Third time un­lucky: Lipocine's lat­est quest to mar­ket their oral testos­terone drug snubbed again by FDA

Lipocine’s lat­est at­tempt at se­cur­ing ap­proval for its oral testos­terone drug has fiz­zled yet again.

The Utah-based drug de­vel­op­er on Mon­day said the FDA has spurned its mar­ket­ing ap­pli­ca­tion, in­di­cat­ing that some ef­fi­ca­cy da­ta on the drug, Tlando, was not up to scratch to treat male hy­pog­o­nadism, a con­di­tion char­ac­ter­ized by low pro­duc­tion of the hor­mone testos­terone, which is re­spon­si­ble for main­tain­ing mus­cle bulk, bone growth, and sex­u­al func­tion.

Shares of the Salt Lake City com­pa­ny $LPCN cratered more than 69% to 84 cents in morn­ing trad­ing.

Testos­terone treat­ments such as skin patch­es, short-act­ing in­jec­tions, and top­i­cal gels are cur­rent­ly on the mar­ket. The space is well cov­ered by in­sur­ers and is grow­ing, gen­er­at­ing some 7.2 mil­lion pre­scrip­tions last year, ac­cord­ing to Cowen an­a­lysts. But their pop­u­lar­i­ty in the ag­ing male de­mo­graph­ic has be­come a prob­lem for some biotechs in the field, with reg­u­la­tors re­ject­ing a num­ber of ap­pli­ca­tions in re­cent years.

In­tra­mus­cu­lar in­jec­tions are of­ten the first-line testos­terone re­place­ment ther­a­py (TRT) modal­i­ty due to the fact that they have long been gener­ic, be­fore grad­u­at­ing to the brand­ed top­i­cal prod­ucts (or even the gener­ic top­i­cals, which car­ry on­ly mod­est dis­counts to brand­ed An­dro­Gel), the Cowen an­a­lysts wrote in April. “The top­i­cal prod­ucts such as Ab­b­Vie’s An­dro­Gel and Lil­ly’s Ax­iron ap­pear to be read­i­ly ac­cessed, de­spite their brand­ed/brand­ed gener­ic pric­ing.”

Tlando is de­signed to avert the is­sues that plague the ex­ist­ing top­i­cal and in­jectable prod­ucts. Lipocine’s big ri­val, Clarus Ther­a­peu­tics, in March, won FDA ap­proval for its oral prod­uct, Jaten­zo. Lipocine and Clarus have been locked in lit­i­ga­tion re­lat­ed to in­tel­lec­tu­al prop­er­ty as­so­ci­at­ed with their re­spec­tive ther­a­pies.

Months ago, Lipocine said a tri­al is set to be­gin in Au­gust 2020 as part of its patent in­fringe­ment law­suit against Clarus’s Jaten­zo, re­lat­ing to six of Lipocine’s U.S. patents.  In the mean­time, Lipocine plans to seek a per­ma­nent in­junc­tion for Clarus’s al­leged in­fringe­ment.

Lipocine has been scarred time and time again in its bat­tle to bring Tlando to mar­ket. The com­pa­ny re­ceived its first re­jec­tion from the FDA in 2016, about a year af­ter the agency tight­ened its scruti­ny of TRT prod­ucts in gen­er­al. The reg­u­la­tor in March 2015 asked man­u­fac­tur­ers to tweak their la­bels to re­flect that TRT prod­ucts are on­ly ap­proved for men with cer­tain med­ical con­di­tions, and not for ag­ing-re­lat­ed low testos­terone; and that da­ta sug­gest TRT use leads to an in­creased risk of heart at­tacks and strokes.

In 2016, the agency in­di­cat­ed it was not com­fort­able with the Tlando dos­ing al­go­rithm. “The pro­posed titra­tion scheme for clin­i­cal prac­tice was sig­nif­i­cant­ly dif­fer­ent from the titra­tion scheme used in the Phase 3 tri­al lead­ing to dis­cor­dance in titra­tion de­ci­sions be­tween the Phase 3 tri­al and re­al-world clin­i­cal prac­tice,” Lipocine cit­ed the FDA say­ing in a state­ment.

Lipocine re­sub­mit­ted a mar­ket­ing ap­pli­ca­tion in 2017. In an FDA staff re­view that fol­lowed in 2018, the agency said it had rec­om­mend­ed that the com­pa­ny con­duct a new Phase III tri­al that tests the dose titra­tion scheme pro­posed for mar­ket­ing. In­stead, Lipocine chose to con­duct two new sin­gle-arm late-stage tri­als, each test­ing a dif­fer­ent dose of Tlando (150 mg thrice-dai­ly and 225 mg twice-dai­ly) with­out titra­tion. The 150 mg tri­al failed, but the 225 mg dose made the cut.

FDA pan­elists al­so ex­pressed oth­er con­cerns, in­clud­ing that the orig­i­nal late-stage tri­al up­on which Lipocine had based its ap­pli­ca­tion on did not meet one or none of the three sec­ondary end­points that as­sess for un­ac­cept­ably high max­i­mal ex­po­sures to testos­terone; the drug’s im­pact on the pa­tient’s blood pres­sure and heart rate; and whether Tlando was def­i­nite­ly restor­ing testos­terone and its ma­jor metabo­lites in­to nor­mal range.

Days lat­er, an in­de­pen­dent pan­el of ad­vi­sors to the FDA al­so sug­gest­ed their dis­com­fort with the drug. Over­all, thir­teen pan­elists vot­ed against the ben­e­fit/risk pro­file of Tlando, while six vot­ed in fa­vor. Un­sur­pris­ing­ly, the FDA hand­ed Lipocine an­oth­er re­jec­tion.

So Lipocine con­duct­ed an­oth­er study, a small 24-pa­tient tri­al to de­fin­i­tive­ly show that the drug was de­fin­i­tive­ly restor­ing testos­terone lev­els, us­ing tri­al pro­to­col the FDA was look­ing for. But on Mon­day, the FDA’s CRL flagged a prob­lem the com­pa­ny had failed to deal with from the start: that the orig­i­nal ef­fi­ca­cy tri­al failed to show the drug clear­ing three sec­ondary end­points for max­i­mal testos­terone con­cen­tra­tions.

The com­pa­ny plans to meet with the agency to fig­ure out its next steps.

Gene ther­a­py pi­o­neer Kathy High has left Spark af­ter com­plet­ing $4.3B union with Roche

Kathy High dedicated the past seven years of her life shepherding experimental gene therapies she’s developed at Children’s Hospital of Philadelphia toward the market as president and head of R&D at Spark Therapeutics. Now that the biotech startup is fully absorbed into Roche — with an FDA approval, a $4.3 billion buyout and a promising hemophilia program to boast — she’s ready to move on.

Roche confirmed her departure with Endpoints News and noted “she will take some well-deserved time off and then will begin a new chapter in a sabbatical at a university.”

The fourth CGRP mi­graine drug is here. Time for Lund­beck to prove it's worth $2B

They may be late, but Lundbeck is now officially in the game for preventing migraine with CGRP drugs.

The FDA has OK’d eptinezumab, the prize in Lundbeck’s $2 billion acquisition of Alder. Like rival offerings from Amgen/Novartis, Eli Lilly and Teva, the antibody blocks the calcitonin gene-related peptide, which is believed to dilate blood vessels in the brain and cause pain.

It will now be sold as Vyepti. The company has yet to announce a price. Amgen and Novartis had set the wholesale acquisition cost of their pioneering Aimovig at $6,900 for a year’s supply before raising it slightly this year; Lilly and Teva had followed suit with Emgality and Ajovy.

Tal Zaks (Moderna via YouTube)

For two decades, a new vac­cine tech­nol­o­gy has been slow­ly ap­proach­ing prime time. Now, can it stop a pan­dem­ic?

Two months before the outbreak, Moderna CMO Tal Zaks traveled from Cambridge, MA to Washington DC to meet with Anthony Fauci and the leaders of the National Institutes of Health.

For two years, Moderna had worked closely with NIH researchers to build a new kind of vaccine for MERS, one of the deadliest new viruses to emerge in the 21st century. The program was one test for a new technology designed to be faster, cheaper and more precise than the ways vaccines had been made for over a century. They had gathered evidence the technology could work in principle, and Fauci, the longtime head of the National Institute of Allergy and Infectious Diseases and a longtime advocate for better epidemic preparedness, wanted to see if it, along with a couple of other approaches, could work in a worst-case scenario: A pandemic.

“[We were] trying to find a test case for how to demonstrate if our technology could rapidly prepare,” Zaks told Endpoints News.

Zaks and Fauci, of course, wouldn’t have to wait to develop a new test. By year’s end, an outbreak in China would short circuit the need for one and throw them into 24/7 work on a real-world emergency. They also weren’t the only ones with new technology who saw a chance to help in a crisis.

An ocean away, Lidia Oostvogels was still on vacation and relaxing at her mother’s house in Belgium when her Facebook started changing. It was days after Christmas and on most people’s feeds, the news that China had reported a novel virus to the World Health Organization blurred into the stream of holiday sweaters and fir trees. But on Oostvogels’s feed, full of vaccine researchers and virus experts, speculation boiled: There was a virus in China, something contained to the country, but “exotic,” “weird,” and maybe having to do with animals. Maybe a coronavirus.

Lidia Oostvogels

“I was immediately thinking like, ‘Hey, this is something that if needed, we can play a role,'” Oostvogels told Endpoints.

Christos Kyratsous (via LinkedIn)

He built a MERS treat­ment in 6 months and then the best Ebo­la drug. Now Chris­tos Kyrat­sous turns his sights on Covid-19

TARRYTOWN, NY — In 2015, as the Ebola epidemic raged through swaths of West Africa, Kristen Pascal’s roommates sat her down on their couch and staged an intervention.

“Are you sure this is what you want to be doing with your life?” she recalls them asking her.

Special report

Pascal, a research associate for Regeneron, had been coming home at 2 am and leaving at 6 am. At one point, she didn’t see her roommate for a week. For months, that was life in Christos Kyratsous’ lab as the pair led a company-wide race to develop the first drug that could effectively treat Ebola before the outbreak ended. For Pascal, that was worth it.

“I’m ok, I don’t have Ebola,” Pascal told them. “I see that death toll rising and I can’t not do something about it.”

Last August, Regeneron learned they had succeeded: In a large trial across West Africa, their drug, REGN-EB3, was vastly more effective than the standard treatments. It was surprise news for the company, coming just 10 months into a trial they thought would take several years and a major victory in the global fight against a deadly virus that killed over 2,000 in 2019 and can carry a mortality rate of up to 90%.

For Kyratsous and Pascal, though, it brought only fleeting reprieve. Just four months after the NIH informed them REGN-EB3 worked, Kyratsous was back in his office reading the New York Times for updates on a new outbreak on another continent, and wondering alongside Pascal and senior management whether it was time to pull the trigger again.

In late January, as the death toll swelled and the first confirmed cases outside China broke double digits, they made a decision. Soon they were back on the phone with the multiple government agencies and their coronavirus partners at the University of Maryland’s Level 3 bio lab. The question was simple: Can Kyratsous and his team use a process honed over two previous outbreaks, and create a treatment before the newest epidemic ends? Or worse, if, as world health experts fear, it doesn’t vanish but becomes a recurrent virus like the flu?

“Christos likes things immediately,” Matt Frieman, Regeneron’s coronavirus collaborator at the University of Maryland, told Endpoints. “That’s what makes us good collaborators: We push each other to develop things faster and faster.”

The first time Regeneron tried to respond to a global outbreak, it was something of a systems test, Kyratsous explains from his office at Regeneron’s Tarrytown headquarters. Kyratsous, newly promoted, has crammed it with photos of his family, sketches of viral vectors and a shark he drew for his 3-year-old son. He speaks rapidly – an idiosyncrasy his press person says has only been aggravated this afternoon by the contents of his “Regeneron Infectious Diseases”-minted espresso glass – and he gesticulates with similar fluidity, tumbling through antibodies, MERS, the novel coronavirus, Ebola-infected monkeys.

Es­pe­ri­on's goldilocks cho­les­terol fight­er wins FDA ap­proval — will its 'tra­di­tion­al' pric­ing ap­proach spur adop­tion?

It’s more effective than decades-old statins but not as good as the injectable PCSK9 — the goldilocks treatment for cholesterol-lowering, bempedoic acid, has secured FDA approval.

Its maker, Esperion Therapeutics, is betting that their pricing strategy — a planned list price of between $10 to $11 a day — will help it skirt the pushback the PCSK9 cholesterol fighters, Repatha and Praluent, got from payers for their high sticker prices.

The sky-high expectations for the pair of PCSK9 drugs that were first approved in 2015 quickly simmered — and despite a 60% price cut, coupled with data showing the therapies also significantly cut cardiovascular risk, sales have not really perked up.

Esperion is convinced that by virtue of being a cheaper oral therapy, bempedoic acid will hit that sweet spot in terms of adoption.

“We’re kind of like the old comfortable shoe,” Esperion’s chief commercial officer Mark Glickman remarked in an interview with Endpoints News ahead of the decision date. “It’s an oral product, once-daily and nontitratable — these are things that just resonate so true with patients and physicians and I think we’ve kind of forgotten about that.”

UP­DAT­ED: A space odyssey for new an­tibi­otics: MIT's ma­chine learn­ing ap­proach

Drug development is complex, expensive and comes with lousy odds of success — but in most cases, if you make it across the finish line brandishing a product with an edge (and play your cards right) it can be a lucrative endeavor.

As it stands, the antibiotic market is cursed — it harbors the stink of multiple bankruptcies, a dearth of innovation, and is consequently barely whetting the voracious appetites of big pharma or venture capitalists. Enter artificial intelligence — the biopharma industry’s cure-all for the pesky process of making a therapeutic, including data mining, drug discovery, optimal drug delivery, and addressable patient population.

Gilead los­es two more patent chal­lenges on HIV pill, set­ting up court­room fight in Delaware

Gilead sustained two more losses in their efforts to rid themselves of an activist-backed patent lawsuit from the US government over a best-selling HIV pill.

Urged on by activists seeking to divert a portion of Gilead’s revenue to clinics and prevention programs, the Department of Health and Human Services made a claim to some of the patents for the best-selling HIV prevention drug, Truvada, also known as PrEP. Gilead responded by arguing in court that HHS’s patents were invalid.

Today, the US Patent and Trademark Office ruled that Gilead was likely to lose the last two of those challenges as well. The USPTO ruled against Gilead on the first two patents earlier this month.
