Their primary purpose is to scientifically and objectively evaluate the safety, efficacy, and adverse reactions of a new drug, providing essential evidence for drug registration. Clinical trials involve human subjects; from the perspective of clinical trial project management and quality, the most critical and challenging aspect is subject management, including subject recruitment, grouping, compliance, dropout, exclusion, and ensuring subject safety. Subject management permeates the entire clinical trial process; effective subject management is a core element, especially subject screening and grouping, as well as subject compliance, which are crucial for ensuring the smooth progress of the trial and the scientific reliability of the results.

[0084] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0085] Example 1:
[0086] This embodiment provides a drug clinical trial subject management system, such as... Figure 1 Shown, including:
[0087] The learnable model building module is used to build learnable models;
[0088] The subject screening module is used to input the multi-dimensional characteristics of subjects into a learnable model for analysis and screening to obtain target subjects.
[0089] The informed consent management module is used to manage the informed consent signing information of the target subjects;
[0090] The subject grouping module is used to group the target subject data;
[0091] The trial process management module is used to monitor and manage the post-trial observation data of the target subjects after grouping in real time.
[0092] The learnable model relearning module is used to retrain and update the learnable model after the completion of the current clinical trial.
[0093] In this embodiment, the learning model construction module establishes a continuously trainable mathematical model based on data from previous clinical trial participants using a neural network approach; the participant screening module collects and scores information from recruited participants, generates a "compliance coefficient" score for each participant using the learning model, and screens participants based on the "compliance coefficient" score; the informed consent management module manages the informed consent process, signing, and storage of informed consent forms for trial participants; the participant grouping module groups participants based on their "compliance coefficient" scores using stratified random sampling; the trial process management module manages participants' medication adherence, daily life, visits, regular check-ups, and adverse reactions; and the learning model relearning module manually scores the participants' actual "compliance coefficients" after each clinical trial, using these actual "compliance coefficient" values to retrain the learning model, thereby continuously improving the predictive accuracy of the learning model.
[0094] In this embodiment, post-trial observation data includes: the subject's medication adherence as required and daily life status, visits, regular follow-up examinations, and management of adverse reactions.
[0095] In this embodiment, the trial process management module includes: Step 1, Medication administration and recording: The research physician issues a detailed prescription according to the clinical trial protocol, specifying the subject's medication administration method, including dosage, time interval, and administration method (e.g., before meals, after meals, with warm water, etc.). Through face-to-face communication, distribution of written materials, and necessary video demonstrations, the prescription details precautions during medication administration, such as dietary restrictions and avoiding concurrent medications. This ensures the subject fully understands the medication administration method and precautions. Under the guidance of the research physician, the subject takes the medication on time as prescribed. Simultaneously, the subject needs to diligently record a subject diary card, including the time of each medication administration, post-medication physical sensations (e.g., nausea, dizziness, fatigue, etc.), and any special circumstances in daily life (e.g., strenuous exercise, alcohol consumption, etc.). During medication administration, if the subject discovers any problems or experiences discomfort, they can communicate with the research physician promptly through various channels, such as telephone, text message, and dedicated clinical trial communication software. After receiving feedback from the participants, the research physicians will promptly assess and address the issues. If a participant is found to be unable to continue the clinical trial (e.g., adverse reactions, changes in condition meeting exclusion criteria), that participant will be removed to ensure their safety. The second step involves scheduled follow-up visits: Participants are required to return to the hospital for visits strictly according to the clinical trial protocol. During these visits, the research physicians will issue comprehensive examination and testing orders based on the protocol, such as blood tests, urine tests, and imaging examinations. After the tests are completed, the research physicians will promptly conduct a professional analysis of the results, comparing and interpreting various indicators. If any potential adverse reactions are detected, the research physicians will immediately initiate the appropriate treatment procedures. Depending on the severity of the adverse reaction, different measures will be taken, such as adjusting drug dosage, suspending medication, or providing symptomatic treatment, ensuring that the participant's health status is promptly monitored and addressed. The third step involves recording case reports: During each visit, in addition to conducting routine examinations and analyzing results, the research physicians will inquire in detail about the participant's medication adherence and physical condition, and will check and confirm the participant's diary card. Throughout the process, the research physicians meticulously recorded case report forms, including basic information about the subjects, various data from the trial, examination and test results, problems encountered, and corresponding solutions. The fourth step is data processing: systematically processing the large amount of data generated during the trial. First, data management personnel questioned the data, identifying potential errors, omissions, or contradictions by establishing data logic verification rules and comparing them with original records, and promptly communicating with relevant researchers for verification. After ensuring the data's accuracy, a data locking operation was performed to seal the data and prevent unauthorized modification.After the data is locked, professional statistical analysts will use appropriate statistical analysis methods to conduct in-depth analysis of the data, such as descriptive statistics, correlation analysis, and difference tests, to uncover the underlying information and patterns. Finally, under the conditions specified in the trial protocol, the unblinding process will be performed to reveal the trial groupings. Combined with the statistical analysis results, a complete and accurate clinical trial summary report will be generated. This report will serve as an important basis for evaluating the efficacy and safety of the investigational new drug. The flowchart of the trial process management module is shown below. Figure 5 As shown.
[0096] In this embodiment, the flowchart of the informed consent management module is as follows: Figure 6 As shown, it includes: explanation of the trial protocol, questions from the subjects to the research physician, signing of the informed consent form, and recording and preservation of the informed consent form set and informed consent procedure.
[0097] The working principle and beneficial effects of the above technical solution are as follows: By constructing a learnable model and inputting the multi-dimensional characteristics of the subjects into the learnable model for analysis and screening, target subjects are obtained. The informed consent information of the target subjects is managed, and the target subject data is grouped. The post-trial observation data of the grouped target subjects is monitored and managed in real time. After the completion of the current clinical trial, the learnable model is retrained and updated. On the one hand, this provides more efficient and accurate subject screening and grouping services for clinical trials, helping to improve the success rate and research value of clinical trials. On the other hand, the learnable model constructed by this invention has relearning capabilities. After a clinical trial ends, the generated data can be used to provide the learnable model for further training to improve the accuracy of model predictions.
[0098] Example 2:
[0099] Based on Example 1, this example provides a drug clinical trial subject management system with a learnable model building module, including:
[0100] The data collection unit is used to collect basic personal information data of participants in historical clinical trials;
[0101] Quantitative scoring units are used for:
[0102] The basic personal information data of participants in historical clinical trials were analyzed, and each characteristic of the clinical trial participants was quantitatively scored based on the analysis results.
[0103] The input vector for constructing a learnable model is based on the first quantization score.
[0104] The clinical trial performance of participants in historical clinical trials is given a second quantitative score, and the results of the second quantitative score are used as the output value of the learnable model.
[0105] The learning unit is used to acquire a preset neural network and learn from the preset neural network based on the input vector and output value to obtain a learnable model.
[0106] In this embodiment, the basic personal information data of the clinical subjects includes: age, gender, education level, economic status, health status, and occupation.
[0107] In this embodiment, data related to 1000 previous clinical trial participants were collected, including information such as age, gender, education level, economic status, health status, and occupation. Detailed medical history records were also collected, such as past disease diagnoses, treatment processes, surgical history, and allergy history; as well as various physiological examination indicators, such as complete blood count, urinalysis, liver function, kidney function, electrocardiogram, and imaging examination results. Analysis of this clinical data provides a preliminary understanding of the participants' health status and disease background, offering important evidence for subsequent screening. For example, when collecting data from participants in cardiovascular disease clinical trials, data such as blood pressure, blood lipids, and electrocardiograms were obtained from hospital cardiology medical records; these data directly reflect the participants' cardiovascular health status.
[0108] In this embodiment, the second quantitative score refers to the "compliance coefficient" score of the participants in the historical clinical trials. The score is between 0 and 10, with higher scores for better compliance and lower scores for worse compliance. The "compliance coefficient" scores of these 1,000 participants in the previous clinical trials can be determined as the output value of the learnable model (k = 1, 2, ... 1000).
[0109] In this embodiment, a preset neural network is obtained, and the preset neural network is learned based on the input vector and output value to obtain a learnable model. This includes: establishing a learnable model using a neural network method to generate the "compliance coefficient" for each subject. The neural network-based learnable model includes an input layer, a hidden layer, and an output layer, which are described below:
[0110] a: Input Layer: The input layer contains 6 nodes, each corresponding to a score for one of the six features mentioned above. Each node's value ranges from 0 to 10. Let the input vector be a{x}={x1,x2,x3,x4,x5,x6}, where x1 is the age score, x2 is the gender score, x3 is the education level score, x4 is the income score, x5 is the health status score, and x6 is the occupation score.
[0111] b: Hidden layer: The hidden layer has 10 nodes. The transformation from the input layer to the hidden layer can be represented as:
[0112]
[0113] Where h j Let f be the output of the j-th node in the hidden layer, and f be the activation function. Let x be the weight from the i-th node in the input layer to the j-th node in the hidden layer. i Let x1 be the age score, x2 be the gender score, x3 be the education level score, x4 be the income score, x5 be the health status score, and x6 be the job nature score. This is the bias of the j-th node in the hidden layer.
[0114] In this study, the ReLU (Rectified Linear Unit) function was chosen as the activation function f, and its mathematical expression is as follows:
[0115] f(x) = max(0,x)
[0116] This expression indicates that when the input value x is greater than 0, the output value of the ReLU function is equal to the input value x, meaning the neuron linearly transmits the positive input signal. On one hand, the ReLU function calculation process is extremely simple, requiring only one comparison and selection operation, which greatly reduces computational costs and improves the training speed of the model. On the other hand, during model training, the derivative of the ReLU function is always 1 when the input is positive. This allows the gradient to be effectively propagated during backpropagation, avoiding the vanishing gradient phenomenon, helping the model converge faster, and also enabling better feature extraction from the data, enhancing the model's ability to process complex data.
[0117] c: Output Layer: The output layer has only one node, outputting a value y between 0 and 10. This value is the "compliance coefficient" that this invention needs to obtain. The transformation from the hidden layer to the output layer is as follows:
[0118]
[0119] Where y is the output of the output layer. Let b be the weight from the j-th node in the hidden layer to the output layer. 2 The output layer is biased. Similarly, the output layer also uses the ReLU function as the activation function. The output value y of the output layer ranges from 0 to 10. The ReLU function can ensure that the output value is within a reasonable range, and at the same time, it utilizes its non-linear characteristics to enable the model to better fit the complex relationship between the data and the true "compliance coefficient".
[0120] Learnable model training:
[0121] Collect relevant data from 1000 previous clinical trial participants, including information such as age, gender, education level, economic status, health status, and occupation. Using the method described in the first step, score each of these 1000 participants to establish the model's input vector a{x}k={x1,x2,x3,x4,x5,x6}k, (k=1,2,……1000).
[0122] The "compliance coefficient" of these 1000 previous clinical trial participants was manually scored, with scores between 0 and 10, and these scores were used to determine the true values y that the learnable model could output. k , (k = 1, 2, ..., 1000).
[0123] The model training employs the backpropagation (BP) algorithm. This algorithm calculates the error between the predicted and actual values, then propagates this error back from the output layer to the input layer. This process adjusts the weights and biases of each layer, gradually reducing the error. A loss function is used to measure the error between the model's predictions and the actual values. Based on the application characteristics of this invention, mean squared error is used as the loss function. By minimizing the loss function, the model can continuously adjust its parameters to improve prediction accuracy.
[0124] For the predicted values output by the model and the true value y k (k = 1, 2, ... 1000), the formula for calculating the mean square error is: Where N is the number of samples, and in this invention, the initial training sample size N = 1000. In the learnable model constructed in this invention, we expect the "compliance coefficient" output by the model to be as close as possible to the true "compliance coefficient". Mean squared error can effectively quantify this degree of closeness. By continuously minimizing the mean squared error, the model can learn the complex relationship between various factors and the comprehensive score, thereby achieving accurate screening of subjects.
[0125] During training, gradient descent is used to update the weights. and bias b 2 For weights and bias The updated formula is:
[0126] Where η is the learning rate, which determines the step size of each parameter update. In this invention, the learning rate η = 0.01 is set, which is a suitable value determined after multiple experiments and adjustments. and These represent the loss function L with respect to the weights. and bias The gradient of (l=1,2) is calculated by taking j=1 when calculating the weights and biases of the output layer, since the output layer has only one node. Therefore, j can be omitted in the expression. By calculating the gradient, we can determine in which direction the weights and biases can be adjusted to reduce the loss function value. During backpropagation, the chain rule is used to calculate the gradient of each layer from the output layer to the input layer. By repeatedly calculating the loss function, gradient, and updating the weights and biases, the performance of the learnable model of this invention gradually improves. Thus, using the collected data from 1000 previous clinical trial subjects, the learnable model of this invention is obtained through training and is ready for use. The learnable model construction module diagram is shown below. Figure 2 As shown.
[0127] The working principle and beneficial effects of the above technical solution are as follows: by collecting personal basic information data of historical clinical subjects, the input vector of the learnable model can be effectively obtained; the output value of the learnable model can be effectively obtained through the second quantization scoring; and then the learning of the neural network of the language language can be effectively realized through the input vector and output value, thereby ensuring the accuracy of building the learnable model and helping the learnable model to process complex data.
[0128] Example 3:
[0129] Based on Example 2, this example provides a drug clinical trial subject management system. In the quantitative scoring unit, the system analyzes the basic personal information data of historical clinical trial participants, including:
[0130] The feature dimension determination subunit is used to analyze the personal basic information data of historical clinical trial participants, and to obtain multiple feature dimensions corresponding to the personal basic information data and the information representation under each feature dimension.
[0131] The first quantitative scoring unit is used to obtain the scoring reference range under each feature dimension, compare the information representation under the corresponding feature dimension with the scoring reference range, and output the first quantitative score corresponding to each feature dimension.
[0132] The input vector determination sub-unit is used to integrate the first quantization score corresponding to each feature dimension to obtain a multi-dimensional feature vector, and use the multi-dimensional feature vector as the input vector of the learnable model.
[0133] In this embodiment, the information representation under each feature dimension is the data content corresponding to each feature dimension. The feature dimensions include: age, gender, education level, income, health status, and job nature.
[0134] In this embodiment, a first quantitative score is performed on each feature dimension of the clinical trial subjects. For example, each feature of these 1000 previous clinical trial subjects is quantitatively scored, with a score between 0 and 10. 1) x1 is the age score: age is divided into corresponding scores according to different age groups (e.g., 8 points for 18-30 years old, 6 points for 31-50 years old, etc.); 2) x2 is the gender score: male is set to 5 points, female is set to 5 points (the weight can be adjusted according to actual needs); 3) x3 is the education level score: education level is divided into educational level (2 points for primary school and below, 4 points for junior high school, and 4 points for senior high school / vocational school). 6 points, junior college 8 points, bachelor's degree and above 10 points); 4) x4 is the income score. Income (10 points for annual income of over 1 million, 8 points for 500,000 to 1 million, 6 points for 300,000 to 500,000, 4 points for 100,000 to 300,000, 2 points for 50,000 to 100,000, etc.); 5) x5 is the health score. Health is assessed and scored based on detailed medical examination reports and medical history (10 points for good health, 6 points for minor chronic diseases, etc.); 6) x6 is the job nature score. Job nature is scored based on factors such as work intensity and environment (8 points for easy and good environment, 4 points for high intensity or harsh environment, etc.).
[0135] The working principle and beneficial effects of the above technical solution are as follows: by determining the information representation and scoring reference range corresponding to each feature dimension, it is possible to effectively perform the first quantitative scoring on each feature dimension, and to effectively obtain the input vector based on the first quantitative scoring result, thus ensuring the accuracy of building a learnable model.

[0143] In this embodiment, the first number of subjects is greater than or equal to the second number of subjects.
[0144] The working principle of the above technical solution is as follows: The subject screening module consists of the following steps: First, subject information collection and processing: Collect information on all recruited subjects, including age, gender, education level, economic status, health status, and occupation. Then, following the method described in the first step of the "learnable model construction module," obtain the input vector a{x}={x1,x2,x3,x4,x5,x6} of the learnable model for each subject. Second, subject "compliance coefficient" calculation: Input the input vector a{x}={x1,x2,x3,x4,x5,x6} of the learnable model for each subject into the model already constructed in the "learnable model construction module." The "learnable model" calculates its output value y, which is the subject's "compliance coefficient (i.e., target score)," thereby calculating the "compliance coefficient" for all subjects. Third, subject "compliance coefficient" ranking: Rank all subjects according to the magnitude of their "compliance coefficient" values. The fourth step is participant selection: Based on the number of participants determined in the clinical trial plan, participants with high compliance scores are selected according to the ranking results of the "compliance coefficient" from the previous step.

[0167] In this embodiment, the flowchart of the learnable model relearning module is as follows: Figure 7 As shown.
[0168] The working principle of the above technical solution is as follows: First, the true value of the subject's "compliance coefficient" is scored: After a clinical trial, each subject participating in the trial is manually scored on the "compliance coefficient", resulting in a true value y for each subject's "compliance coefficient". k (k = 1, 2, ..., total number of participants), and the score of participants who are eliminated or drop out during the trial is uniformly 1 point. The second step is retraining the learnable model: using the method described in "Step 3, Learning Model Training" of the "Learable Model Construction Module", the input vector a{x}k = {x1, x2, x3, x4, x5, x6}k (k = 1, 2, ..., total number of participants, excluding those who failed the screening) of the learnable model for each participant, obtained from "Step 1, Participant Information Collection and Processing" of the "Participant Screening Module", and the true value y of each participant's "compliance coefficient". k (k = 1, 2, ..., total number of participants), and train the model again. The third step is retraining the learnable model: after retraining, the weights in the learnable model can be updated. and bias b 2 The model was saved for use in the next clinical trial.
[0169] The beneficial effect of the above technical solution is that after a clinical trial is completed, the data generated can be used to provide the learnable model for further training, so as to improve the accuracy of the model's predictions.
