Description:
CLAIM OF PRIORITY  
       [0001]     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  
       [0002]     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  
       [0003]     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.  
         [0004]     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.  
         [0005]     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.  
         [0006]     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.  
         [0007]     [Patent document 1] JP-A No. 41657/2002  
       SUMMARY OF THE INVENTION  
       [0008]     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.  
         [0009]     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.  
         [0010]     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.  
         [0011]     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.

         [0069]     The clinical trial contract support system  440  manages the information rating (or ranking) for each trial site, and can utilize this information as rating information when (sites are) competing for a contract. By managing the target disease and the number of trial subjects per target disease in the same way, the latest information on the trial sites can be provided to the sponsors. By managing the ranking information on each trial site, that information can be utilized as rating information when trial sites are competing for a new contract. Also, monitoring the statistical information in the database allows the trial site to enhance the appeal of its own institution ability to accept and handle trials. Moreover the sponsor can acquire basic data for selecting the best site for the trial from among multiple trial sites.

The reference numeral  1000  is an information service unit for distributing each interface shown in  FIG. 11  from  FIG. 19  to the terminal  200  for sponsors A, B, and the terminal  300  for the trial sites a, b, c. The reference numeral  1010  is a contract condition calculation unit for generating each type of contract condition shown in detail in  FIG. 14 . The reference numeral  1020  is an subscription rival calculation unit for eliminating competition when there is a deluge of responses from multiple trial sites for the contract condition shown in detail in  FIG. 16 . Reference numeral  1030  is a site rating information update unit for updating (rewriting) the rating information utilized for rating when eliminating competition with the subscription rival calculation unit  1020 . The site rating information update unit  1030  is described in detail in  FIG. 17 .  
         [0071]     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 .  
         [0072]     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.

         [0079]      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 .  
         [0080]     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 .  
         [0081]     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.  
         [0082]     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 .  
         [0083]     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.  
         [0084]      FIG. 15  is a drawing of the interface for the trial site to subscribe to the contract condition.

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 ).  
         [0105]     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 ).  
         [0106]     The trial information registration process is described utilizing  FIG. 22 . The contract confirmation process is described utilizing  FIG. 23 .  
         [0107]     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.  
         [0108]     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.  
         [0109]      FIG. 22  is a flow chart showing the procedures in the trial information registration process.  
         [0110]     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 ).  
         [0111]     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 ).  
         [0112]     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.  
         [0113]     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.  
         [0114]      FIG. 23  is a flow chart showing the procedure for the contract confirmation process.  
         [0115]     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 .  
         [0116]     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 .  
         [0117]     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.  
         [0118]      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.  
         [0119]     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 ).  
         [0120]     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 ).  
         [0121]     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 .  
         [0122]     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&#39;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.  
         [0123]      FIG. 25  is a flow chart showing the sequence in the contract subscription process.  
         [0124]     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 ).  
         [0125]     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.  
         [0126]     The above process allows the trial site to select a desired trial and contract conditions from the pre-registered trial information and contract conditions.  
         [0127]     Second Embodiment  
         [0128]      FIG. 26  is a block diagram showing the table area for storing the clinical trial contract support database in the second embodiment of the clinical trial contract support system of this invention.  
         [0129]     The reference numeral  2600  is an executable trial information storage area for storing information on a desired trial. The executable trial information storage  2600  is described using  FIG. 27 . Using this type of structure of course allows the clinical trial contract support system  440  of this invention to acquire information relating to the trial that the sponsors A, B wish to request. The trial sites a, b, c can also acquire and manage information relating to a desired trial.  
         [0130]     If the trial site registers the desired trial information and contract conditions in advance, then the above embodiment allows the trial site to select the best trial among those trials registered by the sponsor and establish a contract for that trial.  
         [0131]      FIG. 27  is a drawing of the table stored in the executable trial information storage area. The reference numeral  2700  is the executable trial information table stored in the executable trial information storage area  2600 ; reference numeral  2710  is an ID area for managing the primary key of the executable trial information table  2700 ; reference numeral  2711  is a trial site ID area for managing the foreign key to the trial site information table  620 ; reference numeral  2712  is a target disease name area for managing the desired target disease name by the trial site controlled in trial site ID area  2711 ; reference numeral  2713  is a phase area for managing the phase desired by the trial site; reference numeral  2714  is a trial length of trial area for managing the period of the trial desired by the trial site; reference numeral  2715  is a number of cases areas for managing the number of cases desired by the applicable trial site; reference numeral  2716  is a unit cost area for managing the case unit cost desired by the applicable trial site.  
         [0132]     The interface for registering information into the executable trial information table  2700  is described in detail using  FIG. 29 .  
         [0133]     By utilizing this type of structure, the clinical trial contract support system  440  of this invention can acquire and manage information relating to the desired trial from the trial sites, a, b, c. If the desired trial information and contract conditions are registered in advance, then the trial site can select and establish a contract for an ideal trial from among the trials registered by the sponsor, by managing the information as described above.  
         [0134]      FIG. 28  is a block diagram showing in detail the structure of the process and information service unit of the second embodiment of this invention. The reference numeral  2800  is a matching unit between contract condition and executable trials for referring to the contract condition information table  720  and the executable trial information table  2700 , and matching the information. The matching unit between contract conditions and executable trials  2800  starts up when contract confirmation processing was performed. The matching unit between contract condition and executable trials  2800  matches the information in the contract condition information table  720  with information in the executable trial information table  2700 , and extracts those trial sites that fulfill the contract conditions and registers that trial site information in the confirmed contract information table  800 .  
         [0135]     By including this type of unit, the trial site can match its pre-registered desired trial information and contract conditions, with the trial information and contract conditions registered by the sponsor, and therefore allow establishing a trial contract with ideal contract conditions for both the trial site and the sponsor.  
         [0136]      FIG. 29  is a drawing showing the interface for registering the executable trial information. The reference numeral  2900  is an executable trial registration interface for registering information into the executable trial information table  2700 ; reference numeral  2910  is a target disease entry area for entering the desired target disease name into the target disease area  2712 ; reference numeral  2920  is a phase entry area for entering the desired phase into the phase area  2713 ; reference numeral  2930  is a length of trial entry area for entering the desired trial period into the length of trial area  2714 ; reference numeral  2940  is a number of cases entry area for entering the desired number of cases into the number of cases area  2715 ; reference numeral  2950  is a unit cost entry area for entering the desired unit cost into the unit cost area  2716 ; and the reference numeral  2960  is a registration button for registering the above information into the clinical trial contract support database  420 .  
         [0137]     The trial sites a, b, c utilize the above interface to enter the information on the desired trial, and the information service unit  1000  registers the applicable information into the executable trial information table  2700  when the registration button  2960  is pressed. 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.  
         [0138]      FIG. 30  is a drawing showing the operation of the clinical trial contract support center of the second embodiment of this invention.  
         [0139]     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.  
         [0140]     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 .  
         [0141]     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.  
         [0142]     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.  
         [0143]     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.  
         [0144]     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.  
         [0145]      FIG. 31  is a flow chart showing in detail the procedure for confirming the contract in the second embodiment of this invention.  
         [0146]     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.  
         [0147]     The sponsors A, B view the subscribing trial sites entry area  1610  and decide if there are competing subscriptions from the trial sites subscribing to the contract trial site conditions (step  3130 ). If there are competing subscriptions, then the sponsors A, B depress the rival cancellation button  1620  (step  3140 ). When this rival cancellation button is depressed, the subscription rival calculation unit  1020  refers to the site rating information table  900 , eliminates competing trial sites (step  3150 ), 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  3160 ). If suitable then the sponsors A, B depress the confirmation button  1630  (step  3170 ). When the confirmation button  1630  is depressed, the information service unit  1000  registers the confirmed contract information in the confirmed contract information table  800  (step  3180 ), and the process terminates (step  3190 ).  
         [0148]     In step  3110 , if there is no registered executable trial information then the process terminates (step  3190 ). If there is no competition among subscribing trial sites in step  3130 , then the process proceeds to step  3160 .  
         [0149]     If the trial site registers the desired trial information and contract conditions and the sponsor also registers the requested trial information and trial conditions that the sponsor, then the clinical trial contract support system matches the applicable information so that a trial contract with ideal contract conditions is established. for both the trial site and the sponsor.  
         [0150]      FIG. 32  is a flow chart showing the detailed procedure for registering the contract in the second embodiment of this invention.  
         [0151]     When the contract subscription process  2450  is executed, the executable trial information registration interface  2900  appears as shown in  FIG. 29  (step  3200 ). The trial sites a, b, c utilize the executable trial information registration interface  2900  to enter information relating to the desired trial to execute (step  3210 ) and when the sites a, b, c depress the registration button  2960  (step  3220 ), the information service  1000  registers the desired trial to execute in the executable trial information table  2700 , and the process terminates (step  3230 ).  
         [0152]     If the trial sites register in advance the desired trial information and contract conditions, then this type of process allows the trial sites to select the best trial from among the trial registered by the sponsor and form a contract.
