Performance of AMGN’s Key Drugs in Q4

Evenity recorded sales of $599 million in the quarter, up 39% year over year, driven by solid volume growth in the United States. Evenity sales beat the Zacks Consensus Estimate of $565 million.

Repatha generated revenues of $870 million, up 44% year over year, driven by higher volume growth, higher selling price and higher inventory levels. Repatha sales beat the Zacks Consensus Estimate of $812 million.

Prolia revenues came in at $1.05 billion, down 10% from the year-ago quarter due to lower pricing and decreased volume. Prolia sales, however, beat the Zacks Consensus Estimate of $975 million.

Xgeva delivered revenues of $447 million, down 20% year over year, primarily due to lower volume. Xgeva sales missed the Zacks Consensus Estimate of $454 million.

Patents for Prolia and Xgeva expired in February 2025 in the United States and in some European countries in November 2025. Sales of these best-selling drugs are expected to erode significantly in 2026 as several biosimilars have been launched globally.

In oncology, Blincyto generated $413 million in sales, rising 8% from the year-ago period, driven by higher inventory levels and net selling price. Blincyto sales missed the Zacks Consensus Estimate of $435 million.

Sales of Otezla were $625 million in the quarter, flat year over year. Otezla sales beat the Zacks Consensus Estimate of $621 million.

Enbrel revenues of $532 million declined 48% year over year due to lower selling prices (including the impact from increased 340B program mix and Medicare Part D redesign) as well as unfavorable changes to estimated sales deductions. Enbrel sales missed the Zacks Consensus Estimate of $636 million.

Asthma drug Tezspire (tezepelumab) recorded sales of $474 million in the quarter, up 60% year over year, primarily driven by volume growth. Tezspire sales beat the Zacks Consensus Estimate of $421 million.

Amgen has a partnership with AstraZeneca (AZN - Free Report) for Tezspire. Amgen and AstraZeneca share costs and profits equally after AstraZeneca pays a mid-single-digit inventor royalty to Amgen.

While AstraZeneca leads development, Amgen leads manufacturing.

In rare disease, Tepezza sales fell 1% year over year to $457 million due to lower inventory levels and unfavorable changes to estimated sales deductions. Uplizna sales surged 131% year over year to $233 million, driven by volume growth.

New cancer drug Imdelltra (tarlatamab) recorded sales of $234 million in the quarter compared with $178 million in the previous quarter. The drug’s 31% sequential growth was driven by volume growth.

Update on AMGN’s Diabetes/Obesity Pipeline

Amgen is developing MariTide, a GIPR/GLP-1 receptor, as part of its comprehensive MARITIME phase III program in obesity. The candidate is being developed as a single dose in a convenient autoinjector device with a monthly and maybe less frequent dosing. This key feature differentiates it from Eli Lilly (LLY - Free Report) and Novo Nordisk’s (NVO - Free Report) popular GLP-1-based obesity drugs, Zepbound and Wegovy, which are weekly injections.

With MariTide, Amgen intends to take on LLY and NVO, which currently dominate this space with their respective injectable GLP-1 therapies.

Amgen is evaluating MariTide across a broad range of cardiometabolic indications, with obesity at the center of its development strategy. Six global phase III studies are underway for MariTide.

Enrollment has been completed in two pivotal late-stage studies — MARITIME-1 and MARITIME-2 — which are evaluating the drug in patients with obesity, with and without type II diabetes, respectively.

Enrollment is ongoing in two other phase III studies, MARITIME-CV and MARITIME-HF, for the study of atherosclerotic cardiovascular disease and heart failure, respectively. Amgen also recently initiated two other phase III studies evaluating MariTide in obstructive sleep apnea.

The company also plans to initiate phase III studies on MariTide in people living with type II diabetes later in 2026.

Amgen is also advancing its early-stage portfolio for obesity and obesity-related conditions. This includes AMG 513, which is currently in phase I development.
