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

With just days before President Joe Biden’s Covid-19 booster rollout is set to go into effect, an FDA advisory committee appeared on the verge of not recommending boosters for anyone in the US before a last-minute change of wording laid the groundwork for older adults to have access to a third dose.

The FDA’s adcomm on Vaccines and Related Biological Products (VRBPAC) roundly rejected Pfizer/BioNTech booster shots for all individuals older than 16 by a 16-2 vote Friday afternoon. Soon after, however, the agency posed committee members a new question limiting booster use to the 65-and-older population and individuals at high risk of disease due to occupational exposure or comorbidities.

AstraZeneca and Japanese drugmaker Daiichi Sankyo think they’ve struck gold with their next-gen ADC drug Enhertu, which has shown some striking data in late-stage breast cancer trials and early solid tumor tests. Getting into earlier patients is now the goal, starting with Enhertu’s complete walkover of a Roche drug in second-line breast cancer revealed Saturday.

Enhertu cut the risk of disease progression or death by a whopping 72% (p=<0.0001) compared with Roche’s ADC Kadcyla in second-line unresectable and/or metastatic HER2-positive breast cancer patients who had previously undergone treatment with a Herceptin-chemo combo, according to interim data from the Phase III DESTINY-Breast03 head-to-head study presented at this weekend’s #ESMO21.

In recent months, the battle for PD-(L)1 dominance has spilled over into early cancer with Merck’s Keytruda and Bristol Myers Squibb’s Opdivo all alone on the front lines. Keytruda now has another shell in its bandolier, and it could spell a quick approval.

Keytruda cut the risk of relapse or death by 35% over placebo (p=0.00658) in high-risk, stage 2 melanoma patients who had previously undergone surgery to remove their tumors, according to full data from the Phase III KEYNOTE-716 presented Saturday at #ESMO21.

Merck has worked hard to bring its I/O blockbuster Keytruda into earlier and earlier lines of therapy, and now the wonder drug appears poised to make a quick entry into early advanced cervical cancer.

A combination of Keytruda and chemotherapy with or without Roche’s Avastin cut the risk of death by 33% over chemo with or without Avastin (p=<0.001) in first-line patients with persistent, recurrent or metastatic cervical cancer, according to full data from the Phase III KEYNOTE-826 study presented Saturday at #ESMO21.

Everest Medicines is on a roll with two licensing deals in one week.

The Shanghai-based biotech has paid Sinovent and SinoMab $12 million upfront for the rights to a BTK inhibitor for renal diseases, the company announced Thursday. The deal comes just days after Everest came away with rights to a Covid-19 vaccine in China, Taiwan, Singapore, Thailand and Indonesia.

Everest will pay Sinovent and SinoMab up to $549 million in milestone payments and royalties. The agreement includes tech transfer of Sinovent and SinoMab’s manufacturing process for the candidate, named XNW1011.
