Objectives: * Determine the corrected count increment of autologous transfused platelets that had been stored by cryopreservation with ThromboSol. * Determine the ability of autologous platelets that had been stored by cryopreservation with ThromboSol to correct thrombocytopenia. Platelets are an important component of blood. Transfusions with platelets help to control bleeding in thrombocytopenic patients. Using the standard blood banking procedures, platelets can only be stored for up to 5 days. This is to help decrease the risk of contamination with bacteria. Currently, it is not possible to use cryopreserved (frozen) platelets because the platelets are damaged during the freezing process. Therefore, long-term banking of platelets or autologous donation (storing your own platelets to be given back to you at a later time) has not been possible. ThromboSol is a new solution that was designed to allow platelets to be frozen without damaging them. The use of ThromboSol may allow for long-term banking of platelets and/or autologous donations. During a period of cancer remission and when you have enough platelets in your blood, you will undergo an apheresis procedure to collect platelets. This procedure is similar to donating plasma to a blood bank. You will have up to 6 apheresis procedures (on different days) to collect up to 6 units of autologous platelets that can be transfused back to you. The platelets that are collected will be frozen with ThromboSol and stored so that they may be given back to you if your platelet count drops below a certain level. The frozen platelets can be stored for up to 18 months. When your platelet count drops below a certain level, you will be scheduled to have a platelet transfusion as part of your standard care. Before the transfusion you will have blood drawn (around 1-2 teaspoons) to check on the number of platelets in your blood. You will then be randomly assigned (as in the toss of a coin) to either receive the standard platelet transfusion or a ThromboSol-preserved autologous platelet transfusion. After the transfusion, you will have additional blood drawn (around 1-2 teaspoons) to check on the number of platelets in your blood. These procedures will be repeated each time you require a platelet transfusion. However, you will not be randomly assigned again. Each time you receive an additional platelet transfusion, you will be assigned the group different from the one before. The type of transfusions will be alternated. For instance, if you were randomly assigned to receive the frozen platelets for your first transfusion, you will receive the standard transfusion next, then back to the frozen for the third transfusion. If you develop side effects to the ThromboSol-preserved autologous platelet transfusion or the number of platelets in your blood does not increase after an infusion with the preserved platelets, you will be taken off the study and given a standard platelet transfusion. This is an investigational study. Up to 54 participants will take part in this study. All will be enrolled at UTMDACC.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
4 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants receive different treatments one after the other, switching from one to another during the study. This helps researchers understand how individuals respond to multiple treatments.

Other Ways to Assign Treatments
Single-group assignment: Everyone gets the same treatment.
Parallel assignment: Participants are split into separate groups, each receiving a different treatment.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Criteria
1 inclusion criteria required to participate
) 1.- Patients in remission with ALL, CLL, AML, CML, MDS will be allowed to participate in this program if their platelet count is >150K, and the hemoglobin level is at least 8.0g/dl. The patient will receive their autologous platelets cryopreserved in ThromboSol or the fresh random platelets (FRP) whenever the need for such transfusions is determined to be clinically indicated by their physician(s)
1 exclusion criteria prevent from participating
) Patients with detectable circulating malignant cells or ongoing marrow involvement by the tumor will not be eligible

This study does not include a placebo group 

Treatment Groups
Group I
Experimental
ThromboSol-preserved autologous platelet transfusion or Standard platelet transfusion. All patients receive both platelets frozen with Thrombosol and fresh random platelets. The order in which patients receive these two types of platelets randomized in a crossover design. Patients randomly assigned to receive either the sequence FRP then Thrombosol or Thrombosol then FRP. The randomization will occur after second cycle of chemotherapy, since all patients will receive FRP with the first cycle.
