Canaan backs Pathios' search for small mol­e­cule drugs that hit 'or­phan' GCPR

As fruit­ful as G pro­tein-cou­pled re­cep­tors have proved for mod­ern med­i­cine — by com­mon es­ti­mates, more than 30% of FDA-ap­proved drugs tar­get this class of pro­teins — there are still dozens of “or­phan” GPCRs whose en­doge­nous lig­ands are poor­ly un­der­stood. One of them is GPR65, a pH sens­ing re­cep­tor that British biotech Pathios be­lieves plays a cru­cial role in both can­cer and au­toim­mune dis­eases.

Tom Mc­Carthy

Ox­ford-based Pathios was found­ed in 2017 by Tom Mc­Carthy, a biotech vet and one-time VC who has two oth­er ven­tures to his name: Spinifex Phar­ma­ceu­ti­cals, a pain-fo­cused com­pa­ny ul­ti­mate­ly ac­quired by No­var­tis; and the im­muno-on­col­o­gy up­start Grey Wolf. With $8.8 mil­lion in Se­ries A fund­ing and Stu­art Hugh­es com­ing on board as CEO, Pathios is well on the way to gen­er­at­ing its first leads.

Hugh­es most re­cent­ly head­ed phar­ma­col­o­gy at Ver­tex’s Ox­ford­shire of­fice, hav­ing cut his teeth in drug dis­cov­ery at Eli Lil­ly. The em­pha­sis on lean and ef­fec­tive project lead­er­ship he’s used to is very much present at Pathios, he said, where he will be man­ag­ing a small team work­ing with a cadre of ex­ter­nal part­ners.

“It re­al­ly is a very fo­cused tech­ni­cal small mol­e­cule drug dis­cov­ery ef­fort,” Hugh­es told End­points News.

Ear­li­er this year the biotech brought in Syg­na­ture Dis­cov­ery to hunt for mod­u­la­tors of GPR65, lever­ag­ing the CRO’s med­i­c­i­nal chem­istry ex­per­tise and screen­ing tools. The CRO took a small stake in Pathios as part of the pay­ment.

Stu­art Hugh­es

The idea be­hind their laser-fo­cused pur­suit of GPR65 has two di­men­sions: Not on­ly does GPR65 ap­pear to be char­ac­ter­is­tic of cer­tain T helper 17 cell pop­u­la­tions that re­port­ed­ly con­tribute to the pathol­o­gy of au­toim­mune con­di­tions such as anky­los­ing spondyli­tis and pso­ri­at­ic arthri­tis, but it al­so ap­pears to dri­ve tu­mor as­so­ci­at­ed macrophages “to adopt a phe­no­type that sup­ports can­cer im­mune eva­sion,” ac­cord­ing to the com­pa­ny.

As GPR65 tends to be ac­tive in acidic en­vi­ron­ments, Hugh­es added, can­cers that are par­tic­u­lar­ly gly­colyt­ic — ones that pro­duce lac­tic acid — such as ad­vanced melanoma could be es­pe­cial­ly suit­ed for this ap­proach.

“We are now on the verge of clear­ly defin­ing the bi­o­log­i­cal process­es GPR65 con­trols, (its) ge­net­ic links to dis­ease and how small mol­e­cules can mod­u­late its sig­nalling,” Mc­Carthy said in a state­ment.

While the spe­cial prop­er­ties of GPR65 present some unique chal­lenges, “the good thing is GPCRs ob­vi­ous­ly are a very drug­gable tar­get class,” Hugh­es said.

Canaan Part­ners, which led the Se­ries A for Grey Wolf in Feb­ru­ary and had backed Spinifex, al­so played a promi­nent role here along­side Canaan and Aus­tralia’s Med­ical Re­search Com­mer­cial­i­sa­tion Fund man­aged by Bran­don Cap­i­tal.

Im­ple­ment­ing re­silience in the clin­i­cal tri­al sup­ply chain

Since January 2020, the clinical trials ecosystem has quickly evolved to manage roadblocks impeding clinical trial integrity, and patient care and safety amid a global pandemic. Closed borders, reduced air traffic and delayed or canceled flights disrupted global distribution, revealing how flexible logistics and supply chains can secure the timely delivery of clinical drug products and therapies to sites and patients.

Al­ny­lam gets the green light for drug #3 — and CEO John Maraganore is ready to roll

Score another early win at the FDA for Alnylam.

The FDA put out word today that the agency has approved its third drug, lumasiran, for primary hyperoxaluria type 1, better known as PH1.

An ultra rare genetic condition, Alnylam CEO John Maraganore says there are only some 1,000 to 1,700 patients in the US and Europe at any particular point. The patients, mostly kids, suffer from an overproduction of oxalate in the liver that spurs the development of kidney stones, right through to end stage kidney disease.

In fi­nal days at Mer­ck, Roger Perl­mut­ter bets big on a lit­tle-known Covid-19 treat­ment

Roger Perlmutter is spending his last days at Merck, well, spending.

Two weeks after snapping up the antibody-drug conjugate biotech VelosBio for $2.75 billion, Merck announced today that it had purchased OncoImmune and its experimental Covid-19 drug for $425 million. The drug, known as CD24Fc, appeared to reduce the risk of respiratory failure or death in severe Covid-19 patients by 50% in a 203-person Phase III trial, OncoImmune said in September.

UP­DAT­ED: As­traZeneca, Ox­ford on the de­fen­sive as skep­tics dis­miss 70% av­er­age ef­fi­ca­cy for Covid-19 vac­cine

On the third straight Monday that the world wakes up to positive vaccine news, AstraZeneca and Oxford are declaring a new Phase III milestone in the fight against the pandemic. Not everyone is convinced they will play a big part, though.

With an average efficacy of 70%, the headline number struck analysts as less impressive than the 95% and 94.5% protection that Pfizer/BioNTech and Moderna have boasted in the past two weeks, respectively. But the British partners say they have several other bright spots going for their candidate. One of the two dosing regimens tested in Phase III showed a better profile, bringing efficacy up to 90%; the adenovirus vector-based vaccine requires minimal refrigeration, which may mean easier distribution; and AstraZeneca has pledged to sell it at a fraction of the price that the other two vaccine developers are charging.

Bob Nelsen rais­es $800M and re­cruits a star-stud­ded board to build the 'Fox­con­n' of biotech

Bob Nelsen spent his pandemic spring in his Seattle home, talking on the phone with Luciana Borio, the scientist who used to run pandemic preparedness on the National Security Council, and fuming with her about the dire state of American manufacturing.

Companies were rushing to develop vaccines and antibodies for the new virus, but even if they succeeded, there was no immediate supply chain or infrastructure to mass-produce them in a way that could make a dent in the outbreak.

Tech bil­lion­aire Pe­ter Thiel backs a lead­ing psy­che­del­ic drug de­vel­op­er

Right on the heels of investing in antibody drug developer AbCellera, Facebook billionaire Peter Thiel has jumped into a syndicate putting up $125 million for a company with a portfolio of psychedelic drugs in the clinic for mental health.

The C round — which includes a $32 million conversion of notes to equity — will fuel the development programs at ATAI Life Sciences, a Berlin-based biotech that has assembled a portfolio of companies with psychedelic and non-psychedilc approaches to depression, anxiety and addiction.

Carl Hansen, AbCellera CEO (University of British Columbia)

From a pair of Air Jor­dans to a $200M-plus IPO, Carl Hansen is craft­ing an overnight R&D for­tune fu­eled by Covid-19

Back in the summer of 2019, Carl Hansen left his post as a professor at the University of British Columbia to go full time as the CEO at a low-profile antibody shop he had founded called AbCellera.

As biotech CEOs go, even after a fundraise Hansen wasn’t paid a whole heck of a lot. He ended up earning right at $250,000 for the year. His compensation package included a loan — which he later paid back — and a pair of Air Jordan tennis shoes. His newly-hired CFO, Andrew Booth, got a sweeter pay packet than that — which included his own pair of Air Jordans.

Scoop: SR One crew com­pletes a com­pli­cat­ed spin­out from Glax­o­SmithK­line. And now they have a $500M fund to in­vest on their own

It’s taken close to 2 years, but Simeon George and his team at SR One have completed their spinout from GlaxoSmithKline, ending a saga as one of the longest running venture arms of Big Pharma as they go out on their own to forge the next chapter with a new and independent $500 million fund.

GSK is sticking with the spinout, this time as a minority investor — though a big one. And I’m told that the R&D group at GSK will remain involved in evaluating their new plays, helping with the scientific due diligence involved in scouting the world for new opportunities during a period of explosive growth in biotech investing.

Cata­ma­ran Bio sails in­to the CAR-NK wa­ters with a $42M launch round

Catamaran Bio’s founding members decided to jump into the CAR-NK game last December over drinks at a trendy bar in Boston.

They were sitting around a table, discussing an MD Anderson study which provided some of the first clinical proof that natural killer (NK) cells can be reengineered to attack tumors, much like CAR-T therapies. It was a “long and lively” discussion, COO Mark Boshar recalls. And by the time it was over, they had a starting point to launch a company.
