Recent FDA approval of ViiV Healthcare’s HIV treatment Cabenuva reduced dosing to once every two months.
ViiV Healthcare’s HIV treatment Cabenuva has been approved by the U.S. Food and Drug Administration for use every two months, meaning patients only have to receive an injectable dose six times per year.
Cabenuva was first approved last year for use once a month, reducing antiretroviral treatments from once per day to only 12 times per year. Cabenuva (cabotegravir, rilpivirine) has been designed to replace antiretroviral regimens currently used by some HIV-positive adults whose disease is virologically suppressed.
ViiV Healthcare, established through a partnership of GlaxoSmithKline, Pfizer and Shinogi Limited, is laser-focused on developing new therapeutics for HIV, a disease that has been present in society for the past 41 years. The recent FDA approval for Cabenuva allows for monthly or every other month dosing.
The latest approval was based on data from the Phase IIIb ATLAS-2M study that showed dosing of Cabenuva every other month was non-inferior to monthly dosing. The study also found that rates of virologic suppression were similar for dosing monthly or every two months. This was a key secondary endpoint of the Phase IIIb study. Cabenuva continued to show a safe profile in HIV patients with adverse events primarily limited to injection site reaction, fatigue, dizziness, and musculoskeletal pain.
Lynn Baxter, head of North America at ViiV Healthcare, expressed excitement about the latest approval for Cabenuva.
“Today’s approval is a remarkable achievement given where HIV treatment was just a decade ago. We know some people living with HIV struggle with taking daily oral pills, and Cabenuva may allow them to maintain viral suppression while significantly reducing dosing to as few as six times a year,” Baxter said in a statement.
Cabenuva is comprised of ViiV Healthcare’s cabotegravir extended-release injectable suspension and Janssen’s rilpivirine extended-release injectable suspension. The drug is a complete regimen for HIV-1 infection in adults who are virologically suppressed on a stable antiretroviral regimen with no history of treatment failure.
“In clinical trials, approximately nine out of every ten trial participants preferred long-acting cabotegravir and rilpivirine dosed every two months compared to daily oral cabotegravir and rilpivirine taken as the oral lead-in per trial protocol. This preference data highlights the meaningful impact long-acting regimens can have on the treatment experience for the HIV community,” Dr. Turner Overton, a professor in the Department of Medicine at the University of Alabama at Birmingham and ATLAS-2M primary investigator said in a statement.
HIV has taken the lives of an estimated 35 million people in the 41 years since it first emerged. It is currently estimated that about 1.1 million Americans live with HIV infection and approximately 38,000 Americans are diagnosed with the infection each year, which is down significantly from peak infections.
There has been a significant push from the U.S. government to eradicate the disease. During the previous presidential administration, the White House launched an initiative to reduce the number of new HIV infections in the United States by 75% by 2025. By 2030, the goal is to reduce infections by at least 90%, for an estimated 250,000 total HIV infections averted. The current administration has taken up the cause and pledged to meet the goal.
Multiple approaches are being made to combat HIV, including gene therapies by companies like American Gene Technologies and other treatments by Merck and Gilead Sciences.
