J&J, GV back a new sin­gle-cell ap­proach for tack­ling in­flam­ma­to­ry dis­eases and hack­ing the tu­mor mi­croen­vi­ron­ment

Most biotechs try­ing to tack­le in­flam­ma­to­ry dis­or­ders like IBD or at­tempt­ing to boost the po­ten­cy of im­munother­a­pies for can­cer have fo­cused, log­i­cal­ly, on tar­get­ing, block­ing or redi­rect­ing im­mune cells.

J&J, GV and North­pond Ven­tures, though, are back­ing a com­pa­ny with a dif­fer­ent ap­proach, seed­ing UK-based Mestag Ther­a­peu­tics with $45 mil­lion to ex­plore whether drug­ging fi­brob­lasts — the cells that cre­ate and form the body’s con­nec­tive tis­sue — can help get at the un­der­ly­ing mech­a­nisms that let tu­mors evade the im­mune sys­tems and keep pa­tients with dis­eases like IBD in a con­stant state of in­flam­ma­tion.

“There’s lots of ac­tiv­i­ty look­ing at the im­mune cells: B cells, T cells, mast cells,” Mestag CEO Su­san Hill told End­points News. “But ac­tu­al­ly the sur­round­ing tis­sues and the role they might be play­ing are of­ten over­looked.”

Mestag builds off work at Har­vard, The Broad In­sti­tute, Cold Spring Har­bor and else­where that used a rel­a­tive­ly new tech­nol­o­gy, sin­gle-cell se­quenc­ing, to dis­cov­er dif­fer­ent sub­types of fi­brob­lasts in dis­eased tis­sue and show how cer­tain ones were im­pli­cat­ed in dis­ease. Har­vard’s Soumya Ray­chaud­huri and Ox­ford’s Chris Buck­ley, along­side Mark Coles and Michael Bren­ner at Brigham and Women’s Hos­pi­tal, found fi­brob­lasts dri­ving in­flam­ma­tion in arthri­tis. At Cold Spring Har­bor, David Tu­ve­son found fi­brob­lasts im­pli­cat­ed in pan­cre­at­ic can­cer.

Fi­brob­lasts, they showed, don’t sim­ply form the struc­ture of tis­sues. They al­so se­crete sig­nals that com­mu­ni­cate with oth­er cells and par­tic­u­lar­ly im­mune cells, di­rect­ing them on where to go.

Hill said Mestag will try to de­vel­op drugs that can ef­fec­tive­ly re­pro­gram a sub­set of fi­brob­lasts around a tu­mor so that the cells go from im­mune-sup­pres­sive to im­mune-ac­ti­vat­ing. The goal would be to use the drug in com­bi­na­tion with check­point in­hibitors, one of a pha­lanx of ap­proach­es re­searchers have de­ployed in an ef­fort to boost im­munother­a­pies or ap­ply them to more pa­tients.

The com­pa­ny will sim­i­lar­ly try to change the sig­nals com­ing from fi­brob­lasts im­pli­cat­ed in in­flam­ma­tion. Hill said she be­lieved the com­pa­ny could get at a more un­der­ly­ing mech­a­nism for in­flam­ma­tion than cur­rent ther­a­pies that try to sup­press the im­mune sys­tem.

“Of­ten in many in­flam­ma­to­ry in­di­ca­tions, the top ther­a­peu­tic ap­proach­es are tar­get­ing im­mune ef­fec­tor cells. But when you look at the clin­i­cal da­ta, the ma­jor­i­ty of pa­tients nev­er re­al­ly reach prop­er clin­i­cal re­mis­sion,” Hill said. “So there must be some­thing” con­tin­u­ing to dri­ve dis­ease.

Mestag an­nounced an ini­tial seed in April, with $11 mil­lion from J&J and SV Health In­vestors. They an­nounced a $34 mil­lion ex­ten­sion Mon­day led by For­bion and joined by GV and North­pond along­side the pre­vi­ous two back­ers.

In ad­di­tion to pro­vid­ing ear­ly in­vest­ment, J&J al­so inked a part­ner­ship the now 25-per­son com­pa­ny.  The two will use sin­gle-cell analy­sis and oth­er tools to find nov­el tar­gets for in­flam­ma­to­ry dis­eases.

Those ef­forts re­main ear­ly stage, though. Hill said the com­pa­ny is still in dis­cov­ery and would not be in the clin­ic for at least a cou­ple of years.

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.

How to col­lect and sub­mit RWD to win ap­proval for a new drug in­di­ca­tion: FDA spells it out in a long-await­ed guid­ance

Real-world data is messy. There can be differences in the standards used to collect different types of data, differences in terminologies and curation strategies, and even in the way data is exchanged.

While acknowledging this somewhat controlled chaos, the FDA is now explaining how biopharma companies can submit study data derived from real-world data (RWD) sources in applicable regulatory submissions, including new drug indications.

Pfiz­er throws its weight be­hind LNP play­er eye­ing mR­NA treat­ments for CF, PCD

David Lockhart did not see the meteoric rise of messenger RNA and lipid nanoparticles coming.

Thanks to the worldwide fight against Covid-19, mRNA — the genetic code that can be engineered to turn the body into a mini protein factory — and LNPs, those tiny bubbles of fat carrying those instructions, have found their way into hundreds of millions of people. Within the biotech world, pioneers like Alnylam and Intellia have demonstrated just how versatile LNPs can be as a delivery vehicle for anything from siRNA to CRISPR/Cas9.

No­vo CEO Lars Fruer­gaard Jør­gensen on R&D risk, the deal strat­e­gy and tar­gets for gen­der di­ver­si­ty

 

I kicked off our European R&D summit last week with a conversation involving Novo Nordisk CEO Lars Fruergaard Jørgensen. Novo is aiming to launch a new era of obesity management with a new approval for semaglutide. And Jørgensen had a lot to say about what comes next in R&D, how they manage risk and gender diversity targets at the trendsetting European pharma giant.

John Carroll: I’m here with Lars Jørgensen, the CEO of Novo Nordisk. Lars, it’s been a really interesting year so far with Novo Nordisk, right? You’ve projected a new era of growing sales. You’ve been able to expand on the GLP-1 franchise that was already well established in diabetes now going into obesity. And I think a tremendous number of people are really interested in how that’s working out. You have forecast a growing amount of sales. We don’t know specifically how that might play out. I know a lot of the analysts have different ideas, how those numbers might play out, but that we are in fact embarking on a new era for Novo Nordisk in terms of what the company’s capable of doing and what it’s able to do and what it wants to do. And I wanted to start off by asking you about obesity in particular. Semaglutide has been approved in the United States for obesity. It’s an area of R&D that’s been very troubled for decades. There have been weight loss drugs that have come along. They’ve attracted a lot of attention, but they haven’t actually ever gained traction in the market. My first question is what’s different this time about obesity? What is different about this drug and why do you expect it to work now whereas previous drugs haven’t?

UP­DAT­ED: FDA slaps As­traZeneca's MCL-1 can­cer drug with a hold af­ter safe­ty is­sue — 2 years af­ter Am­gen axed a trou­bled ri­val

There are new questions being posed about a class of cancer drugs in the wake of the second FDA-enforced clinical hold in the field.

Two years after the FDA hit Amgen with a clinical hold on its MCL-1 inhibitor AMG 397 following signs of cardiac toxicity, AstraZeneca says that regulators hit them with a hold on their rival therapy of the same class.

The pharma giant noted on clinicaltrials.gov that its Phase I/II study for the MCL-1 drug AZD5991 “has been put on hold to allow further evaluation of safety related information.”

Sur­geons suc­cess­ful­ly at­tach pig kid­ney to a hu­man for the first time, us­ing tech from Unit­ed's Re­vivi­cor

In a first, researchers reportedly successfully transplanted a pig kidney into a human without triggering an immediate immune response this week. And the technology came from the biotech United Therapeutics.

Surgeons spent three days attaching the kidney to the patient’s blood vessels, but when all was said and done, the kidney appeared to be functioning normally in early testing, Reuters and the New York Times were among those to report. The kidney came from a genetically altered pig developed through United’s Revivicor unit.

Sen­a­tors back FDA's plan to re­quire manda­to­ry pre­scriber ed­u­ca­tion for opi­oids

Three Senate Democrats are backing an FDA plan to require mandatory prescriber education for opioids as overdose deaths have risen sharply over the past decade, with almost 97,000 American opioid-related overdose deaths in the past year alone.

While acknowledging a decline in overall opioid analgesic dispensing in recent years, the FDA said it’s reconsidering the need for mandatory prescriber training through a REMS given the current situation with overdoses, and is seeking input on the aspects of the opioid crisis that mandatory training could potentially mitigate.

Bris­tol My­ers pledges to sell its Ac­celeron shares as ac­tivist in­vestors cir­cle Mer­ck­'s $11.5B buy­out — re­port

Just as Avoro Capital’s campaign to derail Merck’s proposed $11.5 billion buyout of Acceleron gains steam, Bristol Myers Squibb is leaning in with some hefty counterweight.

The pharma giant is planning to tender its Acceleron shares, Bloomberg reported, which add up to a sizable 11.5% stake. Based on the offer price, the sale would net Bristol Myers around $1.3 billion.

To complete its deal, Merck needs a majority of shareholders to agree to sell their shares.
