No OS ben­e­fit? No prob­lem. FDA pan­el backs use of Lyn­parza in pan­cre­at­ic can­cer

As As­traZeneca works to tight­en its hold on the PARP mar­ket, an in­de­pen­dent pan­el of ad­vi­sors to the FDA cau­tious­ly en­dorsed Lyn­parza’s use in cer­tain pan­cre­at­ic can­cer pa­tients, even though it failed to help pa­tients live longer.

On Tues­day, pan­elists vot­ed 7-5 to rec­om­mend the drug for main­te­nance use in pa­tients with germline BR­CA-mu­tat­ed metasta­t­ic ade­no­car­ci­no­ma of the pan­creas, whose dis­ease has not pro­gressed on at least 16 weeks of first-line plat­inum-based chemother­a­py. Glob­al­ly, germline BR­CAm pan­cre­at­ic can­cer ac­counts for 5-7% of all cas­es.

The FDA is not oblig­ed to ac­cept the rec­om­men­da­tions of the pan­el but typ­i­cal­ly does. The agency is ex­pect­ed to make its fi­nal de­ci­sion in the fourth quar­ter.

Lyn­parza, known chem­i­cal­ly as ola­parib, is al­ready ap­proved as a main­te­nance agent in mul­ti­ple lines of ther­a­py for ovar­i­an can­cer, as well as a metasta­t­ic breast can­cer ther­a­py. It is al­so ex­pect­ed to se­cure ap­proval in prostate can­cer next year.

The pan­cre­at­ic can­cer ap­pli­ca­tion was based on the 154-pa­tient, place­bo-con­trolled PO­LO tri­al. Lyn­parza in­duced a sta­tis­ti­cal­ly sig­nif­i­cant im­prove­ment in pro­gres­sion-free sur­vival (PFS) (95% con­fi­dence in­ter­val: 0.35, 0.81; p=0.0035) — cor­re­spond­ing to a 3.6-month im­prove­ment in me­di­an PFS. There was al­so ev­i­dence of tu­mor shrink­age, in­di­cat­ed by the dif­fer­ence in the over­all re­sponse rate of 9.9% ver­sus the place­bo arm. How­ev­er, no ef­fect on over­all sur­vival (OS) was ob­served.

In a brief­ing doc­u­ment post­ed days ear­li­er, FDA staff high­light­ed their con­cerns about the drug’s use in this pan­cre­at­ic can­cer pop­u­la­tion. Re­view­ers took is­sue that the pri­ma­ry end­point was as­sessed on the ba­sis of tu­mor mea­sure­ments, which can dif­fer among tu­mor set­tings and are sub­ject to as­sess­ment bias. In ad­di­tion, they ques­tioned whether the tri­al was ‘ad­e­quate­ly con­trolled’ giv­en its small size. An­oth­er source of un­cer­tain­ty, they said, was the lim­i­ta­tions of cur­rent imag­ing tech­nol­o­gy to ac­cu­rate­ly mea­sure the ef­fect on PFS.

“Giv­en these con­cerns re­gard­ing the ac­cu­ra­cy of tu­mor mea­sure­ment in pan­cre­at­ic can­cer, FDA ap­proval of all pre­vi­ous drugs for the treat­ment of pan­cre­at­ic can­cer has been based on ef­fects on OS, an end­point for which as­sess­ment bias and lim­i­ta­tions in the ac­cu­ra­cy of tu­mor mea­sure­ment by imag­ing tech­nol­o­gy are not present,” the re­port said.

“FDA ac­knowl­edges that a dif­fer­ence in PFS fa­vor­ing the ola­parib arm has been demon­strat­ed in the PO­LO tri­al. How­ev­er, there is un­cer­tain­ty that the ob­served mag­ni­tude of the treat­ment ef­fect on PFS ac­cu­rate­ly rep­re­sents the true treat­ment ef­fect…”

As­traZeneca and part­ner Mer­ck’s Lyn­parza, akin to GSK’s Ze­ju­la and Clo­vis On­col­o­gy’s Rubra­ca, is a poly-ADP ri­bose poly­merase (PARP) in­hibitor. PARP is a pro­tein used by dam­aged cells to ini­ti­ate re­pair, and by thwart­ing it, the class of drugs is en­gi­neered to pre­vent can­cer cells from re­pair­ing them­selves, there­by cat­alyz­ing their de­struc­tion.

“While there are cur­rent­ly 4 ap­proved PARP in­hibitors in the US and Eu­rope, As­traZeneca and part­ner Mer­ck have es­tab­lished the drug as the mar­ket leader through a com­bi­na­tion of mar­ket­ing ex­per­tise and strate­gic tri­al de­signs,” SVB Leerink’s An­drew Berens wrote in a note last month.

“We ex­pect the drug to re­main the mar­ket leader…with po­ten­tial ex­pan­sion to oth­er tu­mors like pan­cre­at­ic, blad­der and lung,” he said, adding that ex­perts ex­pect Lyn­parza to con­tin­ue as the dom­i­nant PARP in­hibitor un­til its loss of ex­clu­siv­i­ty, which is mod­eled for 2029.

2019 Trin­i­ty Drug In­dex Eval­u­ates Ac­tu­al Com­mer­cial Per­for­mance of Nov­el Drugs Ap­proved in 2016

Fewer Approvals, but Neurology Rivals Oncology and Sees Major Innovations

This report, the fourth in our Trinity Drug Index series, outlines key themes and emerging trends in the industry as we progress towards a new world of targeted and innovative products. It provides a comprehensive evaluation of the performance of novel drugs approved by the FDA in 2016, scoring each on its commercial performance, therapeutic value, and R&D investment (Table 1: Drug ranking – Ratings on a 1-5 scale).

UP­DAT­ED: FDA’s golodirsen CRL: Sarep­ta’s Duchenne drugs are dan­ger­ous to pa­tients, of­fer­ing on­ly a small ben­e­fit. And where's that con­fir­ma­to­ry tri­al?

Back last summer, Sarepta CEO Doug Ingram told Duchenne MD families and investors that the FDA’s shock rejection of their second Duchenne MD drug golodirsen was due to some concerns regulators raised about the risk of infection and the possibility of kidney toxicity. But when pressed to release the letter for all to see, he declined, according to a report from BioPharmaDive, saying that kind of move “might not look like we’re being as respectful as we’d like to be.”

He went on to assure everyone that he hadn’t misrepresented the CRL.

But Ingram’s public remarks didn’t include everything in the letter, which — following the FDA’s surprise about-face and unexplained approval — has now been posted on the FDA’s website and broadly circulated on Twitter early Wednesday.

The CRL raises plenty of fresh questions about why the FDA abruptly decided to reverse itself and hand out an OK for a drug a senior regulator at the FDA believed — 5 months ago, when he wrote the letter — is dangerous to patients. It also puts the spotlight back on Sarepta $SRPT, which failed to launch a confirmatory study of eteplirsen, which was only approved after a heated internal controversy at the FDA. Ellis Unger, director of CDER’s Office of Drug Evaluation I, notes that study could have clarified quite a lot about the benefit and risks associated with their drugs — which can cost as much as a million dollars per patient per year, depending on weight.

How to cap­i­talise on a lean launch

For start-up biotechnology companies and resource stretched pharmaceutical organisations, launching a novel product can be challenging. Lean teams can make setting a launch strategy and achieving your commercial goals seem like a colossal undertaking, but can these barriers be transformed into opportunities that work to your brand’s advantage?
We spoke to Managing Consultant Frances Hendry to find out how Blue Latitude Health partnered with a fledgling subsidiary of a pharmaceutical organisation to launch an innovative product in a
complex market.
What does the launch environment look like for this product?
FH: We started working on the product at Phase II and now we’re going into Phase III trials. There is a significant unmet need in this disease area, and everyone is excited about the launch. However, the organisation is still evolving and the team is quite small – naturally this causes a little turbulence.

Wuhan virus out­break trig­gers in­evitable small-biotech ral­ly

Every few years, a public health crisis (think Ebola, Zika) spurred by a rogue pathogen triggers a small-biotech rally, as drugmakers emerge from the woodwork with ambitious plans to treat the mounting outbreak. In most cases, that enthusiasm never quite delivers.

Things are no different, as the coronavirus outbreak in Wuhan, China takes hold. There have been close to 300 confirmed human infections in China, and at least four deaths. Coronaviruses are a large family of viruses, which include MERS and SARS. On Tuesday, the CDC reported the virus was detected in a US traveler returning from Wuhan.

Brex­it fears, Wood­ford woes over­shad­owed UK biotech and cut 2019 fi­nanc­ing by al­most half

The venture tide might have subsided, the IPO window may be closing and certain listed biotechs may be having a tough time amid Neil Woodford’s well-publicized demised, but there’s still plenty to celebrate in the UK BioIndustry Association’s eyes.

Overall investment in UK biotech last year fell from the record-breaking £2.2 billion levels of 2018 to £1.3 billion — including £679 million in venture capital, a meager £64 million in IPOs plus £596 million when you add up all public financings, according to a new report from the BIA.

Blue­print Med­i­cines po­ten­tial­ly de­lays Ay­vak­it de­ci­sion; Con­trol beats treat­ment in mesothe­lioma tri­al

→ Blueprint Medicines filed an amendment to its application to get the gastrointestinal stromal tumor (GIST) drug Ayvakit approved in fourth-line GIST, the company disclosed in the prospectus for a new $325 million public offering.  Blueprint got a big accelerated OK on the drug this month in a particular mutation, but because the FDA decided to split their review in two, they didn’t hear on fourth-line GIST. They were supposed to hear before February 14, but this amendment could push that date back by 3 months. Blueprint wrote that the amendment is designed to allow the company to comply with the FDA’s request for data from the Phase III VOYAGER before they give a judgment.

Io­n­is, Akcea boost­ed by a pos­i­tive PhII for their No­var­tis castoff car­dio drug — and they plan to push ahead in­to piv­otals

Late last year Novartis abandoned a cardio drug from Ionis’ spinoff Akcea just after the pharma giant snapped up inclisiran, going the RNAi way in guarding against heart disease in the $9.7 billion Medco buyout.

Now the pharma goliath — which is headed down the PCSK9 road with a drug it believes can be used in a mass population — can get a clearer picture of just what they gave up.

Akcea $AKCA and the mother company $IONS put out a statement early Wednesday saying that their Phase II study of AKCEA-APOCIII-LR delivered solid efficacy data, with the high dose clearly outperforming placebo in significantly reducing triglycerides as a means to cutting the risk of cardiovascular disease. In addition, investigators concluded that the drug slashed apoC-III, very low-density lipoprotein and remnant cholesterol while boosting “good” HDL levels.

GSK’s ‘break­through’ BC­MA can­cer drug gets a pri­or­i­ty re­view — and a big win for the on­col­o­gy R&D team

After largely whiffing the past 2 years on the pharma R&D front, GlaxoSmithKline research chief Hal Barron has seized boasting rights to a key win that puts them back in the cancer drug development game.
