FDA worried drug was risky; now reports of deaths spark concern

......

Nuplazid's review was being expedited because it had been designated a "breakthrough therapy" -- meaning that it demonstrated "substantial improvement" in patients with serious or life-threatening diseases compared to treatments already on the market. Congress created this designation in 2012 in an effort to speed up the FDA's approval process, which has long been criticized for being too slow. Around 200 drugs have been granted this designation since its creation.

Still, to recommend approval, the advisory committee would have to find that the drug's potential benefits outweighed its risks for its intended patients.

Some FDA officials concluded that Nuplazid's public health benefit was enough to merit approval of the drug. Their argument echoed the pleas of family members and caregivers like Tyne: It could possibly help patients with no other alternative. Several of the people who spoke said their loved ones had been transformed during the clinical trials, though some said there was no way for them to know whether they were on Nuplazid or a placebo.

But the physician who led the FDA's medical review, Dr. Paul Andreason, warned that patients taking the drug during the company's clinical trials experienced serious outcomes, including death, at more than double the rate of those taking the placebo. The company's limited testing, he said, had not convinced him that the benefits outweighed the risks.

'You have to take it seriously'
The committee voted 12-2 and recommended that the FDA approve Nuplazid for the treatment of Parkinson's disease psychosis based on a six-week study of about 200 patients. Three previous studies of the drug did not show that it was effective, Andreason said in his medical review, though they showed similar risk.

Even some committee members who voted in favor of the drug expressed reservations, according to the hearing transcript. "I guess I'm hoping that the risks are going to be small, and I think the benefits for some of these people who are very sick and whose families are affected by this, I think they're probably willing to take that risk," one physician stated. Another committee member said she wouldn't have voted for the drug's approval if there had been a safe and effective alternative on the market. A third made a "plea" to the FDA to "consider a large observational study so we can ensure that, once it goes into real-world use, that the benefits will outweigh the risks."

It hit the market in June 2016. As caregivers and family members rushed to get their loved ones on it, sales climbed to roughly $125 million in 2017.

.....

Shortly after the drug's release, patients' family members, doctors and other health care professionals started reporting "adverse events" possibly linked to the medication -- including deaths, life-threatening incidents, falls, insomnia, nausea and fatigue. In more than 1,000 reports, patients continued to experience hallucinations while on Nuplazid.

In November, an analysis released by a nonprofit health care organization, the Institute for Safe Medication Practices, warned that 244 deaths had been reported to the FDA between the drug's launch and March 2017. The organization also noted that hundreds of reports suggested the drug was "not providing the expected benefit" or potentially worsening the condition.

......

After analyzing the adverse event data for Nuplazid, the Institute for Safe Medication Practices concluded that this batch of reports "reinforces the concerns of those who warned that (Nuplazid) might do more harm than good." Thomas Moore, senior scientist for drug safety and policy for the nonprofit, said the deaths are an "important warning signal" and warrant further review by the FDA -- and possible action, depending on what the review finds.

Since the institute released its analysis, FDA data shows that the number of reported deaths has risen to more than 700. As of last June, Nuplazid was the only medication listed as "suspect" in at least 500 of the death reports.

This is almost unheard of to have this many deaths reported...you have to take it seriously.

DIANA ZUCKERMAN, PRESIDENT OF THE NATIONAL CENTER FOR HEALTH RESEARCH


Physicians, medical researchers and other experts told CNN that they worried that the drug had been approved too quickly, based on too little evidence that it was safe or effective. And given these mounting reports of deaths, they say that more needs to be done to assess Nuplazid's true risks.

"This is almost unheard of, to have this many deaths reported," said Diana Zuckerman, founder and president of the nonprofit thinktank the National Center for Health Research, adding that because reports are voluntary, potential problems may be underreported. "You just don't see this with most new drugs -- you don't see all these reports -- so you have to take it seriously."

.......


In an interview this week, FDA commissioner Scott Gottlieb was asked by CNN's Dr. Sanjay Gupta about his thoughts on drugs that receive expedited reviews and then prompt concerns about safety once they become available, like Nuplazid. While Gottlieb didn't want to comment on a specific product, he said he is "familiar with the circumstances" and that it's very important for the agency to make sure it is "appropriately balancing" safety with medical need. He said this is a flexible standard, however, and there may be more tolerance for risk in situations where there is a significant need and patients don't have an alternative.


"You've seen us take regulatory action recently in the post-market setting to limit the use of drugs when new safety concerns became known," he said.

The FDA told CNN it will continue to monitor the adverse event reports and review the drug's safety. It added that Nuplazid's "complex safety profile," recognized at the time of its approval, resulted in a requirement that the medication carry a number of warnings on its label so that doctors could analyze potential risks and benefits before prescribing the drug.

The cases reported so far, according to the FDA, typically involved elderly patients with advanced-stage Parkinson's disease who suffer from numerous medical conditions and often take other medications that can increase the risk of death.


"Based on these data, the FDA has, at this time, not identified a specific safety issue that is not already adequately described in the product labeling," the agency said in a statement.
The FDA has required antipsychotics to carry its most severe "black box" warning for the treatment of elderly dementia patients, after studies found that the medications increase the risk of death in this population. Between 50% and 80% of Parkinson's patients experience dementia as the disease worsens, according to the Alzheimer's Association. Because Nuplazid is a new kind of antipsychotic that targets a different receptor in the brain, its maker claims it comes with fewer toxic side effects. Even so, Nuplazid also carries a black box warning.

Geriatric psychiatrist and former FDA medical officer Susan Molchan said that the number of deaths is alarming and questioned whether patients and their families are aware of the risks associated with the drug.
To determine the true risks of Nuplazid, the researchers interviewed by CNN said, the FDA needs to require further scientific studies -- and not just rely on the reports, which are challenging to interpret and are not systematically collected. They also worried that, because the drug was already approved, these studies and any action by the FDA could take years.


Hundreds of adverse event reports

A CNN review of several hundred adverse event reports shows that the detail provided for each case varies widely and that thorough investigations are rarely conducted -- making it difficult to determine whether Nuplazid might have been involved in the deaths of already sick and elderly patients.

In these reports, the physicians who prescribed the drug sometimes suggest that their patients likely died from complications from Parkinson's rather than because of Nuplazid. In other cases, it's unclear when exactly the patient started or stopped taking the medication. And in yet others, family members and sometimes doctors are convinced the drug contributed to the deaths.


This is exactly what I thought I was going to happen.

DR. PAUL ANDREASON, WHO LED THE FDA MEDICAL REVIEW OF NUPLAZID


'''''

In another report, an 89-year-old man was taken off the drug after experiencing a significant decline. His doctor blamed Nuplazid for his deteriorating condition. The patient died weeks later. In a third report, a woman flagged her husband's death to the FDA after he was taken to the hospital due to dehydration. After he passed away, she said, she was told by "someone at the hospital" that the death was connected to his use of Nuplazid.

Acadia said it analyzed these reports and concluded that there "is nothing to suggest a causal relationship to Nuplazid." Acadia calculated a mortality rate for Nuplazid, which it said was lower than what you'd see in the general population of Parkinson's disease psychosis patients covered by Medicare. It calculated this using deaths reported to the FDA and what it considered a conservative estimate of patients on the drug, along with Medicare claims data. However, multiple experts interviewed by CNN said that this is an unreliable calculation since it is comparing apples to oranges.

....

Widening the patient pool
In the weeks after the Institute for Safe Medication Practices issued its report on the deaths, Acadia's stock price dropped by more than 20%. While many large investors remain bullish about the stock, some investment analysts have made public records requests to the FDA for the death reports.

....

Currently, Nuplazid can cost nearly $100 a day, according to wholesale pricing data from First Databank. That can add up to more than $30,000 a year for a single patient, though the amount a patient actually pays depends on factors including individual insurance coverage.

Acadia expects sales of Nuplazid to at least double this year.


The company, meanwhile, is forging ahead with clinical trials in an attempt to get the medication approved for use in a larger patient population: patients who have dementia-related psychosis. In October, the FDA granted its coveted breakthrough designation for this potential use as well, meaning it will also undergo a speedier review process.
While a doctor can legally prescribe a drug for any reason, insurance companies may not approve it for uses that are not FDA-approved. So FDA approval to treat dementia patients would likely result in Nuplazid being prescribed to a much wider population, concerned medical experts told CNN.

"You would certainly hope they don't approve it for anything else," said Zuckerman of the National Center for Health Research, based on the current research and FDA adverse event reports. "If they're going to approve it for another group of patients that is much, much larger -- that would be unconscionable.

.......



Roughly two years have passed since that FDA meeting, where family members and caregivers -- some of whom traveled there on Acadia's dime -- gathered with medical experts to debate the merits and potential risks of Nuplazid.

Andreason, the physician who led the FDA's medical review of Nuplazid, no longer works for the agency.

He said that while he stands by the warnings he made at the time, he understands that other antipsychotics used to treat Parkinson's patients also come with an increased risk of death and that, when patients have a debilitating disease like Parkinson's, physicians and caregivers may choose a medication that improves quality of life even if it could also shorten life expectancy.

He said that he was not surprised to hear about the reports of death.
Knowing what I know now -- that it didn't work at all -- I wouldn't have gotten my hopes up.

"This is exactly what I thought was going to happen," he said. "We were going to get a burst of reports of serious adverse events and deaths."
Dr. Stephanie Fox-Rawlings, a senior fellow at the National Center for Health Research who spoke against the drug's approval at the FDA committee meeting, recently told CNN she understands how desperate families in these situations are, but she does not think Nuplazid is the answer based on her review of Acadia's public research. She and Zuckerman said that, after previous studies didn't show it was effective, the drugmaker changed the way the medication's ability to improve psychosis was measured, which resulted in a positive outcome. Acadia said its studies have had different objectives and all of them have used "consistent, appropriate, and validated assessment methodology."

......

CNN reached two of the three family members who petitioned for Nuplazid's approval at the meeting, despite having had no experience with the drug or its clinical trials, to ask whether they tried the medication once it hit the market.

One of these was Elaine Casavant. Despite the "staggering cost" of the medication, she said, she was quick to get her husband on it. But after three months, he showed no improvement and they stopped the medication. She has heard success stories, however, and remains optimistic that the drug could be helping certain people.
