Covid-19 roundup: Zy­dus Cadi­la sub­mits 3-dose vac­cine for reg­u­la­to­ry ap­proval; US do­nates Mod­er­na jabs to Pak­istan dur­ing short­age

In­dia’s sec­ond home-grown vac­cine could be ap­proved by reg­u­la­tors soon as Zy­dus Cadi­la an­nounced Thurs­day it has ap­plied for emer­gency use ap­proval with reg­u­la­tors in that na­tion.

The jab has demon­strat­ed ef­fi­ca­cy of 66.6%, and the com­pa­ny says stud­ies have shown it is safe for chil­dren be­tween the ages of 12 and 18 years old. The vac­cine’s piv­otal study was car­ried out in more than 50 clin­i­cal sites across In­dia dur­ing the peak of the coun­try’s sec­ond wave, which Cadi­la says reaf­firms the ef­fi­ca­cy against the Delta vari­ant.

Af­ter the third dose, sci­en­tists ob­served 100% ef­fi­ca­cy for mod­er­ate cas­es of the virus, Cadi­la said.

“This break­through marks a key mile­stone in sci­en­tif­ic in­no­va­tion and ad­vance­ment in tech­nol­o­gy,” Sharvil Pa­tel, the man­ag­ing di­rec­tor of Cadi­la Health­care, said in a state­ment. “As the first ever plas­mid DNA vac­cine for hu­man use, Zy­CoV-D has proven its safe­ty and ef­fi­ca­cy pro­file in our fight against COVID-19. The vac­cine when ap­proved will help not on­ly adults but al­so ado­les­cents in the 12 to 18 years age group.”

Zy­dus has al­so eval­u­at­ed a two-dose ver­sion of the vac­cine that us­es three mi­cro-dose por­tions.

Last year, Cadi­la an­nounced it was re­search­ing two vac­cine can­di­dates for Covid, one that us­es DNA to tar­get the vi­ral en­try mem­brane pro­tein, and an­oth­er that used a live at­ten­u­at­ed re­com­bi­nant measles virus.

US do­nates Mod­er­na jabs to Pak­istan dur­ing short­age

Pak­istan has re­ceived 2.5 mil­lion dos­es of Mod­er­na’s vac­cine Fri­day, US State De­part­ment spokesman Ned Price con­firmed on Twit­ter.

“This de­liv­ery un­der­scores our ties with the peo­ple of Pak­istan and our com­mit­ment to beat the pan­dem­ic glob­al­ly by vac­ci­nat­ing as many as pos­si­ble, as quick­ly as pos­si­ble,” the tweet said.

The de­liv­ery eas­es pres­sure on the cap­i­tal of Is­lam­abad in the midst of a vac­cine short­age.

The vac­cines were de­liv­ered in part­ner­ship with CO­V­AX, UNICEF and the Pak­istani gov­ern­ment, the As­so­ci­at­ed Press re­port­ed. The do­na­tion was part of the 80 mil­lion dos­es the US has pledged to share with the world.

Ger­many locks in dos­es for 2022 ahead of any pos­si­ble vari­ants

The Ger­man gov­ern­ment will spend big mon­ey to se­cure an­oth­er 204 mil­lion dos­es of vac­cines, and 50.1 mil­lion of those dos­es will be from J&J and Mod­er­na, Reuters re­ports. The spree is an at­tempt to avoid pro­duc­tion bot­tle­necks and pro­tec­tion against pos­si­ble vari­ants.

The Robert Koch In­sti­tute has ad­vised the gov­ern­ment that there should be suf­fi­cient mR­NA vac­cines avail­able to ful­ly cov­er the coun­try’s pop­u­la­tion, but al­ter­na­tives should be brought on in case of any “un­fore­seen prob­lems,” ac­cord­ing to Reuters.

A to­tal of 70 mil­lion com­bined dos­es will come from Sanofi, No­vavax and Val­ne­va. Near­ly 85 mil­lion of the dos­es will come from Pfiz­er/BioN­Tech, as they are al­ready con­tract­ed through the EU’s pro­cure­ment scheme.

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.

Mi­rati's KRAS drug looks like the fa­vorite in colon can­cer with new da­ta, putting the pres­sure square on Am­gen

With Amgen already providing proof-of-concept for KRAS inhibitors with its sotorasib, Mirati Therapeutics is piecing together a follow-up effort in lung cancer with data it thinks are superior. But in colon cancer, where solo sotorasib has turned in a dud, Mirati may now have a strong case for superiority.

Mirati’s adagrasib, dosed solo or in combination with chemotherapy cetuximab, showed response rates grater than sotorasib solo  and as part of combination study in a similar patient population also revealed this week at #ESMO21. Mirati’s data were presented as part of a cohort update from the Phase II KRYSTAL-1 study testing adagrasib in a range of solid tumors harboring the KRAS-G12C mutation.

The best of the rest: High­lights from the be­low-the-fold pre­sen­ta­tions at #ES­MO21

This year’s ESMO Congress has had a major focus on Big Pharma drugs — most notably candidates from Merck and AstraZeneca — but there have also been updates from smaller biotechs with data looking to challenge the big-name drugmakers.

Today, we’re highlighting some of the data releases that flew under the radar at #ESMO21 — whether from early-stage drugs looking to make a mark or older stalwarts with interesting follow-up data.

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.
