#AACR: Mer­ck spot­lights piv­otal Keytru­da/chemo da­ta, hop­ing to break down skep­ti­cism to its front­line lung can­cer duo

CHICA­GO — Mer­ck wowed the im­muno-on­col­o­gy mar­ket ear­ly this year with the head­line news that its piv­otal KEYNOTE-189 study demon­strat­ed a clear suc­cess for Keytru­da com­bined with chemo in treat­ing front­line lung can­cer cas­es. And at AACR in Chica­go to­day, its in­ves­ti­ga­tors spelled out the promis­ing re­sults — demon­strat­ing that the com­bo re­duced the risk of death by half with a haz­ard ra­tio of 0.49 — as Mer­ck looks to hold back a wave of ma­jor league com­peti­tors as it carves out a big­ger share of the block­buster lung can­cer mar­ket.

In the first look at hard da­ta for non­squa­mous non-small cell lung can­cer — which will be care­ful­ly com­pared with the da­ta from Bris­tol-My­ers — re­searchers say that their com­bo clear­ly beat out chemo alone on over­all sur­vival, though the fi­nal OS rate for the com­bi­na­tion has not yet been reached. 

Leena Gand­hi

The great­est ben­e­fit among these pa­tients was among the high PD-L1 ex­pressers, but chief in­ves­ti­ga­tor Leena Gand­hi at the Perl­mut­ter Can­cer Cen­ter at NYU Lan­gone Health al­so says that the sur­vival ben­e­fit could be seen across the board on PD-L1 ex­pres­sion.

Mer­ck’s piv­otal da­ta from the -189 study are cru­cial to their cam­paign to be the leader in check­point in­hi­bi­tion. Ap­proved by the FDA for front­line cas­es on Phase II da­ta — but re­ject­ed in Eu­rope — Mer­ck says that physi­cians have been slow to change the way they treat lung can­cer. Now Mer­ck be­lieves this da­ta should re­solve any doubts as Keytru­da be­comes the stan­dard of care in this crit­i­cal­ly im­por­tant set­ting.

At 12 months, Gand­hi tells me, 69.2% of the com­bo arm was still alive, com­pared to 49.4% in the con­trol arm. 

Ac­cord­ing to Mer­ck, pa­tients in the drug arm were 51% less like­ly to die than the con­trol group, and those in the high­est PD-L1 score group were 58% less like­ly to die. The rates held up de­spite a high num­ber of pa­tients who crossed over to the com­bo af­ter their dis­ease pro­gressed.

“The great­est ben­e­fit was seen in those with high lev­els of PD-L1 ex­pres­sion, sug­gest­ing that PD-L1 does have some pre­dic­tive val­ue even in this com­bi­na­tion set­ting,” Gand­hi said. 

Me­di­an PFS was 8.8 months for the pem­brolizum­ab arm, ver­sus 4.9 months for the con­trol group.

Some an­a­lysts have been wait­ing to see if the ben­e­fits for the com­bo leaned pri­mar­i­ly to high PD-L1 ex­pressers, leav­ing ri­vals an open­ing in divvy­ing up the mar­ket on the rest. But Gand­hi says the sur­vival ad­van­tages are clear re­gard­less of PD-L1 sta­tus. That marks a trend that many are see­ing, where new ther­a­peu­tic ap­proach­es are de­liv­er­ing en­hanced re­sults for the high-PD-L1 group while re­tain­ing promis­ing re­sults for the full field.

“There was no group that didn’t get a sur­vival ben­e­fit in this study,” Gand­hi says, with the re­sults of­fer­ing a prac­tice-chang­ing set of re­sults. She al­so says she wants to ful­ly con­sid­er the fi­nal da­ta from Check­mate-227 (Bris­tol-My­ers) and IM­pow­er-150 (Roche) as she pon­ders the chang­ing scene for prac­ti­tion­ers.

2023 Spot­light on the Fu­ture of Drug De­vel­op­ment for Small and Mid-Sized Biotechs

In the context of today’s global economic environment, there is an increasing need to work smarter, faster and leaner across all facets of the life sciences industry.  This is particularly true for small and mid-sized biotech companies, many of which are facing declining valuations and competing for increasingly limited funding to propel their science forward.  It is important to recognize that within this framework, many of these smaller companies already find themselves resource-challenged to design and manage clinical studies themselves because they don’t have large teams or in-house experts in navigating the various aspects of the drug development journey. This can be particularly challenging for the most complex and difficult to treat diseases where no previous pathway exists and patients are urgently awaiting breakthroughs.

Gos­samer’s Fa­heem Has­nain de­fends a round of pos­i­tive PAH da­ta as a clear win. But can these PhII re­sults stand up to scruti­ny?

Gossamer Bio $GOSS posted a statistically significant improvement for its primary endpoint in the key Phase II TORREY trial for lead drug seralutinib on Tuesday morning. But CEO Faheem Hasnain has some explaining to do on the important secondary of the crucial six-minute walk distance test — which will be the primary endpoint in Phase III — as the data on both endpoints fell short of expectations, missing one analyst’s bar on even modest success.

Eisai and METAvivor plan to debut the latest 'This is MBC' campaign at the San Antonio Breast Cancer Symposium (SABCS).

Ei­sai re-ups metasta­t­ic breast can­cer aware­ness cam­paign with strik­ing pa­tient pho­tographs

Eisai is debuting the newest ads in its long-running “This is MBC” campaign this week. In what’s become an annual tradition, Eisai and metastatic breast cancer advocacy partner METAvivor will show the striking photographs of people living with metastatic breast cancer first at the San Antonio Breast Cancer Symposium (SABCS).

The new “Imagine” campaign features 12 patients photographed around waterfalls to symbolize that same kind of sudden drop into a pool that MBC causes in a person’s life, said Beth Fairchild, co-founder of #CancerCulture who was the president of METAvivor six years ago when the campaign began. Fairchild, who is living with MBC, has helped create all of the annual “This is MBC” campaigns.

Pfiz­er and BioN­Tech look to toss Mod­er­na patent suit, call­ing claims 'unen­force­able'

Pfizer and BioNTech took a swing at Moderna’s Covid-19 patent claims in Massachusetts federal court on Monday, calling them “invalid,” “overbroad” and “unenforceable.”

The defendants also filed counterclaims against the Cambridge, MA-based biotech, seeking a dismissal of the case, recovery of court fees and an official judgment invalidating Moderna’s claims.

Moderna sued Pfizer and BioNTech back in August, alleging that the partners’ Covid-19 vaccine Comirnaty copied parts of Moderna’s vaccine technology patented before the pandemic, when it was developing an mRNA vaccine for MERS, another respiratory illness.

US sup­ports ex­ten­sion for Covid-19 IP waiv­er de­ci­sion

After much debate, the US government is now calling for a deadline extension to discuss a controversial potential IP waiver for Covid-19 diagnostics and therapeutics.

Over the last five months, the Office of the United States Trade Representative said it has consulted with members of Congress, public health advocates, organized labor groups, academics, think tanks, companies and trade associations on the WTO’s recent TRIPS agreement, which established a 5-year waiver of certain patent requirements on Covid-19 vaccines.

Glen­mark hit with warn­ing let­ter over pro­ce­dures, qual­i­ty con­trol is­sues at In­dia man­u­fac­tur­ing plant

The generics producer Glenmark Pharmaceuticals has been handed a warning letter by US regulators.

The letter, which was sent to the manufacturer on Nov. 22, noted issues from an inspection over the summer at Glenmark’s facility in the town of Colvale, India, in the state of Goa.

According to the letter, the FDA found that Glenmark’s investigation of rejected batches of drugs “failed to extend to other batches, dosage strengths, and drug products.” The warning letter also noted that the site had failed to establish “adequate written procedures” for production and process control to ensure drugs have the correct strength, quality and purity.

Klick Health is lighting the way, literally, this holiday season to encourage connection for lonely seniors in long-term care facilities.

Klick Health an­nu­al hol­i­day spot­light se­nior lone­li­ness and the pow­er of con­nec­tion

Every year Klick Health leans into a cause for the holidays, and this year it’s highlighting the sometimes lonely season for seniors. So Klicksters, as employees call themselves, decided to brighten one nursing home community in hopes of inspiring others to do the same.

Klick literally lit up the Tony Stacey Centre for Veterans Care, a long-term care home in Toronto where 75% of residents receive no visitors during the holiday season. The agency brought staff and family along with lighting crews and musicians for a “Light the Way” event, creating a video of the experience debuting on Tuesday.
