Trial Overview

Outcome

Primary endpoint met - positive

Purpose

This non-inferiority phase III trial is evaluating the efficacy of a fixed dose combination (FDC) containing bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus a FDC containing abacavir/dolutegravir/lamivudine (ABC/DTG/3TC) in HIV-1 infected, antiretroviral treatment naive-adults.This trial includes an open-label extension phase.

Comments

According to a Gilead Sciences media release, Biktarvy (bictegravir 50mg/emtricitabine 200mg/tenofovir alafenamide 25mg, BIC/FTC/TAF), has been approved in China for the treatment of HIV-1 infection, based on the results of 4 trials (1489, 1490, 1844 and 1878).

In March 2019, the Japan's Ministry of Health, Labour and Welfare (MHLW) has approved Biktarvy (bictegravir 50mg/emtricitabine 200mg/tenofovir alafenamide 25mg, BIC/FTC/TAF), a once-daily single tablet regimen (STR) for the treatment of HIV-1 infection.
In 2018, the drug has also been approved by the Hong Kong Department of Health, the U.S. Food and Drug Administration (FDA) and the European Commission.
The approval of Biktarvy is supported by data from four Phase 3 studies (Studies 1489, 1490, 1844 and 1878).

Substudies/Extensions

An intensive pharmacokinetic (PK) substudy will be performed at the Weeks 4 or 8 visits in a subset of subjects (target n=30) at study sites able to conduct this testing. A pharmacogenomic substudy- For subjects who agree to participate and provide their additional specific consent, three blood samples will be obtained for the extraction of DNA for genomic testing and for potential genotyping to identify polymorphisms of drug metabolism enzymes including Uridine 5'-diphospho-glucuronosyltransferase (UGT1A1) and additional biomarker testing such as human leukocyte antigen (HLA). These samples will be collected at Day 1. A peripheral blood mononuclear cell (PBMC) substudy will be performed at Day 1 and Weeks 36, 84 and 132 in a subset of subjects (target n=50) at select study sites. The substudy will assess HIV-1, PBMC function for HIV disease progression, and how the immune system functions in the presence of HIV.
Beyond Week 144, study participants will have the option to receive Biktarvy in an open-label extension for up to 96 weeks.

Results

Therapeutic efficacy

Pooled four year follow-up results of the two phase III trials (study 1489 and study 1490) in HIV-infected antiretroviral treatment-naive patients showed that bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) was highly efficacious. Similar outcomes were demonstrated in participants who switched from dlutegravir/ abacavir/lamivudine (DTG/ABC/3TC)-containing regimens to B/F/TAF. The efficacy was >98% after week 48 at each study visit through week 192 in both studies. In participants initially randomised to B/F/TAF, the median change in weight from baseline to week 192 was 4.6 kg in study 1490 and 5.0 kg in study 1490. The mean percent changes (SD) in hip and spine bone mineral density (BMD) through week 192 were -1.5% (4.9) and -0.9% (5.2), respectively. At week 192, 13% of participants with baseline osteopenia in hip and 3% with osteopenia of the spine improved to normal, 4% with normal baseline hip and 6% with normal baseline spine BMD progressed to osteopenia and none developed osteoporosis [3] . Updated results from two phase III trial (study 1489 and study 1490) demonstrated that treatment with bictegravir/emtricitabine/ tenofovir (B/F/TAF) achieved high rates of viral suppression. Treatment outcomes by last on-treatment observation carried forward at week 144 for participants with and without transmitted drug resistance (TDR) was comparable (98% of those with primary TDR had HIV RNA <50 copies/mL vs. 97% of those without TDR). One participant had preexisting Q148H+G140S in IN and K70R and K103N in RT at baseline. This participant was randomized to B/F/TAF, had HIV-1 RNA <50 copies/mL at week 4 and maintained HIV-1 RNA <50 copies/mL through week 144. Out of 21 participants qualified for post-baseline resistance testing, 2/8 receiving B/F/TAF, 6/6 receiving dolutegravir/abacavir/lamivudine (DTG/ABC/3TC) and 4/7 receiving dolutegravir + emtricitabine/tenofovir (DTG + F/TAF) participants had multiple confirmed virologic rebounds during the studies. No participant had emergent resistance to study drugs [4] . Earlier results from the trials showed that through 144 weeks of therapy bictegravir/emtricitabine/tenofovir alafenamide was well-tolerated and demonstrated high rates of virologic suppression. At Week 144, non-inferiority was maintained from the primary endpoint measurement in both studies at Week 48, with a similar proportion of the Biktarvy group achieving virologic suppression (82 percent; n=518/634) as those taking DTG/ABC/3TC (84 percent; n=265/315) and DTG + F/TAF (84 percent; n=273/325). Across all treatment groups no participants developed treatment failure with treatment-emergent resistance. There were no discontinuations due to renal events and no cases of proximal renal tubulopathy or Fanconi syndrome in the Biktarvy treatment group. Similar reductions in median estimated glomerular filtration rate (eGFR) were observed across groups (-9.2 mL/min in patients taking Biktarvy vs. -11.7 mL/min in participants taking ABC/DTG/3TC versus -11.0 mL/min in participants taking DTG + F/TAF) at Week 144. Study 1489 also assessed other laboratory markers of renal and bone safety in patients taking Biktarvy and DTG/ABC/3TC. Participants in both treatment arms demonstrated similar median changes in proteinuria and mean percentage changes in hip and spine bone mineral density (BMD) from baseline. Small, statistically significant differences in the median change from baseline favoring DTG/ABC/3TC were observed for LDL, HDL and total cholesterol to HDL ratio [5] .

Pooled analysis: Pooled analysis of phase III trials 1489 and 1490 demonstrates that in both studies >98% of participants who initiated treatment with therapy bictegravir/emtricitabine/tenofovir alafenamide and remained in the study achieved and maintained an undetectable viral load (HIV-1 RNA <50 copies/mL) at four years of follow-up (n=235/237 for study 1489, n=241/243 for study 1490). The high efficacy and durable viral suppression were also observed in participants who switched to therapy bictegravir/emtricitabine/tenofovir alafenamide from a dolutegravir-containing triple therapy for the 48-week OLE periods (n=212 for study 1489, n=225 for study 1490). No treatment-emergent resistance to any components of the therapy occurred in participants treated with therapy bictegravir/emtricitabine/tenofovir alafenamide. The data from a 144 week analysis demonstrated that people living with HIV who received initial therapy with combination reached and maintained an undetectable viral load with no treatment-emergent resistance through 144 weeks (n=634). In a subgroup analysis of participants with transmitted drug resistance (TDR, n=248) based on retrospective sequencing from the baseline, combination therapy achieved comparably high levels of durable viral suppression through 144 weeks among participants with and without TDR (98% vs. 97%; as treated analysis). The data showed that of the 1240 patients who had shown confirmed suppression, 143 (11.5%) had 1 blip through week 144 with similar blip frequencies between treatment arms. Per study, an average of 1.3% of participants experienced blips. In 143 patients, total of 186 blip events were observed, 110 experienced a single blip and 33 experienced multiple blips. Of the 186 blips, 87 (46.8%) were low-level (50-199 c/mL) and 99 (53.2%) were 200 c/mL. Similarity was observed for proportions of participants with blips <200 c/mL or 200 c/mL. Most patients with blips 200 c/mL showed adherence 95% by pill count (69.2%), while those with blips <200 c/mL mostly showed adherence >95% (63.1%). Of participants without blips, 98.7% (1083/1097) showed HIV RNA <50 c/mL at week 144 or last visit versus, 91.0% (71/78) with blips 200 c/mL (p<0.01), or versus 96.9% (63/65) with blips <200 c/mL (P = 0.2). At week 144, 7 with blips 200 c/mL and HIV RNA 50 c/mL were on DTG-based regimens, and 6/7 had evidence of continued low adherence. Of 21 patients who underwent overall resistant analysis population, five patients showed blips [6] [7] .

Updated results from a phase III trial (Study 1489) in patients with HIV-1 infections showed that through 96 weeks of therapy bictegravir/emtricitabine/tenofovir alafenamide was statistically non-inferior to a regimen of abacavir/dolutegravir/lamivudine and non-inferiority was maintained from the primary endpoint measurement at week 48. At week 96, 87.9% (n = 276/314) of patients taking bictegravir/emtricitabine/tenofovir alafenamide (50/200/25mg) tablets and 89.8 % (n = 283/315) of patients taking abacavir/dolutegravir/lamivudine (600/50/300mg) achieved the primary endpoint of HIV-1 RNA levels less than 50 copies/mL (difference: -1.9%, 95 percent CI: -6.3 percent to 3.1%, p = 0.78). Significantly less median change in estimated glomerular filtration rate (eGFR) from baseline to week 96 was observed with bictegravir/emtricitabine/tenofovir alafenamide (-7.8 mL/min) compared with abacavir/dolutegravir/lamivudine (-9.6 mL/min) (p = 0.01). In both the treatment groups in changes from median changes in proteinuria were similar. Lipid changes were not significantly different between the two arms. Similar mean percent changes from baseline in spine and hip bone mineral density were observed in the bictegravir/emtricitabine/tenofovir alafenamide group and abacavir/dolutegravir/lamivudine group (spine: -0.71 vs. -0.22, p = 0.14; hip: -1.13 vs. -1.26, p = 0.59). The trial randomised 629 treatment-naïve adults with HIV to receive bictegravir/emtricitabine/tenofovir alafenamide or abacavir/dolutegravir/lamivudine [8] [9] .

Bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) 50mg/200mg/25mg met the primary endpoint of non-inferiority in all four phase III studies, with comparable proportions of patients having HIV-1 RNA < 50 copies/mL (Studies 1489 and 1490) and HIV-1 RNA ≥ 50 copies/mL (Studies 1844 and 1878). One patient randomised to the protease inhibitor arm in Study 1878 developed an abacavir resistance mutation (L74V). No patients randomised to the bictegravir or dolutegravir arms developed treatment-emergent resistance [1] .

Adverse events

Pooled four year follow-up results of the two phase III trials (study 1489 and study 1490) in HIV-infected antiretroviral treatment-naive patients showed long-term safety profile of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF). Across both studies, only one participant experienced an adverse events (AE) that led to drug discontinuation during the open-label extension (OLE) analysis window. Grade 3 or 4 drug-related AEs were rare. There were no discontinuations due to renal AEs [3] . Updated results from two phase III trials (Study 1489 and Study 1490) in patients with HIV-1 infections showed that through 144 weeks of therapy bictegravir/emtricitabine/tenofovir alafenamide was well-tolerated. Discontinuations due to adverse events were low across all groups (1% (n=6/634) for Biktarvy versus 2% (n=5/315) for DTG/ABC/3TC and 2% (n=6/325) for DTG + F/TAF). The proportion of drug-related adverse events (all grades) was 26% in the Biktarvy arm (n=165/634) versus 42% (n=132/315) for DTG/ABC/3TC and 29% (n=94/325) for DTG + F/TAF). The incidence of drug related nausea was 4% for Biktarvy versus 18% for DTG/ABC/3TC and 5% for DTG + F/TAF (p<0.0001 for Biktarvy versus DTG/ABC/3TC). The most commonly reported treatment-emergent adverse events (all grades) were diarrhoea (19% for Biktarvy versus 18% for DTG/ABC/3TC and 16% for DTG + F/TAF), headache (16% for Biktarvy versus 18% for DTG/ABC/3TC and 18% for DTG + F/TAF) and nasopharyngitis (14% for Biktarvy versus 17% for DTG/ABC/3TC and 19% for DTG + F/TAF) [5] .

Pooled analysis: Pooled analysis of phase III trials 1489 and 1490 showed that the most common adverse events (AEs) in adults of 50 years of age in patients receiving B/F/TAF, DTG/ABC/3TC, 325 DTG + F/TAF were nasopharyngitis (20%, 22%, 25%), diarrhea (19%, 22%, 8%), and upper respiratory tract infection (16%, 17%, 12%), respectively. The most common AEs in adults of <50 years of age were diarrhea (19%, 18%, 18%), headache (17%, 18%, 19%), and nausea (11%, 26%, 15%). Treatment-related AEs occurred in 24%, 37%, and 29% of participants the frequency was 26%, 43% and 29% in participants <50 years (p < 0.001 for B/F/TAF vs DTG/ABC/3TC). Most treatment related AEs were grade 1. 50 patients discontinued due to AEs, 2% on B/F/TAF, 5% on DTG/ABC/3TC and 7% on DTG + F/TAF compared to 1% in each treatment group for participants <50 years. Among 50 with AEs leading to discontinuation, 1 on B/F/TAF, 1 on DTG/ABC/3TC and 3 on DTG+F/TAF were treatment-related. 1274 were randomised and treated (634 Bictegravir/emtricitabine/tenofovir alafenamide [B/F/TAF], 315 Abacavir/Dolutegravir/Lamivudine [DTG/ABC/3TC], 325 Dolutegravir + Emtricitabine/Tenofovir Alafenamide[DTG + F/TAF]) [10] .

In a phase III trial (Study 1489), in patients with HIV-1 infections, the fixed dose combination of bictegravir/emtricitabine/tenofovir alafenamide was well tolerated through week 96. The most commonly reported adverse events with bictegravir/emtricitabine/tenofovir alafenamide and abacavir/dolutegravir/lamivudine were nausea (11% vs. 24%), diarrhoea (15% vs. 16%) and headache (13% vs. 16%), respectively. Discontinuations due to adverse events were low in both groups with only 2% (n = 5) reported in abacavir/dolutegravir/lamivudine arm and none in the bictegravir/emtricitabine/tenofovir alafenamide arm. None of the patients randomised to either arm developed treatment-emergent resistance. There were no renal discontinuations and no cases of proximal renal tubulopathy or fanconi syndrome in the bictegravir/emtricitabine/tenofovir alafenamide treatment group. The trial randomised 629 treatment-naïve adults with HIV to receive bictegravir/emtricitabine/tenofovir alafenamide or abacavir/dolutegravir/lamivudine [8] [9] .

In four phase III studies (Studies 1489, 1490, 1844 and 1878), bictegravir/emtricitabine/tenofovir alafenamide 50mg/200mg/25mg was well tolerated. Treatment-emergent virological resistance was not seen. No patients discontinued study medication due to renal events and no cases of proximal renal tubulopathy or Fanconi syndrome were observed. Diarrhoea, nausea and headache were the most common adverse reactions [1] .
