Vi­da Ven­tures co-leads Dyne's $115M megaround for next-gen oli­go ther­a­pies aimed square­ly at mus­cles

Dyne Ther­a­peu­tics start­ed out last April with a mod­est $50 mil­lion to mine tar­get­ed mus­cle dis­ease ther­a­pies from its in-house con­ju­gate tech­nol­o­gy. The biotech has now con­vinced more in­vestors that it’s got gems on its hands, clos­ing $115 mil­lion in fresh fi­nanc­ing to push its next-gen oligonu­cleotide drugs in­to the clin­ic.

Joshua Brumm

Vi­da Ven­tures and Sur­vey­or Cap­i­tal led the round, joined by a group of oth­er new back­ers in­clud­ing Welling­ton Man­age­ment Com­pa­ny, Lo­gos Cap­i­tal and Franklin Tem­ple­ton.

At­las — where Dyne was in­cu­bat­ed — al­so re­turned along­side For­bion and MPM.

Ste­fan Vi­torovic, who co-found­ed Vi­da with Arie Bellde­grun and oth­ers, took the lead on this one. Dyne’s FORCE plat­form match­es ex­act­ly their ap­petite for bold vi­sions in the fu­ture of med­i­cine, with the po­ten­tial to de­liv­er “life-chang­ing out­comes” for pa­tients with mus­cle dis­eases, he said.

This is how the biotech plans to do it: By link­ing an an­ti­body to an oligonu­cleotide, Dyne’s ther­a­pies are en­gi­neered to hone in on mus­cle cells and de­grade on­ly dis­ease-caus­ing RNA, there­by avoid­ing sys­temic tox­i­c­i­ty is­sues.

Ro­mesh Sub­ra­man­ian

Ro­mesh Sub­ra­man­ian, a co-founder of what is now Trans­late Bio, helped launch the op­er­a­tions as an en­tre­pre­neur-in-res­i­dence at At­las. He’s since hand­ed the CEO ba­ton to Joshua Brumm and moved to the CSO post.

“When you de­liv­er a naked oli­go, very lit­tle gets to the mus­cle,” he told C&EN back in 2019.

That means a lack of speci­fici­ty and po­ten­tial safe­ty prob­lems for drugs like Sarep­ta’s con­tro­ver­sial Ex­ondys 51. While Dyne is aim­ing di­rect­ly at that mar­ket with its Duchenne mus­cu­lar dy­s­tro­phy pro­gram, its ini­tial fo­cus is on my­oton­ic dy­s­tro­phy.

Trail­ing close­ly is a third ther­a­py for fa­cioscapu­lo­humer­al mus­cu­lar dy­s­tro­phy, fol­lowed by dis­cov­ery work in the car­diac and meta­bol­ic are­nas.

Su­san­na High

How would the ap­proach com­pare to gene ther­a­pies, which are crop­ping up at Sarep­ta and oth­er new­er play­ers fo­cused on mus­cle dis­eases? We didn’t get a chance to ask Dyne, which is shy­ing away from in­ter­views this morn­ing — per­haps a sign of up­com­ing plans in a boom­ing biotech IPO mar­ket.

Un­der Brumm, Dyne has been on a bit of a hir­ing spree re­cent­ly, poach­ing Su­san­na High from blue­bird to be COO, ap­point­ing ex-Cel­gene ex­ec Daniel Wil­son as VP of in­tel­lec­tu­al prop­er­ty, and scoop­ing De­bra Feld­man from Sage Ther­a­peu­tics as head of reg­u­la­to­ry.

Forge Bi­o­log­ics’ cGMP Com­pli­ant and Com­mer­cial­ly Vi­able Be­spoke Affin­i­ty Chro­matog­ra­phy Plat­form

Forge Biologics has developed a bespoke affinity chromatography platform approach that factors in unique vector combinations to streamline development timelines and assist our clients in efficiently entering the clinic. By leveraging our experience with natural and novel serotypes and transgene conformations, we are able to accelerate affinity chromatography development by nearly 3-fold. Many downstream purification models are serotype-dependent, demanding unique and time-consuming development strategies for each AAV gene therapy product1. With the increasing demand to propel AAV gene therapies to market, platform purification methods that support commercial-scale manufacturing of high-quality vectors with excellent safety and efficacy profiles are essential.

Cy­to­ki­net­ics’ ALS drug fails PhI­II, leav­ing the biotech with a sin­gle late-stage prospect

Cytokinetics’ candidate for the muscle disease amyotrophic lateral sclerosis, or ALS, failed a Phase III trial, the Bay Area biotech announced Friday morning.

At a second interim analysis of the trial, an independent review committee recommended that Cytokinetics discontinue its COURAGE-ALS trial for reldesemtiv, as it “found no evidence of effect” compared to placebo on the primary or key secondary endpoints.

CHMP gives thumbs-up for We­govy use in ado­les­cents, along with nine new drug rec­om­men­da­tions

The European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) recommended nine drugs for approval this week while also giving thumbs up for six expanded indications, including Novo Nordisk’s approved obesity medication Wegovy for younger people. Wegovy is already approved as an obesity treatment in the EU for adults, and the new indication would allow prescriptions for adolescents aged 12 and older.

Green­Light re­ceives buy­out of­fer; Apol­lomics com­pletes SPAC merg­er

RNA biotech GreenLight Biosciences has been handed an offer for potential acquisition.

GreenLight said in a release that it has received a non-binding “indication of interest” from Fall Line Endurance Fund to acquire GreenLight’s capital stock for $0.60 per share in cash. The release said any potential agreement between the two parties would depend on certain conditions.

Through a special committee, the biotech will evaluate the offer but added there’s no certainty a deal will go forward. GreenLight will also not make any more announcements until a deal comes through or “otherwise determines” a statement is necessary.

Mathai Mammen, FogPharma's next CEO

Math­ai Mam­men hands in J&J's R&D keys to lead Greg Ver­dine’s Fog­Phar­ma 

In the early 1990s, Mathai Mammen was a teaching assistant in Greg Verdine’s Science B46 course at Harvard. In June, the former R&D head at Johnson & Johnson will succeed Verdine as CEO, president and chair of FogPharma, the same month the seven-year-old biotech kickstarts its first clinical trial.

After leading R&D at one of the largest drugmakers in the world, taking the company through more than half a dozen drug approvals in the past few years, not to mention a Covid-19 vaccine race, Mammen departed J&J last month and will take the helm of a Cambridge, MA biotech attempting to go after what Verdine calls the “true emperor of all oncogenes” — beta-catenin.

Austin biotech Mol­e­c­u­lar Tem­plates lays off more than 100 staffers as pipeline nar­rows

Molecular Templates is ridding itself of a Phase I HER2 asset and fine-tuning its pipeline to focus on three programs and a preclinical Bristol Myers Squibb collaboration. With the narrowed scope on its so-called engineered toxin bodies, the Austin, TX biotech is laying off about half of its staff.

That’s a little more than 100 employees, per an SEC filing. Molecular’s layoffs, approved by its board Wednesday, add to the dozens of pullbacks in the industry in the first three months of 2023.

Sen­ate Fi­nance Com­mit­tee lobs more bi­par­ti­san pres­sure on­to PBMs

Congress is honing in on how it wants to overhaul the rules of the road for pharmacy benefit managers, with a Senate Finance Committee hearing Thursday serving as the latest example of the Hill’s readiness to make changes to how pharma middlemen operate.

While pledging to ensure patients and pharmacies “don’t get a raw deal,” Finance Committee Chair Ron Wyden (D-OR) laid out the beginning of what looks like a major bipartisan effort — moves the PBM industry is likely to challenge vigorously.
