Sun Phar­ma takes aim at a crowd­ed mar­ket with an­oth­er IL-23 pso­ri­a­sis drug from Mer­ck

Jes­per Jensen, Sun Phar­ma­ceu­ti­cals

In the last minute, late-stage race to the mar­ket with a new round of pso­ri­a­sis drugs, In­dia’s Sun Phar­ma­ceu­ti­cals is mak­ing its own bid with a new drug called tildrak­izum­ab. In-li­censed from Mer­ck, which agreed to han­dle the late-stage work for Sun for the for­mer MK-3222, it’s an­oth­er IL-23 drug, like J&J’s guselkum­ab.

But it didn’t per­form as well as the J&J drug in late-stage de­vel­op­ment.

Over the week­end, Sun tout­ed a late break­er at EADV which demon­strat­ed that their drug hit the pri­ma­ry end­point in the study, adding im­proved 28-week scores that demon­strat­ed it was ef­fec­tive in a ma­jor­i­ty of pa­tients.

The trou­ble, though, is that their drug was clear­ly over­shad­owed by guselkum­ab, an­oth­er IL-23 drug that’s now an­gling to hit the mar­ket to com­pete against two oth­er re­cent ar­rivals: No­var­tis’s Cosen­tyx and Eli Lil­ly’s Taltz (ix­ek­izum­ab). Both of those drugs are IL-17 ther­a­pies, a group which Valeant may well soon join af­ter its ap­pli­ca­tion for bro­dalum­ab — in-li­censed from As­traZeneca — goes through.

First, the da­ta.

An av­er­age of 64% and 78% of pa­tients re­ceiv­ing two in­jec­tions of a 200 mg dose achieved PASI 75 score af­ter 12 and 28 weeks. The da­ta fur­ther showed that a high­er num­ber of pa­tients on tildrak­izum­ab achieved PASI 90 and 100 com­pared to place­bo and En­brel (etan­er­cept). For tildrak­izum­ab, 54% and 59% of pa­tients (at 100 mg and 200 mg) achieved PASI 90 at week 28, sig­nif­i­cant­ly bet­ter than En­brel’s 31%.

But there­in lies the rub.

At week 16, the guselkum­ab pa­tients achieved a 73.3% PASI 90 rate. At week 24, the pro­por­tion of pa­tients who achieved a PASI 90 re­sponse was sig­nif­i­cant­ly high­er in the guselkum­ab group com­pared with the Hu­mi­ra group (80.2% vs. 53%, re­spec­tive­ly).

Guselkum­ab not on­ly hand­i­ly beat out Sun’s drug, the Sun ther­a­py al­so scored un­com­fort­ably close to the old main­stay Hu­mi­ra, which is — some­time in the next few years — go­ing to go gener­ic.

“I think it’s very hard to com­pare be­tween stud­ies,” says Jes­per Jensen, Sun’s ex­ec­u­tive vice pres­i­dent for bi­o­log­ics and der­ma­tol­ogy, who be­lieves that tildrak­izum­ab is well set up for its com­ing re­view by the FDA and like­ly ar­rival on the mar­ket.

Both drugs have helped demon­strate that IL-23 is a good tar­get for pso­ri­a­sis, he adds. In ad­di­tion: “We’re still see­ing many pa­tients not get­ting to goal.”

The two drugs were al­so dosed dif­fer­ent­ly, says Jensen, which could al­so ex­plain the dif­fer­ence in the out­comes.

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 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.
