Shreds of Tregs: French biotech wins Medicxi back­ing to kill the rogue im­muno­sup­pres­sive agent to fight can­cer

Ex­ist­ing CD25 drugs tend to thwart IL-2 sig­nal­ing, which is im­per­a­tive to shap­ing the body’s im­mune re­sponse. But a French drug de­vel­op­er thinks it has found a way to snuff out reg­u­la­to­ry T cells (known to con­tribute to the ear­ly es­tab­lish­ment and pro­gres­sion of tu­mors) by tar­get­ing CD25 with­out dis­turb­ing IL-2, and now has €18.5 mil­lion in its cof­fers to prove it.

The Parisian com­pa­ny, Alder­aan Biotech­nol­o­gy, is still very ear­ly in its jour­ney. The Se­ries A round of fund­ing from Ad­vent France Biotech­nol­o­gy (AFB) and Medicxi will be used to com­plete the pre­clin­i­cal de­vel­op­ment of its reg­u­la­to­ry T cell (Tregs) de­plet­ing CD25-spe­cif­ic an­ti­body and take it in­to the clin­ic by 2022.

An un­shack­led im­mune sys­tem can be as dan­ger­ous as a weak one. Tregs are de­signed to po­lice the im­mune sys­tem in­to work­ing as need­ed, but on the flip side, in the tu­mor mi­croen­vi­ron­ment, they con­tribute to dis­ease pro­gres­sion by sup­press­ing the body’s im­mune re­sponse. CD25 is not on­ly a mark­er for Tregs but is al­so key for the main­te­nance and func­tion of these cells. Mean­while, along with CD122 and CD132, CD25 forms the high-affin­i­ty re­cep­tor for in­ter­leukin(IL)-2, which is a growth fac­tor for T cells.

“What we’re do­ing with our an­ti­body is that we tar­get CD25 in a way that can kill reg­u­la­to­ry T cells in the tu­mor, so there is an elim­i­na­tion of those Tregs that are known to be im­muno­sup­pres­sive — but since our an­ti­bod­ies have the speci­fici­ty to spare the IL-2 re­cep­tor, it does not block IL-2 sig­nal­ing,” chief Ar­naud Fous­sat ex­plained in an in­ter­view with End­points News.

“This is crit­i­cal be­cause the old CD25 an­ti­bod­ies (such as Roche’s da­clizum­ab and No­var­tis’ Simulect) that have been de­vel­oped — they are block­ing IL-2, which means they are an­ti-in­flam­ma­to­ry by na­ture, and this is not good for on­col­o­gy.”

The ap­proach sounds a lot like the one tak­en by the British biotech, Tusk Ther­a­peu­tics, which was swal­lowed by Roche in 2018.

Alder­aan, which al­so has an even ear­li­er stage as­set de­signed to boost nat­ur­al killer (NK) cell cy­to­tox­ic ac­tiv­i­ty in can­cer, was found­ed in 2017. That year, it re­ceived €1.5 mil­lion in seed fund­ing in a round led by AFB.

Fol­low­ing SCO­TUS de­ci­sion to over­turn abor­tion pro­tec­tions, AG Gar­land says states can't ban the abor­tion pill

Following the Supreme Court’s historic decision on Friday to overturn Americans’ constitutional right to an abortion after almost 50 years, Attorney General Merrick Garland sought to somewhat reassure women that states will not be able to ban the prescription drug sometimes used for abortions.

Following the decision, the New England Journal of Medicine also published an editorial strongly condemning the reversal, saying it “serves American families poorly, putting their health, safety, finances, and futures at risk.”

AstraZeneca's new Evusheld direct to consumer campaign aims to reach more immunocompromised patients.

As­traZeneca de­buts first con­sumer cam­paign for its Covid-19 pro­phy­lac­tic Evusheld — and a first for EUA drugs

AstraZeneca’s first consumer ad for Evusheld is also a first for drugs that have been granted emergency use authorizations during the pandemic.

The first DTC ad for a medicine under emergency approval, the Evusheld campaign launching this week aims to raise awareness among immunocompromised patients — and spur more use.

Evusheld nabbed emergency authorization in December, however, despite millions of immunocompromised people looking for a solution and now more widespread availability of the drug.

Long­wood sets an­oth­er 'don't eat me' biotech in­to gear with help of for­mer Tril­li­um CEO Jan Skvar­ka

Jonathan Weissman and team are out with a cancer-fighting biotech riding the appetite for those so-called “don’t eat me” and “eat me” signals.

The scientific co-founder — alongside fellow Whitehead Institute colleague Kipp Weiskopf and Stanford biologist Michael Bassik — has launched DEM BioPharma with incubator Longwood Fund and a crop of other investors.

In all, the nascent, 10-employee biotech has $70 million to bankroll hematology- and solid tumor-based programs, including a lead asset that could enter human trials in two to three years, CEO David Donabedian told Endpoints News.

EU to launch vac­cine de­vel­op­ment and man­u­fac­tur­ing part­ner­ship with Latin Amer­i­can and Caribbean coun­tries

While European companies, including BioNTech, are focused on increasing vaccine access to African countries by setting up vaccine manufacturing facilities, the European Union is looking westward to Latin America and the Caribbean.

Speaking at a press conference with Spanish Prime Minister Pédro Sanchez, EU Commission president Ursula von der Leyen said that the EU is launching a new initiative for vaccines and medicines manufacturing in Latin America, to get drugs to Latin America and the Caribbean faster.

De­spite a slow start to the year for deals, PwC pre­dicts a flur­ry of ac­tiv­i­ty com­ing up

Despite whispers of a busy year for M&A, deal activity in the pharma space is actually down 30% on a semi-annualized basis, according to PwC’s latest report on deal activity. But don’t rule out larger deals in the second half of the year, the consultants said.

PwC pharmaceutical and life sciences consulting solutions leader Glenn Hunzinger expects to see Big Pharma companies picking up earlier stage companies to try and fill pipeline gaps ahead of a slew of big patent cliffs. Though a bear market continues to maul the biotech sector, Hunzinger said recent deals indicate that pharma companies are still paying above current trading prices.

VC firms take os­teo­poro­sis drug­mak­er Ra­dius Health pri­vate for al­most $900M

After attacks from activist investors and disappointing returns on share prices, Radius Health has now agreed to new ownership, a direction resulting in leaving the Nasdaq.

Radius Health, a biotech out of Massachusetts with one approved product in its arsenal, announced Thursday morning that it agreed to be acquired by two VC firms: Gurnet Point Capital and Patient Square Capital. The deal, worth around $890 million, will include debt assumption and the payout of $1 CVR per share for investors. And on top of that, OrbiMed is providing debt financing.
