Researchers are evaluating two types of radiation treatments for women with small, node-negative breast cancer (3 cm or smaller) after breast-conserving surgery. The study aims to find out if partial breast irradiation (PBI) given once a day over one week is not worse than whole breast irradiation (WBI) in preventing cancer from coming back locally and if it leads to better cosmetic outcomes as assessed by patients three years after treatment. This is a phase 3 randomized trial focusing on the comparison of these two radiation approaches. Participants will be randomly assigned to receive either PBI or WBI. Both treatments deliver a total radiation dose of 26 Gy divided into 5 daily sessions over 5 to 7 days (up to 8 days allowed due to holidays). The radiation is carefully targeted to the appropriate breast area, and the study is single-blinded so that patients do not know which treatment they receive to avoid bias in cosmetic assessments. Treatment planning includes using CT imaging and surgical markers for accurate delivery. During the study, participants will be monitored annually for five years to check for local cancer recurrence. Cosmetic outcomes will be assessed by patients themselves at three and five years post-treatment. Other evaluations include tumor characteristics and receptor status, and treatment safety will be observed. The total participation involves follow-up over several years to understand long-term effects of the treatments.

Researchers are conducting a two-part, phase 2b/3 study to evaluate CSL300 (Clazakizumab) in adults with end stage kidney disease (ESKD) undergoing dialysis who have systemic inflammation and either atherosclerotic cardiovascular disease (ASCVD) or diabetes. The study aims to determine the best dose of CSL300 and assess its effects on cardiovascular outcomes and safety in this population. This multicenter, randomized, double-blind, placebo-controlled trial targets patients with elevated inflammation markers and significant health risks due to their conditions. In the first part (phase 2b), the study focuses on finding the appropriate dose of CSL300 compared to placebo. CSL300 is given through intravenous (IV) administration. The second part (phase 3) evaluates the impact of CSL300 on cardiovascular events such as heart attack or cardiovascular death over approximately 5 years, continuing to compare CSL300 to placebo for safety and efficacy. The placebo matches CSL300's excipient content but lacks the active drug. Participants will undergo baseline and regular assessments for inflammation markers like high-sensitivity C-reactive protein (hs-CRP) up to 12 weeks in phase 2b, and long-term monitoring for cardiovascular outcomes in phase 3. The study involves ongoing safety evaluations and efficacy measurements during the entire follow-up period. This comprehensive approach helps researchers understand how CSL300 affects inflammation and cardiovascular health in patients with ESKD on dialysis.
