The Checkpoint Inhibitor Refractory Cancer Market is poised for remarkable expansion, with projections indicating it will soar to an impressive US$ 19.1 billion by 2030, marking a substantial leap from the US$ 3.4 billion recorded in 2023. This trajectory of growth is underpinned by a robust Compound Annual Growth Rate (CAGR) of 27.8% during the forecast period from 2023 to 2030.

Checkpoint inhibitors, a pivotal category of cancer immunotherapy, serve to activate the immune system, empowering it to identify and target cancer cells. However, a significant challenge arises as many patients inevitably develop resistance to these therapies over time. In this context, refractory cancer denotes disease progression following treatment with conventional approaches like chemotherapy or checkpoint inhibitors. The prevalence of cancer on a global scale, coupled with the escalating instances of acquired resistance, emerges as the driving force propelling growth within the refractory cancer market.

The Checkpoint Inhibitor Refractory Cancer Market revolves around pharmaceutical therapies designed to cater to cancer patients who have ceased responding to initial checkpoint inhibitor treatments. Checkpoint inhibitors represent a pioneering form of immunotherapy, facilitating the immune system's capacity to recognize and combat cancer cells. Refractory cancer, conversely, signifies the progression of the disease following the utilization of standard treatment protocols.

The market's meticulous segmentation strategy incorporates diverse elements such as mechanism of action, cancer type, line of therapy, route of administration, and geographic region. Among these facets, the PD-1/PD-L1 inhibitor segment takes precedence, contributing to the largest market share, surpassing 40% in 2022. PD-1/PD-L1 inhibitors hold the distinction of being the most widely employed class of checkpoint inhibitors. Nevertheless, the development of resistance to these inhibitors is a common occurrence, giving rise to a demand for innovative therapeutic approaches. The advent of novel inhibitors, including IDO1 and A2AR, is making substantial contributions to the growth of this segment.

A recent exemplar of industry advancements lies in Amgen's Lumakras, which received FDA approval in September 2022. It was granted approval for use in combination with Merck's Keytruda, particularly for patients with KRAS-mutated non-small cell lung cancer who had previously undergone checkpoint inhibitor immunotherapy. This development underscores the ongoing pursuit of innovative solutions within the checkpoint inhibitor refractory cancer market, offering renewed hope and therapeutic options for patients grappling with treatment resistance.

• The market has a mix of big pharma companies with high focus on branded checkpoint inhibitors, along with smaller biotech firms developing niche inhibitors and novel platforms.

Checkpoint Inhibitor Refractory Cancer Market Drivers:

The rising prevalence of cancer globally is a major factor driving growth in the checkpoint inhibitor refractory cancer market. As per WHO estimates, cancer cases are expected to rise by 60% over the next 20 years, from 14 million new cases in 2012 to 22 million cases in 2030. The growing cancer burden is leading to increasing utilization of treatments like chemotherapy, targeted therapy, and immunotherapy. However, a majority of cancer patients develop resistance to these initial treatments over time, creating demand for newer therapies in the refractory setting.

Another key driver is the rising cases of resistance and reduced response to existing checkpoint inhibitor immunotherapies like PD-1, PD-L1 and CTLA-4 inhibitors. Though checkpoint inhibitors revolutionized cancer treatment, most patients eventually become refractory. For instance, in NSCLC, the response rate with anti-PD-1 monotherapy is only around 20%. This is fueling research into novel inhibitors and combination approaches to overcome resistance.

The robust pipeline of investigational therapies that target mechanisms of resistance is also driving market growth. Companies are developing inhibitors of LAG3, TIGIT, IDO1, adenosine A2a receptor, and other immune pathways. Several combination approaches using PD-1/PD-L1 inhibitors along with CTLA4 inhibitors, chemotherapy, or targeted therapies are being explored to improve outcomes.

Growing investments in R&D in this niche area presents growth opportunities. In 2022, Merck acquired cancer immunotherapy developer Imago BioSciences for $1.35 billion to expand its pipeline. Amgen also acquired FivePrime Therapeutics for $1.9 billion to gain its CSF1R inhibitor. The strong interest amongst big pharma companies to expand their oncology pipeline is driving R&D activity.

Checkpoint Inhibitor Refractory Cancer Market Opportunities:

The development of predictive biomarkers to identify patients unlikely to respond to checkpoint inhibitors presents an opportunity to develop targeted therapies. Companies are focused on biomarker-driven clinical trials and companion diagnostic development. For instance, IdentifyMets is developing a gene expression test to identify cancer patients unlikely to respond to Keytruda.

Novel platforms like mRNA vaccines, oncolytic viruses, bispecific antibodies and CAR T-cell therapies hold promise in overcoming resistance mechanisms. Moderna recently started Phase 1/2 trials of its personalized cancer vaccine in combination with Keytruda for high-risk melanoma. Oncolytic viruses like Amgen’s T-Vx-ND are also being evaluated to boost anti-tumor immunity.

Emerging evidence that gut microbiome impacts response to checkpoint inhibitors offers potential opportunities. Multiple research groups are exploring microbiome modulating therapies to enhance immunotherapy efficacy. Early results from microbiome editing company Seraxis in melanoma are encouraging. Similar approaches could help overcome resistance.

The rising popularity of dual checkpoint inhibitor combinations presents an opportunity for long-term market growth. Though associated with higher toxicity, combinations like Opdivo and Yervoy have shown superior efficacy in difficult-to-treat cancers. Dual combinations targeting various immune pathways are a promising approach.
