NCT04998838

Brief Summary

Single arm, prospective open-label study of a care model consisting of two components: Component I aims to achieve high coverage of interventions to prevent maternal-to-child transmission of hepatitis B virus: antenatal tenofovir, and timely newborn administration of hepatitis B birth dose vaccine and hepatitis B immune globulin; Component II aims to achieve high coverage of screening, vaccination, and anti-viral therapy for HBV among household members of women with chronic HBV infection.

Outcome Measures

Primary Outcomes (3)

  • Vaccine within 24 hours

    Proportion of newborns of HBsAg positive mothers receiving HBV vaccine within 24 hours of birth

    Within 24 hours of birth

  • Effective treatment of pregnant women

    Proportions of pregnant women with chronic HBV (HBsAg positive) who are (a) linked to care (attend BK Kee Clinic for assessment of treatment eligibility); (b) complete TDF eligibility testing; (c) initiate tenofovir treatment (TDF, among those eligible); (d) adhere to TDF treatment until delivery and (e) continue treatment until 4 weeks post-partum o Low/medium/high high medication adherence are defined, respectively, as ≤6, 6-7 or 8 points on the Morisky Medication Adherence Scale (MMAS-8)

    During pregnancy (until delivery) of each woman, average of 9 months

  • Household contact screening

    Proportions of adult household contacts who (a) are screened for chronic HBV infection and immunity (HBsAg/Ab); (b) are linked to care (among HBsAg positive) or vaccinated (if HBsAb negative); (c) complete appropriate testing for hepatocellular carcinoma (HCC) screening, (d) eligible for TDF treatment; (e) initiate chronic HBV treatment with TDF

    Upon identification of participating women, until the end of the project, average of 1 year

Secondary Outcomes (7)

  • Total screening of mothers

    During pregnancy (until delivery) of each woman, average of 9 months

  • Antenatal care for HBV positive pregnant mothers

    During pregnancy (until delivery) of each woman, average of 9 months

  • Vaccination of HBV negative pregnant mothers

    During pregnancy (until delivery) of each woman, average of 9 months

  • Treatment of high viral load pregnant mothers

    At delivery; during antenatal care testing; at 4 months postpartum, throughout the project, average of 12 months

  • Viral suppression

    At delivery, throughout the project (one off)

  • +2 more secondary outcomes

Other Outcomes (4)

  • Completed vaccination courses

    Before age 1, average of 1 year

  • Proportion of pregnant women with HBsAg identified by surveillance team members

    During pregnancy, average of 9 months

  • Timeliness of pregnancy surveillance

    During pregnancy, average of 9 months

  • +1 more other outcomes

Study Arms (1)

Tenofovir Disoproxil Fumerate

EXPERIMENTAL

Pregnant women (\>=20 weeks of gestation) will be treated with TDF if clinically eligible; newborns will receive birth dose vaccine (and HBIG if eligible). Non-eligible women will be treated according to normal practices; newborns will still receive birth dose vaccine.

Drug: Tenofovir Disoproxil Fumarate 300 mg daily; HBV birth dose vaccine; hepatitis B immune globulin (HBIG)Drug: Regular Myanmar treatment

Interventions

Antenatal screening for HBV, anti-viral treatment with tenofovir according to treatment eligibility criteria, and birth dose vaccination at delivery to prevent mother-to-child transmission of HBV

Also known as: Viread
Tenofovir Disoproxil Fumerate

Treated according to normal Myanmar processes for HBV positive patients

Tenofovir Disoproxil Fumerate

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Pregnant women \>= 18 years of age
  • Gestational age =\<34 weeks
  • Test positive for HBsAg
  • Live in study site area in South Dagon and Dagon Seikkan Townships, Yangon Region
  • Give informed consent to participate in the study

You may not qualify if:

  • Alanine aminotransferase (ALT) levels \>300 IU/L
  • For qualitative study:
  • Key informants (e.g., healthcare providers and community leaders in the study area) OR
  • HBsAg+ women and their household members in the study area
  • HBsAg- women and their household members in the stud area
  • Give informed consent to participate in the study
  • History of renal dysfunction
  • CrCL \< 50mL/min
  • ALT\>5 times the upper limit of normal (ULN)
  • Evidence of decompensated cirrhosis (e.g., jaundice, ascites, history of upper gastrointestinal bleeding/esophageal varices, and hepatic encephalopathy)
  • Any concomitant condition or treatment that, in view of the clinical site investigator, would contraindicate participation or satisfactory follow-up in the study HIV positive status unless 1) they are currently on additional ART therapy, or 2) their viral load is demonstrated to be \<50 copies. Women who are newly diagnosed with HIV and referred to start a TDF-based regimen may be considered eligible once they have started the TDF-based regimen.
  • Concurrent participation in any other clinical trial without written agreement of the study team
  • Does not intend to deliver within catchment area, and/or intends to migrate before newborn follow-up is complete
