Positive results from CIRM-funded LAD-I trial presented at the 62nd American Society of Hematology Annual Meeting

by Yimy Villa

Gaurav Shah, M.D., CEO and President of Rocket Pharmaceuticals

Leukocyte Adhesion Deficiency-I (LAD-I) is a rare pediatric disease caused by a mutation in a specific gene that causes low levels of a protein called CD18. Due to low levels of CD18, the adhesion of immune cells is affected, which negatively impacts the body’s ability to combat infections.

Rocket Pharmaceuticals is conducting a CIRM-funded ($6.56 M) clinical trial that is testing a treatment that uses a gene therapy called RP-L201. The therapy uses a patient’s own blood stem cells and inserts a functional version of the gene.  These modified stem cells are then reintroduced back into the patient. The goal is to establish functional immune cells, enabling the body to combat infections. Previous studies have indicated that an increase in CD18 to 4-10% is associated with survival into adulthood.

The company presented interim data from the trial at the 62nd American Society of Hematology (ASH) Annual Meeting in the form of an oral presentation. The data presented is from three pediatric patients with severe LAD-I, which is defined by CD18 expression of less than 2%. The patients were all treated with RP-L201. Patient One was 9-years of age at enrollment and had been followed for 12-months as of a cutoff date of November 2020. Patient Two was 3-years of age at enrollment and had been followed for over 6-months. Patient Three was 7-months of age at enrollment and was recently treated with RP-L201.

Key highlights from the presentation include:

  • RP-L201 was well tolerated, no safety issues reported with infusion or post-treatment
  • All patients achieved hematopoietic (blood) reconstitution within 5-weeks
    • 12 months post-treatment, Patient One demonstrated durable CD18 expression of approximately 40%,
    • 6-months post-treatment, Patient Two demonstrated CD18 expression of 23%
    • 2-months post-treatment, Patient Three demonstrated CD18 expression of 76%

In a press release from Rocket, Gaurav Shah, M.D., CEO and President of Rocket, expressed excitement about these results.

“…we continue to see encouraging evidence of efficacy for RP-L201 for the treatment of LAD-I. Patients have shown sustained CD18 expression of 23% to 40%, far exceeding the 4-10% threshold associated with survival into adulthood…”

Let Me Introduce You To “The Stem Cellar”

New post on The Stem Cellar

You can’t take it if you don’t make it

by Kevin McCormack

Following the race to develop a vaccine for COVID-19 has been a crash course in learning how complicated creating a new therapy is. It’s not just the science involved, but the logistics. Coming up with a vaccine that is both safe and effective is difficult enough, but then how do you make enough doses of it to treat hundreds of millions of people around the world?

That’s a familiar problem for stem cell researchers. As they develop their products they are often able to make enough cells in their own labs. But as they move into clinical trials where they are testing those cells in more and more people, they need to find a new way to make more cells. And, of course, they need to plan ahead, hoping the therapy is approved by the Food and Drug Administration, so they will need to be able to manufacture enough doses to meet the increased demand.

We saw proof of that planning ahead this week with the news that Cedars-Sinai Medical Center in Los Angeles has opened up a new Biomanufacturing Center.

Dr. Clive Svendsen, executive director of the Cedars-Sinai Board of Governors Regenerative Medicine Institute, said in a news release, the Center will manufacture the next generation of drugs and regenerative medicine therapies.

“The Cedars-Sinai Biomanufacturing Center leverages our world-class stem-cell expertise, which already serves scores of clients, to provide a much-needed biomanufacturing facility in Southern California. It is revolutionary by virtue of elevating regenerative medicine and its therapeutic possibilities to an entirely new level-repairing the human body.”

This is no ordinary manufacturing plant. The Center features nine “clean rooms” that are kept free from dust and other contaminants. Everyone working there has to wear protective suits and masks to ensure they don’t bring anything into the clean rooms.

The Center will specialize in manufacturing induced pluripotent stem cells, or iPSCs. Dhruv Sareen, PhD, executive director of the Biolmanufacturing Center, says iPSCs are cells that can be turned into any other kind of cell in the body.

“IPSCs are powerful tools for understanding human disease and developing therapies. These cells enable us to truly practice precision medicine by developing drug treatments tailored to the individual patient or groups of patients with similar genetic profiles.”

The Biomanufacturing Center is designed to address a critical bottleneck in bringing cell- and gene-based therapies to the clinic. After all, developing a therapy is great, but it’s only half the job. Making enough of it to help the people who need it is the other half.

CIRM is funding Dr. Svendsen’s work in developing therapies for ALS and other diseases and disorders.

Immune System Disorders From “Stem Cellar”

Biotechnology companies join forces in developing treatment for X-SCID

by Yimy Villa

Jasper Therapeutics, Inc., a biotechnology company focused on blood stem cell therapies, and Graphite Bio, Inc., a biotechnology company focused on gene editing therapies to treat or cure serious diseases, announced a research and clinical collaboration for a treatment for X-SCID.

X-SCID, which stands for X-linked severe combined immunodeficiency, is a genetic disorder that interferes with the normal development of the immune system, leaving infants vulnerable to infections that most people can easily fight off. One treatment for X-SCID involves a blood stem cell transplant, in which the patient’s defective stem cells are wiped out with chemotherapy or radiation to make room for normal blood stem cells to take their place. Unfortunately, the problem with chemotherapy or radiation in young infants is that it can lead to lifelong effects such as neurological impairment, growth delays, infertility, and risk of cancer.

Fortunately, Jasper Therapeutics has developed JSP191, a non-toxic alternative to chemotherapy and radiation. It is an antibody that works by targeting and removing the defective blood forming stem cells. The approach has previously been used in a CIRM-funded clinical trial ($20M award) for X-SCID.

Graphite Bio has developed GPH201, the first-in-human investigational blood stem cell treatment that will be evaluated as a potential cure for patients suffering from X-SCID. GPH201 is generated using precise and efficient gene editing technology, It works by directly replacing a defective gene that causes problems with the immune system. The hope is that GPH201 will ultimately lead to the production of fully functional, healthy immune cells.

The ultimate goal of this collaboration is to use JSP191 as the non-toxic alternative to chemotherapy in patients in order to remove their defective blood stem cells. After that, the gene editing blood stem cell technology developed by Graphite Bio can be introduced to patients in order to treat X-SCID. The two companies have agreed to collaborate on research, and potentially a clinical study, evaluating JSP191 as the non-toxic conditioning agent for GPH201.

In a press release, Josh Lehrer, M.Phil., M.D., chief executive officer at Graphite Bio, expressed excitement about the collaboration between the two companies.

“This collaboration with Jasper demonstrates our shared commitment to pioneering novel therapeutic approaches with the potential to significantly improve the treatment experiences of individuals with devastating conditions who stand to benefit from gene replacement therapies, initially for patients with XSCID. GPH201 harnesses our targeted gene integration platform to precisely target the defective gene that causes XSCID and replace it with a normal copy.”

In the same press release, Bill Lis, executive chairman and CEO of Jasper Therapeutics, also expressed optimism in regards to the two companies teaming up.

“Our collaboration with Graphite Bio is an exciting opportunity to further advance the field of curative gene correction by combining a targeted gene integration platform with our first-in-class targeted CD117 antibody, JSP191, that has already demonstrated preliminary clinical efficacy and safety as a conditioning agent in X-SCID patients and those with blood cancers undergoing allogeneic hematopoietic stem cell transplant.”

Graphite Bio is also developing gene editing technology to help treat sickle cell disease.  It is currently supported by a CIRM  late stage preclinical grant ($4.8M award). Th goal is to complete the final preclinical studies, which will allow Graphite Bio to start clinical studies of the sickle cell disease gene therapy in sickle cell patients in 2021.

Diabetes Research NEWS from Boston, Massachusetts

“November 10, 2020
“Dear Friends,

“As a year like no other ends, we begin to look forward to 2021 and the possibilities ahead.  At the start of 2020, we were focused on the Phase II clinical trial using the BCG vaccine in adults with established type 1 diabetes.  We were also planning for the Expanded Access program and a long anticipated pediatric clinical trial.  All of these steps are underway and our commitments to type 1 diabetes will never waiver, but COVID-19 has created a new challenge and amazing opportunities for the type 1 diabetic community.

“In 2013, we started a working group of BCG researchers around the globe to collaborate and share information on the BCG vaccine and its potential to treat diseases beyond its original purpose of preventing tuberculosis.  At the time, we were excited about autoimmunity and allergies, but were also interested in how BCG interacts with the immune system and benefits diverse immune responses.  As the COVID-19 epidemic spread and past and recent studies began to show a clear trend that BCG-vaccinated populations had protection from infections including perhaps lower rates of mortality for COVID-19, members of our working group sprang into action.  MGH is now one of several BCG working group members conducting COVID-19 prevention trials around the globe.  Here at MGH, we are also investigating if the type 1 diabetics in our ongoing clinical trials who received BCG prior to 2020 have been protected from the symptoms of COVID-19 infection.
“As we look forward to 2021, we need to raise the funds to start the pediatric type 1 diabetes trial and maximize the data from the ongoing trials.  Enclosed please find our new brochure with updates from the lab.  Thank you so much for all of your support!

Speaking of Health and Wellness…

Origin of the coronavirus SARS-CoV-2 by Amy Rogers

“I am suddenly seeing a lot more chatter and innuendo suggesting, or flat-out accusing, that SARS-CoV-2 came from a Chinese laboratory.

“Before you spread these rumors, consider these things.

“First, keep clear in your mind the difference between two different accusations:

  1. That China (or insert your favorite enemy here) created or genetically engineered this new virus for use as a bioweapon
  2. That a laboratory studying coronaviruses had an accident or security breach resulting in the escape of one of those viruses into the community

“#1 should leave evidence in the genetic sequence of the virus. As I blogged previously, experts say there is no such evidence in the genome of SARS-CoV-2. So as far as I am concerned, #1 is false. People say it, share it, believe it for the same reason all conspiracy theories find traction: people are afraid, and pinning blame on powerful dark forces gives a sense of control.

“So let’s talk about #2.

“Fact: there is a biosafety level 4 (highest level) virology research lab in Wuhan. Fact: this facility is well-known for its research on coronaviruses. Fact: some of the research there involves going into caves and other places where wild bats live, collecting bat guano, and studying viruses found in bats. The lab would definitely have both live and frozen specimens of a variety of coronaviruses.

“BSL-4 laboratories are explicitly designed to isolate the most dangerous microorganisms known—agents that are deadly, and have no vaccine or treatment. Is it possible that an accident could occur, and a worker could be exposed? Of course. Is it possible that an employee intentionally breached protocol for some reason, and brought a virus into the community? Of course it is possible.

“But is there evidence of this, or mere coincidence? For myself, I don’t spread rumors without evidence.

“Apparently not everyone is like me. Here’s what happened this week.

“On Tuesday, American’s highest-ranking military officer, Gen. Mark Milley, chairman of the Joint Chiefs of Staff, weighed in on the speculation that the origin of SARS-CoV-2 is not natural. The general’s exact quote was,

“At this point, it’s inconclusive although the weight of evidence seems to indicate natural {origin}.”

“Two major news organizations both covered the story. In the body of their articles, both reported the same basic information. But they chose very different emphases.

Headline A: U.S. Military Says Coronavirus Likely Occurred Naturally but Not Certain

Headline B: Sources believe coronavirus originated in Wuhan lab as part of China’s efforts to compete with US

“I would add that in article B, the “sources” who “believe” the virus came from the Wuhan lab are unnamed.

“I’m not interested in the agenda behind this spin. I’m interested in the scientific facts of how this new zoonotic (animal) virus found its way from bats into the people of Wuhan. There are countless plausible ways.

“An accident at the Wuhan Institute of Virology is one possibility. Evidence is lacking.

“An intermediate animal host such as pangolin at the Huanan Seafood Wholesale Market is another. Evidence is admittedly weak. Although the first recognized COVID-19 disease cluster was centered on the market, the first human cases (probably in November, as first official case was Dec. 1) might have brought the virus into the market rather than the other way around.

“The list of other possible routes is nearly infinite. Maybe it was some poor kid playing in the dirt outside a bat cave. A wealthy Wuhan citizen doing something weird with a bat for traditional Chinese medicine. Wildlife or a pig slaughtered in somebody’s back yard.

“The key point is, we may never know for sure. Uncertainty makes us uncomfortable, but don’t let that drive you to a false certainty. In the absence of proof, carefully examine your own worldview, what biases you have, that encourage you to “believe” one possible truth over another.

“In the end, I’d like to emphasize that we have long expected a virus like this to emerge naturally. (Even Hollywood knew: see the movie Contagion.) We have previous examples: see SARS-CoV-1, and MERS, zoonotic coronaviruses that jumped into humans naturally. And I can guarantee that another virus, and another, and another, will make this leap on their own without any laboratories or conspiracies in the future.

“(If you’d like to learn more about the science of how a virus jumps species, see my February treatise on the coronavirus.)

April 13, 2020 Monday Morning This Article Grabbed My Attention…

…”Stuck at home with no books to read? Here are 6 solutions.”

stuck at home with no books

“Different parts of the U.S. are experiencing different levels of shutdown, but one thing is universal: Books make staying at home a much better experience.

“But what if your bedside stack of reading material is down to its last book? And now you can’t reach the place you normally get books or spend time with the friend with whom you trade books?

“Don’t despair, dear readers. Here are five ways to get books instantly through Amazon or Audible, all of which require only a mobile phone or tablet.

“Plus I have one bonus suggestion at the very end that will take quite a bit longer than “instantly” but might change your life….

“Prime Reading. Prime Reading offers thousands of e-books and magazines that are free to download for Amazon Prime members. Browse through the books available in Prime Reading, download the Kindle app to your phone or tablet, and then download the books you want to read. The choices are constantly changing, but at the moment a few highlights include Margaret Atwood’s The Handmaid’s Tale, K.F. Breene’s Sin & Chocolate, and a cornucopia of Dean Koontz suspense novels. There are e-books for kids who are comfortable reading on phone or tablets, including Rick Riordan’s The Lost Hero and the Frozen junior novel.

“Kindle Unlimited. Amazon’s Kindle Unlimited offers its members unlimited access to download more than a million books and magazines. Right now Kindle Unlimited is offering a 30-day free trial for its subscription service. There are so many titles available in Kindle Unlimited, how to pick what to read first? You can start with our recent articles on Women’s History Month and World Storytelling Day that feature books in Kindle Unlimited. Or when you Search on Amazon in the Kindle store, make sure you check the option for “Kindle Unlimited Eligible.” (On your web browser, you will find the checkbox on the left side of the screen. On your Amazon app, you will find the checkbox as an option under “Filters.” The Kindle Unlimited Eligible option only shows up when searching titles within the Kindle store, please note.)

“There are many, many other ways to find Kindle books you’ll love. If you have a careful eye on your bank account, check out Kindle Daily Deals, which spotlight great reads on sale. And Amazon First Reads offers one Kindle book per month for only $1.99 (or for free if you’re an Amazon Prime member) from a selection of eight titles.

“Audible. The master in the audiobooks arena (and also an Amazon company), Audible very likely has the audiobook version of whatever book you want to read. And audiobooks can resonate in ways that reading words do not. For instance, I cannot think of Jim Butcher’s Dresden Files novels without remembering James Marsters’s growly voice, or of the Harry Potter series without hearing award-winning narrator Jim Dale. While you can purchase audiobooks a la carte, a monthly Audible membership also includes two of their amazing Audible Originals. (I recently painted my bathroom while listening to the Audible Original A Grown-Up Guide to Dinosaurs, and it made the hours fly by.) But wait: There’s more! Audible just launched Audible Stories, a collection of free audiobooks that are aimed at kids from toddlers to teens but also includes classics for readers of all ages. Download the Audible app to get started.

“Here’s the not-instantaneous solution I mentioned earlier in this article: Write your own book. Or poem. Or short story. Or graphic novel. Just start writing and see where it takes you. Most authors have first or second or third careers before they start writing, so don’t think you need a master’s degree in literature or have to go on a writers’ retreat to be worthy of putting a pen to paper (or fingers to the keyboard). We all have stories inside of us. Take this opportunity to let them out.

Why Does Insulin Cost So Much?

“8 Reasons Why Insulin is so Outrageously Expensive”

https://www.t1international.com/blog/2019/01/20/why-insulin-so-expensive/

“Why does insulin cost so much to patients in the USA and around the world? Why is insulin, a widely sold drug of which most forms are now off-patent, so incredibly expensive? These are simple questions, but ones with a number of complicated answers. This post will break some of those answers down and point you in the direction further reading if you want to dive deeper.

“1. Only 3 Companies Control 90% of the Global Insulin Market

“The ‘big three’ insulin producers – Eli Lilly, Novo Nordisk and Sanofi – dominate more than 90% of the world insulin market by value. Often only one of these companies supplies insulin in a country, which means they more or less hold a monopoly there and can set prices as they wish. In some countries, notably China and India, there are domestic insulin companies that can help drive down the price. This means we need more companies in markets like the USA to help bring prices down. We’ll touch on that a bit further down the list.

“2. No Generic Insulin

“When it comes to the question of generic insulin, we are faced with another complicated issue. Insulin is a therapeutic biological product (or ‘biologic’), rather than a chemically synthesized molecule. This means it cannot be made as generic in the same way as other drugs. Creating what is called a biosimilar is a lot more complicated and expensive than just duplicating a chemical molecule. There is little market incentive to produce biosimiliars because it costs nearly as much as making new drug, and companies must go through all the approval stages and trials that a new drug is required to go through. Not to mention, current biosimilar insulins on the market – primarily produced by the ‘big three’ – have only reduced the price by about 10-15%. For more on biosimilars and the 2018 FDA announcement read this and this.

“3. Pay-for-Delay Schemes & Lawsuits

“A ‘Pay for delay’ agreement is a patent dispute settlement in which a generic (in the case of insulin, a biosimilar) manufacturer acknowledges the original patent of a pharmaceutical company and agrees to refrain from marketing its product for a specific period of time. In return, the company receives a payment from the patent-holder. This means it is actually legal for one insulin producer to pay another one not to enter the market. A few years ago the company Merck announced plans to sell a biosimilar version of Sanofi’s Lantus. Sanofi sued, and eventually Merck announced that it was no longer pursuing it’s biosimilar, presumably due to payments from Sanofi to stay away. If Pay for delay schemes don’t work, the ‘big three’ can still sue other players, prolonging processes and pushing players out of the market because of legal fees and time-wasting. All of these are win-wins for companies, and lose-lose for patients.

“4. Patents

“Why aren’t we seeing more companies making insulin? There are many reasons for this, but patent evergreening is a big one. Patents give a person or organization a monopoly on a particular invention for a specific period of time. In the USA, it is generally 20 years. Humalog, Lantus and other previous generation insulins are now off patent, as are even older animal based insulins. So what’s going on? Pharmaceutical companies take advantage of loopholes in the U.S. patent system to build thickets of patents around their drugs which will make them last much longer (evergreening). This prevents competition and can keep prices high for decades. Our friends at I-MAK recently showed that Sanofi, the maker of Lantus, is no exception. Sanofi has filed 74 patent applications on Lantus alone, that means Sanofi has created the potential for a competition-free monopoly for 37 years.

“5. Politics

“Companies are not in the habit of throwing money away, and they are not in the habit of staying out of politics. Eli Lilly, Novo Nordisk, and Sanofi collectively rake in several billions of dollars in profits. That’s not millions, but billions – with a B. We know they spend millions on marketing, but they also spend millions on lobbying politicians and donating to our decision-makers so that they keep quiet about price gouging. Check if your representatives receive contributions from one of the ‘big three’ insulin manufacturers or any pharmaceutical company. Chances are, they do. Not to mention, the revolving door between pharma companies and US Government positions. Our current secretary of Health and Human Services was previously an Eli Lilly executive. Obviously, his interests are not with people, but with power. This is why independent patient voices are so important.

“6. Price Fixing

“These Business Insider graphs pretty much say it all.

Several lawsuits alleging some form price-fixing are currently in the works. You can read more here and here.

“7. Pharma Marketing Schemes

“Physicians in the United States and some other countries are allowed to collect fees from pharmaceutical companies for talks, advice, and more. Supposedly, these are to compensate physicians for their expertise and time. However, they can create loyalty to a company and may influence prescribing habits – a belief shared by some pharmaceutical salespeople. In some countries like India, physicians are allowed to sell and profit off insulin directly through patients, or through pharmacies they themselves own, cutting out middlemen and the retail pharmacies. Thus, they lose the incentive to find the lowest price insulin for their patients. Insulin companies also focus on ‘insulin-starts’, or the insulin the physician diagnosing patients begins with. As patients are reluctant to change, a number of marketing and financial incentives are employed to influence this decision.

“8. Payment for Influence (or Silence)

“Many major key opinion leaders, influencers, and patient advocacy organizations take pharma cash. For example, the two biggest diabetes organizations – The American Diabetes Association and The Juvenile Diabetes Research Foundation – have accepted huge sums from insulin manufacturers. Other groups were actually created by money from the ‘big three’, like the World Diabetes Foundation which is funded by Novo Nordisk, and other supposed advocacy groups that are actually doing pharma’s bidding, or at least are highly influenced by them. If this issue is important to you, check the funders of an organization you want to support, and if it’s not transparent, you can ask if they take industry money.

“What Can be Done?

“Patients are speaking out about these issues all around the world. In the USA where prices have skyrocketed especially, T1International Chapters are being formed where patient advocates are educating and pushing for policy change. You can learn more about Chapter here and find more information and action related to the insulin price crisis here. Whatever you do, wherever you are – don’t stay silent.”
