Janssen Presents New Data from First Phase 3 Trial of a Single-Tablet Regimen in a Rapid Initiation Model of Care Demonstrating Safety and Efficacy with SYMTUZA® through 48 Weeks

 

High Proportion of Patients Achieve Undetectable Viral Loads after Rapidly Starting SYMTUZA®(1)

 

MIAMI, April 11, 2019 /PRNewswire/ — The Janssen Pharmaceutical Companies of Johnson & Johnson unveiled new 48-week data for SYMTUZA® (darunavir 800 mg, cobicistat 150 mg, emtricitabine 200 mg and tenofovir alafenamide 10 mg D/C/F/TAF) showing that a high proportion of HIV patients achieved an undetectable viral load through 48 weeks after rapidly starting SYMTUZA®. A secondary endpoint of the study also showed that 97% of patients reported they were satisfied with their treatment.1 The results from the DIAMOND study – the first prospective Phase 3 trial studying the rapid initiation of a single-tablet regimen (STR) – were presented at the 13th Annual American Conference for the Treatment of HIV (ACTHIV 2019) in Miami, Florida.

The DIAMOND study evaluated the once-daily STR SYMTUZA® for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adult patients who were enrolled within 14 days of receiving an HIV diagnosis and then started on SYMTUZA® before laboratory or baseline resistance test results were available.1 SYMTUZA® is approved by the U.S. Food & Drug Administration (FDA) for the treatment of HIV-1 infection in treatment-naïve and certain virologically suppressed adults.

“Rapid initiation of antiretroviral treatment is becoming the recognized standard of care for newly diagnosed HIV-1 patients, as it has the potential to improve treatment outcomes, including the probability of a person adhering to treatment and staying in care, and could be an additional strategy in our quest to achieve the 90/90/90 prevention and treatment goals as outlined by UNAIDS,” said Moti Ramgopal, M.D., Infectious Disease Director, Midway Immunology and Research Center, Fort Pierce, Florida.* “The DIAMOND study is the first evidence-based STR-specific trial in a rapid initiation model of care. SYMTUZA® was well-tolerated, and a high proportion of patients achieved undetectable viral loads of less than 50 c/mL after 48 weeks.”   

DIAMOND is a Phase 3, single-arm, open-label, prospective, multicenter 48-week study evaluating the efficacy and safety of rapidly initiating SYMTUZA®.1 These 48-week data, which follow on from the interim 24-week results presented at the 2018 International AIDS Conference (AIDS 2018), confirm the safety, efficacy and tolerability profile of rapidly starting SYMTUZA® as a treatment for antiretroviral treatment (ART)-naïve adults with HIV-1.1

Through 48 weeks, almost 90% (97/109) of patients enrolled in DIAMOND completed the study.1 In the primary intent-to-treat (ITT) analysis, 84% (92/109) of patients achieved undetectable viral loads (viral load <50 c/mL; FDA-snapshot), and 8% (9/109) of patients had virologic failure (viral load ≥50 c/mL; FDA-snapshot) at 48 weeks.1

Additionally, in an observed analysis – which excluded those with missing data – 96% (92/96) of patients achieved undetectable viral loads, and 100% (96/96) of patients achieved viral loads of <200 c/mL at Week 48, with no patients discontinuing treatment with SYMTUZA® due to lack of efficacy.1 

SYMTUZA® was well-tolerated with no serious related adverse events (AEs). Most AEs were grade 1 or 2 in severity, and only two patients experienced a grade 3 drug-related AE, with one patient discontinuing the trial due to adverse events.1 The most common adverse drug reactions related to SYMTUZA® (all grades, ≥2% of adults) were diarrhea, nausea, rash, vomiting and fatigue.1 Grade 3 and 4 laboratory abnormalities, occurring in ≥2% of patients, included increases in aspartate aminotransferase (5%), alanine aminotransferase (3%) or bilirubin (3%).1

Prior to or when initiating SYMTUZA®, patients should undergo testing for hepatitis B virus (HBV) and renal function. Appropriate laboratory tests, including liver testing, hepatitis serology and HIV genotypic resistance testing, should be conducted, and patients should be monitored during treatment as clinically appropriate.1

As another key endpoint, the DIAMOND study also collected the first-known patient-reported outcomes in a Phase 3 rapid initiation trial via a validated HIV Treatment Satisfaction Questionnaire. On a 60-point scale, patients in the DIAMOND trial consistently reported high satisfaction scores (average scores ranging from 56 to 58) regarding treatment with SYMTUZA®.1 When asked specifically about their current treatment (SYMTUZA®), 97% of patients reported they were satisfied with their treatment.1

“When you’re first diagnosed with HIV, your entire world changes, and there are so many questions and uncertainties. However, one thing I did know was that getting on treatment as soon as possible was the most important thing for me to do so I could keep living,” said Brandon B., DIAMOND clinical trial patient. “As a participant in the DIAMOND trial, I was grateful for the opportunity to make treatment part of my daily routine with SYMTUZA®.”

Darunavir has been studied in more than 5,500 patients in 14 clinical trials with data up to 192 weeks.2,3 The U.S. Department of Health and Human Services (DHHS) guidelines recommend darunavir-based regimens, such as SYMTUZA®, for patients who may require the rapid initiation of ART before full blood work is available.4 The International Antiviral Society (IAS)-USA guidelines also recommend darunavir-based regimens for rapidly initiating treatment.5 Additionally, the DHHS guidelines recommend darunavir-based regimens for those who may have suboptimal adherence and face the risk of developing HIV drug resistance, which is when a medication stops working to fight the virus.4

Several studies examining rapid initiation in newly diagnosed adults with HIV-1 have previously underscored the benefits of linking people with HIV to treatment services soon after diagnosis, including improved virologic outcomes, retention in care and decreased morbidity/mortality.6,7,8 While achieving viral suppression is always a main goal of treatment for individuals, these studies have also found that rapid initiation may get patients to undetectable viral loads more quickly and sustain them over time.

“At Janssen, we’re committed to the research and development of medicines and solutions that have the potential to change the treatment paradigm for people living with HIV – across the care continuum,” said Richard Nettles, M.D., Vice President, Medical Affairs, Janssen Infectious Diseases, Janssen Scientific Affairs, LLC. “The DIAMOND study mirrors real clinical scenarios that physicians face today – including the need to start treatment before lab or baseline resistance test results are available – and highlights the benefits this model of care can bring to those newly diagnosed with HIV. SYMTUZA® is the only single-tablet regimen proven in a Phase 3 clinical trial studying the rapid initiation of treatment, further demonstrating it as a treatment option for people new to HIV therapy.”

SYMTUZA® was approved by the U.S. Food & Drug Administration (FDA) in July 2018 for treatment-naïve and certain virologically suppressed adults. The approval was based on the results from the two pivotal Phase 3 studies, EMERALD and AMBER.9,10  Ninety-six-week results from the Phase 3 EMERALD and AMBER trials were presented at IDWeek and the HIV Glasgow Congress, respectively, in Fall 2018.11,12

SYMTUZA® has also been approved by the European Commission (EC) and Health Canada for the treatment of HIV-1 infection in adults and adolescents aged 12 years and older with body weight of at least 40 kg. European approval allows Janssen to market SYMTUZA® in all member states of the European Union and the European Economic Area. Janssen plans additional regulatory filings in other markets worldwide. 

SYMTUZA® does not cure or prevent HIV-1 or AIDS.

About DIAMOND1

DIAMOND is a Phase 3, single‐arm, open‐label, prospective, multicenter, 48-week study assessing the efficacy/safety of rapidly initiating SYMTUZA® 800/150/200/10 mg. Adults diagnosed with HIV‐1 infection within 14 days were enrolled and started on SYMTUZA® without screening/baseline laboratory or HIV genotypic resistance information available. Investigators reviewed screening/baseline laboratory and resistance findings as results became available; patients not meeting predefined safety or resistance stopping rules continued treatment.

Resistance was evaluated based on predicted genotypic sensitivity (there was no exclusion based on the presence of specific resistance-associated mutations). Patients who did not show full genotypic sensitivity to the components of SYMTUZA® (assessed using GenoSure PRIme®) would be required to stop the study; an exception was resistance to lamivudine/emtricitabine associated with the M184I or V mutation alone.

Screening/baseline safety laboratory findings were evaluated on Day 3 (±1 week), with the following stopping criteria:

  • eGFR (MDRD formula) <50 mL/min
  • Aspartate aminotransferase or alanine aminotransferase ≥2.5 times the upper limit of normal (ULN)
  • Serum lipase ≥1.5 times the ULN
  • Positive pregnancy test for women of childbearing potential
  • Laboratory results that the investigator believes should result in discontinuation of study medication
  • Active hepatitis C infection that required immediate treatment or is expected to require treatment during the study with agents not compatible with SYMTUZA®
