  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Age ≥15 years, regardless of sex (subjects ≥18 years old will be enrolled first; enrollment of subjects aged 15-18 years will commence after sufficient PK/PD data are obtained).

  • Absolute neutrophil count (ANC) <0.5×10⁹/L
  • Platelet count (PLT) <20×10⁹/L
  • Absolute reticulocyte count (RET) <60×10⁹/L The diagnostic criterion for VSAA is: meeting the SAA criteria + ANC <0.2×10⁹/L.
  • Written informed consent

  • History and/or concomitant presence of other primary or secondary bone marrow failure (BMF) syndromes, such as:
  • ①Primary: Fanconi anemia, dyskeratosis congenita, congenital amegakaryocytic thrombocytopenia or Shwachman-Diamond syndrome, symptomatic paroxysmal nocturnal hemoglobinuria (PNH), myelodysplastic syndromes (MDS), clonal cytopenia of undetermined significance (CCUS), antibody-mediated BMF, idiopathic cytopenia of undetermined significance (ICUS), etc.

  • Participation in another clinical trial with investigational drugs or medical devices within 30 days prior to the first dose or within 5 half-lives of the investigational product (whichever is longer).
Show all 18Show fewer
  • Previous use of any of the following agents prior to the first dose:
  • ATG/ALG
  • Alemtuzumab
  • Mycophenolate mofetil ④Sirolimus
  • Tacrolimus ⑥High-dose cyclophosphamide (≥45 mg/kg/day)
  • Cumulative cyclosporine A (CsA) therapy exceeding 4 weeks prior to the first dose. If cumulative use is ≤4 weeks, a washout period of >14 days prior to the first dose is required.
  • Cumulative use of thrombopoietin receptor agonists (TPO-RAs) for >14 days prior to the first dose, or cumulative use ≤14 days with a washout period of <14 days, including:
  • Romiplostim / Nplate® (romiplostim)
  • Eltrombopag ③Hetrombopag ④Recombinant human thrombopoietin, etc.
  • Previous history of hematopoietic stem cell transplantation.
  • Uncontrolled bleeding and/or infection after standard treatment prior to the first dose [defined as persistent signs/symptoms related to infection without improvement despite appropriate antibiotic and/or other therapy], or requiring intravenous (IV) antibiotic administration.

About this study

Official title: A Randomized, Controlled, Multicenter, Double-blind Phase III Study Evaluating the Efficacy and Safety of Romiplostim N01 Combined With Standard Immunosuppressive Therapy (IST) Versus Placebo Combined With IST in Treatment-naïve Subjects With Severe Aplastic Anemia

This is a randomized, double-blind, multicenter trial designed to evaluate treatment with romiplostim N01+ IST compared with placebo + IST in the participants with treatment-naïve severe aplastic anemia.

Being tested
Romiplostim N01, Cyclosporine A (CsA), pALG/ rATG, Placebo

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Romiplostim N01Drug

    Starting from Day 1 of Week 1, administer the initial dose of romiplostim N01: 10 μg/kg. Platelet count (PLT) must be monitored weekly. The dose should be adjusted based on platelet values (adjusted by 5 μg/kg per change, see the table below for specific rules), administered once weekly, with a maximum dose of 20 μg/kg.

  • Cyclosporine A (CsA)Drug

    Initiate at a dose of 5 mg/kg/day, administered orally in two divided doses (recommended at 12-hour intervals). The dose may be adjusted between 3 and 5 mg/kg/day based on the subject's tolerance.

  • pALG/ rATGDrug

    25 mg/kg/day on Days 1 through 5 of Week 1.

  • PlaceboDrug

    Starting from Day 1 of Week 1, administer the initial dose of placebo: 10 μg/kg. Platelet count (PLT) must be monitored weekly. The dose should be adjusted based on platelet values (adjusted by 5 μg/kg per change, see the table below for specific rules), administered once weekly, with a maximum dose of 20 μg/kg.

  • Cyclosporine A (CsA)Drug

    Initiate at a dose of 5 mg/kg/day, administered orally in two divided doses (recommended at 12-hour intervals). The dose may be adjusted between 3 and 5 mg/kg/day based on the subject's tolerance.

  • pALG/ rATGDrug

    25 mg/kg/day on Days 1 through 5 of Week 1.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Complete Response (CR) rate at the 6-month time point of treatment.

    Proportion of subjects achieving hematopoietic complete response at the 6-month.

    Hematopoietic complete response is defined as: hemoglobin ≥10 g/dL, absolute neutrophil count ≥1×10⁹/L, and platelet count ≥100×10⁹/L.

    Measured: During 6 months of therapy

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Romiplostim N01, Cyclosporine A (CsA) and pALG/ rATG in people with Treatment-naïve Severe Aplastic Anemia, run by Qilu Pharmaceutical Co., Ltd..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 15 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact jun shi, Professor (022-23608326, shijun@ihcams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete Response (CR) rate at the 6-month time point of treatment. (time frame: During 6 months of therapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jan 2026; AzTrials last refreshed its copy on 26 Oct 2026.
