There’s no sign that the wind­fall of cash drop­ping biotech’s way on Wall Street is abat­ing. Three more bio­phar­mas priced IPOs on Thurs­day and Fri­day morn­ing, rid­ing a his­toric boom with a $364 mil­lion pay­off.

Lon­don-based biotech Free­line Ther­a­peu­tics took home the li­on’s share of the cash with $159 mil­lion af­ter pric­ing 8,823,529 shares at $18 a pop. Check­mate Phar­ma­ceu­ti­cals, of Cam­bridge, MA, raised $75 mil­lion with an of­fer of 5 mil­lion shares at $15 — right at the mid­point of its range. And Arya Sci­ences Ac­qui­si­tion Corp III, the third in a se­ries from Per­cep­tive, priced 13,000,000 shares at $10 per share.

Drug­mak­ers are se­cur­ing big sums amid the pan­dem­ic boom, in­clud­ing AlloVir, which bagged $276 mil­lion from 16.3 mil­lion shares last week. Ini­tial­ly, the com­pa­ny had filed for a $100 mil­lion IPO. By June, all 23 new­ly pub­lic com­pa­nies had priced above their mid­point or up­sized their of­fer­ing.

And there’s more com­ing: Kymera Ther­a­peu­tics an­nounced plans to go pub­lic on Mon­day, when it filed for a $100 mil­lion IPO.

Check­mate ini­tial­ly filed for an IPO on Ju­ly 17, then raised its max­i­mum of­fer­ing price to $92 mil­lion in an amend­ed S-1 fil­ing. The im­muno-on­col­o­gy biotech is in­ves­ti­gat­ing its drug CMP-001 across mul­ti­ple can­cers, in­clud­ing melanoma and head and neck squa­mous cell car­ci­no­ma (HN­SCC), and says it will use the funds to ad­vance clin­i­cal tri­als. Bo­fA Se­cu­ri­ties, Jef­feries Group and BMO Cap­i­tal Mar­kets are man­ag­ing the deal.

CMP-001 us­es the im­mune sys­tem to its ad­van­tage, di­rect­ing ac­ti­vat­ed an­ti-tu­mor T cells to at­tack both the in­ject­ed tu­mor and tu­mors through­out the body. It’s been test­ed on more than 200 melanoma pa­tients to date, and based on clin­i­cal da­ta, the com­pa­ny be­lieves “there is an op­por­tu­ni­ty for CMP-001 to be de­vel­oped as a dif­fer­en­ti­at­ed im­muno-on­col­o­gy ther­a­py,” ac­cord­ing to the S-1 fil­ing.

Free­line ini­tial­ly filed for a $100 mil­lion IPO, with JP Mor­gan Se­cu­ri­ties LLC, Mor­gan Stan­ley & Co. and Ever­core Group as joint bookrun­ners. Its AAV gene-ther­a­py treat­ments tar­get he­mo­phil­ia A and B, Fab­ry dis­ease, and Type 1 Gauch­er dis­ease.

The biotech’s lead can­di­date, FLT180a, is cur­rent­ly in a Phase I/II tri­al for he­mo­phil­ia B. IPO funds will pro­pel the com­pa­ny’s pipeline, in­clud­ing Phase I/II tri­als for FLT180a and FLT190, a po­ten­tial drug to treat Fab­ry dis­ease.

SPACs (spe­cial pur­pose ac­qui­si­tion com­pa­nies) are ben­e­fit­ing from the boom, too. Once rare in the biotech world, they now rep­re­sent near­ly 35% of list­ings, Nas­daq’s Jay Heller told End­points last month.

Per­cep­tive Ad­vi­sors’ blank check com­pa­ny Arya III filed for a $143.7 mil­lion IPO on Ju­ly 21, and in­vestors are bet­ting on a prof­itable merg­er. In March, Arya I merged with biotech Im­mat­ics in a $252 mil­lion deal. Cerev­el Ther­a­peu­tics merged with Arya II in Ju­ly, ex­pect­ing to raise about $445 mil­lion to de­vel­op its pipeline.

You’ll be able to find all the biotechs that have filed and priced so far this year, sortable by quarter and listed by newest first. As of the time of publishing on Feb. 25, there have already been 16 biotechs debuting on Nasdaq so far this year, with an additional four having filed their S-1 paperwork.

The FDA adcomm has advanced to the free-for-all question stage of the hearing and, as they did for Moderna and Pfizer, committee members are raising questions about the lingering issues surrounding the vaccine.

In J&J’s case, one of those unknowns is a group of participants who appeared to respond worse to the vaccine: those over 60 with comorbidities. In that group, the vaccine was only 42% effective at stopping disease starting 28 days after vaccination.

Genentech has committed $53 million to back a 10-year quest aimed at going back to the drawing board to use new technology and fresh scientific insights to generate a pipeline of drugs for neurological diseases.

Roche’s big South San Francisco hub will mix it up with the scientists drawn together for the Weill Neurohub — formed in 2019 as a joint research partnership involving UCSF, Berkeley and the University of Washington — in an exploration of the field to develop new therapies for some of the toughest diseases in drug R&D: Alzheimer’s, Parkinson’s, Huntington’s, ALS and autism.

On the hunt for a novel competitor to Sanofi and Regeneron’s Dupixent in severe asthma, Amgen and AstraZeneca posted “exciting” results from their next-gen antibody late last year. Now, the partners are showing their hands, and the results look good enough for approval.

Amgen and AstraZeneca’s tezepelumab plus standard of care cut the rate of severe asthma attacks by 56% at the one-year mark compared with SOC alone, according to full data from the Phase III NAVIGATOR study presented Friday at the virtual American Academy of Allergy, Asthma & Immunology meeting. And those significant results were consistent regardless of patients’ baseline eosinophil counts.
