Pfiz­er's CD22-tar­get­ed can­cer drug in­o­tuzum­ab wins an ac­cel­er­at­ed OK at FDA

Pfiz­er’s armed an­ti­body in­o­tuzum­ab ozogam­icin — held up as a top on­col­o­gy con­tender at the phar­ma gi­ant — has just won an ac­cel­er­at­ed ap­proval at the FDA for re­lapsed or re­frac­to­ry B-cell pre­cur­sor acute lym­phoblas­tic leukemia.

Liz Bar­rett

The drug is the first to reach the mar­ket which is de­signed to bind to the CD22 anti­gen on B-cells, where it then goes in­to the can­cer cell to de­liv­er a cy­to­tox­ic pay­load of calicheam­icin, de­stroy­ing the cell. Pfiz­er has made a strong push on the can­cer front in re­cent years, as wit­nessed by its rapid-fire ap­proval for its check­point in­hibitor avelum­ab, part­nered with Mer­ck KGaA, and a $14 bil­lion buy­out deal for Medi­va­tion.

In­ves­ti­ga­tors tracked a com­plete re­sponse rate of 81% for this drug — which will now be sold as Be­spon­sa — com­pared to 29% in a chemo arm. And that has some an­a­lysts pro­ject­ing peak sales of around $2 bil­lion, a sol­id hit for the phar­ma gi­ant’s on­col­o­gy di­vi­sion.

The ap­proval — com­ing af­ter the FDA of­fered a 6-month pri­or­i­ty re­view sched­ule — marks a big come­back for Pfiz­er on this drug, which flopped in a Phase III tri­al for non-Hodgkin’s lym­phoma four years ago,

Said Liz Bar­rett, glob­al pres­i­dent, Pfiz­er On­col­o­gy:

“Be­spon­sa will help ad­dress a sig­nif­i­cant need for new treat­ment op­tions in B-cell acute lym­phoblas­tic leukemia, and may help more pa­tients reach stem cell trans­plant, which pro­vides the best chance for long term re­mis­sion. We’re proud to build on our con­tin­ued com­mit­ment to pa­tients with hema­to­log­ic ma­lig­nan­cies, and will con­tin­ue our work to find new treat­ments in acute lym­phoblas­tic leukemia and oth­er blood can­cers.”

Biotech Half­time Re­port: Af­ter a bumpy year, is biotech ready to re­bound?

The biotech sector has come down firmly from the highs of February as negative sentiment takes hold. The sector had a major boost of optimism from the success of the COVID-19 vaccines, making investors keenly aware of the potential of biopharma R&D engines. But from early this year, clinical trial, regulatory and access setbacks have reminded investors of the sector’s inherent risks.

RBC Capital Markets recently surveyed investors to take the temperature of the market, a mix of specialists/generalists and long-only/ long-short investment strategies. Heading into the second half of the year, investors mostly see the sector as undervalued (49%), a large change from the first half of the year when only 20% rated it as undervalued. Around 41% of investors now believe that biotech will underperform the S&P500 in the second half of 2021. Despite that view, 54% plan to maintain their position in the market and 41% still plan to increase their holdings.

No­var­tis de­vel­op­ment chief John Tsai: 'We go deep in the new plat­form­s'

During our recent European Biopharma Summit, I talked with Novartis development chief John Tsai about his experiences over the 3-plus years he’s been at the pharma giant. You can read the transcript below or listen to the exchange in the link above.

John Carroll: I followed your career for quite some time. You’ve had more than 20 years in big pharma R&D and you’ve obviously seen quite a lot. I really was curious about what it was like for you three and a half years ago when you took over as R&D chief at Novartis. Obviously a big move, a lot of changes. You went to work for the former R&D chief of Novartis, Vas Narasimhan, who had his own track record there. So what was the biggest adjustment when you went into this position?

Roche's Tecen­triq cross­es the fin­ish line first in ad­ju­vant lung can­cer, po­ten­tial­ly kick­ing off gold rush

While falling behind the biggest PD-(L)1 drugs in terms of sales, Roche has looked to carve out a space for its Tecentriq with a growing expertise in lung cancer. The drug will now take an early lead in the sought-after adjuvant setting — but competitors are on the way.

The FDA on Friday approved Tecentriq as an adjuvant therapy for patients with Stage II-IIIA non small cell lung cancer with PD-(L)1 scores greater than or equal to 1, making it the first drug of its kind approved in an early setting that covers around 40% of all NSCLC patients.

As­traZeneca on­col­o­gy R&D chief Su­san Gal­braith: 'Y­ou're go­ing to need or­thog­o­nal com­bi­na­tion­s'

 

Earlier in the week we broadcast our 4th annual European Biopharma Summit with a great lineup of top execs. One of the one-on-one conversations I set up was with Susan Galbraith, the oncology research chief at AstraZeneca. In a wide-ranging discussion, Galbraith reviewed the cancer drug pipeline and key trends influencing development work at the pharma giant. You can watch the video, above, or stick with the script below. — JC

Imfinzi/treme­li­mum­ab com­bo scores As­traZeneca an­oth­er OS win — this time in liv­er can­cer

Is the tide turning on AstraZeneca’s battered PD-L1/CTLA4 combo?

A single priming dose of the experimental tremelimumab, followed by Imfinzi every four weeks, beat Nexavar (sorafenib) in helping a group of liver cancer patients live longer in a Phase III study, the company reported, meeting the primary endpoint.

Specifically, the two drugs extended overall survival for patients with unresectable hepatocellular carcinoma who had not received prior systemic therapy and were not eligible for localized treatment.

Amit Etkin, Alto Neuroscience CEO (Alto via Vimeo)

A star Stan­ford pro­fes­sor leaves his lab for a start­up out to re­make psy­chi­a­try

About five years ago, Amit Etkin had a breakthrough.

The Stanford neurologist, a soft-spoken demi-prodigy who became a professor while still a resident, had been obsessed for a decade with how to better define psychiatric disorders. Drugs for depression or bipolar disorder didn’t work for many patients with the conditions, and he suspected the reason was how traditional diagnoses didn’t actually get at the heart of what was going on in a patient’s brain.

Rahul Singhvi, Resilience CEO

A Bob Nelsen start­up turns to Har­vard to help sharp­en its tech, in­spir­ing first spin­out

One of Bob Nelsen’s latest projects is headed to Harvard.

Resilience, a company started with the goal of establishing itself as a “one-stop-shop” for companies looking to scale manufacturing, including for hard-to-develop cell and gene therapies, is less than a year old. Friday, it announced a five-year R&D deal with Harvard University that includes $30 million to develop biologics, including vaccines, nucleic acids and cell and gene therapies.

Tillman Gerngross, Adagio CEO

Q&A: Till­man Gern­gross ex­plains why his Covid mAb will have an edge over an al­ready crowd­ed field

If anyone knows about monoclonal antibodies, it’s serial entrepreneur, Adimab CEO, and Dartmouth professor of bioengineering Tillman Gerngross.

Even the name of Gerngross’ new antibody startup Adagio Therapeutics is meant to reflect his vision behind the development of his Covid-19 mAb: slowly, he said, explaining that “everyone else, whether it’s Regeneron, Lilly, or AstraZeneca, Vir, they all valued speed over everything.”
