There are about 199 clinical studies being (or have been) conducted in Kazakhstan. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Abstract Cardiac surgery in adults is associated with the occurrence of post-operative complications. Even minor complications can increase the cost of their treatment. Given the potentially preventable nature of a number of these postoperative complications, preventive methods should be used to improve outcomes after cardiac surgery. One of them, is the choice of anaesthetic technique. Objectives: To evaluate the effects of sevoflurane, isoflurane and propofol on blood oxygen transport function and body energy expenditure during cardiac surgery in adults. Materials and methods. A total of 90 patients were included in the study. All patients were divided into 3 groups: 1- (n=30) included patients who were anesthetized with propofol. The second group (n=30) consisted of patients who underwent sevoflurane inhalation anaesthesia. Group 3 (n=30) was treated with isoflurane. All patients underwent coronary artery bypass grafting under cardiopulmonary bypass.
Researchers are looking for a better way to prevent an ischemic stroke which occurs when a blood clot travelled to the brain in people who within the last 72 hours had: - an acute stroke due to a blood clot that formed outside the heart (acute non-cardioembolic ischemic stroke), or - TIA/mini-stroke with a high risk of turning into a stroke (high-risk transient ischemic attack), and who are planned to receive standard of care therapy. Acute ischemic strokes or TIA/mini-stroke result from a blocked or reduced blood flow to a part of the brain. They are caused by blood clots that travel to the brain and block the vessels that supply it. If these blood clots form elsewhere than in the heart, the stroke is called non-cardioembolic. People who already had a non-cardioembolic stroke are more likely to have another stroke. This is why they are treated preventively with an antiplatelet therapy, the current standard of care. Antiplatelet medicines prevent platelets, components of blood clotting, from clumping together. Anticoagulants are another type of medicine that prevents blood clots from forming by interfering with a process known as coagulation (or blood clotting). The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care without increasing the risk of bleeding. The main purpose of this study is to learn whether asundexian works better than placebo at reducing ischemic strokes in participants who recently had a non-cardioembolic ischemic stroke or TIA/mini-stroke when given in addition to standard antiplatelet therapy. A placebo is a treatment that looks like a medicine but does not have any medicine in it. Another aim is to compare the occurrence of major bleeding events during the study between the asundexian and the placebo group. Major bleedings have a serious or even life-threatening impact on a person's health. Dependent on the treatment group, the participants will either take asundexian or placebo as tablets once a day for at least 3 months up to 31 months. Approximately every 3 months during the treatment period, either a phone call or a visit to the study site is scheduled on an alternating basis. In addition, one visit before and up to two visits after the treatment period are planned. During the study, the study team will: - Check vital signs such as blood pressure and heart rate - Examine the participants' heart health using an electrocardiogram (ECG) - Take blood samples - Ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. In addition, the participants will be asked to complete a questionnaire on quality of life at certain time points during the study.

Researchers are looking for a better way to treat women with, or at high risk for developing hormone-receptor positive breast cancer, who have vasomotor symptoms (VMS), a condition of having hot flashes caused by anti-cancer therapy. VMS, also called hot flashes, are very common medical problems in women with hormone-receptor (HR)-positive breast cancer, who are receiving anti-cancer therapy. HR-positive breast cancer is a type of breast cancer, which has hormone-receptors (proteins) for female sex hormones estrogen and/or progesterone. These hormone-receptors may attach to hormones like estrogen and progesterone and thereby help cancer cells to grow and to spread. Treatments that stop these hormones from attaching to these receptors are currently used to slow or stop the growth of HR-positive breast cancer. It is already known that women with HR-positive breast cancer benefit from this treatment. However, hot flashes are common medical problems related to this therapy. They negatively affect quality of life of many women and may lead to discontinuation (stopping) of this therapy. The study treatment, elinzanetant is being developed to treat hot flushes. It works by blocking a substance called neurokinin from sending signals to other parts of the body, which is thought to play a role in starting hot flashes. The main purpose of this study is to learn more about how well elinzanetant helps to treat hot flashes caused by anti-cancer therapy in women with or at high risk for developing HR-positive breast cancer compared to placebo. A placebo is a treatment that looks like a medicine but does not have any medicine in it. To answer this, the doctors will ask the participants to record information about their hot flashes before treatment start and at certain time points during the treatment in an electronic diary. The researchers will then assess possible average changes in number and severity of hot flashes after 4 and 12 weeks of treatment. To see how safe elinzanetant is compared to placebo. The study will collect information about the number of participants who have medical problems after taking treatment. The study participants will be randomly (by chance) assigned to 2 treatment groups, A and B. The participants from treatment group A will take elinzanetant. The participants from treatment group B will start with placebo and then switch to elinzanetant. All participants will continue taking the anti-cancer therapy they have been using when entering the study. Dependent on the treatment group, the participants will either take elinzanetant or placebo as capsules by mouth once a day. After 12 weeks, the participants who have initially received placebo will switch to take elinzanetant for the remaining 40 weeks. Each participant will be in the study for approximately 62 weeks. The treatment duration in the study will be 52 weeks. There will be up to 12 visits to the study site and 6 phone calls in between. Participants who completed the 52 weeks treatment phase, will be offered to continue treatment for another 2 years. Visit frequency: every 24 weeks until week 152. During the study, the participants will: - record information about their hot flashes - answer questions about their quality of life and other symptoms. The doctors and their study team will: - check the participants health and vital signs - take blood and urine samples - examine heart health using electrocardiogram (ECG) - examine pelvic organs like womb or ovaries using a trans vaginal ultrasound scan to see images of these organs - make images of the breast using x-ray (mammogram), a type of radiation that passes through the body to make images of the inside and/or by using ultrasound (if applicable) - check the health of the participant's cervix (neck of the womb) by taking a small sample of cells (smear test) for an analysis called cervical cytology (if applicable) - take an endometrial biopsy, a small piece of tissue from the lining of the womb (called the endometrium) for analysis. - ask the participants questions about what medicines they are taking and if they are having adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. About 4 weeks after the participants take their last treatment, the study doctors and their team will check the participants' health.
Central Asia (CA) represents the most rapidly growing HIV epidemic region worldwide, concentrated in people who inject drugs (PWID) and their sexual partners, and scaling up opioid agonist therapies (OAT) in this region is the most cost-effective strategy to prevent new HIV infections, and more effective when combined with antiretroviral therapy (ART). The investigators propose to use the Network for the Improvement of Addiction Treatment (NIATx) implementation strategy to scale-up OAT in three diverse Central Asian countries (Kazakhstan, Kyrgyzstan, Tajikistan) and guided by the Exploration-Planning-Implementation-Sustainment (EPIS) framework. Understanding the trajectories of implementation and scale-up in this context may emerge through creating communities of practice, especially when cohesion and competence evolves, and may guide other healthcare delivery challenges in the region (e.g., HIV, TB); as well as build important regional expertise and understanding implementation trajectories should help support OAT program sustainability.
