Gilead shores up hope for NASH cock­tail with a glimpse at pos­i­tive proof-of-con­cept da­ta

When Gilead con­ced­ed fail­ure in its high-pro­file Phase III study for top late-stage NASH drug selon­sert­ib, CSO John McHutchi­son point­ed dis­ap­point­ed in­vestors to a com­bi­na­tion ap­proach be­ing test­ed in a mid-stage tri­al. Those da­ta are not ready just yet, but to­day the big biotech un­veiled some ear­ly num­bers to bol­ster their case for a cock­tail.

John McHutchi­son

On dis­play to­day at the In­ter­na­tion­al Liv­er Con­gress are topline re­sults from a proof-of-con­cept study test­ing cilofex­or (non­s­teroidal far­ne­soid X re­cep­tor or FXR ag­o­nist) and fir­so­co­stat (acetyl-CoA car­boxy­lase or ACC in­hibitor). Out of 20 pa­tients who were treat­ed with the oral reg­i­men once dai­ly for 12 weeks, 74% ex­pe­ri­enced “a sig­nif­i­cant de­cline of at least 30 per­cent in he­pat­ic fat” — a hall­mark of the dis­ease.

Re­searchers al­so doc­u­ment­ed im­prove­ments in oth­er bio­mark­ers, in­clud­ing “serum ALT (me­di­an rel­a­tive re­duc­tion, -37%; p<0.001) and GGT (-32%; p<0.001), along with mark­ers of re­duced bile acid syn­the­sis.”

Cilofex­or and fir­so­co­stat are al­so part of a triplet com­bo with the ASK1 in­hibitor selon­sert­ib, at the cen­ter of the Phase II AT­LAS study that McHutchi­son high­light­ed. In gen­er­al, FXR ac­ti­va­tion is thought to fight liv­er fi­bro­sis, ACC in­hibitors block fat­ty acid syn­the­sis, while ASK1 in­hibitor al­so helps re­duce in­flam­ma­tion.

“NASH is a com­plex dis­ease with mul­ti­ple bi­o­log­i­cal path­ways that in­flu­ence its pro­gres­sion. Com­bi­na­tion ther­a­peu­tic ap­proach­es which tar­get these path­ways, are like­ly to be need­ed to ef­fec­tive­ly treat pa­tients liv­ing with NASH, par­tic­u­lar­ly those with ad­vanced fi­bro­sis who have the great­est un­met need,” said McHutchi­son in a state­ment.

Gilead took a hit when selon­sert­ib flopped in its close­ly-watched STEL­LAR-4, out­per­formed by the place­bo at the low dose, though an­a­lysts ac­knowl­edged that fi­bro­sis was a tough tar­get to tack­le.

With a flock of small­er play­ers — in­clud­ing In­ter­cept, Gen­fit, Madri­gal and NGM Bio, which is part­nered with Mer­ck — con­tend­ing for the still va­cant NASH throne, Gilead has been pick­ing up ear­ly-stage as­sets in pur­suit of a sus­tain­ing fran­chise. In fact, cilofex­or came from the buy­out of Phenex Phar­ma and you might re­mem­ber fir­so­co­stat as GS-0976, which Gilead paid Nim­bus $600 mil­lion for.

It won’t be easy. But the pull is strong: NASH, which is typ­i­cal­ly as­so­ci­at­ed with obe­si­ty and di­a­betes, is set to eclipse he­pati­tis C as the lead­ing rea­son for liv­er trans­plants by 2020.

At the con­fer­ence, Gilead al­so pre­sent­ed screen­ing da­ta in sup­port of non-in­va­sive tests to iden­ti­fy NASH pa­tients with ad­vanced fi­bro­sis. Re­duc­ing the need for the cost­ly and risky liv­er biop­sies typ­i­cal­ly need­ed for the di­ag­no­sis can pave a smoother path for pa­tients to­ward treat­ment — ul­ti­mate­ly when they get ap­proved.

As FDA buck­les un­der the strain of a pan­dem­ic work­load, Trump again ac­cus­es the agency of a po­lit­i­cal hit job

Peter Marks appeared before a virtual SVB Leerink audience yesterday and said that his staff at FDA’s CBER is on the verge of working around the clock. Manufacturing inspections, policy work and sponsor communications have all been pushed down the to-do list so that they can be responsive to Covid-related interactions. And the agency’s objective right now? “To save as many lives as we can,” Marks said, likening the mortality on the current outbreak as equivalent to “a nuclear bomb on a small city.”

Play-by-play of Gilead­'s $21B Im­munomedics buy­out de­tails a fren­zied push — and mints a new biotech bil­lion­aire

Immunomedics had not really been looking for a buyout when the year began. Excited by its BLA for Trodelvy, submitted to the FDA in late 2019, executive chairman Behzad Aghazadeh started off looking for potential licensing deals and zeroed in on four potential partners, including Gilead, following January’s JP Morgan Healthcare Conference in San Francisco. Such talks advanced throughout the year, with discussions advancing to the second round in mid-August.

The win­dow is wide open as four more biotechs join the go-go IPO class of 2020

It’s another day of hauling cash in the biopharma world as four more IPOs priced Friday and a fifth filed its initial paperwork.

The biggest offering comes from PMV Pharma, an oncology biotech focusing on p53 mutations, which raised $211.8 million after pricing shares at $18 apiece. Prelude Therapeutics, developing PRMT5 inhibitors for rare cancers, was next with a $158 million raise, pricing shares at $19 each. Graybug Vision raised $90 million after pricing at $16 per share for its wet AMD candidates, and breast cancer biotech Greenwich Lifesciences brought up the rear with a small, $7 million raise after pricing shares at $5.75.

J&J of­fers PhI/IIa da­ta show­ing its sin­gle-dose vac­cine can stir up suf­fi­cient im­mune re­sponse

Days after J&J dosed the first participants of its Phase III ENSEMBLE trial, the pharma giant has detailed the early-stage data that gave them confidence in a single-dose regimen.

Testing two dose levels either as a single dose or in a two-dose schedule spaced by 56 days in, the scientists from Janssen, the J&J subsidiary developing its vaccine, reported that the low dose induced a similar immune response as the high dose. The interim Phase I/IIa results were posted in a preprint on medRxiv.

Op-ed: Will phar­ma re­al­ly pay for Trump’s lat­est law­less promise to 33 mil­lion Medicare ben­e­fi­cia­ries? Not like­ly

Sitting atop the executive branch, President Donald Trump is the ultimate authority at the FDA. He can fast track any vaccine to approval himself. If it came to that, of course.

What he can’t do is unilaterally order the legislative branch to loosen the Treasury’s coffers for $6.6 billion. Nor can he command pharmaceutical companies to pay for $200 vouchers sent to 33 million Medicare beneficiaries for prescription drugs before the election.

Pal­la­dio bags $20 mil­lion Se­ries B to top­ple a prob­lem­at­ic kid­ney dis­ease drug

Palladio Biosciences just took one step further in its quest to topple Otsuka’s Samsca with its own — it hopes safer — autosomal dominant polycystic kidney disease (ADPKD) drug.

The Pennsylvania-based biotech announced a $20 million Series B on Friday, which will fund a 10-person Phase III trial of its vasopressin V2 receptor agonist, lixivaptan. CEO Alex Martin expects to read out data in the first half of next year, then launch straight into a larger pivotal Phase III study with about 1,200 participants.

An­drew Cuo­mo says New York will un­der­take its own vac­cine re­view process, and wouldn’t rec­om­mend trust­ing the fed­er­al gov­ern­ment

The concerns keep mounting over President Donald Trump’s politicization of the FDA and other federal agencies guiding the development of a safe and effective vaccine. And today, the telegenic New York governor Andrew Cuomo appeared to introduce even more politics into the matter — latest in an ongoing series of incidents that have cast the proudly independent FDA in starkly political terms.

During his daily press conference Cuomo said that the state will review any coronavirus vaccines approved by the federal government, citing a lack of trust in the Trump administration. The announcement comes one day after Trump accused the FDA of making an “extremely political” move in proposing stricter vaccine guidance.

Laura Shawver (Silverback Therapeutics)

Fol­low­ing a hefty Se­ries B, Sil­ver­back Ther­a­peu­tics quick­ly pulls in $85M for 'an im­por­tant growth phase'

Months after reeling in a $78 million Series B round, Silverback Therapeutics has hooked an even larger Series C.

The Seattle-based company announced Wednesday that it netted $85 million from a slate of new and previous investors. The quick boost could be a sign that an IPO is on the way.

In an email, Silverback CEO Laura Shawver told me she was “not able to provide any additional comments about Silverback” beyond what was shared in the company’s news release. In the prepared statement, she said the company is at “an important growth phase.”
