A Dose Finding Study of [177Lu]Lu-DOTA-TATE in Newly Diagnosed Glioblastoma in Combination with Standard of Care and in Recurrent Glioblastoma as a Single Agent
Given the growing research on the multidimensional benefits of compassion cultivation, the current study sought to explore the feasibility and effectiveness of a Compassionate Mind Training intervention for Teachers (CMT-T) on teachers' psychological distress, wellbeing and compassion to self and others using a randomised controlled and stepped wedge design. The CMT-T specifically aimed at promoting positive affect and satisfaction with professional life and reducing symptoms of depression, anxiety, stress, and burnout, by increasing the flows of compassion (for self, for others and from others), self-compassion and compassion to others motivations and actions, and by diminishing fears of compassion (for self, for others and from others) and self-criticism. Furthermore, the present study aimed to explore the impact of the CMT-T on heart rate variability (HRV), an indicator of vagal regulatory activity and a physiological marker of a person's ability to flexibly respond to environmental challenges and regulate emotional responses. In light of previous research pointing to the role of individual differences in self-criticism on how individuals respond to compassion-based interventions, this study aimed to examine how self-criticism would influence the effects of the CMT-T intervention. Baseline self-criticism was hypothesized to impact the CMT-T effects on the primary and secondary outcome variables. In addition, the current study aimed to examine whether the effects of attending the CMT-T were sustained at 3-month post-intervention. Given that the inter-relationship between the three flows of compassion (i.e., compassion for others, being open to compassion from others, and self-compassion) is a key aspect of the CMT approach, the study sought to explore whether the associations between the flows of compassion would change from before to after the CMT-T, particularly whether these were strengthened after training. Finally, this study aimed to examine the mechanisms of change for the primary outcome variables at post-intervention. It is hypothesized that the changes occurred after the CMT-T intervention were mediated by changes in competencies for compassion for self, for others and from others, decreased levels fears of compassion for self, from others and from others, enhanced affect regulation, diminished self-criticism.
The purpose of the study is to compare the efficacy of zanubrutinib plus obinutuzumab versus lenalidomide plus rituximab (R^2) in participants with relapsed/refractory (R/R) follicular lymphoma (FL), as measured by progression-free survival as determined by an independent review committee in accordance with the 2014 modification of the International Working Group on non-Hodgkin lymphoma (NHL) Criteria based on n positron emission tomography and computed tomography (PET/CT), and to compare the efficacy of zanubrutinib plus rituximab versus R^2 in participants with R/R marginal zone lymphoma (MZL), as measured by progression free survival (PFS) assessed by IRC in accordance with CT-based Lugano 2014 Criteria.
This study aims to analyze which cognitive training experimental condition - Tablet versus Kinect - results in greater cognitive, mood, quality of life, and functional gains in a sample of chronic psychiatric patients.
Helicobacter pylori is a pathogenic bacteria transmitted from individual to individual, being scientifically recognized as an agent who causes persistent inflammatory activity on the gastric mucosa. This pathogen represents a Global Health problem, as shown in a systematic review by Hooi et al. Besides regional differences, more that half of the world population is expected to have already been infected by this bacteria. In Portugal, research studies estimate that more than 80% of the adult population has already contacted with H. pylori. H. pylori infection is associated with active chronic gastritis in every colonized patient, what may consequently lead to peptic ulcer disease, atrophic gastritis, gastric adenocarcinoma and mucosa-associated lymphoid tissue (MALT) lymphoma. For that reason, H. pylori infection is considered to be a disease, independently of the presence of gastrointestinal symptoms. Additionally, H. pylori has been classified as a confirmed carcinogen (class I) by the International Agency for Research, being responsible for carcinogenic pathways conducting to both gastric adenocarcinoma and lymphoma. This fact gains a particular relevance taking into account that gastric cancer is one of the most prevalent cancers worldwide. On other hand, more than 75% of the gastric cancers occur following H. pylori infection. Thus, H. pylori eradication constitutes an essential Public Health measurement, being inclusively considered a cost-effective method to decrease the gastric cancer burden, by promoting pre-malignant lesions regression, such as atrophic gastritis, and by delaying the disease progression in case of intestinal metaplasia or dysplasia. Maastricht V consensus is a document updated in 2016, including the major recommendations regarding H. pylori diagnosis, follow-up and treatment. It highlights the emergence of antibiotic resistances and how they must influence clinical practice, namely the choice of antibiotic regimens, as successful eradication has become less frequent with more prevalent antibiotic resistances. This is the case of clarithromycin and metronidazol, both currently recommended as first-line options by the Portuguese Society of Gastroenterology. In fact, a systematic review conducted in 2018, aiming to evaluate antibiotic resistances on the Portuguese population observed that clarithromycin, metronidazole and double resistance occurred in 42%, 25% and 20% of the individuals, respectively. Nowadays, Maastricht V guidelines recommend quadruple regimens containing bismuth, such as Pylera (r), as the first-line option in areas with significant double resistance to metronidazole and clarithromycin. Another option currently being investigated is the double therapy with amoxicillin in high doses and proton pump inhibitor. This has become a particularly attractive alternative due to its efficacy, good tolerability and significantly low resistance (<1%) among the European population. The aim of this clinical trial is to compare both regimens - pylera (r) and high-dose amoxycillin - in H. pylori eradication, regarding their efficacy, tolerability and side effects, in order to asses viable therapeutic options in a population with progressively increasing resistances to alternative regimens currently recommended.
In Portugal, there is an increase in cases of depression (from 6.9% to 9.8%) and anxiety (from 3.5% to 6.5%), among those enrolled in health care centers. Although the prevalence of both disorders' peaks in older adulthood, depression and anxiety often have their onset in youth. The high prevalence of psychological morbidity has been a cause for concern, given the associations between depression and anxiety in youth and other chronic mental disorders, stress, physical health problems and poorer quality of life (QoL), and physical disorders in older age. The prevention of psychological morbidity in young people is crucial to reduce its adverse effects on young adults' development, school performance, social functioning, and to prevent its harmful impact on QoL. Cognitive behavioral therapy is considered the most effective intervention for the treatment of anxiety and depression in young people. In this study, a behavioral relaxation technique, i.e., relaxation, will be used. This technique has positive effects on psychological morbidity, specially Schultz's autogenic relaxation training. Electrostimulation therapy, a non-invasive technique that uses electrical micro current for therapeutic purposes, is an innovative way of treating psychological morbidity, and has proven to be effective in reducing stress, depression and anxiety. Recently, studies found that cortical stimulation was associated with a reduction in depression, effects maintained after the treatment end. Also, there is evidence that there are improvements in depression, anxiety, pain and sleep, which were maintained after 4 treatment sessions. Considering the high incidence of psychological morbidity in emerging adulthood, as well as its harmful impact on adulthood, the importance of this research aimed at reducing psychological morbidity in young adults and promoting QoL throughout life stands out. This study aims to answer the question "Does an electrostimulation therapy intervention have an impact on psychological morbidity and QoL when compared to a cognitive behavioral intervention?", with the main objective of contributing to reducing psychological morbidity in young adults, as well as promoting their QoL.
The main purpose of this trial is to evaluate the efficacy of PTC923 in reducing blood phenylalanine (Phe) levels in participants with phenylketonuria as measured by mean change in blood Phe levels from baseline to Weeks 5 and 6 (that is, the average of each respective treatment dose 2-week period of double-blind treatment).
Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC), a group of lung cancers that have spread to nearby tissues or to other parts of the body. Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are proteins that help cells to grow and divide. A damage (also called mutation) to the building plans (genes) for these proteins in cancer cells leads to a production of abnormal EGFR and/or HER2. These abnormal proteins drive the growth and the spread of the cancer. Several EGFR and/or HER2 mutations exist in the cancer cells. The study treatment, BAY2927088, is expected to block the mutated EGFR and HER2 proteins which may stop the spread of NSCLC. The main purpose of this study is to learn: Escalation, Backfill, and Expansion Part: - How safe is BAY2927088 for the participants? - What is the highest dose of BAY2927088 that can be tolerated (maximum tolerated dose) by or given to (maximum administered dose) the participants? - How does BAY2927088 move into, through, and out of the bodies of the participants? For this, the researchers will measure the followings: - The number of participants with medical problems, also called adverse events and serious adverse events, and their severity - The number of participants who discontinue study treatment due to an adverse event. - The highest dose of BAY2927088 that the participants can take without having adverse events (maximum tolerated dose (MTD)) or the maximum dose that is tested and found to be safe for the participants in case MTD cannot be found out (maximum administered dose (MAD)) of BAY2927088 - Number of participants experiencing adverse events that prevent an increase in the dose of BAY2927088 (dose-limiting toxicities (DLTs)) at each dose level - The (average) total level of BAY2927088 in the blood (also called AUC) after receiving single or multiple doses of BAY 2927088 - The (average) highest level of BAY 2927088 in the blood (also called Cmax) after receiving a single or multiple doses of BAY2927088 Extension Part - How well does BAY 2927088 work in participants? For this, the researchers will measure the following: • Percentage of participants whose cancer completely disappears (complete response) or reduces by at least 30% (partial response) after taking the treatment (also known as objective response rate (ORR)). This will be assessed by doctors other than the study doctor. This study has 4 parts: - The escalation part aims to find the maximum daily amount (dose) of BAY2927088 that participants can receive. - The backfill part aims to test the doses of BAY2927088 that are considered safe in the escalation part by giving it to more participants. This will help find optimal doses of BAY 2927088 that work well and are safe to be tested in the next part. - The expansion part aims to determine the dose of BAY2927088 to be tested in further studies. - The extension part aims to determine whether the selected dose of BAY2927088 from the expansion part works well. The participants in this study will take the study treatment BAY2927088 in 3-week periods called "cycles". They will in general take BAY2927088 once or twice daily as a liquid/tablet by mouth until their cancer gets worse, they have medical problems, they leave the study, or the study is terminated. Participants will have no more than 5 visits per cycle. During the study, the study team will: - take blood and urine samples, - check the status of the cancer by doing computed tomography (CT) or magnetic resonance imaging (MRI) scans, - check the participants' overall health and heart health, - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is considered "serious" when it leads to death, puts the participant's life at risk, requires hospitalization, causes disability, causes a baby being born with medical problems, or is medically important.
Researchers are looking for a better way to treat women who have hot flashes after women have been through the menopause. Hot flashes are caused by the hormonal changes that happen when a woman's body has been through the menopause. Menopause is when women stop having a menstrual cycle, also called a period. During the menopause, the ovaries increasingly produce less sex hormones as a result of the natural ageing process and related hormonal adjustments. The decline in hormone production can lead to various symptoms which, in some cases, can have a very adverse effect on a menopausal woman's quality of life. The study treatment, elinzanetant, was developed to treat symptoms caused by hormonal changes. It works by blocking a protein called neurokinin from sending signals to other parts of the body, which is thought to play a role in starting hot flashes. There are treatments for hot flashes in women who have been through the menopause, but may cause medical problems for some people. In this study, the researchers will learn how well elinzanetant works compared to a placebo in women who have been through the menopause and have hot flashes. A placebo looks like a treatment but does not have any medicine in it. To compare these study treatments, the doctors will ask the participants to record information about the participants' hot flashes in an electronic diary. The researchers will study the number of hot flashes the participants have and how severe the hot flashes are. The researchers will look at the results from before treatment, after 4 weeks, and after 12 weeks of treatment. The participants in this study will take two capsules of either elinzanetant or the placebo once a day. The participants who take elinzanetant will take it for 26 weeks. The participants who take the placebo will take it for 12 weeks and then take elinzanetant for the next 14 weeks. During the study, the participants will visit the site approximately 9 times and perform 1 visit by phone. Each participant will be in the study for approximately 36 weeks. The treatment duration will be 26 weeks. During the study, the participants will: - record information about the participants' hot flashes in an electronic diary - answer questions about the participants' symptoms The doctors will: - check the participants' health - take blood samples - ask the participants questions about what medicines the participants are taking and if the participants 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 doctors do not think the adverse events might be related to the study treatments.
