Bris­tol-My­ers Squibb brings Op­di­vo to a joint im­muno-on­col­o­gy pro­gram with Nek­tar’s new T cell am­pli­fi­er

Six years ago, when Steve Dober­stein took over as chief sci­en­tif­ic of­fi­cer at Nek­tar Ther­a­peu­tics, he set up a new bi­o­log­ics re­search group with an eye to ex­pand­ing on the biotech’s base of small mol­e­cules. The very first project they would un­der­take went on to be­come NK­TR-214, a pre­clin­i­cal bi­o­log­ic that the com­pa­ny be­lieves can play a role in im­muno-on­col­o­gy.

To­day, Nek­tar is pulling the wraps off a deal to col­lab­o­rate with Bris­tol-My­ers Squibbs’ I/O all­stars in R&D to see how their ex­per­i­men­tal drug match­es up with Op­di­vo, one of the lead­ers in the first wave of check­point in­hi­bi­tion.

“The com­bi­na­tion of the two med­ica­tions makes a tremen­dous amount of sense to me,” says Dober­stein. The same goes for Bris­tol-My­ers.

It’s easy to see why Bris­tol-My­ers would be in­ter­est­ed enough to foot half the costs of the up­com­ing work. Nek­tar has been run­ning an­i­mal stud­ies that demon­strat­ed their drug’s abil­i­ty to spur im­mune T cells to di­vide and ac­ti­vate, amp­ing up an im­mune re­sponse. Check­points dis­man­tle a can­cer cell’s de­fense sys­tem, leav­ing them vul­ner­a­ble to an at­tack. The syn­er­gies are ob­vi­ous. With the right check­point, which Bris­tol-My­ers feels it has, Nek­tar’s work has the po­ten­tial to “make cold tu­mors hot,” in Dober­stein’s words.

The work at Nek­tar cen­ters around a grow­ing un­der­stand of the role of the IL-2 path­way, says Dober­stein. If you hit the wrong IL-2 re­cep­tor, says the CSO, you’ll wind up trig­ger­ing reg­u­la­to­ry T cells, which sup­press the im­mune sys­tem. Hit the CD122 re­cep­tors, though, and you’ll amp up a T cell at­tack.

The plan now is to wrap up an on­go­ing safe­ty study, with some 30 sub­jects, and then branch out in­to 5 dif­fer­ent tu­mor types and 7 dif­fer­ent in­di­ca­tions, with a va­ri­ety of small ex­pan­sion stud­ies in each in the sec­ond half of 2017 to see if they can have an im­pact. Dober­stein sees po­ten­tial in all of them, though he doubts that they’ll hit on the full slate.

This is not your av­er­age col­lab­o­ra­tion sto­ry. There are no big biobucks in­volved. Every­body is hang­ing on to their rights. No one is plan­ning to con­quer block­buster mar­kets quite yet. But it is the kind of 50/50 ven­ture that Nek­tar likes for its first for­ay in­to the clin­ic. And it puts them at the same ta­ble as some of the best in the check­point busi­ness.

A joint steer­ing com­mit­tee is di­rect­ing the work, with plen­ty of in­put from BMS and Nek­tar in how things are done. Af­ter the first round, they can talk again about any piv­otal plans.

Im­muno-on­col­o­gy projects have been ex­plod­ing around the globe in re­cent months, and there’s some po­ten­tial here to do some­thing unique.

It’s a great place to start.

ZS Per­spec­tive: 3 Pre­dic­tions on the Fu­ture of Cell & Gene Ther­a­pies

The field of cell and gene therapies (C&GTs) has seen a renaissance, with first generation commercial therapies such as Kymriah, Yescarta, and Luxturna laying the groundwork for an incoming wave of potentially transformative C&GTs that aim to address diverse disease areas. With this renaissance comes several potential opportunities, of which we discuss three predictions below.

Allogenic Natural Killer (NK) Cells have the potential to displace current Cell Therapies in oncology if proven durable.

Despite being early in development, Allogenic NKs are proving to be an attractive new treatment paradigm in oncology. The question of durability of response with allogenic therapies is still an unknown. Fate Therapeutics’ recent phase 1 data for FT516 showed relatively quicker relapses vs already approved autologous CAR-Ts. However, other manufacturers, like Allogene for their allogenic CAR-T therapy ALLO-501A, are exploring novel lymphodepletion approaches to improve persistence of allogenic cells. Nevertheless, allogenic NKs demonstrate a strong value proposition relative to their T cell counterparts due to comparable response rates (so far) combined with the added advantage of a significantly safer AE profile. Specifically, little to no risk of graft versus host disease (GvHD), cytotoxic release syndrome (CRS), and neurotoxicity (NT) have been seen so far with allogenic NK cells (Fig. 1). In addition, being able to harness an allogenic cell source gives way to operational advantages as “off-the-shelf” products provide improved turnaround time (TAT), scalability, and potentially reduced cost. NKs are currently in development for a variety of overlapping hematological indications with chimeric antigen receptor T cells (CAR-Ts) today, and the question remains to what extent they will disrupt the current cell therapy landscape.

What kind of biotech start­up wins a $3B syn­di­cate, woos a gallery of mar­quee sci­en­tists and re­cruits GSK's Hal Bar­ron as CEO in a stun­ner? Let Rick Klaus­ner ex­plain

It started with a question about a lifetime’s dream on a walk with tech investor Yuri Milner.

At the beginning of the great pandemic, former NCI chief and inveterate biotech entrepreneur Rick Klausner and the Facebook billionaire would traipse Los Altos Hills in Silicon Valley Saturday mornings and talk about ideas.

Milner’s question on one of those mornings on foot: “What do you want to do?”

Eu­ro­pean Par­lia­ment signs off on strength­en­ing drug reg­u­la­tor's abil­i­ty to tack­le short­ages

The European Parliament on Thursday endorsed a plan to increase the powers of the European Medicines Agency, which will be better equipped to monitor and mitigate shortages of drugs and medical devices.

By a vote of 655 to 31, parliament signed off on a provisional agreement reached with the European Council from last October, in which the EMA will create two shortage steering groups (one for drugs, the other for devices), a new European Shortages Monitoring Platform to facilitate data collection and increase transparency, and on funding for the work of the steering groups, task force, working parties and expert panels that are to be established.

Sec­ondary patents prove to be key in biosim­i­lar block­ing strate­gies, re­searchers find

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.

'Al­tos was re­al­ly a once-in-a-life­time op­por­tu­ni­ty': Hal Bar­ron re­flects on his big move

By all accounts, Hal Barron had one of the best jobs in Big Pharma R&D. He made more than $11 million in 2020, once again reaping more than his boss, Emma Walmsley, who always championed him at every opportunity. And he oversaw a global R&D effort that struck a variety of big-dollar deals for oncology, neurodegeneration and more.

Sure, the critics never let up about what they saw as a rather uninspiring late-stage pipeline, where the rubber hits the road in the Big Pharma world’s hunt for the next big near-term blockbuster, but the in-house reviews were stellar. And Barron was firmly focused on bringing up the success rate in clinical trials, holding out for the big rewards of moving the dial from an average 10% success rate to 20%.

Kenneth Galbraith, incoming Zymeworks CEO

Zymeworks re­places half its C-suite, aims to lay off 25% of to­tal work­force as new CEO takes over

New Zymeworks CEO Kenneth Galbraith is aiming to hit the ground running when his tenure officially begins next month, but he’ll be doing so with a much different looking team.

In a lengthy press release outlining the biotech’s 2022 goals, Galbraith said Zymeworks will be laying off at least 25% of its staff over the course of the year. Half of its C-suite will also be replaced immediately as Galbraith looks to remake the company in his image after Ali Tehrani, Zymeworks’ founder and CEO since 2003, stepped down two weeks ago.

Hal Barron (GSK via YouTube)

GSK R&D chief Hal Bar­ron jumps ship to run a $3B biotech start­up, Tony Wood tapped to re­place him

In a stunning switch, GlaxoSmithKline put out word early Wednesday that R&D chief Hal Barron is exiting the company after 4 years — a relatively brief run for the man chosen by CEO Emma Walmsley in late 2017 to turn around the slow-footed pharma giant.

Barron is being replaced by Tony Wood, a close associate of Barron’s who’s taking one of the top jobs in Big Pharma R&D. He’ll be closer to home, though, for GSK. Barron has been running a UK and Philadelphia-based research organization from his perch in San Francisco.

CBO: Medicare ne­go­ti­a­tions will ham­per drug de­vel­op­ment more than pre­vi­ous­ly thought

As President Biden’s Build Back Better Act — and, with it, potentially the Democrats’ last shot at major drug pricing reforms in the foreseeable future — remains on life support, the Congressional Budget Office isn’t helping their case.

The CBO last week released a new slide deck, outlining an update to its model on how Medicare negotiations might take a bite out of new drugs making it to market. The new model estimates a 10% long-term reduction in the number of new drugs, whereas a previous CBO report from August estimated that 8% fewer new drugs will enter the market over 30 years.
