Pfiz­er, Mer­ck KGaA re­port their lat­est set­back with check­point con­tender Baven­cio

Mer­ck KGaA and their part­ners at Pfiz­er have an­oth­er big set­back to re­port for their PD-L1 check­point drug Baven­cio.

The check­point ei­ther alone or in com­bi­na­tion with chemother­a­py failed to hit ei­ther the over­all sur­vival or pro­gres­sion-free sur­vival end­points in their Phase III JAVELIN Ovar­i­an 200 study for drug-re­sis­tant ovar­i­an can­cer. The news comes 9 months af­ter re­searchers al­so re­port­ed a fail for their check­point on sec­ond-line lung can­cer, lead­ing some an­a­lysts to con­clude that their big Baven­cio pro­gram was look­ing like a run­ner-up in the in­tense­ly com­pet­i­tive field.

Baven­cio al­so failed a Phase III study for gas­tric can­cer, putting a crimp in their plans to ramp up sales and rais­ing doubts about their abil­i­ty to com­pete against lead­ers like Mer­ck and Bris­tol-My­ers Squibb.

The haz­ard ra­tio in the lat­est study un­der­scored a mea­ger 5% re­duc­tion in risk on over­all sur­vival for Baven­cio alone and an 11% drop for the com­bi­na­tion arm. That was a flat fail­ure. But re­searchers al­so teased out a pos­i­tive p-val­ue for the com­bi­na­tion arm on pro­gres­sion-free sur­vival.

Key­ing on the pos­i­tive, Mer­ck KGaA R&D chief Lu­ciano Ros­set­ti said that they would con­tin­ue to ex­plore the num­bers.

It hasn’t all been bad news with Baven­cio. Just a cou­ple of months ago their drug came though for re­nal cell car­ci­no­ma pa­tients, set­ting up some speedy ap­pli­ca­tions for mar­ket­ing ap­proval. Re­searchers say it helped PD-L1 ex­press­ing pa­tients and the full pop­u­la­tion, demon­strat­ing a sig­nif­i­cant PFS ben­e­fit com­pared to a con­trol arm treat­ed with Su­tent.

Chris Boshoff

Chris Boshoff, the head of I/O at Pfiz­er Glob­al Prod­uct De­vel­op­ment, had this to say to­day:

We ini­ti­at­ed the JAVELIN Ovar­i­an 200 tri­al as the first Phase III study of a check­point in­hibitor in the plat­inum-re­sis­tant or -re­frac­to­ry set­ting rec­og­niz­ing these pa­tients have the most press­ing need for new treat­ment op­tions. The re­sults speak to the sig­nif­i­cant chal­lenges these women face.

AveX­is sci­en­tif­ic founder fires back at No­var­tis CEO Vas Narasimhan, 'cat­e­gor­i­cal­ly de­nies any wrong­do­ing'

Brian Kaspar’s head was among the first to roll at Novartis after company execs became aware of the fact that manipulated data had been included in its application for Zolgensma, now the world’s most expensive therapy.

But in his first public response, the scientific founder at AveXis — acquired by Novartis for $8.7 billion — is firing back. And he says that not only was he not involved in any wrongdoing, he’s ready to defend his name as needed.

I reached out to Brian Kaspar after Novartis put out word that he and his brother Allen had been axed in mid-May, two months after the company became aware of the allegations related to manipulated data. His response came back through his attorneys.

We­bi­nar: Re­al World End­points — the brave new world com­ing in build­ing fran­chise ther­a­pies

Several biopharma companies have been working on expanding drug labels through the use of real world endpoints, combing through the data to find evidence of a drug’s efficacy for particular indications. But we’ve just begun. Real World Evidence is becoming an important part of every clinical development plan, in the soup-through-nuts approach used in building franchises.

I’ve recruited a panel of 3 top experts in the field — the first in a series of premium webinars — to look at the practical realities governing what can be done today, and where this is headed over the next few years, at the prodding of the FDA.

Video: Putting the AI in R&D — with Badhri Srini­vasan, Tony Wood, Rosana Kapeller, Hugo Ceule­mans, Saurabh Sa­ha and Shoibal Dat­ta

During BIO this year, I had a chance to moderate a panel among some of the top tech experts in biopharma on their real-world use of artificial intelligence in R&D. There’s been a lot said about the potential of AI, but I wanted to explore more about what some of the larger players are actually doing with this technology today, and how they see it advancing in the future. It was a fascinating exchange, which you can see here. The transcript has been edited for brevity and clarity. — John Carroll

UP­DAT­ED: As­traZeneca’s Imfinzi/treme com­bo strikes out — again — in lung can­cer. Is it time for last rites?

AstraZeneca bet big on the future of their PD-L1 Imfinzi combined with the experimental CTLA-4 drug tremelimumab. But once again it’s gone down to defeat in a major Phase III study — while adding damage to the theory involving targeting cancer with a high tumor mutational burden.

Early Wednesday the pharma giant announced that their NEPTUNE study had failed, with the combination unable to beat standard chemo at overall survival in high TMB cases of advanced non-small cell lung cancer. We won’t get hard data until later in the year, but the drumbeat of failures will call into question what — if any — future this combination can have left.

Cowen, Per­cep­tive lead $79.5M Se­ries B for 's­tand­out' biotech shep­herd­ing on­colyt­ic virus to clin­ic

As several Big Pharma players secure biotech partners in the oncolytic virus space for new immuno-oncology combos, Cowen and Perceptive Advisors have come out with their own bet on a startup that promises to shine.

The marquee investors are joining MPM, Deerfield, Celgene, Astellas, Arkin and UBS in backing the drug developer, Oncorus, which will now deploy the $79.5 million in Series B cash toward clinical development of its lead program. Other new investors include Surveyor Capital, Sphera Funds, IMM Investment, QUAD Investment Management, UTC Investment, SV Investment Corp and Shinhan Investment-Private Equity, the last five of which are Korean-based funds.

Fu­til­i­ty analy­sis au­gurs de­feat in piv­otal tri­al test­ing of Nu­Cana's lead drug in metasta­t­ic pan­cre­at­ic can­cer

Nearly two years after making its public debut, UK-based NuCana’s mission to make chemotherapies more potent and safer was dealt a blow, after a pivotal study testing its lead experimental drug halted enrollment in a hard-to-treat advanced form of cancer, following a futility analysis.

The drug, Acelarin, is being evaluated for use in metastatic pancreatic cancer patients who were not considered suitable for combination chemotherapy. In the late-stage ACELARATE study — which compared the experimental drug against the chemotherapy gemcitabine — 200 patients had been enrolled by the sponsor, Clatterbridge Cancer Centre, before an analysis from an independent safety and data monitoring panel suggested the study’s main goal would not be met.

UP­DAT­ED: Pay­back? An­a­lysts say Sarep­ta was blind­sided by an FDA re­jec­tion dri­ven by reg­u­la­to­ry re­venge

In one of the least anticipated moves of the year, the FDA has rejected Sarepta’s application for an accelerated approval of its Duchenne MD drug golodirsen after fretting over safety issues.

In a statement that arrived after the bell on Monday, Sarepta explained the CRL, saying:

Af­ter a posse of Wall Street an­a­lysts pre­dict a like­ly new win for Sarep­ta, we're down to the wire on a crit­i­cal FDA de­ci­sion

As Bloomberg notes, most of the Wall Street analysts that cover Sarepta $SRPT are an upbeat bunch, ready to cheer on the team when it comes to their Duchenne MD drugs, or offer explanations when an odd setback occurs — as happened recently with a safety signal that was ‘erroneously’ reported last week.
