Durect shares stum­ble as top drug fails mid-stage tri­al

Durect’s shares are crash­ing again.

Two years af­ter a No­var­tis-part­nered Phase III flop sent them in­to pen­ny stock ter­ri­to­ry, Durect has failed an­oth­er tri­al for a top can­di­date. This time, though, the biotech may have bet­ter fall­back op­tions.

DUR-928, the lead drug in Durect’s epi­ge­net­ic reg­u­la­tor pro­gram, was test­ed in 28 plaque pso­ri­a­sis pa­tients. Each pa­tient served as their own con­trol, with the drug ad­min­is­tered to one arm and the place­bo ad­min­is­tered to the oth­er. The good news was that there was no mean­ing­ful dif­fer­ence in ad­verse ef­fects be­tween the two arms. The bad news was there didn’t seem to be much of a dif­fer­ence at all, as DUR-928 “did not demon­strate a ben­e­fit over ve­hi­cle (place­bo)” and missed all pri­ma­ry and sec­ondary end­points.

Durect’s shares $DR­RX, which had been ris­ing for months, fell 34% to $2.50.

Durect an­nounced it is dis­con­tin­u­ing the top­i­cal pso­ri­a­sis pro­gram, but that is on­ly one of the three in­di­ca­tions in which the biotech is test­ing DUR-928. They al­so have an in­jectable form of the drug in Phase II for al­co­holic he­pati­tis and an oral form in Phase I for non­al­co­holic steato­hep­ati­tis, bet­ter known as NASH. Pos­i­tive re­sults came out for the al­co­holic he­pati­tis pro­gram in No­vem­ber; pa­tients in the treat­ment arm saw a sta­tis­ti­cal­ly sig­nif­i­cant re­duc­tion in biliru­bin, the yel­low sub­stance in bile that gives pa­tients the well-known jaun­diced look.

The tri­al fail­ure comes as the biotech pre­pares for a key reg­u­la­to­ry date for the No­var­tis-part­nered drug, a post-op­er­a­tion non-opi­oid pain drug now called Posimir. The drug has had a rocky his­to­ry, in­clud­ing a 2012 tri­al fail­ure, a 2014 CRL from the FDA, and a 2016 re­quest from the agency to change their tri­al de­sign, help­ing lead to the 2017 fail­ure.

Durect re­spond­ed to the CRL this past June, repack­ag­ing their orig­i­nal sub­mis­sion to fo­cus on six tri­als. It’s not yet clear what the FDA will say, but the new sub­mis­sion con­vinced the agency to de­lay an ear­ly PDU­FA date of De­cem­ber 27 and give the biotech an ad­comm meet­ing for lat­er this month.

The Durect pro­gram with the most po­ten­tial, though, may end up be­ing their long-act­ing in­jectable HIV can­di­date, part of their SABER plat­form. Gilead paid $25 mil­lion up­front and promised mil­lions more in mile­stones to latch on­to that plat­form. They op­tioned the HIV drug in Sep­tem­ber for a $10 mil­lion pay­ment.

MedTech clinical trials require a unique regulatory and study design approach and so engaging a highly experienced CRO to ensure compliance and accurate data across all stages is critical to development milestones.

Gold for adults, sil­ver for in­fants: Pfiz­er's Pre­vnar 2.0 head­ed to FDA months af­ter Mer­ck­'s green light

Pfizer was first to the finish line for the next-gen pneumococcal vaccine in adults, but Merck beat its rival with a jab for children in June.

Now, two months after Merck’s 15-valent Vaxneuvance won the FDA stamp of approval for kids, Pfizer is out with some late-stage data on its 20-valent shot for infants.

Known as Prevnar 20 for adults, Pfizer’s 20vPnC will head to the FDA by the end of this year for an approval request in infants, the Big Pharma said Friday morning. Discussions with the FDA will occur first and more late-stage pediatric trials are expected to read out soon, informing the regulatory pathway in other countries and regions.

No­var­tis re­ports two pa­tient deaths af­ter treat­ment with Zol­gens­ma

Two children with spinal muscular atrophy have died after receiving Novartis’ Zolgensma, a gene therapy designed as a one-time treatment for the rare fatal disease.

The deaths, which resulted from acute liver failure, occurred in Russia and Kazakhstan, Novartis confirmed in a statement to Endpoints News. Having notified health authorities across all the markets where Zolgensma is available, it will update the drug label “to specify that fatal acute liver failure has been reported,” a spokesperson wrote.

House pass­es his­toric drug pric­ing re­forms, lin­ing up decades-in-the-mak­ing win for Biden and De­moc­rats

The US House of Representatives today voted along party lines (all Dems voted for it), 220-207 to pass new, wide-ranging legislation that will allow Medicare drug price negotiations for the first time ever, and cap seniors’ drug expenses to $2,000 per year and seniors’ insulin costs at $35 per month.

Setting up a major victory for President Joe Biden, representatives returned from their summer recess to pass the Inflation Reduction Act, even as many noted the bill would only modestly reduce inflation.

Sen­ate Fi­nance chair con­tin­ues his in­ves­ti­ga­tion in­to phar­ma tax­es with re­quests for Am­gen

Amgen is the latest pharma company to appear on the radar of Senate Finance Committee Chair Ron Wyden (D-OR), who is investigating the way pharma companies are using subsidiaries in low- or zero-tax countries to lower their tax bills.

Like its peers Merck, AbbVie and Bristol Myers Squibb, Wyden notes how Amgen uses its Puerto Rico operations to consistently pay tax rates that are substantially lower than the U.S. corporate tax rate of 21%, with an effective tax rate of 10.7% in 2020 and 12.1% in 2021.

FDA ap­proves sec­ond in­di­ca­tion for As­traZeneca and Dai­ichi's En­her­tu in less than a week

AstraZeneca and Daiichi Sankyo’s antibody-drug conjugate Enhertu scored its second approval in less than a week, this time for a subset of lung cancer patients.

Enhertu received accelerated approval on Thursday to treat adults with unresectable or metastatic non-small cell lung cancer (NSCLC) whose tumors have activating HER2 (ERBB2) mutations, and who have already received a prior systemic therapy.

J&J to re­move talc prod­ucts from shelves world­wide, re­plac­ing with corn­starch-based port­fo­lio

After controversially spinning out its talc liabilities and filing for bankruptcy in an attempt to settle 38,000 lawsuits, Johnson & Johnson is now changing up the formula for its baby powder products.

J&J is beginning the transition to an all cornstarch-based baby powder portfolio, the pharma giant announced on Thursday — just months after a federal judge ruled in favor of its “Texas two-step” bankruptcy to settle allegations that its talc products contained asbestos and caused cancer. An appeals court has since agreed to revisit that case.

CSL brings Se­qirus, Vi­for un­der par­ent um­brel­la brand in iden­ti­ty re­vamp

CSL is gathering its brands under the family name umbrella, renaming its vaccine and newly acquired nephrology specialty businesses with the parent initials.

CSL Seqirus and CSL Vifor join CSL Plasma and CSL Behring as the four now uniformly branded business units of the global biopharma. The Seqirus vaccine division was formed in 2015 with the combination of bioCSL and its purchase of Novartis’ flu vaccine business. CSL picked up Vifor Pharma late last year in an $11.7 billion deal for the nephrology, iron deficiency and cardio-renal drug developer.
