Luca Santarelli, VectivBio CEO

Lu­ca Santarel­li's Vec­tivBio buys out small Mass­a­chu­setts biotech, re­dou­bling fo­cus on meta­bol­ic dis­ease

Lu­ca Santarel­li moved quick­ly af­ter spin­ning out Vec­tivBio from Ther­a­chon, get­ting an IPO set­tled in less than two years. On Tues­day, he con­tin­ued charg­ing for­ward with a new buy­out that will see Vec­tivBio ex­pand its pipeline sig­nif­i­cant­ly over the next year and a half.

Vec­tivBio has ac­quired Comet Ther­a­peu­tics for an undis­closed eq­ui­ty and cash sum, the biotech an­nounced Tues­day, aim­ing to tar­get a swath of rare meta­bol­ic dis­eases. The goal is to hit the ground run­ning, Santarel­li told End­points News, with four new pro­grams ex­pect­ed to launch at once and plans to en­ter the clin­ic in 18 months.

“This deal is im­por­tant for us but al­so some­thing we’ve been plan­ning for a long time,” Santarel­li told End­points.

In ad­di­tion to the sums paid up­front, Vec­tivBio could be on the hook for more eq­ui­ty and cash pay­ments should the new projects reach cer­tain mile­stones.

As their teams start work­ing to­geth­er, Vec­tivBio and Comet will go af­ter a fam­i­ly of con­di­tions known as in­her­it­ed meta­bol­ic dis­eases, or IMDs. These ge­net­ic dis­or­ders re­sult in in­fants be­ing un­able to prop­er­ly con­vert food in­to en­er­gy, re­sult­ing in the buildup of tox­ic metabo­lites and some­times life-threat­en­ing con­di­tions that have lim­it­ed treat­ment op­tions.

Comet, how­ev­er, has de­vel­oped a plat­form to at­tack these dis­eases with a “unique” bit of chem­istry, Santarel­li said. By fo­cus­ing on coen­zyme A, an en­zyme im­pli­cat­ed in many meta­bol­ic path­ways, re­searchers the­o­rized a way to re­store its nor­mal func­tion while de­liv­er­ing pay­loads spe­cif­ic to each IMD.

“It al­lows CoA to be used as a back­bone,” Santarel­li said of the Comet tech­nol­o­gy. “It al­lows for sys­temic ad­min­is­tra­tion and ex­po­sure, al­lows for sys­temic in­te­gra­tion and can car­ry var­i­ous car­goes in­to the cells.”

The first pro­gram that will come out of the ac­qui­si­tion will tar­get or­gan­ic acid dis­or­ders such as methyl­malonic acidemia and pro­pi­onic acidemia, Santarel­li added. Their goal is to de­liv­er car­go that can stim­u­late the dis­reg­u­lat­ed meta­bol­ic path­ways.

Vec­tivBio got start­ed back in 2019, spin­ning out from Ther­a­con af­ter Pfiz­er bought it out for $340 mil­lion up­front and $470 mil­lion in po­ten­tial mile­stones. The biotech al­most im­me­di­ate­ly got to work on a Phase II drug for short bow­el syn­drome, and Santarel­li raised $110 mil­lion last Oc­to­ber to get the pro­gram through Phase III.

He fol­lowed that up with an IPO ear­li­er this year, and the com­pa­ny is ex­pect­ing topline re­sults for SBS in­testi­nal fail­ure in 2023. But with the Comet ac­qui­si­tion Tues­day, Santarel­li is start­ing work on Vec­tivBio’s next chap­ter in the mean­time.

Comet launched back in 2018 and re­ceived $28.5 mil­lion in a Se­ries A in June 2019. The Cam­bridge, MA-based biotech has seen in­vest­ment from Sofinno­va Part­ners, INKEF Cap­i­tal, Canaan and Mis­sion Bio­Cap­i­tal.

ZS Per­spec­tive: 3 Pre­dic­tions on the Fu­ture of Cell & Gene Ther­a­pies

The field of cell and gene therapies (C&GTs) has seen a renaissance, with first generation commercial therapies such as Kymriah, Yescarta, and Luxturna laying the groundwork for an incoming wave of potentially transformative C&GTs that aim to address diverse disease areas. With this renaissance comes several potential opportunities, of which we discuss three predictions below.

Allogenic Natural Killer (NK) Cells have the potential to displace current Cell Therapies in oncology if proven durable.

Despite being early in development, Allogenic NKs are proving to be an attractive new treatment paradigm in oncology. The question of durability of response with allogenic therapies is still an unknown. Fate Therapeutics’ recent phase 1 data for FT516 showed relatively quicker relapses vs already approved autologous CAR-Ts. However, other manufacturers, like Allogene for their allogenic CAR-T therapy ALLO-501A, are exploring novel lymphodepletion approaches to improve persistence of allogenic cells. Nevertheless, allogenic NKs demonstrate a strong value proposition relative to their T cell counterparts due to comparable response rates (so far) combined with the added advantage of a significantly safer AE profile. Specifically, little to no risk of graft versus host disease (GvHD), cytotoxic release syndrome (CRS), and neurotoxicity (NT) have been seen so far with allogenic NK cells (Fig. 1). In addition, being able to harness an allogenic cell source gives way to operational advantages as “off-the-shelf” products provide improved turnaround time (TAT), scalability, and potentially reduced cost. NKs are currently in development for a variety of overlapping hematological indications with chimeric antigen receptor T cells (CAR-Ts) today, and the question remains to what extent they will disrupt the current cell therapy landscape.

A $3B+ peak sales win? Pfiz­er thinks so, as FDA of­fers a tardy green light to its JAK1 drug abroc­i­tinib

Back in the fall of 2020, newly crowned Pfizer chief Albert Bourla confidently put their JAK1 inhibitor abrocitinib at the top of the list of blockbuster drugs in the late-stage pipeline with a $3 billion-plus peak sales estimate.

Since then it’s been subjected to serious criticism for the safety warnings associated with the class, held back by a cautious FDA and questioned when researchers rolled out a top-line boast that their heavyweight contender had beaten the champ in the field of atopic dermatitis — Dupixent — in a head-to-head study.

Rob Califf ad­vances as Biden's FDA nom­i­nee, with a close com­mit­tee vote

Rob Califf’s second confirmation process as FDA commissioner is already much more difficult than his near unanimous confirmation under the Obama administration.

The Senate Health Committee on Thursday voted 13-8 in favor of advancing Califf’s nomination to a full Senate vote. Several Democrats voted against Califf, including Sen. Bernie Sanders and Sen. Maggie Hassan. Several other Democrats who aren’t on the committee, like West Virginia’s Joe Manchin and Ed Markey of Massachusetts, also said Thursday that they would not vote for Califf. Markey, Hassan and Manchin all previously expressed reservations about the prospect of Janet Woodcock as an FDA commissioner nominee too.

Bio­gen vows to fight CM­S' draft cov­er­age de­ci­sion for Aduhelm be­fore April fi­nal­iza­tion

Biogen executives made clear in an investor call Thursday they are not preparing to run a new CMS-approved clinical trial for their controversial Alzheimer’s drug anytime soon.

As requested in a draft national coverage decision from CMS earlier this week, Biogen and other anti-amyloid drugs will need to show “a meaningful improvement in health outcomes” for Alzheimer’s patients in a randomized, placebo-controlled trial to get paid for their drugs, rather than just the reduction in amyloid plaques that won Aduhelm its accelerated approval in June.

CRO own­er pleads guilty to ob­struct­ing FDA in­ves­ti­ga­tion in­to fal­si­fied clin­i­cal tri­al da­ta

The co-owner of a Florida-based clinical research site pleaded guilty to lying to an FDA investigator during a 2017 inspection, revealing that she falsely portrayed part of a GlaxoSmithKline pediatric asthma study as legitimate, when in fact she knew that certain data had been falsified, the Department of Justice said Wednesday.

Three other employees — Yvelice Villaman Bencosme, Lisett Raventos and Maytee Lledo — previously pleaded guilty and were sentenced in connection with falsifying data associated with the trial at the CRO Unlimited Medical Research.

Can­cer pow­er­house As­traZeneca rolls the dice on a $75M cash bet on a buzzy up­start in the on­col­o­gy field

After establishing itself in the front ranks of cancer drug developers and marketers, AstraZeneca is putting its scientific shoulder — and a significant amount of cash — behind the wheel of a brash new upstart in the biotech world.

The pharma giant trumpeted news this morning that it is handing over $75 million upfront to ally itself with Scorpion Therapeutics, one of those biotechs that was newly birthed by some top scientific, venture and executive talent and bequeathed with a fortune by way of a bankroll to advance an only hazily explained drug platform. And they are still very much in the discovery and preclinical phase.

‘Skin­ny la­bels’ on gener­ics can save pa­tients mon­ey, re­search shows, but re­cent court de­ci­sions cloud fu­ture

New research shows how generic drug companies can successfully market a limited number of approved indications for a brand name drug, prior to coming to market for all of the indications. But several recent court decisions have created a layer of uncertainty around these so-called “skinny” labels.

While courts have generally allowed generic manufacturers to use their statutorily permitted skinny-label approvals, last summer, a federal circuit court found that Teva Pharmaceuticals was liable for inducing prescribers and patients to infringe GlaxoSmithKline’s patents through advertising and marketing practices that suggested Teva’s generic, with its skinny label, could be employed for the patented uses.

How a tiny Swiss lab and two old blood sam­ples cre­at­ed one of the on­ly ef­fec­tive drugs against Omi­cron (and why we have so lit­tle of it)

Exactly a decade before a novel coronavirus broke out in Wuhan, Davide Corti — a newly-minted immunologist with frameless glasses and a quick laugh — walked into a cramped lab on the top floor of an office building two hours outside Zurich. He had only enough money for two technicians and the ceiling was so low in parts that short stature was a job requirement, but Corti believed it’d be enough to test an idea he thought could change medicine.
