Campral (Acamprosate Calcium) - Summary



CAMPRAL® (acamprosate calcium) Delayed-Release Tablets

CAMPRAL ® (acamprosate calcium) is supplied in an enteric-coated tablet for oral administration. Acamprosate calcium is a synthetic compound with a chemical structure similar to that of the endogenous amino acid homotaurine, which is a structural analogue of the amino acid neurotransmitter (gamma)-aminobutyric acid and the amino acid neuromodulator taurine.

CAMPRAL is indicated for the maintenance of abstinence from alcohol in patients with alcohol dependence who are abstinent at treatment initiation. Treatment with CAMPRAL should be part of a comprehensive management program that includes psychosocial support.

The efficacy of CAMPRAL in promoting abstinence has not been demonstrated in subjects who have not undergone detoxification and not achieved alcohol abstinence prior to beginning CAMPRAL treatment. The efficacy of CAMPRAL in promoting abstinence from alcohol in polysubstance abusers has not been adequately assessed.

The effects of combined acamprosate and integrative behaviour therapy in the outpatient treatment of alcohol dependence: a randomized controlled trial. [2011.11.01]
AIMS: The aim of this randomized, controlled, multisite trial was to evaluate the efficacy of combined treatment with integrative behaviour therapy (IBT) and acamprosate on drinking behaviour in detoxified alcohol-dependent patients... CONCLUSION: The results suggest that the combination of acamprosate and IBT is not more effective than treatment with either IBT or acamprosate alone. However, the two acamprosate conditions differed in success rate by about 10%, which might constitute a clinically relevant though statistically non-significant effect.

Involvement of the atrial natriuretic peptide transcription factor GATA4 in alcohol dependence, relapse risk and treatment response to acamprosate. [2011.10]
In alcoholism, both relapse to alcohol drinking and treatment response are suggested to be genetically modulated. This study set out to determine whether the top 15 single nucleotide polymorphisms (SNPs) of a recent genome-wide association (GWA) and follow-up study of alcohol dependence are associated with relapse behavior and pharmacological treatment response in 374 alcohol-dependent subjects who underwent a randomized, double-blind, placebo-controlled trial with acamprosate, naltrexone or placebo...

Impact of Depressive Symptoms on Future Alcohol Use in Patients with Co-Occurring Bipolar Disorder and Alcohol Dependence: A Prospective Analysis in an 8-Week Randomized Controlled Trial of Acamprosate. [2011.09.20]
Background: Bipolar disorders and alcohol use disorders commonly co-occur, yet little is known about the proximal impact of bipolar symptoms on alcohol use in patients with this comorbidity. The present study examined the impact of depressive symptoms and alcohol craving on proximal alcohol use in patients with co-occurring bipolar disorder and alcohol dependence...

Clinical Trials Related to Campral (Acamprosate)

Safety of Acamprosate for Alcohol Dependence in the Elderly: An Open-Label Study (SAFADIE) [Recruiting]
Alcohol abuse and dependence are very prevalent and result in significant morbidity, mortality and cost to society (Harwood 2000). Pharmacotherapies to assist with alcohol dependence consist of disulfiram, naltrexone and acamprosate. Of these, acamprosate is unique in that it is not metabolized by the liver, but rather completely excreted renally. In contrast, naltrexone is metabolized by the CYP450 system of the liver and less than 2% is excreted unchanged and can cause liver damage (PDR 2005). Multiple cases of hepatitis, including both cholestatic and fulminant hepatitis, as well as hepatic failure resulting in transplantation or death, have been reported with administration of disulfiram (PDR 2005). The incidence of liver disease among alcoholics is high and increases with age and years of drinking and this may preclude the use of antabuse or naltrexone to help alcohol dependent patients with liver disease or that are elderly . Thus acamprosate has a unique safety profile that would make it ideally suited for treating alcohol dependence in the elderly, even in the presence of hepatic impairment. The current study is to evaluate the safety profile of acamprosate in elderly patients with alcohol dependence.

Acamprosate, calcium acetyl homotaurinate, has been approved in most European countries and the U. S. for the maintenance of abstinence in recently detoxified alcoholics. The mechanism

of action involves primarily the restoration of a normal N-methyl- D - aspartate (NMDA)

receptor tone in glutamatergic systems (Rammes et al 2001). Several trials of acamprosate confirm its efficacy in the maintenance of abstinence in alcohol dependence (Lesch et al. 2001; Slattery et al. 2003; Mann et al. 2004; Verheul et al. 2004). It also reduces the severity of relapse in alcoholics in abstinence based treatment programs (Chick et al. 2003). There is limited data on the safety of acamprosate in the elderly (PDR 2005).

For the purposes of this study, elderly will be defined as 60 years or older.

STUDY OBJECTIVE: To determine the short-term safety of Acamprosate in the treatment of alcohol dependence in the elderly.

Acamprosate: Genes Associated With Response [Recruiting]
In 2004, acamprosate was approved in the U. S. for abstinence maintenance, by decreasing craving, in alcoholic patients who have undergone detoxification. while a new anti-craving drug was encouraging, only 36. 1% of the subjects treated with acamprosate remained abstinent for 6 months. Having the ability to identify treatment responsive individuals would have a major impact on the use of acamprosate.

Biomarker Study of Acamprosate in Schizophrenia [Recruiting]
NMDA receptors are brain receptors that are stimulated by glutamate. Poorly functioning NMDA receptors are thought to be involved in the pathology of schizophrenia. This hypothesis is based on the observation that PCP, which blocks the NMDA receptor, produces symptoms and cognitive impairments similar to schizophrenia. Efforts to enhance the function of the NMDA receptor with glycine and D-cycloserine have met with limited success. An alternative approach would be to use the drug acamprosate.

Acamprosate, FDA-approved for maintenance of sobriety after detoxification from alcohol, seems to act through modulation of the NMDA receptor. In the lab, acamprosate has been noted to act as an antagonist when the NMDA receptors are maximally stimulated but as an agonist when NMDA receptor stimulation is minimal. This "smart drug" action makes acamprosate appealing for use in schizophrenia. If acamprosate works as a smart drug in patients, then we would predict that it would enhance the function of NMDA receptors in schizophrenia and improve cognition and the symptoms of the illness. Additionally, acamprosate seems to modulate the NMDA receptor in novel ways distinct from glycine and D-cycloserine.

We will also see if the response to acamprosate differs based on whether participants do or do not have a past history of alcohol use disorders.

Pilot Trial of Acamprosate for the Treatment of Cocaine Dependence [Active, not recruiting]

Acamprosate in Youth With Fragile X Syndrome [Recruiting]
Fragile X syndrome (FXS) is the most common inherited form of developmental disability. FXS is inherited from the carrier parent, most often the mothers. FXS is associated with severe interfering behavioral symptoms which include anxiety related symptoms, attention deficit hyperactivity, and aggressive behaviors. Approximately 25-33% of individuals with FXS also meet criteria for autistic disorder. The hypothesis of this study is that treatment with acamprosate will reduce inattention/hyperactivity, language impairment, irritability, social deficits, and cognitive delay in youth with FXS. The purpose of this study is to investigate the effectiveness and tolerability of acamprosate in youth with Fragile X Syndrome and to assess the potential psychophysiological differences between FXS and autism spectrum disorders.
