Merck also expects $15 billion sales from its cardiometabolic drug candidates in mid-2030s. (Merck) While some Merck & Co. investors may still get the heebie-jeebies when thinking about Keytruda’s patent cliff in 2028, but the company’s CEO Rob Davis now thinks “it’s just another year.” Make no mistake, given Keytruda’s size, an overall business decline will likely still hit. But Merck is focused on making “the hill to dip as small as possible and the return to growth as fast as possible,” Davis said Monday at the 2024 annual J.P. Morgan Healthcare Conference.
“I know that the conversation continues to be about Keytruda and 2028,” Davis said. “But increasingly, we’re not focused on 2028. 2028, it’s just another year, it’s just another point. We’re focused on 2030 to 2040.” At last year’s J.P. Morgan conference, Merck laid out a projection to potentially have more than $10 billion in sales from oncology drug candidates in its pipeline. On Monday, Davis increased that number to more than $20 billion by mid-2030s. “One of the concerns that someone might have in relationship to an [individualized neoantigen therapy] that’s based on mRNA is the durability,” Li said. “What you see with the press releases that come up […] that durability is real. When you treat in earlier stage, and you have that [durable effect], that’s when a patient starts thinking the word potential cure.”
Keytruda itself is currently undergoing a key launch in early-stage NSCLC. The FDA doled out the first-in-class approval for continuous use of Keytruda both before surgery in the neoadjuvant setting and after surgery as an adjuvant therapy in October based on an overall survival win from the Keynote-671 trial. Merck has previously cautioned a slow sales ramp for an earlier nod that allows Keytruda solely as an adjuvant therapy. But Davis and Li during Monday’s presentation adopted a much more bullish tone for the neoadjuvant-plus-adjuvant indication. Li called the Keynote-671 overall survival readout a “watershed moment.” The Keytruda regimen is now the only checkpoint inhibitor that boasts the highest Category 1 recommendation on the National Comprehensive Cancer Network guidelines for early-stage lung cancer, Li noted. With proper screening, 8 out of 10 Keytruda patients in metastatic NSCLC could be eligible for the PD-1 inhibitor in an earlier stage, he said. Merck and other PD-1 developers have made heavy investments in early-stage cancers. Eight indications in early-stage tumors drove about 20% of Merck’s total global revenue in 2023, and Davis said the company expects to reach 25% in 2024. And the company has more than 20 registrational studies in other adjuvant areas. Davis suggested that because Keytruda is used more often as a single agent in early-stage disease, that gives a potential subcutaneous version of Keytruda a better chance to soften the blow when the original infused formulation loses market exclusivity in 2028. For the perioperative NSCLC indication, Keytruda is given alongside chemotherapy before surgery for up to four cycles and then as a monotherapy after surgery for up to 13 cycles.
