Ex ni­hi­lo: Take­da leads $100M+ round to fund biotech's sneak at­tack on tu­mors, pro­pelling new IL-2, CT­LA-4 drugs to clin­ic

Since emerg­ing out of stealth in 2018 with $30 mil­lion in launch mon­ey from At­las and F-Prime, Akre­via has kept a rel­a­tive­ly low pro­file, ham­mer­ing away at its plat­form tech­nol­o­gy to de­sign im­munother­a­pies with all their po­ten­cy but lit­tle of their side ef­fects. With an of­fi­cial CEO in place for al­most a year — and now a new name — the biotech is ready to step up with an­oth­er $100.5 mil­lion to bring its two lead com­pounds in­to the clin­ic.

Meet Xilio, a 35-strong team work­ing out of Waltham, MA. Where­as the orig­i­nal name had been de­rived from the Greek word for pre­ci­sion, Xilio draws in­spi­ra­tion from ex ni­hi­lo, a Latin term for cre­ation or big bang.

“We view how our mol­e­cules work as com­plete­ly off or dark when they’re cir­cu­lat­ing in the pe­riph­ery,” CEO Rene Rus­so told End­points News, “and this cre­ation or big bang as ef­fi­ca­cy in the tu­mor specif­i­cal­ly.”

Xilio’s pro­tein en­gi­neer­ing ap­proach­es shield the bind­ing ac­tiv­i­ty of mol­e­cules while they are trav­el­ling around the body, ex­plained Tim Clack­son, pres­i­dent and head of R&D. Once they meet the pro­teas­es in the tu­mor, the block­ing mod­ules are re­moved, re­leas­ing the ther­a­py just where it’s need­ed.

Un­der Clack­son, who ran the R&D shop at Ari­ad be­fore Take­da ac­quired it, the team went straight for IL-2 and CT­LA-4, two well-known tar­gets each with ap­proved ther­a­pies. Con­sid­er­ing the sig­nif­i­cant tox­i­c­i­ties as­so­ci­at­ed with the first-gen­er­a­tion treat­ments — Pro­leukin and Yer­voy both have black box warn­ings on their la­bels — many pa­tients can’t tol­er­ate the full dose. Xilio promis­es to change that with their re­com­bi­nant IL-2 and CT­LA-4 in­hibitor.

They are not the on­ly ones latch­ing on to IL-2, but Clack­son main­tains that theirs is a fun­da­men­tal­ly dif­fer­ent ap­proach to those tak­en by ri­vals such as Syn­thorx (now Sanofi), Ne­oleukin and Alk­er­mes — which have gen­er­al­ly fo­cused on bind­ing to spe­cif­ic re­cep­tors. The trou­bles Nek­tar has run in­to with its once-high-fly­ing NK­TR-214 af­ter Bris­tol-My­ers Squibb paid $1.85 bil­lion up­front to part­ner on it un­der­score the dif­fi­cul­ty of bal­anc­ing ef­fi­ca­cy and safe­ty.

Be­yond IL-2, Clack­son sees “clear un­tapped po­ten­tial” for cy­tokines as a class. Xilio has two pro­grams for tu­mor-se­lec­tive IL-12 and tu­mor-se­lec­tive IL-15 in the lead op­ti­miza­tion phase.

The Se­ries B, led by Take­da Ven­tures and fea­tur­ing SV Health In­vestors, MRL Ven­tures Fund (a ven­ture arm of Mer­ck), River­Vest Ven­ture Part­ners, Bay City Cap­i­tal, So­las­ta Ven­tures, M Ven­tures and Ipsen Ven­tures as well as the two orig­i­nal back­ers, gives them the fire­pow­er to steer the lead pro­grams to INDs by next year while mov­ing the oth­ers for­ward.

Jayson Pun­wani, part­ner at Take­da Ven­tures, is join­ing the board along­side Mike Ross of SV Health In­vestors, Pe­ter Dudek of MRL Ven­tures Fund and Nan­cy Hong of River­Vest Ven­ture Part­ners.

Ven­ture Cap­i­tal as a Strate­gic Part­ner: Fu­el­ing In­no­va­tion be­yond Fi­nance

The average level of investment required for a biotech start-up to succeed is increasing every year, elevating the pressure even further on venture capital to make smart financial investments. Financial investment alone, however, does not always guarantee that exciting innovations can be transformed into real businesses that make a meaningful difference to patients.

Beyond just capital

At Astellas Venture Management (AVM) – a wholly-owned venture capital organization within Astellas, headquartered in the San Francisco Bay Area – capital is just one of the ingredients we offer to add value to our biotechnology investments and partnerships. We generally take a strategic investor approach for companies in our invested portfolio, providing access to expertise, technology and/or resources in addition to the injection of finance. An equity investment from AVM can include access to Astellas’ research and development (R&D) capabilities and expertise, and a global network of partner academic institutions and biotechnology companies, to help advance and accelerate the start-up’s innovation.

UP­DAT­ED: Ver­tex joins Mer­ck, Pfiz­er — re­vamp­ing multi­bil­lion-dol­lar tri­al strat­e­gy as biotech R&D crum­bles

You can add Pfizer, Merck and — as we found out Friday morning — Vertex to the growing list of pharma giants hitting the pause button on a range of clinical trials. But not everyone in R&D is getting a red light.

Vertex says that it’s doing its best to keep working its pipeline strategy, coming up with a plan “to enable virtual clinic visits and home delivery of study drug to ensure study continuity and medical monitoring, and to facilitate study procedures.”

Covid-19 roundup: In­ter­cept, blue­bird and a grow­ing list of biotechs feel the pain as pan­dem­ic man­gles FDA, R&D sched­ules

Around 100 staffers at Boston area hospitals have now tested positive for Covid-19, spotlighting the growing risk that the pandemic will sideline many of the most essential workers in healthcare as caseloads peak in the US and around the globe. With more than 3,400 deaths, Spain has become the latest country to surpass the official death count attributed to the new coronavirus in China, where the outbreak originated. As of Thursday morning, confirmed global cases had crossed 470,000 and the death count eclipsed 21,000.

Af­ter crit­ics lam­bast­ed Gilead for grab­bing the FDA's spe­cial rare drug sta­tus on remde­sivir, they're giv­ing it back

Two days after Gilead won orphan drug status for remdesivir as a potential treatment for Covid-19, they’re handing it back.

The company was slammed from several sides after Gilead reported that the FDA had come through with the special status, which comes with 7 years of market exclusivity, the waiver of FDA fees and some tax credits as well. Typically, everyone who can get orphan status lands it without much of a fuss, but Democratic presidential candidate Bernie Sanders, Public Citizen and other consumer groups were outraged.

Mod­er­na CEO Stéphane Ban­cel out­lines a short path for emer­gency use of a coro­n­avirus vac­cine

NIAID director Anthony Fauci has left no doubts that it takes 12 to 18 months to get a new vaccine tested and in commercial use, in the best of circumstances. But in times of a global emergency — like these — maybe there’s another, faster route to follow.

In an SEC filing on Tuesday, Moderna $MRNA staked out a record-setting pathway to getting their mRNA vaccine into the frontline of the healthcare response as early as this fall. The SEC filing notes that CEO Stéphane Bancel told Goldman Sachs that an emergency use approval could allow the vaccine to go to healthcare workers and certain individuals in a matter of months — presumably provided the NIH sees the safety and efficacy data they would need from the Phase I.

Caught in a Covid-19 mael­strom, Eli Lil­ly locks down clin­i­cal tri­als as multi­bil­lion-dol­lar R&D ops de­rail

The Covid-19 pandemic has derailed Eli Lilly’s $6 billion R&D operations.

The pharma giant reported Monday morning that it has decided to hit the brakes on most new study starts and pause enrollment for most ongoing studies. Lilly adds that it is continuing dosing for ongoing studies, “but with study-by-study consideration.”

The pandemic has severely disrupted healthcare systems around the globe, says Lilly, making it difficult or impossible to conduct studies at many research sites. And there’s no timeline for when it expects to get back on track.

As share buy­backs come un­der scruti­ny, what's in store for the bio­phar­ma in­dus­try?

Stock buybacks are not to be permitted for companies that will be bailed out in the coronavirus stimulus package, Congressional leaders have signaled. To what degree the biopharma industry has relied on buybacks for earnings growth in recent years, and if the trend continues, are the big questions as scrutiny into the practice heightens and balance sheets weaken with the coronavirus pandemic wreaking havoc on global economies.

A Sin­ga­pore VC rais­es $200M for a new round, but will Covid-19 pre­vent it from rais­ing the rest?

A top Singaporean biotech venture fund is nearly halfway toward its largest ever fund, but in a sign of what could be in store for VCs amid a global economic freeze, said they could face headwinds raising the other half.

Vickers Venture Partners has secured $200 million out of a targeted $500 million for its 6th fund, first announced in early 2018. They’ve given themselves 13 months to complete the financing, Vickers founder Finian Tan told Deal Street Asia, but the financial frost settling amid the Covid-19 pandemic could slow efforts.

Strug­gling Unum ex­ecs are ready to con­sid­er a sale, merg­er or any deal that comes its way

Unum $UMRX is working its way through a survival plan of sorts.

After getting hit with a trio of FDA holds in its brief public history and triggering its second pivot to a new lead drug program while laying off 60% of the staff, the troubled penny stock biotech Unum Therapeutics has hatched new plans to secure financial backing while lining up a go-forward strategy for the company.

First, Lincoln Park Capital Fund has agreed to buy up to $25 million of the long-suffering stock, as Unum directs. And the executive team — led by CEO Chuck Wilson — has put everything on the table for consideration: a sale, acquisition, merger, licensing deal, you name it. The ACTR707 program, meanwhile, is being formally wrapped up — their second failed lead program.
