Eye­ing an IPO, ADC Ther­a­peu­tics fu­els piv­otal can­cer tri­als with a $200M mega-round backed by As­traZeneca

Just days af­ter Gilead and its new sub­sidiary Kite won a ground­break­ing FDA ap­proval for their CAR-T ther­a­py Yescar­ta for B-cell lym­phomas, Lau­sanne, Switzer­land-based ADC Ther­a­peu­tics is rolling out a jaw-drop­ping $200 mil­lion mega-round to gam­ble — in part — on a next-gen an­ti­body-drug con­ju­gate that the back­ers feel can com­pete just fine with the per­son­al­ized cell ther­a­py.

The lat­est round brings ADC’s to­tal ven­ture take to $455 mil­lion, po­si­tion­ing them for a pair of Phase II stud­ies that po­ten­tial­ly could put them in line for an ac­cel­er­at­ed ap­proval — par­tic­u­lar­ly if they come close to match­ing the orig­i­nal proof-of-con­cept da­ta that was post­ed last June.

Chris Mar­tin was one of the orig­i­nal board mem­bers at ADC back in 2011 when the biotech was launched. Al­most ex­act­ly three years ago he helped arrange the sale of the UK’s Spirogen — where he was CEO — to As­traZeneca in a $440 mil­lion deal, which the phar­ma gi­ant paired with a $20 mil­lion in­vest­ment in ADC. As­traZeneca matched that in­vest­ment with an un­spec­i­fied li­cens­ing deal with ADC which is in the clin­ic. Au­ven Ther­a­peu­tics — found­ed by Stephen Evans-Freke and Pe­ter Corr in Lau­sanne — fund­ed both com­pa­nies and Mar­tin be­came the CEO at ADC two years ago.

Au­ven Ther­a­peu­tics al­so joined the ex­pand­ed syn­di­cate on this round, along­side Red­mile, the Wild fam­i­ly of­fice and As­traZeneca, among oth­er un­named in­vestors.

But ADC and Spirogen didn’t just share a com­mon fi­nan­cial pedi­gree, they al­so share a tech­nol­o­gy: pyrroloben­zo­di­azepine-based war­heads which the re­searchers be­lieve are or­ders of mag­ni­tude bet­ter than the first gen­er­a­tion of an­ti­body-drug con­ju­gates that were steered to the mar­ket by Seat­tle Ge­net­ics and oth­ers. These drugs use an an­ti­body to steer their way to can­cer cells and then drop a tox­ic pay­load where they are in­tend­ed to do the most good.

Last sum­mer, ADC backed up its new-wave boast by rolling out an ear­ly snap­shot of Phase I hu­man da­ta from its two lead ther­a­pies — AD­CT-301 and AD­CT-402.

Their 402 pro­gram tar­gets CD19, a fa­vorite in the CAR-T crowd. And re­searchers un­der CMO Jay Fein­gold, a for­mer VP of can­cer re­search at Wyeth, reg­is­tered a 57% over­all re­sponse rate, with an im­pres­sive 43% com­plete re­sponse tal­ly in drug-re­sis­tant cas­es of dif­fuse large B-cell lym­phomas. Their drug 301 came in with a 38% over­all re­sponse rate in a small group of re­frac­to­ry Hodgkin’s lym­phoma pa­tients.

Mar­tin, in his own un­der­stat­ed way, tells me: “We were en­cour­aged by that.”

ADC has been grow­ing as the cash con­tin­ues to roll in. Now 66 staffers, Mar­tin ex­pects to have a pay­roll of 70 by year’s end. On­ly 14 of those jobs are ac­tu­al­ly in Lau­sanne, the rest are scat­tered around the biotech world. The pre­clin­i­cal work is done in Lon­don, clin­i­cal de­vel­op­ment in New Jer­sey and man­u­fac­tur­ing is in San Fran­cis­co, where they’ve been work­ing with Stem­cen­trx, now a sub­sidiary of Ab­b­Vie.

Both of these mid-stage stud­ies are ex­pect­ed to get start­ed in the first half of next year, with 402 out front with a Q1 launch. Mar­tin ex­pects pa­tient re­cruit­ment to take about 6 months, with da­ta by the end of 2018 or ear­ly 2019, when they can re­view about fil­ing with the reg­u­la­to­ry agen­cies. Mar­tin isn’t promis­ing ex­act­ly when that will be, but fil­ing on Phase II in can­cer is now stan­dard op­er­at­ing pro­ce­dure in the on­col­o­gy world.

“At the mo­ment,” he says, “our over­all guid­ing prin­ci­ple is to get ef­fec­tive drugs in­to pa­tients that need it as quick­ly as pos­si­ble.”

While Yescar­ta has been post­ing im­pres­sive out­comes ahead of 402, Mar­tin doesn’t feel like they’ve been beat­en to the punch on DL­B­CL. Quite the con­trary. With a drug that can be de­liv­ered straight to pa­tients, pre­sum­ably at a low­er cost and sim­i­lar ef­fi­ca­cy, with a much safer side ef­fect pro­file, he feels the lit­tle biotech can com­pete with Gilead and its glob­al mar­ket­ing or­ga­ni­za­tion.

By next year, ADC will al­so have six ther­a­pies in the clin­ic — with two more lin­ing up INDs — open­ing up some more part­ner­ing prospects.

In the mean­time, Mar­tin is al­so qui­et­ly con­fi­dent that the com­pa­ny will be in a good po­si­tion to IPO, when the time is right. At this point, with a pri­vate syn­di­cate ready to come up with the biggest Eu­ro­pean biotech round in some three years, he says an IPO would have just proven to be a ma­jor dis­trac­tion. Un­til the right time, he says, ADC re­mains “IPO ready,” with au­dit­ed fi­nan­cials and a prospec­tus it’s keep­ing up to date as they pro­ceed.

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.
