Pfizer is betting big on cancer drugs after Covid decline

Pfizer is able to transfer on from Covid. 

Now, the corporate is betting on most cancers medicine to assist it regain its footing after a rocky yr marked by the fast decline of its Covid enterprise. It simply may take some time earlier than that wager pays off. 

Pfizer pitched its deeper push into oncology throughout a four-hour investor occasion final week. And it had a splashy 60-second Tremendous Bowl advert that touted its initiative to “outdo most cancers.” 

The shift comes at a vital time for Pfizer. The pharmaceutical big has been attempting to shore up investor sentiment after its shares fell greater than 40% in 2023. That share drop erased greater than $100 billion in Pfizer’s market worth.

Together with plummeting demand for its Covid merchandise, Pfizer dissatisfied Wall Road final yr with the underwhelming launch of a brand new RSV shot, a twice-daily weight reduction tablet that fell brief in scientific trials and a 2024 forecast that missed expectations. The corporate has launched a $4 billion cost-cutting program, shedding tons of of workers and shaving down its analysis and improvement spending. 

In the course of the investor day, Pfizer laid out its priorities now that it has absolutely built-in with the focused most cancers drugmaker Seagen. That $43 billion Seagen acquisition doubled Pfizer’s oncology drug pipeline to 60 completely different experimental applications. 

With Seagen below its belt, Pfizer says its drug pipeline might produce a minimum of eight blockbuster medicines by 2030, up from simply 5 immediately. However the firm didn’t disclose which medicine it believes might provide that potential. 

Some analysts famous that it’d take a couple of years for a few of Pfizer’s most cancers medicine in mid-stage improvement to point out pivotal scientific trial knowledge and turn out to be much less dangerous. 

Pfizer’s present oncology portfolio can be going through some aggressive stress. Income from the blockbuster breast most cancers drug Ibrance and prostate most cancers remedy Xtandi, which Pfizer shares with Astellas Pharma, has declined over the previous yr. Each medicine are anticipated to lose market exclusivity in 2027. 

Nonetheless, some analysts got here out of the investor day feeling inspired. 

“The corporate is going through plenty of challenges, however we imagine the occasion was successful in laying out a path for the oncology enterprise to assist offset upcoming patent losses, and drive progress sooner or later,” Guggenheim analysts wrote in a observe Tuesday. 

Pfizer used the investor occasion to formally introduce its new enterprise division devoted to most cancers analysis and to put out a long-term technique for it via the top of the last decade.

That oncology unit hosts a sprawling portfolio of experimental medicines that Pfizer and Seagen found or acquired via offers, in addition to the remedies each firms have lengthy been promoting. 

The unit is led by Chris Boshoff, a longtime Pfizer government who most just lately served as the corporate’s head of most cancers analysis and improvement. 

“As a newly mixed group, our experience and collective capabilities at the moment are amplified to ship much more influence for sufferers than every firm might do by itself,” Boshoff mentioned final week to kick off the occasion.  

Boshoff highlighted the size of Pfizer’s capabilities, noting it has 10 manufacturing websites producing most cancers medicine on three continents, whereas Seagen had only one. He additionally pointed to Pfizer’s industrial presence in additional than 100 international locations and a customer-facing industrial staff that’s triple the dimensions of Seagen’s. 

Pfizer didn’t present a selected gross sales projection for its oncology franchise by 2030. However the firm mentioned it expects roughly two-thirds of risk-adjusted oncology income to return from new medicine and new indications — or remedy makes use of — for present merchandise by the top of the last decade.

Pfizer reiterated its expectation that the Seagen acquisition will usher in $10 billion in gross sales by 2030. 

However the firm supplied little steerage on what Seagen’s progress will appear to be till the top of the last decade, UBS analyst Trung Huynh mentioned in a observe Thursday. 

Pfizer additionally highlighted an enormous shift in its drug pipeline technique. 

Boshoff mentioned the oncology division plans to shift to biologic medicine as its major income, growing the proportion of these remedies in its pipeline from 6% to 65% by 2030.

Biologics are remedies derived from residing sources corresponding to animals or people, together with vaccines, stem cell remedies and gene therapies. They’re among the many costliest prescribed drugs within the U.S.

Earlier than the Seagen deal, 94% of Pfizer’s most cancers merchandise had been small-molecule medicine. These medicines are made from chemical substances and have low molecular weights. 

Boshoff mentioned biologics characterize “a extra sturdy income potential” based mostly on a number of components. That features upcoming patent expirations and potential stress from President Joe Biden’s Inflation Discount Act. 

A provision of that legislation permits Medicare to begin negotiating the costs of biologics as early as 13 years after they obtain Meals and Drug Administration approval, in contrast with simply 9 years for small-molecule medicine. The pharmaceutical business has argued that might deter drugmakers from investing in small molecules.

Pfizer’s resolution to rely extra on biologics can also provide “higher safety” towards competitors from cheaper copycats, Guggenheim analysts mentioned of their observe. These copycats, or biosimilars, have traditionally had bother gaining market share from biologic remedies. That is in contrast to with medicine known as generics, that are actual copies of small-molecule remedies. 

Small molecules will stay considered one of three core drug varieties of Pfizer’s oncology division. The opposite two are biologics, particularly bispecific antibodies, and antibody-drug conjugates, or ADCs. 

Notably, the corporate is growing a “next-generation” platform for ADCs that mixes Pfizer’s protein engineering and antibody design capabilities with Seagen’s ADC know-how. Collectively, the businesses have 12 ADCs in improvement, six of that are in early scientific trials or research on animals.

JPMorgan analyst Chris Schott wrote in a observe final week that the agency walked away from the investor occasion inspired by the breadth of Pfizer’s mid-stage oncology pipeline. However he famous that it’s going to take time earlier than plenty of the remedies present “pivotal knowledge.”

Pfizer plans to concentrate on 4 major varieties of most cancers: breast most cancers; genitourinary most cancers, which impacts urinary and genital organs or capabilities; thoracic most cancers, corresponding to lung, head and neck most cancers; and hematology-oncology, or cancers of the blood, corresponding to a number of myeloma and lymphomas. 

Pfizer expects breast most cancers’s contribution to complete oncology gross sales to drop to about 10% by 2030 from roughly 40% final yr, the corporate’s oncology industrial chief Suneet Varma mentioned throughout the occasion. 

That decline accounts for the upcoming lack of exclusivity of top-seller Ibrance, which raked in $4.75 billion in gross sales in 2023. 

However the firm mentioned it has a handful of breast most cancers medicine in improvement that would turn out to be “potential progress drivers” as Ibrance gross sales fall. That features a sure kind of remedy known as atirmociclib that would doubtlessly be more practical and simpler for sufferers to tolerate. 

Pfizer is testing the medication as a second-line remedy for a sure kind of breast most cancers in a section three trial. A second-line remedy is given when an preliminary remedy would not work or stops working. 

The corporate additionally plans to begin a separate late-stage trial on atirmociclib as a primary remedy for a similar situation within the second half of the yr.

Pfizer expects genitourinary most cancers to make up an estimated 35% of oncology gross sales by 2030, which might make it the biggest franchise of the most cancers enterprise. That is up from 20% in 2023. 

Pfizer is testing an experimental ADC known as disitamab vedotin — which Seagen licensed from Chinese language agency RemeGe — as a remedy for sure bladder cancers, with knowledge from mid-stage and late-stage trials anticipated in 2025 and 2026.

Notably, RemeGe already sells that drug in China. Pfizer can be inspecting the medication’s potential to deal with breast most cancers and different tumor varieties.

In the meantime, Padcev, an ADC Pfizer shares with Astellas Pharma, together with Merck‘s immunotherapy Keytruda is changing into a brand new first-line normal of look after bladder most cancers. Pfizer executives final week mentioned Padcev had “mega-blockbuster” potential, which the corporate defines as raking in annual gross sales of greater than $3 billion. 

Pfizer executives anticipate thoracic most cancers to double its income contributions by 2030. 

Seagen brings an ADC known as sigvotatug vedotin to this franchise. The drug just lately entered a late-stage trial as a second-line remedy for a sure kind of lung most cancers, with knowledge anticipated round 2026 to 2027. Pfizer additionally plans to check the ADC as a first-line remedy.

Guggenheim analysts mentioned they anticipate the remedy to be considered one of Pfizer’s blockbuster oncology medicine by the top of the last decade. These analysts additionally anticipate a bispecific drug known as Elrexfio, which falls below Pfizer’s hematology-oncology portfolio, to ultimately turn out to be a prime vendor.

The hematology-oncology franchise is anticipated to account for 25% of the most cancers unit’s gross sales by 2030, up from simply 10% in 2023. 

The FDA has accredited Elrexfio for sufferers with a number of myeloma who’ve tried a minimum of 4 prior varieties of remedy. However Pfizer is conducting two late-stage scientific trials on Elrexfio as a second-line remedy, with knowledge not anticipated till round 2025 and 2026. 

Pfizer is splitting the remainder of its enterprise outdoors of oncology into two divisions: a U.S. industrial unit and a world industrial unit. These divisions are specializing in vaccines, together with metabolic and inflammatory circumstances. 

This fall, Pfizer plans to roll out one other up to date model of its Covid vaccine that can goal a brand new pressure of the virus. 

The corporate beforehand outlined plans to develop “next-generation” variations of its Covid shot, which intention to broaden and prolong the safety individuals get to a full yr. 

However Pfizer hasn’t determined whether or not to maneuver ahead with these plans as a result of the corporate must be satisfied that there’s nonetheless an “eagerness to embrace Covid intervention,” Dr. Mikael Dolsten, the corporate’s chief scientific officer, informed CNBC in an interview final week.

Dolsten pointed to 2 different “sturdy pillars” within the firm’s vaccine portfolio: bacterial and viral photographs. The corporate is testing a “fourth-generation” model of its vaccine to forestall pneumococcal illness, which is brought on by a micro organism that may assault completely different components of the physique.

Pfizer can be working to increase the usage of its shot towards respiratory syncytial virus, generally known as RSV, to high-risk sufferers ages 18 to 59. It is at present accredited within the U.S. for expectant moms and adults age 60 and above. 

The corporate can be testing mixture vaccines focusing on a number of respiratory viruses, together with a shot for Covid and the flu in late-stage improvement.

Outdoors of vaccines, the corporate is growing an oral remedy for sickle cell illness known as GBT601. Pfizer views that drug as a doubtlessly more practical successor to its drug Oxbryta, which is already accredited for the situation.

Pfizer additionally expects to launch mid-stage trial knowledge on its experimental remedy for most cancers cachexia, or what Dolsten known as “the alternative of weight problems.” It refers back to the lack of physique weight and muscle mass, together with weak point which will happen in sufferers with most cancers, AIDS or different continual ailments.

One other space that is prime of thoughts for traders is weight problems. Pfizer expects to launch early-stage trial knowledge on a once-daily model of its experimental weight reduction tablet, danuglipron, within the first half of the yr. The corporate can be engaged on a second drug for weight problems, however has not disclosed the way it will work. 

Dolsten touted the potential of a weight-loss drug tablet, which might assist meet the hovering demand for weight problems remedies. A lot of the prevailing injectable medicine for the situation are in scarcity within the U.S. He additionally famous {that a} tablet would possible be priced otherwise than injections, which value round $1,000 per thirty days earlier than insurance coverage. 

“A tablet would permit you additionally to have extra entry,” Dolsten mentioned. “When you’ve got 300 million sufferers per yr, it will likely be one of many greatest drugs ever.”
