Clinical Trials for Breast Cancer

A Randomized Clinical Trial Comparing ctDNA-Directed Therapy Change With Standard of Care in Patients With Metastatic Triple 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.

HealthScout AI summary: Adults with newly diagnosed, measurable metastatic triple negative breast cancer (PD-L1 negative or ineligible for checkpoint inhibitors, no prior chemotherapy for metastatic disease) are randomized to receive standard chemotherapy with or without early therapy switch to sacituzumab govitecan (a TROP2-targeted antibody-drug conjugate delivering SN-38) based on ctDNA dynamics versus standard imaging assessment.

Phase IIa Study Assessing QBS72S For Treating Brain Metastases

Investigational drug late phase

The trial is testing an investigational drug and is at least phase 2, suggesting that the drug has shown promise in phase 1 studies and might have a high chance of working well compared to other investigational drugs.

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.

No known activity

No investigational drug(s) in this trial have shown anticancer activity yet in clinical trials

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.

HealthScout AI summary: This trial enrolls adults with relapsed, metastatic CNS disease (either brain metastases or leptomeningeal disease); Cohorts 1 and 2 include breast cancer patients after prior chemotherapy, while Cohort 3 includes patients with leptomeningeal disease from any solid tumor. All participants receive QBS72S, a LAT1-targeted chemotherapeutic agent designed to selectively kill tumor cells with high LAT1 expression, given as monthly IV infusions until progression.

ClinicalTrials.gov ID: NCT05305365

HealthScout AI summary: This trial enrolls adults with solid tumors (excluding CNS primaries and radiosensitive histologies) who have up to three contiguous vertebral levels of spinal metastases and minimal neurological deficit, treating them with spine-directed stereotactic body radiation therapy (SBRT) as definitive therapy instead of surgery. Prior intervention to the target site, unstable spines, and radiosensitive tumors are excluded.

A Phase 1a/1b Dose Escalation/Expansion Study of TTX-080, an HLA-G Antagonist, as Monotherapy and in Combination With Pembrolizumab, Cetuximab or FOLFIRI Plus Cetuximab in Patients With Advanced Solid Refractory/Resistant Malignancies

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.

HealthScout AI summary: This trial enrolls adults with advanced or metastatic solid tumors (including HNSCC, NSCLC, colorectal, TNBC, RCC, and acral melanoma) that are refractory or resistant to standard therapies, testing the investigational HLA-G antagonist monoclonal antibody TTX-080 alone or combined with pembrolizumab, cetuximab, or FOLFIRI plus cetuximab. Control arms include standard regimens for comparison in metastatic colorectal cancer.

ClinicalTrials.gov ID: NCT04485013

BettER: Biomarker Driven Early Therapeutic Selection in Patients With HR+ HER2- Metastatic or Unresectable 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.

HealthScout AI summary: This trial enrolls adults with HR+ HER2- metastatic or unresectable breast cancer starting first-line endocrine therapy plus a CDK4/6 inhibitor; patients are monitored using the DiviTum TKa assay, with early therapeutic switching to second-line treatment recommended for those whose thymidine kinase activity is not suppressed after two weeks. The study investigates whether this biomarker-guided approach can optimize progression-free survival and imaging schedules.

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

HealthScout AI summary: This trial enrolls postmenopausal women with advanced ER+ and/or HER2+ breast cancer who have progressed after standard therapies into multiple cohorts based on subtype, randomizing them to investigational combinations featuring the oral SERD giredestrant (estrogen receptor degrader), CDK7 inhibitor samuraciclib, pan-AKT inhibitor ipatasertib, PI3K inhibitor inavolisib, HER2-targeted agents, immune checkpoint blockade (atezolizumab), and/or standard partners. Patients must have good performance status and meet strict eligibility criteria, with adaptive assignment to novel regimens as new data emerge.
