Roche dumps its PhI­II PI3K ef­fort on taselis­ib af­ter re­searchers track poor sur­vival edge, harsh side ef­fects for breast can­cer

CHICA­GO — You can write off an­oth­er PI3K drug.

Roche has de­cid­ed to scrap its con­tender taselis­ib af­ter in­ves­ti­ga­tors re­port­ed a slight, 2-month pro­gres­sion-free sur­vival ad­van­tage for the drug — along with a sketchy safe­ty pro­file com­mon to the class — com­bined with ful­ves­trant hor­mone ther­a­py in a Phase III study of metasta­t­ic breast can­cer.

Here’s what Roche had to say:

The mag­ni­tude of ben­e­fit ob­served in SAND­PIPER isn’t as strong as we had hoped for and, giv­en the chal­leng­ing safe­ty pro­file of this com­bi­na­tion and the cur­rent clin­i­cal land­scape, we will not be pur­su­ing an FDA sub­mis­sion for taselis­ib based on the da­ta pre­sent­ed at AS­CO.

José Basel­ga

Jose Basel­ga han­dled the AS­CO pre­sen­ta­tion, out­lin­ing the slight edge on PFS against a slate of grade 3 or high­er cas­es of di­ar­rhea (12%), hy­per­glycemia (10%), col­i­tis (3%), and stom­ati­tis (2%). The ad­verse events trig­gered a high rate of dis­con­tin­u­a­tions for the drug com­bo — 17% ver­sus 2% — and dose re­duc­tions for more than a third of the pa­tients in the taselis­ib arm.

An­a­lysts have been shak­ing their heads over the PI3K field for years. Gilead’s pi­o­neer­ing Zy­delig got slapped with a black box warn­ing on side ef­fects, forc­ing an end to its quest to com­plete front­line tri­als. Bay­er’s Aliqopa (co­pan­lis­ib) was ap­proved last fall for fol­lic­u­lar lym­phoma pa­tients on the ba­sis of some promis­ing re­sults, crowd­ing a field that Ve­rastem hopes to join with du­velis­ib, a PI3K dropped by In­fin­i­ty Phar­ma­ceu­ti­cals af­ter Ab­b­Vie walked away af­ter get­ting a glimpse of unim­pres­sive — but still ap­prov­able — re­sults.

The po­ten­tial here, though, is still at­tract­ing de­vel­op­ers like MEI Phar­ma, which re­cent­ly raised $75 mil­lion for their reg­is­tra­tion study. And Roche hasn’t giv­en up on the tar­get. The phar­ma gi­ant notes:

Still, HR-pos­i­tive, HER2-neg­a­tive MBC re­mains in­cur­able and we are in­ves­ti­gat­ing new med­i­cines for it, in­clud­ing oth­er mol­e­cules that tar­get PI3K, that we hope could pro­vide more ro­bust ef­fi­ca­cy and bet­ter tol­er­a­bil­i­ty. We re­main com­mit­ted to find­ing new ways to tar­get breast can­cer to help im­prove out­comes for peo­ple with many dif­fer­ent types of the dis­ease.

Health­care Dis­par­i­ties and Sick­le Cell Dis­ease

In the complicated U.S. healthcare system, navigating a serious illness such as cancer or heart disease can be remarkably challenging for patients and caregivers. When that illness is classified as a rare disease, those challenges can become even more acute. And when that rare disease occurs in a population that experiences health disparities, such as people with sickle cell disease (SCD) who are primarily Black and Latino, challenges can become almost insurmountable.

The End­points 11: They've got mad mon­ey and huge am­bi­tions. It's time to go big or go home

These days, selecting a group of private biotechs for the Endpoints 11 spotlight begins with a sprint to get ahead of IPOs and the M&A teams at Big Pharma. I’ve had a couple of faceplants earlier this year, watching some of the biotechs on my short list choose a quick leap onto Nasdaq or into the arms of a buyer.

Vividion, you would have been a great pick for the Endpoints 11. I’m sorry I missed you.

Dave Lennon, former president of Novartis Gene Therapies

So what hap­pened with No­var­tis Gene Ther­a­pies? Here's your an­swer

Over the last couple of days it’s become clear that the gene therapy division at Novartis has quietly undergone a major reorganization. We learned on Monday that Dave Lennon, who had pursued a high-profile role as president of the unit with 1,500 people, had left the pharma giant to take over as CEO of a startup.

Like a lot of the majors, Novartis is an open highway for head hunters, or anyone looking to staff a startup. So that was news but not completely unexpected.

Who are the women su­per­charg­ing bio­phar­ma R&D? Nom­i­nate them for this year's spe­cial re­port

The biotech industry has faced repeated calls to diversify its workforce — and in the last year, those calls got a lot louder. Though women account for just under half of all biotech employees around the world, they occupy very few places in C-suites, and even fewer make it to the helm.

Some companies are listening, according to a recent BIO survey which showed that this year’s companies were 2.5 times more likely to have a diversity and inclusion program compared to last year’s sample. But we still have a long way to go. Women represent just 31% of biotech executives, BIO reported. And those numbers are even more stark for women of color.

FDA au­tho­rizes Pfiz­er's vac­cine boost­er for se­niors, those at high risk for se­vere Covid-19

The Biden administration’s goal of kicking off its booster shot drive for the entire US population this week is not quite going as planned.

First, Pfizer applied for approval of a supplemental application for the booster shots, but since last Friday’s adcomm reviewing them, the plan has devolved into an EUA, which the FDA issued late Thursday evening.

The population that is now eligible for the booster, six months after receiving the first pair of Pfizer-BioNTech vaccines, also narrowed from what Pfizer applied for (everyone who’s eligible for the initial Pfizer shots) to just those who are 65 or older, or at high-risk of a Covid infection, including health care workers and others with occupational hazards.

Fi­nal analy­sis of US-fund­ed Mod­er­na Covid vac­cine tri­al shows 98% ef­fi­ca­cy against se­vere dis­ease

A final look at the results of the placebo-controlled Moderna trial in the New England Journal of Medicine, published Thursday afternoon, shows how the vaccine continues to prevent Covid-19 and severe cases after more than five months following the second shot.

Of the more than 30,000 enrolled in the trial that ultimately led to the vaccine’s EUA, only two people in the vaccine group got a severe form of the disease, compared to 106 in the placebo group — leading to an efficacy of 98%.

The fire un­der Glax­o­SmithK­line's Em­ma Walm­s­ley grows as an­oth­er well-known ac­tivist in­vestor grabs its pitch­fork — re­port

Bluebell Capital Partners, a proxy brawler fresh off a campaign to oust global food giant Danone’s CEO and most of its board of directors, has bought a stake in UK drugmaker GlaxoSmithKline with its eyes trained directly on Emma Walmsley, the Financial Times reported Wednesday.

The London-based hedge fund joins another notorious activist firm in Paul Singer’s Elliott Management, which earlier this year called for a shakeup in leadership at GSK to handle what the company described as a wealth of riches across the drug giant’s portfolio hindered by limited vision from top staff.

FDA+ roundup: Bs­U­FA III ready for show­time, court tells FDA to re-work com­pound­ing plan, new guid­ance up­dates and more

The FDA has now spelled out what exactly will be included in the third iteration of Biosimilar User Fee Act (BsUFA) from 2023 through 2027, which similarly to the prescription drug deal, sets fees that industry has to pay for submitting applications, in exchange for firm timelines that the agency must meet.

This latest deal includes several sweeteners for the biosimilar industry, which has yet to make great strides in the US market, with shorter review timelines for safety labeling updates and updates to add or remove an indication that does not contain efficacy data.

Clover Biopharmaceuticals announced Wednesday that its vaccine candidate showed 79% efficacy against the Delta variant in a Phase II/III trial dubbed Spectra, and 67% effective against Covid-19 overall.
