Comparison of Interleukin-11 and rhTPO for Recurrent Colorectal Cancer Patients With Thrombocytopenia

January 28, 2019 updated by: Zhu Ji, Fudan University

A Randomized Phase II Study of Recombinant Human Thrombopoietin (Rh-TPO) and Recombinant Human Interleukin-11 (rhIL-11) for Recurrent Colorectal Cancer (CRC) Patients With Thrombocytopenia

This randomized controlled clinical phase II study was designed to compare the effect of rhTPO with rhIL-11 in improving thrombocytopenia in patients with recurrent colorectal cancer who underwent radiotherapy and with thrombocytopenia.

Detailed Description

Most patients with recurrent CRC have undergone a six-month postoperative adjuvant chemotherapy with oxaliplatin plus fluorouracil. Although the main dose-limiting side effect of oxaliplatin is neurotoxicity, with the widespread use of this drug, there are more and more reports that oxaliplatin is discontinued because of thrombocytopenia, which increases the risk of bleeding, rate of blood transfusion needs and length of stay. On the other hand, patients undergoing pelvic radiotherapy may also experience significant bone marrow suppression because flat bones such as the tibia may be exposed to high doses radiation. Low platelet counts is an urgent problem to be solved in order to give adequate quantitative radiotherapy. This randomized controlled clinical phase II study was designed to compare the effect of rhTPO with rhIL-11 in improving thrombocytopenia in patients with recurrent colorectal cancer who underwent radiotherapy and with thrombocytopenia, thus providing more evidence in clinical practice.

Description

Inclusion Criteria:

  • The primary tumor is colorectal cancer, histologically proved recurrence or metastasis disease, or pelvic relapse within 6 months after oxaliplatin-based adjuvant chemotherapy.
  • Not suitable for re-use of oxaliplatin and fluorouracil.
  • No medication history of irinotecan.
  • Lesions evaluable, and has indications for radiotherapy.
  • UGT1A1*28 gene phenotype is 6/6 or 6/7
  • Karnofsky physical condition score ≥ 70
  • Baseline platelet counts are 25-75×10^9/L, other bone marrow reserve and liver and kidney function meet the requirements of radiotherapy
  • Able to follow the program during the study period
  • Sign the informed consent

Exclusion Criteria:

  • Pregnant or breastfeeding women
  • Those with other history of malignant disease in the past 5 years, except for cured skin cancer and cervical carcinoma in situ
  • If there is an uncontrolled history of epilepsy, central nervous system disease or mental disorder, the investigator may determine that the clinical severity may hinder the signing of informed consent or affect the patient's oral medication compliance.
  • Clinically severe (ie, active) heart disease, such as symptomatic coronary heart disease, New York Heart Association (NYHA) class II or more severe congestive heart failure or severe arrhythmia requiring medication intervention (see appendix 12), or a history of myocardial infarction in the last 12 months
  • Organ transplantation requires immunosuppressive therapy
  • Severe uncontrolled recurrent infections, or other serious uncontrolled concomitant diseases
  • Subject blood routine and biochemical indicators do not meet the following criteria: hemoglobin ≥ 90g / L; absolute neutrophil count (ANC) ≥ 1.5 × 109 / L; Alanine transaminase (ALT), aspartate aminotransferase (AST) ≤ 2.5 times the upper limit of normal; alkaline phosphatase (ALP) ≤2.5 times the normal upper limit; serum total bilirubin <1.5 times the normal upper limit; serum creatinine <1 times the normal upper limit; serum albumin ≥ 30g / L
  • Anyone who is allergic to any research medication
