Stelara and Tremfya Pregnancy Exposure Registry OTIS Autoimmune Diseases in Pregnancy Project

Study Purpose

The purpose of the OTIS Autoimmune Diseases in Pregnancy Study is to monitor planned and unplanned pregnancies exposed to certain medications, to evaluate the possible teratogenic effect of these medications and to follow live born infants for one year after birth. With respect to fetal outcome, it is important to evaluate the spectrum of outcomes that may be relevant to a medication exposure during pregnancy, and these include both easily recognizable defects which are visible at birth, as well as more subtle or delayed defects that may not be readily identifiable without special expertise and observation beyond the newborn period.

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
