Chi­nese vac­cine de­vel­op­ers have be­gun to shed some se­cre­cy around Covid-19 can­di­dates. What do we know?

Last November, Nisa Leung found herself catching up with Margaret Chan in a conference at Beijing, wondering when the next pandemic may be.

Leung, now a managing partner at Qiming, had just graduated from business school at Stanford when she was asked to introduce infectious disease experts to Chan, then Hong Kong’s Secretary of Health. The year was 2003; the city was grappling with a local outbreak of a deadly coronavirus disease — later named the severe acute respiratory syndrome, or SARS — that began with a patient zero from mainland China.

“I still remember very clearly that back then we tried to develop a diagnostic test in China and we kind of just didn’t have the capability,” Leung said. “And so we had to send the strains to the US for a company to develop it for us.”

'Ex­treme­ly po­lit­i­cal' — Trump neuters FDA's at­tempt to strength­en vac­cine EUA, ques­tions need to length­en process

Stephen Hahn went before a Senate committee Wednesday and declared he’s fighting. “Every one of the decisions we have reached has been made by career FDA scientists based on science and data, not politics,” he exclaimed, adding that “FDA will not permit any pressure from anyone to change that. I will fight for science.”

A few hours later, he was undermined by President Donald Trump when a reporter asked if he was okay with stricter vaccine guidelines that the FDA was said to be cooking up. “That has to be approved by the White House. We may or may not approve it. That sounds like a political move,” he decided.

Azar falls in line un­der Trump again. Ex­perts say he's re­in­forc­ing a dark sig­nal sent to the FDA

In the latest incident where Alex Azar has steadfastly taken the side of President Donald Trump over that of the FDA, the HHS secretary was noncommittal this morning when asked if he supports the attempt by his subordinates at the FDA to strengthen guidelines for a vaccine EUA.

Appearing on NBC’s Today Show, the HHS secretary deliberately muddied the waters, stating that the guidance that matters is the one that is “actually already out there.”

Covid-19 roundup: Op­er­a­tion Warp Speed's 7th vac­cine is live at­ten­u­at­ed; Small biotech touts big suc­cess where gi­ants have failed

Operation Warp Speed is stacking its vaccine portfolio with a “TBD” new candidate: a live attenuated vaccine that can be administered in a single dose, potentially as an oral formulation rather than an injection.

Sound familiar?

That could be because the unannounced candidate appears to match the profile of an inoculation being developed by Merck, according to Bloomberg, which first reported the development based on a presentation by Moncef Slaoui.

Fol­low­ing a hefty Se­ries B, Sil­ver­back Ther­a­peu­tics quick­ly pulls in $85 mil­lion for 'an im­por­tant growth phase'

Months after reeling in a $78 million Series B round, Silverback Therapeutics has hooked an even larger Series C.

The Seattle-based company announced Wednesday that it netted $85 million from a slate of new and previous investors. The quick boost could be a sign that an IPO is on the way.

In an email, Silverback CEO Laura Shawver told me she was “not able to provide any additional comments about Silverback” beyond what was shared in the company’s news release. In the prepared statement, she said the company is at “an important growth phase.”

UP­DAT­ED: Still held down by clin­i­cal hold, No­var­tis' Zol­gens­ma falls fur­ther be­hind Bio­gen and Roche as FDA asks for a new piv­otal study

Last October, the FDA slowed down Novartis’ quest to extend its gene therapy to older spinal muscular atrophy patients by slapping a partial hold on intrathecal administration. Almost a year later, the hold is still there, and regulators are adding another hurdle required for regulatory submission: a new pivotal confirmatory study.

The new requirement — which departs significantly from Novartis’ prior expectations — will likely stretch the path to registration beyond 2021, when analysts were expecting a BLA submission. That could mean more time for Biogen to reap Spinraza revenues and Roche to ramp up sales of Evrysdi in the absence of a rival.

Gilead agreed to pay $97 million to settle allegations that it illegally used a charity to pay thousands of Medicare patients’ co-payments for its pulmonary arterial hypertension drug Letairis.

The US government claimed that between June 2007 and December 2010, Gilead $GILD used the Caring Voice Coalition as a conduit to cover the costs of just its own drug. The alleged behavior goes against the False Claims Act.

On­ly five months af­ter a Se­ries A launch, Taysha goes pub­lic with $157M IPO

As has been the trend in 2020, Taysha Gene Therapies has become the latest biotech to make a quick ascent from a small, privately-funded company to enjoying its very own Nasdaq ticker.

The Dallas-based biotech raised $157 million for its IPO after pricing shares at $20 apiece Thursday, the high-point of its expected range. Initially pegging $100 million in financing, Taysha offered a little less than 8 million shares and will trade under the $TSHA symbol.

Chair of FDA's vac­cine ad­comm — who's al­so a lead in­ves­ti­ga­tor of Mod­er­na's vac­cine — re­cus­es her­self from Covid-19 talks

When the FDA’s Vaccines and Related Biological Products Advisory Committee meets next month to discuss the development and authorization of Covid-19 vaccines, the chairwoman won’t be there.

Hana El Sahly has recused herself from the expert panel’s review of the topic, citing her role as a lead investigator in Moderna’s Phase III trial, Reuters reported. An associate professor of virology and microbiology at Baylor College of Medicine in Houston, El Sahly was appointed the chairwoman last year.
