Descriptive Information
Brief Title Study of Effects of YisuiShengxueGranules on Thalassemia
Official Title A Double-blind, Placebo-controlled, Randomized, Parallel-group Study of the Safety and Effects of YisuiShengxueGranules on Thalassemia Presenting the Syndrome of Deficiency of Liver/Kidney-yin, and Asthenia of Essence/Blood.
Brief Summary The primary objectives of this study are to evaluate whether Yisui Shengxue Granules therapy can increase the hemoglobin level in peripheral blood and alleviate the symptoms, and at the same time, evaluate its safety in the treatment of Thalassemia with the syndrome of deficiency of liver-yin and kidney-yin, and asthenia of essence and blood.
Detailed Description

3. INVESTIGATION PLAN 3.1 Study Design and Plan This study is a double-blind, placebo-controlled, randomized Parallel-group trial. Guang'anmen Hospital is the sponsor and has designed the clinical trial protocol. No.303 Hospital of Chinese People's Liberation Army (PLA) is the collaborator, where the most patients come from.

3.2 Random Method Using the randomized block design,stratifying by α-Thalassemia and β-Thalassemia, the patients will be allocated randomly 1:1 to Yisui Shengxue Granules group or placebo group.

Statistic Analysis System (SAS, SAS institute, Cary, NC, USA) was used to produce 001~120 random code, matching 120 subjects who divided randomly 1:1 into Yisui Shengxue Granules group and placebo group.

3.3 Blinding Design 3.3.1 Packaging of the study drug and placebo: all drugs including medical emergency envelops must be repackaged and reallocated according to regulations of standard double-blind clinical trial.

3.3.2.Blinding The encoded data will be kept in Guang'anmen Hospital, China Academy of Chinese Medical Sciences.

When all patients fulfill the procedures of the trial, the data will be entered into electronic Case Report Forms (eCRFs) and locked, and then the blind will be disclosed.

If unmasking is necessary because of a serious, unexpected and related adverse event or if a medical emergency occurs which requires knowledge of the exact therapy, the investigator may contact the principal investigator or censor to determine whether the medical emergency envelop will be broken. The date and reason of the code breaking must be documented and signed and this information must be sent to the sponsor and collaborator. The patient should be withdrawn from Study Medication but be followed up according to the protocol.

If twenty percent medical emergency envelops are broken or blinding method is betrayed, this trial will be fail.

3.4 Sample Size Estimation A total of 120 patients will be required (α-Thalassemia: 80, β-Thalassemia: 40 ), assuming a relative risk of sample loss (no more than 20%) in the whole trial-- an accrual period of 3 months treatment and a minimum 3 months follow up. The numbers of patients in both study drug group and placebo group are equal.

4.6 Removal of Patients from Study 4.6.1 Investigators make the decision of patients' withdrawal.

Investigators will decide to withdraw the patients if they have following conditions in the middle of the trial:

  1. Upper respiratory tract infection with temperature higher than 38.5℃. This condition will lead to hemolysis aggravation and hemoglobin level decreasing, affecting the evaluation of therapeutic effects. The patients will be regarded as invalid cases once they withdraw from the trial and accept other therapy.
  2. Anemia complications or physiological changes make the patients being unsuitable to continue in this clinical study.
  3. Patients, with poor compliance, take the Study Medication less than 80% or more than 120%.
  4. Unblinding cases and unmasking cases because of medical emergency.
  5. Taking prohibited drugs.
  6. Refusing to take any Study Medication. 4.6.2 Patients make the decision of their withdrawal. In accordance with the World Medical Association Declaration of Helsinki (1996 version), as amended from time to time, all patients have the right to withdraw from the study at any time and for any reason, without prejudice to his or her future medical care by the physician or institution, and is not obliged to give his or her reasons for doing so. Without compromising the right of patients to withdraw from the trial, every effort will be made to understand and accommodate their concerns and avoid withdrawal wherever possible. If patients do not fulfill the therapy, tests, or follow-up for any reason, the patients will be dealt with as removal from the study.

4.6.3 The case report forms of withdrawal patients, for whatever reason, must be kept. The last test results will be dealt with as the terminal results to enter the full analysis set. If the significant effects are showed up in less than 3 moths, the patients will be considered as significant effective cases though they complete the trial in advance.

4.7 Termination Criteria Trial termination means the study may be terminated at any time if the study represents a serious medical risk to the patients.

  1. Serious safety risk.
  2. Gross error in the clinical trial protocol or major deviation appears during trial execution.
  3. Sponsor's request (reasons of finance, administration, etc.)

5.3 The Packaging Boxes and Preservation In a large packaging box, there will be three medium size packing boxes, containing 3 months dosage of Study Medication for one patient. The Study Medication can be either Yisui Shengxue Granules or placebo according to the random code, preserved by specially-assigned person and stored in dry environment at room temperature.

5.4 Drugs Assignment, Checking and Return Study Medication will be delivered to each clinical center according to the Study Medication code that randomly assigned to the clinical center, and be distributed to patients, who fulfill the inclusion criteria, in the order of drug code in 3 times. "Drug Used Report" should be filled in timely and kept by drug administrator.

Investigators should record the Study Medication quantity that patients received, took, and returned when they visit.

5.5 Drugs Blinding and Medical Emergency Envelope Study Medication blinding will be made by the corresponding department according to the randomization list. A medical emergency envelope, with detailed information of the medication, will be prepared for every randomization code and be kept in the principal investigator of each clinical center.

5.6 Precautions and Prohibited Drug Combination

  1. In this Trial, other drugs for β-Thalassemia are prohibited.
