Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

Clinical Trials In Adults With No Antiretroviral Treatment History

The safety assessment of DOVATO in HIV-1-infected adults with no antiretroviral treatment history and with a plasma viral load ≤500,000 HIV-1 RNA copies/mL at the screening visit, is based on the pooled primary Week 96 analyses of data from 2 identical, multicenter, double-blind, controlled trials, GEMINI-1 and GEMINI-2. A total of 1,433 HIV-1-infected adults with no antiretroviral treatment history received either dolutegravir (TIVICAY) 50 mg plus lamivudine (EPIVIR) 300 mg, as a complete regimen once daily, or TIVICAY 50 mg plus fixed-dose combination tenofovir disoproxil fumarate (TDF)/emtricitabine (FTC) (TRUVADA), administered once daily.

The rates of adverse events leading to discontinuation in the pooled analysis were 3% of subjects in both treatment arms. The most common adverse events leading to discontinuation were psychiatric disorders: 1% of subjects in both treatment arms.

Adverse reactions (all grades) observed in at least 2% of subjects in either treatment arm of the Week 96 pooled analysis from GEMINI-1 and GEMINI-2 trials are provided in Table 2.

The adverse reactions observed for TIVICAY plus EPIVIR in the Week 96 analysis of the pooled data from GEMINI-1 and GEMINI-2 were generally consistent with the adverse reaction profiles and severities for the individual components when administered with other antiretroviral agents.

Table 2: Adverse Reactions (All Grades) Reported in ≥2% of Subjects in Any Treatment Group in Adults with No Antiretroviral Treatment History in GEMINI-1 and GEMINI-2 (Week 96 Pooled Analysis)

Adverse Reaction TIVICAY plus EPIVIR
(n = 716)
(n = 717)
Headache 3% 4%
Nausea 2% 5%
Diarrhea 2% 3%
Insomnia 2% 3%
Fatiguea 2% 2%
Anxiety 2% 1%
Dizziness 1% 2%
a Fatigue: includes fatigue, asthenia, and malaise.

Adverse reactions of at least Grade 2 occurring in ≥1% of subjects treated with TIVICAY plus EPIVIR were headache, anxiety, and suicidal ideation (all at 1%).

Less Common Adverse Reactions

The following adverse reactions occurred in <2% of subjects receiving dolutegravir plus lamivudine or are from studies described in the prescribing information of the individual components, TIVICAY (dolutegravir) and EPIVIR (lamivudine). Some events have been included because of their seriousness and assessment of potential causal relationship.

Blood and Lymphatic Systems Disorders: Anemia, neutropenia, thrombocytopenia.

Gastrointestinal Disorders: Abdominal discomfort, abdominal pain, flatulence, upper abdominal pain, vomiting.

General: Fever.

Hepatobiliary Disorders: Hepatitis.

Immune System Disorders: Hypersensitivity, immune reconstitution syndrome.

Musculoskeletal Disorders: Myositis.

Nervous System Disorders: Somnolence.

Psychiatric Disorders: Abnormal dreams, depression. Suicidal ideation, attempt, behavior, or completion; these events were observed primarily in subjects with a pre-existing history of depression or other psychiatric illness.

Renal and Urinary Disorders: Renal impairment.

Skin and Subcutaneous Tissue Disorders: Pruritus, rash.

Clinical Trials In Virologically Suppressed Adults

The safety of DOVATO in virologically suppressed adults was based on Week 48 data from 740 subjects in a randomized, parallel-group, open-label, multicenter, non-inferiority controlled trial (TANGO). Subjects who were on a stable suppressive tenofovir alafenamide-based regimen (TBR) were randomized to receive DOVATO once daily or continue with their TBR for up to 200 weeks. Overall, the safety profile of DOVATO in virologically suppressed adult subjects in the TANGO trial was similar to that of TIVICAY plus EPIVIR in subjects with no antiretroviral treatment history in the GEMINI trials [see Clinical Studies].

Laboratory Abnormalities

Selected laboratory abnormalities with a worsening grade from baseline and representing the worst-grade toxicity are presented in Table 3. The mean change from baseline observed for selected lipid values is presented in Table 4.

a Subjects on lipid-lowering agents at baseline are excluded (TIVICAY plus EPIVIR, n = 30; TIVICAY plus TRUVADA, n = 23). The last available fasted, on-treatment lipid value prior to initiation of a lipid-lowering agent was carried forward in place of observed values after initiation of a lipid-lowering agent. A total of 40 and 16 subjects receiving TIVICAY plus EPIVIR and TIVICAY plus TRUVADA, respectively, initiated lipid-lowering agents post-baseline.

Changes In Serum Creatinine

Dolutegravir has been shown to increase serum creatinine due to inhibition of tubular secretion of creatinine without affecting renal glomerular function [see CLINICAL PHARMACOLOGY]. Increases in serum creatinine occurred within the first 4 weeks of treatment in both arms and remained stable through 96 weeks. A mean change from baseline of 0.138 mg/dL and 0.176 mg/dL was observed after 96 weeks of treatment with TIVICAY plus EPIVIR and TIVICAY plus TRUVADA, respectively. These changes are not considered to be clinically relevant.

Postmarketing Experience

The following adverse reactions have been identified during postmarketing experience in patients receiving a dolutegravir-or lamivudine-containing regimen. Because postmarketing reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Body as a Whole

Redistribution/accumulation of body fat.

Endocrine and Metabolic




Hemic and Lymphatic

Anemia (including pure red cell aplasia and severe anemias progressing on therapy).

Hepatic and Pancreatic

Lactic acidosis and hepatic steatosis [see WARNINGS AND PRECAUTIONS], pancreatitis, posttreatment exacerbations of HBV [see WARNINGS AND PRECAUTIONS].

Hepatobiliary Disorders

Acute liver failure, hepatotoxicity.


Anaphylaxis, urticaria.


Weight increased.


Arthralgia, CPK elevation, muscle weakness, myalgia, rhabdomyolysis.

Nervous System

Paresthesia, peripheral neuropathy.




Coadministration With Other Antiretroviral Drugs

DOVATO is a complete regimen for the treatment of HIV-1 infection; therefore, coadministration with other antiretroviral drugs for the treatment of HIV-1 infection is not recommended [see INDICATIONS AND USAGE]. Information regarding potential drug-drug interactions with other antiretroviral drugs is not provided [see CONTRAINDICATIONS, WARNINGS AND PRECAUTIONS, CLINICAL PHARMACOLOGY].

Potential For DOVATO To Affect Other Drugs

Dolutegravir, a component of DOVATO, inhibits the renal organic cation transporters (OCT)2 and multidrug and toxin extrusion transporter (MATE)1; thus, it may increase plasma concentrations of drugs eliminated via OCT2 or MATE1 such as dofetilide, dalfampridine, and metformin [see CONTRAINDICATIONS, DRUG INTERACTIONS, CLINICAL PHARMACOLOGY].

Potential For Other Drugs To Affect The Components Of DOVATO

Dolutegravir is metabolized by uridine diphosphate (UDP)-glucuronosyl transferase (UGT)1A1 with some contribution from cytochrome P450 (CYP)3A. Dolutegravir is also a substrate of UGT1A3, UGT1A9, breast cancer resistance protein (BCRP), and P-glycoprotein (P-gp) in vitro. Drugs that induce those enzymes and transporters may decrease dolutegravir plasma concentrations and reduce the therapeutic effect of DOVATO [see DRUG INTERACTIONS, CLINICAL PHARMACOLOGY]. Coadministration of DOVATO and other drugs that inhibit these enzymes may increase dolutegravir plasma concentrations.

Coadministration of dolutegravir with polyvalent cation-containing products may lead to decreased absorption of dolutegravir [see DRUG INTERACTIONS, CLINICAL PHARMACOLOGY].

Established And Other Potentially Significant Drug Interactions

No drug interaction studies were conducted with DOVATO. The drug interactions described are based on studies conducted with dolutegravir or lamivudine when administered alone [see CLINICAL PHARMACOLOGY]. Information regarding potential drug interactions with DOVATO are provided in Table 5. These recommendations are based on either drug interaction trials or predicted interactions due to the expected magnitude of interaction and potential for serious adverse events or loss of efficacy [see CONTRAINDICATIONS, CLINICAL PHARMACOLOGY].

Table 5: Established and Other Potentially Significant Drug Interactions for DOVATO: Alterations in Dose May Be Recommended Based on Drug Interaction Trials or Predicted Interactions

Coadministered Drug Class: Drug Name Effect on Concentration Clinical Comment
↑Dofetilide Coadministration is contraindicated with DOVATO [see CONTRAINDICATIONS].
Anticonvulsant: Carbamazepinea ↓Dolutegravir An additional dolutegravir 50-mg dose should be taken, separated by 12 hours from DOVATO [see DOSAGE AND ADMINISTRATION].
Anticonvulsants: Oxcarbazepine
↓Dolutegravir Avoid coadministration with DOVATO because there are insufficient data to make dosing recommendations.
↑Metformin Refer to the prescribing information for metformin for assessing the benefit and risk of concomitant use of DOVATO and metformin.
↓Dolutegravir An additional 50-mg dose of dolutegravir should be taken, separated by 12 hours from DOVATO [see DOSAGE AND ADMINISTRATION].
Herbal product: St. John’s wort (Hypericum perforatum) ↓Dolutegravir Avoid coadministration with DOVATO because there are insufficient data to make dosing recommendations.
Medications containing polyvalent cations (e.g., Mg or Al): Cation-containing antacidsa or laxatives
