Pfiz­er's CD22-tar­get­ed can­cer drug in­o­tuzum­ab wins an ac­cel­er­at­ed OK at FDA

Pfiz­er’s armed an­ti­body in­o­tuzum­ab ozogam­icin — held up as a top on­col­o­gy con­tender at the phar­ma gi­ant — has just won an ac­cel­er­at­ed ap­proval at the FDA for re­lapsed or re­frac­to­ry B-cell pre­cur­sor acute lym­phoblas­tic leukemia.

The drug is the first to reach the mar­ket which is de­signed to bind to the CD22 anti­gen on B-cells, where it then goes in­to the can­cer cell to de­liv­er a cy­to­tox­ic pay­load of calicheam­icin, de­stroy­ing the cell. Pfiz­er has made a strong push on the can­cer front in re­cent years, as wit­nessed by its rapid-fire ap­proval for its check­point in­hibitor avelum­ab, part­nered with Mer­ck KGaA, and a $14 bil­lion buy­out deal for Medi­va­tion.

In­ves­ti­ga­tors tracked a com­plete re­sponse rate of 81% for this drug — which will now be sold as Be­spon­sa — com­pared to 29% in a chemo arm. And that has some an­a­lysts pro­ject­ing peak sales of around $2 bil­lion, a sol­id hit for the phar­ma gi­ant’s on­col­o­gy di­vi­sion.

The ap­proval — com­ing af­ter the FDA of­fered a 6-month pri­or­i­ty re­view sched­ule — marks a big come­back for Pfiz­er on this drug, which flopped in a Phase III tri­al for non-Hodgkin’s lym­phoma four years ago,

Said Liz Bar­rett, glob­al pres­i­dent, Pfiz­er On­col­o­gy:

“Be­spon­sa will help ad­dress a sig­nif­i­cant need for new treat­ment op­tions in B-cell acute lym­phoblas­tic leukemia, and may help more pa­tients reach stem cell trans­plant, which pro­vides the best chance for long term re­mis­sion. We’re proud to build on our con­tin­ued com­mit­ment to pa­tients with hema­to­log­ic ma­lig­nan­cies, and will con­tin­ue our work to find new treat­ments in acute lym­phoblas­tic leukemia and oth­er blood can­cers.”

Pssst: That big Bio­haven Alzheimer's study? It was a bust. Even the sub­group analy­sis ex­ecs tout­ed was a flop

You know it’s bad when a biopharma player plucks out a subgroup analysis for a positive take — even though it was way off the statistical mark for success, like everything else.

So it was for Biohaven $BHVN on MLK Monday, as the biotech reported on the holiday that their Phase II/III Alzheimer’s study for troriluzole flunked both co-primary endpoints as well as a key biomarker analysis.

The drug — a revised version of the ALS drug riluzole designed to regulate glutamate — did not “statistically differentiate” from placebo on the Alzheimer’s Disease Assessment Scale-Cognitive Subscale 11 (ADAS-cog) and the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB).  The “hippocampal volume” assessment by MRI also failed to distinguish itself from placebo for all patients fitting the mild-to-moderate disease profile they had established for the study.

Glax­o­SmithK­line's $4B bis­pe­cif­ic can­cer drug al­liance with Mer­ck KGaA hit by big set­back with a PhI­II fail­ure on NSCLC

Close to 2 years ago, GSK’s R&D team eagerly agreed to pay up to $4 billion-plus to ally itself with Merck KGaA on a mid-stage bispecific called bintrafusp alfa, which intrigued them with the combination of a TGF-β trap with the anti-PD-L1 mechanism in one fusion protein.

But today the German pharma company says that their lead study on lung cancer was a bust, as independent monitors said there was no reason to believe that the experimental drug — targeting PD-L1/TGF-Beta — could beat Keytruda.

Bio­Med Re­al­ty snaps up in­no­va­tion cam­pus site with­in earshot of pricey and bustling Boston biotech hub

On the short list of the premier biotech hubs in the world, the Boston area has transformed into a home for innovation — and ridiculously high rent. Now, a real estate firm is seeking tenants for a major site in neighboring Somerville with more than enough elbow room.

Snapped up by BioMed Realty, the land — which consists of an existing 162,000 square-foot office building and a 7.5 acre site — will serve as an “innovation space” for a variety of research, technology and life science tenants, the real estate company said in a press release. Financial terms weren’t disclosed.

Grit­stone con­tin­ues Covid-19 push with deal to de­vel­op 'self-am­pli­fy­ing RNA' vac­cines, as shares con­tin­ue bal­loon­ing

Gritstone Oncology has had a big week, and it’s only Wednesday.

On Tuesday, the biotech revealed plans to start clinical testing of an experimental Covid-19 vaccine — in tandem with NIAID — that can also target other coronaviruses, with the goal of preventing future pandemics should SARS-CoV-2 prove difficult to cure with current vaccines. Then, on Wednesday morning, Gritstone licensed lipid nanoparticle technology from Genevant Sciences to develop what it’s calling “self-amplifying RNA vaccines” against Covid-19.

Paul Hud­son faces down French unions in fight to re­struc­ture Sanofi

Sanofi CEO Paul Hudson is facing a familiar adversary in his efforts to cut up to 1,680 jobs from the French pharma giant: French unions.

Around 200 union members staged a one-day strike Tuesday at Sanofi’s main Covid-19 vaccine plant in Marcy-l’Étoile to protest the cuts, The Associated Press reported, with other members joining at other facilities across the country.

France’s finance minister Bruno Le Maire, meanwhile, went on French radio twice this week to talk about the company. On Monday, per Reuters, he told RTL that Sanofi would not close any plants or lay off any employees in the restructuring. But on Wednesday morning, he re-emerged on BFM and said he would like three things from the drugmaker, including confirmation that there will be no site closures and layoffs.

Poll: Should Joshua Sharf­stein or Janet Wood­cock lead the FDA from here?

It’s time for a new FDA commissioner to come on board, a rite of passage for Joe Biden’s administration that should help seal the new president’s rep on seeking out the experts to lead the government over the next 4 years.

As of now, the competition for the top job appears to have narrowed down to 2 people: The longtime CDER chief Janet Woodcock and Joshua Sharfstein, the former principal deputy at the FDA under Peggy Hamburg. Both were appointed by Barack Obama.

Bris­tol My­ers Squibb gets re­view date for Op­di­vo com­bo in gas­tric can­cer, look­ing to over­turn Keytru­da's 3-year lead

The past two months have been tough for Bristol Myers Squibb and its checkpoint inhibitor Opdivo after setbacks in lung and brain cancers. But in the battle against Merck’s Keytruda, any success matters — and now Bristol could be looking at a quick approval for Opdivo in an unmatched indication.

The FDA will launch a speedy review of a combination of Bristol Myers Squibb’s Opdivo and chemotherapy to treat first-line patients with advanced or metastatic gastric cancer, gastroesophageal junction cancer or esophageal adenocarcinoma, the drugmaker said Wednesday. The agency set an action date of May 25 for the application.

Covid-19 claims an­oth­er PDU­FA vic­tim as Glax­o­SmithK­line push­es back planned PD-1 roll­out

Bristol Myers Squibb isn’t the only pharma giant that’s been standing in the FDA’s waiting line for site inspections.

GlaxoSmithKline is telling us today that their H2 2020 PDUFA deadline for the PD-1 drug dostarlimab — picked up in its Tesaro buyout — was pushed back due to a delay in the manufacturing site inspection needed for a regulatory decision. And that is forcing the company to revise its timeline.
