As the second wave of the pandemic engulfs us and the world works at warp speed to develop vaccines and therapies to respond, the importance of regenerative medicine has never been higher. Since 2017, Goldman Sachs has touted the sector as one of the most compelling areas for venture capital investment. With billions of dollars of global government spending being poured into the search for vaccines and therapies to respond to the novel coronavirus, and with the FDA having now granted approval to the first vaccines based on CRISPR mRNA gene-editing technologies, business models based on regenerative medicines are commanding record values. Despite the flood of cash into regenerative medicine, legal and ethical considerations will continue to cause much controversy.
What is Regenerative Medicine?
Regenerative medicine ultimately accelerates the human body's healing process. It is an area of biomedical sciences that involves medical treatments to repair or replace damaged cells, tissues, or organs. Instead of merely focusing on the symptoms, regenerative medicine uses cellular therapies, tissue engineering, medical devices, and artificial organs to improve people's health. For example, stem cell therapies, tissue grafts, and organ transplants are all part of regenerative medicine.
Today, cellular and acellular regenerative medicines are often used in clinical procedures such as cell, immunomodulation, and tissue engineering therapies. They have the potential to effectively treat many chronic diseases, including Alzheimer's, Parkinson's and cardiovascular disorders, osteoporosis, and spinal cord injuries.
"A small number of unscrupulous actors," according to the FDA, however, "have seized on the clinical promise of regenerative medicine" to offer patients unproven treatments. The FDA and other regulators are challenged to provide assurances of safety for these therapies without stifling development, as well as to approve treatments based on manipulation of stem cells derived from human and animal embryos given the ethical issues involved.
In the future, stem cell research will play an increasingly outsized role in regenerative medicine techniques. In November 2020, voters in California narrowly passed Proposition 14, a referendum to approve $5.5 billion in new government funding for stem cell research. Other governments around the world are doing the same.
Today, the growing prevalence of chronic medical ailments and genetic disorders across the globe is a primary factor driving the regenerative medicine industry's growth, according to the "Regenerative Medicine Market: Global Industry Trends, Share, Size, Growth, Opportunity and Forecast 2020-2025." The increasing aging population, prone to various musculoskeletal, oncological, dermatological, and cardiological disorders, is a key growth driver. Widespread adoption of organ transplantation is another contributing factor to this growth in market share. The current pandemic that began in January 2020, however, has changed the paradigm for regenerative medicine.
Market applications are burgeoning. Regenerative medicine can prevent and cure disease through effective vaccines and efficacious therapies. It can minimize the risk of organ rejection post-transplant and speed recovery. Technological advancements in cell-based therapies, such as the development of 3-D bioprinting techniques and the adoption of artificial intelligence in the production of regenerative medicines, are also stimulating growth. These advancements also facilitate dermatological grafting procedures to treat burns, bone defects, and skin wounds. Other factors, including extensive research and development activities in medical sciences and improving healthcare infrastructure, are also predicted to drive the market even further.
According to the Alliance for Regenerative Medicine, there are approaching approximately 1,000 companies focusing on this evolving area worldwide. These new companies are focusing on gene therapy, cell therapy and tissue engineering therapeutic developers. More than half of these companies are in North America, followed by almost a quarter in Europe and Israel and approximately 20% in Asia. More than 50% of these companies are focusing on cell therapy and gene therapy.
Investment from VCs
From 2014 to 2019, the global regenerative medicine market experienced a nearly 16% CAGR. Companies involved in gene and cell therapies as well as other regenerative medicine areas raised $4.8 billion during the first half of 2019, including $2.6 billion in the second quarter. Meanwhile, companies in Europe and Israel saw an acceleration of fundraising, with $1.3 billion amassed in just the first half of 2019, representing a 17% increase over the same period in 2018. Project Warp Speed has attracted billions of dollars of U.S. government spending, and similar efforts are ongoing in China, Russia, the European Union and among other major powers. Consequently, regenerative medicine has never before benefited from such a combination of public and private investment.
Ethical and Legal Issues
Whenever the viability and quality of human life are at stake, ethical and legal considerations always arise.
The modern ethical controversy surrounding regenerative medicine began in 1998 when research scientists at the University of Wisconsin succeeded in deriving and growing stem cells from early-stage human embryos. Ethicists and right-to-life activists protested that scientists were taking away human life (embryos) to conduct scientific experiments. Left unchecked, so the argument went, doctors could usurp nature and play "God" by developing the power to create and terminate life. A society where human life could be fundamentally perverted by medicine conjured up comparisons to Nazi Germany and Frankenstein. In 2001, then-U.S. President George W. Bush cut off federal funding for any research involving newly created embryonic stem cell lines, but agreed to continue funding research on 60 existing stem cell lines, "where the life and death decision ha[d] already been made." The State of California responded in 2004 and again in 2020 with voter-approved programs directing billions of funding into stem cell research, making the region the global hub of regenerative medicine.
The use of human-derived embryonic stem cells, or animal-derived stem cells, continues to cause much controversy among ethicists and society at large. Some fear the risks of enrolling humans in experimental stem cell studies. Others fear the use of organs from human-animal chimeras in transplantation.
While these techniques have the potential to cure disease and save lives, they also have the potential to forever alter the nature of life as we know it and fundamental aspects of our society.
In the United States, legal jurisdiction for regulating regenerative medicine on a federal level lies with the FDA and in a patchwork of state laws, R&D funding programs and non-binding, NGO-promulgated statements of policy. The main responsibility of the FDA is to protect the public from dangerous products and ensure its safety, including overseeing medications for humans and animals, vaccines, and more.
During the Trump Administration, the FDA has largely focused on enabling developers to gain product approvals through a less burdensome and costly process. In numerous policy statements, the FDA under President Trump has deferred questions about the efficacy of new regenerative health products to the free markets, so long as they posed no serious safety or toxicity concerns.
The U.S. federal government is now transitioning to an administration led by President-elect Biden. The president-elect has spent many years advocating for increased R&D funding and going for "moonshots." With a new mandate from the U.S. electorate to address the coronavirus, more money will be earmarked for regenerative medicines and stem cell research. How this will affect the release of new products into the market remains to be seen.
Where Do We Go From Here?
Regenerative medicine is poised to change the way we live, work and interact like never before. The fourth industrial revolution is upon us. CRISPR gene-editing technologies, facilitated by quantum-computing capabilities at the edge of a computer network powered by 5G telecommunications bandwidths, artificial intelligence and machine learning, have changed the game for regenerative medicine. We can foresee a day when those suffering from paralysis regain movement, when a damaged heart reverses course through regeneration, and when a diagnosis of Alzheimer's Disease no longer means neurodegeneration. What a wonderful day that will be.
