Market Driver - Increasing prevalence of KRAS mutations in cancers.

KRAS mutations are commonly observed in many cancer types including lung cancer, colorectal cancer and pancreatic cancer. KRAS is a small GTPase protein that behaves like a molecular on-off switch in cell signaling pathways. When KRAS is activated by mutations, it gets stuck in the "on" position and continuously tells cells to grow and divide - even when its not needed. This results in uncontrolled cell growth which can lead to tumor formation. Research shows KRAS mutations are present in around 25% of all cancers and thus understanding and targeting these mutations is critical for developing more effective cancer treatments.

In lung cancer alone, around 22-25% of non-small cell lung cancers (NSCLC) harbour KRAS mutations which make them one of the most common oncogenic drivers. NSCLC accounts for around 85% of all lung cancers, which is the leading cause of cancer deaths globally. Similarly, around 40-50% of colorectal cancers and as high as 90% of pancreatic cancers have KRAS mutations. With ageing populations and changing lifestyle habits, the worldwide incidence and mortality rates of cancers like lung cancer, colorectal cancer and pancreatic cancer are steadily increasing in recent years. This unfortunately translates to a growing pool of patients who have tumor cells with problematic KRAS mutations. With limited treatment options currently available for KRAS-driven cancers, successful development of KRAS inhibitors will be crucial in fulfilling this significant unmet medical need.

Market Driver -Advancements in drug discovery and development

Researchers have long been working on developing molecules that can directly target and inhibit KRAS for cancer treatment. However, targeting KRAS had been considered one of the toughest challenges in drug development due to its unusually flat shape and lack of accessible pockets where molecules could bind. Nevertheless, advancements in technologies like DNA sequencing, genomics, structural biology and computational modeling are continuously providing new insights into the function and behavior of KRAS at the molecular level. This improved understanding of KRAS biology has helped researchers identify molecules that can potentially disrupt KRAS signaling in cancers.

Several pharmaceutical companies and research institutions have now progressed candidate KRAS inhibitors into clinical trials. While initial molecules were unsuitable due to toxicity or lack of efficacy issues, refinement of molecular properties, delivery methods and combination regimens through ongoing clinical experience is helping improve therapeutic indices. Some trial agents have shown signs of antitumor activity even in heavily pretreated patients. At the same time, the development of laboratory techniques like CRISPR gene-editing and organ-on-chip models that better recapitulate human tumor biology are enabling more efficient screening and testing of novel KRAS inhibitor entities. All these scientific and technological developments in drug design as well as preclinical and clinical evaluation processes support an optimistic outlook for the successful approval of KRAS inhibitors in the coming years.

Market Challenge - Difficulties in targeting the KRAS protein due to feedback mechanisms.

One of the major challenges faced in the global KRAS inhibitors market is effectively targeting the KRAS protein due to complex feedback mechanisms. KRAS is a protein that plays a key role in cell signal transduction pathways. When KRAS is mutated, it gets stuck in an "on" position and signals cells to multiply uncontrollably, leading to cancer. Researchers have struggled to directly inhibit KRAS as it turns on and off rapidly and engages in elaborate feedback loops with other proteins and molecular pathways. Any attempt to block its signaling through conventional small-molecule inhibition has led to compensatory activation of alternative routes that circumvent the blockade. This feedback activation has hindered the development of effective KRAS inhibitors. Substantial research efforts over decades have failed to identify drug compounds that can potently and selectively inhibit the KRAS signal. The dynamic networks and redundancies in KRAS-mediated signaling pose formidable challenges to drug developers. Overcoming these feedback mechanisms will be critical to advance the field of KRAS inhibitor therapeutics.

Market Opportunity- Rising collaborations and partnerships among key players.

One major opportunity in the KRAS inhibitors market is the rising number of collaborations and partnerships between key industry players. Given the difficulties in developing effective KRAS inhibitors independently, pharmaceutical companies and research institutions are increasingly partnering to pool their knowledge, capabilities and resources. This allows them to tackle the complex problem of KRAS inhibition from multiple angles. Notable partnerships in recent years include collaborations between Amgen with Mount Sinai for KRAS(G12C) research, Mirati Therapeutics with Novartis for the development of MRTX849, and Daiichi Sankyo with AstraZeneca for DS-6051. Such partnerships accelerate research progress by enabling cross-functional working, shared risks, and larger drug development programs. They also help companies strengthen their pipelines. If successful, these collaborations are expected to yield more KRAS inhibitor drug candidates entering clinical trials in the coming years. This rising partnership activity bodes well for innovations and future growth within the KRAS inhibitors market.

Amgen adopted an early market entry strategy by gaining FDA approval for sotorasib (Lumakras) in May 2021, making it the first ever approved drug to directly target KRAS G12C mutations. This gave Amgen a strong first-mover advantage in the market. Lumakras demonstrated significant anti-tumor activity and manageable safety in clinical trials, establishing its efficacy. Amgen has invested heavily in promoting Lumakras and educating physicians about its benefits. This early leadership has helped Amgen capture a major share (~40%) of the nascent KRAS inhibitor market.

Mirati Therapeutics is pursuing an indications expansion strategy. After gaining FDA approval for adagrasib for patients with lung cancer positive for the KRAS G12C mutation in May 2022, Mirati is conducting multiple clinical trials evaluating adagrasib across various solid tumors. It reported positive results from the KRYSTAL-1 trial in colorectal cancer in 2022. By establishing the use of adagrasib across a broader patient pool, Mirati aims to increase its market share.

Johnson & Johnson adopted a strategic partnerships route, collaborating with Novartis to jointly develop and market JNJ-61186372. By leveraging Novartis' oncology expertise and commercial infrastructure, J&J can accelerate the drug's progress and maximize its revenue potential if approved. The partnership de-risks late-stage development by sharing costs. J&J retained US and Japan rights while giving Novartis Europe, ensuring strong commercial coverage globally.
