Next-gen T cell play­er TCR2 Ther­a­peu­tics sets stage for $100M-plus IPO as MP­M's Baeuer­le caps pro­lif­ic year

Patrick Baeuer­le

Patrick Baeuer­le has been busy. Right af­ter steer­ing next-gen BiTE com­pa­ny Har­poon Ther­a­peu­tics to­ward an IPO, the MPM part­ner and im­mu­nol­o­gist is shep­herd­ing an­oth­er on­col­o­gy com­pa­ny with pre­clin­i­cal as­sets — TCR2 Ther­a­peu­tics — in­to a pub­lic list­ing. And this time the biotech is look­ing for $100 mil­lion-plus in a mar­ket that’s been on a wild roller coast­er ride.

The im­munother­a­py com­pa­ny is de­vel­op­ing next-gen T-cell drugs for can­cer in an ef­fort to con­front lim­i­ta­tions posed by cur­rent T-cell and CAR-T ther­a­pies in sol­id tu­mors.

Robert Hofmeis­ter

One of the key com­po­nents of the im­mune sys­tem are T cells, which oblit­er­ate can­cer cells by us­ing T cell re­cep­tor (TCR) recog­ni­tion of cell sur­face mark­ers known as anti­gens. When a T cell rec­og­nizes a tu­mor anti­gen via the TCR, it snuffs the ma­lig­nant cell on which it re­sides. Ex­ist­ing T cell ther­a­pies for can­cer, in­clud­ing CAR-T cells and en­gi­neered TCR-T cells, at­tempt to repli­cate this mech­a­nism.

The drug de­vel­op­er’s tech­nol­o­gy — called TRuC-T cells — is de­signed to rec­og­nize and kill can­cer cells by har­ness­ing the TCR sig­nal­ing com­plex, un­like CAR-T for in­stance, which on­ly taps in­to a part of the TCR struc­ture. In con­trast to ex­ist­ing T cell ther­a­pies, the TCR2 tech­nol­o­gy is fash­ioned such that it could be used across pa­tients that ex­press the can­cer sur­face anti­gen ir­re­spec­tive of hu­man leuko­cyte anti­gens (HLA) sub­type, which could po­ten­tial­ly ad­dress a larg­er group of pa­tients.

The com­pa­ny has 5 drugs in its ar­se­nal. Its lead can­di­date — TC-210 — is be­ing de­vel­oped to tar­get mesothe­lin-pos­i­tive sol­id tu­mors. An ap­pli­ca­tion to test the drug in hu­mans was sub­mit­ted in De­cem­ber and the com­pa­ny ex­pects to con­duct a Phase I/II study ear­ly in 2019, and even­tu­al­ly ap­ply for the FDA’s fast track sta­tus. Its sec­ond drug, TC-110, is be­ing eval­u­at­ed for CD19-pos­i­tive B-cell hema­to­log­i­cal ma­lig­nan­cies. An IND is ex­pect­ed to be filed in the sec­ond half of 2019 and the com­pa­ny will al­so seek a fast track des­ig­na­tion for this as­set.  The rest — TC-220, TC-310 and TC-410 — are in ear­li­er stages of pre­clin­i­cal de­vel­op­ment.

Al­fon­so Quin­tás Car­dama

TCRwill have two ex­pe­ri­enced sci­en­tif­ic minds work­ing on their pipeline in the clin­ic: Robert Hofmeis­ter, who de­vel­oped one of the first PD-L1 in­hibitors — Baven­cio — while at EMD Serono, will serve as CSO, while Al­fon­so Quin­tás Car­dama, who was piv­otal in the ap­proval process for one of the two li­censed T cell ther­a­pies for hema­to­log­i­cal ma­lig­nan­cies — No­var­tis’ Kym­ri­ah — will serve as CMO.

The com­pa­ny will be list­ed on the Nas­daq un­der the sym­bol $TCRR, ac­cord­ing to the S-1 post­ed last week. TCRwas found­ed by Baeuer­le, a part­ner at MPM who pre­vi­ous­ly served as CSO at Mi­cromet be­fore it was swal­lowed by Am­gen. Baeuer­le was ush­ered in­to Am­gen — where R&D was then run by Roger Perl­mut­ter — fol­low­ing the buy­out, to help take Mi­cromet’s Blin­cy­to across the fin­ish line.

Mitchell Fin­er

TCR2 al­so worked close­ly with Mitchell Fin­er, an MPM Cap­i­tal ex­ec­u­tive part­ner who has decades of cell ther­a­py man­u­fac­tur­ing ex­pe­ri­ence, in­clud­ing the de­sign of GMP process­es for blue­bird bio and Cell Genesys. Over­all, just un­der half of the 30 com­pa­nies MPM has in­vest­ed in are on­col­o­gy-fo­cused.

So far, TCR2  has raised rough­ly $170 mil­lion from in­vestors, in­clud­ing MPM Cap­i­tal, F2 Ven­tures, Di­men­sions Cap­i­tal, Ar­row­Mark Part­ners, Cathay For­tune Cap­i­tal, Cu­ra­tive Ven­tures, Hill­house Cap­i­tal Group, Mi­rae­As­set Fi­nan­cial Group and Red­mile Group. Pri­or to the IPO, MPM has the biggest hold­ing with a 19.18% stake, and F2 is a run­ner up with a 15.97% stake.

As Nas­daq en­rolls the fi­nal batch of 2019 IPOs, how have the num­bers com­pared to past years?

IGM Biosciences’ upsized IPO haul, coming after SpringWorks’ sizable public debut, has revved up some momentum for the last rush of biotech IPOs in 2019.

With 39 new listings on the books and roughly two more months to go before winding down, Nasdaq’s head of healthcare listings Jordan Saxe sees the exchange marking 50 to 60 biopharma IPOs for the year.

“December 15 is usually the last possible day that companies will price,” he said, as companies get ready for business talks at the annual JP Morgan Healthcare Conference in January.

'Dis­con­nect the bas­tard­s' — one biotech's plan to break can­cer cell­s' uni­fied de­fens­es

Chemotherapy and radiotherapy are the current gladiators of cancer treatment, but they come with well-known limitations and side-effects. The emergence of immunotherapy — a ferocious new titan in oncologist’s toolbox — takes the brakes off the immune system to kill cancer cells with remarkable success in some cases, but the approach is not always effective. What makes certain forms of cancer so resilient? Scientists may have finally pieced together a tantalizing piece of the puzzle, and a new biotech is banking on a new approach to fill the gap.

While No­var­tis ban­ish­es Zol­gens­ma scan­dal scars — Bio­gen goes on a Spin­raza 'of­fen­sive'

While Novartis painstakingly works to mop up the stench of the data manipulation scandal associated with its expensive gene therapy for spinal muscular atrophy (SMA) Zolgensma— rival Biogen is attempting to expand the use of its SMA therapy, Spinraza. 

The US drugmaker $BIIB secured US approval for Spinraza for use in the often fatal genetic disease in 2016. The approval covered a broad range of patients with infantile-onset (most likely to develop Type 1) SMA.

UP­DAT­ED: Speak­er Nan­cy Pelosi to un­veil bill for fed­er­al­ly ne­go­ti­at­ed drug prices

After months of buzz from both sides of the aisle, Speaker Nancy Pelosi will today introduce her plan to allow the federal government to negotiate prices for 250 prescription drugs, setting up a showdown with a pharmaceutical industry working overtime to prevent it.

The need to limit drug prices is a rare point of agreement between President Trump and Democrats, although the president has yet to comment on the proposal and will likely face pressure to back a more conservative option or no bill at all. Republican Senator Chuck Grassley is reportedly lobbying his fellow party members on a more modest proposal he negotiated with Democratic Senator Ron Wyden in July.

Jeff Kindler's Cen­trex­ion re­news bid to make pub­lic de­but

Jeffrey Kindler’s plan to take his biotech — which is developing a slate of non-opioid painkillers — public, is back on.

The Boston based company, led by former Pfizer $PFE chief Kindler, originally contemplated a $70 million to $80 million IPO last year— but eventually postponed that strategy. On Wednesday, the company revived its bid to make a public debut in a filing with the SEC — although no pricing details were disclosed.

'A fourth rev­o­lu­tion in can­cer ther­a­pies': ARCH-backed Bound­less Bio flash­es big check, makes big­ger promis­es in de­but

It was the cellular equivalent of opening your car door and finding an active, roaring engine in the driver seat.

Scientists learned strands of DNA could occasionally appear outside of its traditional home in the nucleus in the 1970s, when they appeared as little, innocuous circles on microscopes; inexplicable but apparently innate. But not until UC San Diego’s Paul Mischel published his first study in Science in 2014 did researchers realize these circles were not only active but potentially overactive and driving some cancer tumors’ superhuman growth.

Scott Got­tlieb is once again join­ing a team that en­joyed good times at the FDA un­der his high-en­er­gy stint at the helm

Right after jumping on Michael Milken’s FasterCures board on Monday, the newly departed FDA commissioner is back today with news about another life sciences board post that gives him a ringside chair to cheer on a lead player in the real-world evidence movement — one with very close ties to the FDA.

Aetion is reporting this morning that Gottlieb is joining their board, a group that includes Mohamad Makhzoumi, a general partner at New Enterprise Associates, where Gottlieb returned after stepping out of his role at the FDA 2 years after he started.

Gottlieb — one of the best connected execs in biopharma — knows this company well. As head of FDA he championed the use of real-world evidence to help guide drug developers and the agency in gaining greater efficiencies, which helped set up Aetion as a high-profile player in the game.
