New patent on the prime edit­ing of DNA award­ed to Broad In­sti­tute's David Liu

The genome editing revolution will be patented. Or at least that’s the case for this latest US patent, awarded Tuesday to the Broad Institute’s David Liu and team for the compositions and methods behind the prime editing of a target DNA molecule (e.g., a genome) that enables a nucleotide change and/or targeted gene mutation, according to the abstract.

Developed in Liu’s lab at the Broad Institute, which famously defeated Jennifer Doudna and UC Berkeley in court over CRISPR-related patents, the idea behind prime editing — dubbed CRISPR 3.0 — was published in Nature in December 2019, and that spawned a startup known as Prime Medicine.

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.

Four years in, Sana gets first FDA go-ahead to bring can­cer treat­ment in­to the clin­ic

Sana Biotechnology is finally headed to the clinic.

Thursday afternoon, the biotech announced the FDA had cleared its application to start a clinical trial for its allogeneic, or “off-the-shelf,” CAR-T cell therapy targeting the antigen CD19 for patients with B-cell lymphomas and leukemias. Sana said its therapy, dubbed SC291, was designed to evade the immune system, which could help cell therapy produce a more durable response in patients, a concern that has followed such off-the-shelf therapies that use donor cells as opposed to a patient’s own cells.

J&J, Leg­end say Carvyk­ti beat stan­dard ther­a­py in ear­li­er-line blood can­cer

J&J and Legend Biotech’s next step in turning their CAR-T therapy Carvykti into a potential megablockbuster has succeeded, the companies said Friday.

Carvykti achieved the primary endpoint — progression-free survival — in an open-label Phase III study testing the treatment in second- to fourth-line multiple myeloma patients. The CARTITUDE-4 trial, for which there aren’t any hard data yet, represents the biggest development for Carvykti’s ability to compete with Bristol Myers Squibb’s Abecma since its approval last February.

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.

Bris­tol My­ers, Charles Riv­er join Se­ries A fund­ing for iVex­Sol

Massachusetts-based iVexSol has secured funding to the tune of $23.8 million in its latest Series A round. The new investors include Bristol Myers Squibb, manufacturer Charles River Laboratories and Asahi Kasei Medical.

iVexSol is a manufacturer of lentiviral vectors (LVV), used in making gene therapies, and this latest round of fundraising brings its total Series A total over $39 million, which will be used to recruit more employees and bolster its technology.
