Arv­inas has inked an­oth­er Big Phar­ma part­ner­ship to get their pro­tein degra­da­tion en­gines revving — for both hu­mans and crops.

All told, the Ger­man con­glom­er­ate is wa­ger­ing $115 mil­lion on the po­ten­tial of Arv­inas’ tech plat­form, which us­es an E3 lig­ase to tag tar­get pro­teins with an ubiq­ui­tin, flush­ing these dis­ease cul­prits down the cell’s nat­ur­al “garbage dis­pos­al.” And Bay­er is in for the whole pack­age, with a col­lab­o­ra­tion, an eq­ui­ty in­vest­ment and a joint ven­ture in play.

A har­bin­ger of the pro­tein degra­da­tion space, Arv­inas comes of age as peers at C4 Ther­a­peu­tics and Kymera al­so gains pop­u­lar­i­ty among the likes of Bio­gen, Ver­tex and Glax­o­SmithK­line. Com­pared to the tra­di­tion­al in­hi­bi­tion ap­proach, get­ting rid of prob­lem­at­ic pro­teins promis­es to be a much more durable so­lu­tion for dis­eases like can­cer.

“Be­cause PRO­TACs don’t in­hib­it the tar­get pro­tein’s en­zy­mat­ic ac­tiv­i­ty, but bind their tar­gets with high se­lec­tiv­i­ty, it may be pos­si­ble to re­tool pre­vi­ous­ly in­ef­fec­tive in­hibitor mol­e­cules as PRO­TACs for next-gen­er­a­tion med­i­cines for pa­tients,” Jo­erg Moeller, Bay­er’s head of R&D, said in a state­ment.

On the ther­a­peu­tic side, Bay­er’s to­tal com­mit­ment — up­front, R&D sup­port plus eq­ui­ty — amounts to $60 mil­lion. It gets them the rights to nov­el lead struc­tures Arv­inas gen­er­ates in the process but doesn’t cov­er the ad­di­tion­al $685 mil­lion in po­ten­tial mile­stone pay­ments.

The pact will span car­dio­vas­cu­lar, on­co­log­i­cal and gy­ne­co­log­i­cal dis­eases.

The oth­er $55 mil­lion in the deal goes, in the course of six years, to a joint ven­ture set up to ex­plore how Arv­inas’ tech­nol­o­gy can tack­le the weeds, in­sects or dis­eases en­dem­ic in agri­cul­ture. Where pre­vi­ous crop pro­tec­tion ef­forts have suc­cumbed to re­sis­tance, pro­tein degra­da­tion may be able to re­vive them, the part­ners said.

“As the first com­pa­ny found­ed to ex­plore tar­get­ed pro­tein degra­da­tion, we’ve been ex­cit­ed about the po­ten­tial to im­prove the lives of pa­tients since our in­cep­tion,” said Arv­inas CEO John Hous­ton. “This col­lab­o­ra­tion en­ables us not on­ly to ex­pand our plat­form in­to new ther­a­peu­tic ar­eas, but al­so be­gins a new jour­ney in ap­ply­ing our ap­proach to agri­cul­ture.”

The cash ex­changed trumps pre­vi­ous part­ner­ships, in which Genen­tech and Pfiz­er paid less to get dis­cov­ery al­liances start­ed but pledged biobucks, great­ly rais­ing Arv­inas’ pro­file be­fore it even got in­to the clin­ic. Its lead ther­a­py in prostate can­cer is now in Phase I tri­als.

Im­age: Shut­ter­stock

While the US biosimilars industry has generally been a disappointment since its inception, with FDA approving 33 biosimilars since 2015, just a fraction of those have immediately followed their approvals with launches. And more than a handful of biosimilars for two of the biggest blockbusters of all time — AbbVie’s Humira and Amgen’s Enbrel — remain approved by FDA but still have not launched because of legal settlements.

Kura Oncology is clear to resume studies for its early-stage leukemia program after the FDA lifted a clinical hold Thursday afternoon.

Regulators had placed the hold on a Phase Ib study of KO-539, an experimental oral treatment for some genetic subsets of acute myeloid leukemia last November after a patient died while taking the drug. Kura expects to begin enrolling patients again imminently, CEO Troy Wilson told Endpoints News.
