In an­oth­er set­back for the be­lea­guered an­tibi­otics field, Nabri­va Ther­a­peu­tics says the FDA re­ject­ed its fos­fomycin for com­pli­cat­ed uri­nary tract in­fec­tions.

Im­por­tant­ly, the biotech says, reg­u­la­tors are not ask­ing for any new clin­i­cal or safe­ty da­ta. The com­plete re­sponse let­ter cen­ters around “is­sues re­lat­ed to fa­cil­i­ty in­spec­tions and man­u­fac­tur­ing de­fi­cien­cies at one of Nabri­va’s con­tract man­u­fac­tur­ers,” ac­cord­ing to a brief state­ment.

Over the next few weeks Nabri­va plans to re­quest a “Type A” meet­ing to dis­cuss the FDA’s find­ings. Shares $NR­BV are down 24% pre-mar­ket.

Across the in­dus­try, an­tibi­otics de­vel­op­ers and back­ers are suf­fer­ing from a new low in morale af­ter Achao­gen filed for bank­rupt­cy de­spite notch­ing an FDA ap­proval of its cU­TI drug, due to dis­ap­point­ing sales. And that fol­lows rounds of lay­offs at both Achao­gen and oth­er an­tibi­otics com­pa­nies like Melin­ta, with Big Phar­ma large­ly out of the pic­ture al­to­geth­er.

No­body would de­ny the ur­gent need for an­tibi­otics — just two days ago the UN is­sued an­oth­er re­port warn­ing of a “silent tsuna­mi” of an­timi­cro­bial re­sis­tance that threat­ens to kill 10 mil­lion peo­ple an­nu­al­ly by 2050 — but it’s in­creas­ing­ly hard to make a case for the R&D in­vest­ment when the prod­ucts are too niche to turn a prof­it in a world dom­i­nat­ed by gener­ics.

Nabri­va’s Con­tepo (IV fos­fomycin) is an old drug that’s been used out­side the US for over 45 years. Ac­cord­ing to the com­pa­ny, it can treat a num­ber of Gram-neg­a­tive and Gram-pos­i­tive bac­te­ria in­fec­tions, ac­tive against many com­mon mul­ti-drug re­sis­tant strains.

It bagged the drug via an ac­qui­si­tion of Za­vante, whose CEO Ted Schroed­er then took the helm of the new en­ti­ty. Nabri­va’s in-house lead pro­gram for com­mu­ni­ty-ac­quired bac­te­r­i­al pneu­mo­nia, lefa­mulin, is al­so un­der re­view with a PDU­FA date in Au­gust.

Weeks away from the results of ongoing US and China trials testing its experimental antiviral remdesivir, Gilead is going to trial the failed Ebola drug in a small group of coronavirus patients in England and Scotland. The United Kingdom is also home to a range of other therapeutic efforts, as the pandemic rages on across the globe.

On Tuesday, Southampton, UK-based startup Synairgen kicked off a mid-stage placebo-controlled study testing its experimental drug, SNG001 — an inhaled formulation of interferon-beta-1a — that has previously shown to be safe and effective in improving lung function in asthma patients with a respiratory viral infection in a pair of Phase II trials.

Just before Christmastime, Howard Federoff got a tip from Washington: There was a new virus in China. And this one could be bad.

News report of the virus had not yet appeared. Federoff, a neuroscientist, was briefed because years before, he was vetted as part of a group — he didn’t give a name for the group — to consult for the US government on emerging scientific issues. His day job, though, was CEO of Aspen Neurosciences, a Parkinson’s cell therapy startup that days before had come out of stealth mode and gave word to investors they were hoping to raise $70 million. That, Federoff realized, would be difficult if a pandemic shut down the global economy.

Despite worries about regulatory delays due to new work arrangements under Covid-19, the FDA appears intent to go full speed ahead with its everyday work, not only granting priority review to a stem cell therapy for acute graft versus host disease but also plotting an advisory committee meeting for it.

With a PDUFA date of September 30, the journey of the drug — remestemcel-L, or Ryoncil — could shed light on the agency’s capacity to facilitate drug development unrelated to Covid-19.
