Equitable Access to Long-Acting HIV Treatment
For people living with HIV (PLWH), adherence to antiretroviral therapy (ART) is crucial. Achieving and maintaining viral suppression, the primary goal of HIV treatment, depends on taking medication as prescribed. Yet, consistent adherence can be challenging due to busy schedules, pill fatigue, stigma, and side effects. Suboptimal adherence has serious consequences, including increased viral load rebound, drug resistance, and disease progression. It also hinders public health efforts to control the HIV epidemic. Long-acting injectable (LAIs) antiretroviral therapies offer a promising alternative by providing sustained viral suppression with less frequent dosing. However, a significant barrier remains: equitable access. Some State AIDS Drug Assistance Programs (ADAPs), designed to support low-income PLWH, do not adequately cover these medications due to cost concerns .
This limited coverage is a public health issue and a moral failing. State ADAPs must provide equitable access to the most effective HIV treatments available that meet the unique needs of the patient, regardless of cost. While the initial expense of LAIs may be high, their potential to improve adherence, viral suppression, and long-term health outcomes far outweighs the financial investment. It's time for ADAPs to prioritize the health of PLWH by ensuring access to LAIs and supporting efforts to end the HIV epidemic.
The Promise of LAIs
LAIs represent a major advancement in HIV treatment. Unlike daily oral ART, which requires daily ingestion and absorption, LAIs are administered as intramuscular injections, typically once a month or every two months. These injections provide a steady release of medication, ensuring consistent drug levels and effective viral suppression.
The benefits of LAIs are significant. The MOCHA study found that adolescents overwhelmingly favored LAIs due to the convenience of less frequent dosing . This reduces the daily burden of remembering to take pills, leading to improved adherence rates—a key factor for successful HIV treatment.
Improved adherence through LAIs also enhances long-term health outcomes and reduces the risk of HIV transmission. When the virus is undetectable, it cannot be sexually transmitted, a concept known as Undetectable = Untransmittable (U=U). By promoting optimal adherence and sustained viral suppression, LAIs become a powerful tool in the fight against the HIV epidemic.
Evidence of Effectiveness
The effectiveness of LAIs is supported by considerable scientific evidence. The MOCHA study found that after 24 weeks of treatment with long-acting cabotegravir/rilpivirine, none of the nearly 150 participants experienced virological failure. This highlights the potential of LAIs to achieve durable viral suppression, especially among younger populations who often struggle with adherence to daily oral regimens.
The LATITUDE study, focusing on PLWH with a history of suboptimal adherence to oral ART, found that long-acting injectable therapy was superior in suppressing HIV replication compared to daily oral medication . The compelling results led the National Institutes of Health Data and Safety Monitoring Board to recommend offering the long-acting medication to all eligible participants.
These studies, along with a growing body of research, show that LAIs are effective in achieving viral suppression and are particularly beneficial for those who struggle with adherence to traditional oral ART. This makes LAIs a critical tool for addressing disparities in HIV treatment outcomes and advancing health equity among PLWH.
Impact on the HIV Epidemic
The effectiveness of LAIs in maintaining viral suppression has significant implications for public health, especially the Ending the HIV Epidemic (EHE) initiative, which aims to reduce new HIV infections in the United States by 90% by 2030. Achieving this goal requires expanding access to effective prevention and treatment options.
LAIs support this effort by fostering optimal adherence and sustained viral suppression. By ensuring that PLWH have access to medications that effectively suppress the virus, we improve health outcomes and reduce the likelihood of transmission, moving closer to the EHE goal.
LAIs also align with the 95-95-95 targets set by UNAIDS, adopted by the EHE initiative, which aim to ensure that 95% of PLWH know their status, 95% of those diagnosed receive sustained ART, and 95% of those on treatment achieve viral suppression. By improving adherence and facilitating viral suppression, LAIs contribute to achieving these targets and reducing new cases.
The International Association of Providers of AIDS Care (IAPAC) emphasized the importance of LAI access for supporting the goals of the Fast-Track Cities initiative . This initiative aims to accelerate progress towards ending the HIV epidemic at the local level. IAPAC argues that providing PLWH with access to effective ART options like LAIs is essential for achieving these ambitious targets.
The Cost Conundrum
The benefits of LAIs are often overshadowed by concerns about cost. Critics, including some state ADAP administrators, point to the high upfront price of these medications compared to generic oral ART options. A 2023 article on AIDSmap highlighted that the price of long-acting cabotegravir would need to drop considerably to be cost-effective compared to daily oral PrEP . This concern about cost is echoed in discussions surrounding LAIs for treatment, with some stakeholders questioning whether the potential benefits justify the higher price tag.
A recent article in TheBody revealed that the annual cost of Cabenuva, a commonly prescribed LAI, is approximately $40,000. This figure highlights the need for careful consideration of drug pricing within ADAP formularies. For comparison, the annual retail cost of the popular oral ART treatment Biktarvy is just over $50,000. However, as of January 2023, only 78% of state ADAPs covered Cabenuva.
This gap in coverage disproportionately affects the most vulnerable PLWH. In states without Cabenuva coverage, nearly two-thirds of ADAP clients live at or below the federal poverty level, compared to 43% in states with coverage. Additionally, ADAP clients in states lacking Cabenuva coverage are more likely to be Black or Hispanic .
While cost is a valid concern, focusing solely on upfront expenses overlooks the potential for long-term savings. ADAPs can negotiate lower drug prices and must consider the broader economic and public health benefits of LAIs.
A Holistic Cost-Benefit Analysis
A comprehensive cost-benefit analysis must consider the long-term impact on healthcare expenditures and public health outcomes. A narrow focus on upfront costs ignores the potential of LAIs to generate significant savings over time.
The HIV+Hepatitis Policy Institute modeled the impact of long-acting PrEP on HIV case aversion and medical cost savings, concluding that improved adherence leads to better health outcomes and reduced transmission, ultimately saving costs for the healthcare system. They projected that increased uptake of long-acting PrEP would avert 139,296 person-years of HIV treatment over ten years, saving $4.25 billion .
Preventing new HIV infections through improved adherence not only saves on direct treatment costs but also reduces the need for costly interventions related to managing complications and comorbidities of advanced HIV. By minimizing the risk of transmission, LAIs contribute to a decrease in HIV prevalence, further reducing long-term healthcare costs and saving lives in the process.
Intangible Benefits
The benefits of LAIs extend beyond economics. These medications significantly improve the quality of life and overall well-being of PLWH.
The MOCHA study highlighted that young people preferred LAIs due to reduced treatment anxiety and fatigue. They appreciated the increased privacy, as they no longer needed to take daily pills that might disclose their HIV status.
ADAP Advocacy emphasizes the importance of patient empowerment and choice in HIV care. LAIs provide PLWH with greater autonomy in managing their health, aligning treatment with their personal needs and lifestyles. This sense of control improves mental health, self-esteem, and quality of life.
By reducing the frequency of medication-related tasks, LAIs help minimize the stigma associated with HIV. Daily pill-taking can serve as a constant reminder of one's HIV status, triggering feelings of shame or fear of disclosure. LAIs, with less frequent dosing, allow PLWH to integrate their care more seamlessly into their lives, reducing the psychological burden.
These intangible benefits, while difficult to quantify economically, should weighed equally when making decisions that affect patient care and access. They highlight the profound impact of LAIs on the lives of PLWH, extending beyond viral suppression to encompass improved quality of life, reduced stigma, and increased autonomy.
Ethical Considerations
Equitable access to LAIs is an ethical imperative. State ADAPs, as safety-net programs for low-income PLWH, have a moral duty to provide access to the most effective HIV treatments, regardless of cost. Denying access based on price perpetuates health disparities and undermines equity.
IAPAC argues that access to innovative treatments like LAI-ART should not depend on socioeconomic status. Providing ADAP coverage for LAIs is crucial for equitable healthcare.
Restricting LAI access disproportionately impacts those already facing systemic barriers, including people of color, those with low income, and those in rural areas. These populations are more likely to have adherence challenges due to social, economic, and structural factors. Denying them access to LAIs further entrenches health inequities.
A commitment to health equity demands prioritizing the needs of the most vulnerable. Cost concerns, while valid, cannot justify denying essential healthcare to those who need it most. State ADAPs must ensure all PLWH can benefit from LAIs, regardless of financial circumstances.
Addressing Barriers and Implementing Solutions
Ensuring equitable access to LAIs requires a multi-faceted approach, addressing cost concerns and systemic barriers. Policy changes at federal and state levels are necessary for creating a more just healthcare system for PLWH.
Policy Recommendations for ADAPs
Mandate LAI Coverage: State legislatures should require ADAPs to cover all FDA-approved LAIs for HIV treatment. This would ensure all eligible PLWH have access to these medications.
Streamline Prior Authorization: ADAPs should streamline prior authorization processes for LAIs, minimizing delays and ensuring timely access to treatment. This could include standardized approval criteria, expedited review processes, and clear communication between providers and ADAP administrators.
Increase Funding Allocations: State and federal governments must prioritize increased funding for ADAPs, recognizing the growing demand for LAIs and their long-term cost savings potential.
Provider Education and Training
The ADAP Advocacy Association underscores the need for robust provider education and training on LAIs. They advocate for targeted education about providing LAIs within a modified clinic flow model.
Ongoing education initiatives should focus on:
LAI Pharmacology and Administration: Providers need a thorough understanding of LAIs, including dosing schedules, potential side effects, and proper administration techniques.
Patient Selection and Counseling: Training should equip providers to identify appropriate candidates for LAIs, considering personalized patient needs and potential adherence barriers. Effective counseling strategies are necessary for addressing concerns and ensuring informed decisions.
Addressing Provider Bias: Some providers may hold misconceptions about LAIs, such as concerns about patient acceptance or injection-related anxiety. Training programs should address these biases, providing evidence-based information and dispelling myths.
By investing in comprehensive provider education and training, we can empower healthcare professionals to embrace LAIs confidently, facilitating broader access and improved health outcomes for PLWH.
Patient Advocacy and Support
Community activism has been a hallmark of the U.S. HIV response, and PLWH should work with clinicians to advocate for state ADAPs to prioritize patient choice and treatment preferences.
PLWH and community organizations can play a powerful role by:
Sharing Their Stories: Personal narratives are powerful tools for raising awareness and influencing policy change. PLWH who have benefited from LAIs can highlight the positive impact, while those denied access can shed light on the challenges and the need for equitable coverage.
Engaging with ADAP Advisory Committees: Many state ADAPs have advisory committees of stakeholders, including PLWH. Participating in these committees provides an opportunity to voice concerns and advocate for policy changes.
Collaborating with Advocacy Organizations: Partnering with national and local organizations can amplify voices, provide resources, and facilitate collective action for policy changes.
Educating Their Peers: PLWH can educate peers about LAIs, dispelling myths and sharing information about the benefits and potential challenges. Peer-to-peer support can empower people to advocate for their health and make informed treatment decisions.
By raising voices, sharing experiences, and engaging in collective action, we can drive progress towards equitable LAI access, ensuring all can benefit from these transformative medications.
Conclusion
Long-acting injectable antiretroviral therapies (LAIs) represent a major advancement in HIV treatment, offering a powerful tool for improving adherence, achieving sustained viral suppression, and ending the HIV epidemic. While cost concerns are valid, a holistic cost-benefit analysis shows that the long-term benefits of LAIs far outweigh the initial investment.
The time for action is now. Contact your state legislators, ADAP representatives, and other stakeholders. Demand equitable LAI coverage and support policies that prioritize the health and well-being of all PLWH. Together, we can dismantle barriers to access and ensure no one is left behind in the fight to end the HIV epidemic.
