What is Interactive Response Technology (IRT)?


IRT is an abbreviation for Interactive Response Technology. Another name that refers to IRT is “randomization and the management of trial supplies’. In essence, IRT helps clinical trial sites and sponsors manage the logistical needs of the patient and the supply of drugs during the course of a clinical trial. Due to its capacity to provide control and flexibility and increase efficiency, IRT has played an important function in helping biotechnology and pharmaceutical companies manage their data in order to reduce risk and cut down on costs and time in their clinical trials.

The initial development in IRT was the change from paper-based systems, to the management of transactions via phone

As I discussed What is Interactive Response Technology (IRT)? But we are going to give you complete detail.

IWRS (Interactive Web Response Systems):

The later IVR was internet-connected IVR first came out in the early 1990s. It operated in the same way however, the user had to respond to prompts via computers, not via phone. Modern systems are also able to connect with other technologies, meaning you can join your IWRS to your lab eligibility, for instance.

What are the main characteristics of an IRT?

Your IRT system can be utilized for a variety of functions in your trial, including:

Management of patients:

Through web or audio commands, users can register patients and keeps track of their visits to their website. Patients are also randomly assigned by an IRT and assigned to a treatment arm while keeping the identities of patients hidden. Your IRT will be programmed to use the trial’s own unique randomization algorithm.

The management of the supply chain:

The IWRS can also be utilized to manage the inventory of your study medication and dispense it to patients. Modern systems can manage complicated dispensing procedures and calculate dosage. Certain technologies also employ an algorithm that can predict the time you’ll run out on a drug in a study in relation to enrollment of patients and drop-out rate. Other technologies allow you to monitor the delivery while in transit and also monitor for temperature fluctuations that could harm the shipment.

Reporting and documentation:

Study managers can access automated system reports that provide real-time details about the trial.

Integration with different systems:

 If you are choosing the right vendor make sure you ask if their IWRS will work with your site’s current systems, like an existing clinical trial management software, Electronic Data Capture (EDC) system for recording clinical trial data, etc.

What will my IWRS look like? set up?

It usually required some time before an IVRS could be set up. Clients would usually write 200 to 300 pages of specifications for their system, which needed to be coded and checked, based on the past historical record of RTSM in Applied Clinical Trials.

With IWRS came the ability to configure systems that were configurable. Many trials are now created right straight out of the box, by selecting details about the trial’s treatment arms and dosing schedule, visit times, and more. Systems that can be configured allow you to configure your IRT for an upcoming trial with ease by changing the parameters for every trial. IWRS can also be utilized to conduct adaptive trials that are able to change as data arrives.

What can I do to ensure my IRT is in contact with other devices?

Integration is among the most crucial characteristics to be looking for when you are shopping for an IRT now. The past was when IRT platforms and electronic data capture (EDC) devices were distinct. The EDC system is the one statisticians utilize at the conclusion of a study to analyze data. Prior to integrating between the IRT and EDC data from the IRT required manual upload into the EDC.

Modern systems connect with EDC systems, which means there’s no longer any requirement for duplicate entries or reconciliation of data.

IRT systems

IRT systems also have the ability to connect to electronic patient-reported outcomes ( ePRO) technology. The patient’s information can be collected via phone, or via a website or application, based on the services offered by your specific vendor. When you first meet with potential partners, inquire which technologies are compatible with their products. If they also offer additional technologies that you’re in the market for, like Electronic Data Capture (EDC) and electronic patient-reported outcome (ePRO) having these from the same vendor allows for easy communication between them as well.

What do you feel that IWRS features changed over the past couple of years?

The majority of my experiences with technology were used for diaries of subjects. The subject would call in and utilize the system to respond to several questions. The system then recorded those entries in the database. As we moved to the web and the internet, users were able to perform more using the system. they could screen subjects as well as record the activities of the subject as well as randomize the subject -things like that and also monitor the shipments that came and went to the central warehouse.

 Effective And Superior Randomization:

You can also use more effective and superior randomization. For instance, for tiny studies, you can change the randomization to be dynamic instead of creating an orderly table where randomizations occur and the system uses an algorithm to decide the best method to ensure equilibrium between placebo and active drugs. These are all adjustable. No matter what dose levels you have you can control the dose at the level of the kit. As an instance, we did one study with 28 different kits of various dose levels included in every kit.

 The Advancements In Web Technology:

Today, thanks to the advancements in web technology, and the advancements in web and the technologies that support web technology, systems are able to utilize something called web services that let our systems connect to EDC and open the port. The data is transferred to the EDC like a person just sat down and recorded the information. The benefit of this is that people can log in to the IRT and take a screen for a person, the day of their birth perhaps their initials, or other important information needed at the time of screening, and then the IRT system will assign a number and send the data directly to EDC. After that, when the user logs off from the EDC system and then back to the IRT they will view the information that is already there and populated for the specific visit, and need not enter the specific data.

One of the most effective practices is to configure it to ensure that, within the EDC system, data transferred from the IRT isn’t editable, and therefore, it is impossible to access the EDC system to make changes to the data. If they are able to transfer the data into the IRT Then re-pushing the data back to the EDC removes the need for the user to input the data in both the EDC as well as the IRT system.

Do you know the features that people ought to be considering when they’re deciding on an IRT device?

Most of our customers seek the ability to configure, which is basically the ability to configure permits them to meet more ambitious timelines and be sure that the quality standards are achieved. Making sure that you have a flexible system is an important aspect of deciding the best IRT to pick.

Another thing I notice is the level of experience the team members have that you’ll work. I believe that the experience gained from using Best Practices, IRTs and IRTs, and applying that to the protocol of your sponsor is equally important.

Are there brand-new or intriguing new features that have appeared in the past couple of years?

There are definitely been. There are numerous things that IRT can now do that you wouldn’t normally expect to see. I’m thinking of things like direct-to-patient delivery that’s included in some protocols currently. The patients you treat have a condition that means they aren’t able to be able to attend a doctor’s appointment in person. There are now IRTs that can be used to aid in the trial design. Another example is adaptive trials, in which it is decided on the trial’s layout as information is received. These are important new aspects of the IRT which we’re experiencing. Another aspect that I believe is an emphasis these days is the more sophisticated clinical supply features that are part of an IRT, such as the ability to alter your strategies for resupply in real-time, and interacting with the parameters involved in the prediction of supply. IRT generally, I believe today more than any time has become an integral part of the overall clinical trials environment. There is a growing demand for data integration and exchange of clinical trial data among IRT and other systems.

The use of Interactive Response TechnologyWhat is Interactive Response Technology (IRT)?


Patient Management

The protocol outlines the process of how it is designed and we can implement

. The type of study determines the type of treatments the patients will be receiving, whether it’s or not the Investigational Product (IP) or the comparator (existing medication referred to as the standard of care or placebo in the event that there isn’t a treatment for the illness).

The IRT system handles assigning patients to specific treatment regimens to ensure they are receiving the appropriate drug or combination of drugs or placebo, based on the treatment arm. It assists sites in scheduling appointments for patients from the beginning of screening to the conclusion of treatment. IRT can also help maintain the illusion of blindness by ensuring that the specific people involved in a study (e.g. the clinical research coordinators) are not aware of the type of treatment patients are receiving.


Drug Supply Management

IRT can allow medical supply officers to make calls for the delivery of their supplies to the sites and it can also trigger automatic deliveries from depots to the sites.

Once the shipment arrives at clinical sites When they reach clinical sites, the IRT aids sponsors and sites control inventory at the site. This allows for the optimization of the number of kits of drugs available at each site in order to meet the enrollment at each of the sites and also trigger automatic delivery or notify suppliers of drugs when they are short of supplies.

IRT is an accountability mechanism:

It is also possible to use the IRT system of the present can also manage protocols that have complex dosage regimens that alter according to the protocol’s needs. For example, an IRT system could calculate dosage levels based on the weight of the patient. It could achieve this by integrating an Electronic Data Capture (EDC) system

.for Reporting and Analysis

In storing and arranging patient and supply information, IRT is also an essential tool to analyze the efficiency of a research study across all its locations so that study teams can maximize the conduct of their trials.
