Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) is an important means of curing a wide range of hematologic diseases, and good hematopoietic and immune reconstitution after transplantation is one of the most important factors determining the success of the transplantation.Persistent thrombocytopenia after Allo-HSCT is one of the common post-transplantation complications.This is an investigator-initiated, single-center, single-arm, Phase II clinical trial to evaluate the efficacy and safety of Romiplostim N01 for platelet recovery after UCBT in patients with hematologic tumors. The study was conducted in patients ≥18 years of age with a diagnosis of hematological neoplasia who underwent UCBT. Subjects will be screened and receive roprostin N01 from +1 to +28 days after UCBT after signing an informed consent form, and the study will focus on the cumulative PLT implantation rate at 28 days after transplantation as the primary efficacy measure. The study is planned to enroll 34 patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Drug: Romiplostim N01
Romiplostim N01 was administered subcutaneously once weekly from +1 day to +28 days after UCBT at a recommended starting dose of 5µg/Kg (maximum single dose not to exceed 250µg) for a total of 4 administrations, with the option of continuation of dosing/switching/discontinuing after +28 days, depending on the patient's platelet profile.

What is the study measuring?

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: 28 days
Platelet engraftment is defined as independence from platelet transfusion for at least 7 days with a platelet count of more than ≥20 × 10^9/L.
