Combining Surufatinib with Chemotherapy for Osteosarcoma Treatment

A Prospective, Multicenter, Non-randomized Controlled Clinical Study of Surufatinib Combined With Chemotherapy as Neoadjuvant Treatment in Patients With Osteosarcoma

PHASE2 · Second Affiliated Hospital, School of Medicine, Zhejiang University · NCT05926492

This study is testing if combining a new drug called surufatinib with chemotherapy can help people with osteosarcoma before surgery, compared to chemotherapy alone.

What this trial studies

This phase II clinical study investigates the effectiveness of surufatinib, a CSF-1R inhibitor, when combined with chemotherapy as a neoadjuvant treatment for osteosarcoma. The study aims to enroll 160 patients, dividing them into two groups: one receiving the combination treatment and the other receiving chemotherapy alone. The primary focus is on measuring the tumor necrosis rate after two cycles of treatment, with secondary outcomes including progression-free survival and safety assessments. This multicenter approach seeks to provide insights into the potential benefits of this novel treatment regimen.

Who should consider this trial

Good fit: Ideal candidates include patients aged 2 to 70 with a confirmed diagnosis of primary bone tumor and at least one measurable lesion.

Not a fit: Patients who have previously received any form of chemotherapy or targeted therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could improve tumor response rates and overall outcomes for osteosarcoma patients.

How similar studies have performed: While the combination of targeted therapies with chemotherapy is a growing area of interest, this specific approach with surufatinib in osteosarcoma is novel and has not been extensively tested in prior studies.

4. International Standardized Ratio (INR)\> 1.5 or partially activated prothrombin time (APTT) \> 1.5×ULN;
5. The investigator identified clinically significant electrolyte abnormalities;
6. The patient currently has hypertension that cannot be controlled by drugs, as follows: systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg;
7. Unsatisfactory blood glucose control (FBG \> 10 mmol/L);
8. The patient has any current disease or condition that affects the absorption of the drug, or the patient cannot take surufatinib orally;
9. The patient currently has gastrointestinal diseases such as active gastric and duodenal ulcers, ulcerative colitis, or active bleeding from unresected tumors, or other conditions determined by researchers that may cause gastrointestinal bleeding or perforation;
10. Patients with evidence or history of significant bleeding tendency within 3 months prior to enrollment (bleeding \>30 mL within 3 months , hematemesis, stool, stool blood), hemoptysis ( \> 5 mL of fresh blood within 4 weeks) or had a thromboembolic event (including stroke events and/or transient ischemic attacks) within 12 months;
11. Clinically significant cardiovascular disease, including but not limited to the following: acute myocardial infarction, severe/unstable angina pectoris, or coronary artery bypass grafting within 6 months prior to enrollment; New York Heart Association (NYHA) Grades for Congestive Heart Failure was \> level 2; Ventricular arrhythmias requiring medical treatment; LVEF (Left ventricular Ejection Fraction) \< 50%;
12. Have had other malignancies within the past 5 years, except basal cell or squamous cell carcinoma of the skin after radical surgery, or carcinoma in situ of the cervix;
13. Active or uncontrolled severe infection; 1) Known human immunodeficiency virus (HIV) infection; 2) Known history of clinically significant liver disease, including viral hepatitis \[active HBV infection, i.e., HBV DNA positive (\> 1×104 copies /mL or \> 2000 IU/ml) must be excluded for known hepatitis B virus (HBV) carriers; 3) Known hepatitis C virus infection (HCV) and HCV RNA positive (\> 1×103 copies /mL), or other hepatitis, cirrhosis;
