Arch joins Cel­gene, Chi­na in­vestors bankrolling a pi­o­neer­ing New York biotech start­up fo­cused on a new ap­proach to metas­ta­sis

Julio Aguirre-Ghiso has steered the work in his lab at Mount Sinai down some of the less-trav­eled path­ways of can­cer re­search. And it’s led him to launch a biotech — which is hav­ing its com­ing-out par­ty to­day in New York — that has now set out to de­vel­op new med­i­cines tai­lored for the field he’s been pi­o­neer­ing.

While a mas­sive amount of can­cer re­search has been de­vot­ed to a bet­ter un­der­stand­ing of tu­mors and new and bet­ter ways to kill tu­mor cells, Aguirre-Ghiso’s re­search has cen­tered on “dor­mant” dis­sem­i­nat­ed tu­mor cells, or DTCs, that can re­ac­ti­vate long af­ter drugs have wiped out all ap­pear­ances of can­cer — fu­el­ing a metasta­t­ic re­sponse that comes back to kill the pa­tient with near cer­tain­ty.

Ari Nowacek

That lab work has be­come the foun­da­tion of Hi­ber­Cell, a new com­pa­ny seed­ed by Arch last sum­mer and now de­but­ing with a $60.75 mil­lion launch round. Ari Nowacek, a prin­ci­pal at Arch who has helped cham­pi­on the com­pa­ny, is step­ping in as BD chief for the start­up, which has a small, vir­tu­al team of 5 now run­ning the show.

The syn­di­cate Nowacek helped form is telling about the way mon­ey comes to­geth­er in the bio­phar­ma world these days. Arch al­lied it­self, as it has be­fore, with Hill­house and 6 Di­men­sions out of Chi­na. Cel­gene, still op­er­at­ing as an in­de­pen­dent com­pa­ny in the lead-up to fi­nal­iz­ing the Bris­tol-My­ers buy­out, stepped in here as well. The NYC Life Sci­ences Fund, ea­ger to help fos­ter a Big Ap­ple hub, al­so con­tributed cash, along­side a group of uniden­ti­fied in­sti­tu­tion­al in­vestors and in­di­vid­u­als.

There isn’t any­thing par­tic­u­lar­ly new about the no­tion of dis­sem­i­na­tion in can­cer, says Alan Rig­by, the co-founder and CSO of the com­pa­ny. That dates back decades. But Aguirre-Ghiso’s lab has made some im­por­tant break­throughs in the bi­ol­o­gy of dis­sem­i­na­tion, find­ing that “soli­tary cells or mi­cro-clus­ters break away at ear­ly stages and dis­sem­i­nate ear­ly.” 

On his home page on Mount Sinai’s web­site, the sci­en­tist fur­ther ex­plains:

My lab has al­so de­signed an epi­ge­net­ic re­pro­gram­ming ther­a­py to in­duce dor­man­cy of DTCs, which is be­ing de­vel­oped in­to a clin­i­cal tri­al. We al­so dis­cov­ered that UPR sig­nal­ing can pro­mote the sur­vival of dor­mant tu­mor cells and that macrophages are key play­ers in the reg­u­la­tion of ear­ly dis­sem­i­na­tion and dor­man­cy. With mul­ti­ple col­lab­o­ra­tors we run an NCI-Tu­mor Mi­croen­vi­ron­ment Net­work Cen­ter that stud­ies the mi­croen­vi­ron­men­tal stress and dor­man­cy and de­vel­ops new tech­nolo­gies to im­age and tar­get metas­ta­sis. We al­so col­lab­o­rate to char­ac­ter­ize dor­man­cy in hu­man breast, prostate and head and neck can­cer DTCs and we study the epi­ge­net­ic reg­u­la­tion of DTC dor­man­cy. A ma­jor ef­fort in our lab is al­so to de­vel­op a trans­la­tion­al pro­gram with the phar­ma­ceu­ti­cal in­dus­try to iden­ti­fy po­ten­tial drugs to tar­get dor­mant dis­ease.

The re­search they’re do­ing has di­rect ap­pli­ca­tions that are par­tic­u­lar­ly suit­ed for the Chi­na mar­ket, adds Rig­by, cit­ing esophageal, gas­tric and liv­er can­cers. He adds that the launch round should get them in­to 2022, in­clud­ing a nice stretch af­ter they’re slat­ed to get in­to the clin­ic in 2020 or ear­ly ’21 with their first drug.

Rig­by al­so says that the team, which is like­ly to grow some­what, in-li­censed late pre­clin­i­cal drug can­di­dates that they’re work­ing with now. He de­clined to of­fer de­tails about those drugs, not un­usu­al for a start­up look­ing to get out ahead of any po­ten­tial ri­vals that may ap­pear now.

Gold for adults, sil­ver for in­fants: Pfiz­er's Pre­vnar 2.0 head­ed to FDA months af­ter Mer­ck­'s green light

Pfizer was first to the finish line for the next-gen pneumococcal vaccine in adults, but Merck beat its rival with a jab for children in June.

Now, two months after Merck’s 15-valent Vaxneuvance won the FDA stamp of approval for kids, Pfizer is out with some late-stage data on its 20-valent shot for infants.

Known as Prevnar 20 for adults, Pfizer’s 20vPnC will head to the FDA by the end of this year for an approval request in infants, the Big Pharma said Friday morning. Discussions with the FDA will occur first and more late-stage pediatric trials are expected to read out soon, informing the regulatory pathway in other countries and regions.

No­var­tis re­ports two pa­tient deaths af­ter treat­ment with Zol­gens­ma

Two children with spinal muscular atrophy have died after receiving Novartis’ Zolgensma, a gene therapy designed as a one-time treatment for the rare fatal disease.

The deaths, which resulted from acute liver failure, occurred in Russia and Kazakhstan, Novartis confirmed in a statement to Endpoints News. Having notified health authorities across all the markets where Zolgensma is available, it will update the drug label “to specify that fatal acute liver failure has been reported,” a spokesperson wrote.

House pass­es his­toric drug pric­ing re­forms, lin­ing up decades-in-the-mak­ing win for Biden and De­moc­rats

The US House of Representatives today voted along party lines (all Dems voted for it), 220-207 to pass new, wide-ranging legislation that will allow Medicare drug price negotiations for the first time ever, and cap seniors’ drug expenses to $2,000 per year and seniors’ insulin costs at $35 per month.

Setting up a major victory for President Joe Biden, representatives returned from their summer recess to pass the Inflation Reduction Act, even as many noted the bill would only modestly reduce inflation.

Sen­ate Fi­nance chair con­tin­ues his in­ves­ti­ga­tion in­to phar­ma tax­es with re­quests for Am­gen

Amgen is the latest pharma company to appear on the radar of Senate Finance Committee Chair Ron Wyden (D-OR), who is investigating the way pharma companies are using subsidiaries in low- or zero-tax countries to lower their tax bills.

Like its peers Merck, AbbVie and Bristol Myers Squibb, Wyden notes how Amgen uses its Puerto Rico operations to consistently pay tax rates that are substantially lower than the U.S. corporate tax rate of 21%, with an effective tax rate of 10.7% in 2020 and 12.1% in 2021.

FDA ap­proves sec­ond in­di­ca­tion for As­traZeneca and Dai­ichi's En­her­tu in less than a week

AstraZeneca and Daiichi Sankyo’s antibody-drug conjugate Enhertu scored its second approval in less than a week, this time for a subset of lung cancer patients.

Enhertu received accelerated approval on Thursday to treat adults with unresectable or metastatic non-small cell lung cancer (NSCLC) whose tumors have activating HER2 (ERBB2) mutations, and who have already received a prior systemic therapy.

J&J to re­move talc prod­ucts from shelves world­wide, re­plac­ing with corn­starch-based port­fo­lio

After controversially spinning out its talc liabilities and filing for bankruptcy in an attempt to settle 38,000 lawsuits, Johnson & Johnson is now changing up the formula for its baby powder products.

J&J is beginning the transition to an all cornstarch-based baby powder portfolio, the pharma giant announced on Thursday — just months after a federal judge ruled in favor of its “Texas two-step” bankruptcy to settle allegations that its talc products contained asbestos and caused cancer. An appeals court has since agreed to revisit that case.

CSL brings Se­qirus, Vi­for un­der par­ent um­brel­la brand in iden­ti­ty re­vamp

CSL is gathering its brands under the family name umbrella, renaming its vaccine and newly acquired nephrology specialty businesses with the parent initials.

CSL Seqirus and CSL Vifor join CSL Plasma and CSL Behring as the four now uniformly branded business units of the global biopharma. The Seqirus vaccine division was formed in 2015 with the combination of bioCSL and its purchase of Novartis’ flu vaccine business. CSL picked up Vifor Pharma late last year in an $11.7 billion deal for the nephrology, iron deficiency and cardio-renal drug developer.
