Prospective Registry of Exposure to Gepotidacin (PREG)

September 29, 2026 updated by: GlaxoSmithKline

Prospective Registry of Exposure to Gepotidacin (PREG): a Prospective Registry of Women and Their Offspring Exposed to Gepotidacin During Pregnancy

The purpose of this study is to monitor pregnancies exposed to gepotidacin and to evaluate possible teratogenic effects or birthweight-lowering effects of this medication relative to the primary outcomes of major congenital malformations (MCMs) and small for gestational age (SGA), as well as to evaluate secondary maternal, fetal, and infant outcomes.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of infants with major congenital malformations (MCMs)
Time Frame: At pregnancy outcome, with follow-up through 12 months after delivery

An abnormality of body structure or function that is present at birth, is of prenatal origin (i.e., birth defect), has significant medical, social, or cosmetic consequences for the affected individual, and typically requires medical intervention.

At pregnancy outcome, with follow-up through 12 months after delivery
Number of infants with small-for-gestational-age births (SGA)
Time Frame: At live birth

A newborn infant whose birth weight is less than (<) 10th percentile for sex and gestational age using standard growth charts for full- and preterm live-born infants.

At live birth

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of infants with minor congenital malformations
Time Frame: At live Birth, with follow-up up through 12 months of age

An anomaly or abnormality of body structure that is present at birth, is of prenatal origin (i.e., birth defect), poses no significant health problem in the neonatal period, and tends to have limited social or cosmetic consequences for the affected individual.

At live Birth, with follow-up up through 12 months of age
Number of participants (pregnant women) with pregnancy termination
Time Frame: From date of conception (DOC) to <20 gestational weeks

A voluntary fetal loss or interruption of pregnancy that occurs for any reason, including but not limited to for the preservation of maternal health or because of fetal abnormalities.

From date of conception (DOC) to <20 gestational weeks
Number of participants (pregnant women) with spontaneous abortions (SAB)
Time Frame: From date of conception (DOC) to <20 gestational weeks

An involuntary fetal loss or the expulsion of the products of conception occurring at less than (<) 20 gestational weeks.

From date of conception (DOC) to <20 gestational weeks
Number of participants (pregnant women) with stillbirths
Time Frame: From 20 weeks' gestation to pregnancy outcome

Stillbirth is defined by the American College of Obstetricians and Gynecologists (ACOG), an involuntary fetal loss occurring at greater than or equal to (>=) 20 weeks of gestation, or, if gestational age is unknown, a fetus weighing >=350 grams.

From 20 weeks' gestation to pregnancy outcome
Number of participants (pregnant women) with preeclampsia
Time Frame: From 20 weeks' gestation to pregnancy outcome

Preeclampsia is disorder of pregnancy associated with new-onset hypertension, which occurs most often after 20 weeks of gestation and frequently near term, and proteinuria, or, in the absence of proteinuria, it is defined as new-onset hypertension with the new onset of any of the following: Thrombocytopenia: platelet count <100,000/milliliter (mL). Renal insufficiency: serum creatinine concentrations >1.1 milligram per deciliter (mg/dL) or a doubling of the serum creatinine concentration in the absence of other renal disease. Impaired liver function: elevated blood concentrations of liver transaminases to twice the normal concentration. Pulmonary edema. New-onset headache unresponsive to medication and not accounted for by alternative diagnoses or visual symptoms

From 20 weeks' gestation to pregnancy outcome
Number of participants (pregnant women) with eclampsia
Time Frame: From 20 weeks' gestation to pregnancy outcome

New-onset tonic-clonic, focal, or multifocal seizures in the absence of other causative conditions such as epilepsy, cerebral arterial ischemia and infarction, intracranial hemorrhage, or drug use.

From 20 weeks' gestation to pregnancy outcome
Number of participants (pregnant women) with gestational hypertension
Time Frame: From 20 weeks' gestation to pregnancy outcome

Blood pressure greater than 140 millimeter of mercury (mmHg) systolic or 90 mmHg diastolic on 2 separate occasions at least 4 hours apart after 20 weeks of pregnancy when previous blood pressure was normal.

From 20 weeks' gestation to pregnancy outcome
Number of participants (pregnant women) with gestational diabetes
Time Frame: At pregnancy outcome

Any degree of glucose intolerance with onset or first recognition during pregnancy.

At pregnancy outcome
Number of participants (pregnant women) with preterm births
Time Frame: At live birth, if occurring before 37 gestational weeks

Preterm birth is defined as a live birth occurring at <37 gestational weeks.

At live birth, if occurring before 37 gestational weeks
Number of infants with postnatal growth deficiency
Time Frame: At 4 and 12 months of infant age

Weight, length, or head circumference in <10th percentile for sex and chronological age using standard growth charts

At 4 and 12 months of infant age
Number of infants with developmental delay
Time Frame: At 4 and 12 months of infant age

Failure to achieve the developmental milestones for chronological age, as defined by the Centers for Disease Control and Prevention.

At 4 and 12 months of infant age
