As­traZeneca, Am­gen roll up a 'break­through' at the FDA in hot pur­suit of a po­ten­tial game chang­er in asth­ma

By this point, the nov­el­ty of the FDA’s break­through ther­a­py des­ig­na­tion has large­ly been worn away by a drum­beat of an­nounce­ments for new ad­di­tions to the pro­gram. But As­traZeneca and Am­gen just land­ed one that de­serves a clos­er look.

Bahi­ja Jal­lal

Reg­u­la­tors have hand­ed the big league part­ners VIP sta­tus for a se­vere asth­ma drug called teze­pelum­ab. As al­ways, BTD gives them ready ac­cess to FDA in­sid­ers who are now pledged to help push this through to a speedy con­clu­sion. And we know now that that promise is worth some­thing.

What makes this drug a stand­out is its abil­i­ty to tar­get thymic stro­mal lym­phopoi­etin — TSLP – an up­stream mod­u­la­tor of mul­ti­ple in­flam­ma­to­ry path­ways like IL-4, IL-5 and IL-13.

In a Phase IIb read­out, treat­ment-re­sis­tant pa­tients demon­strat­ed re­duc­tions of 61% to 71% in their an­nu­al ex­ac­er­ba­tion rate. And that has ex­ecs at both of the phar­ma com­pa­nies stoked that this drug could be worth bil­lions if it reach­es the mar­ket.

Bahi­ja Jal­lal, who runs As­traZeneca’s big sub­sidiary Med­Im­mune, has called the re­sults “un­prece­dent­ed,” and Leerink’s Sea­mus Fer­nan­dez pegged peak po­ten­tial sales at $4.5 bil­lion. That could ar­rive soon­er than lat­er, he added, de­pend­ing on the FDA’s will­ing­ness to let this study stand as a reg­is­tra­tional land­mark that would al­low for a con­fir­ma­to­ry Phase III to of­fer enough ev­i­dence wor­thy of ap­proval.

Asth­ma, though, is not can­cer. Late-stage pro­grams in the field of­ten run in­to years. And there’s no fi­nal word from the com­pa­nies on their Phase III pro­gram, or whether reg­u­la­tors will need to see da­ta from dose-rang­ing stud­ies be­fore they give their de­ci­sion. But the de­vel­op­ers’ chances of be­ing put on the in­side track just got bet­ter.

Both Am­gen and As­traZeneca — which has been stag­ger­ing through a set of fresh set­backs out­side of the on­col­o­gy group — could use a big OK. And while there are no guar­an­tees that reg­u­la­tors will play along here, they just took an im­por­tant step for­ward along the road to a po­ten­tial block­buster OK.

Grow­ing ac­cep­tance of ac­cel­er­at­ed path­ways for nov­el treat­ments: but does reg­u­la­to­ry ap­proval lead to com­mer­cial suc­cess?

By Mwango Kashoki, MD, MPH, Vice President-Technical, and Richard Macaulay, Senior Director, of Parexel Regulatory & Access

In recent years, we’ve seen a significant uptake in the use of regulatory options by companies looking to accelerate the journey of life-saving drugs to market. In 2018, 73% of the novel drugs approved by the U.S. Federal Drug Administration (FDA) were designated under one or more expedited development program categories (Fast Track, Breakthrough Therapy, Priority Review, and Accelerated Approval).ᶦ

Sanofi out­lines big API plans as coro­n­avirus out­break re­port­ed­ly threat­ens short­age of 150 drugs

As the world becomes increasingly dependant on Asia for the ingredients of its medicines, Sanofi sees business to be done in Europe.

The French drugmaker said it’s creating the world’s second largest active pharmaceutical ingredients (API) manufacturer by spinning out its six current sites into a standalone company: Brindisi (Italy), Frankfurt Chemistry (Germany), Haverhill (UK), St Aubin les Elbeuf (France), Újpest (Hungary) and Vertolaye (France). They have mapped out €1 billion in expected sales by 2022 and 3,100 employees for the new operations headquartered in France.

UP­DAT­ED: NGM Bio takes leap for­ward in crowd­ed NASH field

South San Francisco-based NGM Bio may have underwhelmed with its interim analysis of a key cohort from a mid-stage NASH study last fall — but stellar topline data unveiled on Monday showed the compound induced significant signs of antifibrotic activity, NASH resolution and liver fat reduction, sending the company’s stock soaring.

There are an estimated 50+ companies focused on developing drugs for non-alcoholic steatohepatitis, or NASH, a common liver disease that has long flummoxed researchers. The first wave of NASH drug developers struggled with efficacy as well as safety — and companies big and small have crashed and burned.

Soft­Bank's newest, $165M biotech in­vest­ment looks for in­fec­tious traces in the blood

SoftBank has found its newest biotech investment.

The Japanese bank has invested $165 million into Karius, a company that uses blood tests to diagnose infectious diseases, as part of its new Vision Fund 2. The full scope of the new fund has yet to be announced, but the first and newly-beleaguered Vision Fund poured $100 billion into technology companies, including the biotechs Vir Biotechnology and Roivant and the sequencing company 10x Genomics.

FDA grants ‘break­through’ sta­tus to an­tibi­ot­ic al­ter­na­tive as Con­tra­Fect rush­es to join fight against su­per­bug

An experimental drug that promises to be the first anti-infective agent to prove superior to vancomycin — an antibiotic approved in 1958 — has notched the FDA’s “breakthrough” status.

ContraFect said the designation was based on Phase II data in which exebacase was tested against a superbug known as methicillin-resistant Staph aureus, or MRSA. In a subgroup analysis, the clinical responder rate at day 14 was 42.8% higher than that among those treated with standard of care, the company said (p=0.010).

Har­vard joins coro­n­avirus fight with $115 mil­lion and a high-pro­file Chi­nese part­ner

For two months, as the novel coronavirus swelled from a few early cases tied to a Wuhan market to a global epidemic, most of the world’s focus and dollars have flowed toward emergency initiatives: building vaccines at a record pace, plucking experimental antivirals out of freezers to see what sticks and immunizing mice for new antibodies.

Now a new and well-funded collaboration between Harvard and a top Chinese research institute will play the long game. In a 5-year, $115 million initiative backed by China Evergrande Group, researchers from the Harvard Medical School, Harvard T.H. Chan School of Public Health and Guangzhou Institute for Respiratory Health will study the virus in an effort to develop therapies against infections by the novel coronavirus, known as SARS–CoV-2, and to prevent new ones.

No­var­tis gets a boost in block­buster mul­ti­ple scle­ro­sis race with Roche

In the first step of what’s likely to be a long and uphill battle for the drugmaker, the FDA has accepted Novartis’s BLA submission for a new multiple sclerosis drug and given it priority review. The PDUFA date for the potential blockbuster drug is in June.

An­i­mal health vet Juer­gen Horn makes new an­ti­body play for pets, rak­ing $15M in Se­ries A haul

Zoetis forked over $85 million in 2017 to acquire Nexvet Biopharma and its pipeline of monoclonal antibodies. Juergen Horn, Nexvet’s former chief product development officer, has now secured $15 million for his own biologic company for animals: Invetx.

Buoyed by emerging advances in gene therapies for humans, scientists have started looking at harnessing the technology for animals setting up companies such as Penn-partnered Scout Bio and George Church-founded Rejuvenate Bio. But akin to Nexvet, Invetx is working on leveraging the time-tested science of monoclonal antibodies to treat chronic diseases that afflict man’s best friend.

As coro­n­avirus out­break reach­es 'tip­ping point,' GSK lends ad­ju­vant tech to Chi­nese part­ner armed with pre­clin­i­cal vac­cine

As the coronavirus originating out of Wuhan spreads to South Korea, Italy and Iran, stoking already intense fears of a pandemic, GlaxoSmithKline has found another pair of trusted hands to place its adjuvant system. China’s Clover Biopharmaceuticals will add the adjuvant to its preclinical, protein-based vaccine candidate against SARS-CoV-2.

Clover, which is based in the inland city of Chengdu, boasts of a platform dubbed Trimer-Tag that produces covalently-trimerized fusion proteins. Its candidate, COVID-19 S-Trimer, resembles the viral spike (S)-protein found in the virus.
