Months af­ter IPO, No­var­tis spin­out resTOR­bio wins on PhI­Ib da­ta — stock soars

Just six months af­ter its de­but on the Nas­daq, resTOR­bio is trot­ting out late-stage da­ta this morn­ing for its lead drug can­di­date — a TORC1 in­hibitor they’re hop­ing will pre­vent res­pi­ra­to­ry in­fec­tions in el­der­ly folks. While it flopped in a com­bo tri­al, the com­pa­ny’s drug met its pri­ma­ry end­point when test­ed by it­self.

In­vestors are thrilled with the news, with resTOR­bio’s share price $TORC fly­ing up 161% as of press time. Yes­ter­day’s close was at $9.01 per share, and to­day its so far climbed to $23.50. If it holds, that’s a de­cent jump from its IPO price of $14 to $16 per share.

Joan Man­nick

The drug — spun out of No­var­tis in­to its own start­up just last year — is now called RTB101, al­though it once went un­der the code name BEZ235. In a Phase IIb tri­al, the 10 mg dose of the drug showed a sta­tis­ti­cal­ly sig­nif­i­cant re­duc­tion in res­pi­ra­to­ry in­fec­tions when tak­en by pa­tients once a day. That co­hort saw a 30.6% de­crease in the per­cent­age of pa­tients who de­vel­oped a res­pi­ra­to­ry in­fec­tion when com­pared to the place­bo co­hort: p=0.026.

In­ter­est­ing­ly, the drug flopped big time when test­ed in com­bi­na­tion with an al­ready-ap­proved im­muno­sup­pres­sant called everolimus, an mTOR in­hibitor of­ten used to pre­vent the re­jec­tion of or­gan trans­plants. When resTOR­bio test­ed RTB101 com­bi­na­tion with everolimus, they found no de­crease in the per­cent­age of pa­tients with res­pi­ra­to­ry in­fec­tions. The drug al­so saw lousy re­sults when the 10 mg dose was tak­en twice dai­ly in­stead of once.

“We’re find­ing that less TORC1 in­hi­bi­tion works bet­ter than more TORC1 in­hi­bi­tion,” the com­pa­ny’s co-founder and CMO Joan Man­nick tells me. They saw a sim­i­lar re­sponse in their Phase IIa tri­al, she said.

Chen Schor

The com­pa­ny’s CEO Chen Schor said he wasn’t too con­cerned that the com­bo and dou­ble dos­es didn’t per­form well. In fact, the drug work­ing as a monother­a­py is ben­e­fi­cial.

“We pre­fer to move for­ward with the monother­a­py, be­cause it’s eas­i­er to man­u­fac­ture,” he said. “That was our hope.”

The com­pa­ny al­so homed in on a few spe­cif­ic pa­tient groups in which they saw more promis­ing re­sults. For ex­am­ple, in asth­ma pa­tients, they saw a 68% re­duc­tion in res­pi­ra­to­ry in­fec­tions (p=0.0002), and in pa­tients 85 years or old­er they saw 67% (p=0.007). The tri­al in­volved some 650 pa­tients, ac­cord­ing to clin­i­cal­tri­als.gov, but when resTOR­bio whit­tles down the pa­tient group to these se­lect pop­u­la­tions, we’re talk­ing much few­er peo­ple. I asked Man­nick just how many we’re talk­ing here. In asth­ma, it was on­ly 47 pa­tients, she said, and a mere 27 peo­ple were 85 years old and old­er.

But Man­nick de­fend­ed the da­ta’s sig­nif­i­cance re­gard­less of the small­er pa­tient group. “When you have few­er pa­tients, it’s much hard­er to reach sta­tis­ti­cal sig­nif­i­cance,” she said. “You have to have a big ef­fect.”

The com­pa­ny is meet­ing with the FDA at the end of this year to dis­cuss how it should move for­ward with a Phase III tri­al. Man­nick and Schor said the com­pa­ny will be shoot­ing for a sim­i­lar tri­al de­sign, in which they test co­horts of nar­row pa­tient groups with­in the same tri­al.

Biotech Half­time Re­port: Af­ter a bumpy year, is biotech ready to re­bound?

The biotech sector has come down firmly from the highs of February as negative sentiment takes hold. The sector had a major boost of optimism from the success of the COVID-19 vaccines, making investors keenly aware of the potential of biopharma R&D engines. But from early this year, clinical trial, regulatory and access setbacks have reminded investors of the sector’s inherent risks.

RBC Capital Markets recently surveyed investors to take the temperature of the market, a mix of specialists/generalists and long-only/ long-short investment strategies. Heading into the second half of the year, investors mostly see the sector as undervalued (49%), a large change from the first half of the year when only 20% rated it as undervalued. Around 41% of investors now believe that biotech will underperform the S&P500 in the second half of 2021. Despite that view, 54% plan to maintain their position in the market and 41% still plan to increase their holdings.

No­var­tis de­vel­op­ment chief John Tsai: 'We go deep in the new plat­form­s'

During our recent European Biopharma Summit, I talked with Novartis development chief John Tsai about his experiences over the 3-plus years he’s been at the pharma giant. You can read the transcript below or listen to the exchange in the link above.

John Carroll: I followed your career for quite some time. You’ve had more than 20 years in big pharma R&D and you’ve obviously seen quite a lot. I really was curious about what it was like for you three and a half years ago when you took over as R&D chief at Novartis. Obviously a big move, a lot of changes. You went to work for the former R&D chief of Novartis, Vas Narasimhan, who had his own track record there. So what was the biggest adjustment when you went into this position?

As­traZeneca on­col­o­gy R&D chief Su­san Gal­braith: 'Y­ou're go­ing to need or­thog­o­nal com­bi­na­tion­s'

 

Earlier in the week we broadcast our 4th annual European Biopharma Summit with a great lineup of top execs. One of the one-on-one conversations I set up was with Susan Galbraith, the oncology research chief at AstraZeneca. In a wide-ranging discussion, Galbraith reviewed the cancer drug pipeline and key trends influencing development work at the pharma giant.

A star Stan­ford pro­fes­sor leaves his lab for a start­up out to re­make psy­chi­a­try

About five years ago, Amit Etkin had a breakthrough.

The Stanford neurologist, a soft-spoken demi-prodigy who became a professor while still a resident, had been obsessed for a decade with how to better define psychiatric disorders. Drugs for depression or bipolar disorder didn’t work for many patients with the conditions, and he suspected the reason was how traditional diagnoses didn’t actually get at the heart of what was going on in a patient’s brain.

Roche's Tecen­triq cross­es the fin­ish line first in ad­ju­vant lung can­cer, po­ten­tial­ly kick­ing off gold rush

While falling behind the biggest PD-(L)1 drugs in terms of sales, Roche has looked to carve out a space for its Tecentriq with a growing expertise in lung cancer. The drug will now take an early lead in the sought-after adjuvant setting — but competitors are on the way.

The FDA on Friday approved Tecentriq as an adjuvant therapy for patients with Stage II-IIIA non small cell lung cancer with PD-(L)1 scores greater than or equal to 1, making it the first drug of its kind approved in an early setting that covers around 40% of all NSCLC patients.

Imfinzi/treme­li­mum­ab com­bo scores As­traZeneca an­oth­er OS win — this time in liv­er can­cer

Is the tide turning on AstraZeneca’s battered PD-L1/CTLA4 combo?

A single priming dose of the experimental tremelimumab, followed by Imfinzi every four weeks, beat Nexavar (sorafenib) in helping a group of liver cancer patients live longer in a Phase III study, the company reported, meeting the primary endpoint.

Specifically, the two drugs extended overall survival for patients with unresectable hepatocellular carcinoma who had not received prior systemic therapy and were not eligible for localized treatment.

FDA+ roundup: Marks on Wood­cock­'s tenure as act­ing com­mis­sion­er; FDA lead­ers of­fer per­spec­tive on bar­ri­ers to di­ver­si­ty in re­search

CBER director Peter Marks praised Janet Woodcock’s work as acting FDA commissioner, and while noting that Biden needs to nominate someone to fill the role permanently by Nov. 16, he said he has “no idea” when that actually might occur.

“Dr. Woodcock has been at the agency for over three decades and she, during that time, has proven herself to be a remarkably capable manager,” Marks said at the Alliance for Regenerative Medicine’s meeting Tuesday. “And she’s been managing as if she’s commissioner, unlike some previous acting [commissioners] who are afraid to actually do things. She doesn’t appear to be afraid to do things. I have not felt any different now from when we had a commissioner in place,” he added.

FDA ad­comm votes unan­i­mous­ly in sup­port of a J&J Covid-19 boost­er two months af­ter one-dose shot

The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) on Friday voted 19-0 in favor of authorizing a second shot of J&J’s Covid-19 vaccine to follow at least two months after the initial dose.

Regulators don’t have to follow VRBPAC’s recommendation, but they almost always do. Considering that the CDC’s advisory committee has already been set to review the expanded EUA, VRBPAC’s recommendation is likely to be adopted.
