Aer­pio shares tum­ble as lead eye drug trips up in mid-stage di­a­bet­ic retinopa­thy study

Rough­ly two years af­ter rais­ing $40 mil­lion in a pri­vate place­ment, Aer­pio Phar­ma­ceu­ti­cals’ lead ex­per­i­men­tal eye drug has hit a road­block af­ter fail­ing a mid-stage study in pa­tients with non-pro­lif­er­a­tive di­a­bet­ic retinopa­thy (NPDR) — the ear­li­est stage of di­a­bet­ic eye dis­ease, which oc­curs when high blood sug­ar lev­els cause dam­age to blood ves­sels in the reti­na.

These blood ves­sels can swell and leak, or close re­strict­ing blood flow and even­tu­al­ly cul­mi­nate in blind­ness. In the 167-pa­tient tri­al, called TIME-2b, pa­tients were giv­en the drug — AKB-9778 —  (once or twice dai­ly) or place­bo (once or twice dai­ly) for 48 weeks. The main goal was to im­prove the the study eye di­a­bet­ic retinopa­thy sever­i­ty score (DRSS) by two or more steps com­pared to the place­bo.

Ad­min­is­tra­tion of AKB-9778 twice dai­ly missed the study’s pri­ma­ry end­point, the com­pa­ny said on Mon­day. Shares of the Cincin­nati-based drug de­vel­op­er $AR­PO cratered more than 68% to $1.36 in pre-mar­ket trad­ing.

About 9.6% of pa­tients giv­en AKB-9779 twice dai­ly ex­pe­ri­enced such an im­prove­ment, ver­sus 3.8% on the place­bo — draw­ing a less than rosy p val­ue (p=0.270). The rates of pro­gres­sion to sight-threat­en­ing com­pli­ca­tions, in­clud­ing di­a­bet­ic mac­u­lar ede­ma (DME) and/or pro­lif­er­a­tive di­a­bet­ic retinopa­thy (PDR), dur­ing the treat­ment pe­ri­od were sim­i­lar be­tween treat­ment groups, Aer­pio not­ed, adding that the use of the ex­per­i­men­tal drug had an “en­cour­ag­ing” im­pact on key sec­ondary goals, in­clud­ing a mea­sure of kid­ney func­tion and in­traoc­u­lar pres­sure.

Un­like pa­tients with di­a­bet­ic eye dis­ease who are typ­i­cal­ly giv­en an­ti-VEGF in­jec­tions in­to the eye, AKB-9778 is self-ad­min­is­tered sub­cu­ta­neous­ly by the pa­tient, akin to in­sulin. The ex­per­i­men­tal drug is a small mol­e­cule in­hibitor of VE-PTP, the most crit­i­cal neg­a­tive reg­u­la­tor of Tie2 — a path­way be­lieved to sta­bi­lize vas­cu­la­ture — in dis­eased blood ves­sels. In a sep­a­rate study, called TIME-2, AKB-9778 im­proved un­der­ly­ing symp­toms by two or more steps on a di­a­bet­ic retinopa­thy sever­i­ty scale in both eyes.

Un­de­terred by the TIME-2b fail­ure, Aer­pio chief Stephen Hoff­man ex­pressed en­thu­si­asm for the to­tal­i­ty of da­ta on the drug. “(C)ol­lec­tive­ly these da­ta sup­port a po­ten­tial­ly im­por­tant role of the Tie2 path­way for the treat­ment of di­a­bet­ic com­pli­ca­tions, as well as for open an­gle glau­co­ma,” he said in a state­ment, adding that a Phase Ib study of a top­i­cal drop for­mu­la­tion of AKB-9778 is ex­pect­ed to com­mence in the sec­ond quar­ter.

Aer­pio al­so has an­oth­er ex­per­i­men­tal eye drug in de­vel­op­ment, in ad­di­tion to an in­ves­ti­ga­tion­al ther­a­py for in­flam­ma­to­ry bow­el dis­ease.

Un­der fire, FDA to is­sue stricter guid­ance for Covid-19 vac­cine EUA this week — re­port

The FDA has been insisting for months that a Covid-19 vaccine had to be at least 50% effective – a measure of transparency meant to shore public trust in the agency and in a vaccine that had been brought forward at record speed and record political pressure. But now, with concerns of a Trump-driven authorization arriving before the election, the agency may be raising the bar.

The FDA is set to release new guidance that would raise safety and efficacy requirements for a vaccine EUA above earlier guidance and above the criteria used for convalescent plasma or hydroxychloroquine, The Washington Post reported. Experts say this significantly lowers the odds of an approval before the election on November 3, which Trump has promised despite vocal concerns from public health officials, and could help shore up public trust in the agency and any eventual vaccine.

Trump’s HHS claims ab­solute au­thor­i­ty over the FDA, clear­ing path to a vac­cine EUA

The top career staff at the FDA has vowed not to let politics overrule science when looking at vaccine data this fall. But Alex Azar, who happens to be their boss’s boss, apparently won’t even give them a chance to stand in the way.

In a new memorandum issued Tuesday last week, the HHS chief stripped the FDA and other health agencies under his purview of their rule making ability, asserting all such power “is reserved to the Secretary.” Sheila Kaplan of the New York Times first obtained and reported the details of the September 15 bulletin.

UP­DAT­ED: Still held down by clin­i­cal hold, No­var­tis' Zol­gens­ma falls fur­ther be­hind Bio­gen and Roche as FDA asks for a new piv­otal study

Last October, the FDA slowed down Novartis’ quest to extend its gene therapy to older spinal muscular atrophy patients by slapping a partial hold on intrathecal administration. Almost a year later, the hold is still there, and regulators are adding another hurdle required for regulatory submission: a new pivotal confirmatory study.

The new requirement — which departs significantly from Novartis’ prior expectations — will likely stretch the path to registration beyond 2021, when analysts were expecting a BLA submission. That could mean more time for Biogen to reap Spinraza revenues and Roche to ramp up sales of Evrysdi in the absence of a rival.

Scoop: ARCH’s Bob Nelsen is back­ing an mR­NA up­start that promis­es to up­end the en­tire man­u­fac­tur­ing side of the glob­al busi­ness

For the past 2 years, serial entrepreneur Igor Khandros relied on a small network of friends and close insiders to supply the first millions he needed to fund a secretive project to master a new approach to manufacturing mRNA therapies.

Right now, he says, he has a working “GMP-in-a-box” prototype for a new company he’s building — after launching 3 public companies — which plans to spread this contained, precise manufacturing tech around the world with a set of partners. He’s raised $60 million, recruited some prominent experts. And not coincidentally, he’s going semi-public with this just as a small group of pioneers appears to be on the threshold of ushering in the world’s first mRNA vaccines to fight a worldwide pandemic.

Isaac Veinbergs, Libra CEO

With $29M in Se­ries A, Boehringer-backed Li­bra looks to tack­le neu­rode­gen­er­a­tion through cel­lu­lar clean­ing

Can the natural process by which cells clean out toxic proteins be harnessed to create potential treatments for neurodegenerative disorders?

That’s the question Libra Therapeutics will be trying to answer, as the new biotech officially launched Wednesday morning with $29 million in Series A financing. The company has three preclinical programs at the ready, with its lead candidate targeting ALS and frontotemporal dementia. But CEO Isaac Veinbergs said he hopes to develop therapies for a wide range of diseases, including Parkinson’s, Alzheimer’s and Huntington’s.

As its biotechs hit the pan­dem­ic ex­it, Lon­gi­tude rais­es $585M for new neu­ro, can­cer, ag­ing and or­phan-fo­cused fund

The years have been kind to Longitude Capital. This year, too.

A 2006 spinout of Pequot Capital, its founders started their new firm just four years before the parent company would go under amid insider trading allegations. Their first life sciences fund raised $325 million amid the financial crisis, they added a second for $385 million and then in, 2016, a third for $525 million. In the last few months, the pandemic biotech IPO boom netted several high-value exits from those funds, as Checkmate, Vaxcyte, Inozyme and Poseida all went public.

Im­metas Ther­a­peu­tics nabs $11M Se­ries A to nar­row their bis­pe­cif­ic work tar­get­ing in­flam­ma­tion in age-re­lat­ed dis­eases

How does a biotech celebrate its two-year anniversary? For Immetas Therapeutics, it’s with an $11 million Series A round and a game plan to fight age-related disease.

Co-founders Gene Wang and David Sinclair came together years ago around the idea that inflammation is the ultimate process driving age-related illnesses, including cancer. The duo launched Immetas in 2018 and packed the staff with industry experts. Wang, who says he’s always had an entrepreneurial spirit, has held lead roles at Novartis, GSK, Bristol Myers Squibb and Merck. He’s worked on blockbuster drugs like Humira, Gardasil, Varubi and Zolinza. And now, he’s channeling that spirit as CEO.

Af­ter bruis­ing re­jec­tion, blue­bird and Bris­tol My­ers Squibb land ide-cel pri­or­i­ty re­view. But will it mat­ter for the CVR?

With the clock all but up, the FDA accepted and handed priority review to Bristol Myers Squibb and bluebird bio’s BCMA CAR-T, keeping a narrow window open for Celgene investors to still cash in on the $9 CVR from the $63 billion Celgene merger.

The acceptance comes five months after the two companies weres slammed with a surprise refuse-to-file that threatened to foreclose the CVR entirely. Today’s acceptance sets the FDA decision date for March 27, 2021 – or precisely 4 days before the CVR deadline of March 31. Given the breakthrough designation and strong pivotal data — 81.5% response rate, 35.2% complete response rate — priority review was largely expected.
