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.

In­fla­tion re­bates in­com­ing: Wyden calls on CMS to move quick­ly as No­var­tis CEO pledges re­ver­sal

Senate Finance Chair Ron Wyden (D-OR) this week sent a letter to the head of the Centers for Medicare & Medicaid Services seeking an update on how and when new inflation-linked rebates will take effect for drugs that see major price spikes.

The newly signed Inflation Reduction Act requires manufacturers to pay a rebate to Medicare when they increase drug prices faster than the rate of inflation.

Trodelvy notch­es a win in most com­mon form of breast can­cer

Following a promise last year to go “big and fast in breast cancer,” Gilead has secured a win for Trodelvy in the most common form.

The drug was approved to treat HR-positive, HER2-negative breast cancer patients who’ve already received endocrine-based therapy and at least two other systemic therapies for metastatic cancer, Gilead announced on Friday.

Trodelvy won its first indication in metastatic triple-negative breast cancer back in 2020, and has since added urothelial cancer to the list. HR-positive HER2-negative breast cancer accounts for roughly 70% of new breast cancer cases worldwide per year, according to senior VP of oncology clinical development Bill Grossman, and many patients develop resistance to endocrine-based therapies or worsen on chemotherapy.

Af­ter 13 years, Ramy Mah­moud steps in­to CEO seat at Opti­nose; Ru­pert Vessey set to ex­it Bris­tol My­ers in Ju­ly

After 13 years as president and COO at Optinose, Ramy Mahmoud has stepped into a new role as its CEO. He is taking the place of Peter Miller, who stepped down earlier this week, though Miller is still staying with the company as a consultant.

In 2010, the two business partners joined Optinose to take it in a new direction, transforming it from a delivery platform to product company. They previously worked together at Johnson & Johnson, when Miller was president at Janssen and Mahmoud headed medical affairs. Miller said after he learned about Optinose, “I did what I always do, which is find people smarter than me to talk with about the idea. And the first person I called was Ramy … and I said, ‘Hey, Ramy, what do you think of this technology?’”

Sanofi sees downtick in flu sales as it preps for launch of RSV an­ti­body

Sanofi expects its RSV antibody jointly developed with AstraZeneca will be available next season, executive VP of vaccines Thomas Triomphe announced on the company’s quarterly call.

Beyfortus, also known as nirsevimab, was approved in the EU back in November and is currently under FDA review with an expected decision coming in the third quarter of this year. The news comes as the FDA plans to hold advisory committee meetings over the next couple months to review RSV vaccines from Pfizer and GSK.

Take­da fo­cus­es on ‘di­verse’ pipeline prospects on heels of two ac­qui­si­tions

After a whopping $4 billion asset buy from Nimbus Therapeutics, along with a $400 million deal with Hutchmed for a colorectal cancer drug, Takeda executives touted pipeline optimism on its latest earnings call this week.

That’s because the TYK2 inhibitor for psoriasis Takeda is getting from Nimbus, along with the Hutchmed fruquintinib commercialization outside of China, are just two of what it reports are 10 late-stage development programs of promising candidates.

In show­down with Roche, Re­gen­eron gears up for po­ten­tial Eylea ex­pan­sion amid Covid de­cline

Regeneron faced a substantial slump in overall revenue last year, but the focus still remains on some of its biggest blockbusters.

The pharma with several high-profile partnerships — Sanofi and Bayer among them — said Friday that Q4 revenue was down 31% for the quarter, and down 24% for the entire year. However, that won’t stop blockbuster expansion plans.

One of those is Eylea, the Bayer-partnered eye disease drug that has been in major competition with Roche’s Vabysmo. While Eylea is currently only approved in a 2 mg dose, the company recently filed for approval to give a 8 mg dose, in hopes of making a longer-lasting treatment.
