CHMP rec­om­mends OK for Al­ny­lam's patisir­an; Am­gen scraps a BC­MA ADC

→ Al­ny­lam $AL­NY took an­oth­er big step to­ward get­ting a Eu­ro­pean ap­proval for patisir­an. The biotech says that the CHMP rec­om­mend­ed an OK for hered­i­tary transthyretin-me­di­at­ed amy­loi­do­sis (hAT­TR amy­loi­do­sis) in adult pa­tients with stage 1 or stage 2 polyneu­ropa­thy. A for­mal OK is like­ly. The drug is fac­ing an Au­gust 11 PDU­FA date at the FDA.

→ Por­to­la $PT­LA, though, isn’t mak­ing any head­way with be­trix­a­ban. The CHMP bat­ted back the com­pa­ny’s ap­peal of its ear­li­er re­jec­tion. Here’s a sum­ma­ry of all the ac­tion at the EMA to­day.

→ Am­gen is scrap­ping one of its an­ti­body-drug con­ju­gates as it shifts fo­cus to a BiTE pro­gram it has in de­vel­op­ment. In the Q2 call out­go­ing R&D chief Sean Harp­er not­ed that “by the end of this year, we ex­pect ini­tial Phase 1 da­ta from our BC­MA BiTE, AMG 420, in mul­ti­ple myelo­ma and our CD33 BiTE, AMG 330, in AML. We look for­ward to ad­di­tion­al da­ta from oth­er BiTE pro­grams over the next year or two, in­clud­ing both liq­uid and sol­id tu­mors. We’ve al­so de­pri­or­i­tized AMG 224, our BC­MA an­ti­body-drug con­ju­gate, based on ear­ly da­ta reads from our AMG 224 and AMG 420 pro­grams that sup­port our view that our BiTE tech­nol­o­gy may be su­pe­ri­or to cur­rent ADC tech­nolo­gies.”

→ Tiny Char­lottesville, VA-based Adi­al Phar­ma­ceu­ti­cals joined the IPO crowd to­day, pric­ing shares at $5 and rais­ing a lit­tle more than $7 mil­lion. The mon­ey will be used to ad­vance a drug to treat al­co­hol abuse.

Un­der fire, FDA to is­sue stricter guid­ance for Covid-19 vac­cine EUA this week — re­port

The FDA has been insisting for months that a Covid-19 vaccine had to be at least 50% effective – a measure of transparency meant to shore public trust in the agency and in a vaccine that had been brought forward at record speed and record political pressure. But now, with concerns of a Trump-driven authorization arriving before the election, the agency may be raising the bar.

The FDA is set to release new guidance that would raise safety and efficacy requirements for a vaccine EUA above earlier guidance and above the criteria used for convalescent plasma or hydroxychloroquine, The Washington Post reported. Experts say this significantly lowers the odds of an approval before the election on November 3, which Trump has promised despite vocal concerns from public health officials.

Trump’s HHS claims ab­solute au­thor­i­ty over the FDA, clear­ing path to a vac­cine EUA

The top career staff at the FDA has vowed not to let politics overrule science when looking at vaccine data this fall. But Alex Azar, who happens to be their boss’s boss, apparently won’t even give them a chance to stand in the way.

In a new memorandum issued Tuesday last week, the HHS chief stripped the FDA and other health agencies under his purview of their rule making ability, asserting all such power “is reserved to the Secretary.” Sheila Kaplan of the New York Times first obtained and reported the details of the September 15 bulletin.

News brief­ing: Tiny Vac­cinex's drug flops in PhII Hunt­ing­ton's tri­al, stock craters; Siol­ta nabs $30M Se­ries B to de­vel­op mi­cro­bio­me drug

Siolta Therapeutics, a microbiome company targeting allergic diseases, raked in a $30 million Series B to develop its lead candidate, STMC-103H. The drug, which has been FDA fast-tracked, is headed for proof-of-concept trials, according to the company. Its various indications include allergic asthma, food allergies, atopic dermatitis, allergic rhinitis, and allergy prevention.

The news comes just after the California-based biotech added a prominent biopharma veteran as an advisor: 20-year Gilead CEO John Martin. The biotech also gained Richard Shames as CMO, who came by way of Protagonist Therapeutics.

Af­ter bruis­ing re­jec­tion, blue­bird and Bris­tol My­ers Squibb land ide-cel pri­or­i­ty re­view. But will it mat­ter for the CVR?

With the clock all but up, the FDA accepted and handed priority review to Bristol Myers Squibb and bluebird bio’s BCMA CAR-T, keeping a narrow window open for Celgene investors to still cash in on the $9 CVR from the $63 billion Celgene merger.

The acceptance comes five months after the two companies weres slammed with a surprise refuse-to-file that threatened to foreclose the CVR entirely. Today’s acceptance sets the FDA decision date for March 27, 2021 – or precisely 4 days before the CVR deadline of March 31. Given the breakthrough designation and strong pivotal data — 81.5% response rate, 35.2% complete response rate — priority review was largely expected.

Blue­print plots re­turn to FDA with new Ay­vak­it da­ta in rare con­di­tion — and the an­a­lysts cheer

Over a decade after launch, Blueprint Medicines nabbed the first approval for their first drug earlier this year. Now, as they move forward with a Roche-partnered global launch, they’re touting data that could push them into more patients.

The Jeff Albers-led Cambridge biotech released their full pivotal data for Ayvakit in patients with advanced systemic mastocytosis. In one 53-person study, they showed that 76% of patients responded to the drug, 36% had complete responses and that on average their responses lasted for just over 3 years. A smaller, 32-patient study had a 75% response rate and most were still responding after 10.4 months, the last follow-up.

Signs of an 'Oc­to­ber Vac­cine Sur­prise' alarm ca­reer sci­en­tists. HHS con­tin­ues to claim Azar “will de­fer com­plete­ly to the FDA"

President Donald Trump, who seems intent on announcing a Covid-19 vaccine before Election Day, could legally authorize a vaccine over the objections of experts, officials at the FDA and even vaccine manufacturers, who have pledged not to release any vaccine unless it’s proved safe and effective.

In podcasts, public forums, social media and medical journals, a growing number of prominent health leaders say they fear that Trump — who has repeatedly signaled his desire for the swift approval of a vaccine and his displeasure with perceived delays at the FDA — will take matters into his own hands, running roughshod over the usual regulatory process.

#ES­MO20: Push­ing in­to front­line, Mer­ck and Bris­tol My­ers duke it out with new slate of GI can­cer da­ta

Having worked in parallel for years to move their respective PD-1 inhibitors up to the first-line treatment of gastrointestinal cancers, Merck and Bristol Myers Squibb finally have the data at ESMO for a showdown.

Comparing KEYNOTE-590 and CheckMate-649, of course, comes with the usual caveats. But a side-by-side look at the overall survival numbers also offer some perspective on a new frontier for the reigning checkpoint rivals, both of whom are claiming to have achieved a first.

News brief­ing: Bausch Health clos­ing in on deal to ac­quire Al­le­gro as­sets; PharmAbcine strikes deal with Sam­sung Bi­o­log­ics to de­vel­op an­ti­body pro­gram

Bausch Health is closing in on a deal that would allow it to buy out all of Allegro Ophthalmics’ eye-related assets — including the rights to lead candidate risuteganib — for $50 million.

The payment would be made in two tranches: $10 million at signing, and $40 million in 2021.

Risuteganib is in clinical development for intermediate dry Age-related Macular Degeneration (AMD). It’s expected to enter two concurrent Phase III trials for that indication in the next year. The drug is also being tested in patients with diabetic macular edema (DME), and last year met the primary endpoint in a Phase II study, with 48% of patients gaining 8 or more letters in visual acuity from baseline at week 28, compared to 7% in the control group at week 12.

UP­DAT­ED: Two wild weeks for Grail end in $8B Il­lu­mi­na buy­out

Grail’s whirlwind two weeks have ended in the wealthy arms of its former founder and benefactors.

Illumina has shelled out $8 billion to reacquire the closely-watched liquid biopsy startup they spun out just 5 years ago and sold off much of its shares just 3 years ago. The deal comes nearly two weeks after the well-heeled startup filed for a potentially massive IPO — one that was disrupted just a week later when Bloomberg reported that Illumina was in talks to buy their former spinout for up to $8 billion.
