Escalating R&D investments
Increased research and development (R&D) spending is a major catalyst for growth in the small molecule innovator CDMO market. Pharmaceutical and biotechnology companies are making substantial investments in R&D in order to foster innovation and speed the drug discovery process. Broadly speaking, pharma giants spend between 14% and 30% of their revenues on R&D, highlighting the industrys reliance on R&D. As a point of reference, the European Federation of Pharmaceutical Industries and Associations (EFPIA) report that in 2022, total pharma spending on R&D in Europe was USD 44,500 million, up from USD 42,533 million in 2021.
Additionally, pharma investment in R&D in the U.S. continues to increase, reflecting the global expectation for drug innovation. This shift to increased investment in R&D will lead to greater dependency on CDMOs for specialized services, process development, validation, and regulatory assurance. Generally speaking, when biotechnology or pharmaceutical companies utilize CDMO competency, they are able to substantially lower costs, reduce risk, and accelerate the time-to-market for new small-molecule therapies that improve the quality of patient outcomes on a global scale.
Regulatory burden
The significant regulatory restraints and compliance requirements are one of the biggest constraints in the Small-Molecule Innovator CDMO market. Regulatory context, with entities like the FDA and EMA, marks clear guidelines for drug development through approval for manufacturing and quality control, translating into long timelines for approval, and expenses like time and financial capacity, that can be laborious outside of compliance. The cost of non-compliance can be proportional to the edge case that regulatory agencies choose to apply.
In addition to regulations evolving, for example, the EUs Annex 1, revised on sterile drug manufacturing, will require an investment in new infrastructure and technologies for CDMOs to act in compliance with baseline regulations. This compliance burden could be a significant cap on any potential growth in the small-molecule innovator CDMO market, while smaller CDMO innovators suffer as having capital equity restraints as well as operational implementation complications.
Chronic Disease Surge
The increasing incidence of chronic diseases has created a tremendous opportunity for the small molecule innovator CDMO market. For the purpose of this research, chronic diseases are diseases that last one year or longer and require continuous medical care. Chronic diseases are increasingly being identified globally. In 2022, cardiovascular diseases alone accounted for approximately 944,652 deaths in the United States, more than cancer and all other chronic respiratory diseases combined. Diabetes, cancer, and respiratory diseases are also trending upward, and projections indicate increased incidence rates through the year 2025.
The increased burden of chronic disease will result in increased need for innovative small-molecule drug therapies. Small Molecule Innovator CDMOs play an integral role in the development and manufacture of these drugs for pharmaceutical/biotech companies. As chronic disease incidence increases, these CDMOs are in a strong position to grow their contributions to the healthcare sector, thereby supporting the enablement of new treatments to meet healthcare needs on a global scale.
In 2024, the small molecule API segment held the largest small molecule innovator CDMO market share. This dominance is attributed to both the demand for innovative small-molecule therapies and the ongoing approvals of new APIs by regulatory agencies, such as the U.S. FDA, which is expected to continue this trend. For example, in 2024, the FDA granted approvals for 50 new drugs, which included 31 small molecules, 19 biologics, and 24 first-in-class drugs, which is also equal to 50 new molecular entities (NMEs). Approvals like this are likely to expand and continue in the upcoming years.
Additionally, the small-molecule drug product segment is anticipated to grow at a remarkable CAGR between 2025 and 2034 as it continues to adapt with innovations in drug delivery and more regulators standards to improve quality and efficacy. However, not every company has developed the capability to manufacture these products commercially at scale, which makes it tough for them to comply with their regulations. There are many companies that have been able to mitigate this through an understanding with CDMO companies, which have experience in manufacturing, state-of-the-art GMP facilities, regulatory expertise, and reliable quality systems. These CDMO companies can help many organizations create seamless compliance and reduce compliance risk in this segment.
The clinical segment captured the biggest small molecule innovator CDMO market share in 2024, due to the significant number of small-molecule drugs in the pipeline and increasing R&D expenditure. The global pharmaceutical R&D expenditure in 2024 exceeded USD 276 billion, demonstrating the industrys continued focus on innovation and drug development. The sustained increase in R&D expenditure is expected to spark increased development of novel therapies and solidify the clinical-stage segment. The rise in clinical-stage drug pipeline development is also attributed to increasing collaboration among biotech companies, pharmaceutical companies, and research institutions.
The commercial segment is expected to grow at a notable CAGR over the projected period, due to the growing trend of small and mid-size pharmaceutical companies outsourcing their operations. Companies with substantial numbers of commercially available small-molecule innovator drugs are increasingly partnering with specialized CDMOs and outsourcing their manufacturing needs in order to focus on their core competencies. Utilizing specialized CDMOs also allows for compliance with a complex regulatory environment and increasing efficiencies in their operations, enabling pharmaceutical companies to reallocate resources toward drug development and marketing.
The oncology segment captured the biggest small molecule innovator CDMO market share in 2024 because of the increasing global cancer burden, which reached over 20 million new cases and 9.7 million deaths in 2022. The burden of cancer is expected to increase by 77% by 2050. This increase will create demand for novel anti-cancer treatments and CDMO services in this area. The increasing development of HPAPIs will further bolster the leadership of this segment, along with the rising adoption of targeted therapies.
The infectious disease segment is projected to expand at a notable CAGR over the projected period, stemming from the immediate need for new antibiotics, antiviral drugs, and preparedness for pandemics. Because of increased antimicrobial resistance and new infectious disease emergence, R&D in this area has gained rapid momentum, resulting in pharmaceutical companies partnering with CDMOs for efficient API development. The increase in a required global move to shore up healthcare capability and preparedness for future outbreaks has, in addition to the above, created a higher level of investment and rate of growth in the infectious diseases category.
The pharmaceutical captured the biggest small molecule innovator CDMO market share in 2024 because of the ongoing reliance on small-molecule medications in the treatment of chronic and acute diseases. Major pharmaceutical manufacturers often outsource API production to Contract Development and Manufacturing Organizations (CDMOs) for cost-effectiveness, regulatory approaches, and leverage specialization. Furthermore, the established supply chains, quality practices, and the growing demand for generic and branded small-molecule drugs solidify the segments position.
Meanwhile, the biotechnology segment is expected to grow at a notable CAGR over the projected period due to innovation in therapeutics being driven by new investments in research and development (R&D) and the increase in the number of biotech startups focused on therapeutics. As the expansion of targeted therapies, personalized medicine, and biologics continues to grow, the need for specialized CDMO partnerships for these products has followed suit. In addition to biologics, advancements in synthetic biology and complex molecule synthesis are driving the growth of this segment, as biotech companies are looking for CDMOs with niche expertise and high-value API manufacturing for the development of unprecedented treatments.
