The recent JPMorgan Healthcare Conference held in San Francisco shed light on the growing market for antibody-drug conjugates (ADCs) within the biotech and pharmaceutical industry. ADCs are a group of cancer drugs that deliver targeted therapy to cancer cells while minimizing damage to healthy cells. The appeal of ADCs lies in their selectivity, as standard chemotherapy often affects both cancerous and healthy cells. This distinction has garnered significant interest from companies like Johnson & Johnson, Pfizer, and Merck, who see ADCs as key drivers for future growth in their businesses.
The factors responsible for the recent surge in ADCs will likely continue to drive the market forward. Increased confidence in ADC technology among companies and researchers, along with the potential for longer market exclusivity and the emergence of attractive ADCs from Asian drugmakers, are all contributing to the growing interest in these drugs. Estimates suggest that ADCs could account for a substantial portion of the global cancer market, reaching $31 billion out of $375 billion by 2028. The value of the market for these drugs was already estimated to be around $9.7 billion in 2023, highlighting its significant potential for growth.
The “fear of missing out” (FOMO) is driving many businesses to enter the ADC market. Companies are eager to gain exposure to ADCs and make them a cornerstone of their corporate strategies. This FOMO is fueled by the momentum ADCs gained in 2023 and is expected to persist in the coming years. The allure of potential profits and the fear of being left behind are strong motivators for businesses to invest in ADCs.
While ADCs have been around for decades, it was only in recent years that dealmaking and innovation in this field started to accelerate. Advancements in ADC technology have made newer iterations of the drugs safer and more effective, instilling confidence in their potential and attracting greater investment. The continuous surge in approvals and acquisitions further bolsters confidence, as ADCs are perceived to have a lower-risk development path.
One notable example of a next-generation ADC is Enhertu, jointly developed by AstraZeneca and Daiichi Sankyo. Unlike older versions, Enhertu has a wider range of treatment capabilities, demonstrating its ability to treat breast cancer patients with different protein levels. Over the years, key components of ADCs have been fine-tuned, maximizing efficacy while minimizing side effects. However, it’s important to acknowledge that ADCs still have limitations, including the development of resistance over time and the occasional failures in clinical trials.
The rise of ADCs has also led to international collaboration, with drugmakers from Japan and China rapidly innovating and bringing new ADCs to the market. Companies from the US and UK are forging licensing agreements and partnerships with these international drugmakers to capitalize on their advancements. Complex ADC technology has become both a motivator and a barrier to entry for companies. The intricacies of ADCs reduce the likelihood of competitors developing biosimilars, allowing drugmakers to maintain high prices for longer periods of time.
Merck and Pfizer, two major pharmaceutical players, are making significant investments in ADCs to drive future growth. Merck has raised its forecast, projecting $20 billion in new cancer drug sales by the early to mid-2030s, thanks in part to its ADC investments. Meanwhile, Pfizer seeks to recover from a difficult year and restore investor confidence by acquiring ADC-developer Seagen for $34 billion. Pfizer’s CEO, Albert Bourla, believes that ADCs are the hottest area of oncology and that the acquisition of Seagen will position Pfizer as a leader in cancer treatment.
The market for ADCs in cancer treatment is undeniably booming, driven by increased confidence, significant investments, and the potential for substantial profits. The landscape of cancer treatment is being transformed by the continued advancements in ADC technology, offering new hope for patients and further opportunities for biotech and pharmaceutical companies. As the industry moves forward, it will be crucial to address the limitations and challenges surrounding ADCs to maximize their potential and improve outcomes for cancer patients worldwide.
