PDUFA Date Extended for Legend/Janssen Multiple Myeloma Drug

 The U.S. Food and Drug Administration (FDA) has extended Legend Biotech Corporation's Prescription Drug User Fee Act (PDUFA) target date for the drug it is developing to treat relapsed and/or refractory multiple myeloma. 

Legend Biotech's ciltacabtagene autoleucel (cilta-cel) is a BCMA-directed chimeric antigen receptor T cell (CAR-T) therapy that it is creating with partner Janssen Biotech. It is indicated for adults diagnosed with multiple myeloma. 

With the FDA's approval, the drug makers have until February 28, 2022 to review their findings and analytical processes. The PDUFA is a law that allows the FDA to collect fees from the drug makers as part of their application for approval. 

In February 2019, Cita-cel was granted Orphan Drug Designation, which progressed to a Breakthrough Therapy Designation by December of the same year. It was also at this time when its Biologics License Application was submitted. In May 2021, it was accepted under Priority Review. Legend Biotech and Janssen entered an exclusive collaboration deal to develop and commercialize the drug in 2017. 

"We are working closely with Janssen and the FDA to facilitate an efficient and thorough review of the BLA for cilta-cel. We remain confident that cilta-cel has shown great promise in patients with relapsed and refractory multiple myeloma, and we are focused on making this therapy available to them in the U.S. as soon as possible," said Ying Huang, Ph.D., chief executive officer and chief financial officer of Legend Biotech, in a statement. 

The BLA is based on results from the CARTITUDE-1 Phase IB/2 trial, which achieved the primary endpoint of safety and found the recommended Phase II dose in Phase IB and objective response rate (ORR) in Phase II. The original PDUFA target was November 29, 2021.

Janssen received word of the FDA's extension in October and then met with the FDA with Legend Biotech on November 1 to discuss the conditions of the change. It appears that the drug remains on schedule in February, as no additional clinical data have been requested. 

Multiple myeloma is an incurable type of blood cancer that begins in the bone marrow and is characterized by an overproduction of plasma cells. Current treatment interventions are able to place a patient in remission, but this is highly prone to relapse. 

Relapsed multiple myeloma is one that comes back after a year since an initial partial or total remission, while refractory multiple myeloma happens when a patient does not respond to treatment within 60 days from therapy. Prognosis is poor for those who have this disease.

Applications seeking the approval of cilta-cel are currently being reviewed by health authorities worldwide, including the U.S. FDA and the European Medicines Agency (EMA).

Novartis Links with UK's Dunad in $1.3 Billion Protein Degradation Deal

 Novartis has forged a collaboration with U.K.-startup Dunad Therapeutics to develop next-generation targeted protein-degradation therapies in a deal valued at up to $1.3 billion.

Dunad, which is based in Cambridge, England, emerged from stealth mode in March of this year, backed by the financial strength of Epidarex Capital. Dunad’s small molecule platform prompts the degradation of disease-causing proteins by modifying the target using mono-valent small molecules. Novartis is banking on Dunad’s claims that its novel approach is “fully tuneable to be exquisitely selective and underpinned by a target-class agnostic mechanism of action that is distinct from other targeted protein degradation technologies.” The small U.K. company believes its platform has the potential to develop orally bioavailable and CNS-accessible degrader therapeutics that can “significantly expand the frontiers of protein degradation targets.”

With Novartis, Dunad will apply its platform to generate novel covalent and targeted protein-degrading small molecule drugs focusing on up to four drug targets. Dunad will be responsible for the development of the assets until lead optimization. For its part, Novartis will contribute target and ligand knowledge. The Swiss pharma giant will also provide Dunad with access to unique assays and models and provide full funding for the project. Novartis will have an exclusive option to develop and commercialize any products that result from the agreement.

Under the terms of the deal, Novartis will provide Dunad with $24 million in an upfront payment and equity investment. Dunad will also be eligible for milestone payments that could climb to as much as $1.3 billion.

The protein degradation field has deepened with more companies investing resources into this approach. Companies like PhoreMost and Kymera Therapeutics have built a pipeline around the field. Earlier this year, Pfizer struck a $1 billion deal with Connecticut-based Arvinas to develop and commercialize its PROTAC estrogen receptor protein degrader. With the Dunad deal, Novartis will carve out its own stake with the intriguing modality.

Patrick Gunning, Ph.D., co-founder and acting chief executive officer and chief scientific officer of Dunad, expressed his excitement about the partnership with Novartis.

“This deal highlights the clear benefits our platform promises for the development of next-generation targeted protein degrader therapeutics. We are confident that with our approach of inducing degradation via direct modulation of target proteins with mono-valent small molecules, we can significantly expand the boundaries of targeted protein degraders as a therapeutic modality,” Gunning said in a statement.

Diana Kraskouskaya, Ph.D., co-founder and chief operating officer of Dunad, noted that the collaboration with Novartis is a significant milestone for the young company. She said the partnership will allow the company to “rapidly expand the impact of our platform technology to additional target classes and therapeutic areas, beyond Dunad’s own internal target pipeline.” Kraskouskaya added that Dunad is committed to advancing its pipeline to tackle previously intractable targets.

Moderna finally cracks into gene editing with Metagenomi pact

 We finally know who Moderna has been courting behind the scenes to make the big jump into gene editing. The famed biotech has signed a research partnership with CRISPR gene editing company Metagenomi.

Both parties are keeping mum on a lot of the details. We don’t know what indications they’ll go after, how many targets they will develop, how much Moderna will put up for research funding, how much was paid upfront, what the milestone or royalty payments will end up being down the line or how much of an equity investment Moderna made through the transaction.

We do know that the partnership will involve in vivo treatment options for serious genetic diseases. Metagenomi will offer up access to its gene editing tools while Moderna will bring the expertise in mRNA and lipid nanoparticle delivery technologies.

Moderna CEO Stephane Bancel made waves in August when he told investors during second-quarter earnings that the company planned to finally spend some of its billions in COVID-19 vaccine revenue on a gene editing deal of some kind. President Stephen Hoge further clarified that Moderna is interested in improving delivery mechanisms in gene editing with its mRNA technology.

So how did Metagenomi rise to the top in the field of available gene editing companies?

Turns out the small biotech had an in with Eric Huang, Ph.D., the general manager and chief scientific officer of Moderna Genomics; he serves on Metagenomi’s science advisory board.

“When they presented the data to me, I just found it irresistible,” Huang said. “And then once Moderna decided to invest in genomic medicine in general, I brought this opportunity to Stephane.”

He jokingly said there was “no bias” in the selection, that of course Moderna conducted thorough due diligence. He admits he’ll likely need to resign the SAB position now that the companies are tied up. Huang said the two companies have complementary cultures, and a desire to “dream big—too big, but do good science.”

Huang would not disclose financial details either but called the partnership “very significant” in terms of cash and research funding as well as the equity investment.

“We would love to be part of their success,” Huang said of Metagenomi. “We're gonna be tied at the hip for a while.”

Metagenomi’s discovery platform finds DNA from natural samples that can be sequenced to create new tools for gene editing. Drug candidates are then identified using AI. The small biotech is backed by Bayer, which signed on to an initial $65 million funding round at the end of 2020. That round was pushed up to $75 million in April with the addition of new investment from VC shop RA Capital.

Metagenomi CEO Brian Thomas called the Moderna partnership a natural one and said his company has benefited from Huang’s input over the past three years.

“As we started to grow closer in our discussions about the broad toolbox that Metagenomi is building, it became really clear that the two companies' missions were starting to align,” Thomas said.

This is Metagenomi's first partnership, too, although Thomas said others have been interested. But the biotech was waiting to find a partner that could bring a better delivery mechanism to the deal. 

Thomas and Huang were careful not to reveal the indications they’ll tackle, but they did say the underlying goal is to improve gene editing as a whole. As they work through the research partnership, they will select indications that seem promising along the way.

“We don't want to just do a simple gene knockout. We don't want to just do simple point mutation, single variant mutation,” Huang said. “We are dreaming bigger, creating different tools that scientists can think of that allow doctors to treat genetic diseases.”

The companies plan to deliver their medicine where other gene editing companies have already established a precedent—the liver, using delivery tech Moderna already has, Huang confirmed. He acknowledged that Intellia, the first company to present first-in-human data for a gene editing therapy this summer, is the “pioneer” in the space. That company’s technology targets the liver as well.

Moderna and Metagenomi will begin with building on technology that exists to get some candidates into the clinic as soon as possible, with a long-term goal of making broader improvements to gene editing.

“We have gene editing technology that's ready to go to the clinic right now. We plan to work with Moderna to move that into the clinic as fast as we can,” Thomas said. “But we also have a long-term vision to develop the best tools for in vivo gene editing, and that's going to be what we work on.”

Gene editing has so far focused on Cas9 technology, but Thomas thinks there’s more out there. The company recent unveiled data on its CRISPR-associated transposases system that can be used to precisely integrate large DNA fragments into genomes, allowing for new editing techniques beyond the currently available technology. 

“We're just at the tip of the iceberg … there's no reason why evolution would stop at Cas9 and only give us one thing,” he said.

Huang pointed to Moderna’s well documented history of a company that can take the long game or immediately pivot when, for example, the world needs a life-saving vaccine. The company developed its first vaccine in 2013, back when mRNA technology seemed as though it was “nothing valuable.” So a one- or two-year deal would not have been “satisfactory,” he said.

“I hope in five to 10 years’ time, when people are thinking about in vivo gene editing, they think of Moderna and Metagenomi together,” Huang said.

The question remains whether this will be Moderna's only partnership in gene editing, or if they will pile on others down the line. Huang was, as expected, tight lipped, but still open to the prospect for other deals. 

“We will be keeping our options open about complementary technologies that will be delivering or improving potencies in other aspects of genome editing, so Moderna will always keep an open mind and option."

Will Valneva , Dynavax Score With Late-to-the-Party COVID Vaccine?

 

  • Valneva's phase 3 data for its COVID-19 vaccine compared well against AstraZeneca's vaccine.
  • Dynavax is set to profit from sales of its adjuvant used in Valneva's vaccine.

Valneva (NASDAQ:VALN) recently reported positive results from a late-stage study of COVID-19 vaccine VLA2001. The vaccine uses Dynavax's (NASDAQ:DVAX) Cpg 1018 adjuvant. In this Motley Fool Live video recorded on Oct. 20, 2021, Motley Fool contributors Keith Speights and Brian Orelli discuss the potential for commercial success of this late-to-the-party vaccine.


Keith Speights: Let's switch to some other COVID-19 news from earlier this week. Valneva, ticker there is VALN, reported positive results from a Phase III study of its COVID-19 vaccine candidate, VLA2001. This vaccine uses the CpG 1018 adjuvant developed by Dynavax.

Brian, what do you make up of these results, and do you think Valneva and Dynavax could achieve significant commercial success with this vaccine, which is late to the party?

Brian Orelli: We talked about this vaccine, I think, a few weeks ago when the UK government pulled out of a supply agreement with Valneva. The Phase III data that was just released looked pretty good.

The study was comparing VLA2001 which is an inactivated virus to AstraZeneca's (NASDAQ:AZN) vaccine. VLA2001 produced higher antibody levels than AstraZeneca's vaccine, and the tolerability was better, at least in patients that were 30 years and older. Cases of COVID were similar between the two vaccines.

There were no severe disease in either group. That basically says that it's non-inferior on the ability to prevent COVID. Non-inferiority to an already approved drug is pretty standard for infectious diseases. If you have a new antibiotic, you can't compare it to placebo because you can not give patients antibiotic to deal with their infection. You've got to give them control, so you give them the current standard of care, and then you compare your drug to the current standard of care. If it works better, then that's great, and if it works the same well, the FDA's OK with approving it.

Are we at the point during the pandemic where regulators are OK with non-inferiority to a current standard of care? Maybe it seems reasonable to me, but I'm obviously not a regulator. We'll have to wait and see what the regulators think, but I think AstraZeneca should produce solid data, and so I think that comparing it to AstraZeneca's data seems reasonable to me.

The fact that it's producing better antibodies or higher levels of antibodies seems like a good thing and the fact that it's just as good for COVID cases seems reasonable. I think there's definitely a market, especially in the developing world. But as we've talked about previously, that's going to come with lower margins.

We'll have to wait and see how much Valneva can make off of this vaccine. In terms of Dynavax, Dynavax actually just sells the adjuvant to Valneva, so I think it'll make money no matter what the margins are that Valneva is making, although maybe if Valneva is not making as much, they try to squeeze Dynavax a little bit to try to get a lower price on the adjuvants and maybe that hurts Dynavax slightly.

Should Ocugen Be Soaring Yet?

 

  • A World Health Organization group meets on Wednesday to review Emergency Use Listing for Covaxin.
  • Ocugen's shares are likely to jump with this meeting due to investors' excitement and heavy short interest.
  • Ocugen has U.S. and Canadian rights to the COVID-19 vaccine, but EUL won't help in those markets.

Moderna's shares have more than tripled in value so far this year. BioNTech has been an even bigger winner for investors. Buying and holding the stocks of leading COVID-19 vaccine makers has turned out to be a pretty good strategy.

But there's one vaccine stock that has outperformed them all in 2021. Shares of Ocugen (NASDAQ:OCGN) have skyrocketed close to 550% year to date. Here's why the stock will probably soar even more tomorrow -- but shouldn't. 


Tomorrow -- Nov. 3, 2021 -- a World Health Organization (WHO) technical advisory group is scheduled to meet to review the data for COVID-19 vaccine Covaxin for a potential Emergency Use Listing (EUL). Bharat Biotech, the developer of Covaxin, first officially indicated its interest in receiving EUL for the vaccine back in April 2021. 

The technical advisory group has already met previously about Covaxin. However, the group requested some clarifications from Bharat. But the meeting on Wednesday of this week will be a final assessment of the vaccine's qualifications in receiving EUL.

There's no way to know for sure in advance what the technical advisory group's recommendation will be. The smart money, though, is on Covaxin winning EUL.

Covaxin has already won Emergency Use Authorization (EUA) in India, where Bharat is based. Obtaining EUL would clear the way for the vaccine to be distributed to nearly 200 countries that participate in the COVAX Facility, which aims to make COVID-19 vaccines available across the world. 


Ocugen shares skyrocketed more than 20% on the day of the first WHO technical advisory group meeting. There's no reason to doubt that history will repeat itself this week. However, there's also no good reason for the stock to jump.

The fact of the matter is that EUL for Covaxin doesn't immediately benefit Ocugen. Sure, the company has marketing rights to the vaccine in the U.S. and Canada. Neither of those countries will receive vaccines as part of the COVAX Facility, though. They're both donors to the initiative.

So why might Ocugen's shares soar tomorrow anyway? It's important to understand the intense interest in the stock among online investing communities. At the same time, the stock has attracted plenty of short-sellers. As of Oct. 15, 2021, close to 29.5% of Ocugen's stock float was sold short

Because of these two factors, any perceived good news for Ocugen is likely to light a fire beneath its stock. That can happen even when the good news doesn't directly help the company, as is the case with potential EUL for Covaxin.


What really matters the most for Ocugen right now is winning authorization for Covaxin in Canada. The company has completed its submission to Health Canada and awaits a decision.

The second most important thing that matters for Ocugen is moving forward with a pivotal phase 3 study of Covaxin in the U.S. Ocugen announced last week that it has filed an Investigational New Drug (IND) application with the U.S. Food and Drug Administration (FDA) to begin this study. 

However, the FDA must first give a green light for the phase 3 study. Ocugen plans to only enroll several hundred participants who have either not been vaccinated or who have received two doses of a messenger RNA vaccine at least six months earlier.

This study would be far smaller than the pivotal studies of other COVID-19 vaccines that have been authorized or approved in the U.S. Ocugen hopes that the FDA will agree that the relatively small study will be sufficient to demonstrate similarity with results obtained in a larger study conducted in India with 25,798 participants.

If the FDA allows Ocugen's study to move forward, it would provide a good reason for investors to get excited. The company thinks that it could wrap up the study in the first half of 2022. That could set the stage for Ocugen to file for full FDA approval of Covaxin shortly afterward.

China won’t give up on its zero-tolerance COVID policy soon

 China will not give up on its zero-tolerance policy towards local COVID-19 cases any time soon, some experts said, as the policy has allowed it to quickly quell local outbreaks, while the virus continues to spread outside its borders.

To stop local cases from turning into wider outbreaks, China has developed and continually refined its COVID-fighting arsenal — including mass testing, targeted lockdowns and travel restrictions – even when those anti-COVID measures occasionally disrupted local economies.

“The policy (in China) will remain for a long time,” Zhong Nanshan, a respiratory disease expert who helped formulate China’s COVID strategy in early 2020, told state media.

“How long it will last depends on the virus-control situation worldwide.”

In a major outbreak in July-August, China counted a total of over 1,200 local symptomatic infections. In the latest flare-up, mostly in northern China, some 538 local cases were reported between Oct. 17 and Nov. 1.

Despite the lower caseload, the geographical spread of the infections has put constraints on China’s leisure and tourism sectors.

Since Oct. 23, travel agencies have not been allowed to organise tourism between certain provinces, with such restrictions affecting trips to nearly one-third of the mainland’s 31 province-level regions including Beijing.

Many cities with infections have also closed indoor entertainment and cultural venues. A flurry of marathons, theatrical performances and concerts have been delayed or cancelled.

China also requires weeks of quarantine for most travellers arriving from abroad.

In contrast, some Asia-Pacific countries are starting to open selectively to fully vaccinated international travellers as they seek to secure a more normal footing for their economies and societies.

ANOTHER YEAR?

The successful containment of clusters and popular support for restricting international travel make it overwhelmingly likely that China will stick to its zero tolerance towards domestic cases for at least another year, Gavekal Dragonomics analyst Ernan Cui said in a note.

“Officials seem to believe that giving up on the zero-tolerance approach would just replace one set of problems with another,” wrote Cui.

Respiratory disease expert Zhong told state media CGTN that the current 2% death rate of the disease globally, despite vaccination, is not tolerable in China.

“Zero tolerance costs a lot indeed, but letting the virus spread costs more,” Zhong said.

Some countries had loosened curbs while still reporting some small clusters, leading to a new series of infections that have since forced them to backpedal again, Zhong said.

Such back-and-forth in policy costs more, and has a greater impact on the public, he warned.

The cost of treating COVID patients – on average 20,000 yuan each and sometimes over 1 million yuan for those critically ill – totalled 2.8 billion yuan ($438 million) as of end-June, all paid by the government, state television said in August.
