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.

Biohaven is at risk of making a habit of disappointing its investors. 

Late Friday the biotech $BHVN reported that the FDA had rejected its application for riluzole, an old drug that they had made over into a sublingual formulation that dissolves under the tongue. According to Biohaven, the FDA had a problem with the active ingredient used in a bioequivalence study back in 2017, which they got from the Canadian drugmaker Apotex.

Let the long battle for biosimilars in the cancer space begin.

Amgen has launched its Avastin and Herceptin copycats — licensed from the predecessors of Allergan — almost two years after the FDA had stamped its approval on Mvasi (bevacizumab-awwb) and three months after the Kanjinti OK (trastuzumab-anns). While the biotech had been fielding biosimilars in Europe, this marks their first foray in the US — and the first oncology biosimilars in the country.

→ On the same day it announced a $17.5 million Series C, life sciences and health data company Seer unveiled that it had lured former FDA commissioner and ex-CMS administrator Mark McClellan on to its board. “Mark’s deep understanding of the health care ecosystem and visionary insights on policy reform will be crucial in informing our thinking as we work to bring our liquid biopsy and life sciences products to market,” said Seer chief and founder Omid Farokhzad in a statement.

Gilead CEO Daniel O’Day’s new task hunting up a CSO for the company isn’t stopping the industry’s dominant antiviral player from doing pipeline deals.

The big biotech today snapped up 3 preclinical antiviral programs from pharma giant Novartis, with drugs promising to treat human rhinovirus, influenza and herpes viruses. We don’t know what the upfront is, but the back end has $291 million in milestones baked in.
