Material Changes and Clinical Results
- ATLAS-2M Study Results: The Phase III ATLAS-2M study met its primary endpoint, demonstrating that a long-acting injectable regimen of cabotegravir and rilpivirine administered every eight weeks (two months) is non-inferior to the same regimen administered every four weeks (monthly) over a 48-week period.
- Study Population: The trial involved 1,045 adults living with HIV-1 infection who were virally suppressed and not resistant to the drugs.
- Primary Endpoint: Non-inferiority was assessed using the FDA Snapshot algorithm at Week 48, measuring the proportion of participants with plasma HIV-RNA ≥ 50 copies per milliliter.
- Safety Profile: Overall safety, virologic response, and drug resistance results for the every-two-months regimen were consistent with previous Phase III ATLAS study results.
Guidance, Outlook, and Management Commentary
Kimberly Smith, M.D., Head of Research & Development at ViiV Healthcare, stated that the results represent a significant shift in the HIV treatment paradigm, potentially reducing treatment frequency from 365 daily oral doses to six annual injections. The investigational regimen is being co-developed with Janssen Sciences Ireland UC and has been submitted to regulatory authorities in the United States, Canada, and Europe.
Regulatory Outlook: The FDA granted Priority Review Designation for the once-monthly injectable regimen, with an expected action date of December 29, 2019. Detailed results from the ATLAS-2M study are scheduled for presentation at an upcoming scientific meeting.
Risks: GSK includes a standard cautionary statement regarding forward-looking statements, noting that actual results may differ materially due to risks described in the company's 2018 Annual Report on Form 20-F.
Investor Verification Checklist
