Clinical Trials for Breast Cancer

Open-label Single-arm Phase 2 Trial of Trastuzumab Deruxtecan in Previously Treated HER2-Immunohistochemistry (IHC) 0 Advanced 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 unresectable or metastatic breast cancer strictly classified as HER2-IHC 0 (never HER2-positive or HER2-low), who have received 1–2 prior lines of systemic therapy and no prior anti-HER2 therapy, to evaluate trastuzumab deruxtecan (T-DXd), a HER2-targeted antibody-drug conjugate delivering a topoisomerase I inhibitor, given IV every 3 weeks.

ClinicalTrials.gov ID: NCT06750484

Phase 1 Study of Adoptive T Cell Therapy Following HER2-Pulsed Dendritic Cell Vaccine and Pepinemab / Trastuzumab in Patients With Metastatic HER2-Positive Breast Cancer

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 metastatic HER2-positive breast cancer who have progressed on trastuzumab and received up to three prior chemotherapy lines, and tests sequential treatment with HER2-pulsed dendritic cell vaccine, trastuzumab, and pepinemab (a SEMA4D inhibitor) followed by adoptive transfer of ex vivo expanded, HER2-specific CD4+ Th1 cells. Booster vaccines and continued trastuzumab/pepinemab maintenance follow adoptive cell infusion.

ClinicalTrials.gov ID: NCT05378464

A Pilot, Single-Arm, Phase II Trial of Tamoxifen Plus Pegylated Liposomal Doxorubicin 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.

TrialFetch AI summary: This trial enrolls adults with metastatic or inoperable locally advanced triple negative breast cancer who have received at least two prior therapies and have good performance status, treating them with a combination of daily oral tamoxifen and intravenous pegylated liposomal doxorubicin every 28 days. Pegylated liposomal doxorubicin acts as a DNA intercalator and topoisomerase II inhibitor, while tamoxifen is an estrogen receptor modulator; their combination is investigational in this setting.

Locally AblatiVe TherApy in OLigO-pRogressive SOlid TUmorS (VALOROUS)

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 various solid tumors (including breast, gynecologic, head and neck cancers, and sarcomas) who have oligo-progressive disease (≤5 progressing metastatic lesions) despite ongoing benefit from systemic therapy; patients continue their current systemic treatment and receive locally ablative therapy (via stereotactic ablative radiotherapy or image-guided ablation) to all progressing sites.

ClinicalTrials.gov ID: NCT06103669

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

Phase Ib Expansion Study of CX-5461 in Patients With Solid Tumours and BRCA2 and/or PALB2 Mutation

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 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.
