coprimary en 30 secondes
- Coprimaries are equally vital research goals.
- All coprimaries must be met for study success.
- Used in clinical trials and scientific research.
- Ensures comprehensive evaluation of interventions.
The term 'coprimary' is a specialized concept primarily encountered in scientific research, particularly in fields like medicine, clinical trials, and statistics. It refers to two or more outcome measures or objectives that are considered equally essential for determining the success of a study or trial. This means that for the research to be deemed successful, it must demonstrate a statistically significant effect or result on *all* of the designated coprimary endpoints. Failing to meet the criteria for even one coprimary endpoint can render the entire study unsuccessful, regardless of the outcomes for the other coprimaries.
In essence, coprimaries elevate multiple objectives to the same level of importance. This is often done to ensure a comprehensive evaluation of an intervention or treatment. For instance, a new drug might not only need to show that it effectively reduces blood pressure (one coprimary) but also that it does so without causing significant adverse side effects (another coprimary). Both aspects are critical for regulatory approval and for informing clinical practice. The selection of coprimaries is a rigorous process, typically decided upon during the study design phase, and they are clearly defined in the study protocol. They are chosen to reflect the most important clinical questions the research aims to answer.
The use of coprimaries is a way to avoid situations where a study might appear successful based on one favorable outcome while masking a negative or neutral outcome on another equally important measure. This approach enhances the robustness and credibility of research findings. For example, in a study evaluating a new surgical technique, the coprimaries might include both the success rate of the procedure and the patient's recovery time. A high success rate alone would not be sufficient if patients experienced prolonged and painful recovery.
- Key Characteristic
- All coprimary endpoints must achieve statistical significance for the study to be considered successful.
- Application
- Commonly found in clinical trials for pharmaceuticals, medical devices, and surgical procedures where multiple efficacy and safety measures are paramount.
- Purpose
- To ensure a balanced and comprehensive assessment of an intervention's benefits and risks, preventing misleading conclusions based on a single positive outcome.
The regulatory agency reviewed the data, but the drug could not be approved because it failed to meet one of the designated coprimary endpoints related to long-term efficacy.
Understanding coprimaries is crucial for interpreting the results of clinical research and for appreciating the stringent standards applied in evaluating new treatments and medical interventions. It highlights the commitment to ensuring that any new therapy is not only effective but also safe and beneficial in multiple critical aspects.
The term 'coprimary' is a technical noun used in specific contexts, primarily academic and research-oriented. When constructing sentences, it's important to place it in a context that clearly indicates its meaning as an equally important outcome measure. It often appears in discussions about study design, results interpretation, and regulatory submissions.
Here are some ways to incorporate 'coprimary' into your sentences:
- Defining Coprimaries
- In the protocol, we clearly defined the two coprimary endpoints: reduction in tumor size and improvement in patient-reported quality of life.
- Discussing Study Success
- The investigational drug was considered a success because it met both of its coprimary objectives.
- Highlighting Failure
- Unfortunately, the trial was deemed inconclusive as the treatment did not achieve statistical significance on one of the coprimary measures.
- Explaining Research Criteria
- Regulatory approval hinges on demonstrating efficacy for each coprimary endpoint, not just a subset.
- Comparing Studies
- Unlike the previous study, this trial incorporated a third coprimary to assess cardiovascular safety more robustly.
The statistical analysis confirmed that the new therapy met both coprimary endpoints, paving the way for further clinical development.
Remember that 'coprimary' is a noun. You will often see it used with possessives (e.g., 'its coprimary endpoints') or with determiners (e.g., 'the coprimary'). It typically refers to the endpoints themselves, not the study or the outcome measure in isolation.
The term 'coprimary' is not something you'll typically hear in everyday conversations, at a dinner party, or during casual social interactions. Its usage is highly confined to specific professional and academic environments where rigorous research methodologies are discussed and implemented. The most common places you will encounter or hear this word are:
- Medical and Pharmaceutical Conferences
- Presentations and discussions by researchers, clinicians, and statisticians about the design, interim results, or final findings of clinical trials frequently involve the term 'coprimary' when explaining the success criteria.
- Academic Journals and Publications
- Research papers, especially those detailing Phase II and Phase III clinical trials, will use 'coprimary' in their methodology and results sections to define the primary objectives.
- Regulatory Agency Meetings (e.g., FDA, EMA)
- When pharmaceutical companies present data to regulatory bodies for drug approval, discussions about how the trial met its predetermined coprimary endpoints are central.
- University Lectures and Seminars
- Professors and students in advanced statistics, biostatistics, clinical research, and pharmacology programs will use 'coprimary' when teaching about trial design and interpretation.
- Internal Company Meetings in Pharma/Biotech
- Teams involved in drug development, clinical operations, and regulatory affairs will use this term frequently when strategizing and reviewing trial outcomes.
- Statistical Consulting Sessions
- Statisticians advising on study design or analyzing trial data will use 'coprimary' to discuss the critical success factors of a research project.
During the presentation, the lead statistician explained that the trial's success was contingent upon achieving significance for both coprimary endpoints.
Essentially, 'coprimary' is part of the specialized lexicon of clinical research. Think of it as a technical term within a specific professional jargon, much like 'EBITDA' in finance or 'API' in software development.
Because 'coprimary' is a technical term, many mistakes arise from its misuse in contexts where it doesn't belong, or from misunderstanding its precise meaning. Here are some common errors:
- Using it in General Conversation
- Mistake: "My two goals for this weekend are coprimary: clean the house and finish reading my book."
Correct: "My two goals for this weekend are equally important: clean the house and finish reading my book."
Explanation: 'Coprimary' is a technical research term. Using it for everyday goals trivializes its meaning and sounds unnatural. Use synonyms like 'equally important' or 'parallel' if you need to express that idea. - Confusing it with 'Primary' or 'Secondary' Endpoints
- Mistake: "The study had one primary endpoint and one coprimary endpoint."
Correct: "The study had two coprimary endpoints." or "The study had a primary endpoint and a secondary endpoint."
Explanation: 'Coprimary' by definition implies multiple endpoints sharing the highest level of importance. If there's only one 'primary' endpoint, it's not a coprimary. If there are other less important endpoints, they are 'secondary.' - Implying Unequal Importance
- Mistake: "The study met its main coprimary, but the other coprimary was only borderline significant."
Correct: "The study met its first coprimary endpoint, but the second coprimary endpoint did not achieve statistical significance."
Explanation: The essence of 'coprimary' is equal importance. Stating 'main coprimary' suggests a hierarchy that contradicts the term's definition. All coprimaries are equally primary. - Using it as an Adjective
- Mistake: "We are looking for a coprimary solution to this problem."
Correct: "We are looking for a solution that addresses two equally important aspects of this problem."
Explanation: 'Coprimary' functions as a noun, referring to the endpoints themselves. It does not modify other nouns in the way an adjective would. - Misunderstanding the 'All or Nothing' Rule
- Mistake: "The drug was successful because it showed significant improvement in one of the coprimaries."
Correct: "The drug was not considered successful because it failed to meet at least one of the coprimary endpoints."
Explanation: A key aspect of coprimaries is that *all* must be met for the study to be declared successful. If even one fails, the study does not meet its primary objectives.
The researcher mistakenly referred to the study's two main goals as simply 'primary' endpoints, overlooking the specific definition of coprimary which implies equal importance.
While 'coprimary' is a precise term used in research, several other words and phrases can convey similar ideas, depending on the context and the desired level of formality. Understanding these alternatives can help you communicate more effectively.
- Equally Important Outcomes/Objectives
- This is the most direct and easily understandable alternative. It clearly states the shared importance without using technical jargon.
- Parallel Objectives
- Suggests objectives that are pursued simultaneously and are of similar importance. It's slightly more formal than 'equally important outcomes.'
- Joint Primary Endpoints
- This phrase is very close in meaning to 'coprimary' and is often used interchangeably in research discussions. It emphasizes that these endpoints collectively serve as the primary measures of success.
- Mutually Essential Goals
- Highlights that achieving one goal is dependent on or equally critical as achieving the other for overall success. This phrase is more descriptive than a single term.
- Core Success Criteria
- This broader term can encompass coprimaries, indicating the fundamental standards by which a study's success is judged. It's less specific about the *number* of criteria but implies high importance.
- Key Performance Indicators (KPIs)
- In a business or project management context, KPIs are critical metrics for success. If a study has multiple KPIs that must all be met, they function similarly to coprimaries, though the term itself is different.
Comparison Table:
| Term | Context | Nuance |
|---|---|---|
| Coprimary | Clinical Research, Statistics | Specific technical term for two or more equally essential primary outcome measures. |
| Equally Important Outcomes | General/Academic | Clear, non-technical description. Broadly applicable. |
| Parallel Objectives | Research/Project Management | Suggests simultaneous pursuit of goals with similar importance. |
| Joint Primary Endpoints | Clinical Research | Very similar to coprimary, often used interchangeably. |
| Core Success Criteria | General/Project Management | Broader, implies fundamental measures for success, not necessarily a specific number. |
The clinical trial protocol outlined two coprimary endpoints, which were essentially joint primary endpoints for assessing the drug's efficacy and safety.

Souvent confondu avec
A primary endpoint is the main measure used to evaluate the effect of an intervention. 'Coprimary' implies there are *two or more* such main measures, all equally important. A study can have a single primary endpoint, but if it has multiple equally important ones, they are coprimaries.
Secondary endpoints are additional measures that are considered less critical than primary or coprimary endpoints. The study's success is not typically dependent on achieving significance for secondary endpoints, unlike coprimaries.
A composite endpoint is a single endpoint that combines multiple individual outcomes into one measure. While it addresses multiple aspects, it's a single combined metric, whereas coprimaries are distinct, individual measures that are all equally important.
Facile à confondre
Coprimary is derived from 'primary', leading to potential confusion about the number of main objectives.
A 'primary' endpoint is the single most important measure. 'Coprimary' specifically refers to *two or more* endpoints that are *equally* primary. Therefore, 'coprimary' is a subset of 'primary' concepts, denoting a specific configuration of multiple primary measures.
The study had one primary endpoint, but the researchers debated whether to add a coprimary to assess safety more rigorously.
Both relate to importance in research, but 'coprimary' refers to the highest level of importance (shared), while 'secondary' refers to a lower level.
'Coprimary' indicates multiple objectives that are all considered the *most* important for study success. 'Secondary' objectives are important but not critical for determining the study's overall success or failure. Think of coprimaries as the main headline news, and secondaries as feature stories.
While the drug met its coprimary endpoints, the secondary endpoints showed some promising but not statistically significant trends.
'Objective' is a general term for a goal, and coprimaries are a specific type of objective.
'Objective' is a broad term for any goal. 'Coprimary' is a technical term for a specific type of objective in research: one that is equally crucial alongside other objectives for determining study success. All coprimaries are objectives, but not all objectives are coprimaries.
The main objective of the study was to evaluate efficacy, but the coprimary objective was to assess patient tolerability.
'Coprimary' is often used in conjunction with 'endpoint' ('coprimary endpoint').
'Endpoint' refers to the measurement or outcome used to assess the effect of an intervention. 'Coprimary' specifies the *level of importance* and *number* of these endpoints (two or more, all equally primary). An endpoint can be primary, secondary, or coprimary.
The clinical trial defined its coprimary endpoints as the reduction in viral load and the absence of specific symptoms.
The prefix 'co-' in coprimary means 'jointly' or 'together', similar to the word 'joint'.
'Joint' implies something shared or done together. 'Coprimary' is a specific technical term in research that means 'jointly primary'. While 'joint primary endpoints' is a closely related phrase, 'coprimary' is the established noun used in protocols and statistical analysis plans.
The researchers used 'joint primary endpoints' in their discussion, which is conceptually similar to the idea of coprimary objectives.

Astuces
Think of 'Co-' as 'Together'
The prefix 'co-' means 'together' or 'jointly'. So, 'coprimary' means that two or more primary goals are working together, side-by-side, and are equally important. It's not just one main goal, but a partnership of main goals.
Specific to Research
This term is highly specialized and primarily used in scientific and medical research, especially clinical trials. You won't typically hear it in everyday conversation. If you're discussing research results, it's likely relevant.
All or Nothing
For a study with coprimaries, success means meeting *all* of them. If even one coprimary fails to show statistical significance, the study is generally considered unsuccessful, regardless of how well it performed on others.
Equally Critical
The key characteristic of coprimaries is their equal importance. They are not ranked; they all hold the highest level of significance for determining the study's outcome. This ensures a balanced view of the intervention being tested.
Precise Language
When writing, be clear about whether you are referring to a single primary endpoint or multiple coprimary endpoints. Using 'coprimary' incorrectly can lead to misunderstandings about the study's design and results.
When to Use Alternatives
If you are not in a research context, using phrases like 'equally important objectives' or 'parallel goals' might be more understandable than 'coprimary' to a general audience.
Stress the 'PRI'
Remember to stress the second syllable: co-PRI-ma-ry. This helps in clear communication, especially in professional settings where precise pronunciation is valued.
Plural Form
The plural of 'coprimary' is 'coprimaries'. For example, 'The study had two coprimary endpoints.'
'Joint Primary Endpoints'
'Joint primary endpoints' is a very similar term often used interchangeably with 'coprimary endpoints', emphasizing that multiple primary endpoints are considered together.
High Stakes
The designation of coprimary endpoints carries significant weight. Meeting them can lead to drug approval or widespread adoption of a new technique, while failing them can halt development or lead to rejection.
Mémorise-le
Moyen mnémotechnique
Think of 'co-' as in 'co-pilot' or 'co-worker' – someone working alongside. So, 'coprimary' means 'primary' goals working *together*, side-by-side, equally important. Imagine two race cars, both labeled 'Primary Winner', running neck-and-neck.
Association visuelle
Visualize two identical trophies side-by-side, both labeled 'Primary Success'. The 'co-' signifies they are together, and 'primary' signifies their top importance. Or, picture two equally weighted scales, both perfectly balanced, representing the two equally important outcomes.

Questions fréquentes
10 questionsA primary endpoint is the single most important measure used to determine if a study is successful. A coprimary endpoint refers to a situation where there are *two or more* primary endpoints, and all of them must achieve statistical significance for the study to be considered successful. Essentially, coprimaries are equally important primary endpoints.
Researchers use coprimary endpoints to ensure a comprehensive evaluation of an intervention. For example, a new drug might need to prove it's effective (one coprimary) and safe (another coprimary). This approach prevents a study from appearing successful based on a single positive outcome while ignoring negative results in another critical area.
If a study fails to achieve statistical significance on even one of its coprimary endpoints, the entire study is typically considered unsuccessful. This is because all coprimaries are considered equally essential for demonstrating the intervention's overall benefit and reliability.
While the term 'coprimary' is most prevalent and strictly defined in medical and clinical research, the concept of having multiple, equally important success criteria can appear in other fields like engineering, project management, or even certain social science studies. However, the specific term 'coprimary' is generally confined to scientific research contexts.
Yes, a study can have more than two coprimary endpoints, although having two is most common. The number is determined during the study design phase based on the most critical aspects that need to be evaluated. Having too many coprimaries can significantly increase the statistical complexity and the risk of the study failing.
Coprimary endpoints are chosen during the study design phase by researchers, statisticians, and often with input from regulatory bodies. They are selected based on their clinical relevance, their ability to clearly measure the intervention's intended effects (both positive and negative), and their statistical feasibility. They must represent the most critical questions the study aims to answer.
Yes, coprimary endpoints are always statistical in nature. The success of a coprimary endpoint is determined by statistical analysis, which assesses whether the observed effect is statistically significant (i.e., unlikely to be due to random chance). This is crucial for the scientific validity of research findings.
The plural form of 'coprimary' is 'coprimaries'. For example, 'The study had two coprimary objectives.'
'Coprimary endpoints' and 'joint primary endpoints' are often used interchangeably and mean essentially the same thing: two or more primary endpoints that are considered equally important. 'Coprimary' is the more established and technical term in many research protocols.
Yes, a coprimary endpoint can itself be a composite endpoint. For example, a study might have one coprimary endpoint focused on cardiovascular events (which could be a composite of heart attack, stroke, and cardiovascular death) and another coprimary endpoint focused on overall survival.

- All coprimaries must be met for study success.
- Used in clinical trials and scientific research.
- Ensures comprehensive evaluation of interventions.
Think of 'Co-' as 'Together'
The prefix 'co-' means 'together' or 'jointly'. So, 'coprimary' means that two or more primary goals are working together, side-by-side, and are equally important. It's not just one main goal, but a partnership of main goals.
Specific to Research
This term is highly specialized and primarily used in scientific and medical research, especially clinical trials. You won't typically hear it in everyday conversation. If you're discussing research results, it's likely relevant.
All or Nothing
For a study with coprimaries, success means meeting *all* of them. If even one coprimary fails to show statistical significance, the study is generally considered unsuccessful, regardless of how well it performed on others.
Equally Critical
The key characteristic of coprimaries is their equal importance. They are not ranked; they all hold the highest level of significance for determining the study's outcome. This ensures a balanced view of the intervention being tested.
Exemple
The doctor explained that both pain reduction and physical mobility were the coprimaries for my recovery plan.
