In the decade since Nim­bus Ther­a­peu­tics built a com­pa­ny around com­pu­ta­tion and lit­tle-known phe­nom­e­na like al­losteric reg­u­la­tion, the in­dus­try has brimmed with al­go­rithm com­pa­nies and even a few chas­ing those same tar­gets. Still, a cou­ple of the old lead­ers think they can keep an edge.

“We’re very proud to have pi­o­neered the field,” Ger­ry Har­ri­man told End­points News. “And we’re al­so very proud to say our port­fo­lio is full of tar­gets that have al­losteric in­hibitors re­al­ly for the first time that has ever been de­scribed.”

Har­ri­man led Nim­bus’s ACC pro­gram — the part that sold to Gilead for up-to $1.2 bil­lion — be­fore she and for­mer Nim­bus CBO Jonathan Mon­tagu found­ed HotSpot Ther­a­peu­tics 3 years ago. The idea was to take the same prin­ci­ples and tech­nol­o­gy that led to the Gilead-li­censed drugs and un­leash it on a suite of dis­eases.

To­day Har­ri­man and Mon­tagu say they’ve de­vel­oped a long list of tar­gets, in­clud­ing two lead pro­grams in au­toim­mune dis­or­ders and rare meta­bol­ic dis­eases. They’ve al­so se­cured $65 mil­lion to bring them for­ward, in a Se­ries B round led by SR One, Lim­it­ed. And more news could be com­ing soon.

“We’ve got a num­ber of quite ad­vanced dis­cus­sions with Phar­ma,” Mon­tagu told End­points.

In the four years since Nim­bus sold its ACC pro­gram, Gilead’s NASH pro­gram has strug­gled, al­though the Nim­bus drug re­mains in de­vel­op­ment, in­clud­ing Phase II tri­al. In­ter­est in al­lostery has on­ly grown in the last half decade. Black Di­a­mond Ther­a­peu­tics jumped in a lit­tle over a year ago from a stealth mode to a bil­lion-dol­lar com­pa­ny with a $200 mil­lion IPO on its plat­form of al­losteric can­cer drugs.

These al­losteric sites are some­times known as hotspots (hence the biotech name), nodes that the body us­es for its own in­ter­nal mech­a­nism of com­mu­ni­ca­tion and reg­u­la­tion. These nodes can be dif­fi­cult to find, much less tar­get, but they hold sig­nif­i­cant po­ten­tial as drug tar­gets, both be­cause they are a “nat­ur­al” lo­cus of ac­tiv­i­ty and be­cause they of­fer a way to drug pro­teins that lack the easy grooves.

“Po­ten­cy, se­lec­tive­ly, drug-like prop­er­ties are the re­al ad­van­tages of this ap­proach,” Mon­tagu said. “And for those tar­gets that don’t have ac­tive sites, it’s re­al­ly the on­ly way to build a first-in-class [drug].”

HotSpot is built around their com­put­er plat­form that us­es a slew of dif­fer­ent al­go­rithms to search for these al­losteric sites. They go af­ter pro­teins that ge­net­ics have shown dri­ve dis­ease. They start with the pro­tein struc­ture — of a ki­nase — and then build evo­lu­tion­ary maps that, with ma­chine learn­ing, al­low you to scout out the com­mon reg­u­la­to­ry spots.

“We knew that a pri­ori that not one sin­gle tech­nol­o­gy would al­low us to a sys­tem­at­ic un­cov­er­ing of reg­u­la­to­ry hotspots,” Har­ri­man said. “So we put about a dozen dif­fer­ent al­go­rithms to­geth­er that helps us to find the reg­u­la­to­ry hotspots, de­ter­mine if they’re drug­gable, un­der­stand the struc­ture func­tion, un­veil these mol­e­c­u­lar fin­ger­prints of fin­ger­tips.”

HotSpot will now look to get clin­i­cal da­ta on two drugs by 2022. One is an al­losteric in­hibitor of PKC-theta, an en­zyme phar­ma com­pa­nies have with more con­ven­tion­al in­hibitors, to lit­tle suc­cess. HotSpot will test it in au­to-im­mune dis­eases dri­ven by reg­u­la­to­ry T cells and Th2 cells. The sec­ond is an in­hibitor for S6 ki­nase, an en­zyme that’s been stud­ied as a treat­ment for obe­si­ty and that Hot­pot will test on rare meta­bol­ic dis­eases.

But those, Mon­tagu said, are on­ly the first cou­ple drugs they’re bring­ing for­ward in-house. The com­pa­ny is al­so work­ing on drug­ging tran­scrip­tion fac­tors, the DNA-reg­u­lat­ing pro­teins that play a cru­cial role in a host of dis­eases but have been dif­fi­cult to drug be­cause they lack easy grooves in­to which you could sneak a small mol­e­cule. That pro­gram has gen­er­at­ed in­ter­est from Phar­ma, Mon­tagu said, as have some of their im­muno-on­col­o­gy find­ings.

”Even big com­pa­nies find im­muno-on­col­o­gy chal­leng­ing,” he said. “So we’d like to part­ner the I/O as­sets and ad­dress our­selves in the im­munol­o­gy space.”

Cor­rec­tion: The sto­ry has been up­dat­ed to cor­rect the sta­tus of the Gilead’s ACC drug.

Nearly three years after okaying the CAR-Ts Yescarta and Kymriah, the FDA has approved a new CD19 therapy.

MorphoSys’ Monjuvi, or tafasitamab-cxix, was cleared Friday for use in refractory diffuse large B-cell lymphoma (DBLCL). The approval sets up both MorphoSys and their commercial partner Incyte to compete with Gilead and Novartis in the ultra-competitive indication, where similar trial results and far easier delivery could allow them to cut a fair share of the market.

Two weeks after the FDA lifted its clinical hold on their lead drug, CymaBay said it showed positive results in an aborted Phase III trial.

The drug, a small molecule known as seladelpar, had been in development for three different liver conditions before an independent review of a NASH study last year showed that it might actually be damaging patient’s liver cells. The FDA slapped a clinical hold across all three trials, only lifting it last month when an FDA review determined that the drug hadn’t caused liver damage.

Sanofi is facing a formal investigation on manslaughter charges, due to accusations that its epilepsy drug Depakine caused birth malfunctions and slow neurological development when taken during pregnancy.

The French pharma was formally charged in February, years after evidence surfaced that the drug, sodium valproate, posed neurodevelopmental risks. Sodium valproate first hit the market in 1967 for the treatment of epilepsy and bipolar disorder, and is currently prescribed in more than 100 countries.

Less than a year after pulling in an impressive $62 million Series C round, PMV Pharma is back at it again.

The Cranbury, NJ-based biotech announced Monday an additional $70 million in Series D financing as it seeks to develop cancer therapies targeting p53 mutations. Additionally, PMV also introduced longtime biotech entrepreneur Rich Heyman as chairman of the board of directors.

“This financing provides PMV Pharma with the resources to expand our pipeline and to potentially advance multiple p53 therapies into the clinic,” said PMV president and CEO David Mack in a statement.

Back in March, when Kymera Therapeutics closed $102 million in Series C funding led by Biotechnology Value Fund and Redmile Group, CEO Nello Mainolfi noted the protein degradation player was “at the cusp of transitioning” into a fully integrated R&D company. Five months and a major Sanofi pact later, he’s back asking for another little push to get there.

Kymera has penciled in $100 million in its first IPO pitch — although given the public market’s seemingly insatiable appetite for biotechs these days the final figure is anyone’s guess.

Eli Lilly and the NIH are about to start a first-of-its-kind trial that researchers and developers have talked about for months as a way of providing temporary immunity to the most at-risk populations.

Lilly announced this morning that it will start a 2,400-person trial with the National Institute for Allergy and Infectious Diseases to test whether its experimental Covid-19 neutralizing antibody can prevent people in nursing homes and assisted living facilities from developing the disease. The idea, known as passive immunity, is that rather than waiting on a vaccine to induce people to develop antibodies, doctors can give them lab-grown antibodies. Ideally, those antibodies will either attack the new SARS-CoV-2 infection, if the patient has recently been exposed, or persist in the blood for several weeks and prevent infection or disease for that period.

Just a week after its lead program began enrolling patients in a study to treat Covid-19, Immunic Therapeutics is making more waves.

This time, the biotech is providing a glimpse at topline data from a Phase II trial studying the efficacy of vidofludimus calcium, or IMU-838, in relapsing-remitting multiple sclerosis patients. Taken orally, the candidate met its primary endpoint in reducing the cumulative number of combined unique active MRI lesions after 24 weeks for a 45 mg dose compared to a placebo, as well as a key secondary endpoint in such reductions for the 30 mg dose.
