Cabenuva Approved for 2 Month Injections; Insurers Remain a Barrier to Access

In late January of 2021, ViiV Healthcare and Janssen Pharmseutical Companies announced the Food and Drug Administration’s (FDA) approval of the first extended-release injectable medication regimen for the treatment of HIV as a once-monthly administration, branded as Cabenuva. Eleven (11) months later, the FDA approved cabotegravir as an extended-release injectable suspension for the prevention of HIV as a once-every-two-month administration, branded as Apretude. Again, on February 1, 2022, the FDA expanded Cabenuva’s administration to be a once-every-two-month administration. Near overnight, people living with HIV-related medication therapy and prevention efforts went from a burdensome three-hundred sixty-five (365) pills to six (6) injections.

This kind of innovation has been long anticipated and while advocates and patients recognize not every patient will desire to switch to injectable medications and resistance profiles may require some people living with HIV to maintain their tablet regimens, injectables offer yet another tool in the tool box. The extended-release nature of injectables offer an opportunity to overcome “treatment fatigue”, reduce opportunities for missed doses and subsequent treatment resistance, and even address safety in storing medications at-home – especially for those people living with and at risk for acquiring HIV that may also be experiencing houselessness. This becomes even more of an astounding tool, in addressing disruptions in care when patients live in areas prone to natural disasters, as seen in Florida during Hurricane Michael when the state’s central pharmacy operations came to a halt, forcing the state to rely on a private-public partnership with CVS, and in Puerto Rico after Hurricane Maria, in which patients lost access to life-saving medications. The issue of natural disasters interrupting care is not new and will likely be something providers and patients need to have plans for as every indication exists climate change will produce more and more powerful hurricanes. Indeed, despite the lessons learned from Hurricane Katrina, I personally witnessed multiple calls across social media channels among people living with HIV seeking additional medication in order to manage loss of their anti-retrovirals in 2021, during Hurricane Ida. Despite the state of Louisiana and the department of Health and Human Services declaring a public health emergency and activating the Emergency Prescription Assistance Program for uninsured and underinsured patients, anecdotal reports found the program hard to manage for those who needed daily administration of medications.

Yet and still, despite these incredible advancements at our finger tips, both public and private insurance programs remain reticent to allow patient and provider choice to guide what therapies patients actually have access to. Indeed, one of the largest payers in both the public and private spaces is CVS Health, who, on December 16, 2021, published priorities in “weighing cost” versus clinical benefit while specifically naming cabotegravir as an active agent in Cabenuva and Apretude. The payer outlines tactics known as “utilization management” to include initially blocking coverage of new drugs, “strongly favor[ing] generic use”, and “select[ing a] preferred agent generating lowest net cost option in category”. Even some AIDS Drug Assistance Programs (ADAPs) are delaying adding the innovative therapy to their coverage formularies. All of which creates a system of care where people living with HIV are experiencing limitations on their access to effective therapies based on their income, rather than their need as determined by them, as patients, and their provider. Deny-first utilization management practices risk losing people to care by creating unnecessary and burdensome administrative process and delays.

When Cabenuva was first approved, advocates in the community and among public services stressed concern about getting patients to return for monthly shots and the logistics of administering the shots. The concern on costs to public programs also raised its head and has done so even more recently as a limited study concluded Apretude wasn’t “cost-effective”. However, in the time since these initial discussions, tens of millions of people have received their COVID-19 vaccines, which are situated a mere 3 weeks apart and variant development has left many experts expecting the need for annual boosters of the same. The logistics of administering shots have clearly been addressed. As for the “cost-effectiveness” study, the limitation the authors cite is one that’s patently…ridiculous: “Uncertain clinical and economic benefits of averting future transmissions.” We well know the clinical benefits of preventing transmissions means fewer HIV diagnoses, a goal outlined by the United States’ federal government in the Ending the HIV Epidemic initiative, and the economic realities of preventing new transmissions is as apparent in reducing the costs of care associated with stagnant or even rising transmission rates.

The truth is, long-acting anti-retroviral therapies are the next step in innovation at extending effective care to people at risk of acquiring and living with HIV. These advancements will come with a cost that is significantly outweighed by improvements in patient quality of life, retention in care, and reduction in new transmissions. If we aren’t careful in ensuring equitable access to these innovations, existing health disparities will only grow. Barriers to care originating from payer processes, from formulary inclusion to co-pay accumulator programs, should be well-documented by providers and advocates need to be forceful in seeking access to these innovations for all patients, regardless of income or economic status. Policymakers, lawmakers, and regulators need to move quickly to address these barriers. Innovation waits for no one and that which exists in the balance between these interests are people’s quality of life and their very lives.
