A drug maker in Canada has launched a new, cheaper version of a drug used to treat Alzheimer’s and Parkinson’s, a move that could save lives and ease the burden of the disease.
CVS Health’s “Cancer-fighting” CTE-21 drug, called CTE, is designed to slow the progression of the degenerative brain disease and has been available in clinical trials in Canada for more than a year.
The company plans to start marketing it in the U.S. and Europe this fall.
But this week, the company revealed that it has halted testing on the drug in the United States because of concerns that the FDA’s approval process could not be properly vetted.
CVCX, which was acquired by CVS in 2014 for $11.2 billion, said it had suspended its drug testing in the states for now, but that it would resume testing when its new U.K. trials are complete.
CVAX, on the other hand, is still undergoing FDA approval in the countries where it was originally approved.
CVE, the first drug to target the human T-cells, is being used to slow CTE in Alzheimer’s patients and Parkinsonism patients.
But CVCV and CVE are also being tested on a variety of different patients with similar disease outcomes, which makes it hard to know if the drugs have the same benefits as they did before.
FDA recently rejected CVCVI, the most expensive drug to date, for its ability to slow progression of Alzheimer’s.
The drug was approved by the U-K.
government in March.
The FDA said CVCVAX has been used for about 2,000 patients, which is a tiny fraction of the estimated 300,000 Alzheimer’s cases in the country.
But the drug has been in clinical use for more years than CVCVCX.
“There is a real risk that if these drug candidates don’t get FDA approval, there is no point to developing them,” said Scott Gaffney, an associate professor at the University of Pennsylvania’s Miller School of Medicine and a former FDA commissioner.
“It’s not the most efficient way to do things, but there’s an inherent risk of this sort of thing happening.”
CVCVS said it is taking a “consensus approach” to finding the best drug for the patients it plans to test.
The agency will not be able to approve any drug that is approved in more than half of the countries it tested it in, and it will not consider any drug if it’s approved in fewer than 10 countries.
CVRX was originally developed for Alzheimer’s, but its use in Parkinson’s has not been well studied, and the drug could have significant side effects in people with the disease, Gaffny said.
In some cases, people with Parkinson’s may be more vulnerable to the side effects of the drug, which are similar to those of a few other drugs that have been approved in the past.
The Drug Enforcement Administration is also still investigating CVCVE’s safety, and is working with the FDA and other federal agencies to determine whether the drug is safe.
CVI, which has been approved by European regulators for its anti-inflammatory and anti-cancer properties, was first approved by U.N. agencies for use in people who are in severe pain.
It was recently approved in Australia for use to treat depression and anxiety, and has received approval in Europe, China and the United Kingdom.
CVD, which includes both Alzheimer’s disease and Parkinsonís, is the third most common form of dementia in the world.
CVP, the next-costliest drug, was approved in 2011 for treating Parkinson’s in people in advanced stages of the illness.
It is still being tested in patients in the Netherlands, where it has been shown to be effective.
But Gaffey said CVP has never been approved for the treatment of Alzheimerís.
And the FDA is continuing to review CVCVP for safety.
The new drugs have to go through a “pre-market review” process before they can be approved for sale in the market, and CVS has until December 31 to complete the review.
The CVC-21 and CVCVR drugs were initially developed by the University in Cambridge, UK.
CVVS is a privately held company, but is also part of the larger CVS group, which also includes Johnson & Johnson, Amgen and Novartis.
CTV News reached out to CVS for comment, but did not receive a response by the time of publication.
Cvs said it was unable to provide additional information on the delay in the CVAx and CVRx drugs, because the FDA review process has not yet been completed.
CVMX, CVCVD and CVA are the first two drugs to target CVCTE, which affects millions of people in the global U.P., according to the Alzheimer’s Association.
There are approximately 10 million people with Alzheimer’s in the developing world.
