And then there were two: Janssen bows out of Hori­zon takeover ne­go­ti­a­tions

Horizon Therapeutics announced last week that it was in talks with three pharmaceutical giants that could take over the company. You can now remove one of them from the equation.

J&J’s Janssen, after Horizon reported its initial involvement in early discussions to acquire the rare disease biotech, issued a statement Saturday that said Janssen “does not intend to make an offer for Horizon,” and that Janssen is bound by restrictions set in Rule 2.8 of the Irish Takeover Rules. These rules are in place for any company interested in taking over Irish companies, with Horizon Therapeutics currently based in Dublin.

Pfiz­er lays off em­ploy­ees at Cal­i­for­nia and Con­necti­cut sites

Pfizer has laid off employees at its La Jolla, CA, and Groton, CT sites, according to multiple LinkedIn posts from former employees.

The Big Pharma confirmed to Endpoints News it has let go of some employees, but a spokesperson declined to specify how many workers were impacted and the exact locations affected. Earlier this month, the drug developer had confirmed to Endpoints it was sharpening its focus and doing away with some early research on areas such as rare disease, oncology and gene therapies.

Lil­ly en­ters ripe BTK field with quick FDA nod in man­tle cell lym­phoma

Eli Lilly has succeeded in its attempt to get the first non-covalent version of Bruton’s tyrosine kinase, or BTK, inhibitors to market, pushing it past rival Merck.

The FDA gave an accelerated nod to Lilly’s daily oral med, to be sold as Jaypirca, for patients with relapsed or refractory mantle cell lymphoma.

The agency’s green light, disclosed by the Indianapolis Big Pharma on Friday afternoon, catapults Lilly into a field dominated by covalent BTK inhibitors, which includes AbbVie and Johnson & Johnson’s Imbruvica, AstraZeneca’s Calquence and BeiGene’s Brukinsa.

No­vavax gets ready to take an­oth­er shot at Covid vac­cine mar­ket with next sea­son plans

While mRNA took center stage at yesterday’s FDA vaccine advisory committee meeting, Novavax announced its plans to deliver an updated protein-based vaccine based on new guidance.

Vaccines and Related Biological Products Advisory Committee (VRBPAC) members voted unanimously in favor of “harmonizing” Covid vaccine compositions, meaning all future vaccine recipients would receive a bivalent vaccine, regardless of whether they’ve gotten their primary series.

F-star gets down to the wire with $161M sale to Chi­nese buy­er as na­tion­al se­cu­ri­ty con­cerns linger

With the clock ticking on F-star Therapeutics’ takeover by a Chinese buyer, the companies are still scrambling to remove a hold on the deal from the US government’s Committee on Foreign Investment in the United States.

F-star and invoX Pharma said they are “actively negotiating” with CFIUS “about the terms of a mitigation agreement to address CFIUS’s concerns regarding potential national security risks posed by the transaction.”

FDA ad­vi­so­ry com­mit­tee votes unan­i­mous­ly in fa­vor of bi­va­lent Covid shots re­plac­ing pri­ma­ry se­ries

The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) voted unanimously in favor of “harmonizing” Covid vaccine compositions, meaning all current vaccine recipients would receive a bivalent vaccine, regardless of whether they’ve gotten their primary series.

The vote marks an effort to clear up confusion around varying formulations and dosing schedules for current primary series and booster vaccines, as well as “get closer to the strains that are circulating,” according to committee member Paul Offit, professor of pediatrics at the Children’s Hospital of Philadelphia.

FDA re­ports ini­tial 'no sig­nal' for stroke risk with Pfiz­er boost­ers, launch­es con­comi­tant flu shot study

The FDA hasn’t detected any potential safety signals, including for stroke, in people aged 65 years and older who have received Pfizer’s bivalent Covid booster, one senior official told members of the agency’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) on Thursday.

The update comes as the FDA and CDC investigate a “preliminary signal” that may indicate an increased risk of ischemic stroke in older Americans who received Pfizer’s updated shot.

FDA cuts off use for As­traZeneca’s Covid-19 ther­a­py Evusheld

The FDA has stopped use of another drug as a result of the new coronavirus variants. On Thursday, the agency announced that AstraZeneca’s antibody combo Evusheld, which was an important prevention option for many immunocompromised people and others, is no longer authorized.

The FDA said it made its decision based on the fact that Evusheld works on fewer than 10% of circulating variants.

Evusheld was initially given emergency authorization at the end of 2021. However, as Omicron emerged, so did studies that showed Evusheld might not work against the dominant Omicron strain. In October, the FDA warned healthcare providers that Evusheld was useless against the Omicron subvariant BA.4.6. It followed that up with another announcement earlier this month that it did not think Evusheld would work against the latest Omicron subvariant XBB.1.5.
