Pfiz­er lays down its hand on Chi­nese biosims, of­fload­ing its 3-year-old plant to WuXi Bi­o­log­ics as com­pe­ti­tion grows

Pfiz­er is in down­siz­ing mode af­ter a hefty spin­off of its Up­john gener­ics unit and a full-scale piv­ot to­ward brand­ed meds. That move left Pfiz­er’s biosim unit in lim­bo, and now the drug­mak­er is mak­ing an ear­ly ex­it from the Chi­nese mar­ket as it faces a slate of un­ex­pect­ed com­peti­tors.

Pfiz­er has ef­fec­tive­ly bailed on its shot at the Chi­nese biosim­i­lars mar­ket by of­fload­ing its three-year-old plant in Hangzhou to WuXi Bi­o­log­ics, the Chi­nese firm said ear­li­er this week.

Pfiz­er ini­tial­ly plant­ed $350 mil­lion in­to the Hangzhou site back in 2016 as part of plan to cre­ate copy­cats of Roche’s Avastin and Her­ceptin as well as Ab­b­Vie’s Hu­mi­ra. But Pfiz­er was most­ly beat­en to the punch af­ter Fo­s­un Phar­ma cracked the mar­ket open with Chi­na’s first ap­proved biosim, a copy of Roche’s Rit­ux­an, back in Feb­ru­ary 2019.

In the fol­low­ing year, two Hu­mi­ra copies al­so hit the mar­ket from do­mes­tic drug­mak­ers Hen­lius and In­novent Bi­o­log­ics. Sun­shine Guo­jian Phar­ma­ceu­ti­cal scored an ap­proval for its copy of Her­ceptin, and In­novent al­so won nods for its ver­sions of Avastin and Rit­ux­an.

With so many play­ers flood­ing the mar­ket, Pfiz­er has cho­sen to take a back seat in that emerg­ing mar­ket as it looks to a fu­ture with­out its Up­john gener­ics unit af­ter a spin­off and merg­er with My­lan last year.

Mean­while, WuXi Bi­o­log­ics will pick up the plant, which it says hous­es two 538,000-square-foot fa­cil­i­ties, with two 2000-liter sin­gle-use biore­ac­tors, room to dou­ble in size and ca­pac­i­ty for fill-fin­ish. WuXi ex­pects to close the deal in the first half of the year and will ab­sorb Pfiz­er’s work­force to start pro­duc­ing short­ly af­ter clos­ing, the com­pa­ny said in a state­ment.

Rid­ing a hot hand in bi­o­log­ics, WuXi has seen rapid ex­pan­sion in re­cent years and closed an­oth­er deal close on the heels of its pend­ing trans­ac­tion with Pfiz­er.

On Thurs­day, WuXi an­nounced it would ac­quire Chi­na’s in­vest­ment firm CBC Group and sub­sidiary Ming Bioven­tures, which would give WuXi 90% con­trol­ling stake in CMAB Bio­phar­ma Group. The buy­out comes with up to 7,000 liters of drug ca­pac­i­ty and a glob­al net­work of 250 em­ploy­ees, the com­pa­ny said in a re­lease.

Back in De­cem­ber, WuXi un­veiled plans to drop $183.3 mil­lion to ac­quire Bay­er’s 330,000 square-foot drug sub­stance fa­cil­i­ty in Wup­per­tal, Ger­many, as it seeks to en­hance a sup­ply net­work of Covid-19 vac­cines and oth­er bi­o­log­ics. The newest fa­cil­i­ty will al­so add to WuXi’s “glob­al dual sourc­ing” strat­e­gy to add re­dun­dan­cy in­to its sup­ply chain, CEO Chris Chen said at the time.

The fa­cil­i­ty hous­es three 1,000-liter per­fu­sion re­ac­tors for bi­o­log­ics as well as six 1,000-liter fed-batch biore­ac­tors, WuXi said. Those two man­u­fac­tur­ing lines will in­clude in­de­pen­dent down­stream suites, ac­cord­ing to a re­lease.

Some of the most time- and cost-consuming components of clinical research center on gathering, analyzing, and reporting data. To improve efficiency, many clinical trial sponsors have shifted to electronic clinical outcome assessments (eCOA), including electronic patient-reported outcome (ePRO) tools.

In most cases, patients enter data using apps installed on provisioned devices. At a time when 81% of Americans own a smartphone, why not use the device they rely on every day?

Launched by MIT grads, a small start­up gets $20M to back a ro­bot­ics rev­o­lu­tion in cell ther­a­py man­u­fac­tur­ing

As co-director of an experimental cellular therapy process development and manufacturing group at UCSF specializing in T cell therapies for autoimmune conditions, Jonathan Esensten has learned a lot about the challenges involved when his group hand-fashions a cell therapy. Esensten — who was a postdoc in Wendell Lim’s lab and counts the legendary Jeffrey Bluestone as a mentor — gives them all high marks at being great at what they do, but time and again there are variations in the treatments they construct.

Af­ter be­ing goad­ed to sell the com­pa­ny, Alex­ion's CEO set some am­bi­tious new goals for in­vestors. Then Pas­cal So­ri­ot came call­ing

Back in the spring of 2020, Alexion $ALXN CEO Ludwig Hantson was under considerable pressure to perform and had been for months. Elliott Advisers had been applying some high public heat on the biotech’s numbers. And in reaching out to some major stockholders, one thread of advice came through loud and clear: Sell the company or do something dramatic to change the narrative.

In the words of the rather dry SEC filing that offers a detailed backgrounder on the buyout deal, Alexion stated: ‘During the summer and fall of 2020, Alexion also continued to engage with its stockholders, and in these interactions, several stockholders encouraged the company to explore strategic alternatives.’

Near­ly a year af­ter Au­den­tes' gene ther­a­py deaths, the tri­al con­tin­ues. What hap­pened re­mains a mys­tery

Natalie Holles was five months into her tenure as Audentes CEO and working to smooth out a $3 billion merger when the world crashed in.

Holles and her team received word on the morning of May 5 that, hours before, a patient died in a trial for their lead gene therapy. They went into triage mode, alerting the FDA, calling trial investigators to begin to understand what happened, and, the next day, writing a letter to alert the patient community so they would be the first to know. “We wanted to be as forthright and transparent as possible,” Holles told me late last month.

The brief letter noted two other patients also suffered severe reactions after receiving a high dose of the therapy and were undergoing treatment. One died a month and a half later, at which point news of the deaths became public, jolting an emergent gene therapy field and raising questions about the safety of the high doses Audentes and others were now using. The third patient died in August.

“It was deeply saddening,” Holles said. “But I was — we were — resolute and determined to understand what happened and learn from it and get back on track.”

Eleven months have now passed since the first death and the therapy, a potential cure for a rare and fatal muscle-wasting disease called X-linked myotubular myopathy, is back on track, the FDA having cleared the company to resume dosing at a lower level. Audentes itself is no more; last month, Japanese pharma giant Astellas announced it had completed working out the kinks of the $3 billion merger and had restructured and rebranded the subsidiary as Astellas Gene Therapies. Holles, having successfully steered both efforts, departed.

Still, questions about precisely what led to the deaths of the 3 boys still linger. Trial investigators released key details about the case last August and December, pointing to a biological landmine that Audentes could not have seen coming — a moment of profound medical misfortune. In an emerging field that’s promised cures for devastating diseases but also seen its share of safety setbacks, the cases provided a cautionary tale.

Audentes “contributed in a positive way by giving a painful but important example for others to look at and learn from,” Terry Flotte, dean of the UMass School of Medicine and editor of the journal Human Gene Therapy, told me. “I can’t see anything they did wrong.”

Yet some researchers say they’re still waiting on Astellas to release more data. The company has yet to publish a full paper detailing what happened, nor have they indicated that they will. In the meantime, it remains unclear what triggered the events and how to prevent them in the future.

“Since Audentes was the first one and we don’t have additional information, we’re kind of in a holding pattern, flying around, waiting to figure out how to land our vehicles,” said Jude Samulski, professor of pharmacology at UNC’s Gene Therapy Center and CSO of the gene therapy biotech AskBio, now a subsidiary of Bayer.

Anand Shah (FDA)

For­mer head of FDA’s med­ical and sci­en­tif­ic af­fairs on Covid: ‘FDA has nev­er been test­ed like this’

Anand Shah has served the American public in a unique way, crisscrossing over the last two administrations between serving as an attending radiation oncologist focused on prostate cancer at NIH, serving as CMO at the Center for Medicare and Medicaid Innovation, and most recently, leading the FDA’s operations on medical and scientific affairs from within the commissioner’s office.

Shah, who stepped down from the FDA in January, caught up with Endpoints News in a phone interview on Tuesday afternoon, offering his thoughts on the agency’s latest decision to pause the J&J vaccinations in the US, and reflecting on his time at an agency during this once-in-a-lifetime pandemic.

UP­DAT­ED: J&J paus­es vac­cine roll­out as feds probe rare cas­es of blood clots

The FDA and CDC have jointly decided to stop administering J&J’s Covid-19 vaccine after reviewing data involving six reported US cases of a rare and severe type of blood clot in individuals after receiving the vaccine.

CDC will convene a meeting of its Advisory Committee on Immunization Practices on Wednesday to further review these cases and assess their potential significance. “FDA will review that analysis as it also investigates these cases. Until that process is complete, we are recommending a pause in the use of this vaccine out of an abundance of caution,” Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research and Anne Schuchat, Principal Deputy Director of the CDC, said in a joint statement Tuesday morning.

Patrizia Cavazzoni, new CDER director

Pa­trizia Cavaz­zoni named per­ma­nent di­rec­tor of CDER, adding to ques­tions around where Wood­cock will end up

Patrizia Cavazzoni on Monday became the permanent director of the FDA’s Center for Drug Evaluation and Research, which puts to rest the idea that Janet Woodcock, Cavazzoni’s predecessor, might return to lead CDER if she isn’t made permanent commissioner.

Woodcock, who’s currently serving as acting commissioner and principal medical advisor to the commissioner, a position she was detailed to last year, may not make the move to permanent commissioner because of lingering questions from Senate Democrats. She previously served as director of CDER since 1994. Cavazzoni took over as acting director of CDER when Woodcock moved over to Operation Warp Speed to run the therapeutics side of the Trump-era program.
