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.

The top career staff at the FDA have vowed not to let politics get in the way of science when looking at vaccine data this fall. But Alex Azar, who happens to be their boss’s boss, apparently won’t even give them a chance to stand in the way.

In a new memorandum issued Tuesday last week, the HHS chief stripped health agencies under his purview — including the FDA — of their rulemaking ability, asserting all such power “is reserved to the Secretary.” Sheila Kaplan of the New York Times first obtained and reported the details of the September 15 bulletin.

J&J’s one-two punch on EGFR-mutant non-small cell lung cancer has turned up some promising — although decidedly early — results, fueling the idea that there’s yet room to one up on third-generation tyrosine kinase inhibitors.

Twenty out of 20 advanced NSCLC patients had a response after taking a combination of an in-house TKI dubbed lazertinib and amivantamab, a bispecific antibody targeting both EGFR and cMET engineered on partner Genmab’s platform, J&J reported at ESMO. All were treatment-naïve, and none has seen their cancer progress at a median follow-up of seven months.

AstraZeneca has unveiled the final, mature overall survival data that cemented Lynparza’s first approval in prostate cancer approval — touting its lead against rivals with the only PARP inhibitor to have demonstrated such benefit.

But getting the Merck-partnered drug to the right patients remains a challenge, something the companies are hoping to change with the new data cut.

The OS numbers on the subgroup with BRCA1/2 or ATM-mutated metastatic castration-resistant prostate cancer are similar to the first look on offer when the FDA expanded the label in May: Lynparza reduced the risk of death by 31% versus Xtandi and Zytiga. Patients on Lynparza lived a median of 19.1 months, compared to 14.7 months for the anti-androgen therapies (p = 0.0175).

Late in August, as negotiations on a pricing deal with President Trump reached a boiling point, PhRMA president Stephen Ubl sent an email update to the 34 biopharma chiefs that sit on his board. He wrote that if the industry did not agree to pay for a $100 “cash card” sent to seniors before November, White House chief of staff Mark Meadows was going to tell the news media Big Pharma was refusing to “share the savings” with the elderly — and that all of the blame for failed drug pricing negotiations would lie squarely on the industry.
