As drug­mak­ers seek ways to elude IL-2 flaws, Clin­i­gen se­cures the full rights to orig­i­nal trou­bled IL-2 drug Pro­leukin

Pro­leukin, the trou­bled IL-2 can­cer drug sold by No­var­tis, has found a new home at Clin­i­gen, while oth­ers in the field of im­muno-on­col­o­gy seek ways to cre­ate an im­proved ver­sion of the class of drugs sans the tox­i­c­i­ty that has stymied the use of the orig­i­nal IL-2.

Last year, Lon­don-list­ed Clin­i­gen $CLIN ac­quired the rights to sell the drug out­side the Unit­ed States from No­var­tis $NVS, in a deal where fi­nan­cial de­tails were not dis­closed. The drug, which is used to treat metasta­t­ic re­nal cell car­ci­no­ma and metasta­t­ic melanoma, has gen­er­at­ed rough­ly $80 mil­lion in an­nu­al sales in the last few years, ac­cord­ing to Eval­u­ate Phar­ma. In the year lead­ing up to June 30, 2018, Pro­leukin gen­er­at­ed US sales of $60 mil­lion, ac­cord­ing to Clin­i­gen, cit­ing IQVIA es­ti­mates.

Clin­i­gen, which says it aims to re­vi­tal­ize med­i­cines of im­por­tance that have been side­lined due to chal­lenges, on Wednes­day said it is ac­quir­ing the re­main­ing US rights from No­var­tis in a deal up to $210 mil­lion in cash, in­clud­ing $120 mil­lion up­front. The rest will come in de­ferred and mile­stone pay­ments. The deal is ex­pect­ed to be con­sum­mat­ed by April.

Pro­leukin is cur­rent­ly be­ing in­ves­ti­gat­ed in some 80 ac­tive tri­als for use in a pletho­ra of dis­eases, and Clin­i­gen is “ex­plor­ing op­tions with com­pa­nies who are look­ing to cre­ate ei­ther new dosage ver­sions of (the) Il-2 or com­bi­na­tion reg­i­mens,” a spokesper­son told End­points News, de­clin­ing to elab­o­rate fur­ther on its re­vi­tal­iza­tion strat­e­gy.

The Pro­leukin ac­qui­si­tion will aug­ment Clin­i­gen’s earn­ings, adding at least 25% to its EPS in the first full fi­nan­cial year af­ter the prod­uct tran­si­tions to the com­pa­ny, and is al­so ex­pect­ed to cut its debt bur­den.

The ini­tial IL-2 ap­proach showed the promise of the tar­get, but safe­ty is­sues in­clud­ing a dose-lim­it­ing tox pro­file and im­muno­sup­pres­sion thwart­ed its po­ten­tial. Now com­pa­nies such as Nek­tar Ther­a­peu­tics $NK­TR are work­ing on a next-gen IL-2 ther­a­py, an ef­fort that com­bined with Bris­tol-My­ers’ $BMY Op­di­vo has re­cent­ly hit a snag.

Clin­i­gen al­ready owns three prod­ucts in the US: Fos­cav­ir, Ethy­ol and To­tect, al­though Pfiz­er has won the com­mer­cial li­cense to Fos­cav­ir and Cum­ber­land Phar­ma­ceu­ti­cals to Ethy­ol and To­tect.

With ad­u­canum­ab caught on a cliff, Bio­gen’s Michel Vounatsos bets bil­lions on an­oth­er high-risk neu­ro play

With its FDA pitch on the Alzheimer’s drug aducanumab hanging perilously close to disaster, Biogen is rolling the dice on a $3.1 billion deal that brings in commercial rights to one of the other spotlight neuro drugs in late-stage development — after it already failed its first Phase III.

The big biotech has turned to Sage Therapeutics for its latest deal, close to a year after the crushing failure of Sage-217, now dubbed zuranolone, in the MOUNTAIN study.

As­traZeneca, Ox­ford on the de­fen­sive as skep­tics dis­miss 70% av­er­age ef­fi­ca­cy for Covid-19 vac­cine

On the third straight Monday that the world wakes up to positive vaccine news, AstraZeneca and Oxford are declaring a new Phase III milestone in the fight against the pandemic. Not everyone is convinced they will play a big part, though.

With an average efficacy of 70%, the headline number struck analysts as less impressive than the 95% and 94.5% protection that Pfizer/BioNTech and Moderna have boasted in the past two weeks, respectively. But the British partners say they have several other bright spots going for their candidate. One of the two dosing regimens tested in Phase III showed a better profile, bringing efficacy up to 90%; the adenovirus vector-based vaccine requires minimal refrigeration, which may mean easier distribution; and AstraZeneca has pledged to sell it at a fraction of the price that the other two vaccine developers are charging.

Al­ny­lam gets the green light from the FDA for drug #3 — and CEO John Maraganore is ready to roll

Score another early win at the FDA for Alnylam.

The FDA put out word today that the agency has approved its third drug, lumasiran, for primary hyperoxaluria type 1, better known as PH1. The news comes just 4 days after the European Commission took the lead in offering a green light.

An ultra rare genetic condition, Alnylam CEO John Maraganore says there are only some 1,000 to 1,700 patients in the US and Europe at any particular point. The patients, mostly kids, suffer from an overproduction of oxalate in the liver that spurs the development of kidney stones, right through to end stage kidney disease.

Af­ter Ko­dak de­ba­cle, US lends $1.1B to a syn­thet­ic bi­ol­o­gy com­pa­ny and their big Covid-19, mR­NA plans

In mid-August, as Kodak’s $765 million government-backed push into drug manufacturing slowly fell apart in national headlines, Ginkgo Bioworks CEO Jason Kelly got a message from his company’s government liaison: HHS wanted to know if they, too, might want a loan.

The government’s decision to lend Kodak three quarters of a billion dollars raised eyebrows because Kodak had never made drugs before. But Ginkgo, while not a manufacturing company, had spent the last decade refining new ways to produce materials inside cells and building automated facilities across Boston.

Bax­ter con­tin­ues on-shoring push with $50M In­di­ana ex­pan­sion

It’s been a banner year for the once humdrum business of manufacturing drugs, particularly vaccines. Billions have been spent ramping up facilities for Covid-19 jabs, while individual CDMOs have expanded their facilities, apparently anticipating demand or responding to a government-led push to onshore drug manufacturing.

Now Baxter Biopharma Solutions, the CDMO wing of the many-armed healthcare giant Baxter, is getting in on the game. On Tuesday, they announced plans to spend $50 million to expand their flagship, 600,000 square-foot facility in Bloomington, IN.

Eu­ro­pean Union aims to es­tab­lish patent workaround in case of emer­gen­cies while try­ing to strength­en its own IP

The European Union is looking at ways to bypass patent protections and make it easier to make generic drugs in cases of emergency such as the Covid-19 pandemic, a new document says.

Normally, under WTO regulations, the practice known as “compulsory licensing” is allowed in exceptional circumstances and could be applied as a waiver to bypass patent holders. Wednesday’s document was published as part of the EU’s plan to shore up the intellectual property rights of its member states.

Pur­due Phar­ma pleads guilty in fed­er­al Oxy­Con­tin probe, for­mal­ly rec­og­niz­ing it played a part in the opi­oid cri­sis

Purdue Pharma, the producer of the prescription painkiller OxyContin, admitted Tuesday that, yes, it did contribute to America’s opioid epidemic.

The drugmaker formally pleaded guilty to three criminal charges, the AP reported, including getting in the way of the DEA’s efforts to combat the crisis, failing to prevent the painkillers from ending up on the black market and encouraging doctors to write more painkiller prescriptions through two methods: paying them in a speakers program and directing a medical records company to send them certain patient information. Purdue’s plea deal calls for $8.3 billion in criminal fines and penalties, but the company is only liable for a fraction of that total — $225 million.

PhRMA sues Trump gov­ern­ment over drug im­por­ta­tion rule — days be­fore it's set to be ef­fec­tive

Ever since President Donald Trump floated the idea of using state-sponsored importation to lower drug prices, PhRMA has made its opposition abundant. Not only is the proposal dangerous and futile,  but the trade group has also argued that it may even be illegal.

Now that the FDA has issued its final rule permitting states to bring certain drugs from Canada, PhRMA is taking the government to court — just a few days before the rule is slated to take effect.

The ad­u­canum­ab co­nun­drum: The PhI­II failed a clear reg­u­la­to­ry stan­dard, but no one is cer­tain what that means any­more at the FDA

Eighteen days ago, virtually all of the outside experts on an FDA adcomm got together to mug the agency’s Billy Dunn and the Biogen team when they presented their upbeat assessment on aducanumab. But here we are, more than 2 weeks later, and the ongoing debate over that Alzheimer’s drug’s fate continues unabated.

Instead of simply ruling out any chance of an approval, the logical conclusion based on what we heard during that session, a series of questionable approvals that preceded the controversy over the agency’s recent EUA decisions has come back to haunt the FDA, where the power of precedent is leaving an opening some experts believe can still be exploited by the big biotech.
