“Together, Pfizer and Seagen seek to accelerate the next generation of cancer breakthroughs and bring new solutions to patients by combining the power of Seagen’s antibody-drug conjugate (ADC) technology with the scale and strength of Pfizer’s capabilities and expertise,” Pfizer Chairman and CEO Dr. Albert Bourla said in a statement.

Seagen Inc., headquartered in Bothell, Washington, is a biotech company that focuses on drug development. Its primary products utilise monoclonal antibodies that attach to the surface of cancer cells and transport a cancer-fighting agent, while preserving nearby healthy tissue.

Monoclonal antibodies are lab-made proteins delivered mostly by IV at an infusion center, according to the Cleveland Clinic.

Seagen’s top seller, Adcetris, treats lymph system cancers. It brought in USD 839 million in sales last year, a 19 percent increase over the previous year.

Aside from Adcetris, Seagen also has a deal with Pfizer’s Array BioPharma to develop, make and sell the breast and colorectal cancer treatment Tukysa. It brought in USD 353 million in sales last year.

Seagen also saw sales grow 33 percent to USD 451 million last year for Padcev, which treats some cancers of the urinary tract, including the bladder. The drugmaker is developing and selling that treatment with Astellas Pharma Inc.

Seagen anticipates generating approximately USD 2.2 billion of revenue this year, representing 12 percent year-over-year growth, from its four in-line medicines, royalties and collaboration and license agreements.

Pfizer believes Seagen could contribute more than USD 10 billion in risk-adjusted revenues in 2030, with potential significant growth beyond 2030.

Seagen, which changed its name from Seattle Genetics in 2020, shaved its loss to USD 610 million last year. That’s down from USD 674 million in 2021. Total revenue grew about 25 percent last year to nearly USD 2 billion.

The company named former Novartis executive David Epstein CEO in November. Long-time CEO and co-founder Clay Siegall resigned last spring.

Cancer treatments are one of Pfizer’s main businesses. That portfolio of drugs includes the breast cancer treatment Ibrance, which brought in nearly USD 1.3 billion in sales last year.

Pfizer recorded about USD 100 billion in total revenue last year and has been flush with cash thanks to sales of its COVID-19 vaccine and treatment, Comirnaty and Paxlovid.

CEO Albert Bourla said earlier this year that the company planned to use its “extraordinary firepower” to buy products that will deliver USD 25 billion in incremental revenue by 2030.

New York-based Pfizer Inc. has already spent USD 11.6 billion on migraine treatment developer Biohaven Pharmaceutical.

It also spent USD 5.4 billion on sickle cell disease treatment maker Global Blood Therapeutics and bought Arena Pharmaceuticals for another USD 6.7 billion.

Bourla said in January that Pfizer plans to launch 19 new products or new indications for existing products over the next year and a half.

The drugmaker needs more revenue sources in part because it faces the expiration of patents protecting drugs like Ibrance from cheaper competition in the coming years.

Both companies’ boards have unanimously approved the deal. The companies expect to complete the transaction in late 2023 or early 2024. It still needs approval from Seagen’s stockholders.
