Pfiz­er boosts its gene ther­a­py work, bags up­start Bam­boo in $645M buy­out deal

Bam­boo Ther­a­peu­tics and its nascent gene ther­a­py pipeline is be­ing bought out by Pfiz­er, just five months af­ter the biotech raised close to $50 mil­lion. The phar­ma gi­ant, al­ready a mi­nor­i­ty in­vestor in Bam­boo, is pay­ing $150 mil­lion up­front for the rest of the eq­ui­ty as it sets its sights on be­com­ing a leader in gene ther­a­py de­vel­op­ment. And there’s an­oth­er $495 mil­lion in mile­stones on the ta­ble for Bam­boo’s in­vestors.

Pfiz­er had al­ready paid $43 mil­lion to buy its first stake in Bam­boo, bring­ing its to­tal bet on the com­pa­ny to up to $688 mil­lion.

Pfiz­er is land­ing a top man­u­fac­tur­ing fa­cil­i­ty for gene ther­a­pies in the deal for the UNC spin­out. It’s al­so gain­ing a pipeline of gene ther­a­pies for rare neu­ro­log­ic dis­eases, in­clud­ing Gi­ant ax­on­al neu­ropa­thy (GAN, now in Phase I/II), Cana­van dis­ease, Friedre­ich’s atax­ia and Duchenne mus­cu­lar dy­s­tro­phy.

Jude Samul­s­ki

Gene ther­a­py ex­pert Jude Samul­s­ki, who head­ed up UNC’s Gene Ther­a­py Cen­ter, will now join the phar­ma gi­ant’s ranks.

Samul­s­ki has more than 25 years ex­pe­ri­ence de­vel­op­ing AAV vec­tors for gene ther­a­pies, us­ing a be­nign virus to de­liv­er ge­net­ic ma­te­r­i­al for a po­ten­tial once-and-done fix for de­fec­tive genes that can trig­ger dis­ease.

Samul­s­ki will be join­ing a group al­ready not­ed for its chief, Michael Lin­den, who has been steadi­ly ramp­ing up work in the R&D are­na. Pfiz­er is al­so work­ing with Spark on a gene ther­a­py for he­mo­phil­ia B. And it’s col­lab­o­rat­ing with 4D Mol­e­c­u­lar Ther­a­peu­tics on car­dio reme­dies.

Gene ther­a­pies have been mak­ing a dra­mat­ic come­back in re­cent years. Blue­bird, Spark and oth­ers have been hur­ry­ing new pro­grams along and rolling out IPOs to help sup­port their work. And just a few days ago Bio­Marin added some con­sid­er­able ex­cite­ment to the field with stel­lar da­ta from a small tri­al of its he­mo­phil­ia A drug.

IM­brave150: Roche’s reg­u­la­to­ry crew plans a glob­al roll­out of Tecen­triq com­bo for liv­er can­cer as PhI­II scores a hit

Just weeks after Bristol-Myers Squibb defended its failed pivotal study pitting Opdivo against Nexavar in liver cancer, Roche says it’s beat the frontline challenge with a combination of their PD-L1 Tecentriq with Avastin. And now they’re rolling their regulatory teams in the US, Europe and China in search of a new approval — badly needed to boost a trailing franchise effort.
Given their breakthrough and Big Pharma status as well as the use of two approved drugs, FDA approval may well prove to be something of a formality. And the Chinese have been clear that they want new drugs for liver cancer, where lethal disease rates are particularly high.
Researchers at their big biotech sub, Genentech, say that the combo beat Bayer’s Nexavar on both progression-free survival as well as overall survival — the first advance in this field in more than a decade. We won’t get the breakdown in months of life gained, but it’s a big win for Roche, which has lagged far, far behind Keytruda and Opdivo, the dominant PD-1s that have captured the bulk of the checkpoint market so far.
Researchers recruited hepatocellular carcinoma — the most common form of liver cancer — patients for the IMbrave150 study who weren’t eligible for surgery ahead of any systemic treatment of the disease.
Roche has a fairly low bar to beat, with modest survival benefit for Nexavar, approved for this indication 12 years ago. But they also plan to offer a combo therapy that could have significantly less toxicity, offering patients a much easier treatment regimen.
Cowen’s Steven Scala recently sized up the importance of IMbrave150, noting:

Clay Sie­gall’s $614M wa­ger on tu­ca­tinib pays off with solid­ly pos­i­tive piv­otal da­ta and a date with the FDA

Back at the beginning of 2018, Clay Siegall snagged a cancer drug called tucatinib with a $614 million cash deal to buy Cascadian. It paid off today with a solid set of mid-stage data for HER2 positive breast cancer that will in turn serve as the pivotal win Siegall needs to seek an accelerated approval in the push for a new triplet therapy.

And if all the cards keep falling in its favor, they’ll move from 1 drug on the market to 3 in 2020, which is shaping up as a landmark year as Seattle Genetics prepares for its 23rd anniversary on July 15.
The oral TKI, designed to zero in on HER2 with a bonus for penetrating the blood brain barrier, delivered a 46% hazard ratio — reduction in risk of disease progression or death — when combined with Herceptin and Xeloda compared to the branded combo alone. That was the primary endpoint. And then two key secondaries followed, starting with a 34% reduction in risk of death alone with a p value for overall survival that hit an approval worthy p=0.0048. There was a more dramatic 52% HR among almost half of the patients who had a brain metastasis at the time of the trial, which some of the analysts see as a key to market success.
We’ll have to wait until the San Antonio Breast Cancer Symposium for the breakdown on just how many months of PFS and OS Seattle Genetics is talking about.
While the researchers were after drug resistant third-line cases in the study, where regulators are generous in allowing high levels of toxicity for dying patients, the safety profile is still key here to the drug’s competitive position on the market. By steering clear of EGFR-linked toxicity, the company is looking for a better safety profile. And while the triplet led to a 5.7% drop out rate due to adverse events, compared to 3% for the double, analysts have been scoring this one much better than Nerlynx or Tykerb.

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?

FDA ap­proval lets Foamix set its maid­en ac­ne ther­a­py on course for US mar­ket launch

Months ago, Foamix leaned on its biggest shareholders — Perceptive Advisors and OrbiMed — to financially grease its wheels, ahead of the FDA decision date for its acne therapy. On Friday, that approval came in — and the topical formulation of the antibiotic minocycline is set for a January launch.

The therapy, Amzeeq (formerly known as FMX101), was approved to treat inflammatory lesions of non-nodular moderate-to-severe acne vulgaris in patients aged 9 and older.

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.

Christine Bunt, Robert Langer. Verseau

Armed with Langer tech and $50M, Verseau hails new check­point drugs un­leash­ing macrophages against can­cer

The rising popularity of CD47 has propelled the “don’t-eat-me” signal to household name status in the immuno-oncology world: By blocking that protein, the theory goes, one can stop cancer cells from fooling macrophages. But just as PD-(L)1 merely represents the most fruitful of all checkpoints regulating T cells, Verseau Therapeutics is convinced that CD47 is one of many regulators one can modulate to stir up or tame the immune system.

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.
