Two years on, Al­ler­gan’s $1.7B NASH drug still looks weak — at best

Five months af­ter No­var­tis stepped up to col­lab­o­rate with Al­ler­gan on a com­bo NASH pro­gram, Al­ler­gan $AGN has fol­lowed up with what it de­scribes as an en­cour­ag­ing fol­lowup snap­shot to the mid-stage da­ta for their drug ceni­crivi­roc.

But that could take some ex­plain­ing.

Their drug — which flat failed the pri­ma­ry and one sec­ondary in the Phase IIb — un­sur­pris­ing­ly missed the com­pos­ite end­point look­ing at a one-stage drop in pa­tients’ dis­ease score with symp­toms sta­bi­liz­ing.

Af­ter two years of treat­ment, there was no sig­nif­i­cant sep­a­ra­tion be­tween the drug and the place­bo.

In what looks more like a base hit at best, Al­ler­gan says the lat­est up­date from the Phase IIb tri­al al­so shows that 20% of the place­bo pa­tients who crossed over to the drug arm in year 2 hit the com­bined pri­ma­ry end­point with a min­i­mum one-stage drop in their dis­ease score with no wors­en­ing of symp­toms. The place­bo arm rate was 13%.

If you look just at the one-stage drop end­point, the break­out was a more en­cour­ag­ing 35% com­pared to 20%. And re­searchers tout­ed a bet­ter score among pa­tients with high lev­els of fi­bro­sis with plans to pur­sue some ad­di­tion­al analy­sis to see how best to po­si­tion this drug.

These kind of mixed da­ta on this drug is not what Al­ler­gan’s back­ers want to see at this point. But the ex­ec crew says they are ea­ger­ly pur­su­ing the Phase III, re­cruit­ing 2,000 pa­tients with a one-year end­point they be­lieve they can hit. And R&D chief David Nichol­son says any weak­ness in the new Phase IIb up­date was due to miss­ing da­ta and an unan­tic­i­pat­ed place­bo re­sponse — none of which is dulling his en­thu­si­asm for Phase III.

In a state­ment to End­points News, he not­ed:

“The da­ta we have ac­cu­mu­lat­ed con­vinces both Al­ler­gan, as well as our ex­ter­nal ex­perts, that CVC has an­tifi­brot­ic ac­tiv­i­ty in pa­tients suf­fer­ing from NASH. Our phase 2 CEN­TAUR study has twice and in­de­pen­dent­ly shown a re­duc­tion in fi­bro­sis fol­low­ing 1 year of treat­ment. This an­tifi­brot­ic ac­tiv­i­ty is most promi­nent in se­vere­ly ill pa­tients, and un­like place­bo treat­ed pa­tients, it was durable in the ma­jor­i­ty of pa­tients re­ceiv­ing CVC. The stud­ies per­formed to date in­di­cate that CVC can be safe­ly ad­min­is­tered to NASH pa­tients. As it re­lates to the year two da­ta, the re­sults were con­found­ed by miss­ing da­ta, and high­er than ex­pect­ed place­bo rates, name­ly in pa­tients with ear­ly stage dis­ease; this was not unan­tic­i­pat­ed. Larg­er Phase 3 stud­ies are now need­ed, as al­ways, to con­firm the ef­fi­ca­cy and safe­ty pro­file sug­gest­ed by our phase 2 da­ta.”

Al­ler­gan agreed to pay up to $1.7 bil­lion to buy this drug in their ac­qui­si­tion of To­bi­ra last fall, a 6x pre­mi­um that sur­prised quite a few an­a­lysts af­ter the biotech saw its Phase IIb study flop and its share price was crushed. The drug hit one of the sec­on­daries, though, which en­cour­aged Al­ler­gan to step in.

AveX­is sci­en­tif­ic founder fires back at No­var­tis CEO Vas Narasimhan, 'cat­e­gor­i­cal­ly de­nies any wrong­do­ing'

Brian Kaspar’s head was among the first to roll at Novartis after company execs became aware of the fact that manipulated data had been included in its application for Zolgensma, now the world’s most expensive therapy.

But in his first public response, the scientific founder at AveXis — acquired by Novartis for $8.7 billion — is firing back. And he says that not only was he not involved in any wrongdoing, he’s ready to defend his name as needed.

I reached out to Brian Kaspar after Novartis put out word that he and his brother Allen had been axed in mid-May, two months after the company became aware of the allegations related to manipulated data. His response came back through his attorneys.

UP­DAT­ED: An em­bold­ened As­traZeneca splurges $95M on a pri­or­i­ty re­view vouch­er. Where do they need the FDA to hus­tle up?

AstraZeneca is in a hurry.

We learned this morning that the pharma giant — not known as a big spender, until recently — forked over $95 million to get its hands on a priority review voucher from Sobi, otherwise known as Swedish Orphan Biovitrum.

That marks another step down on price for a PRV, which allows the holder to slash 4 months off of any FDA review time.

Pris­on­er #87850-053 does not get to add drug de­vel­op­er to his list of cred­its

Just days after Retrophin shed its last ties to founder Martin Shkreli, the biotech is reporting that the lead drug he co-invented flopped in a pivotal trial. Fosmetpantotenate flunked both the primary and key secondary endpoints in a placebo-controlled trial for a rare disease called pantothenate kinase-associated neurodegeneration, or PKAN.

We­bi­nar: Re­al World End­points — the brave new world com­ing in build­ing fran­chise ther­a­pies

Several biopharma companies have been working on expanding drug labels through the use of real world endpoints, combing through the data to find evidence of a drug’s efficacy for particular indications. But we’ve just begun. Real World Evidence is becoming an important part of every clinical development plan, in the soup-through-nuts approach used in building franchises.

I’ve recruited a panel of 3 top experts in the field — the first in a series of premium webinars — to look at the practical realities governing what can be done today, and where this is headed over the next few years, at the prodding of the FDA.

ZHEN SU — Merck Serono’s Senior Vice President and Global Head of Oncology
ELLIOTT LEVY — Amgen’s Senior Vice President of Global Development
CHRIS BOSHOFF — Pfizer Oncology’s Chief Development Officer

Am­gen, Al­ler­gan biosim­i­lar of Roche's block­buster Rit­ux­an clears an­oth­er US piv­otal study 

Novartis $NVS may have given up, but Amgen $AMGN and Allergan $AGN are plowing ahead with their knockoff of Roche’s blockbuster biologic Rituxan in the United States.

Their copycat, ABP 798, was found to have a clinically equivalent impact as Rituxan — meeting the main goal of the study involving CD20-positive B-cell non-Hodgkin’s lymphoma patients. This is the second trial supporting the profile of the biosimilar. In January, it came through with positive PK results in patients with rheumatoid arthritis.

BeiGene and Mus­tang nail down spe­cial FDA sta­tus for top drugs; Roche bags added cov­er­age for Hem­li­bra

→ BeiGene $BGNE is getting a boost in its drive to field a rival to Imbruvica. The FDA has offered an accelerated review to zanubrutinib, a BTK inhibitor that has posted positive results for mantle cell lymphoma. The PDUFA date lands on February 27, 2020. The drug scored breakthrough status at the beginning of the year.

→ BeiGene isn’t the only biopharma company to gain special regulatory status today. Mustang Bio $MBIO and St. Jude Children’s Research Hospital announced that MB-107, a lentiviral gene therapy for the treatment of X-linked severe combined immunodeficiency, also known as bubble boy disease, has been granted Regenerative Medicine Advanced Therapy status.

Trump ad­min­is­tra­tion re­vives bid to get drug list prices on TV ads

The Trump administration is not giving up just yet. On Wednesday, the HHS filed an appeal against a judge’s decision in July to overturn a ruling obligating drug manufacturers to disclose the list price of their therapies in television adverts — hours before it was stipulated to go into effect.

In May, the HHS published a final ruling requiring drugmakers to divulge the wholesale acquisition cost— of a 30-day supply of the drug — in tv ads in a bid to enhance price transparency in the United States. The pharmaceutical industry has vehemently opposed the rule, asserting that list prices are not what a typical patient in the United States pays for treatment — that number is typically determined by the type of (or lack thereof) insurance coverage, deductibles and out-of-pocket costs. Although there is truth to that claim, the move was considered symbolic in the Trump administration’s healthcare agenda to hold drugmakers accountable in a climate where skyrocketing drug prices have incensed Americans on both sides of the aisle.

Ver­sant-backed Chi­nook gets a $65M launch round for its dis­cov­ery quest in a resur­gent kid­ney field

Versant is once again stepping off the beaten track in biotech to see if they can blaze a trail of their own in a field that has looked too thorny to many investors for years.

The venture group and their partners at Apple Tree are bringing their latest creation out of stealth mode today. Born in Versant’s Inception Sciences’ Chinook Therapeutics is betting that its preclinical take on kidney disease can get an early lead among the companies starting up in the field.

Sir An­drew Dil­lon, NICE's first — and on­ly — chief ex­ec­u­tive to step down next year

Using a laptop borrowed from his former employer, South London’s St George’s Hospital, Sir Andrew Dillon set about establishing NICE — launched by the then health secretary Frank Dobson — in 1999.  On Thursday, the UK cost-effectiveness watchdog said its first and only chief executive — Dillon — is stepping down in March 2020.

Back in the day, decisions about which drugs and interventions were funded by the National Health Service (NHS) were made at the local level, but this ‘postcode prescribing’ system was fraught with skewed healthcare deployment making the structure unsustainable. A national system was deemed necessary — and NICE was formed to bridge that gap.
