Pregabalin (Pfizer).

Abstract

Pfizer is developing pregabalin, a follow-up compound to its GABA agonist gabapentin, for the potential treatment of several central nervous system (CNS) disorders including epilepsy, neuropathic pain, anxiety and social phobia [286425]. By December 2000, Pfizer anticipated filing an NDA for pregabalin for seven major indications (beginning with neuropathic pain and add-on epilepsy), with the FDA by the end of 2001. Filings for generalized anxiety disorder (GAD), social anxiety disorder and fibromyalgia are expected to take place in 2002, and filings for epilepsy monotherapy and panic disorders are expected to take place in early- and late-2003, respectively [336918], [393182], [399956]. By January 2001, pregabalin was in phase II development in Japan for the potential treatment of neuropathic pain, with an anticipated approval date of 2005 [394827]. However, following analysis by the FDA of a mouse study that showed incidence of a specific tumor type, Pfizer announced in February 2001, that it is restricting the use of pregablin in some clinical patients [398726] and it has frozen trials for neuropathic pain [398785]. In April 2001, Morgan Stanley Dean Witter predicted potential sales of $350 million in 2002, rising to $1750 million in 2006, with peak sales in excess of $2000 million [406923].

Human nuclear transcription factor gene CREM: genomic organization, mutation screening, and association analysis in panic disorder.

Panic disorder is an anxiety disorder with an estimated heritability of 48%. Variation in the gene of the nuclear transcription factor "cAMP-responsive element modulator" (CREM) might contribute to its pathogenesis. CREM knock-out mice exhibit significantly less anxiety behavior than wild-type mice and the alternative CREM gene product "inducible cAMP early repressor" (ICER) plays a pivotal role in the hypothalamo-pituitary-adrenal (HPA) axis, which is disturbed in panic disorder. We characterized the genomic organization of the human CREM gene and performed a systematic mutation screening by means of single stranded conformational analysis (SSCA) in a sample of 40 German patients with panic disorder (DSM-III-R). Four novel single nucleotide polymorphisms in CREM promoters P 1 and P 4, one trinucleotide (ATT)-repeat polymorphism in CREM promoter P 2-generating the ICER isoform-and a rare amino acid substitution in CREM exon glut 2 were identified. Association analysis in an extended sample of German patients (n = 88) revealed a significant excess of the shorter CREM P 2 promoter eight-repeat trinucleotide allele and of genotypes containing the eight-repeat trinucleotide allele in panic disorder (P = 0.02), in particular in panic disorder without agoraphobia (P = 0.001). A replication study in independent Italian (n = 76) and Spanish (n = 62) samples, however, failed to confirm this observation. This suggests that the CREM P 2 promoter trinucleotide polymorphism is not a major susceptibility factor in the pathogenesis of panic disorder. Functional analysis of the observed CREM P 2 promoter polymorphism as well as studies in independent panic disorder samples are necessary.

Review of the long-term effectiveness of cognitive behavioral therapy compared to medications in panic disorder.

Panic disorder is a recurrent and disabling illness. It is believed that Cognitive Behavioral Therapy (CBT) has a long-term protective effect for this disorder. This would offer CBT considerable advantage over medication management of panic disorder, as patients often relapse when they are tapered off their medications. This is a review of the literature about the long-term effectiveness of CBT. We searched for follow-up studies of panic disorder using CBT. Of the 78 citations produced in the initial search, most had major methodological flaws, including ignoring losses to follow-up, not accounting for interval treatment, and unclear reporting. Three papers met strict methodological criteria, and two of these demonstrated a modest protective effect of CBT in panic disorder patients. We make recommendations for well-designed studies involving comparisons of medications and cognitive behavior therapy.

Agoraphobia↗

[First onset of panic disorder and agoraphobia induced by a series of inappropriate shocks of an implanted cardioverter/defibrillator].

We report on a 61-year-old patient with an implanted defibrillator due to malignant arrhythmia after myocardial infarction. After several years of appropriate function, the patient suffered a cluster of 16 shocks due to a defect in the defibrillator. Soon the patient developed a panic disorder with agoraphobia which was successfully treated with cognitive-behavioral therapy. Possible cognitive-behavioral mechanisms of panic disorder and special issues of behavioral therapy of patients with serious organic diseases are discussed.
