Terms in these criteria, in plain language(16)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

    Romiplostim N01 for Injection

    Drug: Romiplostim N01

Interventions

  • Romiplostim N01 for Injection: 3.0 µg/kg, QW. If the administration coincides with a chemotherapy day, the Romiplostim N01 for injection should be completed within 2 hours prior to chemotherapy. If no chemotherapy is scheduled on the planned dosing day, the injection timing is unrestricted. Thereafter, platelet counts should be monitored once or twice weekly. Subsequent dose adjustments follow the principle of guideline-based titration: when platelet count is \<50×10⁹/L, the dose is increased by 1-2 µg/kg per week; when platelet count is between 50×10⁹/L and 75×10⁹/L, the dose is increased by 1 µg/kg per week. Treatment should be discontinued if Romiplostim N01 for injection at 10 µg/kg administered weekly for 4 consecutive weeks fails to achieve a response. Non-response is defined as a platelet count ≤75×10⁹/L after 4 weeks of continuous administration, accompanied by an increase from baseline of ≤30×10⁹/L over the same period.

What researchers measure

Primary outcomes

  1. Proportion of patients achieving response

    Defined as platelet recovery over two consecutive cycles, with no dose modification (≥15% reduction, ≥4-day delay, or discontinuation) due to thrombocytopenia, and no rescue treatment.

    Time frame: up to the completion of two consecutive treatment cycles, an average of 6 weeks

Secondary outcomes

  1. Proportion of patients with platelet count <50×10⁹/L per cycle

    Proportion of patients with platelet count \<50×10⁹/L per cycle

    Time frame: until the end of each treatment cycle, an average of 3 weeks

  2. Minimum and maximum platelet counts

    To evaluate the minimum and maximum platelet counts throughout the entire treatment period.

    Time frame: through study completion, an average of 1year

  3. Number of symptomatic bleeding episodes during the treatment period

    Number of symptomatic bleeding episodes during the treatment period

    Time frame: through study completion, an average of 1year

  4. Number of participants with treatment-related adverse events as assessed by CTCAE v5.0

    Number of participants with treatment-related adverse events as assessed by CTCAE v5.0

    Time frame: through study completion, an average of 1year

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Aug 2026; primary completion for Apr 2028, 20 months later.

Of 44 non-industry phase 2 interventional studies under Thrombocytopenia, half reached primary completion within 63 months of starting (the median), counting those still running; a quarter within 33 and three quarters within 83. This study's planned 20 months is below that.

Counting every sponsor, half of 54 studies reached it within 36 months; a quarter within 28 and three quarters within 81.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
