FDA ap­proves trail­blaz­ing post­par­tum de­pres­sion ther­a­py, in cru­cial mile­stone for wom­en's health

In a land­mark de­ci­sion, the US health reg­u­la­tor has ap­proved the first treat­ment for moth­ers suf­fer­ing from post­par­tum de­pres­sion (PPD), a com­mon but of­ten over­looked and stig­ma­tized com­pli­ca­tion of child­birth that af­fects an es­ti­mat­ed 1 in 7 women.

The man­u­fac­tur­er of the in­jectable treat­ment — Sage Ther­a­peu­tics $SAGE — has been busy, rais­ing more than half a bil­lion dol­lars through the sale of its stock to sup­port the com­mer­cial roll­out of the drug, hir­ing a 180-strong sales­force and set­ting up se­lect cen­ters for women to get ad­min­is­tered with the one-time treat­ment un­der med­ical su­per­vi­sion.

The drug brex­anolone — to be sold as Zul­res­so — was orig­i­nal­ly de­signed for at-home in­fu­sions. But that ex­pec­ta­tion was scut­tled last year, af­ter the agency and ex­perts un­der­scored con­cerns about faint­ing episodes, which oc­curred in 6 of 140 women ex­posed to brex­anolone dur­ing in­fu­sion. Still, the drug won a ring­ing en­dorse­ment by the FDA ad­vi­so­ry pan­el on the ba­sis that des­ig­nat­ed fa­cil­i­ties to mon­i­tor ad­min­is­tra­tion (en­com­pass­ing a 12-hour fol­low-up to the 60-hour in­fu­sion) would be set up. Sage ac­com­mo­dat­ed this de­mand by sub­mit­ting a fresh risk eval­u­a­tion and mit­i­ga­tion strate­gies (REMS) plan, which pushed the FDA de­ci­sion date by three months to March 19.

The treat­ment — which car­ries a boxed warn­ing high­light­ing the risk of sud­den loss of con­scious­ness — is ex­pect­ed to launch in late June, af­ter the DEA sched­ules the drug, con­sis­tent with oth­er ap­proved GABAer­gic ther­a­pies — agents that di­rect­ly mod­u­late the GA­BA sys­tem in the body or the brain.

Sage has as­signed a list price of $7,450 per Zul­res­so vial, re­sult­ing in a pro­ject­ed av­er­age course of ther­a­py cost of $34,000 per pa­tient be­fore dis­counts, a com­pa­ny spokesper­son said on Tues­day.

The drug de­vel­op­er has been con­sult­ing with “hun­dreds of pay­ers” to se­cure ac­cess, Sage’s chief busi­ness of­fi­cer Mike Cloo­nan said in an in­ter­view with End­points News ahead of the de­ci­sion.

In dis­cus­sions with phar­ma­cy ben­e­fit man­agers, the com­pa­ny feels “com­fort­able that we won’t have to re­bate a sig­nif­i­cant por­tion here, be­cause of the in­no­va­tion here we’re build­ing with Zul­res­so,” he said.

As part of its REMS strat­e­gy, the com­pa­ny is al­so work­ing on es­tab­lish­ing des­ig­nat­ed cen­ters where women can ac­cess the ther­a­py un­der med­ical su­per­vi­sion, Cloo­nan added, not­ing that “it can take months to get a site cer­ti­fied, reg­is­tered, and to es­tab­lish re­im­burse­ment path­ways.”

PPD is con­sid­ered a life-threat­en­ing con­di­tion be­cause pa­tients car­ry a risk of sui­cide, but aware­ness of the dis­or­der is patchy com­pared to oth­er ma­jor de­pres­sive con­di­tions, part­ly due to the so­cial stig­ma of be­ing la­beled an “un­hap­py moth­er” — an is­sue a grow­ing num­ber of celebri­ty moth­ers such as mod­el and cook­book au­thor Chris­sy Teigen have brought in­to the cul­tur­al zeit­geist.

PPD, which is an um­brel­la term for sev­er­al mood dis­or­ders, has pro­found neg­a­tive ef­fects on the ma­ter­nal-in­fant bond and lat­er in­fant de­vel­op­ment. Al­though a num­ber of an­ti­de­pres­sants ex­ist in the mar­ket, there is lit­tle ev­i­dence of their ef­fi­ca­cy in PPD, they usu­al­ly take 6 to 8 weeks to kick in and none are specif­i­cal­ly ap­proved for PPD.

Ac­cord­ing to Sage, rough­ly 400,000 women in the Unit­ed States suf­fer from PPD any giv­en year, al­though on­ly about half are di­ag­nosed. With Zul­res­so, the com­pa­ny ini­tial­ly plans to tar­get the se­vere PPD pop­u­la­tion, rep­re­sent­ed by about 20-30% of those 200,000 iden­ti­fied pa­tients.

Since pa­tients must be con­tin­u­ous­ly mon­i­tored by a health­care pro­fes­sion­al and ac­com­pa­nied dur­ing in­ter­ac­tions with their chil­dren when be­ing in­fused with the ther­a­py, Stifel an­a­lyst Paul Mat­teis’ fore­cast was com­par­a­tive­ly mod­est. He pro­ject­ed about $270 mil­lion in peak US sales in 2023, based on 10% pen­e­tra­tion in the se­vere PPD set­ting, with no use in mod­er­ate/mild pa­tients.

Mean­while, the com­pa­ny’s keen­ly watched oral PPD ther­a­py — SAGE-217 — is the one with big tick­et block­buster po­ten­tial, hav­ing re­cent­ly cleared a Phase III study with fly­ing col­ors. The pill — al­so be­ing eval­u­at­ed for ma­jor de­pres­sive dis­or­der (MDD) and oth­er mood dis­or­ders — ap­pears to be an im­prove­ment over brex­anolone as it is not prone to in­duc­ing the loss of con­scious­ness side ef­fect seen with the use of the in­jectable. Sage in­tends to wait for da­ta from a piv­otal study on the pill in pa­tients with ma­jor de­pres­sive dis­or­der (ex­pect­ed in 2020) be­fore sub­mit­ting a mar­ket­ing ap­pli­ca­tion.

Sage’s main ri­val is Mar­i­nus $MRNS, whose drug ganax­olone is al­so un­der eval­u­a­tion for PPD. An IV for­mu­la­tion of ganax­olone is cur­rent­ly in a Phase II study in se­vere PPD pa­tients, while mid-stage da­ta from an oral for­mu­la­tion of ganax­olone in mod­er­ate PPD pa­tients are ex­pect­ed in the first half of this year.

Zul­res­sa’s ap­proval bodes well for Mar­i­nus $MRNS, ar­gued Jef­feries’ An­drew Tsai in a re­cent note. “We think ap­proval would have a neu­tral im­pact on Mar­i­nus, de­spite Sage be­ing 2-3 years ahead, giv­en: 1) FDA ap­proval should de-risk the class/mech­a­nism broad­ly, and 2) the FDA has re­quired Sage to in­tro­duce a REMS pro­gram that lim­its its use case to a cer­ti­fied health­care fa­cil­i­ty (e.g. hos­pi­tal), which may open up an op­por­tu­ni­ty for Mar­i­nus. Sage‘s next-gen oral drug (SAGE-217) has al­so shown com­pelling ef­fi­ca­cy in Phase II/III PPD and MDD stud­ies and so far does not cause faint­ing (syn­cope) or loss of con­scious­ness (e.g. al­low­ing for home use), but our base case as­sump­tion is for the play­ers to share parts of the PPD mar­kets.”

Eli Lil­ly’s first PhI­II show­down for their $1.6B can­cer drug just flopped — what now?

When Eli Lilly plunked down $1.6 billion in cash to acquire Armo Biosciences a little more than a year ago, the stars seemed aligned in its favor. The jewel in the crown they were buying was pegilodecakin, which had cleared the proof-of-concept stage and was already in a Phase III trial for pancreatic cancer.

And that study just failed.

Lilly reported this morning that their cancer drug flopped on overall survival when added to FOLFOX (folinic acid, 5-FU, oxaliplatin), compared to FOLFOX alone among patients suffering from advanced pancreatic cancer.

Mi­rati preps its first look at their KRAS G12C con­tender, and they have to clear a high bar for suc­cess

If you’re a big KRAS G12C fan, mark your calendars for October 28 at 4:20 pm EDT.

That’s when Mirati $MRTX will unveil its first peek at the early clinical data available on MRTX849 in presentations at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics in Boston.

Mirati has been experiencing the full effect of a rival’s initial success at targeting the G12C pocket found on KRAS, offering the biotech some support on the concept they’re after — and biotech fans a race to the top. Amgen made a big splash with its first positive snapshot on lung cancer, but deflated sky-high expectations as it proved harder to find similar benefits in other types of cancers.

Sean Parker, AP

Sean Park­er helps cre­ate a CRISPRed cell ther­a­py 2.0 play — and he’s got a high-pro­file set of lead­ers on the team

You can rack up one more high-profile debut effort in the wave of activity forming around cell therapy 2.0. It’s another appealing Bay Area group that’s attracted some of the top hands in the business to a multi-year effort to create a breakthrough. And they have $85 million in hand to make that first big step to the clinic.

Today it’s Ken Drazan and the team at South San Francisco-based ArsenalBio that are coming from behind the curtain for a public bow, backed by billionaire Sean Parker and a collection of investors that includes Beth Seidenberg’s new venture investment operation based in LA.
Drazan — a J&J Innovation vet with a long record of entrepreneurial endeavors — exited the stage in 2018 when his last mission ended as he stepped aside as president of Grail. It wasn’t long, though, before he was helping out with a business plan for ArsenalBio that revolved around the work of a large group of interconnected scientists supported by the Parker Institute for Cancer Immunology.
The biotech started by putting together an “arsenal” of technologies aimed at making cell therapies for cancer much, much better than the rather crude first-generation drugs that hit the market from Novartis and Kite.
Their drugs have become the baseline against which all others are being measured.
“The technology set we’re developing is independent of the chassis,” Drazan tells me. “It doesn’t have to be autologous (extracted from the patient) or allogeneic (off the shelf). It doesn’t have to be a T cell, it could be a B cell.” But they are starting out on the autologous side, where they have the most knowledge and insight into manufacturing techniques.
It also doesn’t have to be close to the clinic.
Drazan expects the biotech will be working its way through preclinical operations for “a few years,” with enough money from the $85 million launch round to get into humans.
By today’s superheated fundraising standards, that’s not a huge amount of cash. Lyell, another cell therapy 2.0 startup we featured last week, raised $600 million in a year, including a big chunk of cash from GlaxoSmithKline. Drazan is interested in dealmaking as well, but he also knows he has the cash necessary to support the company for a good run — a key part of what it takes to bring together a stellar team of top players.

Hal Barron, GSK's president of R&D and CSO, speaks to Endpoints News founder and editor John Carroll in London at Endpoints' #UKBIO19 summit on October 8, 2019

[Video] Cel­e­brat­ing tri­al fail­ures, chang­ing the cul­ture and al­ly­ing with Cal­i­for­nia dream­ers: R&D chief Hal Bar­ron talks about a new era at GSK

Last week I had a chance to sit down with Hal Barron at Endpoints’ #UKBIO19 summit to discuss his views on R&D at GSK, a topic that has been central to his life since he took the top research post close to 2 years ago. During the conversation, Barron talked about changing the culture at GSK, a move that involves several new approaches — one of which involves celebrating their setbacks as they shift resources to the most promising programs in the pipeline. Barron also discussed his new alliances in the Bay Area — including his collaboration pact with Lyell, which we covered here — frankly assesses the pluses and minuses of the UK drug development scene, and talks about his plans for making GSK a much more effective drug developer.

UCB tries to win some re­spect in the crowd­ed pso­ri­a­sis mar­ket with a dual IL-17 ap­proach — and it won't be easy

For a pharma company with about $5 billion in revenue, a couple of respectably sized blockbuster drugs on the market and some high-profile partners like Amgen, Belgium’s UCB has kept an unusually low profile on the pipeline side of things over the years.
Until now.
Just days after striking a $2.1 billion deal to buy Ra Pharmaceuticals and its C5 rival to Soliris, UCB is posting positive top-line Phase III results for a dual IL-17 inhibitor that it’s steering into one of the most competitive commercial spaces in the industry. And despite plenty of obvious challenges as they struggle to roll out Evenity with Amgen and patent expirations loom on its franchise drugs, including Cimzia, the company just may be ready to tackle some of the biggest players on the planet.
In their first of 3 Phase III studies for bimekizumab, researchers touted top-line wins on statistically significant results on clearing plaque psoriasis, including a victory over J&J’s IL-23 contender Stelara on key endpoints. The drug targets both IL-17A and IL-17F, a modification on the IL-17A strategy laid out for Taltz (Eli Lilly) and Cosentyx (Novartis). And the new group also includes J&J’s Tremfya and AbbVie’s Skyrizi.
We don’t know the PASI90 and IGA scores — but UCB knows that with the kind of heavyweight competition it faces with Novartis and others, marginal gains for patients won’t stack up. So we’ll be watching for the hard numbers. And there’s another head-to-head with Cosentyx that will play a big role in pushing up analysts’ projections on peak sales, which currently fall well short of blockbuster status.
UCB hasn’t exactly been in the spotlight for the last few years, but it’s in a position now that the company has to win some respect in R&D, with blockbuster projects that can keep investors’ attention at a time the industry is experiencing booming R&D development efforts around the planet.
It hasn’t been easy. There was a setback on a lupus drug partnered with Biogen. But there have been some advances, with a deal to buy Proximagen’s NDA-ready nasal spray therapy USL261, designed as a rescue therapy for acute repetitive seizures, for $150 million in cash and another $220 million in sales and regulatory milestones. There was even a report that the company was kicking the deflated tires at Acorda, though nothing came of that.
Late last year UCB also committed to spend up to £200 million on a new R&D hub in the UK.
That may not translate into a lot of excitement right now, but they’re trying. And there’s a subtle promise that more deals may be in the works.

Med­ical an­i­ma­tion: Mak­ing it eas­i­er for the site and the pa­tient to un­der­stand

Medical animation has in recent years become an increasingly important tool for conveying niche information to a varied audience, particularly to those audiences without expertise in the specialist area. Science programmes today, for example, have moved from the piece-to-camera of the university professor explaining how a complex disease mechanism works, to actually showing the viewer first-hand what it might look like to shrink ourselves down to the size of an ant’s foot, and travel inside the human body to witness these processes in action. Effectively communicating a complex disease pathophysiology, or the novel mechanism of action of a new drug, can be complex. This is especially difficult when the audience domain knowledge is limited or non-existent. Medical animation can help with this communication challenge in several ways.
Improved accessibility to visualisation
Visualisation is a core component of our ability to understand a concept. Ask 10 people to visualise an apple, and each will come up with a slightly different image, some apples smaller than others, some more round, some with bites taken. Acceptable, you say, we can move on to the next part of the story. Now ask 10 people to visualise how HIV’s capsid protein gets arranged into the hexamers and pentamers that form the viral capsid that holds HIV’s genetic material. This request may pose a challenge even to someone with some virology knowledge, and it is that inability to effectively visualise what is going on that holds us back from fully understanding the rest of the story. So how does medical animation help us to overcome this visualisation challenge?

San Diego up­start de­buts dis­cov­ery en­gine that puts a twist to pro­tein degra­da­tion

For years, the idea of protein degradation — utilizing the cell’s natural garbage disposal system to mark problematic proteins for destruction — remained an elegant but technically difficult concept. But now established as a promising clinical strategy, with major biopharma players such as Bayer, Gilead and Vertex trying to grab a foothold via partnership deals, a San Diego startup is looking to exploit it and push its limits.

CSL ac­cus­es ri­val Pharm­ing of par­tic­i­pat­ing in a scheme to rip off IP on HAE while re­cruit­ing se­nior R&D staffer

Pharming has landed in the middle of a legal donnybrook after recruiting a senior executive from a rival R&D team at CSL. The Australian pharma giant slapped Pharming with a lawsuit alleging that the Dutch biotech’s new employee, Joseph Chiao, looted a large cache of proprietary documents as he hit the exit. And they want it all back.
Federal Judge Juan Sanchez in the Eastern District Pennsylvania court issued an injunction on Tuesday prohibiting Chiao from doing any work on HAE or primary immune deficiency in his new job and demanding that he return any material from CSL that he may have in his possession. And he wants Pharming to tell its employees not to ask for any information on the forbidden topics.
For its part, Pharming fired off an indignant response this morning denying any involvement in extracting any kind of IP from CSL, adding that it’s cooperating in the internal probe that CSL has underway.
