New Research Horizons in Duarte

This month, Duarte saw the launch of 6 new clinical trials, a decrease compared to the 16 trials that opened in May 2026. Despite this dip, these new studies bring important research opportunities to the community. Over the past six months, the number of new trials has fluctuated, with 7 in January, 7 in February, 4 in March, 6 in April, and 17 in May, indicating a consistent, albeit variable, flow of new research.

The new trials are exploring a range of conditions, primarily focusing on various cancers. These include advanced cutaneous melanoma, anatomic stage IV breast cancer AJCC v8, clinical stage III and IV cutaneous melanoma AJCC v8, ER-positive HER2-negative breast cancer, glioblastoma, hematopoietic and lymphatic system neoplasm, high grade sarcoma, lung carcinoma, and malignant solid neoplasm. The majority of these new studies are categorized as "OTHER" or "PROCEDURE" based on type, with some involving "BIOLOGICAL" or "DRUG" interventions.

Two notable new trials this month highlight significant advancements:

• AstraZeneca is sponsoring a notable Phase 3 study, NCT07647328, "A Phase IIIb Study to Evaluate Camizestrant Plus Ribociclib in ER-positive, HER2-negative Advanced Breast Cancer." This trial aims to enroll 150 participants to investigate the efficacy, safety, and tolerability of camizestrant in combination with ribociclib for patients with ER+ HER2- breast cancer who have not received prior systemic treatment for advanced disease.
• City of Hope Medical Center is leading NCT07650656, "Fluorescence-Guided Surgical Resection for Reducing Unexpected Positive Margins in Patients With Sarcoma, SarcoSIGHT Trial." This Phase 2 trial, designed for 22 participants, compares standard surgical resection to fluorescence-guided surgical resection using indocyanine green and fluorescence imaging, with the goal of reducing unexpected positive margin rates in sarcoma patients.
