Nim­bus founder Rosana Kapeller has a new com­pa­ny, with $50M and an eye on the ‘re­peatome’

Rosana Kapeller left Nim­bus two years ago de­ter­mined, af­ter 2 decades and 3 com­pa­nies, that her next spot would be as CEO. To­day, af­ter a 7-month sab­bat­i­cal and a stint at a top VC firm, the joc­u­lar com­pu­ta­tion­al bi­ol­o­gy pi­o­neer is back. And with full con­trol.

“I re­al­ly want­ed to… make a unique or­ga­ni­za­tion, a unique cul­ture,” Kapeller told End­points News. I want­ed that chal­lenge.”

And a chal­lenge it will be, both sci­en­tif­i­cal­ly and be­cause, well, there’s a pan­dem­ic keep­ing much of her 10-per­son team work­ing from her home. “This is a hard time to start a com­pa­ny,” she ac­knowl­edged.

Still, Kapeller is con­fi­dent, plac­ing her faith both in the am­bi­tious sci­ence of her new com­pa­ny and in her own ex­pe­ri­ence as a busi­ness­woman, dat­ing back to her up­bring­ing in a busi­ness-fo­cused fam­i­ly in Brazil. The new com­pa­ny is ROME Ther­a­peu­tics and it’s launch­ing out of stealth mode with $50 mil­lion in Se­ries A fund­ing from GV — where Kapeller served as en­tre­pre­neur-in-res­i­dence for the last year — ARCH Ven­tures, and Part­ners In­no­va­tion Fund. The biotech is one of a se­ries that have arisen in the past few years to tar­get parts of what was once deemed “junk DNA”: the 97-99% of ge­net­ic code that doesn’t code for pro­teins. Al­though sci­en­tists have known for decades now that at least parts of this vast nu­cle­ic flot­sam serve key func­tions, un­tan­gling those func­tions has been a ma­jor hur­dle. Drug­ging them has been an even larg­er one.

ROME will tar­get one seg­ment of this erst­while junk called the “re­peatome.” The name has yet to catch on — a PubMed search pro­duced 22 re­sults and the Wikipedia page is a sin­gle para­graph at­trib­uted to one PLOS pa­per out of France — but the field has slow­ly gained steam since a 2011 Sci­ence pa­per, on which ROME co-founder David Ting was lead au­thor.

The re­peatome refers to some 50% of hu­man DNA that is made up of se­quences that re­peat over and over again — like a mu­si­cal or lit­er­ary mo­tif — and that don’t make any pro­teins. Some of these, as sci­en­tists have long known, are retro­virus­es that in­fect­ed us and em­bed­ded their codes in our DNA over mil­lions of years of evo­lu­tions. Oth­er se­quences, though, are “virus-like,” said Ting. Most of the time these se­quences are blocked from do­ing any­thing, trapped by methyl agents or hi­s­tones that wrap like chains around DNA. But in some in­stances — such as some can­cers — dis­tressed cells take the chains off and trans­late the se­quences in­to RNA. Those RNA se­quences don’t make any pro­teins. But they look like RNA virus­es and ac­ti­vate the in­nate im­mune sys­tem as a virus would, call­ing it to at­tack a tu­mor.

“These re­peats are like the first re­spon­ders, telling the body these cells are be­com­ing un­con­trol­lable — con­trol it,” Kapeller said.

Two prob­lems can emerge. First, can­cer cells can de­vel­op ways of re­verse tran­scrib­ing these RNA se­quences back in­to their genome, both si­lenc­ing the im­mune sig­nals and adding to the can­cer’s ge­net­ic vari­abil­i­ty. In some au­toim­mune con­di­tions, the op­po­site prob­lem is at play, Kapeller said. Healthy cells send off these RNA re­peats, trig­ger­ing a dam­ag­ing im­mune re­sponse.

Kapeller talks about ROME’s role as restor­ing “yin and yang”: Keep­ing the im­mune sig­nals go­ing in can­cer and turn­ing them off in au­toim­mune dis­eases. ROME has not yet re­vealed how they plan on do­ing that, but when Ting first hy­poth­e­sized that can­cers were tran­scrib­ing these sig­nals, he start­ed a clin­i­cal tri­al with a com­mon HIV drug on 4th line colon can­cer pa­tients. The HIV drug, which is meant to stop the HIV virus from re­verse tran­scrib­ing it­self, ap­peared to in­hib­it the can­cer’s abil­i­ty to re­verse tran­scribe the RNA sig­nals. The pa­tients on the study main­tained their con­di­tion, a rar­i­ty for that form and stage of can­cer.

“Some­how can­cer has re­pur­posed this process to repli­cate and grow in­to tu­mor,” Ting told End­points, de­scrib­ing his dis­cov­ery. “It was kind of an ac­ci­dent, an ac­ci­dent of some­thing we were told was junk and find­ing the junk was ac­tu­al­ly do­ing some­thing.”

That some­thing evad­ed sci­en­tists in part be­cause ear­ly DNA se­quencers lacked the abil­i­ty to pick up and an­a­lyze these vast codex­es of DNA and study which re­peats were be­ing tran­scribed in­to RNA. To do so, ROME will re­ly on two new but es­tab­lished tech­niques, se­quenc­ing of long stretch­es of DNA and se­quenc­ing of the RNA be­ing tran­scribed in­side a cell, along­side a ma­chine learn­ing ap­proach set up by the­o­ret­i­cal physi­cist Ben­jamin Green­baum. In part, that’s what made it a fit­ting project for Kapeller, who did com­pu­ta­tion­al work at Mil­len­ni­um and Ailleron and then was en­list­ed by At­las Ven­tures to launch Nim­bus, one of the first ma­jor com­pu­ta­tion­al biotechs.

Al­though it will be Kapeller’s first stint as a CEO, it will hard­ly be her first time in lead­er­ship. Nim­bus lacked a CEO for its first 4.5 years, she notes, leav­ing con­trol of the biotech be­tween her­self and the board. She says that she’s learned a few things from her ex­pe­ri­ence with past com­pa­nies: That con­trol and com­mand doesn’t work, trans­paren­cy is nec­es­sary, and di­ver­si­ty and putting women in man­age­ment mat­ters. She brings an MD-PhD’s un­der­stand­ing of pa­tients, she said, and she took some­thing be­sides busi­ness acu­men back from her home­town of Rio de Janeiro: a cer­tain warmth.

“I’m from Brazil and Brazil­ians love to use hu­mor a lot,” Kapel­lar said.

For in­stance, she led off the com­pa­ny’s first meet­ing with their PR firm with a slide of her­self and her co-founders in Ro­man glad­i­a­tor cos­tumes. She’s re­luc­tant to men­tion those jokes in in­ter­views, though, weary af­ter enough years as an ex­ec­u­tive of how it might be trans­lat­ed.

With the sci­ence, she’s bold­er. They’re one of the first jump­ing in­to a still-emerg­ing field, she said, and their goal is sus­tained re­mis­sion: can­cer and au­toim­mune treat­ments that won’t stop work­ing af­ter a few months, or years.

This is “com­plete­ly un­chart­ed ter­ri­to­ry,” Kapeller said.

The DCT-OS: A Tech­nol­o­gy-first Op­er­at­ing Sys­tem - En­abling Clin­i­cal Tri­als

As technology-enabled clinical research becomes the new normal, an integrated decentralized clinical trial operating system can ensure quality, deliver consistency and improve the patient experience.

The increasing availability of COVID-19 vaccines has many of us looking forward to a time when everyday things return to a state of normal. Schools and teachers are returning to classrooms, offices and small businesses are reopening, and there’s a palpable sense of optimism that the often-awkward adjustments we’ve all made personally and professionally in the last year are behind us, never to return. In the world of clinical research, however, some pandemic-necessitated adjustments are proving to be more than emergency stopgap measures to ensure trial continuity — and numerous decentralized clinical trial (DCT) tools and methodologies employed within the last year are likely here to stay as part of biopharma’s new normal.

A 'fly­over' biotech launch­es in Texas with four Ron De­Pin­ho-found­ed com­pa­nies un­der its belt

In his 13 years at Genzyme, Michael Wyzga noticed something about East Coast drugmakers. Execs would often jet from Boston or New York to San Francisco to find more assets, and completely miss the work being done in flyover states, like Texas or Wisconsin.

“If it doesn’t come out of MGH or MIT or Harvard, probably not that interesting,” he said of the mindset.

Now, he and some well-known industry players are looking to change that, and they’ve reeled in just over $38 million to do it.

Gala­pa­gos chops in­to their pipeline, drop­ping core fields and re­or­ga­niz­ing R&D as the BD team hunts for some­thing 'trans­for­ma­tive'

Just 5 months after Gilead gutted its rich partnership with Galapagos following a bitter setback at the FDA, the Belgian biotech is hunkering down and chopping the pipeline in an effort to conserve cash while their BD team pursues a mission to find a “transformative” deal for the company.

The filgotinib disaster didn’t warrant a mention as Galapagos laid out its Darwinian restructuring plans. Forced to make choices, the company is ditching its IPF molecule ’1205, while moving ahead with a Phase II IPF study for its chitinase inhibitor ’4617.

Mod­er­na CEO brush­es off US sup­port for IP waiv­er, eyes more than $19B in Covid-19 vac­cine sales in 2021

Moderna is definitively more concerned with keeping pace with Pfizer in the race to vaccinate the world against Covid-19 than it is with Wednesday’s decision from the Biden administration to back an intellectual property waiver that aims to increase vaccine supplies worldwide.

In its first quarter earnings call on Thursday, Moderna CEO Stéphane Bancel shrugged off any suggestion that the newly US-backed intellectual property waiver would impact his company’s vaccine or bottom line. Still, the company’s stock price fell by about 9% in early morning trading.

OcuWho? Star deal­mak­er turned aes­thet­ics czar Brent Saun­ders flips back in­to biotech. But who’s he team­ing up with now?

Brent Saunders went on a tear of headline-blazing deals building Allergan, merging and rearranging a variety of big companies into one before an M&A pact with Pfizer blew up and sent him on a bout of biotech drug deals. That didn’t work so well, so under pressure, he got his buyout at AbbVie — which needed a big franchise like Botox. And it was no big surprise to see him riding the SPAC wave into a recent $1 billion-plus deal that left him in the executive chairman’s seat at an aesthetics outfit — now redubbed The Beauty Health Company — holding a big chunk of the equity.

'Chang­ing the whole game of drug dis­cov­ery': Leg­endary R&D vet Roger Perl­mut­ter leaps back in­to work as a biotech CEO

Roger Perlmutter needs no introduction to anyone remotely involved in biopharma. As the R&D chief first at Amgen and then Merck, he’s built a stellar reputation and a prolific career steering new drugs toward the market for everything from cancer to infectious diseases.

But for years, he’s also held a less known title: science partner at The Column Group, where he’s regularly consulted about the various ideas the VCs had for new startups.

Ad­comm splits slight­ly in fa­vor of FDA ap­prov­ing Chemo­Cen­tryx’s rare dis­ease drug

The FDA’s Arthritis Advisory Committee on Thursday voted 10 for and 8 against the approval of ChemoCentryx’s $CCXI investigational drug avacopan as a treatment for adults with a rare and serious disease known as anti-neutrophil cytoplasmic autoantibody (ANCA)-vasculitis.

The vote on whether the FDA should approve the drug was preceded by a split vote of 9 to 9 on whether the efficacy data support approval, and 10 to 8 that the safety profile of avacopan is adequate enough to support approval.

Gold­man Sachs jumps aboard Bain-backed 503(b) com­pound­ing phar­ma­cy with a $275M debt loan to sup­ply hos­pi­tals

Long the bane of the FDA’s existence, compounding pharmacies have seen a minor resurgence in the past year as short-term saviors for hospital drug shortages. Now, a 503(b) company specializing in hospital meds has earned a big backer to keep expanding its 200-drug strong portfolio.

Goldman Sachs and Owl Rock Capital Partners have doled out a $275 million debt loan to QuVa Pharma, a 503(b)-certified outsourcing facility providing compounded drugs to hospitals, the company said Thursday.
