Shares of Summit Therapeutics Inc. (SMMT) soared by more than 270% on Thursday following the announcement that its investigational cancer drug, ivonescimab, outperformed Merck & Co. Inc.’s (MRK) Keytruda in a late-stage clinical trial. This groundbreaking result positions ivonescimab as a potential new frontrunner in the treatment of non-small cell lung cancer (NSCLC).
The clinical trial rigorously compared ivonescimab to Keytruda in patients with NSCLC whose tumors expressed the protein PD-L1. Ivonescimab demonstrated a statistically significant improvement in progression-free survival (PFS) across various patient subgroups, encompassing those with both high and low PD-L1 expression. This noteworthy achievement marks a significant milestone for Summit Therapeutics, which reported the findings in a press release.
Robert Duggan, Summit’s chairman and CEO, highlighted the unprecedented nature of the results, stating, “We are not aware of any previous phase 3 trials in NSCLC that have shown a statistically significant improvement over Keytruda in a direct comparison. This represents a potential paradigm shift in treatment options for cancer patients.”
Lung cancer remains the leading cause of cancer-related deaths in the United States, as per the Centers for Disease Control and Prevention (CDC). Non-small cell lung cancer constitutes approximately 80% to 85% of all lung cancer cases, underscoring the critical need for effective treatments in this area.
Summit Therapeutics plans to further develop ivonescimab not only for NSCLC but also for other types of tumors. This strategic move aims to expand the potential impact of the drug across various cancer types, addressing a broader patient population.
Keytruda, Merck’s leading product, generated over $25 billion in sales last year, reflecting a 19% increase from the previous year. However, the Summit announcement triggered a drop in Merck’s stock price, which declined by 1.1% on Thursday, after initially gaining ground earlier in the day.
The surge in Summit’s stock reflects growing investor confidence in ivonescimab’s potential. Year-to-date, Summit shares have skyrocketed by 318%, compared to the S&P 500’s (SPX) increase of 9.8%.
Key Takeaways:
- Ivonescimab’s Success: Summit Therapeutics’ ivonescimab showed superior performance to Merck’s Keytruda in a late-stage trial for NSCLC.
- Statistically Significant Improvement: The trial results highlighted a significant improvement in progression-free survival across different patient subgroups.
- Paradigm Shift Potential: Summit’s CEO, Robert Duggan, emphasized the unprecedented nature of the trial results, suggesting a potential shift in cancer treatment paradigms.
- Broader Development Plans: Summit intends to pursue further development of ivonescimab for NSCLC and other tumor types.

Conclusion:
Summit Therapeutics’ announcement of ivonescimab’s success against Keytruda marks a pivotal moment in the field of oncology. The significant improvement in progression-free survival in NSCLC patients indicates a potential shift in treatment options that could benefit many patients. As Summit plans to expand ivonescimab’s application to other tumor types, the future of cancer treatment may see substantial advancements. Investors have responded positively, evidenced by the remarkable surge in Summit’s stock, while Merck faces a new competitive challenge in the oncology market.
