Zo­genix shares are claw­ing back some of the val­ue they lost 2 months ago af­ter the FDA hit the biotech with a refuse-to-file no­tice on their ex­per­i­men­tal ther­a­py for Dravet syn­drome. 

Com­pa­ny ex­ecs said this morn­ing that they worked out reg­u­la­tors’  is­sues with the ap­pli­ca­tion for Fin­tepla, which cen­tered on a pair of big prob­lems: the ab­sence of non-clin­i­cal stud­ies need­ed to al­low as­sess­ment of the chron­ic ad­min­is­tra­tion of fen­flu­ramine and the in­clu­sion of an in­cor­rect ver­sion of a clin­i­cal dataset. Now they plan to re­sub­mit in Q3 af­ter get­ting off the hook on both scores — which trig­gered a sigh of re­lief among in­vestors.

Zo­genix stock climbed 27% be­fore the open­ing bell Thurs­day on hopes of a near-term sec­ond turn at bat. The biotech not­ed:

Based on the fi­nal meet­ing min­utes re­ceived, the FDA has agreed to Zo­genix’s plan to re­sub­mit the NDA for Fin­tepla with­out the in­clu­sion of the new chron­ic tox­i­c­i­ty stud­ies re­quest­ed in the RTF let­ter. With re­gards to the sec­ond is­sue, the com­pa­ny con­duct­ed and dis­cussed with the FDA a root cause analy­sis to ex­plain the in­cor­rect clin­i­cal dataset sub­mit­ted in the orig­i­nal NDA, and the FDA is in agree­ment with the com­pa­ny’s plan for re­sub­mis­sion of the datasets in the NDA.

This time around, though, Zo­genix’s team will not have the ben­e­fit of a break­through ther­a­py des­ig­na­tion to boast about. With 2 drugs on the mar­ket, the FDA no longer felt that their drug qual­i­fied. But the com­pa­ny is still hold­ing out hopes for a pri­or­i­ty re­view.

So­cial im­age: Shut­ter­stock

Since losing a controversial court case over orphan drug exclusivity last year, the FDA’s Office of Orphan Products Development has remained entirely silent on orphan exclusivity for any product approved since last November, leaving many sponsors in limbo on what to expect.

That silence means that for more than 70 orphan-designated indications for more than 60 products, OOPD has issued no public determination on the seven-year orphan exclusivity in the Orange Book, and no new listings of orphan exclusivity appear in OOPD’s searchable database, as highlighted recently by George O’Brien, a partner in Mayer Brown’s Washington, DC office.

As the global biologics market is expected to hit nearly the half-trillion-dollar mark this year, new JAMA research points to the importance of timely biosimilar entry, particularly as fewer biosimilars are entering the US than in Europe, and as monthly treatment costs for biosimilars were “substantially higher” in the US compared with Germany and Switzerland.

Among the three countries, biosimilar market share at launch was highest in Germany, but increased at the fastest rate in the US, the authors from the University of Zurich’s Institute of Law wrote in JAMA Network Open today.

The European Medicines Agency said Friday that it’s pulling from all European markets pholcodine-containing medicines, which are an opioid used in adults and children for the treatment of dry cough and in combo with other drugs as a treatment for cold and flu.

The decision to pull the medicines comes as the EMA points to the results from the recent ALPHO study, which show that use of pholcodine during the 12 months preceding anesthesia is linked to a risk of an anaphylactic reaction related to the neuromuscular blocking agents (NMBAs) used (with an adjusted OR of 4.2, and a 95% confidence interval of 2.5 to 6.9).

The Houston-based biotech Salarius Pharmaceuticals is lifting the cover on data from a Phase I/II trial for a drug currently on voluntary hold after a patient death, and the results appear to have underwhelmed investors.

Salarius’ candidate, dubbed seclidemstat, is an oral LSD1 inhibitor that is meant to treat Ewing sarcoma and FET-rearranged sarcomas in patients under 12 years old. The biotech had presented data with 13 patients with “first- and second-relapse Ewing sarcoma” who were treated in combination with topotecan and cyclophosphamide.
