Keytruda Market Insights, By Treatment Regimen - Monotherapy Segment’s Dominance is Driven by Efficacy and Safety Profile

The monotherapy segment is on the top of the global Keytruda market in treatment regimen with an estimated share of 57.9% in 2025, thus it surpasses the combination therapies in terms of market share. The main reasons for the strong monotherapy position are its simple therapeutic approach, which encourages patient adherence and lessens the complexity of treatment protocols.

Keytruda (pembrolizumab), being a single-agent immune checkpoint inhibitor that acts on the PD-1 pathway, has provided significant efficacy when used alone across a variety of cancer types. This has led to the simplification of dosing schedules and prevention of overlapping toxicities, which are usually associated with combination regimens.

Keytruda Market Insights, By Indication - Melanoma Leads Due to Unmet Medical Needs and High Responsiveness

The melanoma segment has been the largest contributor to the global Keytruda market and its share stood at an estimated 12.5% in 2025. A number of factors exist behind the assertion that melanoma is the main indication for Keytruda therapy. For a long time, advanced melanoma had not been treated with efficient dosages and the disease had poor prognosis along with a considerable unmet medical need.

In May 2025, CytomX Therapeutics, a U.S. biotech developing conditionally activated cancer therapies, announced that the first patient was dosed with its investigational drug CX-801 plus Keytruda in a phase 1 metastatic melanoma trial. The company is testing the combination to address PD-1 refractory disease, aiming to assess safety and early antitumor activity.

Reimbursement Scenario for Keytruda

• In the U.S., Keytruda carries a high list price, but most insured patients pay little or nothing because commercial plans, Medicare Advantage, Medicaid, and Merck’s support programs absorb most costs. Out-of-pocket exposure becomes significant only for traditional Medicare patients without supplemental coverage and for uninsured patients who face prices close to the full WAC.
• Canada applies stricter value filters. The drug is reimbursed only for defined NSCLC patients and only if prescribed by specialists and priced below current levels, as the ICER exceeds accepted thresholds. Budget-impact estimates show a meaningful public-payer burden, so access remains conditional rather than broad.

Keytruda Market Dynamics

Keytruda Market Driver - Rising Cancer Incidence Globally

The rising cancer incidence worldwide continues to sustain clinical demand for PD-1/PD-L1 therapies, but this demand no longer translates into strong revenue growth for Keytruda. The market now faces structural decline due to biosimilar pressure, shifting reimbursement policies, and rapid diversification of immunotherapy options. As more patients enter treatment pathways earlier, payers increasingly push for cost-effective alternatives, accelerating the erosion of Keytruda’s premium pricing. The expanding use of competing IO regimens and growing adoption of next-generation targeted therapies further dilute Keytruda’s share, causing the market to contract even as underlying oncology cases rise.

In February 2025, WHO reported cancer remains a leading cause of death, responsible for nearly 10 million deaths in 2020, or one in six deaths. The most common cancers include breast (2.26 million cases), lung (2.21 million cases), colon and rectum (1.93 million cases), and prostate (1.41 million cases). Tobacco use, obesity, alcohol, and poor diet contribute to one-third of cancer deaths. Human papillomavirus (HPV) and hepatitis cause about 30% of cancer cases in low-income countries. Keytruda from Merck continues to make progress in treating cancers like lung and breast. Early detection and treatment can cure many cancers, improving survival rates worldwide.

Keytruda Market Opportunity - Launch of New Combination Regimens with Keytruda

The new combination regimens introducing KEYTRUDA (pembrolizumab) are a big macroeconomic factor in the global Keytruda market. As an instance of the immune checkpoint inhibitor targeting the PD-1/PD-L1 pathway, KEYTRUDA has already claimed its position as one of the front-line immuno-oncology therapies for a variety of cancer indications. The combination of KEYTRUDA with other novel agents such as chemotherapy, targeted therapies, or immunomodulatory drugs not only enhances treatment efficacy but also leads to better patient outcomes and addressing cancer types that are still resistant to the monotherapies.

In August 2025, the U.K.'s National Institute for Health and Care Excellence (NICE) recommended the combination of Padcev and Keytruda for metastatic urothelial carcinoma (mUC) treatment. Astellas Pharma, known for its innovative therapies, and MSD, a leading healthcare company, worked with NHS England to make this treatment cost-effective. The combination was previously approved by the U.S. FDA in December 2023 and later by the European Commission and MHRA in 2024. Padcev and Keytruda showed a 55% reduction in disease progression or death in clinical trials.

Analyst Opinion (Expert Opinion)

• Technological innovations made in the field of immuno-oncology have, along with the backing from the regulatory authorities and the global intake of the effective cancer treatments, contributed to the Keytruda market growth. Its wide application across different oncology areas together with the seen effectiveness are the reasons for it being a mainstay in the oncology industry. Growing markets and partnerships between Big Pharma and governments are bringing new chances, but on the other hand, aspects, like the high pricing and the expiration of patents, could have a negative impact on the market size increase.
• The AACR Annual Meeting and similar events have been major contributors to the dissemination of knowledge and the conducting of policy discussions around immunotherapies like Keytruda in the recent past. The collaboration between MSD and Astellas Pharma is an example of a partnership that has resulted in the development of combination therapies, which in turn have helped improve the patients' responses to the treatments. The global movement to make these treatments available to more patients is influencing the market future beliefs that it will be favorable.
