Increasing research and development funding for novel monoclonal antibodies will favor the market during the forecast period. For instance, according to an article published by BioProcess International in August 2022, monoclonal antibodies dominate the market with around a 50% share of the total commercialized biopharmaceutical products. This is expected to positively impact the global market.

Due to the unprecedented occurrence of the coronavirus pandemic, the healthcare industry underwent a major setback at the initial stage of the supply chain. The key players in the monoclonal antibodies therapeutics market experienced declining product sales growth. Amid the pandemic, the top-selling drug in the market, Humira, witnessed a positive growth of 4% as compared to the year 2019. However, some drugs such as Roche’s Herceptin, Avastin, and J&J’s Remicade observed a decline in revenues owing to the lower demand compared to the year 2019.

In a different scenario, the COVID-19 pandemic has boosted the R&D sector of companies to launch mAb-based COVID-19 treatments in the market. For instance, in November 2020, the U.S FDA granted emergency use authorization (EUA) to Regeneron Pharmaceuticals' monoclonal antibodies, casirivimab and imdevimab, to treat COVID-19. Therefore, such innovations impacted the global market sales during the forecast period. Furthermore, the continued launch of innovative monoclonal antibody therapies is anticipated to contribute to the market growth during the forecast period of 2024-2032.

Monoclonal Antibody Therapy Market Trends

Strategic Research Collaborations Will Open New Growth Opportunities

With the growing focus of operating entities toward developing mAb therapies for different indications, various strategic initiatives have been undertaken by these players. Along with this, increasing R&D investments in this sector have boosted these collaborations in the past few years, which in turn is becoming a significant market trend.

Monoclonal Antibody Therapy Market Growth Factors

Significant Investment in Development of Novel Therapeutics to Boost Growth

Monoclonal antibody therapy is a fast emerging extraordinary tool as a treatment option for chronic diseases, especially cancer. Preference towards these drugs is gradually rising, resulting in blockbuster sales of few products such as Herceptin and Humira, among others. This, in turn, has encouraged major pharmaceutical companies for huge research investments in the field of monoclonal antibodies. Along with the operating players, various government agencies such as the U.S. Department of Human Health Services (HHS) are also providing funds for the development of innovative mAb products. For instance, in August 2023, HHS awarded a funding of more than USD 1.4 billion for the Project NextGen. This project includes the development of monoclonal antibodies along with other therapies.

Apart from this, green signals from the regulatory authorities for the entry of biosimilars of existing products are further fostering the global market value.

Rising Prevalence of Chronic Diseases to Favor Market Growth

The increasing prevalence of chronic diseases such as cancer is one of the major factors augmenting the growth of the global market. Chronic diseases pose a major burden across the globe which is propelling the governments of various countries to put efforts in reducing the cost burden pertaining to their spread. According to the Centers for Disease Control and Prevention, 6 in every ten adults in the U.S. are suffering from a chronic disease, leading to an annual healthcare cost of USD 3.5 trillion. Furthermore, unmet patient needs and improving health reimbursement policies for therapeutic monoclonal antibodies used as a treatment option for chronic diseases are projected to fuel the monoclonal antibody therapy market growth.

RESTRAINING FACTORS

Stringent Regulatory Policies for Approval Process to Hamper Market Growth

Despite promising results for monoclonal antibodies in the treatment of various diseases, the long and strict regulations for approval and launch will be a major hindrance to the monoclonal antibodies therapy revenue. Many clinical studies are withdrawn mainly due to failure to meet the stringent regulations and end results framed by the regulatory authorities. The manufacturing process of all mAb products must adhere to the stringent regulatory guidelines to ensure the high quality of the final product. The filling of the final drug product must fulfill the requirements related to integrity, sterility, operational safety, and others. In addition to this, potential side effects of these drugs are other factors restricting the monoclonal antibody therapy market growth.

Monoclonal Antibody Therapy Market Segmentation Analysis

By Type Analysis

Human Monoclonal Antibody Segment to Dominate Market Owing to High Humira Sales

On the basis of type, the global market is segmented into human mAb, humanized mAb, chimeric mAb, and murine mAb.

The human mAb segment accounted for the dominating position with a share of 42.40% in 2026. This can be attributed to the higher sales and demand for Humira. Moreover, the entry of Adalimumab biosimilars is expected to augment the segment during 2026-2034. For example, in February 2024, dalimumab biosimilar (AVT02; Simlandi) was launched by Alvotech.

The humanized monoclonal antibody segment is poised to surge owing to the increased number of humanized mAb therapies and rising research funding by pharmaceutical companies. Genentech, a company of Roche, is conducting research on Obinutuzumab, a humanized anti-CD20 monoclonal antibody for the treatment of end-stage renal disease. This is likely to render remarkable growth to the humanized mAb segment. Technological advancement to develop a molecular-level understanding of diseases, rising aging population, and expanding applications of monoclonal antibodies are factors contributing to the expansion of the chimeric monoclonal antibody and murine monoclonal antibody segments.
