About this study

Official title: Selective Estrogen Receptor Modulators - Adjunctive Treatment for Negative and Cognitive Symptoms of Schizophrenia in Postmenopausal Women

The aim of the project is to assess the efficacy of Adjunctive Selective Estrogen Receptor Modulators (Raloxifene) on Negative and Cognitive symptoms of Schizophrenia in Postmenopausal Women.

For postmenopausal women with schizophrenia, current research suggests that these people can be treated with estrogen, which can reduce cardiovascular and reproductive tissue problems, help sleep and improve mood. In addition, cognitive problems in this group of people can also be helped. Raloxifene is a Selective Estrogen Receptor Modulator (SERM), which means that it can affect the central nervous system (CNS) effects of estrogen (eg. improving emotional symptoms, memory, information processing and concentration), without adversely affecting reproductive tissue/organs such as breast, uterus and ovaries. The investigators are conducting a double-blind, placebo controlled, 12 weeks study comparing the negative symptoms and cognitive functions in postmenopausal women with schizophrenia in both groups. One group will receive clozapine plus 60mg Raloxifene (Usage: take 60mg Raloxifene tablets half an hour after breakfast every day, that is, take 1 tablet a day), while the second group will receive clozapine plus oral placebo (Usage: take 1 placebo half an hour after breakfast every day).

Hypothesis 1: Adjuvant raloxifene therapy in postmenopausal women with schizophrenia can improve negative symptoms, as measured on the rating scales, compared with the women receiving adjunctive placebo.

Hypothesis 2: The cognitive function of postmenopausal female schizophrenic patients treated with raloxifene would be better than that of the placebo group.

Hypothesis 3: That the Raloxifene group has less adverse reactions in postmenopausal women with schizophrenia.

Read the detailed description

Schizophrenia is a mental illness with unknown cause and difficult treatment which the global lifetime prevalence rate of about 1%. The core symptoms of schizophrenia include positive symptoms, negative symptoms, and impairment of cognitive function. Positive symptoms in most patients after antipsychotic treatment can significantly alleviate after antipsychotic treatment, but negative symptoms and cognitive deficits persist. Unfortunately, the long-term prognosis and social function of patients mainly depend on the degree of the rehabilitation of negative symptoms and cognitive function. At present, clinical research domestic and overseas on the negative symptoms and cognitive function gradually increased, but end up with the poor consistency of research results. The reason is various, but in any case, improving the treatment strategy is still very important.

Epidemiological data suggest that the age of onset of female schizophrenia is later than men, most of which are onset abruptly, and females have higher susceptibility to mental illness and relapse during the two important periods with hormonal changes. The first is in the postpartum, menopause is the second. It may be related to the lack of estrogen function. Therefore, we believe that the onset and symptoms of some female patients with schizophrenia are related to the dysfunction of estrogen. Many studies abroad have found that estrogen and selective estrogen receptor modulators have significant effects on female patients with schizophrenia, especially on negative symptoms and cognitive functions, but the clinical application is limited due to the potential side effects of estrogen.

Raloxifene is the second generation of selective estrogen receptor modulator, for the prevention and treatment of osteoporosis in postmenopausal women, which can significantly reduce the incidence of vertebral fractures. The common adverse drug reaction is slight increase in hot flash and leg cramps, and the most serious adverse drug reaction is venous thromboembolism. Past research has found that raloxifene can reduce the risk of decline in memory and attention, and taking raloxifene helps sleep. Current research suggests that as an adjuvant therapy, it can improve symptoms of menopausal women with schizophrenia (emotional symptoms, memory, information processing and storage), and will not negatively affect reproductive tissues or organs, such as breast, uterus and ovary.

According to the domestic and overseas research results, and based on the theoretical background of schizophrenia in estrogen insufficiency, we proposed randomized double-blind placebo-controlled study, in order to understand the effect of raloxifene on negative symptoms and cognitive function in adjuvant treatment of menopausal female patients with schizophrenia, meanwhile assess the adverse reactions after the treatment, provide the basis for clinical treatment of schizophrenia patients with negative symptoms and cognitive impairment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Response in negative symptoms

    A response in negative symptoms was defined as improvement of ≥20% compared with baseline PANSS negative score (12 weeks)

    Measured: baseline, week 4, 8, 12

Secondary outcomes (4)
  1. Clinical Assessment Interview for Negative Symptoms(CAINS)

    The CAINS is a scale of the clinical assessment interview for negative symptoms of schizophrenia.The CAINS includes 16 items covering motivation and pleasure across social (five items), vocational (three items), and recreational life (three items) domains, as well as emotion expression and speech (five items).All items were rated on a scale of 0-4, with higher scores reflecting greater impairment.

    Measured: baseline, week 4, 8, 12

  2. Scale for the Assessment of Negative Symptoms (SANS)

    The SANS are the most widely used symptom rating scales in schizophrenia research. SANS Total (Composite) score = sum(of SANS items 1-7, 9-12, 14-16, 18-21, and 23-24).The total range is from 0-120 scores.

    Measured: baseline, week 4, 8, 12

  3. Repeatable Battery for the Assessment of Neuropsychological Status(RBANS)

    The RBANS is a brief cognitive screening battery consisting of 12 subtests which are used to create Index scores in the following five cognitive domains: Immediate Memory, Visuospatial/Constructional Skills, Language, Attention, and Delayed Memory. A total score is created by summing the five index cores which are thought to represent one's current neuropsychological status.

    Measured: baseline, week 12

  4. Hormone level change

    Hormone level change over study duration (12 weeks)

    Measured: baseline, week 4, 8, 12

The record says: finished, as of the sponsor's last update on 6 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Response in negative symptoms (time frame: baseline, week 4, 8, 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Sep 2019.
