HEAD & NECK CANCER THERAPEUTICS MARKET TRENDS

Growing Emphasis on Perioperative Immunotherapy is a Key Market Trend

Some of the most important global head & neck cancer therapeutics market trends include the increasing transition toward a curative-intent treatment option. Historically, the treatment of head & neck cancer centered on patients with advanced stages of the disease. However, in recent times, new regulatory approvals have increasingly centered on treating the much larger, newly diagnosed locally advanced patient population. If market innovators are able to prove that high-cost biologics such as PD-1 inhibitors provide considerable benefit in these patients, an increasing number of providers may eventually standardize PD-L1 testing. This could lead to surging patient volumes and an extended revenue realization window. Furthermore, major players such as Merck are also focusing on developing innovative drug delivery methods, such as subcutaneous formulations with quicker delivery times, to reduce the time spent in treatment.

• For instance, in May 2025, the KEYNOTE-689 clinical trial, which investigated the perioperative use of the PD-1 inhibitor pembrolizumab, showed improved event-free survival at the 2025 American Association for Cancer Research (AACR) Annual Meeting.

MARKET DYNAMICS

MARKET DRIVERS

Growing Patient Population Base for Head & Neck Cancer to Drive Market Growth

One of the most important drivers of the global market is the rising incidence and substantial patient population base for head & neck cancer. The market is growing strongly due to the considerable global patient pool, as even a modest surge in the number of diagnosed cases or patients accessing treatment can lead to a significant rise in the patient volumes receiving systemic therapy. Furthermore, various types of head and neck cancers, such as thyroid cancer, have a five-year prevalence, and this set of patients continues to receive long-term follow-up care, which includes systemic targeted therapies, among others. Additionally, in recent times, diagnostic measures such as the measurement of PD-L1 scores in patients have enabled clinicians to prescribe more intensive and higher-cost treatment regimens with proven clinical benefits. These drivers are collectively expected to augment the head & neck cancer therapeutics market growth during the forecast period.

• For instance, according to the data published by the Global Cancer Observatory (GCO) for thyroid cancers in 2022, an estimated 821,214 cases of thyroid cancer were diagnosed worldwide.

MARKET RESTRAINTS

Pricing & Reimbursement Pressures with Drug Supply Shortages to Hinder Market Growth

Several factors pose hindrances to overall market growth, including resistance from healthcare payers to reimbursing certain high-cost therapies, coupled with shortages of critical lifesaving drugs. In the case of high-cost therapies, healthcare payers often respond by imposing tighter controls such as discounting, negotiations, and restrictions on lines of therapy. While these measures can lower therapy costs, they can also slow treatment adoption, even in cases where there is a clear clinical benefit to patients. Another notable drawback restricting market growth is supply chain vulnerabilities, which disrupt the availability of critical drugs such as platinum chemotherapies, including cisplatin. Even when immunotherapies such as Keytruda are available, these chemotherapy agents form the backbone of several combination therapies. The unavailability or shortages of these drugs lead to broader disruption of market growth.

• For example, in November 2025, the American Society of Health-System Pharmacists (ASHP) posted a notice regarding shortages of cisplatin injections from notable manufacturers, including Hikma Pharmaceuticals plc, demonstrating ongoing supply volatilities.

MARKET OPPORTUNITIES

Expansions in New Geographies to Create Opportunities for Market Growth

In recent times, there have been favorable regulatory approvals for head & neck cancer therapeutics in the U.S., especially for perioperative immunotherapy. These approvals are anticipated to create a favorable momentum in other high-growth regions to approve similar premium, high-cost therapies. This provides an important opportunity for global market growth, as favorable regulatory and reimbursement decisions, coupled with treatment uptake in other countries, can significantly increase the number of patients adopting these therapies. The market can be further positioned for accelerated growth if companies move fast with regulatory filings, local clinical trial participations, and health economic packages to boost treatment accessibility.

• For instance, in March 2025, Merck & Co., Inc. announced that it had filed Keytruda (Pembrolizumab) in Japan for the perioperative treatment of unresectable locally advanced head and neck squamous cell carcinoma (HNSCC).

MARKET CHALLENGES

Real-World Access Gaps for Treatment & Capacity Constraints Pose Potential Challenges to Market Growth

Some of the crucial challenges associated with global market growth are access gaps in real-world scenarios despite the presence of regulatory approvals in key regions. The real-world access gaps can arise due to challenges related to payer coverage, hospital budget constraints, and procurement mechanisms. In many countries, especially developing countries, broader access to high-cost therapies often invokes legal challenges and court-mandated access on an individualized, case-by- case basis, followed by administrative complexities. This creates a scenario in which uptake is uneven and procurement volumes are unpredictable. As a result, the potential for broader market growth is significantly limited by bottlenecks in healthcare infrastructure. Suitable healthcare infrastructure, such as radiotherapy capacity, capabilities in imaging and pathology testing, or infusion services are required to support higher and more sustainable market growth rates.

• For instance, in August 2025, research published in the journal JAMA Network Open outlined the access barriers and legal challenges towards the drug Keytruda (pembrolizumab) in Brazil, which has 36 approved clinical indications in Brazil. A significant number of legal cases were filed in relation to this drug in Brazil.
