Apatinib Mesylate Combined With IT Regimen for the Treatment of Recurrent or Refractory Pediatric Neuroblastoma: A Single-arm, Phase I/II，Multi-center, Clinical Study.

Recruiting now · Phase 1/Phase 2

Conditions studied: Neuroblastoma

In brief

The survival rate of recurrent and refractory pediatric neuroblastoma is low and the prognosis is poor. Apatinib mesylate is a highly selective small-molecule vasoendothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor. Apatinib mesylate has been shown to be safe and effective in recurrent or refractory pediatric neuroblastoma in Sun Yat-sen University Cancer Center. Apatinib mesylate combined with IT regimen is expected to further improve the efficacy and survival rate of recurrent or refractory pediatric neuroblastoma.

Who can join

Age: 5 and older, up to 18. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 5years ≤ age ≤18 years old, regardless of gender;;
• ECOG performance status (PS) score: 0～1;
• The expected survival time is more than 12 weeks;
• Children with neuroblastoma confirmed by histopathology;
• Patients who have progressed, recurrent or refractory disease after first-line treatment (failure to obtain complete or partial remission after recent treatment);
• With measurable lesions (according to the RECIST 1.1 standard, the CT scan of tumor lesions has a long diameter ≥10mm, and the CT scan of lymph node lesions has a short diameter ≥15mm. The measurable lesions have not been treated with radiotherapy or cryotherapy);
• The patients must recover from the acute toxic effects of all previous anticancer chemotherapy fully;
• Myelosuppressive chemotherapy: at least 21 days after the last myelosuppressive chemotherapy (If nitrosourea was used in the early stage, the interval time is 42 days);
• Experimental drugs or anti-cancer therapies other than chemotherapy: It is not allowed to use other experimental drugs within 28 days before the planned start of use, and it is necessary to fully recover from the clinically significant toxicity of the therapy;
• Hematopoietic growth factors: at least 14 days after the last administration of long-acting growth factors or 3 days after the last administration of short-acting growth factors;
• 11. Immunotherapy: At least 42 days after completing any type of immunotherapy (except steroids), such as immune checkpoint inhibitors and tumor vaccines;
• 12. X-ray therapy (XRT): at least 14 days after local palliative XRT (small-scale mouth); if it is another substantial bone marrow (BM) irradiation, including pre-radio-iodinated metaiodobenformin (131I-MIBG) treatment, the interval time must end at least 42 days;
• Stem cell infusion without total body irradiation (TBI): there is no evidence of active graft-versus-host disease, at least 56 days after transplantation or stem cell infusion;
• Laboratory inspections during the screening period should meet the following conditions: The absolute value of neutrophils (ANC) ≥1.5×109/L (if the bone marrow is invaded, then ANC≥1.0×109/L) Platelet (PLT) ≥75×109/L (if bone marrow invades, then PLT ≥50×109/L) Bilirubin ≤1.5 times ULN Creatinine ≤ 1.5 times ULN (calculated according to the standard Cockcroft-Gault formula) ALT/AST≤3 times ULN (if there is liver metastasis, it can be relaxed to 5 times ULN);
• During the study period, patients should be able to comply with outpatient treatment, laboratory monitoring, and necessary clinical visits;
• Parents/guardians of a child or young patients have the ability to understand, agree, and sign the research informed consent form (ICF) and applicable child consent form before initiating any program related procedures; Subjects can express consent (where applicable) with the consent of the parent/guardian.

You may not qualify if…

• Symptomatic brain metastases (patients with brain metastases who have completed treatment 21 days before enrollment and have stable symptoms can be enrolled, but they need to be evaluated by cranial MRI, CT, or venography to confirm that they have no symptoms of cerebral hemorrhage);
• Imaging (CT or MRI) shows that the tumor focus is ≤ 5 mm from large blood vessels, or there is a tumor that invades local large blood vessels;
• Patients with hypertension who are using two or more antihypertensive drugs in combination therapy;
• Patients who suffer from the following cardiovascular diseases: Myocardial ischemia or myocardial infarction above grade II, poorly controlled arrhythmia (including QTc interval ≥450 ms for males and ≥470 ms for females); according to NYHA standards, grade III to IV cardiac insufficiency, or the heart color Doppler ultrasound examination showed that the left ventricular ejection fraction (LVEF) <50%;
• Patients with a history of interstitial pulmonary disease or who also suffer from the interstitial pulmonary disease;
• Abnormal coagulation function (INR>1.5 or prothrombin time (PT)>ULN+4 seconds or APTT>1.5 ULN), have a bleeding tendency or are receiving thrombolytic or anticoagulant therapy;
• The daily volume of hemoptysis reached two teaspoons or more before enrollment;
• Patients who have had clinically significant bleeding symptoms or a clear bleeding tendency within 3 months before enrollment, such as gastrointestinal bleeding, hemorrhagic hemorrhoids, hemorrhagic gastric ulcer, fecal occult blood++ and above at baseline, or vascular
• Arterial/venous thrombosis events that occurred in the 12 months before enrollment, such as cerebrovascular accidents (including temporary ischemic attacks, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism;

• Long-term unhealed wounds or fractures (pathological fractures caused by tumors are not counted);
• Patients who received major surgery or suffered severe traumatic injury, fracture, or ulcer within 4 weeks of enrollment;
• some factors significantly affect the absorption of oral drugs, such as inability to swallow, chronic diarrhea, and intestinal obstruction;
• Abdominal fistula, gastrointestinal perforation, or abdominal abscess occurred within 6 months before enrollment;
• Urine routine test showed urine protein ≥ ++, and confirmed 24-hour urine protein ≥ 1.0 g; Notes: Asymptomatic serous effusions can be included in the group, and symptomatic serous effusions have been actively treated symptomatically (anti-cancer drugs cannot be used for the treatment of serious effusions), and patients who are judged by the investigator can be included in the group，allow to join the group.
