This is a cohort study, applied research and T3 translational genomics to estimate the impact of genetic risk for breast cancer detection in the screening program. The study group base consists of 28 389 female participants, currently in the age-group 22-79, in the Biobank of Estonian Genome Centre. The study is aimed to demonstrate the usability of personalised approach for adjusting and stratifying screening recommendations, based on predicted genetic risk estimates for breast cancer in the situation, where the genome data could be available from all women who have given informed consent for that. The project includes both the detection of moderate and high hereditary breast cancer risk carriers as well as high risk polygenic risk-score (consisting several single nucleotide polymorphisms) carriers among healthy individuals for application of personalised prevention and screening strategies.
The purpose of this open-label extension (OLE) study is to evaluate the safety and efficacy of etrasimod in participants with moderately to severely active ulcerative colitis (UC) who previously received double-blind treatment (either etrasimod 2 mg per day or placebo) during participation in one of the qualified Phase 3 or Phase 2 double-blind, placebo-controlled parent studies including but not limited to: (APD334-301 [NCT03945188] or APD334-302 [NCT03996369] or APD334-210 [NCT04607837]).
The pilot study collects the experience of previously successful treatment of infants, children and young adults, with ALL from a number of well-renowned study groups into a new platform protocol, which is both a comprehensive system for stratification and treatment of ALL in this age-group as well as the basis for several randomised trials included in the study-design. The pilot study is implemented as a master protocol without study specific interventions, thus as an observational study. The pilot study is for countries/study-groups who intend to join ALLTogether1 (including experimental interventions). For these countries the pilot study is crucial to optimise diagnostics, registration systems, collaborations with vendors, logistics and data-checks before starting the main study. The study only includes "standard of care" treatment included in the master protocol.
AML and MDS-EB2 are malignancies of the bone marrow. The standard treatment for these diseases is chemotherapy. Patients participating have a special type of this disease because the leukemia cells (blasts) have developed an error in the genetic material (DNA). This error is called an IDH1 mutation or an IDH2 mutation (a mutation is a change in the DNA), which leads to changes in specific substances in the leukemia cells. This trial will investigate whether the addition of the new drugs Ivosidenib (for patients with IDH1 mutation) or Enasidenib (for patients with IDH2 mutation) to the standard treatment of chemotherapy controle the disease more effectively and for a longer period.

Study design Prospective randomized open labeled multicenter study Hypotheses 1. In asymptomatic patients with ≥ 10% of myocardial ischemia: PCI (Percutaneous Coronary Intervention) with latest generation of drug eluting stents is superior to optimal medical therapy in terms of relative reduction in MACCE (Major Adverse Cardiovascular and Cerebrovascular events). 2. In symptomatic patients with ≥ 5% of myocardial ischemia: PCI with latest generation of drug eluting stents is superior to optimal medical therapy (OMT) in terms of improved life quality measured as an increase of SAQ (Self Assessment Questionnaire) score of 8 points after 6 months. Inclusion Criteria - CTO in native coronary artery - Myocardial ischemia in a territory supplied by CTO assessed by nuclear imaging. - Age ≥18 yrs. - Able to provide written Informed consent and willing to comply with the specified follow-up contacts - Target artery ≥ 2.5 mm Prior to randomization all patients undergo 3 months of OMT. Subsequently the population will be divided into: Cohort A: Asymptomatic (CCS < 2 and SAQ QoL > 60) patients with myocardial ischemia (≥ 10% of LV) in a territory supplied by CTO Cohort B: Symptomatic patients (CCS class ≥ 2 and/or SAQ QoL score ≤ 60 after treating non CTO lesions and after OMT) with Myocardial ischemia (5% of LV) in a territory supplied a CTO Cohort C: patients enrolled but not randomized in cohort A or B Exclusion criteria (for both cohort A and B) - NSTEMI or STEMI within 1 month - Coronary anatomy not suitable for CTO-procedure - Coronary artery disease involving the left main/three-vessel disease with indication for CABG following heart team conference - Life expectancy < 2 years - Severe chronic pulmonary disease (FEV1 < 30 % of predicted value) - Contraindication to dual anti-platelet therapy - Pregnancy - eGFR < 30 mL/min/1.73 m2 - In multi-vessel disease: if it is deemed unsafe to treat the non-CTO lesion first. - Severe valvular heart disease Primary endpoint Cohort A: Composite endpoint of MACCE (all-cause mortality, stroke, any myocardial infarction, clinically driven revascularization*), hospitalization for heart failure or incidence of malignant arrhythmias. *CCS class ≥ 2 and/or QoL score < 60. Same criteria used as for allocation to Cohort B Cohort B: SAQ Quality of Life Assessment after 6 months. Number of patients 1,560 (1200 in cohort A/360 in cohort B Follow up time Cohort A: 5 years Cohort B: 6 months
Break the Cycle is a two-session, one-on-one, in-person intervention study designed to reduce the role persons who inject drugs (PWID) play initiating non-PWID into injection drug use. Study implementation is at two sites: New York City and Tallinn, Estonia. At baseline, quantitative data are collected via a structured computer-assisted personal interview, after which the intervention is conducted. At the 6-month follow-up, a modified version of the interview is repeated. The study uses a pre- versus post- design to compare the proportion of participants who helped with first injections, and who promoted injecting among non-PWID, in the 6 months prior to baseline with the proportions at the 6-month follow-up. Based on previous research on the intervention and on the underlying theory of motivational interviewing, increases in helping and promoting behaviors between baseline and follow-up would indicate that the intervention was not effective regardless of their effect size. Accordingly, the hypotheses that the intervention will produce reductions in assisting with first injections and engaging in injection promoting behaviors will be evaluated using one-tailed statistical tests. Break the Cycle intervention follows a motivational interviewing approach to enhance current injectors' motivation and skills to avoid helping with and promoting first injections among non-PWID. The intervention's core is a discussion between an interventionist and each participant on the following eight topics: the participant's first time injecting drugs; the participant's exposures to situations where helping with others' first injections is an option, and the extent to which they have helped; PWIDs' behaviors that might encourage non-PWID to inject for the first time; the range of risks associated with injection drug use; role-playing scenarios in which the participant develops behaviors and scripts for avoiding or refusing requests to initiate others into injection drug use; role- playing talking with other PWID about not encouraging non-PWID to start injecting; imparting safer injection practices when helping with a first injection seems like the best option; and receiving training in and using Narcan to reverse overdoses.
The purpose of this study is to evaluate the long-term safety and efficacy of pembrolizumab (MK-3475) in participants from previous Merck pembrolizumab-based parent studies who transition into this extension study. This study will consist of three phases: 1) First Course Phase, 2) Survival Follow-up Phase or 3) Second Course Phase. Each participant will transition to this extension study in one of the following three phases, depending on the study phase they were in at the completion of the parent study. Participants who were in the First Course Phase of study treatment with pembrolizumab or lenvatinib in their parent study will enter the First Course Phase of this study and complete up to 35 doses or more every 3 weeks (Q3W) or 17 doses or more every 6 weeks (Q6W) of study treatment with pembrolizumab or a pembrolizumab-based combination or lenvatinib according to arm assignment. Participants who were in the Follow-up Phase in the parent study (post-treatment or Survival Follow-up Phase) will enter the Survival Follow-up Phase of this study. Participants who were in the Second Course Phase in their parent study will enter Second Course Phase of this study and complete up to 17 doses Q3W or 8 doses Q6W of study treatment with pembrolizumab or a pembrolizumab-based combination according to arm assignment. Any participant originating from a parent trial where crossover to pembrolizumab was permitted upon disease progression may be eligible for 35 doses as Q3W or 17 doses Q6W of pembrolizumab (approximately 2 years), if they progress while on the control arm and pembrolizumab is approved for the indication in the country where the potential eligible crossover participant is being evaluated.
