Clinical Trial Summary

The purpose of this study is to compare the frequency of appearance of the total clinical manifestations (expected adverse event: nausea, vomiting, heartburn, abdominal pain, gas/swelling, diarrhea, headache, shortness of breath, metallic taste and constipation) after consuming microencapsulated iron and comparator for 14 days.


Description:

Subjects will consume a daily dose once per day for 14 days with a washout period of two menstrual cycles between the two products. After this washout period, subjects will return to the clinical and will undergo identical procedures with counter order of the intervention. Each day of the study will be recorded in a diary by each subject. Participants will be requested not to change their regular life habits and diet during the entire study.

Outcome

Type Measure Description Time frame Safety issue
Primary Frequency of appearance of the total clinical manifestations due to the consumption of both products The proportion of participants that reported at least one adverse event, which refers to the total of clinical manifestations due to the consumption of both products. Symptoms that were considered: nausea, heartburn, abdominal pain, gas/swelling, diarrhea, vomits, metallic taste, constipation, headache and respiratory distress. This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Frequency of appearance of each of the total clinical manifestations due to the consumption of both products The proportion of participants that reported at least one adverse event, which refers to each of the total of clinical manifestations due to the consumption of both products (individual symptoms that were considered: nausea, heartburn, abdominal pain, gas/swelling, diarrhea, vomits, metallic taste, constipation, headache and respiratory distress) This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Change in the total number of incidences/complaints related to the study product Symptoms: nausea, heartburn, abdominal pain, gas/swelling, diarrhea, vomits, metallic taste, constipation, headache, and respiratory distress This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Number of clinical manifestations that subjects experience Symptoms: nausea, heartburn, abdominal pain, gas/swelling, diarrhea, vomits, metallic taste, constipation, headache, and respiratory distress This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Overall intensity of clinical manifestations that subjects experience (nausea, heartburn, abdominal pain, gas/swelling) Intensity was measured with VAS scale This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Overall intensity of clinical manifestations that subjects experience (diarrhea and vomits) Intensity was measured with number of times. This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Change in the acute intensity of adverse effects that subjects experience Symptoms: Nausea, heartburn, abdominal pain, gas/swelling, vomits, diarrhea, constipation, metallic taste, headache, and respiratory distress This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Duration (number of days) of clinical manifestation This variable was measured in total duration (number of days) of symptom onset (symptoms: nausea, heartburn, abdominal pain, metallic taste, headache, diarrhea, constipation, gas/swelling, respiratory distress and vomits) This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Duration (minutes per day) of clinical manifestation Daily duration (minutes) of symptom (nausea, heartburn, abdominal pain, gas, metallic taste, headache, and respiratory distress) This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Health status using VAS scale Health status (daily and with respect to the previous day) This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Physical activity Proportion of participants that experienced any impact on daily activity This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Bowel movements Number of times subjects go to the toilet. This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Stool morphology Stool type (Bristol scale) This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Sleep quality Sleep quality measured on a scale of 1 to 5 (1 being poor sleep quality and 5 being very good sleep quality). This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Sleep duration Number of hours subjects sleep This variable will measure the changes in clinical manifestations during the period of each of the intakes, i.e., for 14 days, and during the washout period.
Secondary Ferritin Iron profile. By means of a blood draw. Day 1 and day 14 of each product consumption.
Secondary Saturated transferrin Iron profile. By means of a blood draw. Day 1 and day 14 of each product consumption.
Secondary Serum iron Iron profile. By means of a blood draw. Day 1 and day 14 of each product consumption.
Secondary Hemoglobin Iron profile. By means of a blood draw. Day 1 and day 14 of each product consumption.
Secondary Safety variables Safety parameters (physical examination, vital signs, blood and urine laboratory tests, adverse events other than expected in the study) Day 1 and day 14 of each product consumption.
