Understanding the High Costs of Immunotherapy in Cancer Treatment
Written on
Chapter 1: The Promise of Immunotherapy
Immunotherapy represents a groundbreaking approach in the battle against cancer by retraining the immune system to identify and attack cancer cells. Unlike traditional methods such as chemotherapy and radiation, which indiscriminately target both cancerous and healthy tissues, immunotherapy offers a more targeted strategy.
For instance, chimeric antigen receptor T-cell therapy (CAR-T) involves extracting a patient’s T-cells, genetically modifying them to recognize specific cancer cell proteins, and reintroducing them into the patient’s body. This tailored treatment allows the modified T-cells to effectively seek out and eliminate cancer cells.
Another form of immunotherapy is immune checkpoint inhibitors, which focus on the molecular 'brakes' of the immune system, including CTLA-4 and PD-1. These inhibitors enhance the immune response, enabling it to better identify and destroy cancerous cells. The significance of this advancement was recognized with the 2018 Nobel Prize in Physiology or Medicine, underscoring its pivotal role in contemporary cancer care.
These innovative therapies are proving beneficial, particularly for patients who had limited options just a decade ago, significantly enhancing survival rates across various cancer types.
Section 1.1: The Challenge of Drug Pricing
Despite the advancements, the high costs of immunotherapy pose a significant challenge. Ezekiel Emanuel, a prominent figure in medical ethics, emphasized in the Wall Street Journal that the potential transformation in cancer treatment is hindered by exorbitant drug prices, necessitating a reevaluation of pricing strategies.
The oncology landscape remains dynamic, shifting toward targeted and combination therapies. In 2016, over 600 molecules were in late-stage development, with 90 percent classified as targeted treatments. As cancer cells develop resistance to therapies, combining existing and novel treatments will be essential, further escalating costs.
Between 2012 and 2016, global expenditures on oncology drugs and supportive care surged from $91 billion to $113 billion, with nearly half attributed to the U.S. Cancer care costs are projected to continue climbing, potentially reaching $173 billion by 2020.
The average annual expense for cancer medications skyrocketed from under $10,000 in 2000 to over $120,000 in 2015, while the average income for a family of four declined by 8 percent to $52,000, intensifying the financial strain on patients.

Section 1.2: The Impact of CAR-T Therapy Pricing
Recent CAR-T therapies, such as Novartis' Kymriah and Gilead Sciences' Yescarta, come with staggering price tags ranging from $373,000 to $475,000 per patient, influenced by the individualized nature of these treatments, which require extensive laboratory work over several weeks.
Pharmaceutical companies defend their pricing by pointing to the significant investments made in research and development and the hefty costs associated with bringing a drug to market—often exceeding $1 billion. They also claim to offer 'significant discounts' to many patients.
While the annual costs of immunotherapy exceed those of most other cancer treatments, they might still be seen as 'affordable' when compared to the potential $2 million hospital bills faced by leukemia patients throughout their treatment journey.
Mark Faries, director of therapeutic immunology at the John Wayne Cancer Institute, suggested that if a therapy proves to be curative, its overall costs could be lower than those of multiple courses of less effective treatments like chemotherapy.
Chapter 2: Exploring Solutions to Drug Pricing
To address the high costs of drugs, legislative changes may be necessary. Proposed initiatives, such as the Medicare Negotiation and Competitive Licensing Act of 2018, aim to negotiate prices for drugs covered under Medicare Part D. However, many patients utilizing immunotherapy are not on Medicare, with over 175 million Americans relying on private insurance that may not benefit from these negotiations.
Additionally, alternative methods to lower drug costs exist. In September 2017, the National Institute for Health and Care Excellence (NICE) in the UK recommended Bristol-Myers Squibb’s Opdivo for certain lung cancer patients contingent on a negotiated discount.
“This new arrangement allows us to provide patients access to a promising treatment while further evidence of its value is gathered,” stated Carole Longson, director of NICE's health technology evaluation center.
While finding a straightforward solution to the high costs of innovative cancer immunotherapies is complex, the necessity for accessible and effective treatment for patients is undeniable.
