ViiV Healthcare files submissions to the FDA and EMA for the first-ever dispersible formulation of dolutegravir (DTG) for children living with HIV

If approved, this new formulation of DTG will be the first integrase inhibitor available as a dispersible tablet for children living with HIV - closing the gap between treatment options available for adults and children

Issued: London, UK

ViiV Healthcare, the global specialist HIV company majority-owned by GSK, with Pfizer Inc. and Shionogi Limited as shareholders, today announced it has made regulatory submissions to both the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) seeking approval of the first-ever 5mg dispersible-tablet (DT) formulation of dolutegravir (DTG), as well as a simplified dosing regimen to optimise use of the existing DTG 50mg film-coated tablet (FCT) in paediatric HIV patients. The availability of age-appropriate formulations is essential in ensuring children around the world have access to optimal life-saving treatments.  

Paediatric HIV remains a global issue, with children disproportionately affected by the HIV epidemic. Latest statistics show there are 1.7 million children living with HIV[1], and the majority of AIDS-related deaths among children still occur during the first five years of life.[2] Major obstacles persist for children, such as the availability of HIV testing, continued mother-to-child transmission, slow initiation of treatment and poor availability of optimised paediatric formulations of antiretrovirals.[2,3]

Deborah Waterhouse, CEO of ViiV Healthcare, said: “For parents living in resource poor countries, the ability to give medicine to children in a format that they can swallow and tolerate can mean the difference between life and death.  By submitting these files to regulators for approval, we believe that we are on the cusp of delivering against our promise to develop dolutegravir in a tablet that can be dispersed simply in water. We will then aim to make this available, via partnerships, as quickly as possible to children living with HIV worldwide.”

These submissions to the EMA and FDA are based on data from the ongoing P1093[4] and ODYSSEY (PENTA20) studies.[5] Data to support the submissions has been generated from ViiV Healthcare’s collaborations with the U.S. National Institutes of Health (NIH) and the International Maternal Pediatric Adolescent AIDS Clinical Trials Network (IMPAACT) for P1093 and the Paediatric European Network for Treatment of AIDS (PENTA) for ODYSSEY. 

In order to support broad and more affordable access to optimised antiretroviral (ARV) formulations, ViiV Healthcare enables generic companies to manufacture and sell generic versions of paediatric DTG royalty-free in all least-developed, low-income, lower-middle-income and sub-Saharan African countries, as well as some upper-middle-income countries through its voluntary licensing policy. In addition to this, ViiV Healthcare has partnered with the Clinton Health Access Initiative (CHAI) and Unitaid since 2018 to expedite the development and introduction of optimised paediatric formulations of DTG by providing generic partners with financial and technical incentives to develop and manufacture it for resource-limited settings.

Sharon Nachman MD, Professor of Pediatrics at Stony Brook Children’s Hospital and Associate Dean for Research, Renaissance School of Medicine at Stony Brook University, USA, and Chair of The International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) Network, said: “It is always a significant achievement when we get to the stage where data from our trials is shared with regulatory authorities. Collaborating with ViiV Healthcare on the P1093 study has given us the opportunity to be involved with the progression of a new dispersible treatment option for children living with HIV. With relatively few therapies licensed to treat HIV in children, the availability of dolutegravir in this new formulation will allow us to expand our choice of antiretrovirals, taking us another step closer to our ultimate goal of achieving an AIDS-Free Generation.”

Notes to editors:

About P1093 and ODYSSEY[4, 5]

  • P1093 (NCT03016533): investigates the safety, pharmacokinetic, tolerability and antiviral activity of DTG regimens in paediatric patients aged four weeks to 18 years and is being conducted by the IMPAACT network in the U.S., Brazil, Thailand, South Africa, Zimbabwe, and Malawi.
  • ODYSSEY (PENTA20) (NCT02259127): is designed to understand how DTG as first- or second-line treatment compares to the current standards of care in paediatric patients aged four weeks to 18 years and is being conducted by the PENTA network in Europe, South America, Thailand, Uganda, Zimbabwe, and South Africa. Originally designed to support the World Health Organization (WHO) guideline recommendations by WHO weight bands, this study will now provide data to support this submission.

About dolutegravir

Dolutegravir (Tivicay) is an integrase strand transfer inhibitor (INSTI) for use in combination with other antiretroviral (ARV) agents for the treatment of HIV. Integrase inhibitors inhibit HIV integrase by binding to the integrase active site and blocking the strand transfer step of retroviral deoxyribonucleic acid (DNA) integration which is essential for the HIV replication cycle.

Tivicay is a registered trademark of the ViiV Healthcare group of companies. Discover the latest registration status of Tivicay worldwide.

Important Safety Information (ISI) for dolutegravir 10, 25, and 50 mg tablets

The following Important Safety Information is based on the Summary of Product Characteristics (SmPC) for dolutegravir (Tivicay). Please consult the full SmPC for the full safety information.

Indications and Usage

Dolutegravir is a human immunodeficiency virus type 1 (HIV-1) integrase strand transfer inhibitor (INSTI) indicated in combination with:

  • other ARV agents for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 30 kg
  • rilpivirine as a complete regimen for the treatment of HIV-1 infection in adults to replace the current ARV regimen in those who are virologically suppressed (HIV-1 RNA <50 copies per mL) on a stable ARV regimen for ≥6 months with no history of treatment failure or known substitutions associated with resistance to either ARV agent

Important Safety Information


  • Do not use dolutegravir in patients with previous hypersensitivity reaction to dolutegravir
  • Do not use dolutegravir in patients receiving dofetilide


Hypersensitivity Reactions:

  • Hypersensitivity reactions have been reported with dolutegravir and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury
  • Discontinue dolutegravir immediately if signs or symptoms of hypersensitivity reaction develop, as a delay in stopping treatment may result in a life-threatening reaction. Clinical status, including liver aminotransferases, should be monitored and appropriate therapy initiated


  • Hepatic adverse events have been reported, including cases of hepatic toxicity (elevated serum liver biochemistries, hepatitis, and acute liver failure) in patients receiving a dolutegravir-containing regimen without pre-existing hepatic disease or other identifiable risk factors
  • Patients with underlying hepatitis B or C or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations with use of dolutegravir. In some cases, the elevations in transaminases were consistent with immune reconstitution syndrome or hepatitis B reactivation, particularly in the setting where anti-hepatitis therapy was withdrawn
  • Monitoring for hepatotoxicity is recommended

Embryofetal Toxicity:

  • Alternative treatments to dolutegravir should be considered at the time of conception through the first trimester of pregnancy due to the risk of neural tube defects
  • Perform pregnancy testing before use of dolutegravir and counsel that consistent use of effective contraception is recommended while using dolutegravir in adolescents and adults of childbearing potential

Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions with concomitant use of dolutegravir and other drugs may result in known or potentially significant drug interactions (see Contraindications or Drug Interactions).

Immune Reconstitution Syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported with the use of dolutegravir.


The most common adverse reactions (incidence ≥2%, Grades 2-4) in treatment-naïve adults receiving dolutegravir in a combination regimen were insomnia (3%), headache (2%), and fatigue (2%).


  • Coadministration of dolutegravir with drugs that induce or inhibit UGT1A1 and/or CYP3A may affect plasma concentrations
  • Administer dolutegravir 2 hours before or 6 hours after taking antacids, polyvalent cation-containing products or laxatives, sucralfate, oral supplements containing iron or calcium, or buffered medications. Alternatively, oral calcium and iron supplements (including multivitamins containing calcium or iron) can be taken with dolutegravir if coadministered with a meal
  • Consult the full Prescribing Information for dolutegravir for more information on potentially significant drug interactions, including clinical comments


  • Pregnancy: There are insufficient human data on the use of dolutegravir during pregnancy to definitively assess a drug-associated risk for birth defects and miscarriage. An Antiretroviral Pregnancy Registry has been established. If planning a pregnancy or if pregnancy is confirmed while taking dolutegravir during the first trimester, assess the risks and benefits of continuing dolutegravir versus switching to another ARV regimen. For individuals actively trying to become pregnant, initiation of dolutegravir is not recommended unless there is no suitable alternative 
  • Lactation: Breastfeeding is not recommended due to the potential for HIV-1 transmission, developing viral resistance in HIV-positive infants, and adverse reactions in a breastfed infant
  • Females and Males of Reproductive Potential: Perform pregnancy testing before initiation of dolutegravir. Advise adolescents and adults of childbearing potential to consistently use effective contraception while taking dolutegravir
