Ken Song (RayzeBio)

Bare­ly two months af­ter un­veil­ing a new breed of ra­dio­phar­ma­ceu­ti­cals, Rayze­Bio brings to­tal haul to $150M

Just be­fore Ver­sant and ven­Bio of­fi­cial­ly took the wraps off Rayze­Bio with $45 mil­lion in launch mon­ey, Ken Song reached out to a few oth­er in­vestors “just to give them an overview.”

He wasn’t nec­es­sar­i­ly look­ing to raise mon­ey im­me­di­ate­ly, the CEO said. Where­as the Se­ries A came to­geth­er most­ly around the con­cept of a new ra­dio­phar­ma­ceu­ti­cal com­pa­ny, Rayze­Bio now had more de­tails and progress around its pipeline to il­lus­trate just what its plat­form can do. But the group — com­pris­ing some firms that were known for their crossover and pub­lic port­fo­lios — be­came so en­thused that, bare­ly two months lat­er, he has $105 mil­lion more to work with.

The plan is still to have at least one de­vel­op­ment can­di­date by the sec­ond half of 2021 and start the first clin­i­cal tri­als with­in a year of that.

“We can now def­i­nite­ly pros­e­cute in par­al­lel all of our pro­grams with­out need­ing to make re­source al­lo­ca­tion de­ci­sions due to lack of cap­i­tal,” he told End­points News.

Deb­o­rah Charych

With 13 now on the pay­roll and more set to join, Song al­so wooed Er­ic Bischoff, a col­league from his Metacrine days, to join as SVP of de­vel­op­ment and op­er­a­tions. Gary Li, the new­ly ap­point­ed head of bi­ol­o­gy and trans­la­tion­al med­i­cine, is tasked with get­ting the com­pounds ready for IND-en­abling stud­ies. Both join Song and Deb­o­rah Charych, co-founder and chief tech­nol­o­gy of­fi­cer, on the se­nior team.

RayzBio’s pro­grams, in­clud­ing the most ad­vanced one in mid-stage lead op­ti­miza­tion, have two parts: There are the pep­tide binders for a host of sol­id tu­mor tar­gets, iden­ti­fied in screen­ing by its Japan­ese part­ners at Pep­tiDream. These are then ra­di­o­la­beled with Ac­tini­um-225 with the in­tent of send­ing the pow­er­ful ra­dioiso­tope straight, and on­ly, to can­cer cells.

The biotech’s de­ci­sion to make be­spoke binders rather than re­pur­pose mol­e­cules off-the-shelf proved ap­peal­ing to in­vestors, Song said. The VCs al­so liked that it had 7 pro­grams, some of which would be first-in-class ra­dio­phar­ma­ceu­ti­cal prod­ucts if they make it.

“Be­cause if you look at most oth­er ra­dio­phar­ma­ceu­ti­cal com­pa­nies that are out there — I’m ex­clud­ing No­var­tis, which is a large phar­ma — but if you look at pret­ty much every­one out there, most com­pa­nies are pur­su­ing maybe 1 or 2 pro­grams at most. And many of those pro­grams tend to be sort of the same tried and true tar­gets that have al­ready been pur­sued in ra­dio­phar­ma.”

A Ven­rock fund fo­cused on pub­licly held and late-stage pri­vate plays led the round, with Or­biMed, Red­mile Group, Viking Glob­al In­vestors, Lo­gos Cap­i­tal, Cor­morant As­set Man­age­ment, LifeSci Ven­ture Part­ners, Alexan­dria Ven­ture In­vest­ments and oth­ers join­ing as new in­vestors. Ver­sant and ven­Bio re­turned for more, along­side Sam­sara Bio­Cap­i­tal.

Bong Koh

Bong Koh from Ven­rock Health­care Cap­i­tal Part­ners is join­ing the board.

The new cash in­fu­sion will al­so fund an ex­pan­sion of the San Diego head­quar­ters as well as stud­ies in­to Rayze­Bio’s man­u­fac­tur­ing op­tions. Mak­ing ra­dioiso­tope-drug con­ju­gates, af­ter all, is a much dif­fer­ent process than typ­i­cal ther­a­pies, de­spite dra­mat­ic ad­vances in the abil­i­ty for ear­ly-stage de­vel­op­ers to se­cure ther­a­peu­tic ra­dioiso­topes.

For now, it’s go­ing with a cen­tral­ized mod­el re­ly­ing on key part­ners. But it could bring more of it in-house in the fu­ture — or try some­thing else.

“I would say every­thing is still on the ta­ble in terms of de­ter­min­ing what is the best man­u­fac­tur­ing strat­e­gy to take for­ward,” Song said.

The Fac­tors Dri­ving a Rapid Evo­lu­tion of Gene & Cell Ther­a­py and CAR-T Clin­i­cal Re­search in APAC

APAC is the fastest growing region globally for cell & gene therapy trials representing more than a third of all cell & gene studies globally, with China leading in the region. 

APAC is the leading location globally for CAR-T trials with China attracting ~60% of all CAR-T trials globally between 2015-2022. The number of CAR-T trials initiated by Western companies has rapidly increased in recent years (current CAGR of about 60%), with multiple targets being explored including CD19, CD20, CD22, BCMA, CD30, CD123, CD33, CD38, and CD138.

EMA warns of short­ages of two Boehringer heart drugs due to a spike in de­mand

The EMA is putting EU member states on alert over the shortage of two drugs that counter heart attacks due to an uptick in demand.

On Friday, the EMA sent out a warning that two Boehringer Ingelheim drugs are experiencing a shortage: Actilyse and Metalyse. The drugs are used as emergency treatments for adults experiencing acute myocardial infarction, or a heart attack, by dissolving blood clots that have formed in the blood vessels.

The End­points 11: The top pri­vate biotechs in pur­suit of new drugs. Push­ing the en­ve­lope with pow­er­ful new tech­nolo­gies

Right around the beginning of the year, we got a close-up look at what happens after a boom ripples through biotech. The crash of life sciences stocks in Q1 was heard around the world.

In the months since, we’ve seen the natural Darwinian down cycle take effect. Reverse mergers made a comeback, with more burned out shells to go public at a time IPOs and road shows are out of favor. And no doubt some of the more recent arrivals on the investing side of the business are finding greener pastures.

As­traZeneca, Mer­ck cull one Lyn­parza in­di­ca­tion in heav­i­ly pre­treat­ed ovar­i­an can­cer pa­tients

Just one day after blockbuster Lynparza got access to another indication in China, its Big Pharma owners have decided to withdraw it in certain patients after reviewing Phase III data.

The two companies that work together on Lynparza decided to recall one of the indications several weeks ago in a specific type of ovarian cancer, Lynparza’s first indication when it was first FDA-approved in 2014. Initial data showed that rates of overall survival in patients with at least three rounds of chemo before getting on the PARP inhibitor were lower than in patients with less previous chemo treatment.

Fu­ji­film con­tin­ues CD­MO ex­pan­sion, break­ing ground on $435M UK site

Fujifilm’s CDMO arm, Fujifilm Diosynth, has been on a roll this month as the company has recently broken ground on a major project in Europe and it appears to be keeping up the momentum.

Fujifilm Diosynth announced that it has kicked off an expansion project for its microbial manufacturing facility at its campus in the town of Billingham, UK, in the northeast of England.

The 20,000 square-foot, £400 million ($435 million) expansion will add clean rooms, purification suites and a packing area along with more space for the manufacturing itself.

Solicitor General Elizabeth Prelogar

Should SCO­TUS hear Am­gen's Repatha case? So­lic­i­tor gen­er­al says no

Back in April, Amgen said it was encouraged by the solicitor general’s anticipated review of its Supreme Court petition to rehear a Repatha patent case. They’re likely much less optimistic about the outcome now.

Solicitor General Elizabeth Prelogar wrote in a recent 27-page brief that Amgen’s arguments “lack merit and further review is not warranted.”

The case traces back to a suit filed in 2014 against Sanofi and Regeneron’s Praluent, which ended up beating Amgen’s PCSK9 blockbuster Repatha to market by a month just a year later.

The End­points 11: Fire­side chat with No­bel Prize lau­re­ate Phil Sharp

The following Q&A has been edited for length and clarity.

John Carroll:

We’ve had a chance to talk a little bit before here about some of the things that you’ve done. Just really remarkably, a lot of the things that you’ve done early in your career puts you in the path with some amazing science that has had an absolutely huge impact in terms of what we’re seeing now on drug development and some of the new technologies that are coming out here, and not only the new technologies, but also some of the most remarkable people ever.

Klick Health gath­ers biotech and phar­ma lu­mi­nar­ies to dis­cuss in­dus­try in­no­va­tions, in­vest­ments and fu­ture

At Klick Health’s first Ideas Exchange conference with biotech and pharma industry insiders since before the pandemic began, it was no surprise many conversations included Covid topics. Yet while vaccines and treatments were discussed, so too were the effects on drug development, federal responses, health inequities — and what to do now and next.

George Yancopoulos, chief scientist and cofounder of Regeneron, opened the conference responding to a question from Acorda CEO Ron Cohen about the spotlight on the industry during Covid and some of the “flak” biopharma has taken in the past.
