Hahn stress­es im­por­tance of da­ta, RWE in first all-hands meet­ing

FDA Com­mis­sion­er Stephen Hahn ad­dressed FDA staffers in an all-hands meet­ing for the first time on Thurs­day, ex­plain­ing how he wants to do more with re­al-world ev­i­dence (RWE), which has been a con­tro­ver­sial sub­ject.

While not­ing that the FDA is op­er­at­ing in a time of “un­sur­passed sci­en­tif­ic and tech­no­log­i­cal in­no­va­tion,” Hahn called to un­leash the pow­er of da­ta and “to at­tain more and bet­ter da­ta.” His com­ments build up­on the agency’s tech­nol­o­gy mod­ern­iza­tion plan un­veiled last Sep­tem­ber.

“By har­ness­ing this pow­er, we can im­prove our reg­u­la­to­ry de­ci­sion-mak­ing and more ef­fec­tive­ly con­nect to­day’s ground­break­ing sci­en­tif­ic dis­cov­er­ies with the rapid de­vel­op­ment and ap­proval of new prod­ucts. We can al­so in­crease the knowl­edge pa­tients and con­sumers have to make in­formed de­ci­sions about FDA-reg­u­lat­ed prod­ucts,” he said.

Hahn al­so con­tin­ued to push the agen­da of his pre­de­ces­sor, Scott Got­tlieb, who re­leased an RWE frame­work in De­cem­ber 2018. Al­though the agency has on­ly used RWE in lim­it­ed amounts so far.

“Specif­i­cal­ly, I be­lieve there is great promise in the ef­fec­tive use and in­te­gra­tion of pa­tient-lev­el da­ta or re­al-world ev­i­dence such as elec­tron­ic health records, clin­i­cal tri­als, med­ical stud­ies, and pa­tient reg­istries,” Hahn said.

For­mer FDA Com­mis­sion­ers Robert Califf, Mark Mc­Clel­lan and An­drew von Es­chen­bach al­so of­fered their rec­om­men­da­tions to ex­pand the use of RWE in reg­u­la­to­ry and pay­ment de­ci­sion-mak­ing. But ques­tions on the ap­plic­a­bil­i­ty of RWE linger. A re­cent study in JA­MA Open Net­work found that re­al-world da­ta (RWD) could on­ly be used to fea­si­bly repli­cate 15% of high-pro­file clin­i­cal tri­als con­duct­ed in the US in 2017.

For­mer FDA Com­mis­sion­er Rob Califf al­so said RWE and RWD can in­clude ran­dom­iza­tion and oth­er meth­ods to en­able causal in­fer­ence. “We wor­ried at the time that the terms RWD & RWE would be hi­jacked to fos­ter low qual­i­ty re­search. This must be fought, be­cause well done RWD & RWE with prop­er use of meth­ods for causal in­fer­ence is HIGH­ER qual­i­ty & more gen­er­al­iz­able,” Califf wrote on Twit­ter.

Hahn al­so stressed the need to build up­on the FDA’s Pa­tient-Fo­cused Drug De­vel­op­ment ini­tia­tive so “con­sumers may be even more in­formed and aware about the en­tire life­cy­cle of prod­ucts we reg­u­late in or­der to live more healthy and pro­duc­tive lives.”

And per­haps as a re­sponse to cri­tiques of the agency’s re­cent speedy ap­provals of new drugs, Hahn said the agency needs to “main­tain the vi­tal bal­ance be­tween the speedy ap­proval of new prod­ucts and the in­tegri­ty of the da­ta and the process it­self.”Ed­i­tor’s Note:

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.

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.

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 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.

Am­gen rolls out da­ta for KRAS in­hibitor com­bo study in col­orec­tal can­cer, hop­ing to move on from ug­ly ear­ly re­sults

With the first win for its KRAS inhibitor sotorasib in hand, Amgen is pushing ahead with an aggressive clinical plan to capitalize on its first-to-market standing. The drugmaker thinks combinations — in-house or otherwise — could offer a path forward, and one early readout from that strategy is bearing fruit.

A combination of Amgen’s sotorasib and its EGFR inhibitor Vectibix posted an overall response rate of 27% in 26 patients with advanced colorectal cancer (CRC) with the KRAS-G12C mutation, according to data from the larger Phase Ib/II CODEBREAK 101 study set to present at this weekend’s virtual ESMO Congress.

Eu­ro­pean study finds that Gilead­'s Covid-19 an­tivi­ral remde­sivir shows no clin­i­cal ben­e­fit

Gilead’s remdesivir — or Veklury, as it’s marketed in the US — raked in around $2.8 billion last year as the only FDA-approved antiviral to treat Covid-19. But new data from a European study suggest the drug, which has been given to about half of hospitalized Covid patients in the country, has no actual benefit.

The open-label DisCoVeRy trial enrolled Covid-19 patients across 48 sites in Europe to test a handful of treatments, including remdesivir, lopinavir–ritonavir, lopinavir–ritonavir and interferon beta-1a, and hydroxychloroquine. To participate, patients had to show symptoms for seven days and require oxygen support. A total of 429 patients were randomized to receive remdesivir plus standard of care, while 428 were assigned to standard of care alone.

Gri­fols drops $1B on Ger­man hold­ing com­pa­ny in con­tin­ued plas­ma push

One Spanish biotech is beefing up its plasma therapy operations, and on Friday, it announced that it’s doing so in a billion-dollar deal.

Grifols is now the largest shareholder of Biotest, a company valued at more than $1.8 billion. By teaming up, the two will try to increase the number of plasma therapies available and increase patient access around the world, Grifols said in a press release.

The company did so by acquiring holding company Tiancheng Pharmaceutical, the Germany-based owner of nearly 90% of Biotest shares, for nearly $1.27 billion. Grifols now owns nearly 90% of Biotest voting rights and almost 45% of the total share capital of Biotest.

Covid-19 roundup: FDA re­veals boost­er ad­comm ques­tion; Eli Lil­ly's an­ti­body cock­tail cleared for pre­ven­tion

The FDA released briefing documents this week from the agency and Pfizer each outlining their arguments for today’s Covid-19 booster shot adcomm, but one thing conspicuously missing was the question on which panel members would be voting. But late Thursday night, regulators published that question.

Adcomm members will be asked whether or not the safety and efficacy data from Pfizer/BioNTech’s original Phase III study “support approval” of a booster shot at least six months after the second dose in individuals older than 16. The question notably excludes the real-world data from Israel and other analyses that Pfizer and the Biden administration had said would be a centerpiece of their arguments for boosters.

A Pfiz­er part­ner wel­comes ex-ADC Ther­a­peu­tics CMO Jay Fein­gold to the team; Amid tough sled­ding, Im­muno­vant choos­es Eli Lil­ly alum as CFO

→ Last week we told you about the CMO revolving door at ADC Therapeutics, as Joseph Camardo replaced the departing Jay Feingold. The next opportunity for Feingold in the CMO slot has opened up at antibody-drug conjugate and mAb developer Pyxis Oncology, which has added several new execs and scientific advisory board members in recent months, including ex-Immunovant CFO Pamela Yanchik Connealy. Before his tenure at ADC, Feingold was Daiichi Sankyo’s VP of US medical affairs and chairman of the Global Medical Affairs Oversight Committee. Within weeks in March, Pyxis struck a licensing deal with Pfizer for two of its ADCs and raked in $152 million from a Series B round.

Take­da scores a win for a rare type of lung can­cer, gear­ing up for a show­down with J&J

Four months after J&J’s infused drug Rybrevant scored the industry’s first win in a rare type of non-small cell lung cancer (NSCLC), Takeda is following up with an oral option for the small but desperate patient population.

The FDA granted an accelerated approval to Takeda’s oral TKI inhibitor Exkivity (mobocertinib) in metastatic NSCLC patients with EGFR exon 20 gene mutations who had previously undergone platinum-based chemotherapy, the company announced on Wednesday.
