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.

How one start­up fore­told the neu­ro­science re­nais­sance af­ter '50 years of shit­show'

In the past couple of years, something curious has happened: Pharma and VC dollars started gushing into neuroscience research.

Biogen’s controversial new Alzheimer’s drug Aduhelm has been approved on the basis of removing amyloid plaque from the brain, but the new neuro-focused pharma and biotechs have much loftier aims. Significantly curbing or even curing the most notorious disorders would prove the Holy Grail for a complex system that has tied the world’s best drug developers in knots for decades.

Am­gen bel­lies back up to the M&A ta­ble for an­oth­er biotech buy­out, this time with a $2.5B deal for an an­ti­body play­er fo­cused on PS­MA

Five months after Amgen CEO Bob Bradway stepped up to the M&A table and acquired Five Prime for $1.9 billion, following up with the smaller Rodeo acquisition, he’s gone back in for another biotech buyout.

This time around, Amgen is paying $900 million cash while committing up to $1.6 billion in milestones to bag the privately held Teneobio, an antibody drug developer that has expertise in developing new bispecifics and multispecifics. In addition, Amgen cited Teneobio’s “T-cell engager platform, which expands on Amgen’s existing leadership position in bispecific T-cell engagers by providing a differentiated, but complementary, approach to Amgen’s current BiTE platform.”

De­nali slips as a snap­shot of ear­ly da­ta rais­es some trou­bling ques­tions on its pi­o­neer­ing blood-brain bar­ri­er neu­ro work

Denali Therapeutics had drummed up considerable hype for their blood-brain barrier technology since launching over six years ago, hype that’s only intensified in the last 14 months following the publications of a pair of papers last spring and proof of concept data earlier this year. On Sunday, the South San Francisco-based biotech gave the biopharma world the next look at in-human data for its lead candidate in Hunter syndrome.

Why is On­col­o­gy Drug De­vel­op­ment Re­search Late to the Dig­i­tal Bio­mark­ers Game?

During the recent Annual ASCO Meeting, thousands of cancer researchers and clinicians from across the globe joined together virtually to present and discuss the latest findings and breakthroughs in cancer research and care. There were more than 5000+ scientific abstracts presented during this event, yet only a handful involved the use of motion-tracking wearables to collect digital measures relating to activity, sleep, mobility, functional status, and/or quality of life. Although these results were a bit disappointing, they should come as no surprise to those of us in the wearable technology field.

Google-backed Cal­i­co dou­bles down on an­ti-ag­ing R&D pact with Ab­b­Vie as part­ners ante up $1B, start to de­tail drug tar­gets

Seven years after striking up a major R&D alliance, AbbVie and Google-backed anti-aging specialist Calico are doubling down on their work with a joint, $1 billion commitment to continuing their work together. And they’re also beginning to offer some details on where this project is taking them in the clinic.

According to their statement, each of the two players is putting up $500 million more to keep the labs humming.

Look­ing to repli­cate Covid-19 suc­cess in neu­ro, BioN­Tech back­ers bet on AC Im­mune and its new­ly-ac­quired Parkin­son's vac­cine

The German billionaires behind BioNTech have found a new vaccine project to back.

Through their family office Athos Service, twin brothers Thomas and Andreas Strüngmann are leading a $25 million private placement into Switzerland’s AC Immune — which concurrently announced that it’s shelling out $58.7 million worth of stock to acquire Affiris’ portfolio of therapies targeting alpha-synuclein, including a vaccine candidate, for Parkinson’s disease.

Can­del gets busy IPO week mov­ing with down­sized raise as Ra­jiv Shuk­la's third SPAC goes pub­lic

Editor’s note: Interested in following biopharma’s fast-paced IPO market? You can bookmark our IPO Tracker here.

In a week that’s expected to see several biotechs price their IPOs, Candel Therapeutics got things kicked off Tuesday with a muted opener.

The company helmed by former GlaxoSmithKline vet Paul Peter Tak made its way to Nasdaq thanks to a $72 million raise, which was downsized by about 15% than originally anticipated, according to Renaissance Capital. Candel priced at $8 per share after initially seeking to launch in the $13 to $15 range.

Busi­ness­es and schools can man­date the use of Covid-19 vac­cines un­der EUAs, DOJ says

As public and private companies stare down the reality of the Delta variant, many are now requiring that their employees or students be vaccinated against Covid-19 prior to attending school or to returning or starting a new job. Claims that such mandates are illegal or cannot be used for vaccines under emergency use authorizations have now been dismissed.

Setting the record straight, the Department of Justice on Monday called the mandates legal in a new memo, even when used for people with vaccines that remain subject to EUAs.

BioN­Tech is spear­head­ing an mR­NA vac­cine de­vel­op­ment pro­gram for malar­ia, with a tech trans­fer planned for Africa

Flush with the success of its mRNA Covid-19 vaccine, BioNTech is now gearing up for one of the biggest challenges in vaccine development — which comes without potential profit.

The German mRNA pioneer says it plans to work on a jab for malaria, then transfer the tech to the African continent, where it will work with partners on developing the manufacturing ops needed to make this and other vaccines.
