About this study
Official title: A Prospective Randomized Phase Ⅱ Study of Trilaciclib Combing Chemotherapy in the Neoadjuvant Treatment of Osteosarcoma
To evaluate the clinical application value in bone marrow protection of Trilaciclib in the neoadjuvant treatment of stage II/III classic osteosarcoma in combination with pirarubicin and lobaplatin.
Read the detailed description
Classic osteosarcoma is the most common primary bone malignancy. At present, osteosarcoma is usually treated with preoperative chemotherapy, surgical operation and postoperative chemotherapy. Treatment with preoperative chemotherapy is also known as neoadjuvant chemotherapy. Neoadjuvant chemotherapy has brought benefits to patients, but safety concerns are inevitable. Myelosuppression is a major factor affecting the compliance of patients treated by chemotherapy. Patients with chemotherapy-induced myelosuppression(CIM) have higher rates of infection, sepsis, bleeding, and fatigue, resulting in hospitalization, hematopoietic growth factor support, blood transfusions (red blood cells and/or platelets) and even death. In addition, CIM often leads to dose reduction and delayed administration, which limits the therapeutic dose intensity and therefore affects the anti-tumor efficacy of chemotherapy.
Currently, there are no approved treatments in osteosarcoma to prevent chemotherapy-induced cell damage. Although some treatments may help to address CIM when it occurs such as blood transfusions and growth factors, these treatments are pedigree specific, being used after hematopoietic stem progenitor cells damage and could bring additional toxicity.
Trilaciclib is a highly effective, selective and temporarily reversible inhibitor of CDK4/6. The proliferation of bone marrow hematopoietic stem cells depends on CDK4/6 activity. Bone marrow hematopoietic stem cells are blocked in the G1 phase of the cell cycle after exposure to Trilaciclib before chemotherapy is given.
Therefore, this study is conducted to evaluate the clinical application value in bone marrow protection of Trilaciclib in the neoadjuvant treatment of stage II/III classic osteosarcoma in combination with pirarubicin and lobaplatin.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Trilaciclib, Pirarubicin and Lobaplatin in people with Osteosarcoma, run by Peking University People's Hospital 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 4 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: looking for participants now, as of the sponsor's last update on 3 Dec 2024. 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. Some participants in this study may receive a placebo. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of grade 3/4 neutropenia (time frame: up to 30 days). 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 3 Dec 2024; AzTrials last refreshed its copy on 7 Nov 2026.
