported measure of mealtime cooperation. The instrument uses a 5-point Likert scale ranging from 1 (very uncooperative) to 5 (very cooperative). Higher scores indicate better cooperation (favorable outcome). A positive change (Day 42 - Baseline > 0) reflects improvement.

    Measured: Baseline to Day 42

  6. Incidence and Severity of Treatment-Emergent Adverse Events (TEAEs)

    Number and proportion of participants with ≥1 TEAE; events characterized by system organ class/preferred term and graded by CTCAE v5.0. Collected using the study's standard ADR form.

    Measured: From first dose to Day 42

  7. Change in Serum Zinc Concentration from Baseline to Day 42

    Serum zinc (µg/dL) measured per site laboratory procedures; outcome is change (Day 42 - Baseline).

    Measured: Baseline to Day 42

  8. Change in Body Length/Height from Baseline to Day 42

    Body length (for children <24 months) or standing height (for children ≥24 months) will be measured in centimeters (cm) at baseline and Day 42. The outcome is the mean change (Day 42 - Baseline). Length/height-for-age Z-scores based on WHO growth standards may also be summarized descriptively.

    Measured: Baseline to Day 42
