Pi­lot project pro­vides a snap­shot of ef­fec­tive­ness of Pfiz­er’s PARP con­tender ta­la­zoparib

Jen­nifer Lit­ton, MD An­der­son Can­cer Cen­ter

You can ex­pect some no­table re­search up­dates on the slate of late-stage PARP in­hibitors at this week­end’s an­nu­al Eu­ro­pean So­ci­ety of Med­ical On­col­o­gy meet­ing. And an ear­ly teas­er on what’s to come at ES­MO should help whet every­one’s ap­petite for more.

Jen­nifer Lit­ton, the prin­ci­pal in­ves­ti­ga­tor in the Phase III ta­la­zoparib study and an in­ves­ti­ga­tor at MD An­der­son Can­cer Cen­ter, set up a small pi­lot study that used the PARP in­hibitor on a group of 13 breast can­cer pa­tients with BR­CA mu­ta­tions.

These pa­tients were giv­en the drug ahead of pre-sur­gi­cal chemo, and Lit­ton says her group tracked an av­er­age 78% tu­mor shrink­age among the women in the study. The full range ex­tend­ed from 30% to 98%.

“Ac­knowl­edg­ing that this is a small study, I can’t think of any sys­temic ther­a­py that gives re­sults this con­sis­tent­ly strong in on­ly two months,” Lit­ton said. A few weeks ago, Lit­ton start­ed an ex­ten­sion of the pi­lot, en­rolling the first 6 of 20 pa­tients who can shed fur­ther light on the drug’s use in treat­ing breast can­cer. And her group is us­ing back­ing from MD An­der­son’s Moon Shots pro­gram for the work, look­ing to quick­ly ad­vance new ther­a­pies for can­cer.

“If this study pro­duces sim­i­lar­ly strong re­sults, the next step would be to di­rect­ly com­pare ta­la­zoparib to chemother­a­py in the pre-sur­gi­cal, cu­ra­tive set­ting,” Lit­ton added, “We might be able to de­lay or re­place chemother­a­py if we can get sim­i­lar ef­fi­ca­cy with less tox­i­c­i­ty from treat­ment.”

That’s an in­trigu­ing piece of the puz­zle for Pfiz­er $PFE, which agreed to pay $14 bil­lion for Medi­va­tion to get its hands on Xtan­di as well as the late-stage PARP drug. These drugs work by block­ing a DNA re­pair path­way and there has been a con­sid­er­able amount of re­search demon­strat­ing their ef­fec­tive­ness as well as a rel­a­tive­ly good safe­ty pro­file.

The big show this week­end, though, will be re­served for Tesaro $TSRO and Clo­vis On­col­o­gy $CLVS, which both have close­ly-watched PARPs lin­ing up for po­ten­tial ap­provals. For Clo­vis, ru­ca­parib presents its first re­al op­por­tu­ni­ty to gain a cru­cial­ly im­por­tant FDA ap­proval. And Tesaro has been fu­el­ing high hopes with its own late-stage da­ta set. Share prices on both com­pa­nies have been soar­ing over the last few months.

We’ll keep you post­ed on the re­sults.

As­traZeneca trum­pets the 'mo­men­tous' da­ta they found for Tagris­so in an ad­ju­vant set­ting for NSCLC — but many of the ex­perts aren’t cheer­ing along

AstraZeneca is rolling out the big guns this evening to provide a salute to their ADAURA data on Tagrisso at ASCO.

Cancer R&D chief José Baselga calls the disease-free survival data for their drug in an adjuvant setting of early stage, epidermal growth factor receptor-mutated NSCLC patients following surgery “momentous.” Roy Herbst, the principal investigator out of Yale, calls it “transformative.”

Ab­b­Vie wins an ap­proval in uter­ine fi­broid-as­so­ci­at­ed heavy bleed­ing. Are ri­vals My­ovant and Ob­sE­va far be­hind?

Women expel on average about 2 to 3 tablespoons of blood during their time of the month. But with uterine fibroids, heavy bleeding is typical — a third of a cup or more. Drugmakers have been working on oral therapies to try and stem the flow, and as expected, AbbVie and their partners at Neurocrine Biosciences are the first to make it across the finish line.

Known chemically as elagolix, the drug is already approved as a treatment for endometriosis under the brand name Orilissa. It targets the GnRH receptor to decrease the production of estrogen and progesterone.

Cap­i­tal­iz­ing Pablo: The world’s biggest drug roy­al­ty buy­er is go­ing pub­lic. And the low-key CEO di­vulges a few se­crets along the way

Pablo Legorreta is one of the most influential players in biopharma you likely never heard of.

Over the last 24 years, Legorreta’s Royalty Pharma group has become, by its own reckoning, the biggest buyer of drug royalties in the world. The CEO and founder has bought up a stake in a lengthy list of the world’s biggest drug franchises, spending $18 billion in the process — $2.2 billion last year alone. And he’s become one of the best-paid execs in the industry, reaping $28 million from the cash flow last year while reserving 20% of the cash flow, less expenses, for himself.

Fabrice Chouraqui, Cellarity CEO-partner (LinkedIn)

Drug de­vel­op­er, Big Phar­ma com­mer­cial ex­ec, now an up­start biotech chief — Fab­rice Chouraqui is ready to try some­thing new as a ‘CEO-part­ner’ at Flag­ship

Fabrice Chouraqui’s career has taken some big twists along his life journey. He got his PharmD at Université Paris Descartes and jumped into the drug development game for a bit. Then he took a sharp turn and went back to school to get his MBA at Insead before returning to pharma on the commercial side.

Twenty years later, after steadily rising through the ranks and journeying the globe to nab a top job as president of US pharma for the Basel-based Novartis, Chouraqui exited in another career switch. And now he’s headed into a hybrid position as a CEO-partner at Flagship, where he’ll take a shot at leading Cellarity — one of the VC’s latest paradigm-changing companies of the groundbreaking model that aspires to deliver a new platform to the world of drug R&D.

Head­ed to PhII: Al­lo­gene CEO David Chang com­pletes a pos­i­tive ear­ly snap­shot of their off-the-shelf CAR-T pi­o­neer

Allogene CEO David Chang has completed the upbeat first portrait of the biotech’s off-the-shelf CAR-T contender ALLO-501 at virtual ASCO today, keeping all eyes on a drug that will now try to go on to replace the first-wave personalized pioneers he helped create.

The overall response rate outlined in Allogene’s abstract for treatment-resistant patients with non-Hodgkin lymphoma slipped a little from the leadup, but if you narrow the patient profile to treatment-naïve patients — removing the 3 who had previous CAR-T therapy who didn’t respond, leaving 16 — the ORR lands at 75% with a 44% complete response rate. And 9 of the 12 responders remained in response at the data cutoff, offering a glimpse on durability that still has a long way to go before it can be completely nailed down.

Sanofi CEO Paul Hud­son has $23B burn­ing a hole in his pock­et. And here are some hints on how he plans to spend that

Sanofi has reaped $11.1 billion after selling off a big chunk of its Regeneron stock at $515 a share. And now everyone on the M&A side of the business is focused on how CEO Paul Hudson plans to spend it.

After getting stung in France for some awkward politicking — suggesting the US was in the front of the line for Sanofi’s vaccines given American financial support for their work, versus little help from European powers — Hudson now has the much more popular task of managing a major cash cache to pull off something in the order of a big bolt-on. Or two.

UP­DAT­ED: Backed by BAR­DA, Mer­ck jumps in­to Covid-19: buy­ing out a vac­cine, part­ner­ing on an­oth­er and adding an­tivi­ral to the mix

Merck execs are making a triple play in a sudden leap into the R&D campaign against Covid-19. And they have more BARDA cash backing them up on the move.

Tuesday morning the pharma giant simultaneously announced plans to buy an Austrian biotech that has been working on a preclinical vaccine candidate, added a collaboration on another vaccine with the nonprofit IAVI and inked a deal with Ridgeback Biotherapeutics on an early-stage antiviral.

As­traZeneca’s $7B ADC suc­ceeds where Roche failed, im­prov­ing sur­vival in gas­tric can­cer

Another day, another win for Enhertu.

The antibody-drug conjugate AstraZeneca promised up-to $7 billion to partner on has had a quite a few months, beginning with splashy results in a Phase II breast cancer trial, a rapid approval and, earlier this month, breakthrough designations in both non-small cell lung cancer and gastric cancer.

Now, at ASCO, the British pharma and their Japanese partner, Daiichi Sankyo, have shown off the data that led to the gastric cancer designation, which they’ll take back to the FDA. In a pivotal, 187-person Phase II trial, Enhertu shrunk tumors in 42.9% of third-line patients with HER2-positive stomach cancer, compared with 12.5% in a control arm where doctors prescribed their choice of therapy. Progression-free survival was 5.4 months for Enhertu compared to 3.5 months for the control.

Once a gem, now just a rock, Take­da punts PhI­II IBD drug as ri­vals mus­cle ahead

Back in 2016, when then-Shire CEO Flemming Ørnskov picked up a promising clinical-stage IBD drug from Pfizer, the Boston-based biotech dubbed it SHP647 and moved it into the gem section of the pipeline, with rosy expectations of registration-worthy Phase III data ahead.

This was a drug that the EC wanted Takeda to commit to selling off before it gave their blessing to its acquisition of Shire, to settle some deep-seated concerns revolving around the potential market overlap with their blockbuster rival Entyvio. And Takeda, which took on a heavy debt load to buy Shire, clearly wanted the cash to pay down debt.
