How much does it cost to boot­strap a gene ther­a­py start­up? Not too much if you're Jim Wil­son, per Pas­sage Bio's $125M IPO fil­ing

Days ago when Deer­field part­ner Bruce Gold­smith jumped to helm Pas­sage Bio, he cit­ed a few rea­sons why it’s an “ex­treme­ly ex­cit­ing time” to be join­ing the gene ther­a­py play­er: IND fil­ings for three lead pro­grams, a da­ta-rich 2021 and an ex­pand­ing pipeline of ex­per­i­men­tal drugs for rare, mono­genic CNS dis­eases.

It turns out there’s one more rea­son he held back: The Philadel­phia-based start­up was prep­ping an IPO.

Pas­sage Bio has pen­ciled in $125 mil­lion for its pub­lic de­but on the Nas­daq, with the ma­jor­i­ty of the pro­ceeds go­ing to the three AAV-based prod­uct can­di­dates slat­ed to en­ter the clin­ic in 2020.

Here’s the break­down on the tech be­hind each of them — of­fer­ing a glimpse of the ar­se­nal of de­liv­ery tools co-founder Jim Wil­son has as­sem­bled over the decades:

  1. PBGM01 uti­lizes a next-gen­er­a­tion AAVhu68 cap­sid to de­liv­er to the brain and pe­riph­er­al tis­sues a func­tion­al GLB1 gene en­cod­ing lyso­so­mal be­ta-galac­tosi­dase, or b-gal, for in­fan­tile GM1 gan­gliosi­do­sis
  2. PBFT02 uti­lizes an AAV1 cap­sid to de­liv­er to the brain a func­tion­al GRN gene en­cod­ing pro­gran­ulin, or PGRN, for FTD caused by pro­gran­ulin de­fi­cien­cy, or FTD-GRN
  3. PBKR03 uti­lizes a next-gen­er­a­tion AAVhu68 cap­sid to de­liv­er to the brain and pe­riph­er­al tis­sues a func­tion­al gene en­cod­ing the hy­drolyt­ic en­zyme galac­to­syl­ce­rami­dase, or GALC, for in­fan­tile Krabbe dis­ease

There are some com­peti­tors work­ing on each of the dis­eases they are tack­ling, in­clud­ing Ax­o­vant and Lyso­gene for GM1 as well as Alec­tor and Pre­vail for FTD, but Pas­sage Bio was con­fi­dent about be­ing an in­te­grat­ed play­er ca­pa­ble of tack­ling mul­ti­ple “cross-cor­rec­tion­al ther­a­pies” in the CNS.

Wil­son, a well-re­spect­ed pi­o­neer in the gene ther­a­py field, had in­tend­ed for this to be his lega­cy com­pa­ny, Or­biMed part­ner Stephen Squin­to pre­vi­ous­ly told End­points News. Thanks to Wil­son’s con­nec­tion at the Uni­ver­si­ty of Penn­syl­va­nia, Pas­sage se­cured a li­cens­ing deal with the uni­ver­si­ty for an up­front of just $2.5 mil­lion in cash and 3,720,000 shares in stock (then val­ued at $0.9 mil­lion) — plus a promise to fund cer­tain pre­clin­i­cal ac­tiv­i­ties, the S-1 re­vealed.

The pact cov­ered rights to 12 ther­a­pies in to­tal, and should Pas­sage ex­er­cise those op­tions by the 2022 ex­piry date, up­front fees would be some­where be­tween $0.8 mil­lion to $1 mil­lion. They have al­ready made the call on six; Penn is el­i­gi­ble for up to $16.5 mil­lion in de­vel­op­ment mile­stones and $55 mil­lion in sales mile­stones for each.

That, plus the $10 mil­lion up­front Pas­sage paid Catal­ent’s Paragon sub­sidiary for man­u­fac­tur­ing work, amount­ed to the bulk of the biotech’s ex­pense. While it’s bagged two hefty megarounds, Pas­sage has on­ly burned through $58.7 mil­lion so far.

The syn­di­cate stayed ba­si­cal­ly the same through­out Se­ries A and B, fea­tur­ing Fra­zier Life Sci­ences (13.9%, rep­re­sent­ed by Wil­son’s long­time men­tor Tachi Ya­ma­da on the board), Or­biMed (19.6%), Ver­sant Ven­tures (14.8%) Lil­ly Asia Ven­tures (7.6%), New Leaf Ven­tures (7.0%), Vi­vo Cap­i­tal (7.0%) and Ac­cess In­dus­tries’ AI Pas­sage (6.5%). Wil­son re­tained 7.0% for him­self.

With his rare dis­ease ex­pe­ri­ence gleaned from years at Alex­ion, Squin­to ini­tial­ly took up the CEO role be­fore pass­ing the reins to Gold­smith. His com­pen­sa­tion pack­age for the past year to­taled $2.2 mil­lion com­pen­sa­tion, and he con­tin­ues to be part of the team as in­ter­im head of R&D.

Chief tech­ni­cal of­fi­cer Alex Fo­topou­los and chief med­ical of­fi­cer Gary Ro­mano re­ceived $2.25 mil­lion and $2.02 mil­lion, re­spec­tive­ly.

UP­DAT­ED: Am­gen snaps up can­cer drug play­er Five Prime, adding PhI­II-ready FGFR2b drug in $2B M&A play

Amgen is making a long-awaited move on the M&A side, buying South San Francisco-based Five Prime $FPRX for close to $2 billion and adding a slate of new cancer drugs to the pipeline.

Amgen is paying $38 a share, putting the deal value at $1.9 billion. The stock closed at $21.26 last night, giving investors a 78% premium.

The jewel in the crown of this deal is bemarituzumab, which Amgen describes as a first-in-class, Phase III-ready anti-FGFR2b antibody. Amgen was drawn to the bargaining table by Five Prime’s mid-stage data on gastric cancer, satisfied by PFS and OS data helping to validate FGFR2b as a target. Amgen researchers will now expand on the R&D program in other epithelial cancers, including lung, breast, ovarian and other cancers.

UP­DAT­ED: Not 3 weeks af­ter tak­ing Hu­ma­cyte pub­lic, Ra­jiv Shuk­la launch­es an­oth­er blank check com­pa­ny

One of biotech’s earliest SPAC investors is back with another blank-check company, less than a month after his last effort announced its intent to merge.

Rajiv Shukla is intending to take a third lucky winner public with Alpha Healthcare Acquisition III, filing to go public Thursday with a $150 million raise penciled in. The move comes just a couple of weeks after Shukla’s second SPAC said it would jump to Nasdaq in tandem with Laura Niklason’s Humacyte in a $255 million new investment.

David Liu has a new big idea: pro­teome edit­ing. It could one day shred tau, RAS and some of the worst dis­ease-caus­ing pro­teins

Before David Liu became famous for inventing new forms of gene editing, he was known around academia in part for a more obscure innovation: a Rube Goldberg-esque system that uses bacteria-infecting viruses to take one protein and turn it into another.

Since 2011, Liu’s lab has used the system, called PACE, to dream up fantastical new proteins: DNA base editors far more powerful than the original; more versatile forms of the gene editor Cas9; insecticides that kill insecticide-resistant bugs; enzymes that slide synthetic amino acids into living organisms. But they struggled throughout to master one of the most common and powerful proteins in the biological world: proteases, a set of Swiss army knife enzymes that cut, cleave or shred other proteins in everything from viruses to humans.

Bruce Cozadd, Jazz CEO (Jazz Pharmaceuticals)

Jazz CEO Bruce Cozadd cam­paigned for 6 months to buy GW Phar­ma. A 90% pre­mi­um sealed the deal — along with $17.6M in ‘re­ten­tion’ in­cen­tives

Jazz CEO Bruce Cozadd didn’t beat around the bush.

In his first video meeting with GW Pharma chief Justin Gover last July 8, he offered to pay $172 a share to get the company, which had beaten the odds in getting its remarkable cannabinoid drug Epidiolex across the regulatory finish line for epilepsy. GW’s stock closed at $129 that day.

Cozadd had already done his homework on the financing to make sure he could swing it the way he wanted. He just needed to do some due diligence before making the non-binding bid firm.

How does Paul Hud­son's $13.5M comp pack­age stack up against oth­er CEOs? He's in the 'first quar­tile'

Paul Hudson arrived at Sanofi like a hurricane, chopping off duds in the pipeline, shaking up the C-suite, striking big M&A deals and jumping into the Covid-19 vaccine race — all in an attempt to reboot a pharma giant notorious for its setbacks.

Now, we’re getting a look at what the CEO brought home in his first year on the job.

When all is said and done, Hudson will have made about $6.7 million in 2020, about $2.5 million of which has already been paid. The bigger figure includes a $2.3 million bonus that’s subject to approval at an April meeting, and another $1.8 million in variable compensation that has yet to be paid.

Ab­b­Vie of­floads UK site for $119M in sale to Chi­nese cell and gene ther­a­py play­er Phar­maron

With its Allergan buyout now long in the books, AbbVie has been taking a hard look at its suddenly expansive global ops to find space for a deal. Now, working with a Chinese cell and gene therapy player hungry for more elbow room abroad, AbbVie has taken one UK facility off its books.

AbbVie has offloaded its Liverpool manufacturing site as part of a $118.7 million sale to Chinese cell and gene therapy player Pharmaron, which is pitching the purchase as the next step in its global expansion plans, the companies said last week.

An Ar­ray co-founder re-emerges as CEO of a small aca­d­e­m­ic spin­out, look­ing to re­make an old class of can­cer drugs

Tony Piscopio hadn’t worked as a bench scientist in years when, around 2011, he got put in touch with a team at the University of Colorado trying to revitalize an old approach to treating cancer.

Piscopio, who had co-founded Array Biopharma before heading to South Korea to launch a new company, was back in the states, unattached and intrigued. He founded a three-person company with two professors, Xuedong Liu and Gail Eckhardt, and while they worked on the biology side, he returned to his old chemist chair and began drawing up potential compounds on a computer, along with manufacturing processes to make them. Outsourcing companies synthesized or analyzed the results.
