Key Insight

👉 Merck is transitioning from single-drug dominance → diversified oncology platform

In 2024, Merck's oncology sales were a major driver of its pharmaceutical revenue, with cancer drug sales reaching approximately $32.7 billion. This includes Keytruda (pembrolizumab), Merck's flagship immuno-oncology therapy, which alone generated about $29.5 billion in sales, marking an 18% increase year-over-year. Other oncology products contributing to growth included Welireg, which saw a 133% increase to $509 million, and increased alliance revenues from Reblozyl and Lynparza. Overall, Merck's pharmaceutical sales grew 7% to $57.4 billion in 2024, with oncology being the primary growth area (1569).

As anyone who has been following the I-O (immuno-oncology) race knows, lung cancer is the most competitive field for the new generation of cancer fighters, and that’s because it represents a mammoth market—and financial opportunity. Currently, Keytruda leads rivals from Bristol-Myers, AstraZeneca, Roche and the Pfizer-Merck KGaA team in that department, boasting two approvals in the front-line setting to their collective zero.

Keytruda has also impressed in plenty of other cancer types, winning green lights in cancers including head and neck, cervical, lymphoma and more. Its indications across nine collective cancer types will all chip in sales that’ll contribute to its forthcoming leap.

*The name KEYNOTE is not an acronym but rather a code that identifies specific clinical trials for the immunotherapy drug Keytruda (pembrolizumab). Merck & Co., the manufacturer of Keytruda, assigns a unique KEYNOTE number to each clinical study to track research into the drug's effectiveness for different cancers and treatment regimens.

In 2024, Merck's Keytruda (pembrolizumab) achieved global sales of approximately $29.5 billion, representing an 18% increase compared to 2023. Excluding foreign exchange impacts, the growth was about 22%. Keytruda remained the world’s best-selling drug, with multiple FDA approvals in 2024 expanding its indications, including treatments for cervical and endometrial cancers (12346).

After AbbVie's Humira lost U.S. market exclusivity and as demand for COVID vaccines plummeted at the end of the pandemic, Merck & Co.’s Keytruda was finally able to claim the title of the world’s bestselling medicine in 2023. But its reign may be short-lived. 

In 2023, Keytruda’s sales grew 21% at constant exchange rates, reaching $25 billion. At the same time, as GLP-1 diabetes and obesity drugs take the world by storm, Novo Nordisk’s semaglutide franchise—Rybelsus, Ozempic and Wegovy—together generated 145.8 billion Danish kroner ($21.1 billion). That marked a nearly 90% surge over 2022. 

The three semaglutide brands continued their seemingly unstoppable growth into 2024. Their first-quarter sales collectively jumped 48% year over year to 42.2 billion Danish kroner ($6.1 billion), inching even closer to Keytruda’s $6.9 billion haul, which represented a 20% increase over the same period last year. 

Keytruda is no doubt the world's bestselling cancer drug. The next oncology asset on our list, Bristol Myers Squibb and Ono Pharma’s rival PD-1 inhibitor Opdivo, generated $10 billion last year. Johnson & Johnson recorded $9.7 billion for its anti-CD38 multiple myeloma drug Darzalex. 

In October 2023, the FDA greenlighted Keytruda as part of a continued neoadjuvant-adjuvant therapy used around surgery in resectable non-small cell lung cancer, making it the first PD-1/L1 inhibitor regimen that’s used both before and after surgery. 

The approval was accompanied by phase 3 data from the KEYNOTE-671 trial showing that, compared with presurgical chemo alone, the addition of Keytruda around surgery significantly cut the risk of death by 28%. Despite perioperative Keytruda’s overall survival win, it remains unclear whether a checkpoint inhibitor is necessary both before and after surgery for all approved non-small cell lung cancer cases. The FDA has indicated it wants to tease out the exact contribution of each phase of treatment to the entire regimen. The ultimate length of treatment will affect Keytruda’s long-term sales potential.

In another major feat, a combination of Keytruda and Astellas and Pfizer’s Padcev won full FDA approval as a first-line treatment for advanced bladder cancer—regardless of the patient’s eligibility for chemotherapy. The approval came after the phase 3 EV-302 trial linked the Keytruda-Padcev combo to a 53% reduction in the risk of death compared with chemo. 

But the EV-302 readout was viewed as more of a success for Padcev and the antibody-drug conjugate modality, especially given Keytruda’s previous stumbles (Lancet Oncology 2021) in first-line bladder cancer as a monotherapy and as part of a combination with traditional chemotherapy. Nevertheless, the EV-302 regimen speaks to Keytruda’s appeal as the combination partner of choice for newer drugs. Another candidate taking that approach is Moderna and Merck’s individualized cancer vaccine, mRNA-4157 (V940). The shot’s cocktail with Keytruda has drawn much interest because of its promising midphase data in resected melanoma.  

However, not all attempts to pair Keytruda up have been successful. Some of the notable failures include Keytruda’s combos with AstraZeneca-partnered Lynparza and Eisai-shared Lenvima.

As Keytruda is slated to fall off the patent cliff in 2028, Merck has been working on a subcutaneous version to potentially soften the blow. However, Merck is behind its rivals BMS and Roche in terms of developing more convenient injections of their PD-1/L1 offerings. A dispute over a microscopic enzyme is threatening Merck & Co. plans to sell a new version of Keytruda, the cancer drug that generates nearly half of the company’s sales. Merck has been tweaking Keytruda to make it easier to use—and to protect billions of dollars in revenue the company could lose after U.S. patent protection runs out in 2028 and rivals can begin selling copycats. The enzyme in the new Keytruda allows it to be injected, rather than given intravenously. It is the subject of a brewing patent dispute between Merck and a biotech called Halozyme Therapeutics. (Wall Street Journal

While biosimilars for pembrolizumab are on the horizon, as of mid-2025 no biosimilar versions are yet widely available or approved for commercial use in key global markets. These drugs are biologics (monoclonal antibodies), which are complex to manufacture and subject to patent protections. Pembrolizumab’s patent (held by Merck) is expected to expire in the US around 2028, potentially allowing biosimilars (not generics, due to biologics’ complexity) to enter the market thereafter. Biosimilars are highly similar versions of biologics, requiring clinical trials to demonstrate equivalence, unlike small-molecule generics.

Some countries (e.g., India, China) may produce biosimilar or off-patent versions of ICIs, but these are not FDA- or EMA-approved and lack global standardization. For example, biosimilars for other biologics (e.g., rituximab) exist in India, but no specific pembrolizumab biosimilar is available in major markets.

The Biologics Price Competition and Innovation Act (BPCIA) grants a 12-year exclusivity period for original biologics in the US. Since Keytruda was first approved by the FDA on September 4, 2014, this exclusivity* is scheduled to expire on September 4, 2026 (Eureka). While this could theoretically allow for biosimilar applications, the stronger patent protections, which expire in 2028, are the main barrier to market entry.

*Note: Patent Protection vs Regulatory Exclusivity: Patent protection protects the inventor's intellectual property, including the drug molecule itself and its manufacturing process. Regulatory exclusivity prevents competitor products from entering the market, regardless of patent status. This is distinct from patents and applies to biologic drugs like Keytruda.

Key Insight

👉 Roche is transitioning from legacy biologics → next-gen precision oncology

In 2024, Roche's cancer-related sales, encompassing oncology and hematology, totaled CHF 23.7 billion (approximately USD 26.9 billion). Within this, oncology sales reached CHF 15.8 billion (about USD 17.9 billion), while hematology sales were CHF 7.9 billion (around USD 9 billion). This represented a 7% increase at constant exchange rates compared to 2023. Roche's pharmaceutical division overall grew 8% to CHF 46.2 billion (approximately USD 52.5 billion), driven by key cancer drugs such as Phesgo and immuno-oncology therapies including Tecentriq, whose sales were flat at CHF 3.6 billion (USD 4 billion). The company also launched new cancer medicines like Itovebi for hard-to-treat breast cancer during the year, strengthening its oncology portfolio (1245).

The lead for the Swiss drugmaker, which has dominated the cancer landscape for years, is about to get a lot less commanding. 

One big part of Roche’s forthcoming sales stagnation? Biosimilar rivals, which are readying copies of older blockbusters Rituxan, Herceptin and Avastin. Those copycats are expected to roll out over the next few years, with some already on the market overseas.

To fill the void, Roche is looking in part to immuno-oncology product Tecentriq (checkpoint inhibitor), which currently bears approvals in lung cancer and bladder cancer. There’s just one problem: Its rivals do, too, and analysts say Roche’s data doesn’t seem to stack up to competitor Merck’s in the all-important front-line lung cancer market.

That’s not to say the drug can’t find other markets to control, and recently, trial wins have hinted that Tecentriq may just find some key niches. 

Roche is also looking to find new sales avenues for its older drugs through combinations. It’s paired Tecentriq and Avastin in areas such as lung cancer and liver cancer, and it won an FDA approval for a combination of Herceptin and newer breast cancer treatment Perjeta in postsurgery patients, despite data that analysts labeled “weak.”

Roche’s immuno-oncology business underwent some major changes in 2024. The Swiss pharma’s Genentech unit closed its cancer immunology research department and merged its function with molecular oncology research.

Then, a few months later, Roche said the closely watched Skyscraper-01 trial of its TIGIT antibody tiragolumab failed to show an overall survival benefit when combined with Tecentriq in first-line PD-L1-high non-small cell lung cancer, despite an earlier positive signal.

Given the importance of the indication, the trial failure pushed the entire TIGIT idea—once billed as the potential next big immune checkpoint target after PD-1/L1—ever closer to its graveyard. Bristol Myers SquibbMerck & Co. and, most recently, BeiGene, have all ditched TIGIT, although Roche still has a few ongoing phase 3 trials that are fully enrolled.

Also in cancer immunotherapy, Roche last year struck a $1.5 billion deal to purchase its then-partner Poseida Therapeutics, giving the cell therapy field a much-needed injection of confidence. The deal brought to Roche an allogeneic cell therapy platform, which includes a gene editing tool that allows for the delivery of multiple CARs in a single step.

The Poseida buy also strengthened Roche’s flourishing hematology portfolio. Its hemophilia drug Hemlibra grew sales by 12% at constant exchange rates, reaching 4.5 billion Swiss francs last year. Diffuse large B-cell lymphoma (DLBCL) antibody-drug conjugate Polivy crossed the blockbuster threshold with 1.1 billion Swiss francs in 2024. Its two CD19xCD3 bispecifics, Columvi and Lunsumio, are anticipated to receive an FDA decision and a phase 3 readout, respectively, in second-line DLBCL this year.

Overall, Roche has successfully navigated the scary losses of exclusivity of its former top-selling cancer drugs—Avastin, Herceptin and Rituxan. In 2024, group sales went up 3% to about 60.5 billion Swiss francs, including 46.2 billion Swiss francs from the pharma division, which ginned up 4% year-over-year growth.

To fill in Herceptin’s shoes, Roche has put together a multi-asset plan in breast cancer. One of those assets, PI3K inhibitor Itovebi, cleared the FDA last year in certain PIK3CA-mutated HR-positive, HER2-negative breast cancer.

Roche also bought a portfolio of CDK (Cyclin-Dependent Kinase) inhibitors* from China’s Regor Pharmaceuticals last year for $850 million upfront. What’s more, two important phase 3 trials of the company’s oral SERD, giredestrant, could read out this year.

*CDK4/6 inhibitors are a class of medicines used to treat certain types of hormone receptor-positive, HER2-negative breast cancer.

3. Bristol-Myers Squibb

  • 2025 First-Quarter reported a total revenue of USD 11.2 B. 6% decrease year over year.
  • Rank change: None
  • Market Capitalisation: 98.5 B USD

Strength: Deep oncology portfolio led by:

  • Opdivo

  • Revlimid (declining due to generics)

  • CAR-T therapies

Current Situation (2026)

  • Revenue pressure from Revlimid patent cliff

  • Growth driven by:

    • CAR-T therapies (Breyanzi, Abecma)

    • Next-gen immunotherapies

Key Insight

👉 BMS is shifting from legacy blockbusters → advanced cell therapy ecosystem.

  • Bristol Myers Squibb’s Opdivo (nivolumab) is an immunotherapy drug that is used to treat a number of different cancers. Opdivo doesn’t come close to its rival Merck & Co’s immunotherapy Keytruda in terms of sales, but the drug still generated sales of $9 billion in 2024. Thanks to some new indications, Opdivo has seen impressive growth in the last few years, with sales predicted to reach $11.75 billion by 2026. However, BMS cannot afford to rest on its laurels, and they are set to lose the US market exclusively for Opdivo in 2028. Sydney-based company NeuClone Pharmaceuticals, Swedish firm Xbrane Biopharma and China’s Luye Pharma are already working to develop biosimilars. With the loss of exclusivity for not just Opdivo, but also cancer medication Revlimid and Pfizer-partnered blood thinner Eliquis within the next few years, Bristol Myers Squibb is currently working to launch six new drugs, that together could contribute over $15 billion in sales.

Key Insight

👉 AstraZeneca is the most diversified high-growth oncology company

In 2024, AstraZeneca's oncology sales reached approximately $22.35 billion, representing a 21% increase (24% at constant exchange rates) compared to the previous year. Oncology accounted for 41% of AstraZeneca's total revenue of $54.07 billion in 2024.Key cancer drugs driving this growth included:
  • Tagrisso, with sales increasing 20% year-over-year to $1.7 billion, primarily for EGFR-mutated non-small cell lung cancer (NSCLC).
  • Calquence, used in hematologic malignancies, grew 20% due to new approvals in lymphoma.
  • Enhertu, an antibody-drug conjugate, saw a remarkable 48% sales increase, reflecting rapid uptake in HER2-expressing cancers.
  • Lynparza, a PARP inhibitor for breast and prostate cancer, posted a 46% revenue surge following expanded indications.
Other oncology products contributing to sales growth included Zoladex, Imjudo, Truqap, and Orpathys. AstraZeneca also experienced some decline in Faslodex sales due to pricing and generic competition in certain markets.

Overall, AstraZeneca’s oncology segment showed strong momentum in 2024, supported by expanded indications, new patient adoption, and a robust pipeline of innovative cancer therapies. Oncology remained the largest contributor to the company’s revenue growth, underscoring its strategic focus on this therapeutic area (2456).

Perhaps no company has pushed more aggressively into oncology in recent years than AstraZeneca, and that push is set to bump the British drugmaker up on the list by two spots, Evaluate predicts—more than any other drugmaker in the top 10.

One drug that’ll help lead the charge? Imfinzi, AZ’s entrant in the PD-1/PD-L1 class of immuno-oncology products. The drug won a blockbuster nod in previously treated, stage 3 lung cancer, a sizable market that analysts think it’ll have to itself for years to come.

AstraZeneca stole the show at the largest cancer conference (ASCO 2025). AstraZeneca had an impressive slate of top-level plenary talks geared toward using drugs earlier on for breast, gastric, and lung cancer survival.

The biggest splash was from AstraZeneca's drug Imfinzi (durvalumab), which trains a patient's body to attack a protein in their cancer. Imfinzi's already routinely used in some late-stage, recurrent and metastatic cancers (in the treatment of solid lung and liver tumors, for example), but it hasn't been a go-to treatment for earlier-stage cancers.

The results from the company's late-stage phase-3 "Matterhorn" trial (NEJM 2025) presented at the conference, Imfinzi, taken with chemo after surgery, boosted gastric cancer patients' two-year survival rates from 70% (without the immunotherapy) to nearly 76% — a significant jump.

AstraZeneca’s got plenty more going for it in oncology department, though—and it’s been quick to remind investors who are hyperfocused on I-O. For one, it boasts PARP inhibitor Lynparza, which brought in $269 million through the first six months of the year and is riding high on a new breast cancer approval.

Then there’s Tagrisso, a targeted lung cancer drug whose sales grew by 89% year-over-year in H1 to hit $760 million. It’s bolstered by a new indication in first-line EGFR-mutated lung cancer, where it this year became the new standard of care. The EGFR inhibitor king Tagrisso also managed a 13% sales growth to $6.6 billion with two new FDA approvals last year, one in combination with chemotherapy in first-line EGFR-mutated non-small cell lung cancer and the other for stage 3 EGFR lung cancer. But the drug is facing competition from Johnson & Johnson’s cocktail of Rybrevant and Lazcluze.

AZ is also counting on big things from Calquence, expected to challenge Johnson & Johnson and AbbVie juggernaut Imbruvica in blood cancers. While locked in a fierce competition with BeiGene’s rival BTK inhibitor Brukinsa, Calquence was included in the second round of IRA price negotiations.

Following mixed phase 3 data and an FDA resubmission, AZ and Daiichi have in January 2025 won the FDA’s go-ahead for their second ADC, TROP2-directed Datroway, in HR-positive, HER2-negative breast cancer.

5. Johnson & Johnson


  • 2024 cancer sales: $20.78 billion
  • 2025 First-Quarter reported sales growth of 2.4% to $21.9 Billion

Biggest surprise of 2026 earnings season

Q1 2026 Highlights

Key Growth Drivers

  • Darzalex (multiple myeloma)

  • Carvykti (CAR-T therapy)

Strategic Position

  • Strong pipeline + diversified pharma portfolio

  • Raising full-year guidance

Key Insight

👉 J&J is emerging as a top 3 oncology player globally—not just a diversified healthcare company

In 2024, Johnson & Johnson's oncology sales reached approximately $20.78 billion, marking a 17.7% increase year-over-year. This growth was driven by strong performances from key cancer drugs including Darzalex (daratumumab), which alone generated $11.67 billion in sales (up 19.8%), and CAR-T therapy Carvykti, which nearly doubled to $963 million in sales with a 92.7% increase. Other notable oncology products contributing to growth were Erleada (apalutamide), Tecvayli (teclistamab), and Talvey (talquetamab), all focused on hematologic cancers such as multiple myeloma (523).

Johnson & Johnson may not have as wide an oncology portfolio as some of its rivals do, but the products it does have are rock-solid. 

J&J is also a force on the multiple myeloma side with TALVEY® (talquetamab-tgvs) and TECVAYLI® (teclistamab-cqyv).

Its Takeda-partnered Velcade long reigned supreme. The standby is still churning out big numbers—it amassed $1.11 billion in 2017 sales outside the U.S., where J&J markets the drug—but it too has a follow-up ready to lead a new generation of myeloma therapies. That’s Darzalex, which by last year had already generated more for the year than its predecessor at $1.24 billion.

Darzalex’s numbers are only set to keep growing, thanks to a landmark FDA green light in May. The agency gave the drug a go-ahead—in combination with Velcade and prednisone—in previously untreated patients who are transplant-ineligible, making Darzalex the first-ever monoclonal antibody to score an OK in newly diagnosed patients.

And then there’s powerhouse Imbruvica, which J&J has shared with AbbVie since the latter’s buyout of Pharmacyclics. That drug pulled in $1.89 billion last year, and a recent combo approval for patients with Waldenström macroglobulinemia should keep sales on the up and up. AstraZeneca, though, is mounting a challenge with Calquence, a drug that’s expected to eventually take on Imbruvica in chronic lymphocytic leukemia.

6. Celgene


  • 2024 cancer sales: $18.55 billion
  • Rank change: None
In 2024, Celgene’s cancer drug sales were approximately $18.55 billion. This figure reflects the company’s strong oncology portfolio, led notably by Revlimid, a blockbuster drug for multiple myeloma and other blood cancers. Despite controversies over pricing, Revlimid remains a major revenue driver for Celgene. The company ranks among the top oncology drugmakers globally, maintaining its position in the cancer drug market with significant sales growth compared to previous years ($11.65 billion in 2017 to $18.55 billion in 2024) (2).

Celgene’s oncology portfolio also includes other important therapies, and the company continues to focus on innovative cancer treatments and expanding its market presence worldwide (3).

Celgene Corporation, once a leading biopharmaceutical company focused on cancer and immune-inflammatory diseases and headquartered in Summit, New Jersey, was acquired by Bristol-Myers Squibb (BMS) in late 2019. Following the acquisition, Celgene became a wholly owned subsidiary of BMS, with its stock ceasing to trade and its portfolio integrated into BMS’s operations (1).

Revlimid: The Former Flagship

Revlimid (lenalidomide) long dominated Celgene’s—and now BMS’s—cancer portfolio, particularly in multiple myeloma. However, the landscape has shifted significantly. After reaching peak sales of $12.8 billion in 2021, Revlimid’s exclusivity expired, and generic competition has since entered the market. Teva launched the first U.S. generic in 2025, with several other companies following under volume-limited agreements. These deals gradually increase generic market share until all restrictions lift in 20263.

As a result, Revlimid’s revenue is in decline. BMS projected 2025 sales between $9.5 billion and $10 billion, but expects annual drops of $2 billion to $2.5 billion as generics gain ground3. In the first quarter of 2025, Revlimid generated $936 million, down 44% year-over-year54.

Portfolio Evolution and New Oncology Players

With Revlimid’s decline, BMS has shifted focus to other assets, both legacy Celgene drugs and newer therapies:

  • Pomalyst: Another multiple myeloma drug, Pomalyst, also faces generic competition in Europe as of August 2024, contributing to a 24% year-over-year decline in Q1 2025 U.S. sales ($658 million)54.

  • Idhifa: Developed with Agios, Idhifa remains a targeted therapy for relapsed/refractory acute myeloid leukemia (AML) patients with IDH2 mutations. While it was a first-in-class oral inhibitor for this group, its sales are now part of BMS’s broader hematology portfolio.

  • Vidaza: Vidaza, another AML therapy, continues to contribute but is now categorized among BMS’s mature brands4.

  • CAR-T Therapies: BMS has advanced CAR-T therapies, notably Breyanzi, which has become the leading CD19-directed CAR-T product in the U.S., driving growth in hematology4.

  • Reblozyl and Other New Launches: Reblozyl, approved for anemia in beta thalassemia and myelodysplastic syndromes, is now a key growth driver. Alongside it, recent launches such as Breyanzi and deucravacitinib are expected to generate $10–$13 billion in annual sales, offsetting losses from Revlimid’s patent expiry34.

Strategic Shifts and Financial Performance

BMS’s oncology and hematology portfolios are transitioning from legacy Celgene blockbusters to a mix of established and newly launched therapies. In Q1 2025, BMS’s growth portfolio outperformed its legacy products, reflecting this strategic shift4. The company is leveraging its broader pipeline and recent acquisitions to sustain growth despite the erosion of Revlimid and Pomalyst revenues (24).

  • Xtandi (enzalutamide) for prostate cancer, which showed solid sales growth and remains a cornerstone of Astellas’ oncology portfolio.
  • Padcev (enfortumab vedotin) for metastatic urothelial cancer, with sales more than doubling (110% increase) to around ¥117 billion (~$767 million) in the last nine months of 2024.
  • Vyloy (zolbetuximab), a therapy for gastric and gastroesophageal junction cancers, which gained momentum due to faster adoption of Claudin 18.2 biomarker testing.
  • Xospata (gilteritinib) for acute myeloid leukemia and Izervay (avacincaptad pegol) also contributed to revenue growth.
Astellas’ oncology portfolio focuses on cancers such as prostate, bladder, gastric, and blood cancers. The company expects continued growth in oncology driven by these strategic brands, with further expansion anticipated in 2025.

To summarize, Astellas’ 2024 cancer sales were roughly $12.6 billion, fueled by strong performances from Xtandi, Padcev, Vyloy, and other oncology products, marking it as a significant player in the global oncology market.

In 2024, AbbVie’s oncology (cancer) portfolio generated approximately $6.7 billion in global net revenues. This includes key cancer drugs such as Imbruvica and Venclexta, which together account for more than two-thirds of AbbVie’s oncology revenue. Specifically, in the first quarter of 2024, AbbVie reported oncology sales of $1.543 billion, reflecting a 9.0% increase year-over-year (26) .AbbVie’s total net revenues in 2024 were about $56.7 billion, with immunology and oncology as major contributors. While immunology drugs like Skyrizi and Rinvoq showed strong growth, oncology remained a significant segment supported by the company's hematology and cancer therapies (15).To summarize, AbbVie’s 2024 cancer sales were around $6.7 billion, driven mainly by Imbruvica, Venclexta, and other oncology products, with steady growth in the oncology portfolio throughout the year.

Key Insight

👉 Novartis is building a dominant niche in radioligand cancer therapy

In 2024, Novartis’ cancer-related sales were driven primarily by its oncology portfolio, with key products showing strong growth. Notably:
  • Kisqali, a targeted therapy for breast cancer, delivered approximately $3.6 billion in full-year sales (extrapolated from $902 million in Q4 with 52% year-over-year growth), reflecting robust adoption in early and metastatic breast cancer.
  • Pluvicto, a radioligand therapy for prostate cancer, generated about $1.4 billion in sales (based on $351 million in Q4 with 28% growth), though it faced some challenges in meeting analyst expectations.
  • Scemblix, a tyrosine kinase inhibitor for Philadelphia chromosome-positive chronic myeloid leukemia, received FDA accelerated approval in 2024, contributing to Novartis’ hematologic oncology portfolio.
  • Other oncology products such as Leqvio and Fabhalta also contributed to growth, with Fabhalta under priority FDA review for rare kidney disease but relevant to hematologic conditions.
Overall, Novartis’ total net sales in 2024 were approximately $50.3 billion, with oncology representing a significant and growing segment. The company reported 12% net sales growth at constant currency, driven by oncology alongside cardiovascular and immunology therapies. Novartis continues to focus on expanding its oncology pipeline and market reach, expecting mid- to high-single-digit sales growth in 2025.Thus, Novartis’ 2024 cancer sales likely approached around $5 billion to $6 billion, led by Kisqali and Pluvicto as flagship oncology products, supported by recent approvals and strong clinical adoption (24567).

Novartis planned to “optimize” the Tafinlar and Mekinist launches, "positioning Novartis as the leader in treating melanoma," it said in a statement at the time.

That, of course, was before Merck’s Keytruda and Bristol-Myers Squibb’s Opdivo came along. Both immuno-oncology drugs, now blockbusters, got their start in melanoma before moving into a slew of other indications, and their makers have worked hard to move them earlier into treatment and test them as part of combo regimens.

Since then, Gleevec copies have launched, too, taking a big chunk out of the company’s oncology sales.

That’s not to say Novartis’ cancer sales won’t be growing between now and 2024. They will, thanks in part to the company’s CAR-T therapy Kymriah, which is expected to eventually make a splash, despite early manufacturing woes. Zykadia should be making bigger top-line contributions down the line too, thanks to last year’s front-line ALK+ lung cancer approval.

Novartis is also hoping to get Kisqali going; the HR-positive, HER2-negative breast cancer drug, which competes with Pfizer’s Ibrance and Eli Lilly’s Verzenio, is off to a slower-than-expected start.

In a key approval last year, Kisqali expanded into the adjuvant treatment of certain early-stage HR-positive, HER2-negative breast cancers. The new label gives Kisqali an edge over Eli Lilly’s Verzenio by covering patients who don’t have cancer cells in their lymph nodes.

By Novartis’ projection, the broad adjuvant nod could lift Kisqali to more than $8 billion in peak sales, versus the $3.2 billion the CDK4/6 inhibitor generated in 2024 mainly from metastatic disease use.

While potential significant growth still lies ahead for Kisqali, the good days of Entresto may be numbered, as Novartis expects the heart failure combo medication will lose U.S. market exclusivity in the coming months. Besides, even if no generics entered this year, Entresto is subject to a price cut under the Inflation Reduction Act beginning in 2026.

Despite the looming Entresto patent cliff, Novartis still expects 2025 sales to grow by mid- to high-single-digit percentages.

From the Medicare Part D reforms, Novartis expects a “modest headwind,” with the biggest impact to come from coverage for the catastrophic phase for Cosentyx and Kisqali in 2025, CEO Vas Narasimhan said during the company’s fourth-quarter earnings call. As to the policies’ potential impact on Novartis’ midterm performance as outlined above, Narasimhan said he’s “very comfortable” with Novartis’ modeling, which takes “appropriately conservative assumptions.”

In two other major expansions for Novartis last year, the FDA granted accelerated approvals to Scemblix in newly diagnosed chronic myeloid leukemia and Fabhalta in the kidney disease immunoglobulin A nephropathy. For both drugs, Novartis has outlined peak sales potential at above $3 billion.

Another potential multibillion-dollar asset, radioligand therapy Pluvicto, also delivered good news for Novartis. With a favorable final overall survival analysis last year from a phase 3 trial, the FDA has in March 2025 approved the PSMA-targeted therapy for metastatic castration-resistant prostate cancer before chemotherapy.

Novartis last year beefed up its radiopharmaceuticals capabilities with the $1 billion upfront acquisition of Mariana Oncology. While Pluvicto uses lutetium as the active substance, Mariana was focused on actinium.
