GLP-1 Patents and Africa: The COVID-19 Lessons We Still Have Not Learned

The emergence of GLP-1 receptor (搜索)搜索该靶点 agonists has fundamentally reshaped the treatment landscape for type 2 diabetes (搜索)搜索该疾病 and obesity (搜索)搜索该疾病, yet the same intellectual property tensions that defined the COVID-19 pandemic are now resurfacing across the African continent. As Sofia Araújo of Inventa argues, the question is no longer about innovation—it is about access.

Semaglutide查看药品详情, marketed under the Ozempic and Wegovy brands by Novo Nordisk查看公司主页, and tirzepatide查看药品详情, commercialised by Eli Lilly查看公司主页, have delivered clinical outcomes that were difficult to achieve with previous therapies. However, protection extends far beyond the active pharmaceutical ingredient itself. The relevant patent landscape includes claims relating to formulations, methods of administration, dosage regimes and specific therapeutic indications—a strategy commonly described as evergreening that continues to fuel debate over whether secondary patents strike an appropriate balance between rewarding innovation and delaying generic competition.

In many jurisdictions where semaglutide查看药品详情 is available, the monthly cost of treatment remains well beyond the reach of most African health systems and, inevitably, most patients.

Africa's silent diabetes crisis

According to the International Diabetes Federation, Sub-Saharan Africa is expected to experience the highest proportional increase in diabetes cases worldwide by 2045. Rapid urbanisation, changing dietary habits and increasingly sedentary lifestyles are transforming what was once an underdiagnosed condition into one of the continent's most pressing public health concerns.

Unlike infectious diseases, diabetes rarely generates images that mobilise international attention. Instead, it progresses quietly, contributing to cardiovascular diseases, kidney failure, amputations and mounting pressure on already fragile healthcare systems. Against this background, access to innovative therapies should not be viewed merely as a question of improving quality of life. As Araújo notes, "It is equally a matter of strengthening public health systems and preventing complications that, in the medium and long term, impose far greater human and economic costs."

Compulsory licensing: A legal tool that remains on the shelf

International intellectual property law is not indifferent to public health concerns. Article 31 of the TRIPS Agreement allows WTO Members to authorise the use of patented inventions without the consent of the patent holder, provided that certain conditions are met and adequate remuneration is paid. The Doha Declaration on the TRIPS Agreement and Public Health reinforced this principle by confirming that Members are free to determine what constitutes a national emergency or other circumstances of extreme urgency.

The 2003 WTO General Council Decision, later incorporated into Article 31bis of TRIPS, further expanded these flexibilities by enabling countries with insufficient pharmaceutical manufacturing capacity to import generic medicines produced under a compulsory license. On paper, therefore, the legal framework appears robust.

In practice, however, compulsory licensing has remained the exception rather than the rule across much of Africa. Political pressure, trade considerations and concerns about foreign investment have often discouraged governments from relying on these mechanisms, even where significant public health interests are at stake.

More fundamentally, compulsory licensing is only part of the answer. The manufacture of peptide-based medicines such as semaglutide查看药品详情 and tirzepatide查看药品详情 requires sophisticated technology, specialised expertise and complex supply chains that many African countries are still developing. Without technology transfer and increased regional manufacturing capacity, the practical impact of compulsory licenses remains limited.

The COVID-19 lesson that risks being forgotten

The COVID-19 pandemic was widely expected to reshape the relationship between intellectual property and public health. In October 2020, South Africa and India proposed a temporary waiver of certain TRIPS obligations covering vaccines, diagnostics and treatments, arguing that existing intellectual property rules could become a barrier to equitable access during a global health emergency.

The negotiations that followed demonstrated just how difficult it remains to reconcile commercial interests with public health priorities. After almost two years of discussions, WTO Members agreed on a compromise that applied only to vaccines and was accompanied by operational limitations that significantly reduced its practical effect.

The debate surrounding GLP-1 medicines presents a remarkably similar challenge, but in a less visible context. Diabetes and obesity (搜索)搜索该疾病 do not overwhelm hospitals overnight, nor do they generate the political urgency associated with a pandemic. Their impact is gradual, cumulative and, for that very reason, easier to postpone. The absence of an immediate emergency creates the illusion that there is still time to act, even as the number of patients requiring long-term treatment continues to grow.

A comprehensive strategy for the continent

The conversation should not be reduced to whether compulsory licenses ought to be granted. A more comprehensive strategy is required.

From a legal perspective, countries with greater institutional capacity—such as South Africa, Egypt, Morocco and Nigeria—could play a leading role in testing and implementing the TRIPS flexibilities available for essential medicines, creating practical precedents for the rest of the continent.

At the regional level, the African Continental Free Trade Area (AfCFTA) provides an opportunity to strengthen regulatory cooperation and coordinate procurement strategies. As Araújo states, this could ultimately increase "Africa's collective bargaining power."

At the same time, policymakers should continue to scrutinise the growing use of secondary pharmaceutical patents and consider whether current patent practices strike the appropriate balance between rewarding innovation and facilitating timely generic entry.

Yet perhaps the most important lesson lies elsewhere. Without sustained investment in local pharmaceutical manufacturing, research capacity and technology transfer, access debates will continue to focus on legal rights rather than practical solutions. The post-COVID initiatives aimed at expanding vaccine production across Africa demonstrate that industrial capacity can be developed when political will and international cooperation converge. Similar efforts may now be required for non-communicable diseases.

The discussion surrounding GLP-1 medicines illustrates that the real legacy of COVID-19 is not simply the reaffirmation of the TRIPS flexibilities. Rather, it is the recognition that legal mechanisms alone cannot guarantee access to essential medicines. Compulsory licensing remains an important instrument, but its effectiveness depends on manufacturing capacity, technology transfer, regulatory coordination and political commitment. Patent law is only one part of a much broader equation.

The growing burden of diabetes across Africa provides an opportunity to rethink how intellectual property, public health and industrial policy interact before the continent faces another access crisis. The legal tools already exist. The more difficult question is whether governments are prepared to use them and whether the international community is willing to support a model of pharmaceutical innovation that rewards research while recognising that access to essential medicines is, ultimately, a matter of public interest.
