Study summary

A randomised, open label, controlled PK standard of care vs doravirine plus 2 nucleoside reverse transcriptase inhibitors backbone in pregnant women initiating combination antiretroviral therapy in the second trimester of pregnancy.

Read the detailed description

Women diagnosed HIV positive in the second trimester of pregnancy in South Africa will be enrolled and randomised 1:1 to receive standard of care or doravirine plus 2 NRTI backbone. Participants will receive study treatment until delivery and up to 28 weeks postpartum, with a maximum total of 14 months of study treatment. Given the high prevalence of NNRTI resistance, alternative ARV treatment options are essential. Doravirine is licenced for the treatment of HIV-1 in adults in North America and Europe. Whilst the efficacy and safety of doravirine has been established in non-pregnant adults, there are no adequate human data available to establish whether DOR poses a risk to pregnancy outcomes. It is important to have data on the safety and pharmacokinetics of the drug during pregnancy and in particularly the third trimester of pregnancy in order to support its use. The hypothesis for this study is that pregnancy influences the pharmacokinetics of doravirine when initiated in the second trimester.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Women ≥ 18 years old
  • Ability to give prior to participation
  • Willing and able to comply with all study requirements
  • positive
  • Pregnant (initiating cART ≥ 12 weeks and \< 26 weeks gestation)
  • Intention to breastfeed postpartum

Exclusion criteria

Exclusion Criteria:

  • Received any cART in preceding 6 months
  • Chronic (HBV) infection with clinical evidence of transaminitis
  • Elevations in serum levels of (ALT) > 5 times the (ULN) or ALT > 3xULN and >2xULN (with > 35 % direct bilirubin)
  • Previous documented failure of an NNRTI-containing cART regimen
  • Previous history of to any ARV
  • Concomitant medication which are inducers of SoC and DOR metabolism (e.g. rifampicin, anti-epileptic agents, rifabutin, St John's Wort, mitotane, enzalutamide, lumacaftor). medications can be found on Liverpool Drug Interactions website (hiv-druginteractions.org)
  • Participants with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption cannot take DOR as the tablet contains lactose monohydrate
  • Clinical depression or clinical judgment suggests increased risk of suicidality
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
