Regulatory Pathway for Licensing Biotherapeutics in Mexico

Dynamics of biosimilar uptake in emerging markets

INTRODUCTION

Globally, biosimilars are expected to play a key role in lowering healthcare costs and providing increased patient access to biological therapies. Given this, and in line with the European Union and World Health Organization, many emerging nations have adapted and established biosimilar regulatory guidelines. Emerging nations present a lucrative market for biosimilar development and commercialization, yet they also pose unique challenges. A thorough understanding of the unique attributes of emerging markets in relation to biosimilars is needed to promote their successful uptake in low- and middle-income countries.

AREAS COVERED

This article highlights the opportunities and challenges that emerging markets represent in terms of biosimilar uptake. A comprehensive analysis of biosimilar uptake in European countries, where biosimilars have gained significant market share, was carried out to identify policies that can enhance market penetration in emerging nations.

EXPERT OPINION

Implementation of pricing and procurement policies, as well as provider and patient confidence in biosimilar efficacy, are key factors in their uptake. Due to the high cost of biosimilar development, incentivizing domestic companies with the biosimilar manufacturing capability to produce these drugs will be helpful in ensuring a sustainable biosimilar market and a steady supply chain.

Biosimilar development and review process in the BRICS-TM countries: proposal for a standardized model to improve regulatory performance

OBJECTIVES

The current study is aimed at proposing a standardized regulatory model for biosimilar development and approval for adoption by BRICS-TM agencies, based on evaluation of regulatory guidelines and potential solutions to challenges.

METHODS

An established validated questionnaire was used and the recommendations were collated. Propositions deemed critical for improving the regulatory pathway for biosimilar development were synthesized to design a new regulatory model.

RESULTS

The key areas for improvement in BRICS-TM countries were: effective implementation of a step-wise approach; adoption of science-based regulatory evaluation for clinical efficacy studies and acceptance of analytical comparability studies in lieu of confirmatory clinical trials; a streamlined biosimilar development program for RBP sourcing; regulatory reliance for joint or shared review of the applications; and enhanced transparency and communication between the regulatory agencies and biosimilar developers. Based on these identified critical aspects, a simplified and standard regulatory model was developed to enable standardization of biosimilar guidelines across BRICS-TM countries for a common development program.

CONCLUSIONS

Effective implementation of the proposed standardized model for biosimilar development and approval processes across the BRICS-TM agencies will eliminate unwarranted studies, reduce the development costs and enhance process efficiency thereby expediting patients' access to new affordable biosimilar medicines.

Regulatory considerations in biosimilars: Latin America region

Development of biotherapeutic products has experienced steady growth over the past three decades. Expiration of patents on many biotherapeutics such as insulin, human growth hormone, and erythropoietin has opened the door for the development of biosimilars. The high cost of biotherapeutics has limited their accessibility, particularly in developing countries. Biosimilars offer the much- needed affordability and hence improved accessibility. Global agencies such as the World Health Organization are engaged in developing a prequalification program in order to help countries that do not have strong regulatory systems. This article summarizes the prospects of biosimilars in the Latin American market. Legal framework in various countries is also discussed.

Regulatory and strategic considerations for addressing immunogenicity and related responses in biopharmaceutical development programs

The last three decades have seen the biotherapeutic drug market evolve from promising concept to market dominance in a range of clinical indications. This growth has been spurred by the success of established drug classes like monoclonal antibodies, but also by the introduction of biosimilars, and more recently, multiple novel cell and gene therapies. Biotherapeutic drug development presents many unique challenges, but unintended immune responses are among the most common reasons for program attrition. Anti-drug antibodies can impact the safety and efficacy of drug products, and related immune responses, like the cytokine release syndrome that occurred in the infamous TGN-1412 clinical trial, can be challenging to predict with nonclinical models. For this reason, it is important that development programs proceed with a scientifically grounded and measured approach to these responses. This process begins at the discovery stage with the application of “quality by design,” continues into the clinic with the development of quality assays and management strategies, and culminates in the effective presentation of this information in regulatory documents. This review provides an overview of some of the key strategic and regulatory considerations for biotherapeutics as they pertain to immunogenicity and related responses.
