Clinical Trials for Breast Cancer

A Phase I Study of Concurrent Abemaciclib and Radiation Therapy (RT) for Patients With Metastatic Hormone Receptor Positive (HR+), HER2 Negative (HER2-) Breast Cancer

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

TrialFetch AI summary: This trial enrolls adults with metastatic hormone receptor-positive, HER2-negative breast cancer who require radiation for bone metastasis, including those with prior CDK4/6 inhibitor exposure. Patients receive focal radiation therapy combined with abemaciclib, an oral CDK4/6 inhibitor that blocks cell cycle progression, with abemaciclib dose escalation to determine safety and tolerability.

ClinicalTrials.gov ID: NCT06678269

A Study to Evaluate the Safety and Tolerability of the Covalent Phosphoinositide-3-Kinase (PI3K)-Alpha Inhibitor, TOS-358, in Adult Subjects With Select Solid Tumors

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: This trial enrolls adults with advanced or metastatic HR+/HER2- breast cancer, squamous head and neck, urothelial, or endometrial cancers harboring PIK3CA mutations or amplifications, who have not previously received PI3K, AKT, or mTOR inhibitors. Patients receive TOS-358, a first-in-class, covalent, and selective PI3Kα inhibitor, administered orally as a single agent.

ClinicalTrials.gov ID: NCT05683418

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: This trial enrolls adults with advanced pancreatic, prostate, breast, or ovarian cancers harboring pathogenic or likely pathogenic germline BRCA2 and/or PALB2 mutations (with an exploratory cohort for other HRD-associated ovarian/fallopian/peritoneal cancers), treating them with intravenous CX-5461, a G-quadruplex DNA stabilizer that selectively targets homologous recombination–deficient tumor cells. Prior PARP inhibitor and systemic therapies are allowed, and patients must have measurable disease and ECOG ≤2.

SERIES: SEquencing Sacituzumab Govitecan AfteR T-DXd In ER+/HER2 LOW MetaStatic Breast Cancer

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

TrialFetch AI summary: This trial enrolls adults with metastatic, hormone receptor positive (HR+)/HER2-low breast cancer who are endocrine-refractory and have progressed after prior trastuzumab deruxtecan (T-DXd); all participants receive sacituzumab govitecan, an antibody-drug conjugate targeting Trop-2 and delivering SN-38, to assess its efficacy in this setting.

ClinicalTrials.gov ID: NCT06263543

A Phase II Trial to Evaluate Functional Imaging in Prediction of Response to Abemaciclib for Advanced Hormone Receptor-Positive, HER2-Negative Breast Cancer

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

TrialFetch AI summary: This trial enrolls adults with metastatic or locally advanced unresectable, ER-positive, HER2-negative breast cancer (no prior abemaciclib) to receive abemaciclib (a selective CDK4/6 inhibitor) plus standard endocrine therapy, with pre-treatment functional imaging to assess predictive biomarkers of response. Both men and premenopausal women are eligible with appropriate endocrine management.

ClinicalTrials.gov ID: NCT06179303

Pilot Feasibility Study of Tumor Treating Fields in Treatment of Leptomeningeal Metastases From Breast Carcinoma Involving the Spine

Moderate burden on patient

The trial has a moderate burden on patients. An example would be a trial testing an IV drug, with scans every 8 weeks which would be more frequent than standard of care.

TrialFetch AI summary: Adults with metastatic breast cancer and MRI/CSF-confirmed spinal leptomeningeal metastases receive tumor treating fields (TTF) therapy using the portable NovoTTF-200T device, a noninvasive treatment that disrupts tumor cell division via alternating electric fields. No concurrent high-dose intrathecal or CNS-directed cytotoxic therapy is allowed.

ClinicalTrials.gov ID: NCT05746325

A First in Human Phase I Trial of Binary Oncolytic Adenovirus in Combination With HER2-Specific Autologous CAR T Cells in Patients With Advanced HER2 Positive Solid Tumors

Active drug

Investigational drug(s) in this trial have shown anticancer activity in clinical trials

High burden on patient

The trial has a high burden on patients. An example would be a phase 1 trial with extra tumor biopsies and frequent pharmacokinetic blood draws.

Started >3 years ago

The trial was activated more than 3 years ago. This is not always bad but can indicate that the trial has less current treatments, or has had trouble getting enough patients to enroll due to other issues.

TrialFetch AI summary: Eligible adult patients have advanced, refractory HER2-positive solid tumors with at least one injectable lesion. The trial evaluates safety and preliminary efficacy of intratumoral CAdVEC, an oncolytic adenovirus expressing IL-12 and a PD-L1 blocker, alone or in combination with intravenous HER2-specific autologous CAR T cells at higher dose levels.
