BioLineRx Presents Data From Successful Phase I Trial for BL-1020 in Schizophrenia at American Psychiatric Association Conference.Company Expects to Initiate Phase II Trial in June 2007 SAN DIEGO -- BioLineRx Ltd. (TASE:BLRX), Israel's leading drug development company, reported today data from its Phase I trial of BL-1020, the first GABA GABA ?. GABA abbr. gamma-aminobutyric acid GABA (gamma-aminobutyric acid) A neurotransmitter that slows down the activity of nerve cells in the brain. enhanced antipsychotic clinical candidate for the treatment of schizophrenia The concept of a cure as such in the treatment of schizophrenia remains controversial, as there is no consensus on the definition of "treatment" in the case of schizophrenia, although some criteria for the remission of symptoms have recently been suggested. . The trial demonstrated that the compound was well tolerated and demonstrated biochemical evidence of dopamine blockade which is indicative of efficacy. BioLineRx presented the data in a poster (Abstract 235 XX) at the 2007 American Psychiatric Association The American Psychiatric Association (APA) is the main professional organization of psychiatrists and trainee psychiatrists in the United States, and the most influential world-wide. Its some 148,000 members are mainly American but some are international. (APA (All Points Addressable) Refers to an array (bitmapped screen, matrix, etc.) in which all bits or cells can be individually manipulated. APA - Application Portability Architecture ) Annual Meeting, which is being held May 19-24 in San-Diego, CA. A Phase II clinical trial Noun 1. phase II clinical trial - a clinical trial on more persons than in phase I; intended to evaluate the efficacy of a treatment for the condition it is intended to treat; possible side effects are monitored phase II for BL-1020 to determine the maximum tolerated dose in schizophrenic patients is expected to begin in the end of June, 2007. "We are pleased to be presenting these promising results for BL-1020 at the APA Annual Meeting and look forward to the imminent initiation of the Phase II trial for this compound," commented Morris C. Laster, M.D., chief executive officer of BioLineRx. The results of this trial were as follows: 1. BL-1020 demonstrated dopamine blockade by dose dependant elevation in serum prolactin prolactin /pro·lac·tin/ (-lak´tin) a hormone of the anterior pituitary that stimulates and sustains lactation in postpartum mammals, and shows luteotropic activity in certain mammals. pro·lac·tin n. levels which serves as a surrogate marker for dopamine antagonism. Dopamine hyperactivity is implicated in schizophrenia, and is the mechanism of action for various antipsychotic drugs. 2. In this trial BL-1020 appeared to be protective against extrapyramidal symptoms, a severe side effect of many antipsychotic medications. BL-1020 was extremely well tolerated in that no ECG psychiatric or neurological abnormalities were seen at any of the doses tested. About the BL-1020 Phase I Clinical Trial Noun 1. phase I clinical trial - a clinical trial on a few persons to determine the safety of a new drug or invasive medical device; for drugs, dosage or toxicity limits should be obtained phase I The Phase 1 trial of BL-1020 was a randomized ran·dom·ize tr.v. ran·dom·ized, ran·dom·iz·ing, ran·dom·iz·es To make random in arrangement, especially in order to control the variables in an experiment. , double blind, placebo-controlled, dose-escalation, single center study in healthy adult males (ages 21-45). The primary objective was to evaluate the safety and tolerability of escalating doses of BL-1020. The secondary objectives were to determine the pharmacokinetics of BL-1020, and to assess its ability to block activity of the neurotransmitter dopamine, implicated in schizophrenia. 48 volunteers participated in the Phase I trial. They were randomized and enrolled into 6 dose cohorts at a ratio of 6:2 (BL-1020: placebo). In each cohort, patients received a single dose or matching placebo (4, 8, 16, 24, 32 or 40 mg). The results demonstrate that BL-1020 was well tolerated following administration of a single dose up to 40 mg, with no adverse drug related effects on ECG parameters, clinical lab data and neurological assessments. About BL-1020 BL-1020 is an orally available GABA enhanced antipsychotic clinical candidate for the treatment of schizophrenia. Data from preclinical and phase I studies demonstrated that the compound may retain the efficacy of currently available typical and atypical antipsychotic drugs Antipsychotic Drugs, Atypical Definition The atypical antipsychotic agents, sometimes called the "novel" antipsychotic agents are a group of drugs which are different chemically from the older drugs used to treat psychosis. while achieving a much higher safety profile as evidenced by a lack of metabolic or extrapyramidal extrapyramidal /ex·tra·py·ram·i·dal/ (-pi-ram´i-d'l) outside the pyramidal tracts; see under system. ex·tra·py·ram·i·dal adj. side effects. BL-1020 is designed to simultaneously target the dopamine hyperactivity and GABA hypoactivity of schizophrenia. Exogenously administered GABA is ineffective as a therapeutic agent due to its inability to cross the blood brain barrier. Pharmacokinetic studies demonstrate that BL-1020 provides effective transport of GABA into the brain, overcoming this challenge. Receptor binding studies indicate that BL-1020 has a high affinity to dopamine and specific GABA-A agonist activity. This unique clinical profile may explain the reduction in side effects observed in animals and may contribute to improving cognitive function in schizophrenia.
