Af­ter ear­ly hic­cups in man­u­fac­tur­ing, Ad­verum out­lines plans for com­mer­cial gene ther­a­py plant in North Car­oli­na hub

Af­ter some ear­ly hic­cups in its man­u­fac­tur­ing pro­ce­dures for its gene ther­a­py drug tar­get­ing wet age-re­lat­ed mac­u­lar de­gen­er­a­tion, Cal­i­for­nia biotech Ad­verum has ad­dressed those con­cerns and is prim­ing the pump for a com­mer­cial launch.

The oc­u­lar and oth­er rare dis­ease-fo­cused gene ther­a­py com­pa­ny will in­vest $80 mil­lion in a new cGMP man­u­fac­tur­ing fa­cil­i­ty in North Car­oli­na’s bustling Re­search Tri­an­gle Park that by 2023 will be ready to man­u­fac­ture com­mer­cial sup­ply of AD­VM-022, Ad­verum’s in­trav­it­re­al ther­a­peu­tic, the com­pa­ny said Thurs­day.

The 174,000 square-foot fa­cil­i­ty will in­clude four 1,000-liter biore­ac­tors, with space for fu­ture ex­pan­sion, and will cre­ate more than 200 jobs. In ad­di­tion to its $80 mil­lion in­vest­ment, Ad­verum will gain up to $9 mil­lion in North Car­oli­na state and lo­cal in­cen­tives.

“Our new in-house com­mer­cial man­u­fac­tur­ing fa­cil­i­ty sets the foun­da­tion of our over­all man­u­fac­tur­ing strat­e­gy,” An­gela Thedin­ga, Ad­verum’s chief tech­nol­o­gy of­fi­cer, said in a state­ment. “Our new site will pro­vide ded­i­cat­ed com­mer­cial sup­ply, while we con­tin­ue to lever­age CMO part­ner­ships for flex­i­ble clin­i­cal and ad­di­tion­al com­mer­cial sup­ply.”

In 2020, Phase I tri­al da­ta from AD­VM-022 start­ed to turn a cor­ner af­ter some weak read­outs in the past. In­ves­ti­ga­tors in May re­port­ed that two of three co­horts con­tin­ued to re­spond to treat­ment, with the ma­jor­i­ty still free of the need for res­cue in­jec­tions, while the third co­hort ex­pe­ri­enced few­er side ef­fects than oth­er an­ti-VEGF ther­a­peu­tics.

Lau­rent Fis­ch­er

The year 2019 was more dif­fi­cult for the biotech. In April of that year, the FDA im­posed a clin­i­cal hold on the ap­pli­ca­tion to test AD­VM-022 in hu­mans, ask­ing Ad­verum for more da­ta on the chem­istry, man­u­fac­tur­ing and con­trol process, End­points News re­port­ed. The hold was lift­ed short­ly af­ter.

Then in Sep­tem­ber, Ad­verum re­vealed da­ta that in­di­cat­ed pa­tients with AMD saw their vi­sion de­te­ri­o­rate when treat­ed with AD­VM-022, de­spite signs that the treat­ment was im­prov­ing reti­nal anato­my. Those pa­tients who saw a vi­sion de­te­ri­o­ra­tion lost vi­su­al acu­ity by two let­ters on av­er­age in a 90% con­fi­dence in­ter­val of -9.1 let­ters to +5.1 let­ters, the com­pa­ny re­port­ed from the 24-week OP­TIC tri­al.

In late 2019, the biotech al­so aban­doned de­vel­op­ment of its then-lead ex­per­i­men­tal drug, AD­VM-043, for treat­ing A1AT de­fi­cien­cy.

In a press re­lease an­nounc­ing Ad­verum’s new fa­cil­i­ty, CEO Lau­rent Fis­ch­er was down­right bull­ish on the com­pa­ny’s fu­ture.

“We are build­ing a team with ex­cep­tion­al AAV-gene ther­a­py ex­pe­ri­ence and we are thrilled to join the high­ly-skilled and di­verse North Car­oli­na biotech com­mu­ni­ty,” he said. “This state-of-the-art fa­cil­i­ty will sup­port our com­mer­cial­iza­tion of AD­VM-022, the po­ten­tial first mass mar­ket­ed gene ther­a­py for wet AMD and DME.”

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.

Skin tu­mors in mice force Pro­tag­o­nist to halt lead pro­gram, crush­ing stock

Protagonist Therapeutics just can’t catch a break.

Six months after the Newark, CA-based biotech unveiled grand plans to launch its lead candidate for blood disorders into a Phase III trial, the FDA has slapped the program with a clinical hold. The halt — which applies to all trials involving the candidate, rusfertide — comes after skin tumors were discovered in mice treated with the drug, according to Protagonist.

Chi­nese biotech Ever­est signs $550M+ li­cens­ing deal for BTK in­hibitors on heels of Covid-19 pact

Everest Medicines is on a roll with two licensing deals in one week.

The Shanghai-based biotech has paid Sinovent and SinoMab $12 million upfront for the rights to a BTK inhibitor for renal diseases, the company announced Thursday. The deal comes just days after Everest came away with rights to a Covid-19 vaccine in China, Taiwan, Singapore, Thailand and Indonesia.

Everest will pay Sinovent and SinoMab up to $549 million in milestone payments and royalties. The agreement includes tech transfer of Sinovent and SinoMab’s manufacturing process for the candidate, named XNW1011.
