Abun­dant fund­ing, sparse da­ta: San Fran­cis­co start­up backs 're­al world' mod­el for rare dis­ease drug de­vel­op­ment

Rare dis­eases, a field of drug de­vel­op­ment where fund­ing far out­strips re­search on of­ten poor­ly un­der­stood con­di­tions, can leave sci­en­tists of­ten rein­vent­ing the wheel to en­gi­neer ther­a­peu­tics.

RD­MD, a San Fran­cis­co-based com­pa­ny, has a plan to ad­dress that im­passe by serv­ing as a con­duit be­tween the pa­tient and the drug de­vel­op­er. The plat­form courts pa­tients with rare dis­eases by help­ing them ac­cess med­ical records and par­tic­i­pate in re­search, while for drug de­vel­op­ers, the com­pa­ny struc­tures the com­piled da­ta in an ef­fort to build re­search pro­grams and de­vel­op an ev­i­dence base palat­able for reg­u­la­to­ry au­thor­i­ties.

Un­til now, com­pa­nies big and small in the space have been stuck look­ing for pa­tients in 10, 20 or more hos­pi­tals, de­pend­ing on the dis­ease, not­ed co-founder Nan­cy Yu in an in­ter­view.

“So most com­pa­nies are grow­ing their in­ter­nal teams, as well as work­ing with con­tract re­search or­ga­ni­za­tions, and sub­con­tract­ing to up to some­times 15 dif­fer­ent soft­ware ven­dors to man­age the process,” Yu said.

Stream­lin­ing this process, and help­ing pa­tients them­selves ac­cess their da­ta and par­tic­i­pate in re­search, could change the way the rare dis­ease drug de­vel­op­ment is con­duct­ed, RD­MD hopes. This lofty goal was giv­en a $14 mil­lion in­jec­tion on Thurs­day in a Se­ries A round led by Spark Cap­i­tal, a ven­ture cap­i­tal firm that has pre­vi­ous­ly backed com­pa­nies such as Slack, Twit­ter and Ocu­lus.

“At the end of the day, rare dis­ease just re­quires a dif­fer­ent mod­el for drug de­vel­op­ment,” Yu said. “The chal­lenge is re­al­ly un­der­stand­ing what the dis­ease ac­tu­al­ly is and how you can best cre­ate and de­sign a pro­gram around ev­i­dence that ex­ists. It’s re­al­ly hard to de­sign a suc­cess­ful pro­gram if you don’t know much about the dis­ease.”

That re­quires pa­tient da­ta which, apart from be­ing scarce, are not all ac­ces­si­ble in one uni­ver­sal elec­tron­ic med­ical records sys­tem.

“So we get per­mis­sion from pa­tients … to be able to get all their records from their var­i­ous fa­cil­i­ties. And that’s both be­cause we want to em­pow­er pa­tients with that choice of opt­ing in to par­tic­i­pate in re­search, but it’s al­so a ne­ces­si­ty op­er­a­tional­ly for us to be able to get that in­for­ma­tion, be­cause it doesn’t sit in a cen­tral data­base some­where,” she said.

With the pa­tient’s con­sent, the da­ta are then col­lat­ed and dis­sem­i­nat­ed to com­pa­nies to give them a com­pre­hen­sive un­der­stand­ing of the dis­ease, and con­se­quent­ly, de­sign clin­i­cal tri­als, de­ter­mine what end­points and bio­mark­ers are rel­e­vant, and even ed­u­cate pay­ers and in­sur­ance com­pa­nies so they can cov­er the drugs up­on ap­proval.

There’s a lot that pa­tients can con­tribute to in terms of re­search that doesn’t nec­es­sar­i­ly in­volve par­tic­i­pat­ing in a clin­i­cal tri­al, she added.

“For ex­am­ple, some of this da­ta could be used to sup­port and elim­i­nate the need for a place­bo con­trol arm be­cause you’re just look­ing at da­ta that al­ready ex­ists in the re­al world around pa­tients and their nat­ur­al pro­gres­sion of dis­ease,” Yu said. “And so that’s cer­tain­ly some­thing that every­one is very fo­cused on and hop­ing to use the da­ta for.”

Sound fa­mil­iar? A New York-based tech com­pa­ny called Flat­iron Health that was swal­lowed by Swiss gi­ant Roche in 2018, has sim­i­lar plans to use re­al-world ev­i­dence to re­place more tra­di­tion­al clin­i­cal tri­al da­ta to help the FDA make de­ci­sions for can­cer drugs.

But tra­di­tion­al ran­dom­ized con­trolled tri­als (RCTs) are con­sid­ered the gold stan­dard to prove if a com­pound or in­ter­ven­tion is safe and ef­fec­tive for its in­tend­ed use — they are used to show that a ben­e­fit or ad­verse event ob­served is not a mat­ter of chance or bias.

But giv­en lim­i­ta­tions such as strict in­clu­sion cri­te­ria, which typ­i­cal­ly dis­qual­i­fy old­er pa­tients and those suf­fer­ing from co-mor­bidi­ties, RCTs can be an in­ac­cu­rate rep­re­sen­ta­tion of pa­tients in the re­al world. But skep­tics crit­i­cize that re­ly­ing sole­ly on re­al-world ev­i­dence could be dan­ger­ous, as the process has the po­ten­tial to in­tro­duce re­searcher bi­as­es, and is not sub­ject to the same method­olog­i­cal rig­or.

That be­ing said, un­like can­cer drug de­vel­op­ment, rare dis­ease tri­als are of­ten ham­pered by slow en­roll­ment due to the scarci­ty of pa­tients — and the FDA re­quires a much small­er body of ev­i­dence for de­ci­sion mak­ing. Sarep­ta Ther­a­peu­tics’ pi­o­neer­ing Duchenne mus­cu­lar dy­s­tro­phy (DMD) drug Ex­ondys 51, for in­stance, was ap­proved on the ba­sis of a tiny non-place­bo con­trolled tri­al that com­pared the ef­fect of the drug to the nat­ur­al course of the dis­ease.

De­spite stiff op­po­si­tion from with­in and out­side the agency from crit­ics who said da­ta were in­suf­fi­cient to war­rant ap­proval, the FDA cleared the drug for use in a sub­set of pa­tients with the rare mus­cle-wast­ing dis­ease in 2016, prompt­ing some to sug­gest the agency had bowed to pres­sure from pa­tient ad­vo­cates. On­ly in 2019 did Sarep­ta sub­mit plans for a con­fir­ma­to­ry tri­al, which is ex­pect­ed to be com­plet­ed by 2024. But in the mean­time, the com­pa­ny has since se­cured an­oth­er DMD ap­proval on the ba­sis of a 24 pa­tient study.

Yu, who pre­vi­ous­ly worked with con­sumer ge­net­ics com­pa­ny 23andme, set up RD­MD in late 2017 soon af­ter co-founder On­no Faber was di­ag­nosed with a rare ge­net­ic dis­ease called NF2 (Neu­rofi­bro­mato­sis Type 2), which af­fects 1 in 30,000 peo­ple.

“And so when we got to­geth­er, it was re­al­ly to fig­ure out how do we tack­le this — there are 7000 con­di­tions and like one in 10 peo­ple have a rare dis­ease that in ag­gre­gate, it’s a re­al­ly big prob­lem,” she not­ed.

On Thurs­day, the com­pa­ny al­so un­veiled a part­ner­ship with Bel­gium-based drug­mak­er UCB for up to five years to work on pro­gres­sive supranu­clear pal­sy (PSP), a rare neu­rode­gen­er­a­tive dis­ease.

In ad­di­tion, RD­MD is al­so part­ner­ing with pa­tient ad­vo­ca­cy or­ga­ni­za­tions and physi­cian con­sor­tiums across 12 con­di­tions, in­clud­ing the Chil­dren’s Tu­mor Foun­da­tion, Cure San­fil­ip­po Foun­da­tion and Na­tion­al Tay-Sachs & Al­lied Dis­eases As­so­ci­a­tion.

The Se­ries A round al­so in­clud­ed the par­tic­i­pa­tion of ex­ist­ing seed in­vestors Lux Cap­i­tal, Vil­lage Glob­al and Garu­da Ven­tures, and new in­vestor Maveron. The mon­ey will be used, among oth­er things, to ex­pand in­to a fur­ther 20 rare con­di­tions and en­sure the con­ti­nu­ity of re­search pro­grams through­out the Covid-19 pan­dem­ic.

ZS Per­spec­tive: 3 Pre­dic­tions on the Fu­ture of Cell & Gene Ther­a­pies

The field of cell and gene therapies (C&GTs) has seen a renaissance, with first generation commercial therapies such as Kymriah, Yescarta, and Luxturna laying the groundwork for an incoming wave of potentially transformative C&GTs that aim to address diverse disease areas. With this renaissance comes several potential opportunities, of which we discuss three predictions below.

Allogenic Natural Killer (NK) Cells have the potential to displace current Cell Therapies in oncology if proven durable.

Despite being early in development, Allogenic NKs are proving to be an attractive new treatment paradigm in oncology. The question of durability of response with allogenic therapies is still an unknown. Fate Therapeutics’ recent phase 1 data for FT516 showed relatively quicker relapses vs already approved autologous CAR-Ts. However, other manufacturers, like Allogene for their allogenic CAR-T therapy ALLO-501A, are exploring novel lymphodepletion approaches to improve persistence of allogenic cells. Nevertheless, allogenic NKs demonstrate a strong value proposition relative to their T cell counterparts due to comparable response rates (so far) combined with the added advantage of a significantly safer AE profile. Specifically, little to no risk of graft versus host disease (GvHD), cytotoxic release syndrome (CRS), and neurotoxicity (NT) have been seen so far with allogenic NK cells (Fig. 1). In addition, being able to harness an allogenic cell source gives way to operational advantages as “off-the-shelf” products provide improved turnaround time (TAT), scalability, and potentially reduced cost. NKs are currently in development for a variety of overlapping hematological indications with chimeric antigen receptor T cells (CAR-Ts) today, and the question remains to what extent they will disrupt the current cell therapy landscape.

Can­cer pow­er­house As­traZeneca rolls the dice on a $75M cash bet on a buzzy up­start in the on­col­o­gy field

After establishing itself in the front ranks of cancer drug developers and marketers, AstraZeneca is putting its scientific shoulder — and a significant amount of cash — behind the wheel of a brash new upstart in the biotech world.

The pharma giant trumpeted news this morning that it is handing over $75 million upfront to ally itself with Scorpion Therapeutics, one of those biotechs that was newly birthed by some top scientific, venture and executive talent and bequeathed with a fortune by way of a bankroll to advance an only hazily explained drug platform. And they are still very much in the discovery and preclinical phase.

A $3B+ peak sales win? Pfiz­er thinks so, as FDA of­fers a tardy green light to its JAK1 drug abroc­i­tinib

Back in the fall of 2020, newly crowned Pfizer chief Albert Bourla confidently put their JAK1 inhibitor abrocitinib at the top of the list of blockbuster drugs in the late-stage pipeline with a $3 billion-plus peak sales estimate.

Since then it’s been subjected to serious criticism for the safety warnings associated with the class, held back by a cautious FDA and questioned when researchers rolled out a top-line boast that their heavyweight contender had beaten the champ in the field of atopic dermatitis — Dupixent — in a head-to-head study.

Rob Califf ad­vances as Biden's FDA nom­i­nee, with a close com­mit­tee vote

Rob Califf’s second confirmation process as FDA commissioner is already much more difficult than his near unanimous confirmation under the Obama administration.

The Senate Health Committee on Thursday voted 13-8 in favor of advancing Califf’s nomination to a full Senate vote. Several Democrats voted against Califf, including Sen. Bernie Sanders and Sen. Maggie Hassan. Several other Democrats who aren’t on the committee, like West Virginia’s Joe Manchin and Ed Markey of Massachusetts, also said Thursday that they would not vote for Califf. Markey, Hassan and Manchin all previously expressed reservations about the prospect of Janet Woodcock as an FDA commissioner nominee too.

Bio­gen vows to fight CM­S' draft cov­er­age de­ci­sion for Aduhelm be­fore April fi­nal­iza­tion

Biogen executives made clear in an investor call Thursday they are not preparing to run a new CMS-approved clinical trial for their controversial Alzheimer’s drug anytime soon.

As requested in a draft national coverage decision from CMS earlier this week, Biogen and other anti-amyloid drugs will need to show “a meaningful improvement in health outcomes” for Alzheimer’s patients in a randomized, placebo-controlled trial to get paid for their drugs, rather than just the reduction in amyloid plaques that won Aduhelm its accelerated approval in June.

CRO own­er pleads guilty to ob­struct­ing FDA in­ves­ti­ga­tion in­to fal­si­fied clin­i­cal tri­al da­ta

The co-owner of a Florida-based clinical research site pleaded guilty to lying to an FDA investigator during a 2017 inspection, revealing that she falsely portrayed part of a GlaxoSmithKline pediatric asthma study as legitimate, when in fact she knew that certain data had been falsified, the Department of Justice said Wednesday.

Three other employees — Yvelice Villaman Bencosme, Lisett Raventos and Maytee Lledo — previously pleaded guilty and were sentenced in connection with falsifying data associated with the trial at the CRO Unlimited Medical Research.

‘Skin­ny la­bels’ on gener­ics can save pa­tients mon­ey, re­search shows, but re­cent court de­ci­sions cloud fu­ture

New research shows how generic drug companies can successfully market a limited number of approved indications for a brand name drug, prior to coming to market for all of the indications. But several recent court decisions have created a layer of uncertainty around these so-called “skinny” labels.

While courts have generally allowed generic manufacturers to use their statutorily permitted skinny-label approvals, last summer, a federal circuit court found that Teva Pharmaceuticals was liable for inducing prescribers and patients to infringe GlaxoSmithKline’s patents through advertising and marketing practices that suggested Teva’s generic, with its skinny label, could be employed for the patented uses.

How a tiny Swiss lab and two old blood sam­ples cre­at­ed one of the on­ly ef­fec­tive drugs against Omi­cron (and why we have so lit­tle of it)

Exactly a decade before a novel coronavirus broke out in Wuhan, Davide Corti — a newly-minted immunologist with frameless glasses and a quick laugh — walked into a cramped lab on the top floor of an office building two hours outside Zurich. He had only enough money for two technicians and the ceiling was so low in parts that short stature was a job requirement, but Corti believed it’d be enough to test an idea he thought could change medicine.
