Dynamics of biosimilar uptake in emerging markets

Evaluating biosimilars: safety, efficacy, and regulatory considerations in clinical studies

Biosimilars are a rapidly growing area of clinical research, yet they encounter significant challenges, especially in emerging markets where regulatory and clinical hurdles differ markedly from those in established regions like Europe and the US. This commentary addresses these unique challenges and offers new perspectives on the global adoption of biosimilars. It emphasizes the crucial role of real world evidence in supporting biosimilar approvals, an aspect often underrepresented in current literature. The commentary also provides a comparative analysis of the regulatory frameworks in China and Europe, highlighting how these differences shape biosimilar development and market approval processes. By focusing on the issues of indication extrapolation and immunogenicity, this commentary highlights the necessity of continuous real-world data collection to ensure the safety and efficacy of biosimilars across multiple indications. Our analysis enhances the understanding of biosimilar research and supports their broader adoption as safe, effective, and accessible healthcare solutions globally.

Biosimilars in the Era of Artificial Intelligence-International Regulations and the Use in Oncological Treatments

This research is based on three fundamental aspects of successful biosimilar development in the challenging biopharmaceutical market. First, biosimilar regulations in eight selected countries: Japan, South Korea, the United States, Canada, Brazil, Argentina, Australia, and South Africa, represent the four continents. The regulatory aspects of the countries studied are analyzed, highlighting the challenges facing biosimilars, including their complex approval processes and the need for standardized regulatory guidelines. There is an inconsistency depending on whether the biosimilar is used in a developed or developing country. In the countries observed, biosimilars are considered excellent alternatives to patent-protected biological products for the treatment of chronic diseases. In the second aspect addressed, various analytical AI modeling methods (such as machine learning tools, reinforcement learning, supervised, unsupervised, and deep learning tools) were analyzed to observe patterns that lead to the prevalence of biosimilars used in cancer to model the behaviors of the most prominent active compounds with spectroscopy. Finally, an analysis of the use of active compounds of biosimilars used in cancer and approved by the FDA and EMA was proposed.

Global outlook on affordability of biotherapeutic drugs

Although biotherapeutic drugs have the potential of transforming the management of many life-threatening diseases, their affordability and accessibility remain an issue. This study offers an overview of the global affordability of biotherapeutic products. For this, prices for 10 representative biotherapeutic products were examined in 40 countries, including high-income countries (HICs), upper middle-income countries (UMICs), lower middle-income countries (LMICs), and low-income countries (LICs). The affordability of these biotherapeutics was calculated based on the World Health Organization/Health Action International (WHO/HAI) method. As expected, affordability was found to be better in HICs, followed by UMICs, LMICs, and finally, LICs. Furthermore, based on the trend of per capita income, we predict that in UMICs and LMICs, the affordability of high molecular weight biologics will worsen by 1.5× and 2× by 2030, respectively, and further by 4× and 6× by 2040. On the other hand, affordability will stay nearly the same for people living in HICs in the coming decades. Our analysis suggests that it is imperative that measures be taken to make this class of products more affordable and accessible. Governments can contribute by creating conducive policies. Global institutions like the WHO can play a significant role as well. Finally, manufacturers need to invest in and implement manufacturing innovations.

Does the first generic exclusivity system provide an economic incentive for early generic entrance under the patent linkage system?

Introduction

A period of exclusivity for the first generics, as part of the patent linkage system, was established in South Korea to provide an economic incentive for early generic entry. This study describes the dynamics of generic penetration and assesses the first mover market share advantages under the patent linkage system.

Methods

Pairs of originators and their corresponding generics granted the first generic exclusivity from 2015 to 2020 were identified. We categorized generics into first movers and latecomers, described the penetration curves of generics, and estimated the saturated market share of generics, first movers, and latecomers. Volume-based monthly prescriptions were used to describe the generics' penetration curves. A logistic growth model was adopted to estimate the saturated market shares of generics.

Results

We identified 28 pairs of originators and generics, presented penetration curves, and estimated generics market shares. The saturated market share of generics was 30%, and the time to saturation was approximately 33 months. The shapes of penetration varied by nationality, route, and number of generics. The existence of latecomers was associated with the decreased penetration speed over time and decreased market share of generics. However, the first mover market share advantages or latecomers' disadvantages were consistently observed.

Conclusion

The generic uptake in South Korea is delayed, limited, and context-dependent. However, first generics' market share advantage suggests that a period of exclusivity, as part of the patent linkage system, could provide an economic incentive for early generic entrance.

Continuous integrated manufacturing for biopharmaceuticals: A new paradigm or an empty promise?

Continuous integrated bioprocessing has elicited considerable interest from the biopharma industry for the many purported benefits it promises. Today many major biopharma manufacturers around the world are engaged in the development of continuous process platforms for their products. In spite of great potential, the path toward continuous integrated bioprocessing remains unclear for the biologics industry due to legacy infrastructure, process integration challenges, vague regulatory guidelines, and a diverging focus toward novel therapies. In this article, we present a review and perspective on this topic. We explore the status of the implementation of continuous integrated bioprocessing among biopharmaceutical manufacturers. We also present some of the key hurdles that manufacturers are likely to face during this implementation. Finally, we hypothesize that the real impact of continuous manufacturing is likely to come when the cost of manufacturing is a substantial portion of the cost of product development, such as in the case of biosimilar manufacturing and emerging economies.
