Bil­lion­aire-backed Park­er In­sti­tute tack­les the Holy Grail of can­cer R&D — with a vir­tu­al un­known

Up un­til about 6 months ago, Fred Rams­dell, the vice pres­i­dent for re­search at the Park­er In­sti­tute for Can­cer Im­munother­a­py, had nev­er heard of Tes­sa Ther­a­peu­tics. But he and some of the top can­cer re­searchers as­so­ci­at­ed with the Park­er In­sti­tute’s far flung net­work of in­ves­ti­ga­tors have been mak­ing up for lost time.

Fred Rams­dell

The Park­er In­sti­tute — fund­ed by tech mogul Sean Park­er — is an­nounc­ing Mon­day that it is mak­ing a leap in­to next-gen adop­tive cell ther­a­pies for can­cer, join­ing with Sin­ga­pore-based Tes­sa. Their new biotech al­ly is now en­gaged in a Phase III tri­al that hopes to open a new chap­ter in the field, look­ing to share the spot­light with the lead­ers which have dom­i­nat­ed the im­munother­a­py are­na so far. And the part­ners have some big plans for the fu­ture.

“Ob­vi­ous­ly there’s a lot of press and clin­i­cal da­ta and ex­cite­ment around CAR-T,” says Rams­dell, the vice pres­i­dent for re­search at the Park­er In­sti­tute. “That’s great and won­der­ful. What Tes­sa is do­ing is a lot dif­fer­ent.”

In­stead of ex­tract­ing T cells and reengi­neer­ing them to hunt down and kill can­cer cells, a CAR-T ap­proach that re­quires ag­gres­sive man­age­ment of some se­vere re­ac­tions but with some re­mark­able re­sults for liq­uid can­cers, Tes­sa takes blood and ex­pands and adapts virus-spe­cif­ic T cells to tar­get vi­ral­ly-as­so­ci­at­ed tu­mors like cer­vi­cal and head and neck can­cer, swarm­ing the cells.

“As much as its tech­no­log­i­cal as­pect, it’s al­so a philo­soph­i­cal align­ment,” Rams­dell adds about the al­liance. “They have a very good sci­en­tif­ic un­der­pin­ning. They know what they’re do­ing; very well round­ed….You nev­er know, but it looks re­al­ly quite good.”

In this new col­lab­o­ra­tion, star im­munother­a­py spe­cial­ists like Phil Green­berg at the Fred Hutch and Crys­tal Mack­all of Stan­ford are be­ing brought in to work with Tes­sa’s re­search team, head­ed by Chief Sci­en­tif­ic Of­fi­cer John Con­nol­ly and CMO Han Chong Toh, the deputy di­rec­tor of the Na­tion­al Can­cer Cen­tre Sin­ga­pore and one of the top can­cer in­ves­ti­ga­tors in the re­gion. Oth­er in­ves­ti­ga­tors in the Park­er net­work can al­so pitch ideas on ad­vanc­ing the work, pos­si­bly even get­ting fund­ing for small proof-of-con­cept stud­ies to test their no­tions.

“In any col­lab­o­ra­tion,” says Rams­dell, “we can be the hub of that wheel and bring the dif­fer­ent ap­proach­es to­geth­er.”

That fits in per­fect­ly with Tes­sa’s strat­e­gy, Con­nol­ly tells me. The vet­er­an Bay­lor Col­lege of Med­i­cine in­ves­ti­ga­tor ran in­to Han Chong Toh — who had been at the Cen­ter for Cell and Gene Ther­a­py at Bay­lor Col­lege of Med­i­cine work­ing un­der found­ing di­rec­tor Mal­colm Bren­ner — af­ter he moved to Sin­ga­pore in 2010 to set up a lab.

John Con­nol­ly

Tes­sa’s Phase III will read out in 2018, says Con­nol­ly, giv­ing them a piv­otal chance to demon­strate how they can trans­form B cells with the Ep­stein-Barr virus, mov­ing be­yond ran­dom ac­ti­va­tion of T cells with chimeric anti­gen re­cep­tors to a po­ten­tial­ly much more tar­get­ed cell ther­a­py de­signed to con­tin­u­al­ly hunt down and kill spe­cif­ic can­cer cells. The HPV pro­gram can do the same for head and neck and oth­er can­cers. And when you start to mar­ry this ap­proach with oth­er im­munother­a­pies, you can start to vi­su­al­ize Tes­sa’s goal: elim­i­nat­ing sol­id tu­mors, the Holy Grail of cell ther­a­py.

Con­nol­ly and Han Chong Toh are di­rect­ing the late-stage pro­gram, sanc­tioned with the FDA’s fast track and or­phan drug des­ig­na­tions, which is be­ing con­duct­ed in 5 coun­tries with 29 sites.

Rams­dell was at­tract­ed by an ap­proach that should avoid off­site tox­i­c­i­ty. And with the nat­ur­al sig­nal­ing in­volved, he al­so be­lieves you’re more like­ly to cre­ate mem­o­ry cells that can keep up the at­tack — promis­ing a durable re­sponse.

“Tes­sa (with a base of IP in-li­censed from Bay­lor Col­lege of Med­i­cine) adds their own se­cret sauce of cy­tokines that ac­ti­vate in a par­tic­u­lar way for good killing and dura­bil­i­ty,” notes Rams­dell, help­ing avoid the risk of burn­ing the cells out, which hap­pens when you mul­ti­ply their num­bers.

The ear­ly re­sults “showed beau­ti­ful sur­vival da­ta,” says Con­nol­ly, which helped at­tract a line­up of fam­i­ly of­fices and high net worth in­vestors to back a biotech that now has a staff of about 130.

Tes­sa turned up at AS­CO in ear­ly June with Phase II da­ta on 35 pa­tients with rare cas­es of Stage 4c na­sopha­ryn­geal car­ci­no­ma, or NPC, as­so­ci­at­ed with Ep­stein-Barr virus. Their con­clu­sion:

The 2- and 3-year over­all sur­vival rates were 62.9% and 37.1% re­spec­tive­ly, which rep­re­sent the best re­port­ed sur­vival out­come for first-line treat­ment of ad­vanced NPC when com­pared to his­tor­i­cal clin­i­cal tri­als.

Tes­sa added that it has bio­mark­ers to iden­ti­fy which pa­tients are like­ly to ben­e­fit, the kind of strat­e­gy that the FDA prefers.

‘We’re very in­ter­est­ed in mov­ing CAR-T to next-gen as well, putting pay­loads in­to CAR-T, etcetera, etcetera,” says Rams­dell. “The par­al­lel here is that as you move in­to sol­id tu­mors, Tes­sa is more ad­vanced tech­ni­cal­ly, con­cep­tu­al­ly and philo­soph­i­cal­ly.”

Just a few months ago Tes­sa launched a col­lab­o­ra­tion with Rochester, MN-based Vyr­i­ad, which has clin­i­cal-stage on­colyt­ic virus­es that in­fect and de­stroy can­cer cells, but al­so use anti­gens to flag an im­mune sys­tem at­tack (one of a group of next-gen on­colyt­ics com­pa­nies look­ing to do T-Vec bet­ter. Tes­sa sees it as a match of syn­er­gis­tic tech­nolo­gies for fight­ing can­cer.

In March Tes­sa al­so bought out an­oth­er Sin­ga­pore start­up, Eu­chloe, which has been work­ing on a slate of an­ti­bod­ies, in­clud­ing PD-1, as well as chimeric anti­gen re­cep­tor tech­nolo­gies for next-gen CARs.

Tes­sa may just be still in the ear­ly stages of its de­but on the glob­al biotech scene. But with Asian biotechs tak­ing a more cen­tral role in drug de­vel­op­ment, it could al­ready be on the verge of do­ing some­thing big.

Trump’s HHS claims ab­solute au­thor­i­ty over the FDA, clear­ing path to a vac­cine EUA

The top career staff at the FDA has vowed not to let politics overrule 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 the FDA and other health agencies under his purview of their rule making 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.

PhII Alzheimer's fail­ure deals new blow to Roche, AC Im­mune — but the tau hy­poth­e­sis is far from dead

The leading anti-tau antibody has failed its first Phase II testing, casting a shadow on a popular target (just trailing amyloid beta) for Alzheimer’s disease.

Roche and AC Immune are quick to acknowledge disappointment in the topline readout, which suggested that semorinemab did not reduce cognitive decline among patients with early Alzheimer’s disease, who are either just starting to have symptoms or have mild manifestations.

Un­der fire, FDA to is­sue stricter guid­ance for Covid-19 vac­cine EUA this week — re­port

The FDA has been insisting for months that a Covid-19 vaccine had to be at least 50% effective – a measure of transparency meant to shore public trust in the agency and in a vaccine that had been brought forward at record speed and record political pressure. But now, with concerns of a Trump-driven authorization arriving before the election, the agency may be raising the bar.

The FDA is set to release new guidance that would raise safety and efficacy requirements for a vaccine EUA above earlier guidance and above the criteria used for convalescent plasma or hydroxychloroquine, The Washington Post reported. Experts say this significantly lowers the odds of an approval before the election on November 3, which Trump has promised despite vocal concerns from public health officials, and could help shore up public trust in the agency and any eventual vaccine.

Covid-19 roundup: J&J be­gins piv­otal Phase III tri­al for vac­cine; Con­tro­ver­sial hu­man chal­lenge tri­als to be­gin in Lon­don — re­port

Johnson & Johnson announced it’s beginning a pivotal Phase III trial for its Covid-19 candidate, JNJ-78436735 — the first single-dose vaccine in this stage.

The Phase III trial, dubbed ENSEMBLE, will enroll 60,000 patients worldwide, making it the largest Phase III study of a Covid-19 vaccine to date. J&J said the candidate achieved positive interim results in a Phase I/IIa study, which will be published “imminently.” There’s a possibility that the first batches will be ready for potential emergency use in early 2021, according to the biotech.

UP­DAT­ED: Still held down by clin­i­cal hold, No­var­tis' Zol­gens­ma falls fur­ther be­hind Bio­gen and Roche as FDA asks for a new piv­otal study

Last October, the FDA slowed down Novartis’ quest to extend its gene therapy to older spinal muscular atrophy patients by slapping a partial hold on intrathecal administration. Almost a year later, the hold is still there, and regulators are adding another hurdle required for regulatory submission: a new pivotal confirmatory study.

The new requirement — which departs significantly from Novartis’ prior expectations — will likely stretch the path to registration beyond 2021, when analysts were expecting a BLA submission. That could mean more time for Biogen to reap Spinraza revenues and Roche to ramp up sales of Evrysdi in the absence of a rival.

As its biotechs hit the pan­dem­ic ex­it, Lon­gi­tude rais­es $585M for new neu­ro, can­cer, ag­ing and or­phan-fo­cused fund

The years have been kind to Longitude Capital. This year, too.

A 2006 spinout of Pequot Capital, its founders started their new firm just four years before the parent company would go under amid insider trading allegations. Their first life sciences fund raised $325 million amid the financial crisis, they added a second for $385 million and then in, 2016, a third for $525 million. In the last few months, the pandemic biotech IPO boom netted several high-value exits from those funds, as Checkmate, Vaxcyte, Inozyme and Poseida all went public.

Scoop: ARCH’s Bob Nelsen is back­ing an mR­NA up­start that promis­es to up­end the en­tire man­u­fac­tur­ing side of the glob­al busi­ness

For the past 2 years, serial entrepreneur Igor Khandros relied on a small network of friends and close insiders to supply the first millions he needed to fund a secretive project to master a new approach to manufacturing mRNA therapies.

Right now, he says, he has a working “GMP-in-a-box” prototype for a new company he’s building — after launching 3 public companies — which plans to spread this contained, precise manufacturing tech around the world with a set of partners. He’s raised $60 million, recruited some prominent experts. And not coincidentally, he’s going semi-public with this just as a small group of pioneers appears to be on the threshold of ushering in the world’s first mRNA vaccines to fight a worldwide pandemic.

Samit Hirawat (Bristol Myers Squibb)

Af­ter bruis­ing re­jec­tion, blue­bird and Bris­tol My­ers Squibb land ide-cel pri­or­i­ty re­view. But will it mat­ter for the CVR?

With the clock all but up, the FDA accepted and handed priority review to Bristol Myers Squibb and bluebird bio’s BCMA CAR-T, keeping a narrow window open for Celgene investors to still cash in on the $9 CVR from the $63 billion Celgene merger.

The acceptance comes five months after the two companies weres slammed with a surprise refuse-to-file that threatened to foreclose the CVR entirely. Today’s acceptance sets the FDA decision date for March 27, 2021 – or precisely 4 days before the CVR deadline of March 31. Given the breakthrough designation and strong pivotal data — 81.5% response rate, 35.2% complete response rate — priority review was largely expected.
