Researchers are investigating new treatment options for breast cancer that is hormone receptor-positive HR and human epidermal growth factor receptor 2-negative HER2-, specifically for cases that are unresectable locally advanced or metastatic. This type of breast cancer involves cancer cells that depend on hormones like estrogen or progesterone and have low HER2 protein levels. The study focuses on comparing the effects of patritumab deruxtecan against chemotherapy or trastuzumab deruxtecan in patients whose cancer has progressed despite prior treatments. Participants receive either patritumab deruxtecan through intravenous infusions every three weeks for about 13 months or a treatment chosen by their physician, which may include various chemotherapy drugs or trastuzumab deruxtecan, administered according to specific schedules for up to 13 months. The study is randomized and open-label, meaning participants are randomly assigned to one of the treatment groups, and both the patients and researchers know which treatment is given. Throughout the study, participants undergo regular assessments to monitor cancer progression and overall survival for up to approximately 85 months. Researchers evaluate tumor response, duration of response, and changes in quality of life using standardized questionnaires. Safety is carefully monitored by recording adverse events and treatment discontinuations. The goal is to understand if patritumab deruxtecan can improve outcomes compared to current treatment options.

Researchers are evaluating treatments for germinal center B-cell-like diffuse large B-cell lymphoma GCB DLBCL, a fast-growing blood cancer affecting immature B-cells. The study compares two treatment combinations to see if more people respond to zilovertamab vedotin MK-2140 plus R-CHP versus polatuzumab vedotin plus R-CHP. This Phase 2 trial aims to assess the effectiveness and safety of these regimens in participants with newly diagnosed GCB DLBCL. Participants receive either zilovertamab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone R-CHP, or polatuzumab vedotin combined with R-CHP. Treatments are given by intravenous infusion on Day 1 of each 3-week cycle for up to 6 cycles, approximately 4 months, with prednisone or prednisolone taken orally for 5 days of each cycle. For participants with high-risk DLBCL, up to 2 additional cycles of rituximab or biosimilar are given. During the study, participants are monitored for response to treatment using Lugano Response Criteria, with follow-up lasting up to about 31 months for the primary outcome. Secondary outcomes include progression-free survival, overall survival, event-free survival, duration of complete response, adverse events, and quality of life assessments. Safety and health status are regularly checked through exams, lab tests, and questionnaires over several years, with total study participation extending up to 7 years.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab monotherapy as the first-line treatment for patients with metastatic non-small cell lung cancer mNSCLC whose tumors express high levels of PD-L1. This Phase III, randomized, double-blind, multicenter global study focuses on patients with mNSCLC without certain genetic mutations who are suitable for this treatment approach. Participants are randomly assigned to receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle.
