Mark Gold­smith Rev­o­lu­tion

Gilead is jump­ing on board the pro­tein degra­da­tion band­wag­on. And they’re turn­ing to a low-pro­file Third Rock start­up for the ex­per­tise. But if you were look­ing for a trans­for­ma­tion­al deal to kick up fresh en­thu­si­asm for Gilead, you’ll have to re­main pa­tient.

This one will have a long way to go be­fore they get in­to the clin­ic.

The big biotech said Wednes­day morn­ing that it is pay­ing $45 mil­lion up­front and re­serv­ing a whop­ping $2.3 bil­lion in biotech bucks if San Fran­cis­co-based Nurix can point the way to new can­cer ther­a­pies, as well as drugs for oth­er, un­spec­i­fied dis­eases.

Still in the pre­clin­i­cal phase 5 years af­ter Mark Gold­smith — dis­patched by Third Rock to launch West Coast biotechs and now CEO at Rev­o­lu­tion — boot­ed up the com­pa­ny with an un­usu­al­ly lean $25 mil­lion ven­ture round, Nurix quick­ly picked up an im­pres­sive $150 mil­lion up­front from a new deal back in 2015 with the then pro­lif­ic Cel­gene. It has 2 pre­clin­i­cal ef­forts un­der­way, one in house and a CDL-B pro­gram paired with Cel­gene, which will soon mi­grate to Bris­tol-My­ers Squibb.

Gilead CSO John McHutchi­son counts him­self as an ad­mir­er of Nurix’s tech plat­form, hop­ing it pans out “as we con­tin­ue to build a pipeline of small mol­e­cule ther­a­peu­tics for pa­tients with can­cers and oth­er dis­eases.”

The fo­cus at Nurix, and now Gilead, is the ubiq­ui­tin sys­tem and key en­zymes called E3 lig­as­es. Pro­tein degra­da­tion has proved a promis­ing ap­proach in on­col­o­gy, at­tract­ing a group of play­ers to the field. Arv­inas is one of the most promi­nent, adding an ag deal with Bay­er a few days ago with $115 mil­lion built-in up­front. But it is by no means play­ing so­lo in the sec­ond-gen pro­tein degra­da­tion field. Ri­vals to the pro­tein degra­da­tion ti­tle in­clude C4 Ther­a­peu­tics — out of Jay Brad­ner’s lab at Dana Far­ber be­fore he took the helm at NI­BR — and the start­up Kymera. And not sur­pris­ing­ly, Brad­ner — who now runs NI­BR — re­cent­ly forged a close re­la­tion­ship with UC Berke­ley on pro­tein degra­da­tion as well.

Nurix gets a chance to co-pro­mote drugs in the deal they did with Gilead, pro­vid­ed they pick up half the de­vel­op­ment costs.

Biohaven is at risk of making a habit of disappointing its investors. 

Late Friday the biotech $BHVN reported that the FDA had rejected its application for riluzole, an old drug that they had made over into a sublingual formulation that dissolves under the tongue. According to Biohaven, the FDA had a problem with the active ingredient used in a bioequivalence study back in 2017, which they got from the Canadian drugmaker Apotex.

Let the long battle for biosimilars in the cancer space begin.

Amgen has launched its Avastin and Herceptin copycats — licensed from the predecessors of Allergan — almost two years after the FDA had stamped its approval on Mvasi (bevacizumab-awwb) and three months after the Kanjinti OK (trastuzumab-anns). While the biotech had been fielding biosimilars in Europe, this marks their first foray in the US — and the first oncology biosimilars in the country.

→ On the same day it announced a $17.5 million Series C, life sciences and health data company Seer unveiled that it had lured former FDA commissioner and ex-CMS administrator Mark McClellan on to its board. “Mark’s deep understanding of the health care ecosystem and visionary insights on policy reform will be crucial in informing our thinking as we work to bring our liquid biopsy and life sciences products to market,” said Seer chief and founder Omid Farokhzad in a statement.

Gilead CEO Daniel O’Day’s new task hunting up a CSO for the company isn’t stopping the industry’s dominant antiviral player from doing pipeline deals.

The big biotech today snapped up 3 preclinical antiviral programs from pharma giant Novartis, with drugs promising to treat human rhinovirus, influenza and herpes viruses. We don’t know what the upfront is, but the back end has $291 million in milestones baked in.
