Dipex­i­um shares evis­cer­at­ed af­ter lead an­tibi­ot­ic flops on a full slate of PhI­II end­points

Ben­jamin A. Lip­sky, Dipex­i­um

The mi­cro­cap biotech Dipex­i­um Phar­ma­ceu­ti­cals $DPRX went pub­lic in 2014, promis­ing to ad­vance an im­por­tant new an­tibi­ot­ic cream in the clin­ic. But to­day, the lit­tle biotech was forced to con­cede that their lead pro­gram flopped bad­ly in two late-stage stud­ies, flunk­ing the pri­ma­ry as well as sec­ondary end­points.

Not on­ly was there no “mean­ing­ful dif­fer­ence” be­tween their an­tibi­ot­ic and stan­dard care for wound clo­sure rates among pa­tients with di­a­bet­ic foot ul­cers, it al­so wasn’t able to erad­i­cate bac­te­ria sig­nif­i­cant­ly bet­ter. Adding in­sult to in­jury, the com­pa­ny added that “se­ri­ous ad­verse events with Locilex in­clud­ed high­er than an­tic­i­pat­ed os­teomyelitis and cel­luli­tis in the Locilex arm of each study.”

The news evis­cer­at­ed its share price, which plunged 85% in pre-mar­ket trad­ing.

Dipex­i­um picked up the rights to Locilex from Ma­g­a­in­in Phar­ma­ceu­ti­cals, which tried and failed to win an FDA ap­proval in 1999. The Dipex­i­um crew re­for­mu­lat­ed the treat­ment and then tout­ed the FDA’s will­ing­ness to ap­prove the drug on a place­bo con­trolled Phase III pro­gram.

But none of that made any dif­fer­ence at all.

The New York-based biotech start­ed the day with a mar­ket cap of $132 mil­lion and went pub­lic at $12 a share. It closed yes­ter­day at $12.75.

Ben­jamin A. Lip­sky, the chair­man of the Phase III pro­gram, put the most op­ti­mistic face on this as pos­si­ble:

The re­sults of this study will pro­vide im­por­tant in­for­ma­tion re­gard­less of the out­come. This will in­clude a bet­ter un­der­stand­ing of the nat­ur­al course of di­a­bet­ic foot ul­cer and in­fec­tion, and a recog­ni­tion that some Mild DFI pa­tients may not need an­tibac­te­r­i­al treat­ment.  The ex­em­plary con­duct of the tri­al re­flects ex­treme­ly well on the par­tic­i­pat­ing in­ves­ti­ga­tors. We look for­ward to con­tin­u­ing analy­ses of the wealth of da­ta ac­cu­mu­lat­ed and to re­port more de­tails of our find­ings.

“The On­eStep tri­als were the first ever ‘place­bo’-con­trolled stud­ies con­duct­ed for mild­ly in­fect­ed di­a­bet­ic foot ul­cers,” said Dipex­i­um Ex­ec­u­tive Chair­man Robert J. DeLuc­cia in a state­ment. “In these stud­ies, the ‘place­bo’ was the cream ve­hi­cle with­out pex­i­ganan, the ac­tive phar­ma­ceu­ti­cal in­gre­di­ent in Locilex. These com­plex tri­als re­quired strin­gent stan­dard­ized wound care, in both study arms, in­clud­ing ul­cer de­bride­ment, dai­ly wound dress­ing changes and pres­sure off-load­ing de­vices. Since an­tibi­otics are gen­er­al­ly used by clin­i­cians to treat an in­fect­ed ul­cer, no clin­i­cal tri­al in di­a­bet­ic foot in­fec­tion has ever es­tab­lished a ‘re­sponse rate’ for an ul­cer in­fec­tion that had stan­dard­ized wound care but was un­treat­ed with an an­tibi­ot­ic.”

Turned back at the FDA, Im­muno­Gen is ax­ing 220 staffers, sell­ing pro­grams and hun­ker­ing down for a new PhI­II gam­ble

After being stymied by FDA regulators who were unconvinced by ImmunoGen’s $IMGN desperation shot at an accelerated OK based on a secondary endpoint, the struggling biotech is slashing its workforce, shuttering R&D projects and looking for buyers to pick up some of its experimental cancer assets as it goes back into a new Phase III with the lead drug.

We found out last month that the FDA had batted back their case for an accelerated approval of their antibody-drug conjugate mirvetuximab soravtansine, which had earlier failed a Phase III study for ovarian cancer. Now the other shoe is dropping.

As­traZeneca chal­lenges Roche on front­line SCLC af­ter seiz­ing an in­ter­im win — and Mer­ck may not be far be­hind

The crowded playing field in the PD-1/L1 marketing game is about to get a little more complex.

This morning AstraZeneca reported that its CASPIAN study delivered a hit in an interim readout for their PD-L1 Imfinzi combined with etoposide and platinum-based chemotherapy options for frontline cases of small cell lung cancer, a tough target which has already knocked back Bristol-Myers’ shot in second-line cases. The positive data  — which we won’t see before they roll it out at an upcoming scientific conference — give AstraZeneca excellent odds of a quick vault to challenging Roche’s Tecentriq-chemo combo, approved 3 months ago for frontline SCLC in a landmark advance.

“This is the first trial offering the flexibility of combining immunotherapy with different platinum-based regimens in small cell lung cancer, expanding treatment options,” noted AstraZeneca cancer R&D chief José Baselga in a statement.

Bridge­Bio takes crown for biggest biotech IPO of 2019, as fel­low uni­corn Adap­tive rais­es of­fer­ing size and price

Bridge­Bio Phar­ma and Adap­tive Biotech­nolo­gies have not just up­sized IPO of­fer­ings — the pair of uni­corns have al­so raised their of­fer­ing prices above the range, haul­ing in a com­bined $648.5 mil­lion.

Neil Ku­mar’s Bridge­Bio Phar­ma, found­ed in 2015, has a sta­ble of com­pa­nies fo­cused on dis­eases that are dri­ven by de­fects in a sin­gle gene — en­com­pass­ing der­ma­tol­ogy, car­di­ol­o­gy, neu­rol­o­gy, en­docrinol­o­gy, re­nal dis­ease, and oph­thal­mol­o­gy — and can­cers with clear ge­net­ic dri­vers. The start­up mill birthed a pletho­ra of firms such as Ei­dos, Navire, QED Ther­a­peu­tics and Pelle­Pharm, which func­tion as its sub­sidiaries.

Two biotech uni­corns swell pro­posed IPOs, eye­ing a $600M-plus wind­fall

We’ve been wait­ing for the ar­rival of Bridge­Bio’s IPO to top off the wave of new biotech of­fer­ings sweep­ing through Nas­daq at the end of H1. And now we learn that it’s been sub­stan­tial­ly up­sized.

Ini­tial­ly pen­ciled in at a uni­corn-sized $225 mil­lion, the KKR-backed biotech has spiked that to the neigh­bor­hood of $300 mil­lion, look­ing to sell 20 mil­lion shares at $14 to $16 each. That’s an added 5 mil­lion shares, re­ports Re­nais­sance Cap­i­tal, which fig­ures the pro­posed mar­ket val­u­a­tion for Neil Ku­mar’s com­pa­ny at $1.8 bil­lion.

No­var­tis holds back the copy­cat brigade's at­tack on its top drug fran­chise — for now

A fed­er­al judge has put a gener­ic chal­lenge to No­var­tis’ block­buster mul­ti­ple scle­ro­sis drug Gilenya on hold while a patent fight plays out in court.

Judge Leonard P. Stark is­sued a tem­po­rary in­junc­tion ear­li­er this week, forc­ing My­lan, Dr. Red­dy’s Lab­o­ra­to­ries and Au­robindo Phar­ma to shelve their launch plans to al­low the patent fight to pro­ceed. He ruled that al­low­ing the gener­ics in­to the mar­ket now would per­ma­nent­ly slash the price for No­var­tis, even if it pre­vails.

Af­ter rais­ing $158M, this up­start's founders have star back­ers and plans to break new ground in gene ther­a­py

Back in 2014, Stephanie Tagliatela opted to take an early exit out of her PhD program after working in Mark Bear’s lab at MIT, where she specialized in the synaptic connections between neuronal cells in the brain. She never finished that PhD, but she and fellow MIT student Kartik Ramamoorthi — who was on the founding team at Voyager — came away with some ideas for a gene therapy startup.

Today, fully 5 years later, she and Ramamoorthi are taking the wraps off of a $104 million mega-round designed to take the cumulative work of their preclinical formative stage for Encoded Therapeutics into human studies. They’ve now raised $158 million since starting out in Illumina’s incubator in the Bay Area, and they believe they are firmly on track to do something unique in gene therapy.

Ac­er Ther­a­peu­tics’ bid to re­pur­pose celipro­lol — a be­ta-block­er on the mar­ket for hy­per­ten­sion — as a treat­ment for a rare, in­her­it­ed con­nec­tive tis­sue dis­or­der has hit a se­vere set­back. The New­ton, Mass­a­chu­setts-based com­pa­ny on Tues­day said the FDA re­ject­ed the drug and has asked for an­oth­er clin­i­cal tri­al.

The com­pa­ny’s shares $AC­ER cratered near­ly 77% to $4.47 in Tues­day morn­ing trad­ing.
