What are the only stem cell therapy conditions currently approved in Canada?

As of 2020, Canada has approved a total of 3 cellular therapeutic products! These include the use of stem cells for the treatment of acute lymphoblastic leukemia (ALL), Adult B-cell Lymphoma, and Graft V Host disease.

Most approved therapies use hematopoietic stem cells (HSC). Bone marrow, blood, and the umbilical cord all contain HSCs. HSCs mature into cells that make up the blood and immune system. This makes them perfect for the treatment of conditions such as leukemia, lymphoma, and blood disorders. We can now treat over 80 medical conditions with the HSCs collected from cord blood.

Three cellular therapeutic products do not sound like enough. To understand why there are a few approved stem cell therapies on the market we must first ask the following questions:

How do stem cell therapies get approved in Canada?

In Canada, all cell therapies are considered drugs under the Food and Drugs Act. They must be authorized by Health Canada to ensure they are safe and effective before they are offered to Canadians. All other treatments are experimental or unproven. Canadians should refer to Health Canada’s Drug Product Database [2]and Clinical Trials Database [3].

How do stem cell therapies work?

Stem cell therapies can work in one of two ways to reduce the severity of a disease or disorder. The first is a stem cell transplant, and the second one is to act as a target for a drug or other biologic. A stem cell transplant is when existing stem cells in your body, which have been damaged or destroyed by disease, are replaced. The stem cell transplant can either be allogeneic or autologous.

  • An allogeneic transplant involves a person (donor) giving his/her stem cells to another person (recipient).
  • An autologous transplant involves a person giving his/her stem cells, which are then manipulated or processed and reintroduced to the same person.

Stem cells can also act as a target for a drug or other biologic. In this type of treatment, the drug activates a desired response from the stem cells that already exist in the patient’s tissues or organs.

The future of stem cell treatments is dependent on Induced Pluripotent Stem Cell (IPSC) technology. This technology involves reprogramming skin or blood cells into an embryonic-like pluripotent state. Cells in a pluripotent state can generate any other type of cell in the human body.

The promise of stem cells lies in the clinical trials

Unapproved therapies are those that have gone through the safety and efficacy process through clinical trials. Clinical trials are research studies performed in people to find out if a new treatment is safe and effective. There are approximately 1300 trails underway that use HSCs to address conditions such as[5]:

  • Cerebral Palsy
  • Diabetes
  • Multiple Sclerosis (MS)

Mesenchymal stem cells (MSCs), found in cord tissue and placental tissue, can differentiate into many types of cells and tissues. These include cartilage, skin, bone, and fat cells. There are more than 300 major MSC clinical trials underway worldwide for conditions such as:

  • Spinal Cord Injuries
  • Lung Cancer
  • Type 1 diabetes
  • Stroke

Finally, IPSC based clinical trials have been at the forefront of stem cell therapeutics. In 2019, heart surgeons used IPSC-derived cardiomyocytes to treat patients with heart disease. There is hope to treat patients with Parkinson’s Disease by 2022[6].

With so many ongoing trials, those who choose to invest in cord blood, placental tissue banking or live cell tissue banking are not just investing in the medicine of today, but recognize the future of stem cell and regenerative medicine.

The Best Time to Bank Your Cells Is Today

Your own live cells are the single most valuable resource for future medical treatment. Thanks to the advances in the field of regenerative medicine, scientists now have the tools to use them to theoretically treat any disease imaginable. One thing to keep in mind is that the sooner you bank your cells, and shield them from aging, the greater their therapeutic potential will be.

While it is certainly exciting, trying to stay up to date with the constant advancements of science and technology can be overwhelming. There is just too much information out there. To make matters worse, the language researchers use while publishing their findings in scientific journals, can be unintelligible.

Fortunately, you don’t need an MD or PhD to know that we are on the brink of a medical revolution. You may have heard about regenerative medicine. It is a field of study concerned with the reengineering of human cells to form tissues and organs. Its goal is to develop treatments for an endless variety of medical conditions. This field is expanding at a rapid pace. It has the potential to completely transform our approach to health and medicine in general.

The future of medicine will be cell-based

At the center of this revolution is the ability to take a sample of a person’s cells and transform them into whatever tissue or organ a patient requires for treatment. For a long time, sourcing these cells proved to be a difficult task. Researchers could not simply take any cell in the body since, by the time they have matured, cells become differentiated and specialized. Only stem cells retain their potential to become any type of cell required.

There are a few viable methods of stem cell extraction, including bone marrow harvesting and liposuction. However, they are inconvenient, expensive, and painful for the patient. In addition, these types of stem cells were multipotent, but could not become any and every cell in the body. Thankfully, researchers John B. Gurdon and Shinya Yamanaka discovered a way to program mature cells to become pluripotent —they received the Nobel Prize in Medicine in 2012 for this discovery. What this means is that scientists can now take adult cells and make them behave like stem cells. This process restores their transformative potential.

Based on this finding, researchers at Acorn concluded that hair follicles are an effective source of cells for banking. They are therapeutically-capable and can be grown consistently in the lab. Their extraction is simple, convenient, affordable, non-invasive, and painless. You can either head to Acorn’s lab headquarters in Downtown Toronto to provide a sample or do it in the comfort of your home. If you order a live cell collection kit, all you have to do is pluck your own hairs, follow the instructions in the box and ship it back to Acorn for processing.

The right time to bank your cells

There is something to keep in mind if you are considering banking your cells: time is of the essence. As we age, our cells deteriorate. This means that their ability to function and perform their jobs slowly diminishes. The result is that they lose some of their therapeutic potential. Your cells at 20 years old are much better than at 50 —likewise, they are much better at 50 than at 80.

Should I bank my cells if I am over 50? Yes, absolutely. They are in a much better state now than they will be in the future. If you decided to bank them today and were to need them at 60, you will have shielded them from 10 years worth of damage. This is because at -190°C, cellular metabolism, and with it the aging process, stops. The best timepoint to bank your cells is today, regardless of age.

Take advantage of the information contained in your cells

What if I never require a procedure that involves stem cells? You will still benefit from next-generation analytics. Most people are familiar with DNA home testing kits. These tests capture dead cells from saliva that are unusable in cell therapy but can reveal ancestry. This is just one of the many layers of information contained within your cells. The other layers are only accessible through live cell collection. That is what Acorn offers.

Our DNA does not normally change, but there are many layers of information in our cells, including epigenetics, transcriptomics, proteomics, and metabolomics that are changing throughout our lives. Having a sample taken today allows you to plot the difference in these layers over time as new analytical tests become available. This can help predict what diseases you may face later in life. Equipped with this knowledge, you can modify your behavior and adopt healthier habits. This would help to increase your healthspan for as long as possible.

In the future, you will even have the possibility to have faulty genetic code edited out with tools like CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats). This mechanism is essentially ‘cut and paste’ for the human genome.

Thanks to a multitude of therapies currently in development, it will be possible to eradicate a latent disease long before the first symptoms appear. That is the promise of regenerative medicine and genetic engineering.

The bottom line is this: the sooner you take action and have your live cells cryopreserved, the better prepared you will be to take advantage of the revolution of regenerative medicine that is coming. It is the ultimate investment.

Cell Therapy in Canada: Striking the Right Balance Between Regulation and Innovation

When it comes to the development of new health technologies and drug treatments, we have to be patient. In fact, the stakes couldn’t be higher because not taking the correct approach, with proper oversight at each step, could have dire consequences, including injury — or even death. That’s why it can take years, even a decade, for new forms of medicine to be tested for safety and efficacy before they’re approved.

This is exactly why we need to take a science-based approach when it comes to regulating cell therapy treatment, or regenerative medicine, which will play a major role in the future of healthcare. According to the Mayo Clinic, patients who might benefit from these forms of treatment are extremely diverse, including those suffering from Type-1 diabetes, Parkinson’s, Alzheimer’s, burns, cancer and strokes, just to name a few. There is no shortage of excitement from physicians, scientists and patients.

While the benefits of cell therapy are promising, the regulatory and oversight framework in Canada will need to keep pace with advancements made in the sector on a global scale. According to the Alliance for Regenerative Medicine, there are 906 gene and cell therapy companies worldwide, with just over 1,000 clinical trials currently taking place. The industry is also growing rapidly. In 2018, the field raised $13.8 billion internationally, an increase of 73 per cent from the year before.

Recognizing this, Health Canada recently launched consultationswith stakeholders to “modernize its regulatory framework to meet the new demands of today’s increasingly complex health technology while still protecting the health and safety of Canadians.” The government should be applauded for reaching out and engaging with industry leaders, since taking a collaborative approach backed by informed expert opinion will ensure we foster innovation while upholding patient safety, which is the top priority.

As the founder of a company that does not administer cell therapy treatment but collects live cells and maintains them through cryopreservation for possible future therapeutic use, we fully support and encourage the development of new clinical trial regulations that can establish Canada as a world leader in regenerative medicine.

But this country isn’t alone when it comes to foreseeing the large-scale impact cell therapy treatment will have and the need to play regulatory catch-up with rapidly advancing technology.

Earlier this year, the Food and Drug Administration (FDA) in the United States announced plans to accelerate cell therapy approvals.The FDA expects it will receive some 200 investigational New Drug Applications, which are requests for authorization to administer an investigational drug to humans.

This increased focus on regenerative medicine has prompted the FDA to hire an additional 50 staffers to expedite the approval process. The fast-track process is not to be confused with final approval for use with the general public. Rather, it’s an “accelerated approval pathway may offer a faster route to approval for new treatments, including potentially curative benefits in significant, unmet medical needs.”

As with any new treatment in medicine, there will always be a debate on its future impact on patients. While there are differences of opinion regarding the timelines for regenerative medicine treatments, one thing is clear: The industry is growing on a global scale and the federal government has taken notice. Canadians should feel confident that Health Canada is taking the right steps in consulting with industry to ensure their safety is protected and that our nation remains a world leader in cell therapy innovation.

I believe that our own cells are the next currency in healthcare, opening up regenerative medicine treatments and next-generation analytics, and I am excited about the role Canada is taking in this bright future.
