One of Af­fimed’s new glass slip­pers cracks as a dead­ly in­ci­dent forces halt to PhI can­cer tri­als

Af­fimed’s Cin­derel­la sto­ry has tak­en a dead­ly twist.

Just a few weeks af­ter sign­ing Genen­tech on to the plat­form for a col­lab­o­ra­tion us­ing its NK cell tech for guid­ing an im­mune re­sponse against can­cer, re­searchers for the biotech $AFMD have waved back pa­tients in a Phase I pro­gram for their CD19/CD3-tar­get­ing T cell en­gager AFM11 af­ter the death of one pa­tient and a life-threat­en­ing re­ac­tion in two oth­ers.

The Phase I ef­fort cov­ers two types of can­cer: CD19 pos­i­tive B-cell non-Hodgkin lym­phoma and acute lym­phoblas­tic leukemia. Now the biotech has put the tri­als on hold and Af­fimed ex­ecs say they’ve in­formed reg­u­la­tors as they in­ves­ti­gate what went wrong.

Its shares tanked, plung­ing 30% on the news.

Adi Hoess, Af­fimed CEO

There’s no word in the com­pa­ny’s state­ment what the re­ac­tion was, just that the three pa­tients were on the high dose of a drug that tar­gets CD3. Their more ad­vanced work on an NK cell en­gage­ment strat­e­gy will pro­ceed.

Af­fimed has been on a roller coast­er ride over the last few months. Its stock was beat­en up dur­ing the Eu­ro­pean Hema­tol­ogy As­so­ci­a­tion meet­ing in June as the com­pa­ny of­fered up an ear­ly look at pos­i­tive re­spons­es in their ear­ly study of AFM13, its lead NK cell en­gager can­di­date. 

Then, when Genen­tech stepped up with $96 mil­lion up­front and bil­lions in po­ten­tial mile­stones, the biotech world took a clos­er look at the NK tech that the big Roche sub­sidiary was most in­ter­est­ed in — and the stock soared.

That deal com­bined Genen­tech’s deep ex­pe­ri­ence with tu­mor bi­ol­o­gy with the biotech’s own know-how in ac­ti­vat­ing NK cells while us­ing a plat­form tech that the CEO de­scribed as a “sim­pli­fied en­gi­neer­ing sys­tem” that can cre­ate new ther­a­peu­tics with­out the need for adding a lot of staff. The plat­form spe­cial­izes in “tetrava­lent, mul­ti-spe­cif­ic im­mune cell en­gagers,” with an an­ti­body ap­proach that ap­plies to a va­ri­ety of dis­ease set­tings, bring­ing in the tu­mor cell killers need­ed to di­rect­ly en­gage can­cer.

A num­ber of pa­tients have been killed in tri­als dur­ing the last few years, most no­tably at Juno, which had to scrap its lead CAR-T and drop out of the race for the first ap­proval in the field af­ter a se­ries of dead­ly in­ci­dents. 

The com­pa­ny, now a sub­sidiary of Cel­gene, as well as for­mer CEO Hans Bish­op, re­cent­ly signed off on a $24 mil­lion pay­ment to the stock­hold­ers who brought a class ac­tion suit against the biotech based on their claims that the com­pa­ny had mis­led in­vestors by con­ceal­ing the death of the first pa­tient. 

That amounts to a speed­ing tick­et af­ter Cel­gene paid $9 bil­lion for the group, which is now pur­su­ing a new, safer lead pro­gram.

UP­DAT­ED: In a stun­ning turn­around, Bio­gen says that ad­u­canum­ab does work for Alzheimer's — but da­ta min­ing in­cites con­tro­ver­sy and ques­tions

Biogen has confounded the biotech world one more time.

In a stunning about-face, the company and its partners at Eisai say that a new analysis of a larger dataset on aducanumab has restored its faith in the drug as a game-changer for Alzheimer’s and, after talking it over with the FDA, they’ll now be filing for an approval of a drug that had been given up for dead.

UP­DAT­ED: Failed PhI­II fe­vip­iprant tri­als pour more cold wa­ter on No­var­tis' block­buster R&D en­gine — and briefly spread the chill to a high-pro­file biotech

Back in July, during an investor call where Novartis execs ran through an upbeat assessment of their Q2 performance, CEO Vas Narasimhan and development chief John Tsai were pressed to predict which of the two looming Phase III readouts — involving cardio drug Entresto and asthma therapy fevipiprant, respectively — had a higher likelihood of success. Tsai gave the PARAGON-HF study with Entresto minimally better odds, but Narasimhan emphasized that their strategy of giving fevipiprant to more severe patients gave them confidence.

David Liu un­veils newest ad­vance­ment in CRISPR tech: Prime edit­ing

The researcher behind base-editing is out with what some scientists are hailing as the biggest advancement in CRISPR technology since that 2016 breakthrough: “prime editing.” The new molecular gadget is capable of erasing any base pair and stenciling in another and cutting or adding long segments of DNA without breaking both strands of the helix.

David Liu, base editing pioneer and founder of Beam Therapeutics, published the findings in Nature alongside Andrew Anzalone. They estimated that the breakthrough “in principle” puts 89% of human diseases in purview — although experts cautioned that human therapies were a long way off.

Fra­zier Health­care Part­ner­s' der­ma­tol­ogy up­start at­tracts a mar­quee syn­di­cate, $94M+ for 'in-be­tween' top­i­cal drug

For the past three years Frazier Healthcare Partners’ Bhaskar Chaudhuri has been carefully and quietly grooming Arcutis Therapeutics, a new dermatology play he co-founded to deliver topical formulations of well-known drugs. Now that the biotech is poised to enter Phase III, he’s being joined by a marquee syndicate for its $94.5 million Series C.

HBM Healthcare Investments, Vivo Capital, BlackRock, Omega Funds, Pivotal BioVentures, and Goldman Sachs jumped on board, joining Bain Capital Life Sciences, OrbiMed and RA Capital Management in backing Arcutis’ lead topical cream for plaque psoriasis.

A new com­pa­ny en­ters the Tec­fidera fight, of­fer­ing to kill two birds

The remedy for the most common side effect for one of the most common multiple sclerosis drugs is simple: aspirin.

Taking aspirin with Biogen’s Tecfidera will reduce the flush, a sometimes painful form of red skin irritation, many patients experiences. The problem is that the aspirin has to be taken at least 30 minutes before Tecfidera, turning a simple twice-a-day, one-dose oral drug into a staggered two-drug regimen.

UP­DAT­ED: Bris­tol-My­ers makes Op­di­vo pitch for front­line lung can­cer with open la­bel PhI­II study

Despite a head start, when Bristol-Myers Squibb and its pioneering checkpoint inhibitor Opdivo suffered a key lung cancer setback in 2016, they found themselves relegated to the backseat as Merck’s Keytruda seized the wheel on the road to immunotherapy stardom. Bristol-Myers has since suffered blow after blow in its quest to take a big slice of the lucrative market, peppered with some small successes. On Tuesday, the New Jersey drugmaker touted positive data from a Phase III open-label study in a bid to carve itself a piece of the frontline lung cancer market.

Take­da tees up $420M deal for celi­ac an­ti­dote, con­tin­u­ing R&D re­fo­cus

Sometime in the 1st century AD, a patient presented to Arataeus looking like a varicose ghost. He was “emaciated and atrophied, pale, feeble and incapable of performing any of his accustomed works,” the Greek physician wrote, with hollow temples and huge veins running all over his body.

A dysfunctional digestive system, Arataeus concluded – an imbalance he attributed to a “heat” deficiency in a system he and other Greeks regarded as functioning similarly to an oven – and coined a term: coeliac disease, after the Greek word for abdomen.

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:
