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.”

With ad­u­canum­ab caught on a cliff, Bio­gen’s Michel Vounatsos bets bil­lions on an­oth­er high-risk neu­ro play

With its FDA pitch on the Alzheimer’s drug aducanumab hanging perilously close to disaster, Biogen is rolling the dice on a $3.1 billion deal that brings in commercial rights to one of the other spotlight neuro drugs in late-stage development — after it already failed its first Phase III.

The big biotech has turned to Sage Therapeutics for its latest deal, close to a year after the crushing failure of Sage-217, now dubbed zuranolone, in the MOUNTAIN study.

As­traZeneca, Ox­ford on the de­fen­sive as skep­tics dis­miss 70% av­er­age ef­fi­ca­cy for Covid-19 vac­cine

On the third straight Monday that the world wakes up to positive vaccine news, AstraZeneca and Oxford are declaring a new Phase III milestone in the fight against the pandemic. Not everyone is convinced they will play a big part, though.

With an average efficacy of 70%, the headline number struck analysts as less impressive than the 95% and 94.5% protection that Pfizer/BioNTech and Moderna have boasted in the past two weeks, respectively. But the British partners say they have several other bright spots going for their candidate. One of the two dosing regimens tested in Phase III showed a better profile, bringing efficacy up to 90%; the adenovirus vector-based vaccine requires minimal refrigeration, which may mean easier distribution; and AstraZeneca has pledged to sell it at a fraction of the price that the other two vaccine developers are charging.

Af­ter Ko­dak de­ba­cle, US lends $1.1B to a syn­thet­ic bi­ol­o­gy com­pa­ny and their big Covid-19, mR­NA plans

In mid-August, as Kodak’s $765 million government-backed push into drug manufacturing slowly fell apart in national headlines, Ginkgo Bioworks CEO Jason Kelly got a message from his company’s government liaison: HHS wanted to know if they, too, might want a loan.

The government’s decision to lend Kodak three quarters of a billion dollars raised eyebrows because Kodak had never made drugs before. But Ginkgo, while not a manufacturing company, had spent the last decade refining new ways to produce materials inside cells and building automated facilities across Boston.

FDA hands Liq­uidia and Re­vance a CRL and de­fer­ral, re­spec­tive­ly, as Covid-19 cre­ates in­spec­tion chal­lenge

Two biotechs said they got turned away by the FDA on Wednesday, in part due to pandemic-related travel restrictions.

North Carolina-based Liquidia Technologies was handed a CRL for its lead pulmonary arterial hypertension drug, citing the need for more CMC data and on-site pre-approval inspections, which the FDA hasn’t been able to conduct due to travel restrictions. The agency also deferred its decision on Revance Therapeutics’ BLA for its frown line treatment, because it needs to inspect the company’s northern California manufacturing facility. The action, Revance emphasized, was not a CRL.

Chi­na opens the door for biotech in­vestors in Hong Kong to buy Shang­hai stocks, and vice ver­sa

When Shanghai’s STAR board began opening its doors to biotech, it was considered not just a rival to Nasdaq but also the stock exchange in Hong Kong. Those perceptions may take an amicable turn as China expands a mutual access program with the city.

The changes mean investors in mainland China will be able to own Hong Kong biotech chapter stocks, while those in Hong Kong — a much more internationally connected group — would have access to those listed on STAR. In effect, it turns the Shanghai market into a globally accessible exchange overnight while also broadening a key source of revenue for HKEX.

In fi­nal days at Mer­ck, Roger Perl­mut­ter bets big on a lit­tle-known Covid-19 treat­ment

Roger Perlmutter is spending his last days at Merck, well, spending.

Two weeks after snapping up the antibody-drug conjugate biotech VelosBio for $2.75 billion, Merck announced today that it had purchased OncoImmune and its experimental Covid-19 drug for $425 million. The drug, known as CD24Fc, appeared to reduce the risk of respiratory failure or death in severe Covid-19 patients by 50% in a 203-person Phase III trial, OncoImmune said in September.

Trail­ing Eli Lil­ly by 12 days, Re­gen­eron gets the FDA OK for their Covid-19 an­ti­body cock­tail

A month and a half after becoming the experimental treatment of choice for a newly diagnosed president, Regeneron’s antibody cocktail has received emergency use authorization from the FDA. It will be used to treat non-hospitalized Covid-19 patients who are at high-risk of progressing.

Although the Rgeneron drug is not the first antibody treatment authorized by the FDA, the news comes as a significant milestone for a company and a treatment scientists have watched closely since the outbreak began.

Covid-19 roundup: Eu­rope pur­chas­es 80M dos­es of Mod­er­na's vac­cine; CO­V­AXX se­cures $2.8B in emerg­ing mar­ket pre-or­ders

With the announcement of its vaccine efficacy data last week, Moderna is starting to line up customers for its Covid-19 mRNA jabs.

The Massachusetts-based biotech announced Wednesday it has agreed to sell an initial round of 80 million doses to the European Commission, with the option to double the amount to 160 million. Once the member states rubber stamp the approval, the deal will be finalized.

The ad­u­canum­ab co­nun­drum: The PhI­II failed a clear reg­u­la­to­ry stan­dard, but no one is cer­tain what that means any­more at the FDA

Eighteen days ago, virtually all of the outside experts on an FDA adcomm got together to mug the agency’s Billy Dunn and the Biogen team when they presented their upbeat assessment on aducanumab. But here we are, more than 2 weeks later, and the ongoing debate over that Alzheimer’s drug’s fate continues unabated.

Instead of simply ruling out any chance of an approval, the logical conclusion based on what we heard during that session, a series of questionable approvals that preceded the controversy over the agency’s recent EUA decisions has come back to haunt the FDA, where the power of precedent is leaving an opening some experts believe can still be exploited by the big biotech.
