      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: This study is a randomized controlled clinical trial in which all patients are examined in two groups, which we represent with two symbols A and B. Group A will receive L-glutamine and hydroxyurea combination therapy in the intervention (intervention group) and group B will receive hydroxyurea treatment alone (control group). Participants in the study will be randomly divided into two groups A and B equal to .... individual. In order to randomly assign individuals to two equal groups to receive the intervention, the Permuted Block Randomization method with a block size of 6 has been used. The block randomization scheme was created using the free Randomization.com website (http://randomization.com). From the order of the Permuted Block Randomization table, the allocator and evaluator should not be aware of the type of intervention being performed on the individual and the size of the block. Thus, it can be said that the data allocation will remain hidden until the end of the study. Thus, each participant will be assigned to intervention or control groups and will enter the study.

A_____________________________________, Blinding description: From the order of the Permuted Block Randomizotion table, the allocator and evaluator should not be aware of the type of intervention being performed on the individual and the size of the block. Thus, it can be said that the data allocation will remain hidden until the end of the study. In this way, each participant will be assigned to intervention or control groups and will be included in the study. Pain Crisis Judgment and Laboratory Tests: All pain crises reported in the case report forms will be recorded by the researchers. An independent judging panel consisting of two hematologists-oncologists who are unaware of the assignment of the trial team will evaluate each episode to determine whether the event meets the definition of a pain crisis for performance evaluation.</study_design>

      <i_freetext>Intervention 1: Intervention group: Intervention group: The allocation of two randomized block blinds is encoded in numbered envelopes and is prepared according to the number of samples and will be provided to the patient's attending physician. Therefore, eligible patients will be randomly divided into a 1: 1 ratio for L-glutamine and hydroxyurea combination therapy or hydroxyurea alone, with randomized block allocation. The planned treatment period will be 6 months, during which patients, in addition to consuming hydroxyurea, take L-glutamine powder orally twice a day at a dose of approximately 0.3 g / kg body weight per dose (10 g, 20 g). Grams or 30 grams [maximum dose] per day). The contents of the package will be mixed with an unheated drink or food and consumed immediately. Patients will be contacted by telephone each week between monthly visits to encourage adherence. The validity of the test group assignment and the correct supply of L-glutamine or placebo for each patient will be verified by an independent research drug service. Patients can receive blood transfusions and other necessary clinical treatments if needed. Intervention 2: Control group: The allocation of two randomized block blinds is encoded in numbered envelopes and is prepared according to the number of samples and will be provided to the patient's attending physician. Therefore, eligible patients will be randomly divided into a 1: 1 ratio for L-glutamine and hydroxyurea combination therapy or hydroxyurea alone, with randomized block allocation. The planned treatment period will be 6 months, during which the control group will receive placebo powder (100% maltodextrin) orally twice a day. Experimental drug and placebo in individual packages and visually identical contain 5 grams of white powder without taste is provided, and all packages will be returned by patients to assess compliance. The contents of the package will be mixed with an unheated drink or food and consumed immediately. Patients will be contacted by telephone each week between monthly visits to encourage adherence. The validity of the test group assignment and the correct supply of L-glutamine or placebo for each patient will be verified by an independent research drug service.
