Broken Promises with Abilify

Based upon sales data for the world’s 15 top selling drugs, Abilify was ranked fourth, with $9.3 billion of sales in 2014. Reflect for a moment what this means; an antipsychotic drug had greater worldwide sales than Nexium (for acid reflux) and Crestor (for high cholesterol). While it is an approved medication in the US for bipolar 1 and schizophrenia, it is likely these sales figures reflect it use as an adjunct medication for major depression. Oh, and along with other antipsychotics, it is used off label to treat several other behavioral disorders such as Tourette’s and irritability associated with autism. This popularity is despite the reality that antipsychotics have a high incidence of negative side effects—greater than antidepressants and anti-anxiety medications.

The problems with antipsychotics have been known for a few years. As far back as 2010, Robert Field wrote: “Antipsychotic Medications Are Spelling Legal Trouble for Drugmakers” for the journal Pharmacy and Therapeutics. In 2007, Bristol-Myers Squibb paid $515 million to settle charges of illegally marketing Abilify for children and the elderly, “In contravention of FDA-approved labeling.” But that hasn’t been the end of legal troubles regarding Abilify. On May 3, 2016, the FDA published a safety announcement warning that Abilify (aripiprazole) can trigger impulse-control problems such as “compulsive or uncontrollable urges to gamble, binge eat, shop, and have sex.” These urges reportedly stop when the drug is discontinued or the dose reduced.

These compulsive behaviors can affect anyone who is taking the medicine. As a result, we are adding new warnings about all of these compulsive behaviors to the drug labels and the patient Medication Guides for all aripiprazole products.

The mechanism of action for Abilify is not clearly understood, but researchers think it over-stimulates dopamine 3 (D3) reward receptors, which are mainly located in the limbic system. This in turn triggers the compulsive behaviors. Gaboriau et al. reviewed case reports in Addictive Behaviors and indicated that pathological gambling (PG) appeared as quickly as a few days after Abilify was started; sometimes after an increase in dosage with 7 of the 8 case reports. PG then decreased after Abilify treatment was stopped or decreased; again sometimes as soon as a few days afterwards.

Limitations on the Gaboriau et al. findings included that most of the patients were already gambling before starting with Abilify. Several patients also had a history of substance use disorders. However, the authors noted that the same D3 receptor was implicated in another study by J. E. Ahiskog of the dopamine agonist medications, pramipexole and ropinirole, which are commonly used to treat Parkinson’s disease.

This hyperstimulation would apparently be particularly enhanced in cases of a previous treatment by antipsychotics acting as a dopaminergic receptors antagonist, owing to the up-regulation and the dopaminergic receptor hypersensitivity processes. The partial agonist action of aripiprazole then causes stronger effects. Moreover, the intrinsic dopamine pharmacodynamic activity of aripiprazole imparts it less action agonist than a complete agonist, which could explain why the occurrence of PG is sometimes late or due to dosage increase.

The above concern with Abilify was also supported by the findings of a study by Moore, Glenmullen and Mattison reported in JAMA Internal Medicine. Adverse drug event reports received by the FDA from 2003 to 2012 were reviewed for the six dopamine receptor agonist drugs marketed in the U.S. The review identified 1580 reports of impulse control disorder events, including pathological gambling, hypersexuality, compulsive shopping and others. They also detected weaker signals for antidepressants and antipsychotics.

The Daily Beast reported on a massive tort lawsuit being filed against Otuska and Bristol-Myers Squibb charging that Abilify created a compulsion for sex and gambling. Moreover, the suit claims the drug makers knew of the serious side effects because of required changes in Canadian and European warning labels, but waited for years to warn U.S. consumers. Thomas Moore of the Institute for Safe Medication Practices explained the drug triggers an urge to gamble constantly, sometimes with people with no prior interest. “It might be people starting to spend $300 a week on lottery tickets, and in other cases people will gamble away tens of thousands of dollars.” Moore went on to say:

We live in a society whose rules and laws assume people are responsible for their actions, including running up a large gambling debt. . . But we have scientific evidence that sometimes a drug can trigger a pathological urge to gamble so severe it can ruin someone’s life.

A woman who began using Abilify to aid in treating her PTSD developed a compulsive gambling problem. She used up her unemployment checks, pawned her husband’s automotive tools, and lied about needing money for baby formula. “Nothing was off-limits when it came to getting the money I needed to keep up the ruse.” She’d stuff her bed at night in order to fool her husband into thinking she was asleep when she was actually at the casino playing the slot machines.

Another woman developed hypersexuality. She started with online chatting with men. She became obsessed with sexual fantasies and took sexualized pictures of herself and sent them to select ‘friends.’ “I just couldn’t stop with the pictures and fantasies.” She also went on shopping sprees. Then her husband caught her. “The drug has destroyed my life, my reputation, and the lives of those I love.”

The website RxISK has multiple reports on adverse events with Abilify. “Abilify from the Inside Out” described bouts of akathisia (a state of agitation, distress, and restlessness), unusual aggression or anger, first time episodes of psychosis, suicidality, at least three confirmed suicides, movement disorders such as tremors, and (of course) compulsive gambling. The author said the reports were hard for him to read. Since most of the patients were on several meds, some patients couldn’t be sure that Abilify alone caused the problem. Even stopping Abilify was related to adverse drug events.

The above noted 2007 lawsuit, where Bristol-Myers Squibb paid $525 million to settle charges of illegal marketing, unveiled some of the marketing records for Abilify. Remember, one of the concerns was that it was illegally marketed for use with the elderly. The sales reps for Abilify would invite nursing home staff to picture a new resident, hunched in their chair, staring off into space because of ‘depression.’ “’Who wants to see that when they come to visit Mom on a Saturday?’ the reps would ask. ‘Wouldn’t we like to see her up and about, looking lively?’” The sale pitch worked. One woman wrote the following to RxISK:

I have seen many commercials about how drugs like Abilify can perk people right up. . . So I was not only disappointed and frightened by the results, but felt once again tricked and exploited by the big promises that drug companies make but never seem to keep.

I wish the above concerns weren’t true. But I’ve known individuals whose experiences on Abilify are consistent with the above discussion of its adverse effects. Sadly, even when sanctions are in the millions of dollars, the profits are higher. And it seems the cards are stacked against pharmaceutical companies being held accountable financially. So consumers have to fight against this by refusing to use Abilify and telling others what you have read here.

Abilify in Denial

Modern Healthcare reported that Proteus Digital Health, a California company, is partnering with Otusuka Pharmaceuticals to approve an Abilify “smart pill.” When a medication embedded with a sensor reaches the stomach, it sends a signal to a wearable sensor patch. The patch records and time-stamps the information and other information such as rest and activity patterns. Then the information can be relayed to patients on their phones or other Bluetooth-enabled devices; or it can be forwarded to physicians or caregivers.

It was just in July of 2015 that Proteus announced that the FDA had expanded the Indications for Use statement for its Ingestible Sensor technology to be used as an aid in measuring medication adherence. At this point in time, it seems to be the only device with an FDA-sanctioned claim for measuring medication compliance. Proteus and Modern Healthcare pointed to findings from a 2014 article in Risk Management and Healthcare Policy that estimated avoidable healthcare costs from poor medication adherence as between $100 to $300 billion annually in the U.S. That represents 3% to 10% of total U.S. healthcare costs.

Dr. George Savage, the co-founder and chief medical officer of Proteus, said the company hopes to give patients feedback on their adherence so they can improve their health and avoid adverse medication events. Dr. William Carson, the president and CEO of Otsuka Pharmaceuticals said: “We believe this new digital medicine could revolutionize the way adherence is measured and fulfill a serious unmet medical need in this population.” They expect a response from the FDA by April of 2016.

There is reportedly a widespread problem of with non-adherence to taking medications as prescribed, especially with individuals with mental illness. So the FDA suggested to Proteus that the need for an ingestible sensor was most needed by mental health patients. It seems to have been rushed through the approval process, with about nine months from the FDA approved expansion of the Indications for Use statement for Proteus’s Ingestible Sensor to the expected response by the FDA approving the Abiliy “smart pill.” So there are two questions to ask about this. Why the rush? Why is the greatest need for a smart pill with antipsychotics like Abilify?

Abilify went off of patent in October of 2014 and was made available as a generic in April of 2015. The Abilify smart pill would probably be a new molecular entity (NME) and thus eligible for a new patent. While aripiprazole (Abilify) will be available as a generic, only Otsuka and Proteus will be able to sell the smart pill version. Otsuka and its former distribution partner, Bristol-Myers Squibb, grossed $5.5 billion in Abilify sales for 2014.

The pressing need for a smart pill with psychiatric medications to help counter non-adherence issues is because there are serious, and sometimes debilitating side effects from taking them. Here is a link to an advertisement for Abilify as an add-on medication with antidepressants to treat depression. Most of the audio in the 90-second commercial is describing the potential side effects.

The side effects from antipsychotics can include: weight gain, diabetes, pancreatitis, gynecomastia (abnormal breast tissue growth), hypotension, akathesia (a feeling of inner restlessness), cardiac arrhythmias, seizures, sexual dysfuntion, tardive dyskinesia, anticholinergic effects (constipation, dry mouth, blurred vision, urinary retention and at times cognitive impairment). Read more about these and other side effects at: “Side Effect of Atypical Antipsychotics: A Brief Overview”;  “Antipsychotic Drugs, Their Adverse Effects”; “Adverse Effects of Antipsychotic Medications”; and “An Overview of Side Effects Caused by Typical Antipsychotics.”

The website RxISK described some of the reports and first-hand accounts about individuals who had used Abilify in: “Abilify From the Inside Out.” Out of 34 who had used Abilify, only five had taken it for a “psychotic” diagnosis. Fourteen were taking it for depression. Six used it for bipolar disorder; three for other diagnoses; two for “stress”; and three for unknown reasons. Fifteen individuals were taking Abilify in conjunction with antidepressants.

Most patients were on more than one medication, so they could not be sure that if Abilify alone caused these adverse effects. Nevertheless, there were three confirmed suicides and several episodes of severe emotional stress or physical misery. Eight people reported akathisia and six reported unusual anger or aggression. Two of the aggression episodes were violent physical attacks on family members. One woman assaulted her husband when she had “bizarre and frightening thoughts.”

At the other extreme, 14 people reported over-sedation and cognitive slowing, with memory, concentration and word-finding problems.  About half felt a profound emotional numbing, an inability to feel pleasure or care about anything. One man regretted this state, but felt it was better than his prior severe depression.  For the rest, however, it brought new or worse depression.  Three felt trapped at home by “total lack of interest in life” along with anxious depression; loss of the ability to pursue, or even care about, formerly cherished goals was painful for others.  Most reported suicidal thoughts of varying intensity.

Three people had tremors, but of these cases cleared up when they stopped the drug. Four others had tardive dyskinesia. Their symptoms started after using Abilify for at least a year; and they continued despite stopping the drug. “They found their condition painful, debilitating, disfiguring and socially isolating.” Four men reported sexual dysfunction. One man had a gambling problem that began two months after starting Abilify. “Eight people had their worst problems on stopping Abilify.”

Johanna Ryan, who wrote the article on RxISK, said that most antidepressants are metabolized in the liver by the same enzymes that process Abilify. So the resulting “traffic jam” will effectively raise the level of Abilify in your blood. Some SSRIs have also a stronger effect than others on this issue. “Your actual Abilify levels might be 150% to 300% of your official dose.” Side effects such as agitation, anxiety, insomnia and nervousness commonly occur with antidepressants and can increase your chances of akathisia with Abilify.

In other words, the “little baby dose” was an illusion.  Even 2 mg was bigger than it seemed – and doses over 5 mg could put you on a par with patients taking Abilify for psychosis.  (Those patients may be taking excessive doses as well: Two patients with psychotic symptoms in the RxISK group found they did better on half the dose their doctor initially prescribed.)

In “Dodging Abilify” on RxISK, Johanna Ryan related how a psychiatrist had tried to convince her once to try Abilify for her depression.  He told her “these drugs” (referring to Abilify) weren’t really antipsychotics since they were used to treat several kinds of things. “’Oh, come on,’ he coaxed.  ‘We’re talking about little baby doses here, just a fraction what they give people for schizophrenia.’”  Like other antipsychotics, it blocks certain dopamine receptors. Unlike them, it is a “partial agonist,” meaning it activates others.

Now let’s go back to the cute Abilify commercials. This one includes a woman and her umbrella. Listen to see if Abilify is ever referred to as an antipsychotic or neuroleptic. As a matter of fact, it wasn’t. The same is true for the link to the commercial above. Admittedly, these commercials were pushing Abilify as an add-on to antidepressants. But now download the FDA Medication Guide for Abilify, and search through it. You won’t find the word “antipsychotic.” The word “neuroleptic” appears once within the listing of a side effect: neuroleptic malignant syndrome. Abilify is described and presented as an “antidepressant medicine” throughout the medication guide. There were other antipsychotics that seemed to also minimize using these two words (neuroleptic and antipsychotic) in referring to their drug, but not to the same extent as noted for Abilify. My thought is Otusuka decided that referring to Abilify as an antipsychotic or neuroleptic was bad for business.

So Abilify is a neuroleptic that apparently wants to be known as an antidepressant and absolutely HATES to be referred to as an antipsychotic. Yet it has the same kinds of adverse side effects as other neuroleptics. (If it walks like a duck and talks like a duck …) And of all the current antipsychotics on the market, Proteus partnered with Otsuka first to create an Abilify smart pill to facilitate medication compliance with its drug. To borrow a phrase from addiction recovery, it sounds like Abilify is in denial about being an antipsychotic.
