What Do the Terms in Chinese Clinical Trial Documents Mean?
A Chinese clinical trial document set contains the registration record, the recruitment notice, the informed consent form, the inclusion and exclusion criteria, and the study status. Each of these has its own terminology. Misreading an eligibility criterion, a consent clause, or a study status can change what you think you are agreeing to — or whether you are eligible at all.
Quick Answer
A Chinese clinical trial document set typically has six key parts: registration (注册, zhù cè), recruitment notice (招募, zhāo mù), inclusion criteria (入选标准, rù xuǎn biāo zhǔn), exclusion criteria (排除标准, pái chú biāo zhǔn), informed consent (知情同意, zhī qíng tóng yì), and study status (研究状态, yán jiū zhuàng tài). The highest-risk terms are the eligibility criteria (a single criterion can determine whether you qualify) and the informed consent clauses (which describe risks, benefits, and alternatives). A clinical trial document is a legal and clinical document, not a patient-facing explanation.
"If a trial is recruiting, I can join." — No. A recruiting trial still has inclusion and exclusion criteria. Meeting some criteria does not mean meeting all of them. A single exclusion criterion can make you ineligible, even if everything else fits. The eligibility criteria are not a formality — they are the trial's definition of who can safely participate.
Who This Page Is NOT For
This page is not a tool to determine your eligibility for any trial, and it is not a substitute for the explanation given by the trial team. It is for patients and families who have received Chinese clinical trial documents and want to understand their structure and terminology — so they can ask better questions of the trial team and their treating oncologist. Only the trial team, with the full protocol, can determine eligibility for a specific trial.
The Six Parts of a Chinese Clinical Trial Document Set
Most Chinese clinical trial document sets follow a standard structure. Knowing the parts helps you find the information you need — and helps you notice what is missing.
1. 注册 — Registration
The trial's registration record, usually in a public registry (for example, ChiCTR or ClinicalTrials.gov).
- Registration number
- Sponsor and institution
- Trial phase and design
2. 招募 — Recruitment notice
The public notice describing the trial and inviting participation.
- Brief title and summary
- Condition and intervention
- Contact information
3. 入选标准 — Inclusion criteria
The conditions a participant must meet to be eligible.
- Cancer type and stage
- Prior treatments required
- Performance status and organ function
4. 排除标准 — Exclusion criteria
The conditions that make a participant ineligible, even if they meet the inclusion criteria.
- Other active cancers
- Specific organ dysfunction
- Active infection or autoimmune disease
5. 知情同意 — Informed consent
The document describing the trial's purpose, procedures, risks, benefits, alternatives, and the participant's rights.
- Purpose and procedures
- Risks and benefits
- Alternatives and rights
6. 研究状态 — Study status
The current status of the trial (for example, recruiting, active, completed).
- 招募中 (recruiting)
- 进行中 (ongoing)
- 已完成 (completed)
- 已终止 (terminated)
Terms Most Often Misread
| Chinese term | Pinyin | Approximate English | Why it is easy to misread |
|---|---|---|---|
| 入选标准 | rù xuǎn biāo zhǔn | Inclusion criteria | The conditions you must meet. Missing a single inclusion criterion can make you ineligible. |
| 排除标准 | pái chú biāo zhǔn | Exclusion criteria | The conditions that make you ineligible even if you meet the inclusion criteria. Meeting inclusion does not override exclusion. |
| 知情同意 | zhī qíng tóng yì | Informed consent | The document you sign before participating. It describes risks, benefits, and alternatives — it is not a contract you can simply sign without understanding. |
| 随机分组 | suí jī fēn zǔ | Randomization | Means you may be assigned to one of two or more groups by chance, not by your choice or your doctor's choice. |
| 双盲 | shuāng máng | Double-blind | Neither you nor your doctor knows which treatment you are receiving. This is a design feature, not a sign of distrust. |
| 对照组 | duì zhào zǔ | Control group | The group receiving the standard treatment (or placebo). Being in the control group does not mean receiving "no treatment." |
| 不良事件 | bù liáng shì jiàn | Adverse event | Any unwanted medical occurrence during the trial, whether or not it is caused by the treatment. Reporting an adverse event does not mean the treatment caused it. |
| 方案偏离 | fāng àn piān lí | Protocol deviation | Any departure from the trial protocol. It does not automatically mean you are removed from the trial, but it must be documented. |
| 招募中 | zhāo mù zhōng | Recruiting | Means the trial is currently enrolling. It does not mean you are eligible, and it does not guarantee a slot. |
| 已终止 | yǐ zhōng zhǐ | Terminated | Means the trial has stopped. It does not by itself tell you why, and it does not by itself mean the treatment failed. |
A Fictional Example: Reading the Eligibility Section
The example below is fictional. It is used only to show how eligibility criteria appear in a clinical trial document. It is not derived from any real trial or patient.
How to read this example: The inclusion criteria list what you must meet to be eligible — age, diagnosis, prior treatments, and performance status. The exclusion criteria list what makes you ineligible even if you meet the inclusion criteria — active CNS involvement, prior CAR-T, active hepatitis, or severe cardiac dysfunction. The study status says "recruiting," but that does not mean you are eligible. You must meet all inclusion criteria and none of the exclusion criteria. A single exclusion criterion (for example, prior CAR-T) can make you ineligible even if everything else fits. Only the trial team can confirm eligibility.
Questions to Bring to the Trial Team and Your Oncologist
These questions are educational. They are not an assessment of your eligibility. Review the answers with the trial team and your licensed oncologist.
Do I meet every inclusion criterion, and do I meet any exclusion criterion?
Ask the trial team to review each criterion with you in the context of your case.
Is the trial randomized, and is it double-blind?
If so, ask what that means for your treatment — you may not be able to choose your group.
What are the risks, benefits, and alternatives described in the informed consent form?
Ask the trial team to walk you through each section, and ask what the standard treatment would be if you do not join the trial.
What is the current status of the trial at this site?
Ask whether the trial is currently recruiting at the site where you would be treated, not just in the registry.
What happens if I experience an adverse event — who do I contact, and how is it managed?
Ask for the specific contact and the management plan, before you sign the consent form.
Can I withdraw from the trial at any time, and what happens to my data if I do?
The informed consent form should describe withdrawal procedures. Ask the trial team to explain them.

Frequently Asked Questions
If a trial is "recruiting," can I join?
Not necessarily. "Recruiting" means the trial is currently enrolling, but you must still meet all inclusion criteria and none of the exclusion criteria. A single exclusion criterion can make you ineligible even if everything else fits. Eligibility is determined by the trial team, not by the registry status alone.
What does "randomized" mean, and does it mean I might not get the treatment?
"Randomized" means you are assigned to one of two or more groups by chance, not by your choice or your doctor's choice. In many trials, one group receives the experimental treatment and the other receives the standard treatment (or placebo). Being in the control group does not mean receiving "no treatment" — it usually means receiving the current standard of care for your condition. The informed consent form should describe the groups and what each one receives.
What does "double-blind" mean?
"Double-blind" means that neither you nor your doctor knows which treatment you are receiving. This is a design feature intended to prevent bias in how outcomes are reported and assessed — it is not a sign of distrust. In some situations (for example, if a safety concern arises), the trial team can unblind your assignment.
What is an "adverse event," and does it mean the treatment caused it?
An adverse event is any unwanted medical occurrence during the trial, whether or not it is caused by the treatment. Reporting an adverse event does not mean the treatment caused it — it means the event occurred and should be documented. The trial team assesses whether the event is related to the treatment, and how it should be managed.
What does "terminated" mean for a trial?
"Terminated" means the trial has stopped. The reasons can vary — for example, safety concerns, lack of efficacy, slow recruitment, or a sponsor decision. The term alone does not tell you why, and it does not by itself mean the treatment failed. If you were considering a trial that has been terminated, ask the trial team for the reason and for alternative options.
