Lactating Women on Select DOI, Breastfed Infants of Mothers on Select DOI

Brief summary

Over half of women in the US who are breastfeeding their infants take prescription drugs. You are being asked to participate in this study because you are breastfeeding your infant and are currently taking, as part of your medical care, at least one of the drugs we are studying. We are interested in studying drugs commonly prescribed to women who are breastfeeding so we can learn more about the amount of drug that is transferred to breastmilk and estimate how much of drug that is consumed by breastfed infants.

Detailed description

The purpose of this study is to understand if the study drugs of interest are found in breastmilk and how much; to estimate the amount of drug that is consumed by breastfed infants and what effect this may have on infants; and to share what we learn with other researchers. The study drugs of interest have Food and Drug Administration (FDA) approval, but there is little or no information about the amount of drug found in the breastmilk of mothers who take them; the amount of drug that may be transferred to their infant's through breastmilk; or the effects this transfer may have on their infants. During this study we will ask to collect breastmilk and blood from mothers, and blood from infants, to measure the amount of study drug of interest in these body fluids. Results from this study will help researchers better understand how much of the study drug of interest is in your blood and breastmilk, and how much of the study drug of interest may be in your infant's blood because of breastfeeding.

Lactating women who are not legal adults and their breastfed infants may be enrolled if they assent to participate in the study and consent is obtained from their legal guardian according to local IRB/REB/IEC guidelines.

Design outcomes

Primary

MeasureTime frameDescription
M/P ratioUntil the infant becomes 180 days of ageCharacterize the pharmacokinetics using maternal milk/plasma exposure ratio is calculated by dividing the BMS01 drug of interest breastmilk concentration by the BMS01 drug of interest in maternal plasma concentration.
DIDUntil the infant becomes 180 days of agePharmacokinetics is characterized by estimated daily infant dose-daily infant dose which estimates the quantity of drug delivered to an infant via breastmilk in a given day.
RIDUntil the infant becomes 180 days of agePharmacokinetics is characterized by relative infant dose is a method of relating the potential dose of the drug delivered to the infant to the typical therapeutic dose given to the mother.
I/M ratioUntil the infant becomes 180 days of agePharmacokinetics is characterized using infant maternal/exposure ratio. IM ratio is calculated using the average infant plasma concentration of the BMS01 drug of interest and historical value of clearance in infants.

Secondary

MeasureTime frameDescription
Safety profile of commonly used drugs in infants exposed to drugs in breastmilkUntil the infant becomes 180 days of agesee Cohort 1-31 for listing of drugs
AEUp until 180 days of ageSafety profile of commonly used drugs in infants exposed to drugs in breastmilk is characterized by Adverse Events(AE) which are collected at each time point when the study-specific procedure occurred and up until 1 hour after.
SAEUp until 180 days of ageSafety profile of commonly used drugs in infants exposed to drugs in breastmilk is characterized by Serious Adverse Events which are directly related to study procedures and were recorded from participants (infant or mother) at each time point when the study-specific procedure occurred and up until 1 hour after.
ESIUntil the infant becomes 180 days of ageSafety profile of commonly used drugs in infants exposed to drugs in breastmilk is characterized by Events of Special Interest(ESI) which include any pre-specified safety event that could be related to BMS01 drug of interest exposure. ESI's are only assessed for infants and only at study visits from the time the BMS01 DOI was initiated in mother and infant began breast milk feeding through the end of the study / infant age ≤ 180 days
