Gilead baits new al­liance with $45M up­front, div­ing in­to the busy pro­tein degra­da­tion field

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.”

Jay Brad­ner No­var­tis

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.

Up­dat­ed: Pfiz­er scoops up Glob­al Blood Ther­a­peu­tics and its sick­le cell ther­a­pies for $5.4B

Pfizer is dropping $5.4 billion to acquire Global Blood Therapeutics.

Just ahead of the weekend, word got out that Pfizer was close to clinching a $5 billion buyout — albeit with other potential buyers still at the table. The pharma giant, flush with cash from Covid-19 vaccine sales, apparently got out on top.

The deal immediately swells Pfizer’s previously tiny sickle cell disease portfolio from just a Phase I program to one with an approved drug, Oxbryta, plus a whole pipeline that, if all approved, the company believes could make for a $3 billion franchise at peak.

With drug pric­ing al­most done, Con­gress looks to wrap up FDA user fee leg­is­la­tion

The Senate won’t return from its summer recess until Sept. 6, but when it does, it officially has 18 business days to finalize the reauthorization of the FDA user fee programs for the next 5 years, or else thousands of drug and biologics reviewers will be laid off and PDUFA dates will vanish in the interim.

FDA commissioner Rob Califf recently sent agency staff a memo explaining how, “Our latest estimates are that we have carryover for PDUFA [Prescription Drug User Fee Act], the user fee funding program that will run out of funding first, to cover only about 5 weeks into the next fiscal year.”

As­traZeneca and Dai­ichi Sankyo sprint to mar­ket af­ter FDA clears En­her­tu in just two weeks

Regulators didn’t keep AstraZeneca and Daiichi Sankyo waiting long at all for their latest Enhertu approval.

The partners pulled a win on Friday in HER2-low breast cancer patients who’ve already failed on chemotherapy, just two weeks after submitting a supplemental BLA. While this isn’t the FDA’s fastest approval — Bristol Myers Squibb won an OK for its blockbuster checkpoint inhibitor Opdivo in just five days back in March — it comes well ahead of Enhertu’s original Q4 PDUFA date.

GSK and IQVIA launch plat­form of US vac­ci­na­tion da­ta, show­ing drop in adult rates

Throughout the Covid-19 pandemic, the issue of vaccine uptake has been a point of contention, but a new platform from GSK and IQVIA is hoping to shed more light on vaccine data, via new transparency and general awareness.

The two companies have launched Vaccine Track, a platform intended to be used by public health officials, medical professionals and others to strengthen data transparency and display vaccination trends. According to the companies, the platform is intended to aid in increasing vaccine rates and will provide data on trends to assist public health efforts.

Ab­b­Vie sur­veys emo­tion­al im­pact of chron­ic leukemia con­di­tion, finds 'roller coast­er' of emo­tions

Rare diseases often have more than just physical effects on patients — especially when it comes to chronic conditions. In the case of the rare slow-growing blood cancer chronic lymphocytic leukemia (CLL), AbbVie wanted to try to assess the mental and emotional toll on patients.

So it surveyed more than 300 CLL patients, caregivers and physicians. While each group differed in how they felt — caregivers overwhelmingly (81%) felt positive about their role, for instance — patients described a “roller coaster” of emotions traversing diagnosis to treatment to remission and even relapse for some.

UP­DAT­ED: In a fresh dis­ap­point­ment, Am­gen spot­lights a ma­jor safe­ty is­sue with KRAS com­bo

Amgen had hoped that its latest study matching its landmark KRAS G12C drug Lumakras with checkpoint inhibitors would open up its treatment horizons and expand its commercial potential. Instead, the combo spurred safety issues that blunted efficacy and forced the pharma giant to alter course on its treatment strategy, once again disappointing analysts who have been tracking the drug’s faltering sales and limited therapeutic reach.

Bernhardt Zeiher, outgoing Astellas CMO (Astellas)

Q&A: Astel­las' re­tir­ing head of de­vel­op­ment re­flects on gene ther­a­py deaths

For anyone who’s been following discussions about the safety alarms surrounding the adeno-associated viruses (AAV) commonly used to deliver gene therapy, Astellas should be a familiar name.

The Japanese pharma — which bought out Audentes Therapeutics near the end of 2019 and later built a gene therapy unit around the acquisition — rocked the field when it reported three patient deaths in a trial testing AT132, the lead program from Audentes designed to treat a rare muscle disease called X-linked myotubular myopathy (XLMTM).

When the company restarted the trial, it adjusted the dose and instituted a battery of other measures to try to prevent the same thing from happening again. But tragically, the first patient to receive the new regimen died just weeks after administration. The therapy remains under clinical hold, and just weeks ago, Astellas flagged another safety-related hold for a separate gene therapy candidate. In the process of investigating the deaths, the company has also taken flak about the way it disclosed information.

Big questions remain — questions that can have big implications about the future of AAV gene therapies.

Bernhardt Zeiher did not imagine any of it when he first joined Astellas as the therapeutic area leader in inflammation, immunology and infectious diseases. But his ascent to chief medical officer and head of development coincided almost exactly with Astellas’ big move into gene therapy, putting him often in the driver’s seat to grapple with the setbacks.

As Zeiher prepares to retire next month after a 12-year tenure — leaving the unfinished tasks to his successor, a seasoned cancer drug developer — he chatted with Endpoints News, in part, to discuss the effort to understand what happened, lessons learned and the criticism along the way.

The transcript has been lightly edited for length and clarity.

Endpoints: I want to also ask you a bit about the gene therapy efforts you’ve been working on. Astellas has really been at the forefront of discovering the safety concerns associated with AAV gene therapy. What’s that been like for you?

Zeiher: Well, I have to admit, it’s been a bit of a roller coaster. We acquired Audentes. Huge amount of enthusiasm. What we saw with AT132 — that was the lead program in XLMTM — was just remarkable efficacy. I mean, kids who went from being on ventilators, not able to eat for themselves, sit up, do things like that, to off ventilators, walking, you know, really — one investigator called it this Lazarus-like effect. It was just really dramatic efficacy. And then to have the safety events that occurred. So they actually occurred within that first year of the acquisition. So we had the three patient deaths. Me and my organization became very, very much involved. In fact, Ed Conner, who had been the chief medical officer, he left after some of the deaths, but I stepped in as the kind of acting chief medical officer, we had another chief medical officer who was involved, and then we had a fourth death, and I became acting again for a period of time.

Doug Ingram, Sarepta CEO

Sarep­ta li­cens­es next-gen AAV tech from Broad In­sti­tute in deal cov­er­ing five in­di­ca­tions — in­clud­ing Duchenne

Sarepta’s research agreement with the Broad Institute is taking the next step Monday.

The biotech will license a new group of adeno-associated viruses from the institute for an undisclosed upfront payment and milestone promises, the pair announced Monday morning. Under the agreement, Sarepta will have the rights to five neuromuscular and cardiac indications, including Duchenne muscular dystrophy, where it’s already well-versed.
