Back­lash: Har­vard ex­perts fret over the fall­out from FDA’s OK for Sarep­ta’s con­tro­ver­sial Duchenne drug

Two of Har­vard’s top FDA pol­i­cy ex­perts, Aaron Kessel­heim and Jer­ry Avorn, have ex­pressed some deep con­cerns about the agency’s ap­proval of eteplirsen, OK’d to be sold as Ex­ondys 51 for $300,000-plus a year, and the im­pli­ca­tions for fur­ther show­downs in the near fu­ture as more de­vel­op­ers look to test the bound­aries on the agency’s stan­dards.

Writ­ing on­line in the Jour­nal of the Amer­i­can Med­ical As­so­ci­a­tion, the two re­viewed the cam­paign used to back eteplirsen, win­ning an OK with scant ev­i­dence of suc­cess in pro­duc­ing dy­s­trophin — con­trary to what Sarep­ta had claimed — a prob­lem­at­ic re­liance on his­tor­i­cal com­par­isons, and the unan­i­mous op­po­si­tion of the main re­view­ers, in­clud­ing se­nior of­fi­cials who ap­pealed Janet Wood­cock’s lone in­sis­tence on an ac­cel­er­at­ed ap­proval.

They didn’t see much mer­it in Sarep­ta’s case, and more of these con­fronta­tions are like­ly on the way now, they note. The two pol­i­cy ex­perts al­so con­clud­ed that the ap­proval threat­ens pa­tients and oth­er com­pa­nies that stuck with FDA guide­lines re­quir­ing much more rig­or­ous da­ta. They wrote:

Speed­ing drugs to mar­ket based on such bio­mark­er out­comes can ac­tu­al­ly lead to a worse out­come for pa­tients, even those with life-threat­en­ing dis­eases, if a prod­uct con­fers no mean­ing­ful ben­e­fit and car­ries a risk of ad­verse ef­fects and a high cost. Im­me­di­ate­ly af­ter ap­proval, the man­u­fac­tur­er an­nounced a price of $300,000 per year for eteplirsen. This ap­proach al­so un­fair­ly pe­nal­izes man­u­fac­tur­ers that pur­sue a more rig­or­ous course of de­vel­op­ment us­ing more clin­i­cal­ly rel­e­vant end points, while re­ward­ing com­peti­tors that sub­mit tri­als that have less ev­i­dence sup­port­ing ef­fi­ca­cy.

The ex­perts al­so raised fur­ther con­cerns about a drug that re­lied on a ve­he­ment cam­paign by pa­tient ad­vo­cates and the way in which the reg­u­la­tor should ap­proach the anec­do­tal sup­port pro­vid­ed by pa­tients and their fam­i­lies in tiny, un­con­trolled stud­ies.

Echo­ing re­marks from NYU’s Art Ca­plan, who re­cent­ly out­lined his thoughts in an in­ter­view with me, Kessel­heim and Avorn are al­so look­ing for a new ap­proach that can pro­vide a bet­ter frame­work for more such ap­provals, in­clud­ing pro­grams that of­fer these drugs at cost, rather than with a big prof­it built in.

Pa­tients with DMD need bet­ter treat­ments, and drugs like eteplirsen might one day fill that role. For now, though, the drug has pro­vid­ed a wor­ri­some mod­el for the next gen­er­a­tion of mol­e­c­u­lar­ly tar­get­ed ther­a­pies: demon­strate a slight dif­fer­ence in a lab­o­ra­to­ry test, ac­ti­vate the pa­tient com­mu­ni­ty, win ap­proval, and charge high prices, while re­ly­ing on lim­it­ed reg­u­la­to­ry fol­low-up.

The FDA’s John Jenk­ins re­cent­ly out­lined just why the FDA needs to stick with rig­or­ous de­vel­op­ment re­quire­ments, not­ing that Sarep­ta’s cam­paign was “NOT” a good mod­el for oth­ers to fol­low. But what Kessel­heim, Avorn and Ca­plan are say­ing is that the dis­cus­sion about the fall­out from the Sarep­ta de­ci­sion is just be­gin­ning, no mat­ter how much top reg­u­la­tors would like to put it be­hind the agency.

Keep­ing pres­sure on Am­gen, Mi­rati draws mixed re­views on lat­est cut of KRAS da­ta

As the close runner-up to Amgen’s Lumakras in the KRAS race, any data cut from Mirati’s adagrasib continues to draw scrutiny from analysts. And the latest batch of numbers from ASCO is a decidedly mixed bag.

While a quick comparison suggests that adagrasib spurred slightly more responses and led to a longer overall survival than Lumakras among a group of non-small cell lung cancer patients, its duration of response appears shorter and the safety profile continues to spark concern.

Tran­si­tion to new Eu­ro­pean clin­i­cal tri­als in­fo sys­tem starts slow­ly

At the end of January, the European Medicines Agency officially launched its new clinical trials info system (CTIS), although the migration to the new platform has only really just begun, and sponsors have until the end of January 2023 before all initial trial applications must be submitted through CTIS.

Overall, 56 clinical trial applications have been submitted in CTIS during the first 3 months since the launch of the system on Jan. 31, according to new data posted by the EMA. By comparison, about 4,000 new trials are authorized each year across Europe.

Ann is one of ViiV Healthcare's newest spokespeople as the retired school administrator speaks up about her HIV status.

GSK's Vi­iV de­buts next evo­lu­tion in HIV med Dova­to cam­paign with new spokes­peo­ple and new mes­sage

When Ann saw the first TV commercials for HIV medicine Dovato, she didn’t see herself represented. So the 74-year-old retired school administrator who’s been living with HIV since 1998, reached out to GSK’s ViiV Healthcare and asked why not?

Now Ann is one of three people starring in ViiV’s latest Dovato campaign called “Detect This.” The next-step evolution in the branded campaign plays on the word “detect” — often used in describing HIV status under control as undetectable — but in this case, uses the word as a directive for people to understand they can use fewer medicines.

Switzer­land to de­stroy over 600,000 ex­pired dos­es of Mod­er­na Covid vac­cine

As concerns related to uptake and distribution continue to linger, Switzerland is among the first countries that plans to destroy hundreds of thousands of expired and unused Covid-19 vaccine doses.

The European country said it plans to destroy more than 600,000 doses of Moderna’s Spikevax Covid-19 vaccine as the doses have reached their expiration date.

However, Moderna CEO Stéphane Bancel told the World Economic Forum in Davos, Switzerland that he’s in the process of throwing 30 million doses in the garbage, exclaiming, “We have a big demand problem.”

AS­CO ab­stracts mint some ear­ly win­ners, but Io­vance, Spring­Works get hit by mas­sive loss­es

Before cancer-focused biotechs start their trek to the first in-person American Society of Clinical Oncology (ASCO) annual conference since the pandemic began, investors have taken a good look at the teasers for the data scheduled to be presented — and started placing bets.

With its power to confer overnight fame, ASCO is a stage where impressive or surprise debut performances can go a long way. On the other hand, disappointing details could be punishing.

Nassim Usman, Catalyst Biosciences CEO

Af­ter $60M Ver­tex deal, group of Cat­a­lyst share­hold­ers claims biotech could’ve sold as­sets three years ago

Catalyst Biosciences was down to five employees in March, and the biotech needed to do something after two rounds of layoffs, a nixed collaboration and a culling of its hemophilia program.

In came Vertex, with $60 million to buy up the South San Francisco biotech’s preclinical complement drugs, which target the system that bridges the body’s innate and adaptive immune response and a class most known for Ultomiris and Soliris. The deal includes CB 2782-PEG, the dry AMD drug that Biogen no longer wanted in March.

Roche's CD20xCD3 does­n't beat Gen­mab at ORR, but sets bar for CR da­ta on lym­phoma drug

On its way to potentially becoming the first to market with a CD20xCD3 bispecific for aggressive lymphoma, Big Pharma’s largest R&D spender has some more data to pad its case with an FDA filing slated for later this year.

Roche dropped some more details from a Phase II expansion study of its fixed-duration glofitamab, to be presented at next week’s ASCO annual meeting, in patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL). The patients had received a median of three prior therapies.

Pile-on over PBMs con­tin­ues with FTC com­ments and a new bi­par­ti­san Sen­ate bill

More than 500 stakeholders sent comments to the FTC on whether the commission should look further into pharma middlemen, known as PBMs, with many of the commenters calling for more federal oversight.

Similar to the critical open comment period in a deadlocked FTC session last February, pharmacies and pharmacy groups are continuing to call out the lack of transparency among the top 3 PBMs, which control about 80% of the market.
