Clinical Trial Summary

The overall objective of this trial is to investigate the iron bioavailability from new infant cereals in Malawian infants.

Description:

In 30 infants aged 6 to 14 months old, the investigator will administer in random order over 2 phases separated by 14 days, 5 infant cereals containing either ferrous fumarate (4 meals) or ferrous bisglycinate (1 meal) intrinsically labeled with stable isotopes. The investigator will collect one blood sample at baseline and another sample at the end of each phase, thus 3 samples total. In these samples, fractional iron absorption and markers of iron and inflammation status will be measured . In addition, infant and child acceptability of one of the infant cereals will be assessed by using a questionnaire.

Eligibility

Inclusion Criteria:

3. Infants with allergies or intolerance to wheat, oat, gluten or other ingredients in the test cereals (e.g., celiac disease)

4. Infants participating in any other clinical trial prior to enrollment

5. Infants or infant's family who in the Investigator's judgment cannot be expected to comply with the protocol or study procedures.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Fractional iron absorption of 54FeFum (test cereal A), 57FeFum (test cereal B), 54FeFum (test cereal C).	Fractional iron absorption of 54FeFum (test cereal A), 57FeFum (test cereal B), 54FeFum (test cereal C). Based on the shift of Fe isotope ratios in the blood samples and the amount of Fe circulating in the body, the amounts of 54Fe and 57Fe isotopic label present in the blood 14 days after the test meal administrations will be calculated on the principle of isotope dilution and considering that the iron isotopic labels are not mono-isotopic	up to 6 weeks
Secondary	Fractional iron absorption of 54FeFum (test cereal C), 57FeFum (test cereal D), 58FeBisGly (test cereal E).	Fractional iron absorption of 54FeFum (test cereal C), 57FeFum (test cereal D), 58FeBisGly (test cereal E). Based on the shift of Fe isotope ratios in the blood samples and the amount of Fe circulating in the body, the amounts of 54Fe, 57Fe and 58Fe isotopic label present in the blood 14 days after the test meal administrations will be calculated as described above for the primary endpoint	up to 6 weeks
Secondary	Cereal acceptability questionnaire		up to 2 weeks
Secondary	Fractional iron absorption from infants with (CRP = 10 mg/L) or without (CRP < 10 mg/L) asymptomatic infection / inflammation.		up to 6 weeks
Secondary	Standard reporting of adverse events (AEs) for safety assessment	Reported AEs will include type, incidence, severity, seriousness and relation to intervention. All concomitant medications used to treat illnesses and other conditions will be recorded (both dose and duration).	time of consent to 24 hours after final blood draw
