The stel­lar an­ti­body shop at Re­gen­eron wins a ‘break­through’ tag for its next big PhI­II drug

Richard Dun­bar

Re­gen­eron $REGN has one of the best track records in the busi­ness when it comes to build­ing amaz­ing­ly ef­fec­tive an­ti­bod­ies. It did it with Dupix­ent for eczema and Pralu­ent for cho­les­terol. And now one of its Phase II stars just earned a break­through tag from the FDA, which puts it on the in­side track at the agency as it goes in­to piv­otal stud­ies for slash­ing triglyc­eride.

The drug is evinacum­ab. The tar­get is once again ex­tra­or­di­nar­i­ly high lev­els of LDL cho­les­terol. But the tar­get is dif­fer­ent. This an­ti­body tack­les an­giopoi­etin-like pro­tein 3, or ANGPTL3. ANGPTL3 in­hibits lipopro­tein li­pase and en­dothe­lial li­pase, play­ing a key role in lipopro­tein me­tab­o­lism.

Re­searchers are test­ing the drug in hy­per­c­ho­les­terolemia in pa­tients with rare cas­es of Ho­mozy­gous Fa­mil­ial Hy­per­c­ho­les­terolemia (HoFH). And it could fit com­fort­ably in their port­fo­lio, right next to Pralu­ent.

The FDA cit­ed da­ta from a small Phase II study for the drug in hand­ing out the BTD, which is de­signed to open doors to de­vel­op­ers as they ad­vance sig­nif­i­cant new drugs with high po­ten­tial through the clin­ic. In the Phase II in­ves­ti­ga­tors mon­i­tored triglyc­eride lev­els for at least five months fol­low­ing an in­jec­tion. Six dos­es were test­ed and in the top three dose-groups, triglyc­erides were cut by 64% to 73%. At the time, Penn’s Richard Dun­bar not­ed two dis­tinct ad­van­tages in man­ag­ing triglyc­erides: re­duc­ing hos­pi­tal­iza­tion for pan­cre­ati­tis pa­tients and re­duc­ing the risk of heart dis­ease.

“Cur­rent med­ica­tions such as fi­brates or pre­scrip­tion fish oils ef­fec­tive­ly low­er triglyc­erides, but leave much to be de­sired, each on­ly low­er­ing lev­els by 20 to 50 per­cent,” Dun­bar said at the time. “Val­i­dat­ing a drug that low­ers triglyc­erides well be­yond that range would un­doubt­ed­ly take us to the next lev­el, par­tic­u­lar­ly since it could be com­bined with cur­rent oral med­ica­tions for those pa­tients with ex­tra­or­di­nar­i­ly high triglyc­erides who of­ten can’t achieve safe lev­els with our usu­al med­ica­tions. A sim­i­lar ap­proach has been tak­en for low­er­ing cer­tain cho­les­terol with the ad­vent of PC­SK9 in­hibitors, which uti­lize a sim­i­lar mon­o­clon­al an­ti­body mech­a­nism.”

Prov­ing that and win­ning cov­er­age from pay­ers won’t be easy, as Re­gen­eron and its close part­ner Sanofi are well aware af­ter their Pralu­ent ex­pe­ri­ence. And Sanofi — which shoul­ders much of the Phase III load on its part­nered ther­a­pies — al­ready opt­ed out of this an­ti­body. But Re­gen­eron seems ready to push this drug in­to their whol­ly-owned late-stage pipeline, tear­ing off an­oth­er ma­jor Phase III ef­fort for a re­mark­ably ef­fec­tive R&D group.

The FDA just ap­proved the third Duchenne MD drug. And reg­u­la­tors still don’t know if any of them work

Last year Sarepta hit center stage with the FDA’s controversial reversal of its CRL for the company’s second Duchenne muscular dystrophy drug — after the biotech was ambushed by agency insiders ready to reject a second pitch based on the same disease biomarker used for the first approval for eteplirsen, without actual data on the efficacy of the drug.

On Wednesday the FDA approved the third Duchenne MD drug, based on the same biomarker. And regulators were ready to act yet again despite the lack of efficacy data.

Cell and Gene Con­tract Man­u­fac­tur­ers Must Em­brace Dig­i­ti­za­tion

The Cell and Gene Industry is growing at a staggering 30% CAGR and is estimated to reach $14B by 20251. A number of cell, gene and stem cell therapy sponsors currently have novel drug substances and products and many rely on Contract Development Manufacturing Organizations (CDMO) to produce them with adherence to stringent regulatory cGMP conditions. Cell and gene manufacturing for both autologous (one to one) and allogenic (one to many) treatments face difficult issues such as: a complex supply chain, variability on patient and cellular level, cell expansion count and a tight scheduling of lot disposition process. This complexity affects quality, compliance and accountability in the entire vein-to-vein process for critically ill patients.

UP­DAT­ED: On the heels of a snap $1B raise, Cure­Vac out­lines plans to seek emer­gency OK for their Covid-19 vac­cine in a mat­ter of months

CureVac is going from being one of the quietest players in the race to develop a new vaccine to fight the worst public health crisis in a century to a challenger for the multibillion-dollar market that awaits the first vaccines to make it over the finish line. Typically low-key at a time of brash comments and incredibly ambitious development timelines from the leaders, CureVac now is jumping straight into the spotlight.

US gov­ern­ment re­port­ed­ly be­gins prepar­ing for Covid-19 chal­lenge tri­als. Are they eth­i­cal?

Controversial human challenge trials for potential Covid-19 vaccines reportedly have a new booster — the US government.

Scientists working for the government have begun manufacturing a strain of the novel coronavirus that could be used in such studies, Reuters reported Friday morning. The trials would enroll healthy volunteers to be vaccinated and then intentionally infected with a weakened coronavirus.

Eye­ing in-vi­vo edit­ing, Mam­moth li­cens­es Jen­nifer Doud­na’s new CRISPR en­zyme

Last month, Jennifer Doudna revealed in Science a new, “hyper-compact” CRISPR enzyme that was half the size of traditional CRISPR enzymes and could, she suspected, offer a new, more versatile tool for gene editing.

Now, the University of California-Berkeley has licensed that enzyme, known as Casφ, exclusively to a biotech startup she and two former students set up three years ago: Mammoth Biosciences. It’s the second new CRISPR protein Mammoth has licensed from Doudna’s lab, after they licensed Cas14 in 2019.

Sanofi vet Kather­ine Bowdish named CEO of PIC Ther­a­peu­tics; As the world Terns: Liv­er dis­ease biotech makes ex­ec­u­tive changes

PIC Therapeutics hasn’t raised much money, yet. But the fledgling biotech has attracted a high-profile player to the helm.

The Boston-based biotech has handed the reins to Katherine Bowdish as its president and CEO. Bowdish will also join the board of directors of PIC. Bowdish joins from Sanofi where she served as VP and head of R&D strategy, as well as helping launch and lead Sanofi Sunrise, a venture investment and partnering vehicle at Sanofi. Before that, Bowdish held several exec roles at Permeon Biologics, Anaphore, Alexion Pharmaceuticals and Prolifaron (acquired by Alexion).

Bio­Marin CSO diss­es ri­vals for the he­mo­phil­ia A gene ther­a­py crown: Way be­hind, fac­ing big re­cruit­ment chal­lenges and at best a .6 on the gen-one scale

The leader in the race to a hemophilia A gene therapy does not like to be compared unfavorably to the competition. And when their top execs do the comparing, don’t look for any modesty — BioMarin, they say, owns the lead.

As Factor VIII expression wanes over time, quite a few analysts have raised questions about the kind of future BioMarin’s gene therapy — a supposed once-and-done treatment — faces if it stops working. But just 7 days away from their PDUFA date, with high odds of success, the top execs clearly feel that they are way out front, while promising their rivals will discover there’s a tough slog ahead trying to pursue trials where large numbers of patients are ineligible for new therapies.

Cal­lid­i­tas bets up to $102M on a biotech buy­out, snag­ging a once-failed PBC drug

After spending years developing its oral formulation of the corticosteroid budesonide, Sweden’s Calliditas now has its sights set on the primary biliary cholangitis field.

The company will buy out France-based Genkyotex, and it’s willing to bet up to €87 million ($102 million) that Genkyotex’s failed Phase II drug, GKT831, will do better in late-stage trials.

Under the current agreement, Calliditas $CALT will initially pay €20.3 million in cash for 62.7% of Genkyotex (or €2.80 a piece for 7,236,515 shares) in early October, then circle back for the rest of Genkyotex’s shares under the same terms. If nothing changes, the whole buyout will cost Calliditas €32.3 million, plus up to  €55 million in contingent rights.

FDA puts up a red light for Pas­sage Bio’s first gene ther­a­py pro­gram, de­lay­ing a pro­gram from James Wilson's group at Penn

Gene therapy pioneer James Wilson spearheaded animal studies demonstrating the potential of new treatments injected directly into the brain, looking to jumpstart a once-and-done fix for an extraordinarily rare disease called GM1 gangliosidosis in infants. His team at the University of Pennsylvania published their work on monkeys and handed it over to Passage Bio, a Wilson-inspired startup building a pipeline of gene therapies — with an IND for PBGM01 to lead the way.
