Weeks ago, the FDA en­dorsed a Lam­bert-Eaton myas­thenic syn­drome (LEMS) drug from fam­i­ly-run New Jer­sey-based com­pa­ny called Ja­cobus Phar­ma­ceu­ti­cals in pe­di­atric pa­tients, on the ba­sis of adult da­ta, to the sur­prise of Cat­a­lyst Phar­ma­ceu­ti­cals which on­ly last year got its pricey — yet sim­i­lar — treat­ment for the rare au­toim­mune dis­or­der across the fin­ish line in adults. It has now been re­vealed that Ja­cobus’ ver­sion car­ries a price that is less than half of Cat­a­lyst’s Fir­dapse — a move that could fu­el off-la­bel pre­scrip­tion in adults.

Be­fore Cat­a­lyst’s Fir­dapse was sanc­tioned for use by the FDA, hun­dreds of pa­tients had been able to ac­cess a sim­i­lar drug from com­pound­ing phar­ma­cies for a frac­tion of the cost, or Ja­cobus’ for free, as part of an FDA-rat­i­fied com­pas­sion­ate use pro­gram. But the ap­proval of the Cat­a­lyst drug, ac­com­pa­nied by mar­ket ex­clu­siv­i­ty span­ning sev­en years — ef­fec­tive­ly pre­clud­ed Ja­cobus and com­pound­ing phar­ma­cies from sell­ing their ver­sions.

Dos­ing for any of these treat­ments is based on the pa­tient’s weight and dis­ease sever­i­ty. Cat­a­lyst’s Fir­dapse, which is ap­proved with a max­i­mum dose of 80 mg, car­ries an av­er­age list price of $375,000 a year. The com­pa­ny does not dis­close a per pill num­ber, a Cat­a­lyst spokesper­son told End­points News. 

The list price for Ruzur­gi is $80 for each 10 mg tablet, and Ja­cobus’ treat­ment is ap­proved up to a max­i­mum dose of 100 mg, Lau­ra Ja­cobus, who runs the pri­vate­ly-held com­pa­ny, told End­points News. “As an ex­am­ple, the whole­sale cost for a 60 mg dos­ing reg­i­men would be $175,200.00 an­nu­al­ly.  The cost to sup­port a pa­tient re­quir­ing a dai­ly dose of 100 mg would be $292,000.00 an­nu­al­ly.”

Ver­mont Sen­a­tor Bernie Sanders — ahead of his an­nounce­ment to make a sec­ond at­tempt at the pres­i­den­cy — spot­light­ed Cat­a­lyst for the “im­moral ex­ploita­tion of pa­tients”. Oth­er crit­ics of Cat­a­lyst’s pric­ing strat­e­gy sug­gest­ed that de­pend­ing on how Ja­cobus prices its drug, Ruzur­gi, in­sur­ers could be per­suad­ed to fa­vor it over Cat­a­lyst’s prod­uct de­spite be­ing of­fi­cial­ly ap­proved for pe­di­atric use on­ly. As far as the FDA is con­cerned, doc­tors can pre­scribe drugs for off-la­bel use when they judge that it is med­ical­ly ap­pro­pri­ate for their pa­tient.

Fir­dapse land­ed on the US mar­ket this Jan­u­ary, and Cat­a­lyst has not­ed it has en­coun­tered min­i­mal push­back from pay­ers, and in­di­cat­ed that typ­i­cal­ly, cov­ered pa­tients pay less than $10 per month out-of-pock­et.

In a note pub­lished last month, Sun­Trust Robin­son Humphrey’s Ed­ward Nash sug­gest­ed that de­spite sug­ges­tions to the con­trary, “(W)e have not seen any prece­dent where pay­ers cov­er an off-la­bel drug for use in un­ap­proved pa­tient pop­u­la­tion”.

Mean­while, HC Wain­wright’s An­drew Fein sug­gest­ed that Ja­cobus, de­spite the rep­u­ta­tion of a “mod­ern-day Robin Hood” is not equipped with the in­fra­struc­ture nor the ex­pe­ri­ence to sup­port a com­mer­cial push of Ruzur­gi, even with the ap­proval in hand.

“Hand­i­capped by le­gal rea­sons, we do not be­lieve that Ja­cobus can open­ly pro­mote off-la­bel use in LEMS adults…It is un­clear if and how Ja­cobus would be able to ex­pand com­mer­cial pen­e­tra­tion oth­er than through pro­mot­ing a pro­lif­er­a­tion of off-la­bel use at aca­d­e­m­ic cen­ters that were en­rolled in the com­pas­sion­ate pro­gram (which mounts to ap­prox­i­mate­ly 200 pa­tients),” he wrote in a May note.

In LEMS pa­tients, the body’s own im­mune sys­tem launch­es an at­tack on the neu­ro­mus­cu­lar junc­tion — which con­nects nerves and mus­cles. The con­di­tion can as­so­ci­at­ed with oth­er au­toim­mune dis­eases, but tends to oc­curs in pa­tients with can­cer. Its preva­lence in pe­di­atric pa­tients is not known, but glob­al­ly it is es­ti­mat­ed to af­fect three per mil­lion in­di­vid­u­als, ac­cord­ing to the FDA. In a re­cent in­vestor pre­sen­ta­tion Cat­a­lyst sug­gest­ed there are 3,000 LEMS US pa­tients, of which 300 are on Fir­dapse.

A STAT re­port pub­lished on Mon­day sug­gest­ed that some adult LEMS pa­tients have in­sin­u­at­ed that Fir­dapse is not ef­fec­tive enough and more tablets be­yond the ap­proved 80 mg dose must be tak­en for re­lief — these ex­tra pills sad­dle them with out-of-pock­et bills that could climb to thou­sands of dol­lars month­ly. The Cat­a­lyst spokesper­son did not pro­vide com­ment on this as­ser­tion.

SpringWorks and Satsuma — both biotech spinouts that have closed B rounds in April — are loading up with IPO cash to boost their respective late-stage plans.
SpringWorks

Bain-backed SpringWorks is the better-known company of the two, and it’s gunning for a larger windfall of $115 million to add to $228 million from previous financings. In the process, the Stamford, CT-based team is also drawing the curtains on the partnerships it has in mind for the pair of assets it had initially licensed from Pfizer.

Data reveal that different racial and ethnic groups — by nature and/or nurture — can respond differently in terms of pharmacokinetics, efficacy, or safety to therapeutics, but this disparity is not necessarily accounted for in clinical trials. A fresh analysis of the last decade of US cancer drug approvals suggests the trend continues, cementing previous research that suggests oncology trials are woefully under-representative of the racial makeup of the real world.

Back in the spring of last year, Vanda Pharmaceuticals $VNDA served up a hot stew of mixed data for a slate of endpoints related to what they called clear evidence that their melatonin sleep drug Hetlioz (tasimelteon) could help millions of travelers suffering from jet lag.

Never mind that they couldn’t get a planned 90 people in the study, settling for 25 instead; Vanda CEO Mihael H. Polymeropoulos said they were building on a body of data to prove it would help jet-lagged patients looking for added sleep benefits. And that, they added, would be worth a major upgrade from the agency as they sought to tackle a big market.

Earlier this year, an executive from Juvenescence-backed AgeX predicted the field of longevity will eventually “dwarf the dotcom boom.” Greg Bailey, the UK-based anti-aging biotech’s CEO, certainly hopes so.

On Monday, Juvenescence completed its $100 million Series B round of financing. The company is backed by British billionaire Jim Mellon — who wrote his 400-page guide to investing in the field of longevity shortly after launching the company in 2017. Bailey, who served as a board director for seven years at Medivation before Pfizer swallowed the biotech for $14 billion, is joined by Declan Doogan, an industry veteran with stints at Pfizer $PFE and Amarin $AMRN.

Another big drug approval came through on Friday afternoon as the FDA OK’d AbbVie’s upadacitinib — an oral JAK1 inhibitor that is hitting the rheumatoid arthritis market with a black box warning of serious malignancies, infections and thrombosis reflecting fears associated with the class.

It will be sold as Rinvoq — at a wholesale price of $59,000 a year — and will likely soon face competition from a drug that AbbVie once controlled, and spurned. Reuters reports that a 4-week supply of Humira, by comparison, is $5,174, adding up to about $67,000 a year.
