Can a Nek­tar ri­val make it on Nas­daq with a $100M IPO? Syn­thorx is giv­ing it a shot

Af­ter all the hub­bub around Nek­tar’s sec­ond-gen take on a pe­gy­lat­ed IL-2, is Nas­daq ready for a ri­val that be­lieves it can do the whole field one bet­ter?

Syn­thorx, a pre­clin­i­cal biotech with pri­mate da­ta that was set up by Aval­on, has filed for a $100 mil­lion IPO — hop­ing to catch a wave of ex­cite­ment that has pro­pelled scores of S-1s this year for ear­ly-stage com­pa­nies.

Like Nek­tar, Syn­thorx start­ed out with the knowl­edge that Pro­leukin nev­er lived up to its in­cred­i­ble ini­tial promise in can­cer, large­ly be­cause of a bad tox pro­file high­light­ed by vas­cu­lar leak syn­drome. And the lit­tle biotech has been work­ing on its own al­ter­na­tive un­der the guid­ance of CEO Lau­ra Shawver, an ex­pe­ri­enced biotech vet.

Here’s the rel­e­vant sec­tion from the S-1 filed with the SEC:

Us­ing our Ex­pand­ed Ge­net­ic Al­pha­bet plat­form tech­nol­o­gy, we site-specif­i­cal­ly pe­gy­lat­ed IL-2 to in­vent THOR-707 for im­muno-on­col­o­gy, or IO. We have de­signed THOR-707 to kill tu­mor cells by in­creas­ing CD8+ T and NK cells with­out caus­ing VLS (vas­cu­lar leak syn­drome) that has been ob­served with aldesleukin. In our non-hu­man pri­mate…pre­clin­i­cal stud­ies THOR-707 at dos­es ten times high­er than the dos­es ob­served to max­i­mal­ly ex­pand CD8+ T cells in NHP did not re­sult in signs of VLS, as mea­sured by in­creas­es in eosinophil count and lung and liv­er weight. Pub­lished pre­clin­i­cal lit­er­a­ture shows that com­bin­ing IL-2 treat­ment with PD-1 in­hibitors could have syn­er­gis­tic ef­fects in en­hanc­ing CD8+ T cell re­spons­es. As a re­sult, we be­lieve that THOR-707 in com­bi­na­tion with im­mune check­point in­hibitors may have greater an­ti-tu­mor ef­fects than PD-1 in­hibitors alone with­out the VLS ob­served with aldesleukin.

There’s al­so an­oth­er IL-2 pro­gram that works in re­verse, pro­mot­ing reg­u­la­to­ry T cells that sup­press the im­mune sys­tem to the ad­van­tage of pa­tients suf­fer­ing from au­toim­mune dis­ease.

Nek­tar’s NK­TR-214 is spot­light­ed as the biggest ri­val in the clin­ic. But the S-1 al­so cites Roche’s RO6874281, which spurred 3 ob­jec­tive re­spons­es in an ear­ly study. That drug, they say, is sim­i­lar to their own. And there is al­so Alk­er­mes’ ALKS-4230, “where a por­tion of the al­pha re­cep­tor is at­tached to IL-2, which dis­ables al­pha bind­ing. In a Phase I study of ad­vanced sol­id tu­mors, no re­spons­es were ob­served in 24 pa­tients.”

Jay Lichter’s Aval­on still con­trols the largest batch of stock, with 32%, with Pe­ter Kolchin­sky at RA Cap­i­tal in for 28.2% and Or­biMed hold­ing 21.5%. Those are the big 3. Shawver her­self has a slight 1% of the eq­ui­ty. Tighe Rear­don, the CFO at Aval­on, has 6.5% of the shares.

'I re­al­ly don’t look back': Janet Wood­cock on her tran­si­tion away from drugs

Janet Woodcock may have one of the most historically long and drug-intense tenures in FDA history, but her new role is outside of all things pharma and the once-acting FDA commissioner isn’t looking back.

“No I really don’t look back,” Woodcock told Endpoints News via email on Monday morning. “Yes I will be transitioning. Longer discussion on infrastructure needed.”

Co­pay coupons gone wrong, again: Pfiz­er pays al­most $300K to set­tle com­plaints in four states

Pfizer has agreed to pay $290,000 to settle allegations of questionable copay coupon practices in Arizona, Colorado, Kansas, and Vermont from 2014 to 2018.

While the company has not admitted any wrongdoing as part of the settlement, Pfizer has agreed to issue restitution checks to about 5,000 consumers.

A Pfizer spokesperson said the company has “enhanced its co-pay coupons to alleviate the concerns raised by states and agreed to a $30,000 payment to each.”

Delaware court rules against Gilead and Astel­las in years-long patent case

A judge in Delaware has ruled against Astellas Pharma and Gilead in a long-running patent case over Pfizer-onwed Hospira’s generic version of Lexiscan.

The case kicked off in 2018, after Hospira submitted an Abbreviated New Drug Application (ANDA) for approval to market a generic version of Gilead’s Lexiscan. The drug is used in myocardial perfusion imaging (MPI), a type of nuclear stress test.

Idor­sia inks an­oth­er celebri­ty en­dors­er deal with ac­tor and dad Taye Dig­gs as Qu­viviq in­som­nia am­bas­sador

Idorsia’s latest Quviviq insomnia campaign details the relatable dad story of a well-known celebrity — actor and Broadway star Taye Diggs.

Diggs stopped sleeping well after the birth of his son, now more than 10 years ago. Switching mom-and-dad nightly shifts to take care of a baby interrupted his sleep patterns and led to insomnia.

“When you’re lucky enough to be living out your dream and doing what you want, but because of something as simple as a lack of sleep, you’re unable to do that, it felt absolutely — it was treacherous,” he says in an interview-style video on the Quviviq website.

Mer­ck KGaA pumps €440M in­to ex­pand­ing and con­struct­ing Irish man­u­fac­tur­ing fa­cil­i­ties

The area of Ireland famous for Blarney Castle and its cliffsides along the Atlantic Ocean is seeing Merck KGaA expand its commitment there.

The German drug manufacturer is expanding its membrane and filtration manufacturing capabilities in Ireland. The company will invest approximately €440 million ($470 million) to increase membrane manufacturing capacity in Carrigtwohill, Ireland, and build a new manufacturing facility at Blarney Business Park, in County Cork, Ireland.

House Dems to Sen­ate lead­er­ship: Quick­ly move a rec­on­cil­i­a­tion bill with drug price ne­go­ti­a­tion re­forms

Twenty House Democrats, including Reps. Katie Porter of California and Susan Wild of Pennsylvania, are calling on Senate leaders to move quickly with a reconciliation bill (meaning they only need a simple majority for passage) with prescription drug pricing reforms, and to include adding new authority for Medicare to negotiate drug prices.

They also called on the Senate to specifically follow suit with the House passage of a $35 per month insulin cap (as Senate Majority Leader Chuck Schumer’s deadline for a vote on that provision has come and gone), and to cap Medicare Part D costs at $2,000 per year for seniors.

An NYU surgeon transplants an engineered pig kidney into the outside of a brain-dead patient (Joe Carrotta/NYU Langone Health)

'Xeno­trans­plan­ta­tion is com­ing': New NE­JM pa­per gives de­tailed look in­to 2 pig-to-hu­man kid­ney trans­plant cas­es

The thymokidney is a curious organ, if you could call it that. It’s a sort of Frankensteinian creation — a system of pig thymus embedded underneath the outer layer of a pig’s kidney, made for human transplantation.

In the first case of pig-to-human xenotransplantation of a kidney into a brain-dead patient, the thymokidney quietly featured front and center.

In that experiment, which took place in September of last year, NYU researchers led by Robert Montgomery sutured a pig thymokidney onto the leg of a brain-dead 66-year-old woman. That case was widely reported on by a horde of major media outlets, including the New York Times, the BBC, and an in-depth feature by USA Today.

Phillip Gomez, SIGA CEO

UP­DAT­ED: On the back of SIGA Tech­nolo­gies' win with the FDA, the mon­key­pox virus sees the com­pa­ny spring­ing to fur­ther ac­tion

As the cases of monkeypox now sit at well over 100 worldwide and have spread to multiple continents, the orders for any type of vaccine against monkeypox are seeing nations and medical bodies looking to get their hands on anything and everything. And now SIGA Technologies seems to be getting in on the action.

According to Euronews, SIGA Technologies, a pharmaceutical company that is focused on providing medical countermeasures to biological and chemical attacks, is now in talks with several European authorities looking to stockpile its antiviral that can counter monkeypox. The drug known as tecovirimat or Tpoxx was approved by the FDA in 2018 as a vaccine for smallpox but was approved by the European Medicines Agency to also act against monkeypox, cowpox and complications from immunization with vaccinia.

Vlad Coric, Biohaven CEO

UP­DAT­ED: Fresh off $11.6B sale to Pfiz­er, New Bio­haven hits Phase III set­back just weeks af­ter Vlad Coric chalked up promise

When Pfizer bought up Biohaven’s migraine portfolio in the largest M&A deal of the year earlier this month, Biohaven CEO Vlad Coric promised the rest of the pipeline, which will live on under the umbrella of New Biohaven, still has a lot to offer. But that vision took a dent Monday as the drugmaker revealed it’s once again flopped on troriluzole.

The glutamate regulator failed to meet the primary endpoint on a Phase III study in patients with spinocerebellar ataxia, an inherited disorder that impairs a person’s ability to walk, speak and swallow. SCA can also lead to premature death.
