The Registry conforms to the FDA Guidance for Industry: Establishing Pregnancy Exposure
Registries, the Guidelines for Good Pharmacoepidemiology Practices, and the FDA Guidance on
Pharmacovigilance.
The Antiretroviral Pregnancy Registry collects data on use of the following GSK drugs:
abacavir, amprenavir, delavirdine, fosamprenavir, lamivudine, maraviroc, zidovudine, and
their combinations during pregnancy. The Registry requests information from medical providers
about antiretroviral therapy, though there may be other drug exposures, which are not
systematically collected.
Registration is voluntary. Health professionals are strongly encouraged to enroll their
antiretroviral-exposed pregnant patients into the Registry as early in the pregnancy as
possible, preferably before prenatal testing is done. This is to maximize the data validity
by minimizing potential biases introduced when a woman is enrolled after prenatal testing.
Patients are followed through health care providers who provide information on maternal risk
factors, pregnancy outcome, and neonatal health. In the month of expected delivery, a short
follow-up form is sent to the health care provider to ascertain the pregnancy outcome and
completion of the antiviral therapy information. Additional follow-up is not sought from
health care providers.
In an attempt to limit the bias in the analysis, the Registry assembled a group of providers
who committed in writing to report every woman who receives antiretroviral therapy during
pregnancy, but before the pregnancy outcome is known, that comes to their site. This allows
the Registry to include every report from that site as an evaluable case. As the number of
cases from these sites increases, the Registry will be able to analyze those cases
separately. Providers are encouraged to participate in this group.
