Does the political will exist to bring quality-assured and affordable drugs to low- and middle-income countries?

BACKGROUND: Increased coverage with antiretroviral therapy for people living with HIV in low- and middle-income countries has increased their life expectancy associated with non-HIV comorbidities and the need for quality-assured and affordable non-communicable diseases drugs . Funders are leaving many middle-income countries that will have to pay and provide quality-assured and affordable HIV and non-HIV drugs, including for non-communicable diseases. OBJECTIVE: To estimate costs for originator and generic antiretroviral therapy as the number of people living with HIV are projected to increase between 2016 and 2026, and discuss country, regional and global factors associated with increased access to generic drugs. METHODS: Based on estimates of annual demand and prices, annual cost estimates were produced for generic and originator antiretroviral drug prices in low- and middle-income countries and projected for 2016-2026. RESULTS: Drug costs varied between US$1.5 billion and US$4.8 billion for generic drugs and US$ 8.2 billion and US$16.5 billion for originator drugs between 2016 and 2026. DISCUSSION: The global HIV response increased access to affordable generic drugs in low- and middle-income countries. Cheaper active pharmaceutical ingredients and market competition were responsible for reduced drug costs. The development and implementation of regulatory changes at country, regional and global levels, covering intellectual property rights and public health, and flexibilities in patent laws enabled prices to be reduced. These changes have not yet been applied in many low- and middle-income countries for HIV, nor for other infectious and non-communicable diseases, that lack the profile and political attention of HIV. Licensing backed up with Trade-Related Aspects of Intellectual Property Rights safeguards should become the norm to provide quality-assured and affordable drugs within competitive generic markets. CONCLUSION: Does the political will exist among policymakers and other stakeholders to develop and implement these country, regional and global frameworks for non-HIV drugs as they did for antiretroviral drugs?

Projected Uptake of New Antiretroviral (ARV) Medicines in Adults in Low- and Middle-Income Countries: A Forecast Analysis 2015-2025.

With anti-retroviral treatment (ART) scale-up set to continue over the next few years it is of key importance that manufacturers and planners in low- and middle-income countries (LMICs) hardest hit by the HIV/AIDS pandemic are able to anticipate and respond to future changes to treatment regimens, generics pipeline and demand, in order to secure continued access to all ARV medicines required. We did a forecast analysis, using secondary WHO and UNAIDS data sources, to estimate the number of people living with HIV (PLHIV) and the market share and demand for a range of new and existing ARV drugs in LMICs up to 2025. UNAIDS estimates 24.7 million person-years of ART in 2020 and 28.5 million person-years of ART in 2025 (24.3 million on first-line treatment, 3.5 million on second-line treatment, and 0.6 million on third-line treatment). Our analysis showed that TAF and DTG will be major players in the ART regimen by 2025, with 8 million and 15 million patients using these ARVs respectively. However, as safety and efficacy of dolutegravir (DTG) and tenofovir alafenamide (TAF) during pregnancy and among TB/HIV co-infected patients using rifampicin is still under debate, and ART scale-up is predicted to increase considerably, there also remains a clear need for continuous supplies of existing ARVs including TDF and EFV, which 16 million and 10 million patients-respectively-are predicted to be using in 2025. It will be important to ensure that the existing capacities of generics manufacturers, which are geared towards ARVs of higher doses (such as TDF 300mg and EFV 600mg), will not be adversely impacted due to the introduction of lower dose ARVs such as TAF 25mg and DTG 50mg. With increased access to viral load testing, more patients would be using protease inhibitors containing regimens in second-line, with 1 million patients on LPV/r and 2.3 million on ATV/r by 2025. However, it will remain important to continue monitoring the evolution of ARV market in LMICs to guarantee the availability of these medicines.

Ensuring quality: a key consideration in scaling-up HIV-related point-of-care testing programs.

OBJECTIVE: The objective of the WHO/US President's Emergency Plan for AIDS Relief consultation was to discuss innovative strategies, offer guidance, and develop a comprehensive policy framework for implementing quality-assured HIV-related point-of-care testing (POCT). METHODS: The consultation was attended by representatives from international agencies (WHO, UNICEF, UNITAID, Clinton Health Access Initiative), United States Agency for International Development, Centers for Disease Control and Prevention/President's Emergency Plan for AIDS Relief Cooperative Agreement Partners, and experts from more than 25 countries, including policy makers, clinicians, laboratory experts, and program implementers. MAIN OUTCOMES: There was strong consensus among all participants that ensuring access to quality of POCT represents one of the key challenges for the success of HIV prevention, treatment, and care programs. The following four strategies were recommended: implement a newly proposed concept of a sustainable quality assurance cycle that includes careful planning; definition of goals and targets; timely implementation; continuous monitoring; improvements and adjustments, where necessary; and a detailed evaluation; the importance of supporting a cadre of workers [e.g. volunteer quality corps (Q-Corps)] with the role to ensure that the quality assurance cycle is followed and sustained; implementation of the new strategy should be seen as a step-wise process, supported by development of appropriate policies and tools; and joint partnership under the leadership of the ministries of health to ensure sustainability of implementing novel approaches. CONCLUSION: The outcomes of this consultation have been well received by program implementers in the field. The recommendations also laid the groundwork for developing key policy and quality documents for the implementation of HIV-related POCT.

Prices paid for adult and paediatric antiretroviral treatment by low- and middle-income countries in 2012: high, low or just right?

A viable market for antiretroviral drugs in low- and middle-income countries is key to the continued scale-up of antiretroviral treatment. We describe the price paid by low- and middle-income countries for 10 first- and 7 second-line adult and paediatric treatment regimens from 2003 to 2012, and compare the price of their finished formulations with the price of their active pharmaceutical ingredients in 2005, 2007, 2010 and 2012. Between 2003 and 2012 the median price of adult first-line treatment regimens per treatment-year decreased from USD499 to USD122, and that of second-line regimens from USD2,934 to USD497. In 2005 adult formulations were sold for a price 170% higher than the cost of their active pharmaceutical ingredients. This margin had decreased to 28% in 2012. Between 2004 and 2013, the price of paediatric treatment per treatment-year decreased from USD585 to USD147 for first-line and from USD763 to USD288 for second-line treatment. In 2005, paediatric treatment regimens were sold at a price 231% higher than the cost of their active pharmaceutical ingredients. This margin remained high and was 195% in 2012. The prices paid for antiretroviral drugs by low- and middle-income countries decreased between 2003 and 2012. Although the margins on their sale decreased, there is likely still space for price reduction, especially for the more recent World Health Organization recommended adult first-line regimens and for paediatric treatment.

Adoption of national recommendations related to use of antiretroviral therapy before and shortly following the launch of the 2013 WHO consolidated guidelines.

OBJECTIVE: To determine the status of key national policies on the use of antiretroviral therapy (ART) at the time of the launch of the 2013 WHO consolidated guidelines as well as to track early progress towards adoption of these recommendations following dissemination. DESIGN: Descriptive analysis of global data on baseline ART policies as of June 2013 and early intentions to adopt the 2013 WHO for use of antiretroviral drugs guidelines as of November 2013. METHODS: Compilation of existing global reports on key HIV policies, review of national guidelines, data collection through annual drug procurement surveys and through guidelines dissemination meetings in each of the six WHO regions. RESULTS: Data were available from 124 low- and middle-income countries, including 97% of the 57 high-priority countries that have been identified by WHO and the Joint United Nations Program on HIV/AIDS (UNAIDS). At baseline, only one country reported recommending antiretroviral therapy (ART) at a CD4 T-cell count 250 cells/µl or less for adults and adolescents in 2013, whereas nine countries already recommended using CD4 T-cell count 500 cells/µl or less. Recommendations for ART initiation regardless of CD4 T-cell count for HIV-infected patients with tuberculosis (86%), hepatitis B (75%), all HIV-infected women who were pregnant or breastfeeding (option B+: 40%) or HIV-infected persons in a serodiscordant relationship (26%) had been nationally adopted as of June 2013. Eight of 67 countries (12%) already recommended treating all children less than 5 years of age. The triple antiretroviral combination of tenofovir + lamivudine (or emtricitabine) + efavirenz was recommended as the preferred first-line option for adults and adolescents more frequently (51%) than for pregnant women (38%), or for both adults/adolescents and pregnant women (28%; P < 0.05). Fewer than half (37%) of all countries reported recommending lopinavir/ritonavir for all HIV-infected children less than 3 years of age; 54% of countries reported recommending routine viral load monitoring, whereas only 41% recommended nurse-initiated ART. CONCLUSIONS: A number of key WHO policy recommendations on antiretroviral drug use were adopted rapidly by countries in advance of or shortly following the launch of the 2013 guidelines. Efforts are needed to support and track ongoing policy adoption and ensure that it is accompanied by the scale-up of evidence-based interventions.

The WHO/PEPFAR collaboration to prepare an operations manual for HIV prevention, care, and treatment at primary health centers in high-prevalence, resource-constrained settings: defining laboratory services.

The expansion of HIV/AIDS care and treatment in resource-constrained countries, especially in sub-Saharan Africa, has generally developed in a top-down manner. Further expansion will involve primary health centers where human and other resources are limited. This article describes the World Health Organization/President's Emergency Plan for AIDS Relief collaboration formed to help scale up HIV services in primary health centers in high-prevalence, resource-constrained settings. It reviews the contents of the Operations Manual developed, with emphasis on the Laboratory Services chapter, which discusses essential laboratory services, both at the center and the district hospital level, laboratory safety, laboratory testing, specimen transport, how to set up a laboratory, human resources, equipment maintenance, training materials, and references. The chapter provides specific information on essential tests and generic job aids for them. It also includes annexes containing a list of laboratory supplies for the health center and sample forms.
