Clinical trial information processing system and method

CLAIM OF PRIORITY

The present application claims priority from Japanese application JP 2005-312102 filed on Oct. 27, 2005, the content of which is hereby incorporated by reference into this application.

FIELD OF THE INVENTION

The present invention relates to a system to support establishing contracts binding the facility or site performing clinical trials such as the hospital, with the sponsor requesting a clinical trial such as a pharmaceutical company.

BACKGROUND OF THE INVENTION

A pharmaceutical company who develops a pharmaceutical that renders pharmacodynamic effects is required by law to obtain the prior approval and certification of the Ministry of Health before using that drug at medical facilities such as hospitals or selling it at drugstores. To obtain that certification the safety and effectiveness (potency) of that drug must be confirmed by administering that yet uncertified drug to actual patients and to healthy volunteers. The testing and investigation of this newly developed drug is called a clinical trial.

The main problem in clinical trials is that finding participants (trial subjects) is difficult. Speedily obtaining trial subjects is a matter of critical importance to the pharmaceutical companies in terms of development costs for the new drug. The concept called the trial subject panel is one solution for obtaining participants (trial subjects). This trial subject panel is a list made by registering volunteers in advance as potential trial subjects. In Europe and the US this trial subject panel is called a volunteer database (hereon also called volunteer database). This volunteer database is generally formed from introductions from people who participated in other clinical trials, information from physical examinations, introductions from other medical facilities, and introductions from patients, etc. In most cases these are medical facility volunteer databases.

If a volunteer database is available, the medical facility can efficiently recruit participants when a request for a clinical trial arrives since a trial subject list can be formed by referring to that same volunteer database. Moreover, if the drug is administered to the participant (hereafter called trial subject) immediately after the clinical trial request, then the time that administering the drug automatically ends is clearly known so administering the drug can end in a short time.

The contract between the sponsor and the site for the clinical trial is established by determining the number of cases indicating how many trial subjects will be used, the trial period indicating when the clinical trial will end, and the clinical trial expenses the sponsor will pay the clinical trial site. Generally, the clinical trial expenses are handled in case unit costs found by dividing the trial expenses by the number of cases.

[Patent document 1] JP-A No. 41657/2002

SUMMARY OF THE INVENTION

The effect obtained from utilizing the volunteer database was described above, however there are few medical facilities (hereafter trial sites) actually using them. Moreover the pharmaceutical company (hereafter called sponsor) requesting the site to make a clinical trial had no choice but to enter into a contract while the trial site had only a rough idea of the number of cases. A contract was established by the sponsor visiting the trial site so that the trial site was unable to select clinical trials on its own. Also, the same case units were utilized regardless of whether the clinical trial period was long or short so the doctors in charge of the trials showed a trend to be positive about the trials in their final period rather than their initial period.

In view of the above problems with these types of clinical trials, this invention has the object of providing a clinical trial information processing system and clinical trial information processing method capable of functioning between the sponsor and trial site to make the clinical trial more efficient.

The clinical trial information processing system of this invention includes a means for establishing contract conditions including the number of cases, the completion period, the case unit costs, a means for disclosing those same contract conditions, a means for recruiting for those same contract conditions, a means for eliminating conflicts between identical contract conditions, a means for storing information to rank the trial sites, a means to rewrite that same ranking information. As one example, the clinical trial information process server of this invention stores information relating to the sponsor and information relating to the trial site, and trial basic information including the trial target disease name, the total length of trial (trial period), total number of cases and total budget registered by the sponsor, and trial contract conditions including the trial name, trial period, number of cases and budget are stored in a clinical trial database; and a process and information service unit distributes information on trial contract conditions registered in the contract condition information storage area to the trial site, registers applicant trial sites for trial relating to the distributed trial contract conditions, and distributes the status of applicant responses for trial contract conditions, to the sponsor who registered matching contract conditions.

This invention is capable of contracts where the number of cases is based on evidence in a database. The trial site can freely select the clinical trial. Moreover, the doctor can be positively motivated to perform the clinical trial from its very start since clinical trials with a high number of case units can be accepted.

The clinical trial contract support system 440 handles the input information and each interface distributed by the information service unit 1000 in FIG. 11 from FIG. 19. The contract condition calculation unit 1010 starts up when setting contract conditions for the trial, and automatically generates suitable contract conditions that can be selected by the trial sites a, b, c, based on the period (trial length), (total) number of cases and (total) budget registered by sponsors A and B. The subscription rival calculation unit 1020 starts up when there is a deluge of multiple competing trial sites responding to the contract condition, and refers to the rating information table 900 to automatically select a suitable trial site. The site rating information update unit 1030 starts up when the information in the trial result information table 820 is updated (rewritten), and updates (rewrites) the information in the site rating information table 900.

Utilizing the above structure allows the information service unit 1000 to provide appropriate information to the sponsors A, B and the trial sites a, b, and c, and collect information needed for the contract. The contract condition calculation unit 1010 automatically generates suitable contract conditions that can be selected by the trial sites a, b, c, based on the period, number of cases, and budget information relating to the clinical trial registered by the sponsors A, B, and can therefore eliminate the troublesome task of setting contract conditions that should be set by the sponsors. The subscription rival calculation unit 1020 refers to the site rating information to automatically eliminate conflicts when there is a deluge of responses from multiple trial sites for the proposed contract conditions generated by the contract calculation unit 1010 and relating to ratings updated by the site rating information update unit 1030. This calculation unit 1020 therefore reduces the task of eliminating competing sites that the sponsor should itself perform. The task of eliminating competing sites utilizes the rating information based on result information from trials performed in the past so that the ratings are performed based on facts. The site rating information update unit 1030 collects result information from the trial sites relating to trials implemented from established contracts, and updates the rating information based on the result information. In this way, rather than just performing a trial that was commissioned, the sponsor and the trial site can obtain rating information when entering into a new contract, by means of feedback conveyed as result information.

The sponsors A, B utilize the trial basic information registration interface 1300 to register trial information requested of the trial sites a, b, c, in advance so that the trial sites a, b, c, can themselves select a desired clinical trial.

FIG. 14 is a drawing of the interface allowing the sponsor to register contract condition information. The reference numeral 1400 is a contract condition registration interface for registering information in the contract condition information table 720; reference numeral 1410 is a length of trial entry area for entering the trial period in the length of trial area 732; reference numeral 1420 is a number of trial sites entry area for entering the number of trial sites into the number of trial sites area 733; reference numeral 1430 is a number of cases entry area for entering the number of cases into the number of cases area 734; reference numeral 1440 is a unit cost entry area for entering the unit cost into the unit cost area 735; reference numeral 1450 is a subtotal number of cases display area for displaying a subtotal of the number of cases as the product of the number of cases displayed in the number of cases entry area 1430 and the number of trial sites displayed in the number of trial sites entry area 1420; reference numeral 1460 is the (trial) subtotal cost display area for displaying the subtotal of trial costs as the product of the unit cost displayed in the unit cost entry area 1440 and the subtotal of the number of cases displayed in the number of cases display area 1450; and the reference numeral 1470 is a registration button for registering the above information in the clinical trial contract support database 420.

The information service unit 1000 starts the contract condition calculation unit 1010 when the sponsors A, B press the contract condition calculation button 1395. The contract condition calculation unit 1010 generates multiple contract conditions based on the trial period entered in the total length of trial entry area 1360, the total number of cases entered in the total number of cases entry area 1370, and the total cost entered in the total cost entry area 1380.

The contract conditions for example for the trial period (length of trial) are generated by multiplying the trial period entered in the total length of trial area by 1, 0.5 or 0.25 times. The number of cases is generated in the same way, by multiplying the total number of cases entered in the total number of cases entry area 1370 by 1, 0.5 or 0.25 times. The market determines the value of the (case) unit cost to some extent so case unit cost proposal conditions may be generated by multiplying the applicable figure by 1, 1.2, or 1.4 times. The number of trial sites may be calculated by solving the simultaneous equation for that value. The method for calculating the contract conditions is not limited to the above examples.

The information service unit 1000 loads the contract conditions generated as described above, and displays them on the contract condition registration interface 1400. The sponsor A, B depresses the registration button 1470 if the displayed contract conditions are suitable. If these contract conditions are not suitable, then the sponsors A, B change the figures displayed in the number of trial sites entry area 1420, number of cases entry area 1430, and unit cost entry area 1440 to correct them to suitable values. In this case, the information service unit 1000 recalculates the figures so that no conflicts occur in the figures displayed in the subtotal number of cases display area 1450 and the subtotal cost display area 1460.

The information service unit 1000 registers the contract condition information displayed on the contract condition registration interface 1400 into the contract condition information table 720 when the sponsors A, B depress the registration button 1470. The contract condition calculation unit 1010 can in this way generate suitable contract conditions selectable by the trial sites a, b, c, based on the period (length of trial), total case count and total cost information on the trial registered by the sponsors A, B, so that the troublesome task of the sponsors themselves setting the contract conditions can be eliminated.

By using the above interface to display the trial subjects statistic information, the sponsor can acquire basic data for selecting the best site for the trial from among multiple trial sites.

FIG. 20 is a drawing of operation of the clinical trial contract support center shown along a time axis. The sponsors A, B first of all register the sponsor information in the clinical trial contract support center 150 and acquire access rights to the clinical trial contract support system of this invention (step 2000). The sponsors next register in the clinical trial contract support center 150 the trial basic information they wish to request (step 2010), and also register the contract condition information generated based on the trial basic information (step 2020), and then terminate registration of the trial information.

The trial sites a, b, c, on the other hand, register their own trial site information in the clinical trial contract support center 150 and acquire access rights to the clinical trial contract support system of this invention (step 2030). The sites a, b, c next view the registered trial information and subscribe to a contract condition for a desired trial (step 2040). At this point only registration has been performed and there is no contract.

The sponsors A, B confirm the contract (step 2050) at the approximate point in time that contract registration was performed, and a contract between the sponsors A, B and the trial sites a, b, c is established according to the confirmed information.

The trial sites a, b, c that received the order for a trial, promptly start the trial, and register the result information (step 2060) when the trial is complete. The clinical trial contract support center 150 updates the rating information based on the result information, and prepares for competing applications for a new contract.

On the other hand, in order to enhance the appeal of their own institution in terms of its ability to perform trials, the trial sites a, b, c enter trial subjects statistic information in the clinical trial contract support center 150 (step 2070). The step 2070 need not be implemented after the step 2060, and the trial site information in step 2030 can be executed any time if registration was completed.

In order to find the best trial site to request performing a trial, the sponsors A, B, access the clinical trial contract support center 150, display the trial subjects statistic information (step 2080), and acquire the latest information on the trial sites. The step 2080 need not be implemented after the step 2050, and the sponsor information in step 2000 can be executed any time if registration was completed.

The processing procedures used by the sponsors A, B are described using FIG. 21, FIG. 22, and FIG. 23. The processing procedures used by the trial sites a, b, c, are described using FIG. 24 and FIG. 25.

The above processing allows the sponsor to disclose trial information and contract conditions for the trial the sponsor wants to request, and allows the trial site to view the disclosed information and freely select a desired trial for their own institution. Moreover, the sponsor can collect result information from the trial sites relating to trials already performed, and by then updating the rating information based on that result information, the sponsor can obtain information for making evaluations when forming a new contract with the trial site. Also, by managing the trial subjects statistic information, the trial sites can enhance their appeal to the sponsor by showing the ability of their institution to perform trials. The sponsor can also acquire basic data for selecting the best site from among multiple trial sites.

FIG. 21 is a flow chart showing the overall procedures performed by the sponsor in the clinical trial contract support system.

When the sponsors A, B access the clinical trial contract support system using the terminal 200 (step 2100), the information service unit 1000 refers to the sponsor information table 600 and decides if registration of sponsor information is complete or not (step 2110). When registration of sponsor information is not complete, the sponsor information registration interface 1100 shown in FIG. 11 appears, and urges the sponsor A, B to enter the sponsor information. When the sponsor A, B depresses the registration button 1180, the information service unit 1000 terminates the process (step 2120) after the sponsor information was entered I the sponsor information table 600, and authenticates the user (step 2130). If registration of the sponsor information was finished in step 2110, the user authentication is performed (step 2130). If the user authentication failed in step 2130, then the process terminates (step 2180).

When the user authentication in step 2130 succeeds, then the menu can be selected. In step 2140, the trial information registration process is executed (step 2150) when the trial information registration menu was selected, and the process returns to step 2140. When the contract confirmation menu was selected in step 2140, the contract confirmation processing is executed (step 2160) and the process returns to step 2140. When the trial subjects statistic information display menu is selected in step 2140, the trial subjects statistic information display interface shown in FIG. 19 appears (step 2170) and the process returns to step 2140. When the end menu was selected in step 2140, then the process terminates (step 2180).

The trial information registration process is described utilizing FIG. 22. The contract confirmation process is described utilizing FIG. 23.

By registering site information and contract conditions in advance using the above process of this invention, the trial site can select desired trial and contract conditions from the applicable information.

By managing the trial subjects statistic information in this way, the sponsor can acquire basic data for selecting the best trial site for the trial from among multiple trial sites.

FIG. 22 is a flow chart showing the procedures in the trial information registration process.

When the trial information registration process 2150 is executed (step 2200), the clinical trial contract support system refers to the trial basic information table 700, and decides if registration of the trial basic information was completed (step 2280). In step 2210, if registration of the trial basic information is not complete, then the trial information registration interface 1300 appears and urges the sponsors A, B to enter the trial basic information. When the sponsors A, B depress the registration button 1390, the information service unit 1000 registers the trial basic information in the trial basic information table 700 (step 2220).

The information service unit decides the button was depressed (step 2230), and the process terminates if the finish button 1398 is pressed (step 2280). In step 2230, when the contract condition calculation button 1395 was depressed, the conditions calculated by the contract condition calculation unit 1010 are loaded, and displayed on the contract condition information registration interface 1400 shown in FIG. 14, urging the sponsors A, B to enter the contract condition information. When the sponsors A, B have changed (step 2240) the contract condition information displayed on the contract condition information registration interface 1400, the information service unit 1000 recalculates and displays the subtotal number of cases display area 1450 and subtotal cost display area 1460 based on the applicable changed values (step 2250).

The sponsors A, B decide if the contract condition information displayed on the contract condition information registration interface 1400 is suitable or not (step 2260). If not suitable then the sponsors A, B depress the registration button 1470. The information service unit 1000 registers the contract condition information in the contract condition information table 720 (step 2270) according to the button pressed. When the sponsors A, B decide the contract condition information in step 2260 is not suitable, the process returns to step 2240 to change the contract condition information.

By registering the trial basic information and contract conditions in advance as in the above process, the trial sites can select the desired trial and contract conditions from the applicable information. Also, the contract condition calculation unit 1010 automatically calculates conditions suitable for selection by the trial site so that the trouble of the sponsors themselves setting the contact conditions can be eliminated.

FIG. 23 is a flow chart showing the procedure for the contract confirmation process.

When the contract confirmation process 2160 is executed, the contract confirmation interface 1600 shown in FIG. 16 appears (step 2300). The sponsors A, B view the subscribing trial sites entry area 1610 and decide if there are competing subscription or not from the trial sites subscribing to the contract trial site conditions (step 2310). If there is competition, then the sponsors A, B depress the rival cancellation button 1620 (step 2320). When this rival cancellation button is depressed, the subscription rival calculation unit 1020 refers to the site rating information table 900, and eliminates competing trial sites (step 2330), and redisplays the results on the contract confirmation interface 1600.

The sponsors A, B next decide if the contract with the subscribing trial sites displayed in the contract confirmation interface 1600 is suitable or not (step 2340). If suitable then the sponsors A, B depress the decision button 1630 (step 2350). When the confirmation button 1630 is depressed, the information service unit 1000 registers the confirmed contract information in the comfirmed contract information table 800 (step 2360), and the process terminates (step 2370). If there is no competition among subscribing trial sites in step 2310, then the process proceeds to step 2350.

Providing an subscription rival calculation unit 1020 allows automatically eliminating competition after checking the rating information, when there is a deluge of applications from trial sites subscribing to a certain contract condition, and eliminates the task of the sponsors themselves eliminating competing sites.

FIG. 24 is a flow chart showing the overall procedure in the process on the trial site side in the clinical trial contract support system.

When the trial sites a, b, c use the terminal 300 to access the clinical trial contract support system (step 2400), the information service unit 1000 refers to the trial site information table 620, and decides whether or not the trial site information was registered or not (step 2410). In step 2410, when the trial site information was registered, then the trial site information registration interface 1200 appears as shown in FIG. 12, urging the trial sites a, b, c to enter the trial site information. When the trial sites a, b, c depress the registration button 1290, the information service unit 1000 terminates the process (step 2420) after registering the trial site information in the trial site information table 620. The user authentication is then executed (step 2430).

In step 2410, user authentication is executed (step 2430) when registration of the trial site information is complete. When user authentication has failed in step 2410, the process terminates (step 2480). When user authentication has succeeded in step 2430, menu selection can be performed (step 2440).

In step 2440, when the contract subscription menu was selected, the contract subscription process is executed (step 2450) and the process returns to step 2440. When the trial results information registration menu was selected in step 2440, the trial results information registration interface 1700 appears as shown in FIG. 17 (step 2460) and the process returns to step 2440. When the trial subjects statistic information registration menu was selected in step 2140, then the trial subjects statistic information registration interface 1800 appears (step 2470), and the process returns to step 2440. When the end menu was selected in step 2440, then the process terminates (step 2480). The contract subscription process is described in detail next using FIG. 25.

The above process allows the trial site to select a desired trial and contract conditions from the pre-registered trial information and contract conditions. Moreover by managing the trial subjects statistic information, the trial sites can impress the sponsor with their site's capability to perform trials. Further, by managing the result information from trials that were actually performed, the information from responses from competing trial sites can be utilized as evaluation information when entering into a contract.

FIG. 25 is a flow chart showing the sequence in the contract subscription process.

When the contract subscription process 2450 is executed, the contract subscription interface 1500 shown in FIG. 15 appears (step 2500). The trial sites a, b, c decide if there is a desired item among the contract condition displayed on the contract subscription interface 1500 (step 2510), and the process terminates if there are no desired contract conditions (step 2570).

If in step 2510, the trial sites a, b, c find a desired contract condition, and if they wish to view detailed information relating to the trial, then trial sites a, b, c depress the detailed information button 1510. The information service unit 1000 displays detailed information (step 2530) relating to the trial if the detailed information button 1510 is pressed. The interface for displaying the information resembles the trial information registration interface 1300 shown in FIG. 13. The detailed display relating to the trial terminates, and to select a desired contract condition the trial sites a, b, c next enter a check in the contract condition checkbox area 1520 (step 2540), and depress the subscription button 1530 (step 2550). The information service unit 1000 then registers the applicable conditions and the matching trial site into the confirmed contract information table 800 (step 2560). In step 2510, the trial sites a, b, c find the desired contract conditions, and if not wishing to view the detailed information on the trial, next proceeds to step 2540 and select the desired contract conditions.

The above process allows the trial site to select a desired trial and contract conditions from the pre-registered trial information and contract conditions.

If the trial sites a, b, c utilize this type of interface to register the desired trial conditions and contract conditions in advance, then the trial sites can select the best trial from among those registered by the sponsors.

FIG. 30 is a drawing showing the operation of the clinical trial contract support center of the second embodiment of this invention.

The sponsors A, B first of all register the sponsor information into the clinical trial contract support center 150, and acquire access rights to the clinical trial contract support system of this invention (step 2000). Next, the sponsors register the trial basic information they want to request, into the clinical trial contract support center 150 (step 2010), and also register the contract condition information generated based on that trial basic information (step 2020) and complete registration of the trial information.

After completing registration of the trial information, the trial sites a, b, c first of all register their own trial site information into the clinical trial contract support center 150, and acquire access rights to the clinical trial contract support system of this invention (step 2030). The trial sites next register information relating to the desired trial to execute (step 3000). At this point, only registration is performed and the contract is not yet confirmed. The step 3000 may be executed prior to the step 2010 and the step 2020.

The sponsors A, B confirm the contract (step 2050) at the approximate point in time that contract condition was performed, and a contract between the sponsors A, B and the trial sites a, b, c is established according to the confirmed information. The trial sites a, b, c that received the order for a trial, promptly start the trial, and register the result information (step 2060) when the trial is complete. The trial contract support center updates the rating information based on the result information, and prepares for competing applications for a new contract.

In order to find the best trial site to request performing a trial, the sponsors A, B, access the clinical trial contract support center 150, display the trial subjects statistic information (step 2080), and acquire the latest information on the trial sites. The step 2080 need not be implemented after the step 2050, and the trial sponsor information in step 2000 can be executed any time if registration was completed.

In this embodiment if the trial site pre-registers its desired trial information and contract conditions, and the sponsor pre-registers its desired trial information and contract conditions, then the clinical trial contract support system can match the applicable information so that the clinical trial contract support system can establish a trial contract with ideal contract conditions for both the trial site and the sponsor.

FIG. 31 is a flow chart showing in detail the procedure for confirming the contract in the second embodiment of this invention.

When the contract confirmation process 2160 is executed (step 3100), a search is first made of the executable trial information table 2700, and a decision made whether or not there is registered executable trial information (step 3110). In step 3110, the matching unit between contract conditions and executable trials 2800 starts up when registration was completed. The matching unit between contract conditions and executable trials 2800 then matches the information in the contract condition information table 720 with the information in the executable trial information table 2700, extracts the trial sites that fulfill the contract conditions, and registers information on those trial sites in the confirmed contract information table 800 (step 3120). The contract confirmation interface 1600 then appears.
