Why Stem Cell Advocates Texans for Cures say “Right to Try” Legislation Should be Fought

Texans for Cures 

This week in Washington DC a delegation from the stem cell advocacy group Texans for Cures is meeting with members of Congress from both parties. The focus of the meetings are three bills promoting “Right to Try” legislation. Supporters of the bills say they will empower patients battling terminal illness. Texans for Cures say, quite the contrary, that these laws will endanger patients. In this guest blog, Texans for Cures explain why they feel these laws are bad.

In 2014, the Goldwater Institute published a policy report titled, “Everyone Deserves the Right to Try: Empowering the Terminally Ill to Take Control of their Treatment.”[i] The report calls for states to pass “Right to Try” legislation as a means to reclaim patients’ medical autonomy and right to determine their own medical treatment.

This policy recommendation is built on the theory that the Food and Drug Administration (FDA) should not be able to restrict terminal patients’ access to potentially life-saving treatments so long as the treatment has been tested for basic safety. While this idea may seem immediately appealing, the policy undermines medical research in several ways that are harmful to the development of new treatments.

Texans for Cures opposes this legislation because it harms the sound development of treatments for future patients on the mere chance that it may provide relief to current patients that have received a terminal diagnosis. In short, Right to Try policies ignore the attendant risks and overemphasize the potential benefits.

“Right to Try” Model Legislation and State Enacted Variants

The Goldwater Institute’s policy report included model legislation for interested legislators, which it summed up as follows:

Simply stated, Right to Try allows a patient to access investigational medications that have passed basic safety tests without interference by the government when the following conditions are met:

  1. The patient has been diagnosed with a terminal disease;
  2. The patient has considered all available treatment options;
  3. The patient’s doctor has recommended that the investigational drug, device, or biological product represents the patient’s best chance at survival;
  4. The patient or the patient’s guardian has provided informed consent; and
  5. The sponsoring company chooses to make the investigational drug available to patients outside the clinical trial.

Since the Goldwater Institute published this policy report in 2014, 33 states have enacted Right to Try laws.[ii] These laws contain minor variations from the model legislation, but each operates similarly to limit the FDA’s oversight roll.

Right to Try is Loosely Grounded in the Constitution and May Require Federal Action

Due to the fact that these laws may infringe on the FDA’s authority over drug development and distribution, the policy report attempts to ground Right to Try in one’s constitutional right to liberty. This constitutional underpinning is loose and is not firmly supported by Supreme Court precedent.[iii] With the constitutional basis of Right to Try resting on a weak foundation, it is important for Right to Try proponents to pass a complimentary Right to Try statute on the federal level in Congress.

There are three bills actively working through the Congressional process that would prohibit the FDA or any other federal agency from interfering with a patient’s Right to Try: H.R. 878 by Representative Biggs,[iv] H.R. 2368 by Representative Fitzpatrick,[v] and S. 204 by Senator Johnson.[vi] Each of these bills shares three common provisions, while H.R. 2368 has two additional provisions:

Common Provisions:

  1. Prohibition on federal action
  2. No liability
  3. No use of outcomes

Provisions Unique to H.R. 2368:

  1. Manufacturers are not required to make treatments available
  2. Permits manufacturers to receive compensation or recover costs

All three of the federal bills would remove the FDA’s ability to intervene in state Right to Try programs. They also create a liability shield for any producer, manufacturer, distributor, prescriber, dispenser, possessor, or user participating in the program. And finally, each prohibits the use of outcomes from patients participating in Right to Try as a criteria for FDA review of the treatment. This means that harmed patients would have limited or no legal recourse, and the FDA may need another Act of Congress to grant them the authority to intervene in any programs that prove to be dangerous. However, it may be difficult to know if these programs are harming patients or not, because the bills do not provide any mechanism for tracking outcomes and using that information for oversight.

Each bill is drafted in a way that would remove FDA oversight authority and would allow states to proceed with Right to Try policies and grants states broad discretion to tailor these programs without federal oversight. However, H.R. 2368 contains two additional provisions that would compliment and potentially override state statute. First, the bill gives manufacturers the authority to deny patients access to investigational treatments, which is consistent with the Goldwater Institute’s model legislation. Second, the bill allows manufacturers to receive compensation or recover costs involved in making the drug available to patients. This second provision is particularly problematic in that it would allow manufacturers to charge patients for unproven treatments unless they were explicitly prohibited from doing so by state law.

How Right to Try Laws Structurally Harm the Research Process

Right to Try laws create a number of problematic incentives and penalties that would likely harm the long term development of new therapies. First and foremost, under Right to Try, patients will be able to bypass the clinical trial process, request investigational treatments, and pay the cost of the drug, rather than enter into a clinical trial. Given that clinical trials may involve the use of placebos, Texans for Cures is concerned that patients may choose to exercise Right to Try rather than participate in a clinical trial, because under Right to Try the patient avoids the possibility of receiving a placebo.

Additionally, there is no mechanism in the proposed bills for tracking outcomes of patients participating in Right to Try, and there is no mechanism for government intervention if Right to Try proves to be unreasonably risky.

Right to Try seeks to shield all participants from liability, meaning that patients who are harmed will have limited or no legal recourse, even if manufacturers or physicians are negligent. Furthermore, Right to Try laws typically allow manufacturers to recover the cost of manufacturing the treatment for participating patients, but cost is not defined. Does cost include the cost of research and development or is it exclusively the cost of creating that specific treatment? The ambiguity surrounding this term is a cause for concern, because companies may be tempted to use this ambiguity to cover a broader sets of costs than the authors intended.

Conclusion

Texans for Cures opposes this legislative effort because the program could potentially harm patients and, if it does, the law does not provide adequate safeguards or remedies. Additionally, the law does not require any monitoring of outcomes and is therefore unscientific in its approach to treatments that are currently undergoing clinical research.

The FDA is already working to ease the burdens associated with Expanded Access programs, which achieve the end that Right to Try desires: providing access to research drugs for terminal patients. The difference is that Expanded Access has additional safeguards and a mechanism for FDA intervention if treatment is found to be dangerous or harmful to the clinical trial process.

Finding scientifically sound treatments for patients in need is the primary concern of Texans for Cures. Texans for Cures sympathizes with, and its members have similarly experienced, the pain of losing loved ones. The hope and emotion involved in Right to Try laws is not to be taken lightly, but it is precisely because strong emotions can cloud our judgment that we, as a society, must approach the clinical trial process with a clear mental state. Texans for Cures believes that Right to Try will harm the long term development of new treatments and therefore asks for your help in fighting this legislative effort.

3 The Goldwater Institute’s sole source for constitutional grounding for this law comes from a concurrence by Justice Douglas in Doe v. Bolton, 410 U.S. 179, 218 (1973), where he noted that individuals have a “right to care for one’s health and person.” The Goldwater Institute appears to recognize the precarious footing of their model legislation, stating in their policy report, “Although the right of terminal patients to access investigational medications has not yet been recognized by the Supreme Court, it is consistent with and can be supported by existing precedent.”

Stories that caught our eye: An antibody that could make stem cell research safer; scientists prepare for clinical trial for Parkinson’s disease; and the stem cell scientist running for Congress

Antibody to make stem cells safer:

There is an old Chinese proverb that states: ‘What seems like a blessing could be a curse’. In some ways that proverb could apply to stem cells. For example, pluripotent stem cells have the extraordinary ability to turn into many other kinds of cells, giving researchers a tool to repair damaged organs and tissues. But that same ability to turn into other kinds of cells means that a pluripotent stem cell could also turn into a cancerous one, endangering someone’s life.

Now researchers at the Agency for Science, Technology and Research (A*STAR) in Singapore may have found a way to stop that happening.

When you change, or differentiate, stem cells into other kinds of cells there will always be some of the original material that didn’t make the transformation. Those cells could turn into tumors called teratomas. Scientists have long sought for a way to identify pluripotent cells that haven’t differentiated, without harming the ones that have.

The team at A*STAR injected mice with embryonic stem cells to generate antibodies. They then tested the ability of the different antibodies to destroy pluripotent stem cells. They found one, they called A1, that did just that; killing pluripotent cells but leaving other cells unharmed.

Further study showed that A1 worked by attaching itself to specific molecules that are only found on the surface of pluripotent cells.

In an article on Phys.Org Andre Choo, the leader of the team, says this gives them a tool to get rid of the undifferentiated cells that could potentially cause problems:

“That was quite exciting because it now gives us a view of the mechanism that is responsible for the cell-killing effect.”

Reviving hope for Parkinson’s patients:

In the 1980’s and 1990’s scientists transplanted fetal tissue into the brains of people with Parkinson’s disease. They hoped the cells in the tissue would replace the dopamine-producing cells destroyed by Parkinson’s, and stop the progression of the disease.

For some patients the transplants worked well. For some they produced unwanted side effects. But for most they had little discernible effect. The disappointing results pretty much brought the field to a halt for more than a decade.

But now researchers are getting ready to try again, and a news story on NPR explained why they think things could turn out differently this time.

Viviane Tabar, a stem cell researcher at Memorial Sloan Kettering Cancer Center in New York, says in the past the transplanted tissue contained a mixture of cells:

“What you were placing in the patient was just a soup of brain. It did not have only the dopamine neurons, which exist in the tissue, but also several different types of cells.”

This time Tabar and her husband, Lorenz Studer, are using only cells that have been turned into the kind of cell destroyed by the disease. She says that will, hopefully, make all the difference:

“So you are confident that everything you are putting in the patient’s brain will consist of  the right type of cell.”

Tabar and Studer are now ready to apply to the Food and Drug Administration (FDA) for permission to try their approach out in a clinical trial. They hope that could start as early as next year.

Hans runs for Congress:

Keirstead

Hans Keirstead is a name familiar to many in the stem cell field. Now it could become familiar to a lot of people in the political arena too, because Keirstead has announced he’s planning to run for Congress.

Keirstead is considered by some to be a pioneer in stem cell research. A CIRM grant helped him develop a treatment for spinal cord injury.  That work is now in a clinical trial being run by Asterias. We reported on encouraging results from that trial earlier this week.

Over the years the companies he has founded – focused on ovarian, skin and brain cancer – have made him millions of dollars.

Now he says it’s time to turn his sights to a different stage, Congress. Keirstead has announced he is going to challenge 18-term Orange County Republican Dana Rohrabacher.

In an article in the Los Angeles Times, Keirstead says his science and business acumen will prove important assets in his bid for the seat:

“I’ve come to realize more acutely than ever before the deficits in Congress and how my profile can actually benefit Congress. I’d like to do what I’m doing but on a larger stage — and I think Congress provides that, provides a forum for doing the greater good.”
