About this study

Official title: Trilaciclib in Combination With Anti-PD-1 Antibody and Chemotherapy in the Treatment of Locally Advanced Triple-negative Breast Cancer: A Prospective, Single-arm, Multicenter Phase II Clinical Study

Trilaciclib is a highly potent, selective, and reversible CDK4/6 inhibitor that protects bone marrow by protecting hematopoietic stem cells and progenitor cells (HSPCs) during systemic chemotherapy. The proliferation and differentiation of HSPCs are highly dependent on the CDK4/6 signaling pathway, and when exposed to the appropriate dose of treacilil, they will be blocked in the G1 phase of the cell cycle, thus avoiding the killing of cell cycle-specific chemotherapy drugs. This is an open, single-arm, multicenter Phase II clinical study. Newly diagnosed TNBC patients with T1c N1-2 or T2-4 N0-2 will be screened according to the inclusion criteria. Fifty patients meeting the inclusion criteria will sign informed consent letters and receive neoadjuvant therapy with Trilaciclib + anti-PD-1 antibody + Paclitaxel-albumin + carboplatin. To evaluate the synergistic effect of Trilaciclib on bone marrow protection and anti-tumor therapy.

Read the detailed description

Myelosuppression is the cause of many cancer chemotherapy-related adverse events, such as infections, sepsis, bleeding, and fatigue, resulting in delayed hospital stays or the need for treatment with hematopoietic growth factors, blood transfusions, and so on. In addition, myelosuppression usually leads to a lower dose or more extended interval of chemotherapy, which reduces the intensity of chemotherapy and affects the benefit of chemotherapy for patients.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Trilaciclib in people with Triple Negative Breast Cancer, run by QIAO LI at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Binghe Xu (86-10-87788495, xubinghe@medmail.com.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of ≥ grade 3 neutropenia during chemotherapy (time frame: At the end of Cycle 1 (each cycle is 21days)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 May 2025; AzTrials last refreshed its copy on 8 Nov 2026.
