Clene Nanomed­i­cine, re­search­ing the use of gold atoms to slow ALS pro­gres­sion, nets $42.5M Se­ries D

A bio­phar­ma that us­es gold to de­vel­op treat­ments for neu­rode­gen­er­a­tive dis­eases just got a lit­tle bit rich­er.

Rob Ether­ing­ton

Clene Nanomed­i­cine pulled in $42.5 mil­lion in a Se­ries D fi­nanc­ing round Wednes­day, mon­ey which will go to­ward ad­vanc­ing its lead pro­gram through a Phase III plat­form tri­al in ALS and sup­port Phase II tri­als in MS, Parkin­son’s dis­ease and ALS. CEO Rob Ether­ing­ton said that by the end of 2021, Clene will know whether or not the can­di­date, called CNM-Au8, will prove ef­fec­tive.

“It will take us to the end of all these clin­i­cal end­points,” Ether­ing­ton told End­points News. “The ex­cit­ing thing for us is that one as­set could po­ten­tial­ly be in­di­cat­ed to im­prove neu­ro­log­i­cal func­tion in MS, as well as ALS, and [though] Parkin­son’s is the slow­er pro­gram, this mon­ey is go­ing to help us launch more com­plete­ly that pro­gram.”

CNM-Au8 is a liq­uid sus­pen­sion of gold nanocrys­tals that cat­alyze in­tra­cel­lu­lar bi­o­log­i­cal re­ac­tions. Such cat­alyza­tion can lead to im­prove­ment in nerve cell sur­vival, func­tion, and com­mu­ni­ca­tion. Chem­i­cal­ly, the “clean sur­faces” of the nanocrys­tals help nor­mal­ize ATP pro­duc­tion in cells, which is lack­ing in se­ri­ous neu­ro­log­i­cal dis­eases like ALS, CMO Robert Glanz­man said.

“We’re pro­vid­ing bioen­er­gy sup­port to cells,” Glanz­man said. “There’s a rea­son why we tend to get neu­rode­gen­er­a­tive dis­eases as we get old­er, and that is be­cause as we age, there’s a lin­ear loss of bioen­er­getic ca­pac­i­ty with­in neu­rons … and what we’re do­ing is ac­tu­al­ly pro­vid­ing these neu­rons and oth­er cells with free en­er­gy, es­sen­tial­ly.”

In terms of vis­i­ble symp­toms, Glanz­man added that pa­tients tak­ing CNM-Au8 will see bet­ter strength, mus­cle mass and be able to speak, breathe and swal­low more eas­i­ly over a longer pe­ri­od of time.

Clene’s Phase III study comes as it was se­lect­ed to par­tic­i­pate in the first-ever plat­form tri­al for ALS, which en­rolled its first pa­tients ear­li­er this month. The tri­al com­pares three sep­a­rate treat­ments for the dis­ease, with UCB’s zilu­coplan and Bio­haven’s verdiper­stat join­ing CNM-Au8 at Har­vard-backed Mass­a­chu­setts Gen­er­al Hos­pi­tal in test­ing 480 to­tal pa­tients.

Though de­layed from a March start due to the Covid-19 pan­dem­ic, the plat­form tri­al aims to ex­pe­dite the de­vel­op­ment of ther­a­pies for a dis­ease that ad­vances rapid­ly and that has few ef­fec­tive treat­ment op­tions. On­ly rilu­zole, al­so known as Ri­lutek and OK’ed in 1995, shows any mea­sur­able ef­fect on ALS pa­tients, Ether­ing­ton said.

“Rilu­zole, which func­tion­al­ly is re­al­ly the on­ly drug that most peo­ple with ALS use, was orig­i­nal­ly ap­proved to de­lay the need for tra­cheostomies to en­cour­age breath­ing for an ex­tra cou­ple months,” Ether­ing­ton said. “But it has a very mod­est ef­fect gen­er­al­ly. It is the stan­dard of care, how­ev­er, be­cause it’s the on­ly re­al­ly marked­ly rel­e­vant drug that’s been ap­proved for ALS in this coun­try. There’s a few oth­ers but most of them do very lit­tle.”

Clene has two oth­er pro­grams in the pipeline, though nei­ther have reached the clin­ic just yet. The first is a top­i­cal gel con­tain­ing sil­ver and zinc ions, with re­searchers look­ing at burn treat­ment, ac­cel­er­at­ed wound-heal­ing and as an an­ti-in­fec­tive. There’s al­so a gold-plat­inum ther­a­peu­tic be­ing stud­ied for use in on­col­o­gy, which is still in the ini­tial in vit­ro stage.

The bot­tom line for Clene though is that find­ing a treat­ment op­tion for the ex­treme­ly dif­fi­cult ALS in­di­ca­tion be­comes clos­er to re­al­i­ty, with a po­ten­tial­ly huge im­pact on the field.

“The way you and I move and can grasp things and can talk, all this fine mo­tor move­ment we take for grant­ed,” Ether­ing­ton said. “An ALS pa­tient los­es these and this is ex­act­ly what we are study­ing.”

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

The top career staff at the FDA have vowed not to let politics get in the way of 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 health agencies under his purview — including the FDA — of their rulemaking 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.

#ES­MO20: Eli Lil­ly shows off the da­ta for its Verzenio suc­cess. Was it worth $18 bil­lion?

The press release alone, devoid of any number except for the size of the trial, added nearly $20 billion to Eli Lilly’s market cap back in June. Now investors and oncologists will get to see if the data live up to the hype.

On Sunday at ESMO, Eli Lilly announced the full results for its Phase III MonarchE trial of Verzenio, showing that across over 5,000 women who had had HR+, HER2- breast cancer, the drug reduced the odds of recurrence by 25%. That meant 7.8% of the patients on the drug arm saw their cancers return within 2 years, compared with 11.3% on the placebo arm.

#ES­MO20: Am­gen team nails down sol­id ear­ly ev­i­dence of AMG 510’s po­ten­tial for NSCLC, un­lock­ing the door to a wave of KRAS pro­grams

The first time I sat down with Amgen’s Greg Friberg to talk about the pharma giant’s KRAS G12C program for sotorasib (AMG 510) at ASCO a little more than a year ago, there was high excitement about the first glimpse of efficacy from their Phase I study, with 5 of 10 evaluable non-small cell lung cancer patients demonstrating a response to the drug.

After decades of failure targeting KRAS, sotorasib offered the first positive look at a new approach that promised to open a door to a whole new approach by targeting a particular mutation to a big target that had remained “undruggable” for decades.

#ES­MO20: Out to beat Tagris­so, J&J touts 100% ORR for EGFR bis­pe­cif­ic/TKI com­bo — fu­el­ing a quick leap to PhI­II

J&J’s one-two punch on EGFR-mutant non-small cell lung cancer has turned up some promising — although decidedly early — results, fueling the idea that there’s yet room to one up on third-generation tyrosine kinase inhibitors.

Twenty out of 20 advanced NSCLC patients had a response after taking a combination of an in-house TKI dubbed lazertinib and amivantamab, a bispecific antibody targeting both EGFR and cMET engineered on partner Genmab’s platform, J&J reported at ESMO. All were treatment-naïve, and none has seen their cancer progress at a median follow-up of seven months.

#ES­MO20: As­traZeneca aims to spur PRO­found shift in prostate can­cer treat­ment with Lyn­parza OS da­ta

AstraZeneca has unveiled the final, mature overall survival data that cemented Lynparza’s first approval in prostate cancer approval — touting its lead against rivals with the only PARP inhibitor to have demonstrated such benefit.

But getting the Merck-partnered drug to the right patients remains a challenge, something the companies are hoping to change with the new data cut.

The OS numbers on the subgroup with BRCA1/2 or ATM-mutated metastatic castration-resistant prostate cancer are similar to the first look on offer when the FDA expanded the label in May: Lynparza reduced the risk of death by 31% versus Xtandi and Zytiga. Patients on Lynparza lived a median of 19.1 months, compared to 14.7 months for the anti-androgen therapies (p = 0.0175).

#ES­MO20: Look out Mer­ck. Bris­tol My­ers and Ex­elix­is stake out their com­bo’s claim to best-in-class sta­tus for front­line kid­ney can­cer

Now that the PD-(L)1 checkpoints are deeply entrenched in the oncology market, it’s time to welcome a wave of combination therapies — beyond chemo — looking to extend their benefit to larger numbers of patients. Bristol Myers Squibb ($BMY} and Exelixis {EXEL} are close to the front of that line.

Today at ESMO the collaborators pulled the curtain back on some stellar data for their combination of Opdivo (the PD-1) and Cabometyx (the TKI), marking a significant advance for the blockbuster Bristol Myers franchise while offering a big leg up for the team at Exelixis.

An­a­lysts are quick to pan Eli Lil­ly's puz­zling first cut of pos­i­tive clin­i­cal da­ta for its Covid-19 an­ti­body

Eli Lilly spotlighted a success for one of 3 doses of their closely-watched Covid-19 antibody drug Wednesday morning. But analysts quickly highlighted some obvious anomalies that could come back to haunt the pharma giant as it looks for an emergency use authorization to launch marketing efforts.

The pharma giant reported that LY-CoV555, developed in collaboration with AbCellera, significantly reduced the rate of hospitalization among patients who were treated with the antibody. The drug arm of the study had a 1.7% hospitalization rate, compared to 6% in the control group, marking a 72% drop in risk.

#ES­MO20: It’s not just Keytru­da any­more — Mer­ck spot­lights 3 top ear­ly-stage can­cer drugs

Any $12 billion megablockbuster in the portfolio tends to overshadow everything else in the pipeline. Which is something Merck can tell you a little bit about.

Keytruda not only dominates the PD-(L)1 field, it looms over everything Merck does, to the point some analysts wonder if Merck is a one-trick pony.

There’s no shortage of Keytruda data on display at ESMO this weekend, but now the focus is shifting to the future role of new drugs and combos in maintaining that lead position for years to come. And the pharma giant has a special focus for 3 early-stage efforts where Roger Perlmutter’s oncology team is placing some big bets.

#ES­MO20: Trodelvy da­ta show that Gilead­'s $21B buy­out may have been worth the big pre­mi­um

Gilead CEO Dan O’Day has been on a shopping spree. And while some analysts gawked at the biotech’s recent $21 billion Immunomedics buyout, new data released at virtual ESMO 2020 suggest the acquisition may have been worth the hefty price.

The deal, announced last weekend, will give California-based Gilead $GILD Trodelvy, which was recently approved for metastatic triple-negative breast cancer (mTNBC).
