Tossed in a storm of con­tro­ver­sies, Pro­teosta­sis finds shel­ter in $100M cash Roche deal — shares surge

Af­ter a tu­mul­tuous year marked by a vi­cious short at­tack, a yanked stock of­fer­ing and en­cour­ag­ing ear­ly da­ta on its cys­tic fi­bro­sis (CF) dou­blet, tiny biotech Pro­teosta­sis Ther­a­peu­tics has won the en­dorse­ment of mighty Roche, which has seized the rights to po­ten­tial small mol­e­cule mod­u­la­tors with undis­closed tar­gets from the em­bat­tled com­pa­ny.

Un­der the deal — which does not in­clude the con­tro­ver­sial com­pa­ny’s CFTR mod­u­la­tors and its drugs-in-de­vel­op­ment or re­search pro­grams in CF — Pro­teosta­sis is el­i­gi­ble to re­ceive up­front and mile­stone pay­ments of over $100 mil­lion. The Swiss drug­mak­er $RHB­BY is now in charge of all R&D ex­pens­es for the pro­gram, and if any ap­proved prod­ucts emerge from the deal, Pro­teosta­sis will make tiered roy­al­ties on sales. 

The an­nounce­ment on Mon­day lift­ed the small drug de­vel­op­er’s $PTI shares up near­ly 20% be­fore the bell.

The mod­u­la­tors come from the Cam­bridge, MA-based com­pa­ny’s plat­form that con­trols and re­bal­ances the pro­teosta­sis net­work (PN). The PN en­sures pro­teins reach their fi­nal des­ti­na­tion cor­rect­ly fold­ed with ap­pro­pri­ate func­tion or be de­grad­ed and cleared to pre­vent dam­age. But when the pro­teome is im­bal­anced — due to a pletho­ra of fac­tors such as ge­net­ic mu­ta­tions and en­vi­ron­men­tal in­flu­ences — that cul­mi­nates in poor pro­tein qual­i­ty and even­tu­al­ly, dis­ease. Pro­teosta­sis’ tech­nol­o­gy helps these pro­teins reach fi­nal des­ti­na­tions in path­ways while cor­rect­ly fold­ed.

The agree­ment val­i­dates the com­pa­ny’s PN po­ten­tial, Can­tor Fitzger­ald’s El­e­mer Piros wrote in a note, not­ing that Pro­teosta­sis has al­ready demon­strat­ed ear­ly proof-of-con­cept for the tech­nol­o­gy in CF.

Giv­en the num­ber of in­di­ca­tions that are caused by loss-of-func­tion, lead­ing to in­ef­fi­cient fold­ing/ex­ces­sive degra­da­tion, we be­lieve this col­lab­o­ra­tion could open the door for fu­ture li­cens­ing agree­ments.

In Oc­to­ber, the small biotech sky­rock­et­ed 448% on ini­tial pos­i­tive da­ta on a hand­ful of CF pa­tients who were giv­en a com­bi­na­tion of its two ex­per­i­men­tal drugs — PTI-808 and PTI-801 — im­press­ing an­a­lysts who drew com­par­isons with CF ma­jor Ver­tex’s $VRTX Orkam­bi and Symdeko, and shored up their ex­pec­ta­tions for a triplet cock­tail. But the pre­ced­ing months were not as kind. In June, the stock was ham­mered on lack­lus­ter da­ta on PTI-801 as a monother­a­py — a set­back that came months af­ter Pro­teosta­sis re­scind­ed a planned of­fer­ing of 9 mil­lion shares in re­sponse to a a scathing re­view of its CFTR am­pli­fi­er PTI-428 from short sell­er Ker­ris­dale Cap­i­tal.

Pre­lim­i­nary da­ta on the com­pa­ny’s triplet com­bo are ex­pect­ed by the end of the year.

UP­DAT­ED: AveX­is sci­en­tif­ic founder was axed — and No­var­tis names a new CSO in wake of an ethics scan­dal

Now at the center of a storm of controversy over its decision to keep its knowledge of manipulated data hidden from regulators during an FDA review, Novartis CEO Vas Narasimhan has found a longtime veteran in the ranks to head the scientific work underway at AveXis, where the incident occurred. And the scientific founder has hit the exit.

Ab­b­Vie gets its FDA OK for JAK in­hibitor upadac­i­tinib, but don’t look for this one to hit ex­ecs’ lofty ex­pec­ta­tions

Another big drug approval came through on Friday afternoon as the FDA OK’d AbbVie’s upadacitinib — an oral JAK1 inhibitor that is hitting the rheumatoid arthritis market with a black box warning of serious malignancies, infections and thrombosis reflecting fears associated with the class.

It will be sold as Rinvoq — at a wholesale price of $59,000 a year — and will likely soon face competition from a drug that AbbVie once controlled, and spurned. Reuters reports that a 4-week supply of Humira, by comparison, is $5,174, adding up to about $67,000 a year.

The top 10 fran­chise drugs in bio­phar­ma his­to­ry will earn a to­tal of $1.4T (tril­lion) by 2024 — what does that tell us?

Just in case you were looking for more evidence of just how important Amgen’s patent win on Enbrel is for the company and its investors, EvaluatePharma has come up with a forward-looking consensus estimate on what the list of top 10 drugs will look like in 2024.

ICER blasts FDA, PTC and Sarep­ta for high prices on DMD drugs Em­flaza, Ex­ondys 51

ICER has some strong words for PTC, Sarepta and the FDA as the US drug price watchdog concludes that as currently priced, their respective new treatments for Duchenne muscular dystrophy are decidedly not cost-effective.

The final report — which cements the conclusions of a draft issued in May — incorporates the opinion of a panel of 17 experts ICER convened in a public meeting last month. It also based its analysis of Emflaza (deflazacort) and Exondys 51 (eteplirsen) on updated annual costs of $81,400 and over $1 million, respectively, after citing “incorrect” lower numbers in the initial calculations.

The key dates for KRAS watch­ers through the end of the year — the trail is nar­row and risks are ex­treme

There’s nothing quite like a big patent win when it comes to burnishing your prospects in the pipeline. And for Amgen, which seems to have rescued Enbrel for a run to 2029, the cheering section on Wall Street is now fixed on AMG 510 and a key rival.

And it didn’t take much data to do it. 

There was the first snapshot of a handful of patients, with a 50% response rate. Then came word that Amgen researchers are also tracking responses in different cancers, at least one in colorectal cancer and appendiceal too. 

Bain's Or­ly Mis­han joins Pfiz­er's neu­ro spin­out Cerev­el; On­colyt­ic virus biotech taps Sil­la­Jen ex­ec He­le­na Chaye as CEO

→ Bain Capital is deploying one of its top investors to Cerevel Therapeutics, steering a $350 million-plus neuro play carved out of Pfizer. Orly Mishan — a co-founder and principal of Bain’s life sciences unit — was involved in the partnership that birthed the biotech spinout in the first place. As Cerevel’s first chief business officer, she is tasked with corporate development, program management as well as technical operations. 

UP­DAT­ED: Sci­en­tist-CEO ac­cused of im­prop­er­ly us­ing con­fi­den­tial in­fo from uni­corn Alec­tor

The executive team at Alector $ALEC has a bone to pick with scientific co-founder Asa Abeliovich. Their latest quarterly rundown has this brief note buried inside:

On June 18, 2019, we initiated a confidential arbitration proceeding against Dr. Asa Abeliovich, our former consulting co-founder, related to alleged breaches of his consulting agreement and the improper use of our confidential information that he learned during the course of rendering services to us as our consulting Chief Scientific Officer/Chief Innovation Officer. We are in the early stage of this arbitration proceeding and are unable to assess or provide any assurances regarding its possible outcome.

There’s no explicit word in the filing on what kind of confidential info was involved, but the proceeding got started 2 days ahead of Abeliovich’s IPO.

Abeliovich, formerly a tenured associate professor at Columbia, is a top scientist in the field of neurodegeneration, which is where Alector is targeted. More recently, he’s also helped start up Prevail Therapeutics as the CEO, which raised $125 million in an IPO. And there he’s planning on working on new gene therapies that target genetically defined subpopulations of Parkinson’s disease. Followup programs target Gaucher disease, frontotemporal dementia and synucleinopathies.

But this time Abeliovich is the CEO rather than a founding scientist. And some of their pipeline overlaps with Alector’s.

Abeliovich and Prevail, though, aren’t taking this one lying down.

Chi­na has be­come a CEO-lev­el pri­or­i­ty for multi­na­tion­al phar­ma­ceu­ti­cal com­pa­nies: the trend and the im­pli­ca­tions

After a “hot” period of rapid growth between 2009 and 2012, and a relatively “cooler” period of slower growth from 2013 to 2015, China has once again become a top-of-mind priority for the CEOs of most large, multinational pharmaceutical companies.

At the International Pharma Forum, hosted in March in Beijing by the R&D Based Pharmaceutical Association Committee (RDPAC) and the Pharmaceutical Research and Manufacturers of America (PhRMA), no fewer than seven CEOs of major multinational pharmaceutical firms participated, including GSK, Eli Lilly, LEO Pharma, Merck KGaA, Pfizer, Sanofi and UCB. A few days earlier, the CEOs of several other large multinationals attended the China Development Forum, an annual business forum hosted by the research arm of China’s State Council. It’s hard to imagine any other country, except the US, having such drawing power at CEO level.
