As with chil­dren stud­ies, Su­per­nus AD­HD drug shows fast on­set of ac­tion in ado­les­cents

Pos­i­tive piv­otal da­ta on Su­per­nus’ $SUPN AD­HD drug in chil­dren gave in­vestors pause ear­li­er this month be­cause of the lack of dose re­sponse at the high­er 400 mg dose, which weighed on the shares. On Thurs­day, the drug de­vel­op­er fol­lowed up with large­ly sim­i­lar Phase III da­ta from an ado­les­cent study, but the drug’s swift on­set of ac­tion, as seen in pre­vi­ous tri­als with chil­dren, may be a key dif­fer­en­tia­tor from ex­ist­ing AD­HD non-stim­u­lant med­ica­tions.

Two dos­es (200 mg/400 mg) of the drug, SPN-812, were test­ed against a place­bo in the 310-pa­tient ado­les­cent study P302. At week 6, pa­tients re­ceiv­ing SPN-812 200 mg and 400 mg had a -16.0 point change (p=0.0232) and a -16.5 point change (p=0.0091) on an AD­HD rat­ing scale, ver­sus -11.4 for those on the place­bo — meet­ing the main goal of the study. Over­all, pa­tients re­ceiv­ing 200 mg and 400 mg had an ef­fect size of 0.47 and 0.50, re­spec­tive­ly. Sig­nif­i­cant­ly, the high­er dose start­ed to work as soon as the first week, the com­pa­ny said.

“These da­ta fur­ther re­in­force the ef­fec­tive­ness of SPN-812 in pa­tients with AD­HD…with a fa­vor­able safe­ty and tol­er­a­bil­i­ty pro­file,” said CEO Jack Khat­tar in a state­ment. “We now have pos­i­tive da­ta prov­ing the ef­fi­ca­cy and safe­ty of SPN-812 in all AD­HD pa­tient pop­u­la­tions; pos­i­tive Phase III da­ta in chil­dren 6-11 years old and ado­les­cents 12-17 years old, and pos­i­tive Phase IIa da­ta in adults.”

An­oth­er Phase III study (P304) in ado­les­cents is ex­pect­ed to read out in the first quar­ter of 2019. But buoyed by the da­ta so far, Su­per­nus ex­pects to sub­mit a mar­ket­ing ap­pli­ca­tion by the end of the first quar­ter of 2019 and to launch — pend­ing FDA ap­proval — in the sec­ond half of 2020, it said on Thurs­day. The com­pa­ny’s shares edged up about 2.5% be­fore the bell.

In the first week of De­cem­ber, twin stud­ies eval­u­at­ing the ex­per­i­men­tal non-stim­u­lant drug in chil­dren showed sim­i­lar ef­fect sizes. In the P301 study, the 100 mg and 200 mg demon­strat­ed an ef­fect size of 0.54 and 0.57, re­spec­tive­ly. In the P303 tri­al, pa­tients re­ceiv­ing 200 mg and 400 mg had an ef­fect size of 0.46 and 0.49. Three out of the four dos­es were ob­served to have start­ed work­ing in week 1. But the com­pa­ny’s stock fell be­cause of the lack of dose-re­sponse seen with the high­er 400 mg dose, and wor­ries that the drug may have not per­formed well enough to dif­fer­en­ti­ate it­self from ex­ist­ing AD­HD drugs such as Lil­ly’s Stat­tera and Shire’s In­tu­niv.

Lil­ly’s $LLY Strat­tera — which achieved an ef­fect size of 0.4 to 0.6 in tri­als — was the first non-stim­u­lant med­ica­tion ap­proved for AD­HD, but it can take more than 6 weeks to start work­ing. Last year it went gener­ic, and is used for both chil­dren and ado­les­cents.

In a note ear­li­er this month, Jef­feries’ David Stein­berg sug­gest­ed that the over­all pro­file of SPN-812 was favourable. If ap­proved, it is set to reap peak sales of $400 mil­lion, he said.

#UK­BIO19: Join GSK’s Hal Bar­ron and a group of top biotech ex­ecs for our 2nd an­nu­al biotech sum­mit in Lon­don

Over the past 10 years I’ve made a point of getting to know the Golden Triangle and the special role the UK biopharma industry plays there in drug development. The concentration of world class research institutes, some of the most accomplished scientists I’ve ever seen at work and a rising tide of global investment cash leaves an impression that there’s much, much more to come as biotech hubs are birthed and nurtured.

Deborah Dunsire. Lundbeck

UP­DAT­ED: Deb­o­rah Dun­sire is pay­ing $2B for a chance to leap di­rect­ly in­to a block­buster show­down with a few of the world's biggest phar­ma gi­ants

A year after taking the reins as CEO of Lundbeck, Deborah Dunsire is making a bold bid to beef up the Danish biotech’s portfolio of drugs in what will likely be a direct leap into an intense rivalry with a group of giants now carving up a growing market for new migraine drugs.

Bright and early European time Monday morning the company announced that it will pay up to about $2 billion to buy Alder, a little biotech that is far along the path in developing a quarterly IV formulation of a CGRP drug aimed at cutting back the number of crippling migraines patients experience each month. In a followup call, Dunsire also noted that the company will likely need 200 to 250 reps for this marketing task on both sides of the Atlantic. And analysts were quick to note that the dealmaking at Lundbeck isn’t done, with another $2 billion to $3 billion available for more deals to beef up the pipeline.

It’s fi­nal­ly over: Bio­gen, Ei­sai scrap big Alzheimer’s PhI­I­Is af­ter a pre­dictable BACE cat­a­stro­phe rais­es safe­ty fears

Months after analysts and investors called on Biogen and Eisai to scrap their BACE drug for Alzheimer’s and move on in the wake of a string of late-stage failures and rising safety fears, the partners have called it quits. And they said they were dropping the drug — elenbecestat — after the independent monitoring board raised concerns about…safety.

We don’t know exactly what researchers found in this latest catastrophe, but the companies noted in their release that investigators had determined that the drug was flunking the risk/benefit analysis.

Scott Got­tlieb has a new board po­si­tion to add to the re­sume — and this one is fo­cused on a fa­vorite sub­ject

Scott Gottlieb has another position to add to his lengthy roster of boards and advisory roles in the wake of his departure from the helm of the FDA.

He’ll be joining the advisory board of FasterCures, a think tank which former junk bond king Michael Milken set up to help drive more drugs to the market, looking to accelerate drug R&D. That’s a subject close to the heart of Gottlieb, who blazed a trail at the FDA focused on hustling up the process. That helped endear him to the industry, making him one of the most popular commissioners in FDA history.

Karyopharm lines up $150 mil­lion cash in­jec­tion to back con­tro­ver­sial drug launch

Karyopharm has entered into a royalty agreement worth up to $150 million to back the launch of their multiple myeloma drug — recently approved by the FDA over the objections of a majority of the agency’s outside experts.

The deal with HealthCare Royalty Partners, worth $75 million now and $75 million once certain regulatory and commercial milestones have been reached, will fund the commercialization of Karyopharm’s oral SINE compound Xpovio (selinexor) for patients with multiple myeloma who have already had at least four prior therapies. The money will help Karyopharm as it markets its newly approved drug and pushes through clinical trials testing the drug on refractory multiple myeloma patients with one to three therapies and patients with treatment-resistant diffuse large B-cell lymphoma. It will give Karyopharm a cushion through mid-2021.

Af­ter a run of CT­LA-4 com­bo fail­ures, sci­en­tists spot­light a way to make it work — in se­lect pa­tients

CTLA-4/PD-(L)1 combinations have been one of the El Dorados of oncology, its promise forever behind that next hill but apparently unattainable after a series of pivotal clinical failures. But researchers at New York’s Memorial Sloan Kettering Cancer Center and the Technical University of Munich think they may know how to fix what’s wrong and boost the drive to next-gen cancer combos.

In a preclinical animal research program, researchers found that within a cell, checkpoints rely on a specific molecule — RNA-sensing molecule RIG-I — to work. If that sounds familiar, it’s because it has already been identified as a target for boosting immune responses and was subject to at least one Phase I/II trial. Pfizer in December allied itself with Kineta with $15 million upfront and $505 million in potential milestones to develop RIG-I immunotherapies, and three years ago Merck purchased German upstart Rigontec for $137 million upfront and over $400 million in potential milestones for the same purpose.

Pur­due Phar­ma files for bank­rupt­cy as first step in $10B opi­oid set­tle­ment

It’s settled. Purdue Pharma has filed for bankruptcy as part of a deal that would see the OxyContin maker hand over $10 billion in cash and other contributions to mitigate the opioid crisis — without acknowledging any wrongdoing in the protracted epidemic that’s resulted in hundreds of thousands of deaths.

The announcement came two weeks after news of a proposed settlement surfaced and largely confirm what’s already been reported.

MSK picks brain can­cer ex­pert Lisa DeAn­ge­lis as its next CMO — fol­low­ing José Basel­ga’s con­tro­ver­sial ex­it

It’s official. Memorial Sloan Kettering has picked a brain cancer expert as its new physician-in-chief and CMO, replacing José Baselga, who left under a cloud after being singled out by The New York Times and ProPublica for failing to properly air his lucrative industry ties.

His replacement, who now will be in charge of MSK’s cutting-edge research work as well as the cancer care delivered by hundreds of practitioners, is Lisa M. DeAngelis. DeAngelis had been chair of the neurology department and co-founder of MSK’s brain tumor center and was moved in to the acting CMO role in the wake of Baselga’s departure.
