Mer­ck’s PhI­II liv­er can­cer study for Keytru­da fails on two key end­points, just three months af­ter the FDA gave it the green light

In a rare set­back, Mer­ck has suf­fered a key Phase III fail­ure for Keytru­da that could put a crimp in its sales prospects.

Roy Baynes

The phar­ma gi­ant re­port­ed af­ter the mar­ket closed on Tues­day that Keytru­da failed the KEYNOTE-240 study for he­pa­to­cel­lu­lar car­ci­no­ma, the most com­mon type of liv­er can­cer. The tri­al missed on both over­all sur­vival as well as pro­gres­sion-free sur­vival. That news ar­rived just 3 months af­ter the FDA of­fered an ac­cel­er­at­ed ap­proval on liv­er can­cer based on their ear­li­er mid-stage da­ta for the drug. 

Stay­ing on the mar­ket re­quires Mer­ck to put up pos­i­tive piv­otal da­ta. Ques­tions about the drug’s fu­ture in liv­er can­cer dinged Mer­ck’s stock $MRK, which dropped slight­ly more than 1% af­ter the re­lease hit.

Mer­ck was quick to note that it’s study­ing Keytru­da in a range of oth­er liv­er can­cer stud­ies, but the ad­van­tage here has clear­ly switched to Op­di­vo for now, which has been drag­ging steadi­ly be­hind Keytru­da af­ter falling short on lung can­cer, where Mer­ck holds first-line ad­van­tage.

This wasn’t the on­ly con­fir­ma­to­ry Phase III study to flop. Just weeks ago Eli Lil­ly had to sus­pend mar­ket­ing of Lartru­vo af­ter its piv­otal for soft tis­sue sar­co­ma failed. These back-to-back set­backs, though, are un­like­ly to slow down the FDA, which has proved ea­ger to hand out ac­cel­er­at­ed OKs — par­tic­u­lar­ly for can­cer drugs — in re­cent years.

“While we are dis­ap­point­ed KEYNOTE-240 did not meet its co-pri­ma­ry end­points, the re­sults for over­all sur­vival, pro­gres­sion-free sur­vival and ob­jec­tive re­sponse rate are gen­er­al­ly con­sis­tent with find­ings from the Phase II study, KEYNOTE-224, which led to the ac­cel­er­at­ed ap­proval of KEYTRU­DA for the treat­ment of pa­tients with he­pa­to­cel­lu­lar car­ci­no­ma who have been pre­vi­ous­ly treat­ed with so­rafenib,” said Roy Baynes, se­nior vice pres­i­dent and head of glob­al clin­i­cal de­vel­op­ment, chief med­ical of­fi­cer, Mer­ck Re­search Lab­o­ra­to­ries.

Forge Bi­o­log­ics’ cGMP Com­pli­ant and Com­mer­cial­ly Vi­able Be­spoke Affin­i­ty Chro­matog­ra­phy Plat­form

Forge Biologics has developed a bespoke affinity chromatography platform approach that factors in unique vector combinations to streamline development timelines and assist our clients in efficiently entering the clinic. By leveraging our experience with natural and novel serotypes and transgene conformations, we are able to accelerate affinity chromatography development by nearly 3-fold. Many downstream purification models are serotype-dependent, demanding unique and time-consuming development strategies for each AAV gene therapy product1. With the increasing demand to propel AAV gene therapies to market, platform purification methods that support commercial-scale manufacturing of high-quality vectors with excellent safety and efficacy profiles are essential.

Cy­to­ki­net­ics’ ALS drug fails PhI­II, leav­ing the biotech with a sin­gle late-stage prospect

Cytokinetics’ candidate for the muscle disease amyotrophic lateral sclerosis, or ALS, failed a Phase III trial, the Bay Area biotech announced Friday morning.

At a second interim analysis of the trial, an independent review committee recommended that Cytokinetics discontinue its COURAGE-ALS trial for reldesemtiv, as it “found no evidence of effect” compared to placebo on the primary or key secondary endpoints.

Austin biotech Mol­e­c­u­lar Tem­plates lays off more than 100 staffers as pipeline nar­rows

Molecular Templates is ridding itself of a Phase I HER2 asset and fine-tuning its pipeline to focus on three programs and a preclinical Bristol Myers Squibb collaboration. With the narrowed scope on its so-called engineered toxin bodies, the Austin, TX biotech is laying off about half of its staff.

That’s a little more than 100 employees, per an SEC filing. Molecular’s layoffs, approved by its board Wednesday, add to the dozens of pullbacks in the industry in the first three months of 2023.

Mathai Mammen, FogPharma's next CEO

Math­ai Mam­men hands in J&J's R&D keys to lead Greg Ver­dine’s Fog­Phar­ma 

In the early 1990s, Mathai Mammen was a teaching assistant in Greg Verdine’s Science B46 course at Harvard. In June, the former R&D head at Johnson & Johnson will succeed Verdine as CEO, president and chair of FogPharma, the same month the seven-year-old biotech kickstarts its first clinical trial.

After leading R&D at one of the largest drugmakers in the world, taking the company through more than half a dozen drug approvals in the past few years, not to mention a Covid-19 vaccine race, Mammen departed J&J last month and will take the helm of a Cambridge, MA biotech attempting to go after what Verdine calls the “true emperor of all oncogenes” — beta-catenin.
