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.

2023 Spot­light on the Fu­ture of Drug De­vel­op­ment for Small and Mid-Sized Biotechs

In the context of today’s global economic environment, there is an increasing need to work smarter, faster and leaner across all facets of the life sciences industry.  This is particularly true for small and mid-sized biotech companies, many of which are facing declining valuations and competing for increasingly limited funding to propel their science forward.  It is important to recognize that within this framework, many of these smaller companies already find themselves resource-challenged to design and manage clinical studies themselves because they don’t have large teams or in-house experts in navigating the various aspects of the drug development journey. This can be particularly challenging for the most complex and difficult to treat diseases where no previous pathway exists and patients are urgently awaiting breakthroughs.

Eisai and METAvivor plan to debut the latest 'This is MBC' campaign at the San Antonio Breast Cancer Symposium (SABCS).

Ei­sai re-ups metasta­t­ic breast can­cer aware­ness cam­paign with strik­ing pa­tient pho­tographs

Eisai is debuting the newest ads in its long-running “This is MBC” campaign this week. In what’s become an annual tradition, Eisai and metastatic breast cancer advocacy partner METAvivor will show the striking photographs of people living with metastatic breast cancer first at the San Antonio Breast Cancer Symposium (SABCS).

The new “Imagine” campaign features 12 patients photographed around waterfalls to symbolize that same kind of sudden drop into a pool that MBC causes in a person’s life, said Beth Fairchild, co-founder of #CancerCulture who was the president of METAvivor six years ago when the campaign began. Fairchild, who is living with MBC, has helped create all of the annual “This is MBC” campaigns.

Pfiz­er and BioN­Tech look to toss Mod­er­na patent suit, call­ing claims 'unen­force­able'

Pfizer and BioNTech took a swing at Moderna’s Covid-19 patent claims in Massachusetts federal court on Monday, calling them “invalid,” “overbroad” and “unenforceable.”

The defendants also filed counterclaims against the Cambridge, MA-based biotech, seeking a dismissal of the case, recovery of court fees and an official judgment invalidating Moderna’s claims.

Moderna sued Pfizer and BioNTech back in August, alleging that the partners’ Covid-19 vaccine Comirnaty copied parts of Moderna’s vaccine technology patented before the pandemic, when it was developing an mRNA vaccine for MERS, another respiratory illness.

Glen­mark hit with warn­ing let­ter over pro­ce­dures, qual­i­ty con­trol is­sues at In­dia man­u­fac­tur­ing plant

The generics producer Glenmark Pharmaceuticals has been handed a warning letter by US regulators.

The letter, which was sent to the manufacturer on Nov. 22, noted issues from an inspection over the summer at Glenmark’s facility in the town of Colvale, India, in the state of Goa.

According to the letter, the FDA found that Glenmark’s investigation of rejected batches of drugs “failed to extend to other batches, dosage strengths, and drug products.” The warning letter also noted that the site had failed to establish “adequate written procedures” for production and process control to ensure drugs have the correct strength, quality and purity.

Klick Health is lighting the way, literally, this holiday season to encourage connection for lonely seniors in long-term care facilities.

Eu­ro­pean Com­mis­sion lays ground­work to un­wind Il­lu­mi­na's $7B+ Grail merg­er

The European Commission has recommended steps that — though not yet final — would require Illumina to “swiftly” unwind its controversial $7.1 billion Grail buyout.

The Commission delivered a “statement of objections” on Monday, detailing the process Illumina would need to take in divesting Grail, its blood testing spinout launched in 2016. Illumina re-acquired Grail back in August, despite criticism from both the FTC and EU.

Gos­samer’s Fa­heem Has­nain de­fends a round of pos­i­tive PAH da­ta as a clear win. But can these PhII re­sults stand up to scruti­ny?

Gossamer Bio $GOSS posted a statistically significant improvement for its primary endpoint in the key Phase II TORREY trial for lead drug seralutinib on Tuesday morning. But CEO Faheem Hasnain has some explaining to do on the important secondary of the crucial six-minute walk distance test — which will be the primary endpoint in Phase III — as the data on both endpoints fell short of expectations, missing one analyst’s bar on even modest success.
