Ad­vax­is has tak­en its in­vestors on a bit of a roller coast­er ride this year.

The FDA slapped a clin­i­cal hold on a com­bo study of its lead drug ax­al­imo­gene filolis­bac and As­traZeneca’s Imfinzi in wake of a pa­tient death, which re­solved months lat­er af­ter a C-suite over­haul. Late Wednes­day, the New Jer­sey biotech added to the dra­ma by qui­et­ly dis­clos­ing that Am­gen has dropped their $540 mil­lion im­munother­a­py pact.

First inked in 2016 with $65 mil­lion up­front, the deal cen­tered around ADXS-NEO, which is de­signed to re­cruit a T cell at­tack on can­cer us­ing bio­engi­neered bac­te­ria. But Am­gen is re­turn­ing world­wide rights for de­vel­op­ment and com­mer­cial­iza­tion just as Ad­vax­is is en­rolling pa­tients for its proof-of-con­cept work — the last step be­fore Am­gen was sup­posed to take over.

The news sent shares $ADXS in­to a steep drop, plung­ing 28% in pre-mar­ket trad­ing.

With­out giv­ing any rea­sons for the ter­mi­na­tion, Ad­vax­is says it will now eval­u­ate whether to re-part­ner the ADXS-NEO pro­gram. Nei­ther com­pa­nies have re­spond­ed to my re­quests for com­ment.

Am­gen $AMGN will have un­til Feb­ru­ary 8, 2019 to tie up any loose ends.

In 2017 and 2018 Ad­vax­is has re­ceived $5.8 mil­lion and $7.5 mil­lion in re­im­burse­ments re­spec­tive­ly for an al­liance that once promised $475 mil­lion in mile­stones.

The biotech is al­so part­nered with Bris­tol-My­ers on an Op­di­vo com­bi­na­tion pro­gram for ax­al­imo­gene filolis­bac.

The generics producer Glenmark Pharmaceuticals has been handed a warning letter by US regulators.

The letter, which was sent to the manufacturer on Nov. 22, noted issues from an inspection over the summer at Glenmark’s facility in the town of Colvale, India, in the state of Goa.

According to the letter, the FDA found that Glenmark’s investigation of rejected batches of drugs “failed to extend to other batches, dosage strengths, and drug products.” The warning letter also noted that the site had failed to establish “adequate written procedures” for production and process control to ensure drugs have the correct strength, quality and purity.

Two Sumitovant Biopharma entities are merging under one name, effective immediately.

Enzyvant Therapeutics and Altavant Sciences announced they have merged to form a singular entity focused on developing therapies for patients with rare diseases. The combined company will keep the name Enzyvant and along with clinical development will eventually include in-house manufacturing.

Bill Symonds, the current CEO of both Altavant and Enzyvant, is now CEO of the merged company.

The European Commission has recommended steps that — though not yet final — would require Illumina to “swiftly” unwind its controversial $7.1 billion Grail buyout.

The Commission delivered a “statement of objections” on Monday, detailing the process Illumina would need to take in divesting Grail, its blood testing spinout launched in 2016. Illumina re-acquired Grail back in August, despite criticism from both the FTC and EU.
