Safety and Efficacy of B/F/TAF in Pregnancy

18 de junho de 2026 atualizado por: Shi Zou

Effectiveness and Safety of Bictegravir/Emtricitabine/Tenofovir Alafenamide in Pregnant Women With HIV Infection（BIP STUDY）.

This is a prospective, multicenter, observational study designed to evaluate the effectiveness and safety of Bictegravir/Emtricitabine/Tenofovir Alafenamide (B/F/TAF) in pregnant women living with HIV. Given the limited prospective data on B/F/TAF use during early pregnancy, this study aims to address the evidence gap by observing women who are on B/F/TAF for at least six months with sustained viral suppression (HIV RNA <50 copies/mL) and are within the first trimester. Participants will continue B/F/TAF throughout pregnancy and up to 12 weeks postpartum per routine clinical practice. No experimental intervention will be assigned. The primary objective is to assess the proportion of participants achieving HIV RNA <50 copies/mL at 12 12 weeks of pregnancy. Secondary objectives include maternal viral suppression at 28 weeks, delivery, and postpartum; safety and tolerability; maternal and neonatal outcomes including congenital anomalies, APGAR scores, infant HIV status, and growth parameters. The study will enroll at least 50 participants across five clinical centers in China. Findings will provide real-world evidence on the use of B/F/TAF as an alternative integrase inhibitor-based regimen for pregnant women with HIV.

Descrição detalhada

Statistical Methods Descriptive statistics will be used to summarize the data. Continuous variables will be presented as means with standard deviations and medians with interquartile ranges, depending on the distribution of the data. Categorical variables will be described by their frequency distribution and ranges (Two-sided 95% confidence).

Efficacy:

The proportion of participants with plasma HIV RNA <50 copies/mL at the time of delivery will be summarized using the missing = excluded approach for imputing missing HIV RNA values.

Safety:

The adverse events (AE) data will be listed by subject. Treatment-emergent AEs, Grade 1-4 AEs will be summarized by system organ class, and preferred term using the current version of the Medical Dictionary for Regulatory Activities (MedDRA), and graded according to the DIADS Table for Grading the Severity of Adult and Pediatric Adverse Events .

Listings of individual subject vital signs, 12-lead ECG parameters, and laboratory results will be provided. Laboratory abnormalities will be graded for severity using the DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events. Laboratory results and changes from baseline for vital signs and selected lab tests will be summarized at scheduled visits. The incidence and grade of treatment-emergent laboratory abnormalities will be summarized accordingly.

Maternal/neonatal outcomes analysis Proportion of infants with confirmed negative or positive HIV RNA testing will be summarized using the missing = excluded approach for imputing missing HIV RNA values.

Proportion of live births, stillbirths, and pregnancy loss will be summarized. APGAR scores will be summarized. Adverse events and toxicity management

Definitions of Adverse Events, Adverse Reactions, and Serious Adverse Events:

Adverse Events An AE is any untoward medical occurrence in a clinical study subject administered a pharmaceutical product, which does not necessarily have a causal relationship with the treatment. An AE can therefore be any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. AEs may also include lack of efficacy, overdose, drug abuse/misuse reports, or occupational exposure.

O que o estudo está medindo?

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Proportion of Participants with HIV RNA <50 Copies/mL at 12 Weeks of Pregnancy
Prazo: 12 weeks of pregnancy.
The proportion is calculated using the Missing=Excluded approach (participants with missing HIV RNA values at the 12-week time point are excluded from both numerator and denominator).
12 weeks of pregnancy.

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Maternal Plasma HIV RNA Level
Prazo: 28 weeks of pregnancy, at delivery, and 2-12 weeks postpartum
HIV RNA levels are measured in copies/mL. Descriptive statistics (geometric mean, median, and interquartile range) will be reported at each specified time point.
28 weeks of pregnancy, at delivery, and 2-12 weeks postpartum
Number of Participants with Treatment-Emergent Grade 3 or 4 Adverse Events

Occurrence of Congenital Anomalies
Prazo: From birth through 12 weeks postpartum
Congenital anomalies are identified through prenatal ultrasound examinations, prenatal diagnostics (e.g., amniocentesis with genetic/epigenetic testing), and postnatal physical examination. Each anomaly is reported as a separate event.
From birth through 12 weeks postpartum
Pregnancy Outcome: Live Birth vs. Fetal Loss/Stillbirth
Prazo: At delivery

At delivery
Infant APGAR Score
Prazo: At 1 minute and 5 minutes after delivery
APGAR score is assessed at 1 and 5 minutes post-delivery. Scores range from 0 to 10, with higher scores indicating better condition. If asphyxia is present, an additional assessment is performed at 10 minutes. Descriptive statistics (mean, standard deviation, median, range) will be reported for each time point.
At 1 minute and 5 minutes after delivery
Number of Infants with Confirmed Positive HIV RNA Test Result
Prazo: From birth through 12 weeks of age
HIV RNA testing is performed at birth, 6 weeks of age, and 12 weeks of age. A confirmed positive result requires two consecutive positive tests. Infants with negative or indeterminate results at all time points are considered uninfected.
