Drug Name: Bitopertin (Treatment for Schizophrenia)
Positive phase II proof-of-concept data with RG1678 in patients with predominantly negative symptoms of schizophrenia were presented at an international medical meeting . Based on these promising results, a global phase III program was initiated including a total of six studies investigating RG1678 in combination with standard of care antipsychotic drugs in patients with either negative symptoms or residual positive symptoms of schizophrenia. Running the studies for both indications in parallel allowed a better understanding of the effect of RG1678 on a broad spectrum of symptoms and its value in the management of patients at different phases of their disease.
RG1678( Bitopertin) is a glycine transporter type 1 (GlyT1) inhibitor that increases levels of the neurotransmitter glycine by inhibiting its reuptake from the synaptic cleft. Glycine acts as a required co-agonist along with glutamate at N-methyl-D-aspartate receptors. Dysfunction of NMDA receptors may play a key role in the pathogenesis of schizophrenia and modulation of glutamatergic signalling via increased concentrations of glycine in the synaptic cleft may help potentiate NMDA receptor function and improve the symptoms of schizophrenia. Bitopertin is administered orally at 10 mg or
In a Phase II proof-of-concept study patients on RG1678 experienced a significant improvement in the change of the Negative Symptom Factor Score from baseline within 8 weeks. The first patient was randomized into the phase III program in November 2010.Phase III trials are currently underway and expected to be completed by 2015.

    Background: We aimed to explore relations between symptomatic remission and functionality evaluation in schizophrenia patients treated with paliperidone extended-release (ER), as seen in a normal day-to-day practice, using flexible dosing regimens of paliperidone ER. We explored symptomatic remission rate in patients treated with flexibly dosed paliperidone ER by 8 items of Positive and Negative Syndrome Scale (PANSS) and change of Personal and Social Performance (PSP) scale. Method: This was a 12-week multicenter, open-label, prospective clinical study conducted in in-patient and outpatient populations. Flexible dosing in the range 3-12 mg/day was used throughout the study. All subjects attended clinic visits on weeks 0, 4, 8, and 12 as usual clinical practice for the 12-week observation period. Data were summarized with respect to demographic and baseline characteristics, efficacy measurement with PANSS scale, PSP, and social functioning score, and safety observations. Descriptive statistics were performed to identify the retention rate at each visit as well as the symptomatic remission rate. Summary statistics of average doses the subjects received were based on all subjects participating in the study. Results: A total of 480 patients were enrolled. Among them, 426 patients (88.8%) had evaluation at week 4 and 350 (72.9%) completed the 12-week evaluation. Patients with at least moderate severity of schizophrenia were evaluated as “mild” or better on PANSS scale by all 8 items after 12 weeks of treatment with paliperidone ER. There was significant…

    Typical antipsychotic drugs (neuroleptics) work by reducing dopamine within schizophrenia sufferers. Common forms of neuroleptics include drugs such as Thorazine, Prolixin and Haldol. These drugs actually block the activity of the dopamine neurotransmitter, the drugs take effect within 48 hours but it can be several weeks before a noticeable difference is seen with symptom reduction. Barondes’s (1993) research looked into balancing the dosage of the drug, lowering the drug dosage reduced the side effects but also reduced the effectiveness of the drug meaning it wouldn’t necessarily be a successful or quick recovery compared to high dosages of the neuroleptics. Although this showed clear evidence for the effectiveness of neuroleptics in combating schizophrenia, emphasized when changing the dosage changes the effectiveness of the neuroleptics.…

    The development and use of Antipsychotic drugs to treat schizophrenia support the dopamine hypothesis. The drugs work by blocking activity of dopamine and have been shown to alleviate symptoms of schizophrenia, such as hallucinations, delusions and thinking problems associated with the disorder. This is because by reducing dopamine activity helps to maintain a constant level in guiding attention, leading to a decrease in key schizophrenic symptoms of hallucinations and delusions because they can be caused by being overly attentive. Statistics increase the reliability of the biological explanation of the dopamine hypothesis for explaining schizophrenia; as they show Antipsychotics have a 60% success rate. Therefore, this shows a link between high levels of dopamine activity and schizophrenia, as antipsychotics work by blocking the dopamine activity. This has led to more…

    When we think of childhood, most of us have an image embedded in our minds of a place blessed with ceaseless joy and happiness. It’s a time in our life during which an individual is free of responsibilities but subsequently begins to learn right from wrong. Bless Me, Ultima by Ruldolfo Anaya, however, offers a differing viewpoint on childhood and adolescence; one denoted by an inauguration into adulthood and maturity. Antonio Márez, the protagonist of Bless Me, Ultima, is a six year old boy whose childhood is marked by many conflicts and events that administer a lasting impact on his life. Ruldolfo Anaya, through the character of Antonio and his brothers, presents to the reader a childhood marked by a loss of innocence and progression into adulthood through the development of moral independence, expectations from family and culture of what one has to become in the future, and development of the judgment of what is good and what is evil/or a sin. Through the culmination of these three factors, we can see how Anaya’s representation of childhood contributes to the meaning of this fine piece of literature, which is one of a transition from innocence to experience through moral independence.…

    The vast majority of people who suffer from schizophrenia will receive some form of treatment to try and diminish their symptoms. There are drug therapies that help patients to function as well as possible, and were founded in the 1950's when the drugs were given to hospital patients to try and calm their anxiety before surgery but were also found to relieve the symptoms of schizophrenia and so consequently were used for treatment of schizophrenia. Antipsychotics were used to combat the positive symptoms of schizophrenia e.g. hallucinations and auditory hallucinations, which are come from having an overactive dopamine system in the brain.…
