FDA pan­el of­fers a wa­ver­ing thumbs up for Eli Lil­ly's 2 mg baric­i­tinib, thumbs down on 4 mg

A large pan­el of out­side rheuma­toid arthri­tis ex­perts gath­ered at the FDA to dis­cuss Eli Lil­ly’s $LLY con­tro­ver­sial re-ap­pli­ca­tion for an ap­proval of baric­i­tinib, vot­ing in lop­sided fa­vor of the ef­fi­ca­cy and safe­ty of the 2 mg dose of the rheuma­toid arthri­tis drug, but turned their thumbs down on the 4 mg dose.

Ten vot­ed in fa­vor of the risk/ben­e­fit bal­ance of the 2 mg dose, 5 against. The num­bers were re­versed for the 4 mg, falling 10 against and 5 in fa­vor.

These ex­pert votes hinged on a con­sid­er­able amount of con­fu­sion and un­cer­tain­ty, though, which sev­er­al mem­bers were quick to ac­knowl­edge.

Said one mem­ber who vot­ed yes on the ad­e­qua­cy of the safe­ty da­ta of the 2 mg dose: “This whole thing is a house of cards and I could have gone ei­ther way.”

An­oth­er: ”My best guess is yes.”

Er­i­ca Brit­tain: “I vot­ed yes, I could have def­i­nite­ly vot­ed no.”

“We still don’t have enough da­ta,” said one mem­ber who vot­ed in fa­vor of the ad­e­qua­cy of the 2 mg dose.

“I would urge the spon­sor to get as much da­ta as pos­si­ble on the safe­ty side,” com­ment­ed com­mit­tee chair Jose Sch­er, who vot­ed against both the 2 mg and 4 mg dos­es based on in­ad­e­quate safe­ty da­ta.

That all could emerge as a ma­jor headache for Eli Lil­ly and its part­ners at In­cyte $IN­CY, as the com­pa­ny wants to start treat­ment-re­sis­tant pa­tients at 4 mg and then ta­per down to 2 mg if they sta­bi­lize their dis­ease.

Lil­ly’s shares ini­tial­ly dropped 3% in ear­ly trad­ing Tues­day, then man­aged to climb back up in­to the green, bare­ly. In­cyte shares, though, are still down 5% in mid-morn­ing trad­ing.

The pan­el dis­cus­sion in­clud­ed a me­an­der­ing se­ries of com­ments, with some voic­es sup­port­ing an ap­proval to of­fer a new op­tion for pa­tients and a few flag­ging some se­ri­ous safe­ty is­sues and oth­ers un­cer­tain just what was demon­strat­ed by the da­ta on dis­play.

On one point, the ad­vi­so­ry com­mit­tee found clear con­sen­sus around ef­fi­ca­cy. By a vote of 14 to 1 they con­clud­ed that there was clear ev­i­dence of the “sub­stan­tial ev­i­dence” that backed the drug’s ef­fi­ca­cy, with a unan­i­mous vote in fa­vor of ef­fi­ca­cy as a sec­ond-line ther­a­py af­ter pa­tients had failed on their front­line drug.

Much of the dis­cus­sion, though, cen­tered on the safe­ty of the drug, where reg­u­la­tors raised some of their most se­ri­ous ob­jec­tions to the drug, with a star­tling sig­nal on throm­boem­bolism.

One com­mit­tee mem­ber not­ed a dis­cus­sion con­cern­ing whether rheuma­tol­o­gists are used to look­ing for and mon­i­tor­ing for ad­verse events. But, he added, “rheuma­tol­o­gists do not typ­i­cal­ly look for throm­boem­bol­ic events, that’s not on the list of things that are tra­di­tion­al­ly watched for.”

There was a con­sid­er­able dis­cus­sion whether the com­mit­tee had the da­ta need­ed to make a con­clu­sion on the drug’s safe­ty, par­tic­u­lar­ly when it came to the 2 mg dose. 

“None of these stud­ies are pow­ered to look for rare events,” said Sch­er, high­light­ing stud­ies that weren’t pow­ered to de­ter­mine the risk of throm­boem­bolisms, or blood clots, and not­ing that there was con­sid­er­able con­fu­sion about the da­ta and the con­clu­sions that could be drawn from them — par­tic­u­lar­ly re­lat­ing to the 2 mg dose, where the da­ta were lack­ing.

Baric­i­tinib is a re­mark­able test case for the FDA. Re­ject­ed in 2017 in a stun­ning set­back for a drug that had been billed as a block­buster in the mak­ing, the agency re­versed course and al­lowed Lil­ly to re­file for an ap­proval as a sec­ond-line ther­a­py with­out the added da­ta that had been in­sist­ed on. The agency’s re­view makes clear that while Eli Lil­ly in­ves­ti­ga­tors pro­vid­ed more in­for­ma­tion, none of it ad­dressed their core con­cerns, es­pe­cial­ly re­gard­ing a high­er rate of throm­bo­sis that ap­peared for the first time in the field.

FDA re­view­ers dis­agreed on the da­ta of­fered for the 2 mg and 4 mg dos­es, with some will­ing to wave it through and oth­ers not­ing that the study da­ta for the 2 mg nev­er pro­vid­ed suf­fi­cient in­for­ma­tion for a de­ci­sion on safe­ty and ef­fi­ca­cy. There was al­so no con­sis­tent da­ta to back up the 4 mg dose over the 2 mg dose, ac­cord­ing to reg­u­la­tors. 

Even if it gets an ap­proval now, Lil­ly is go­ing to have an up­hill fight against Pfiz­er’s Xel­janz (to­fac­i­tinib), the first JAK in­hibitor to make it to the mar­ket — with­out the harsh FDA crit­i­cism or is­sues with throm­bo­sis that promise to cap­size Lil­ly’s launch.

Why of­fer an ap­proval now if there are oth­er drugs on the mar­ket that could do as well or bet­ter? And if it is ap­proved, will this drug be re­served for last-chance op­por­tu­ni­ties?

“We know we didn’t make your lives any eas­i­er,” said Sch­er as he turned at the end to the FDA’s rep­re­sen­ta­tives.

Trump’s HHS claims ab­solute au­thor­i­ty over the FDA, clear­ing path to a vac­cine EUA

The top career staff at the FDA has vowed not to let politics overrule science when looking at vaccine data this fall. But Alex Azar, who happens to be their boss’s boss, apparently won’t even give them a chance to stand in the way.

In a new memorandum issued Tuesday last week, the HHS chief stripped the FDA and other health agencies under his purview of their rule making ability, asserting all such power “is reserved to the Secretary.” Sheila Kaplan of the New York Times first obtained and reported the details of the September 15 bulletin.

Un­der fire, FDA to is­sue stricter guid­ance for Covid-19 vac­cine EUA this week — re­port

The FDA has been insisting for months that a Covid-19 vaccine had to be at least 50% effective – a measure of transparency meant to shore public trust in the agency and in a vaccine that had been brought forward at record speed and record political pressure. But now, with concerns of a Trump-driven authorization arriving before the election, the agency may be raising the bar.

The FDA is set to release new guidance that would raise safety and efficacy requirements for a vaccine EUA above earlier guidance and above the criteria used for convalescent plasma or hydroxychloroquine, The Washington Post reported. Experts say this significantly lowers the odds of an approval before the election on November 3, which Trump has promised despite vocal concerns from public health officials, and could help shore up public trust in the agency and any eventual vaccine.

PhII Alzheimer's fail­ure deals new blow to Roche, AC Im­mune — but the tau hy­poth­e­sis is far from dead

The leading anti-tau antibody has failed its first Phase II testing, casting a shadow on a popular target (just trailing amyloid beta) for Alzheimer’s disease.

Roche and AC Immune are quick to acknowledge disappointment in the topline readout, which suggested that semorinemab did not reduce cognitive decline among patients with early Alzheimer’s disease, who are either just starting to have symptoms or have mild manifestations.

News brief­ing: PureTech plans Nas­daq de­but with sec­ondary list­ing; GoodRx prices $725M IPO

London Stock Exchange-listed PureTech Health announced Wednesday that it’s looking to extend to Nasdaq. But due to its “strong cash position,” the biotech says it isn’t issuing any new shares in the potential secondary listing.

The company’s shares closed at £256.50 Tuesday on the London Stock Exchange. Its candidate LYT-100 is currently in Phase I development for various indications, including lymphatic flow disorders and fibrotic and inflammatory disorders. PureTech is expecting a Phase Ib readout in lymphatic flow disorders later this year, and is also planning to launch a Phase II study for the drug to treat respiratory conditions experienced after Covid-19.

Covid-19 roundup: J&J be­gins piv­otal Phase III tri­al for vac­cine; Con­tro­ver­sial hu­man chal­lenge tri­als to be­gin in Lon­don — re­port

Johnson & Johnson announced it’s beginning a pivotal Phase III trial for its Covid-19 candidate, JNJ-78436735 — the first single-dose vaccine in this stage.

The Phase III trial, dubbed ENSEMBLE, will enroll 60,000 patients worldwide, making it the largest Phase III study of a Covid-19 vaccine to date. J&J said the candidate achieved positive interim results in a Phase I/IIa study, which will be published “imminently.” There’s a possibility that the first batches will be ready for potential emergency use in early 2021, according to the biotech.

The mi­cro-cap that tapped a mask-skep­tic con­gress­man for their Covid DSMB is ap­ply­ing for an EUA. Their ev­i­dence? 21 pa­tients

NeuroRx, the tiny biotech that came under fire last week after Politico reported they selected a congressman and two other acquaintances of the CEO to supervise their Covid-19 drug trial, announced today that they will ask the FDA to authorize their drug based on the results of just 21 patients.

Such an application would test the agency’s standards of evidence for an EUA, which have already come under scrutiny after controversial authorizations for convalescent plasma and hydroxychloroquine. The only other company to discuss their intention to file for an EUA, Eli Lilly, did so after results came back from a randomized control study testing their antibody in over 450 patients.

J&J re­leas­es PhI­II safe­ty blue­print for Covid-19 vac­cine tri­al. How does it stack up to Mod­er­na, Pfiz­er and As­traZeneca?

Along with the initiation of its Phase III Covid-19 vaccine study announced Wednesday morning, Johnson & Johnson also released its trial protocol, giving an inside look at how the company is conducting its late-stage research.

The move comes after the other three companies conducting Phase III’s in the US — Moderna, Pfizer and AstraZeneca — each disclosed their own trial blueprints within the last week. Though the release of such protocols is typically done after trials have been completed, drug developers had come under intense pressure after a brief safety scare in an AstraZeneca trial and amid growing concern of a politically motivated vaccine authorization.

UP­DAT­ED: Still held down by clin­i­cal hold, No­var­tis' Zol­gens­ma falls fur­ther be­hind Bio­gen and Roche as FDA asks for a new piv­otal study

Last October, the FDA slowed down Novartis’ quest to extend its gene therapy to older spinal muscular atrophy patients by slapping a partial hold on intrathecal administration. Almost a year later, the hold is still there, and regulators are adding another hurdle required for regulatory submission: a new pivotal confirmatory study.

The new requirement — which departs significantly from Novartis’ prior expectations — will likely stretch the path to registration beyond 2021, when analysts were expecting a BLA submission. That could mean more time for Biogen to reap Spinraza revenues and Roche to ramp up sales of Evrysdi in the absence of a rival.
