While gene ther­a­py com­pa­nies re­joice as the sec­tor gains trac­tion with ap­provals and a flur­ry of M&A ac­tiv­i­ty, one play­er is feel­ing the heat.

Back in 2015, Voy­ager Ther­a­peu­tics joined forces with Sanofi Gen­zyme in a deal worth up to $845 mil­lion ($100 mil­lion up­front + a po­ten­tial $745 mil­lion in mile­stones) to co-de­vel­op gene ther­a­pies for se­vere cen­tral ner­vous sys­tem dis­or­ders. But two years lat­er, the French drug­mak­er re­treat­ed, elect­ing to not pick up the op­tion to work on Voy­ager’s Parkin­son’s dis­ease pro­gram. (Last year, the FDA dis­ap­point­ed Voy­ager, telling the com­pa­ny that it was not open to an ac­cel­er­at­ed fil­ing on the Parkin­son’s drug on the ba­sis of Phase II da­ta — in­stead re­quir­ing an ad­di­tion­al piv­otal study.)

Sanofi Gen­zyme’s re­treat now re­sem­bles a de­ser­tion.

On Mon­day, Voy­ager $VY­GR said Sanofi Gen­zyme is walk­ing away from op­tions to ac­quire US co-com­mer­cial­iza­tion rights and ex-US de­vel­op­ment and com­mer­cial­iza­tion rights to ex­per­i­men­tal Hunt­ing­ton’s dis­ease drug VY-HTT01 and to Friedre­ich’s atax­ia pro­gram VY-FXN01; and a fu­ture Voy­ager CNS or­phan pro­gram. In ad­di­tion, Voy­ager and Sanofi Gen­zyme’s al­liance on SMA has al­so been ter­mi­nat­ed —  the in­tel­lec­tu­al prop­er­ty rights of the pro­gram are be­ing re­turned/ex­clu­sive­ly li­censed to Sanofi Gen­zyme.

Con­se­quent­ly, Voy­ager has agreed to give $10 mil­lion up­front to Sanofi Gen­zyme, and an ad­di­tion­al $10 mil­lion mile­stone pay­ment up­on the po­ten­tial fil­ing of an ap­pli­ca­tion to test in hu­mans the Hunt­ing­ton’s dis­ease drug, VY-HTT01 or, cer­tain back­up com­pounds, as well as po­ten­tial roy­al­ties. In ad­di­tion, Voy­ager is al­so of­fer­ing Sanofi Gen­zyme ex­clu­sive dibs to se­lect AAV cap­sids from its ar­se­nal of drugs in de­vel­op­ment in up to two non-CNS in­di­ca­tions.

Re­cent­ly, Voy­ager has been busy shop­ping for oth­er part­ners. It has inked deals with Ab­b­Vie and Neu­ro­crine this year.

On Mon­day, Voy­ager trans­ferred the ex-US rights to the Sanofi-aban­doned Friedre­ich’s atax­ia pro­gram to Neu­ro­crine. The com­pa­ny al­so sig­naled that it plans to part­ner out its ALS gene ther­a­py, VY-SOD102, (and no longer plans to file an IND for it this year), to fo­cus its re­sources on Hunt­ing­ton’s.

“While it is un­clear ex­act­ly who might be look­ing to in-li­cense this pro­gram, Bio­gen might serve as an in­ter­est­ing can­di­date giv­en their ex­ist­ing work on SOD1 with their an­ti­sense oligonu­cleotide (ASO), tofersen, and close prox­im­i­ty giv­en both com­pa­nies are based in Cam­bridge. How­ev­er, if Bio­gen were to do this deal it might al­so be an ear­ly sig­nal to in­vestors that they view gene ther­a­py as strong al­ter­na­tive to their ASO port­fo­lio, po­ten­tial­ly ac­cept­ing that Zol­gens­ma is go­ing to be a strong com­peti­tor in SMA,” Baird’s Bri­an Sko­r­ney wrote in a note.

So­cial im­age: Shut­ter­stock

Gilead is surging again off data that suggest its antiviral remdesivir might improve survival.

The new data come from an analysis Gilead conducted comparing the death rate and recovery time of patients in one of its remdesivir trials to a group of 800 patients “with similar baseline characteristics and disease severity” who received only standard-of-care around the same time. The result, they said, suggested that patients who received remdesivir had a 62% better chance at surviving than those who did not.

Frank Nestle was appointed Sanofi’s global head of immunology and inflammation research therapeutic area just days before dupilumab, the blockbuster-to-be IL-4 antibody, would be accepted for priority review. After four years of consolidating immunology expertise from multiple corners of the Sanofi family and recruiting new talents to build the discovery engine, he’s set eyes on a Phase I-ready program that he believes can grow into a Dupixent-sized franchise.

Four more biotechs are raising their offers in an already record year for biotech IPOs.

Softbank-backed Relay Therapeutics scratched out its original $200 million filing and proposed a $250 million raise that would make them a $1.5 billion company. CAR-T developer Poseida Therapeutics bumped itself up $74 million to $224 million. Off-the-shelf cell therapy startup Nkarta upped from $150 million to $215 million — and then priced even higher, at $252 million. France’s Inventiva did its own modest reset, raising its bar from $102 million to $108 million.

Many in the pharma world are hoping — better yet, expecting — JAK inhibitors to provide one of the next big boons for the industry. Few have invested as heavily in this area as Pfizer, which boasts a portfolio including Xeljanz and at least five mid-to-late stage candidates in the pipeline.

But a top Wall Street analyst is pumping the brakes on just how much good fortune is in store for the Big Pharma.
