Gilead los­es key patent claims for So­val­di in Chi­na, open­ing door to ear­li­er gener­ic en­try

A par­tial patent in­val­i­da­tion by Chi­nese au­thor­i­ties has shak­en the case Gilead has been build­ing for its hep C star So­val­di by re­mov­ing a key bar­ri­er to gener­ic en­try.

The de­ci­sion means knock­offs of the high­ly ef­fec­tive hep C treat­ment can ar­rive as ear­ly as next year — rather than 2024, when the patent was orig­i­nal­ly set to ex­pire — ac­cord­ing to the Ini­tia­tive for Med­i­cines, Ac­cess, and Knowl­edge, or I-MAK. I-MAK filed one of the two re­quests for patent in­val­i­da­tion cit­ed in the rul­ing, to­geth­er with Chi­nese drug­mak­er Fu­jian Co­sunter Phar­ma.

Be­cause the patent con­cerns so­fos­bu­vir, a cru­cial base com­pound that’s al­so used to make com­bo drugs like Har­voni and Ep­clusa, this de­ci­sion could af­fect not just one prod­uct but Gilead’s whole hep C fran­chise in the coun­try.

In re­sponse to my ques­tion as to whether Gilead will ap­peal the rul­ing (they have three months to do so), a spokesper­son says the Fos­ter City, CA-based com­pa­ny has not with­drawn their claims to the so­fos­bu­vir com­pound patent ap­pli­ca­tion in Chi­na. Here’s the rest of the re­sponse:

This patent ap­pli­ca­tion is cur­rent­ly be­ing re­viewed by the Patent Re­view Board (PRB). Last week Chi­na’s PRB con­firmed the va­lid­i­ty of claims cov­er­ing the SOF metabo­lites. This de­ci­sion has no im­pact on our SOF com­pound patent ap­pli­ca­tion. Gilead is con­fi­dent in the in­tel­lec­tu­al prop­er­ty cov­er­ing the so­fos­bu­vir com­pound and all its he­pati­tis C med­i­cines, which bring the po­ten­tial of a cure to the vast ma­jor­i­ty of pa­tients suf­fer­ing from chron­ic he­pati­tis C virus (HCV) in­fec­tion. In the mean­time, we will con­tin­ue to work with the Chi­nese gov­ern­ment to fa­cil­i­tate broad ac­cess to Gilead’s he­pati­tis C med­i­cines.

While So­val­di was launched in Chi­na at one-fifth the con­tem­po­rary price in the US — al­most $9,000 for a 12-week regime — its price still fre­quent­ly comes un­der at­tack, as it has in many oth­er coun­tries around the world. In fact, Gilead has drawn crit­i­cism ever since it be­gan sell­ing the drug at $84,000 in the US. And where­as Gilead de­signed li­cens­ing deals with gener­ic com­pa­nies in coun­tries like Ukraine, Be­larus, Thai­land and Malaysia in re­sponse to com­plaints, no such agree­ment was struck in Chi­na.

Back in 2015, two years be­fore So­val­di would be ap­proved in Chi­na, the au­thor­i­ties had re­ject­ed Gilead’s ap­pli­ca­tion for an in­ac­tive pro­drug that is me­tab­o­lized once in the body.

I-MAK, which al­so played a role in that de­ci­sion, has been bring­ing le­gal chal­lenges against Gilead in a num­ber of oth­er coun­tries, in­clud­ing the US. Its co-founder Tahir Amin told STAT that even though Gilead still holds four re­main­ing patent claims on So­val­di and da­ta ex­clu­siv­i­ty in Chi­na, they shouldn’t hin­der gener­ic mak­ers as much as this patent had.

Co­sunter, which mar­ket­ed Chi­na’s first hep B gener­ic, is said to be de­vel­op­ing a copy­cat ver­sion of So­val­di.

How Pa­tients with Epilep­sy Ben­e­fit from Re­al-World Da­ta

Real-world data (RWD) has the potential to transform the drug development industry’s efforts to predict and treat seizures for patients with epilepsy. Anticipating or controlling an impending seizure can significantly increase quality of life for patients with epilepsy. However, because RWD is secondary data originally collected for other purposes, the challenge is selecting, harmonizing, and analyzing the data from multiple sources in a way that helps support patients.

UP­DAT­ED: Gink­go Bioworks re­sizes the de­f­i­n­i­tion of go­ing big in biotech, rais­ing $2.5B in a record SPAC deal that weighs in with a whop­ping $15B-plus val­u­a­tion

Ginkgo Bioworks execs always thought big. But today should redefine just how big an upstart biotech player can dream.

In the largest SPAC deal to clear the hurdles to Nasdaq, the biotech that envisioned everything from remaking synthetic meat to a whole new approach to developing drugs has joined forces with one of the biggest disruptors in biotech to slam the Richter scale on dealmaking.

Soon after becoming the darling of the VC crew and clearing the bar on a $4 billion valuation, Ginkgo — a synthetic biotech player out to reprogram cells with industrial efficiency — has now struck a deal to go public in the latest leviathan SPAC that sets its pre-money valuation at $15 billion. In one swift vault, Ginkgo will combine with Harry Sloan’s Soaring Eagle Acquisition Corp. and leap into the public markets.

FDA un­veils six ICH guide­lines ahead of meet­ing with Health Cana­da

A sign that the FDA’s non-Covid-related processes are beginning to normalize: The release of six guidelines from the International Council of Harmonisation.

Years in development, the ICH documents offer an international perspective on drug development, with these latest guidelines covering everything from recommendations to support the classification of drug substances, featured in the M9 guidance, to standards for nonclinical safety studies for pediatric medicines in the S11 guideline.

Sanofi, Glax­o­SmithK­line, Boehringer ac­cused of play­ing games, de­stroy­ing emails re­lat­ed to law­suit over con­t­a­m­i­nat­ed Zan­tac

A recent court filing raises new questions about how major pharma companies like Sanofi, GlaxoSmithKline, and Boehringer Ingelheim have dealt with a lawsuit related to recalls of certain over-the-counter heartburn drugs due to the presence of a potentially cancer-causing substance found in them.

More than 70,000 people who took Sanofi’s Zantac and other heartburn drugs containing ranitidine, which have been recalled over the past two years, have sued the manufacturers, including generic drugmakers, and other retailers and distributors as part of a consolidated suit before US District Court Judge Robin Rosenberg in Florida.

Per­cep­tive Ad­vi­sors, Xon­toge­ny bring the band back and then some with a $515M sec­ond fund sniff­ing out lead com­pounds

When Perceptive Advisors and startup accelerator Xontogeny initially teamed up on an early-stage VC round in 2019, the partners hoped to prove their investments could be a force multiplier for early-stage companies. Now, with that proof of concept behind them, the pair have closed a second VC round worth more than double the money.

Dubbed PXV Fund II and headed by Xontogeny CEO and former Sarepta head Chris Garabedian, the $515 million fund will target 10 to 12 early-stage preclinical companies with Series A rounds in the $20 million to $40 million range with opportunities for Series B follow-ups. The oversubscribed fund is bringing the band back with initial investors from PXVI as well as new investors that include “top-tier” asset managers, endowments, foundations, family offices, and individual investors.

A clos­er look at the FDA’s more than 700 pan­dem­ic-re­lat­ed record re­quests to re­place on­site in­spec­tions

As the pandemic constrained the FDA’s ability to travel for onsite manufacturing inspections, the agency increasingly turned to requesting records to fill the gap, even for hundreds of US-based facilities.

FDA explains in its guidance on manufacturing inspections during the pandemic that the agency can request records (not to be confused with the FDA’s remote interactive evaluations) directly from facilities “in advance of or in lieu of” certain onsite inspections. Companies are legally required to fulfill those requests because a denial may be considered limiting an inspection, which could lead to the FDA deeming a drug made at that site to be adulterated.

Stephen Squinto, Gennao Bio CEO (Gennao)

Alex­ion co-founder Stephen Squin­to is back in the game as CEO, this time for a small gene ther­a­py play­er

With his name already behind a rare disease success story in Alexion, Stephen Squinto was looking for a great story to drive him to jump back into the biotech game. He found that in a fledging non-viral gene therapy company, and now he’s got a few backers on board as well.

On Tuesday, Gennao Bio launched with a $40 million Series A co-led by OrbiMed and Logos Capital with participation by Surveyor Capital. The biotech, which is looking to use its cell-penetrating antibody platform to deliver nucleic acid “payloads” during into the nucleus, had to rush for its initial series — and had a name change along the way.

Alvotech takes Ab­b­Vie to court over al­leged patent 'mine­field' sur­round­ing megablock­buster Hu­mi­ra

AbbVie has so far been successful in shooing away competition to its megablockbuster Humira, deploying a number of patents and settlements to keep biosimilars off the US market until 2023. But one Icelandic drugmaker doesn’t want to wait — and on Tuesday, it filed a lawsuit challenging what it called a patent “minefield.”

Alvotech has accused AbbVie of trying to “overwhelm” and “intimidate” it with “an outrageous number of patents of dubious validity,” according to court documents. The company is currently seeking approval for its Humira copycat AVT02, which AbbVie says would infringe upon 62 patents.

UP­DAT­ED: Feds charge an­oth­er CRO staffer with fak­ing da­ta in a Glax­o­SmithK­line pe­di­atric asth­ma study

A Florida woman has been indicted as part of a clinical trial fraud scheme over a GlaxoSmithKline pediatric asthma study, the Justice Department announced Tuesday, the latest development in a case where three individuals have already pleaded guilty.

Jessica Palacio was charged with participating in a plot to falsify medical records, giving off the appearance that trial participants were making their scheduled visits to a Miami CRO and taking an experimental asthma medication as required. Palacio was also charged with lying to FDA investigators about her conduct.
