On­colyt­ic con­tender Turn­stone bags a $41M B round to push a suc­ces­sor for Im­ly­g­ic

Turn­stone CEO Sam­my Farah

Ever since Am­gen made it to the mar­ket with a pi­o­neer­ing on­colyt­ic virus can­cer ther­a­py called Im­ly­g­ic (T-Vec), which it bagged in a bil­lion-dol­lar deal to ac­quire BioVex, you could see a wave of biotech com­peti­tors form­ing — look­ing to do the same ther­a­peu­tic job bet­ter.

To­day, Cana­da’s Turn­stone Bi­o­log­ics takes an­oth­er big step in that march, bag­ging a $41.4 mil­lion Se­ries B that will go a long way to demon­strat­ing whether it has a re­al con­tender for that mar­ket, while fu­el­ing ad­di­tion­al work in build­ing the pipeline.

“The raise comes pret­ty quick­ly af­ter our ini­tial Se­ries A,” says CEO Sam­my Farah. “What re­al­ly drove our de­sire to bring in more fund­ing, we want­ed to ex­pand and ac­cel­er­ate clin­i­cal de­vel­op­ment pro­grams, do much more in the clin­ic and do much more in the very near term.”

That means wrap­ping an on­go­ing Phase I/II study for the lead pro­gram for an en­gi­neered virus, with a sec­ond tri­al ready to launch lat­er this year that will in­clude one of the ap­proved check­point in­hibitors (they’re not say­ing which one, for now). Two more pro­grams will launch next year, bring­ing Turn­stone up to four ac­tive clin­i­cal ef­forts.

Turn­stone has been work­ing with a trio of found­ing sci­en­tists in its cor­ner, led by John Bell.

“I think we are quite unique,” Bell tells me. Their ther­a­py en­codes a tu­mor anti­gen de­signed to spur an im­mune re­sponse while al­so stim­u­lat­ing pe­riph­er­al im­mu­ni­ty, of­fer­ing an on­colyt­ic to pen­e­trate and de­stroy can­cer cells and a can­cer vac­cine at the same time. And like oth­er ri­val biotechs in the field, in­clud­ing PsiOxus, the biotech be­lieves that sys­temic de­liv­ery of their drug will make a big dif­fer­ence for pa­tients.

“The oth­ers,” he says about the com­pe­ti­tion, “can’t gen­er­ate a po­tent vac­cine ef­fect.” The check­point in­hibitor, which takes the brakes off the im­mune sys­tem as the vac­cine ap­plies the gas, makes for a nat­ur­al com­bi­na­tion ap­proach, as the lead­ers in that field work hard to pur­sue hun­dreds of new com­bi­na­tion ap­proach­es.

Bell al­so has been work­ing on new strate­gies de­signed to match next-gen drugs specif­i­cal­ly for cer­tain tu­mors. That may call for new and im­proved on­colyt­ic ap­proach­es while al­so ex­am­in­ing which of the check­points are more suit­able for cer­tain tu­mors.

“In ad­di­tion to the clin­i­cal pro­gram we talked about be­fore,” adds Farah, “we’re al­so look­ing at some ex­cit­ing ar­eas, like neoanti­gen per­son­al­ized vac­cines. Our tech­nol­o­gy is very suit­ed to per­son­al­ized can­cer field.”

Or­biMed led this round, with an ex­pand­ed syn­di­cate that in­cludes new in­vestor F-Prime Cap­i­tal Part­ners and ex­ist­ing in­vestors FAC­IT and Ver­sant Ven­tures, which led Turn­stone’s Se­ries A.

What Will it Take to Re­al­ize the Promise and Po­ten­tial of Im­mune Cell Ther­a­pies?

What does it take to get to the finish line with a new cancer therapy – fast? With approvals in place and hundreds of immune cell therapy candidates in the pipeline, the global industry is poised to create a fundamental shift in cancer treatments towards precision medicine. At the same time, unique challenges associated with cell and process complexity present manufacturing bottlenecks that delay speed to market and heighten cost of goods sold (COGS) — these hurdles must be overcome to make precision treatments an option for every cancer patient. This series of articles highlights some of the key manufacturing challenges associated with the production of cell-based cancer therapies as well as the solutions needed to transcend them. Automation, process knowledge, scalability, and assured supply of high-quality starting material and reagents are all critical to realizing the full potential of CAR-based therapies and sustaining the momentum achieved in recent years. The articles will highlight leading-edge technologies that incorporate these features to integrate across workflows, accelerate timelines and reduce COGS – along with how these approaches are enabling the biopharmaceutical industry to cross the finish line faster with new treatment options for patients in need.

The biggest ques­tions fac­ing gene ther­a­py, the XLMTM com­mu­ni­ty, and Astel­las af­ter fourth pa­tient death

After three patients died last year in an Astellas gene therapy trial, the company halted the study and began figuring out how to safely get the program back on track. They would, executives eventually explained, cut the dose by more than half and institute a battery of other measures to try to prevent the same thing from happening again.

Then tragically, Astellas announced this week that the first patient to receive the new regimen had died, just weeks after administration.

Chaot­ic ad­comm sees Pfiz­er/BioN­Tech boost­ers re­ject­ed for gen­er­al pop­u­la­tion, but rec­om­mend­ed for old­er and high-risk pop­u­la­tions

With just days before President Joe Biden’s Covid-19 booster rollout is set to go into effect, an FDA advisory committee appeared on the verge of not recommending boosters for anyone in the US before a last-minute change of wording laid the groundwork for older adults to have access to a third dose.

The FDA’s adcomm on Vaccines and Related Biological Products (VRBPAC) roundly rejected Pfizer/BioNTech booster shots for all individuals older than 16 by a 16-2 vote Friday afternoon. Soon after, however, the agency posed committee members a new question limiting booster use to the 65-and-older population and individuals at high risk of disease due to occupational exposure or comorbidities.

As­traZeneca, Dai­ichi Sanky­o's ADC En­her­tu blows away Roche's Kad­cy­la in sec­ond-line ad­vanced breast can­cer

AstraZeneca and Japanese drugmaker Daiichi Sankyo think they’ve struck gold with their next-gen ADC drug Enhertu, which has shown some striking data in late-stage breast cancer trials and early solid tumor tests. Getting into earlier patients is now the goal, starting with Enhertu’s complete walkover of a Roche drug in second-line breast cancer revealed Saturday.

Enhertu cut the risk of disease progression or death by a whopping 72% (p=<0.0001) compared with Roche’s ADC Kadcyla in second-line unresectable and/or metastatic HER2-positive breast cancer patients who had previously undergone treatment with a Herceptin-chemo combo, according to interim data from the Phase III DESTINY-Breast03 head-to-head study presented at this weekend’s #ESMO21.

Mer­ck­'s Keytru­da un­corks full da­ta on lat­est ad­ju­vant win — this time in melanoma — adding bricks to ear­ly can­cer wall

In recent months, the battle for PD-(L)1 dominance has spilled over into early cancer with Merck’s Keytruda and Bristol Myers Squibb’s Opdivo all alone on the front lines. Keytruda now has another shell in its bandolier, and it could spell a quick approval.

Keytruda cut the risk of relapse or death by 35% over placebo (p=0.00658) in high-risk, stage 2 melanoma patients who had previously undergone surgery to remove their tumors, according to full data from the Phase III KEYNOTE-716 presented Saturday at #ESMO21.

Mer­ck flesh­es out Keytru­da win in first-line cer­vi­cal can­cer, adding more fire­pow­er to its ear­ly can­cer push

Merck has worked hard to bring its I/O blockbuster Keytruda into earlier and earlier lines of therapy, and now the wonder drug appears poised to make a quick entry into early advanced cervical cancer.

A combination of Keytruda and chemotherapy with or without Roche’s Avastin cut the risk of death by 33% over chemo with or without Avastin (p=<0.001) in first-line patients with persistent, recurrent or metastatic cervical cancer, according to full data from the Phase III KEYNOTE-826 study presented Saturday at #ESMO21.

EQRx, CStone un­furl full lung can­cer da­ta for PD-L1 drug in what the part­ners are call­ing a first

As a self-stylized drug pricing disruptor, EQRx has high hopes for its lead PD-(L)1 to offer proof of concept for the entire business model. After touting a win back in May, the biotech is back with full data in lung cancer that could back up an approval.

Patients dosed with EQRx and CStone Pharmaceuticals’ sugemalimab posted median progression-free survival of 9 months compared with 5.8 months for patients given placebo (p=0.0026), according to full data from the Phase III GEMSTONE-301 study in Stage III non-small cell lung cancer set to be presented at this weekend’s #ESMO21.

As­traZeneca touts Imfinzi im­munother­a­py com­bos for lung can­cer in push to dri­ve PD-L1 drug up­take

Facing the big dogs in the PD-(L)1 space, AstraZeneca has taken its own contender Imfinzi into blockbuster territory in its four years on the market but sees even bigger things for the drug. Combinations could be the key, and early results from a mid-stage test are adding some fuel to that strategy.

Imfinzi combined with one of two investigational immunotherapies — a CD73 antibody dubbed oleclumab or an Innate’s anti-NGK2a named monalizumab — topped Imfinzi alone in terms of overall response and progression-free survival in patients with stage III non-small cell lung cancer whose tumors had not worsened during concurrent chemoradiation, according to interim data from the Phase II COAST trial set to be presented at #ESMO21.
