Icosavax nabs $51M as syn­thet­ic virus heads to­ward clin­ic

A new biotech is us­ing an ar­ti­fi­cial virus-like par­ti­cle to try to vac­ci­nate against the res­pi­ra­to­ry syn­cy­tial virus (RSV), a flu-like dis­ease for which no vac­ci­na­tion or cure ex­ists.

Icosavax launch­es with a $51 mil­lion Se­ries A fi­nanc­ing from Qim­ing Ven­ture Part­ners USA, Adams Street Part­ners, Sanofi Ven­tures and Nan­oDi­men­sion that will pro­pel it in­to a Phase I tri­al for IVX-121, their new vac­cine for old­er adults.

“The mag­ic of the VLP is that it looks and smells like a virus but it’s safe,” CEO Adam Simp­son told End­points News. “You get all the ben­e­fits of your body giv­ing off the dan­ger sig­nal with­out the down­side.”

RSV will af­fect vir­tu­al­ly all chil­dren be­low the age of 2, ac­cord­ing to the NIH, in­duc­ing a mild cold for most but forc­ing a small per­cent­age to be hos­pi­tal­ized. It can have se­vere con­se­quences in old­er adults, an­nu­al­ly con­tribut­ing to the deaths of 14,000 Amer­i­cans.

Simp­son wants you to pic­ture a soc­cer ball. He wants you to pic­ture it be­cause it’s rough­ly what a virus looks like if you add lit­tle anti­gen prongs to every black tile, and thus its rough­ly what their virus-like par­ti­cle (VLP) looks like.

This par­ti­cle works like a stan­dard virus-based vac­cine, trig­ger­ing the body’s im­mune re­sponse by bind­ing to lym­pho­cyte cells and mak­ing them think the body is in­fect­ed. Simp­son ar­gues this is safer than a con­ven­tion­al vac­cine be­cause it doesn’t in­volve any ac­tu­al for­eign virus.

This VLP, though, is crit­i­cal for RSV for oth­er rea­sons, he said. A vac­cine for the very com­mon virus has elud­ed re­searchers for years in large part be­cause the virus changes form dra­mat­i­cal­ly when it comes in­to con­tact with a cell. The trick, then, was to de­vise a vac­cine that would prime the body’s im­mune sys­tem against the virus’s pre-con­tact form.

The NIH cre­at­ed an anti­gen for that form last year, Simp­son said — pro­vid­ing a prong for Icosavax to at­tach to their VLP.

“What we’ve been able to do is come up with a tech­nique to make this soc­cer-ball-look­ing struc­ture with com­plex anti­gens and ac­tu­al­ly man­u­fac­ture it,” Simp­son said, “And that’s what’s nev­er been done be­fore.”

VLPs are al­ready wide­ly used for vac­cines, in­clud­ing for in­oc­u­la­tion against he­pati­tis B and hu­man pa­pil­lo­mavirus. But Simp­son and the builders of the VLP at the In­sti­tute for Pro­tein De­sign at the Uni­ver­si­ty of Wash­ing­ton told End­points this presents a ma­jor step for­ward by al­low­ing re­searchers to build them from scratch, us­ing com­pu­ta­tion­al mod­els — tech­niques, they said, that could be used in build­ing vac­cines for oth­er virus­es that have thus far elud­ed re­searchers.

The new mod­el works by mim­ic­k­ing the repet­i­tive struc­ture the body au­to­mat­i­cal­ly as­so­ciates with virus­es, Neil King told End­points.

“The beau­ti­ful thing about the par­ti­cle we’ve de­signed is they’re very ro­bust and ver­sa­tile,” King, an as­sis­tant pro­fes­sor at the In­sti­tute for Pro­tein De­sign said. “You could use the par­ti­cles to make HIV vac­cines or malar­ia vac­cines or flu vac­cines as well as RSV just by swap­ping out dif­fer­ent anti­gens.”

Icosavax will soon be­gin a Phase Ib tri­al on old­er adults, eval­u­at­ing safe­ty and proof-of-con­cept. Simp­son said they will soon look at oth­er in­di­ca­tions but de­clined to name them.

BiTE® Plat­form and the Evo­lu­tion To­ward Off-The-Shelf Im­muno-On­col­o­gy Ap­proach­es

Despite rapid advances in the field of immuno-oncology that have transformed the cancer treatment landscape, many cancer patients are still left behind.1,2 Not every person has access to innovative therapies designed specifically to treat his or her disease. Many currently available immuno-oncology-based approaches and chemotherapies have brought long-term benefits to some patients — but many patients still need other therapeutic options.3

The big mon­ey: Poised to make drug R&D his­to­ry, a Chi­na biotech un­veils uni­corn rac­ing am­bi­tions in a bid to raise $350M-plus on Nas­daq

Almost exactly three years after Shanghai-based Legend came out of nowhere to steal the show at ASCO with jaw-dropping data on their BCMA-targeted CAR-T for multiple myeloma, the little player with Big Pharma connections is taking a giant step toward making it big on Wall Street. And this time they want to seal the deal on a global rep after staking out a unicorn valuation in what’s turned out to be a bull market for biotech IPOs — in the middle of a pandemic.

Covid-19 roundup: Mod­er­na dos­es first pa­tients in PhII vac­cine tri­al; Eli Lil­ly touts clin­i­cal en­try of Ab­Cellera-dis­cov­ered an­ti­body

With an eye on kick-starting Phase III for its mRNA vaccine in July, Moderna said it’s dosed the first participants of each age cohort enrolled in the Phase II study.

Moderna is responsible for the whole trial, which is designed to recruit 600 healthy volunteers — 300 between the ages of 18 and 55, and another 300 older than 55. Two doses (50 μg and 100 μg) will be tested alongside placebo, and each participant receives two shots.

Roche nabs front­line OK for Avastin/Tecen­triq in com­mon liv­er can­cer, best­ing an old Bay­er drug

For the first time in 12 years, the FDA has approved a new frontline treatment for the most common form of liver cancer.

The agency okayed a combination of Roche’s anti-VEGF antibody Avastin and their immunotherapy Tecentriq for patients with unresectable or metastatic hepatocellular carcinoma (HCC). The approval comes two weeks after Roche and their big biotech sub Genentech published Phase III results showing the combo improved both progression-free survival and, crucially, helped patients live longer than the long-running standard-of-care, Bayer’s Nexavar.

Bio­Marin holds the line on bleeds with 4-year val­rox up­date on he­mo­phil­ia A — but what's this about an­oth­er de­cline in Fac­tor 8 lev­els?

BioMarin has posted some top-line results for their 4-year followup on the most advanced gene therapy for hemophilia A — extending its streak on keeping a handful of patients free of bleeds and off Factor VIII therapy, but likely stirring fresh worries over a continued drop in Factor VIII levels.

We just don’t know how big a drop.

We’ll see more data when the results are presented at the World Federation of Hemophilia in a couple of weeks. But in a statement out Sunday night, BioMarin $BMRN reported that none of the patients required Factor VIII treatment, adding:

As­traZeneca trum­pets the 'mo­men­tous' da­ta they found for Tagris­so in an ad­ju­vant set­ting for NSCLC — but many of the ex­perts aren’t cheer­ing along

AstraZeneca is rolling out the big guns this evening to provide a salute to their ADAURA data on Tagrisso at ASCO.

Cancer R&D chief José Baselga calls the disease-free survival data for their drug in an adjuvant setting of early stage, epidermal growth factor receptor-mutated NSCLC patients following surgery “momentous.” Roy Herbst, the principal investigator out of Yale, calls it “transformative.”

Ver­sant-backed, Bris­tol My­ers-stamped Re­pare Ther­a­peu­tics guns for $100M IPO

With a Bristol Myers Squibb endorsement in tow, Versant-backed cancer drug developer Repare Therapeutics has set its sights on a Nasdaq debut.

On Friday, the Montreal-based company with operations in Cambridge, Massachusetts that is yet to enter the clinic, unveiled plans for a $100 million IPO, banking on its “synthetic lethality” platform.

The basic idea is to target the genetic basis of tumors, a common idea across precision oncology medicines. But instead of targeting the perpetrator mutation directly, the compound is designed to go after the other gene in the gene pair. The rationale is based on the decades-old genetic principle that indicates two mutations are lethal only when combined together.

My­ovant’s re­l­u­golix wins a piv­otal prostate can­cer show­down with an old stan­dard — com­ing down to the wire on ap­provals

Myovant $MYOV has rounded the final turn in its development race to get relugolix down to the regulatory wire at the FDA. And the biotech joined the virtual crowd at ASCO with the kind of data needed to keep the investor crowd’s attention.

Much of the attention on the drug has been focused on uterine fibroids, where AbbVie just scored a regulatory win for their rival drug Oriahnn (elagolix) as the biotech posted results in prostate cancer at the ASCO meeting.

In a sting­ing set­back, Pfiz­er’s can­cer block­buster Ibrance flops in key ad­ju­vant set­ting

One of Pfizer’s top, long-running R&D catalysts has gone up in smoke, and it took an $11 billion bite of their market cap in the process.

The monitoring committee determined that Pfizer’s adjuvant study using Ibrance combined with standard endocrine therapy in an adjuvant setting for early-stage breast cancer has officially failed to make the cut. The combo failed to beat the standard alone, tripping over the futility analysis. And the Pfizer team will now wrap the study early after pumping up hopes that their blockbuster cancer therapy could find billions more by proving its efficacy for disease-free survival in a major area — something AstraZeneca just accomplished with Tagrisso to great fanfare.
