Dolutegravir (DTG), sold under the brand name Tivicay, is an antiretroviral medication used, together with other medication, to treat HIV/AIDS.[4] It may also be used, as part of post exposure prophylaxis, to prevent HIV infection following potential exposure.[5] It is taken by mouth.[4]

Common side effects include trouble sleeping, feeling tired, diarrhea, high blood sugar, and headache.[5] Severe side effects may include allergic reactions and liver problems.[5] There are tentative concerns that use during pregnancy can result in harm to the baby.[5] It is unclear if use during breastfeeding is safe.[5] Dolutegravir is an HIV integrase strand transfer inhibitor which blocks the functioning of HIV integrase which is needed for viral replication.[5]

Dolutegravir was approved for medical use in the United States in 2013.[5] It is on the World Health Organization's List of Essential Medicines.[6] Abacavir/dolutegravir/lamivudine, a combination with abacavir and lamivudine is also available.[5][7][8] As of 2019, the World Health Organization (WHO) recommends DTG as the first- and second-line treatment for all persons with HIV.[9]

Medical use

Dolutegravir is approved for use in a broad population of HIV-infected patients. It can be used to treat HIV-infected adults who have never taken HIV therapy (treatment-naïve) and HIV-infected adults who have previously taken HIV therapy (treatment-experienced), including those who have been treated with other integrase strand transfer inhibitors. Tivicay is also approved for children ages 12 years and older weighing at least 40 kilograms (kg) who are treatment-naïve or treatment-experienced but have not previously taken other integrase strand transfer inhibitors.[10]

In the European Union it is indicated, in combination with other anti-retroviral medicinal products, for the treatment of Human Immunodeficiency Virus (HIV) infected adults, adolescents and children above six years of age.[3]

In June 2020, the indication for dolutegravir in the US was updated to include children at least four weeks old and weighing at least 3 kg (6.61 pounds).[11]

Adverse effects

Common side effects of dolutegravir in clinical trials included insomnia and headache. Serious side effects included allergic reactions and abnormal liver function in patients who were also infected with hepatitis B or C.[12] The package insert warns against a mean rise in serum creatinine of 0.11 mg/dL due to inhibition of tubular secretion of creatinine and does not affect GFR.[2]

Pregnancy

There are tentative concerns that use during pregnancy can result in harm to the baby.[5] Effective birth control is thus recommended while on dolutegravir, with pregnancy testing before starting treatment.[13] Use during the first trimester should only occur if there is no alternative.[13]

History

In February 2013, the U.S. Food and Drug Administration (FDA) announced that it would fast track dolutegravir's approval process.[14] On August 13, 2013, dolutegravir was approved for medical use in the United States.[15] On November 4, 2013, dolutegravir was approved by Health Canada.[16] On January 16, 2014, it was approved by the European Commission for use throughout the European Union.[3]

In 2019, a triple-combination therapy, with dolutegravir replacing efavirenz, was introduced as the first-line treatment for all people (pregnant excluded) with HIV by the South African Government (public) sector.[medical citation needed]

In June 2020, dolutegravir was approved in the US with an indication to treat HIV-1 infection in children at least four weeks old and weighing at least 3 kg (6.61 pounds) in combination with other antiretroviral treatments.[11] It is intended to treat children at least 4 weeks old and 3 kg who have never been treated for HIV or who have been treated, but not with an integrase strand transferase inhibitor (INSTI) class drug.[11][17]

The U.S. Food and Drug Administration (FDA) granted the approval of Tivicay and Tivicay PD to ViiV Healthcare.[11]
