I-SPY TRIAL: Neoadjuvant and Personalized Adaptive Novel Agents to Treat Breast Cancer
NCT01042379
Recruiting
The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.

E-Mindfulness Approaches for Living After Breast Cancer
NCT06748222
Recruiting
NRG-CC015 is a prospective, randomized phase III clinical trial to evaluate the efficacy of two distinct digital approaches for delivering a mindfulness-based intervention: a live, instructor-led version delivered over Zoom (MAPs LO), and an app-based, self-paced version (MAPs App).

A Study to Evaluate the Efficacy and Safety of Inavolisib in Combination With Phesgo Versus Placebo in Combination With Phesgo in Participants With PIK3CA-Mutated HER2-Positive Locally Advanced or Metastatic Breast Cancer
NCT05894239
Recruiting
This study will evaluate the efficacy and safety of inavolisib in combination with Phesgo (pertuzumab, trastuzumab, and rHuPH20 injection for subcutaneous use) compared with placebo in combination with Phesgo, as maintenance therapy, after induction therapy in participants with previously untreated HER2-positive advanced breast cancer (ABC).

Testing Radiation and HER2-targeted Therapy Versus HER2-targeted Therapy Alone for Low-risk HER2-positive Breast Cancer
NCT05705401
Recruiting
This Phase III trial compares the recurrence-free interval (RFI) among patients with early-stage, low risk HER2+ breast cancer who undergo breast conserving surgery and receive HER2-directed therapy, and are randomized to not receive adjuvant breast radiotherapy versus those who are randomized to receive adjuvant radiotherapy per the standard of care.

Evaluating the Addition of Adjuvant Chemotherapy to Ovarian Function Suppression Plus Endocrine Therapy in Premenopausal Patients With pN0-1, ER-Positive/HER2-Negative Breast Cancer and an Oncotype Recurrence Score Less Than or Equal to 25
NCT05879926
Recruiting
This Phase III Trial will determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive breast cancer-free survival (IBCFS) among premenopausal, early- stage breast cancer (EBC) patients with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 (for pN0 patients) and 0-25 (for pN1 patients).

Recruiting
This is a multicenter, Phase 1b/2 trial in participants with estrogen receptor positive/human epidermal growth factor receptor 2 negative (ER+/HER2-) advanced/metastatic breast cancer. The phase 1b part of the trial will determine the recommended Phase 2 dose (RP2D) of elacestrant when administered in combination with alpelisib, everolimus, palbociclib, capivasertib, and ribociclib.

Ultra-hypofractionated Whole Breast Irradiation With Lumpectomy Cavity Boost for the Treatment of Stage I-III Breast Cancer
NCT06954831
Recruiting
This clinical trial tests how well ultra-hypofractionated (UF) whole breast irradiation (WBI) with lumpectomy cavity boost (CB) works in treating patients with stage I-III breast cancer. Breast conservation therapy (BCT) is the recommended treatment for patients with early stage breast cancer. BCT involves a lumpectomy followed by breast radiation. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Traditionally, WBI has been given o... Read More
