Pfizer is enlisting another Flagship startup to help it create new obesity medicines.
After June’s
ProFound Therapeutics tie-up
, Pfizer will work with the incubator’s Ampersand Biomedicines in the hunt for new biologics for obesity.
The New York pharmaceutical company is also tapping into Flagship-founded Montai Therapeutics to find new small molecules for potentially treating lung cancer, the companies said Wednesday morning.
The two pacts are part of
Pfizer’s broader alliance
with the Cambridge, MA-based Flagship, which recently reeled in about
$3.6 billion in new funds
as pharma partnerships become a “
bigger and bigger deal
.”
Pfizer has had an uneven few years in obesity, particularly with
its danuglipron program
. Last month, it revealed
more details
about its other early-stage bets: a GIP antagonist and a once-daily oral GLP-1.
Ampersand hopes to help Pfizer create obesity treatments that go to a specific site in the body, rather than hitting healthy tissues or cells, so as to avoid side effects — like muscle loss and gastrointestinal concerns — and to make the drugs more potent.
The startup, which
emerged with $50 million
in March 2023, uses computational methods to find “addresses” for drugs to go to and then creates an “actuator” to carry out the therapeutic function, Flagship general partner Avak Kahvejian told
Endpoints News
last year. In January, it
bought
antibody discovery tech startup AbCheck, an Affimed subsidiary, for $6 million.
“We have addresses in virtually every tissue in the body, so you could think about virtually any disease,” CEO
Jason Gardner
said in an interview. Ampersand will likely make multiple other industry collaborations, he said, and it could form more tie-ups around obesity.
It’s early days with the Pfizer partnership, and Gardner declined to disclose the specific pathway tissue that they’re looking at. Flagship’s work in obesity has also attracted the attention of Novo Nordisk. Its companies
Metaphore Biotechnologies
and
Omega Therapeutics
have both formed partnerships with the Danish drugmaker.
In cancer, Pfizer’s new partnership with Montai will look at mechanisms that lead to lung cancer cell growth and find new small molecules that can potentially be turned into therapies. Pfizer has made oncology a core focus following its $43 billion Seagen acquisition last year.
Montai emerged with
$50 million in December 2022
and a high-profile CEO, Margo Georgiadis, who previously led Google’s Americas division and steered Ancestry.com to a nearly $5 billion
exit
to Blackstone.
The startup scours through molecules already consumed by humans via foods, supplements and herbal medicines. Its computational tools have brought together nearly 200 million so-called “Anthromolecules” and their derivatives, Georgiadis said. The company’s name means “climbing mountains with AI,” she said.
Georgiadis said in an interview that the company is trying to “create the first machine learning that enables us to decode that language of chemistry and how it connects to our biology.”
“By doing that, it enables us to take advantage of this unbelievably rich and diverse chemistry set that pharma had kind of put to the side,” she said. “It’s how drug development started. It’s a super-proven source of drugs, but it was perceived as complex, hard to make, the challenges with polypharmacology.”
Montai was working on a small molecule agonist for an undisclosed pathway in inflammation and immunology when Pfizer realized an antagonist of that pathway could be applied in lung cancer, Georgiadis said. The 65-employee company has created an internal pipeline of nine I&I therapies that are transcription factors and biologic replacements in dermatology, gastrointestinal and respiratory diseases, she said.
The company is “developing partnerships” with more companies, Georgiadis said, as Montai’s work applies across immunology, oncology, neuro-inflammation and other areas.
