Researchers are evaluating whether skipping additional axillary treatment for patients with early-stage breast cancer who had cancer in their lymph nodes before chemotherapy but show no remaining cancer in those nodes after treatment is as effective as the standard approach. This study focuses on disease-free survival and reducing the risk of lymphoedema five years after treatment. It is a randomized, open, multicenter trial including patients with specific breast cancer stages and confirmed nodal metastases. Participants will all receive standard therapies including HER2-targeted treatment, endocrine therapy, and radiotherapy to the breast or chest wall if needed. They will be randomly assigned to one of two groups one group will not get further axillary treatment such as lymph node removal or radiotherapy, while the other group will receive these axillary treatments according to local guidelines. Follow-up visits will occur annually for at least five years. During the study, participants will undergo assessments to monitor disease-free survival and self-reported lymphoedema using specific questionnaires. Additional evaluations include arm function, quality of life, recurrence rates, survival, and cost-effectiveness analyses. The total study duration is planned for 120 months, including setup, recruitment, follow-up, analysis, and reporting.

The trial investigates the role of ixazomib in patients with relapsed multiple myeloma who have previously undergone autologous stem cell transplant ASCT. It is a phase III, randomized, controlled, multi-center, open-label study aiming to assess whether adding a proteasome inhibitor to salvage ASCT conditioning improves depth of response and how consolidation and maintenance therapy influence the durability of response. The study also evaluates overall survival, progression-free survival, response rates, minimal residual disease, toxicity, and quality of life. Participants first receive re-induction therapy with 4 to 6 cycles of ixazomib, thalidomide, and dexamethasone ITD, each cycle lasting 28 days. Those achieving at least stable disease are randomly assigned to receive either conventional ASCT using melphalan alone or augmented ASCT combining melphalan with ixazomib. After ASCT, participants with minimal response or better are further randomized to either receive consolidation with 2 cycles of ITD followed by ixazomib maintenance until disease progression or no further treatment. During the study, participants undergo regular assessments including response evaluation 100 days post-ASCT, monitoring of progression-free survival for up to 120 months, and measurement of minimal residual disease at several time points. Safety and toxicity are closely monitored throughout re-induction, post-ASCT, consolidation, and maintenance phases. Quality of life questionnaires are completed at baseline, post-re-induction, post-ASCT, and during follow-up visits up to 24 months. The study plans to register 406 participants, with 284 randomized at the first stage and 248 at the second stage.
