The regulations that regulate device research, in vitro diagnostics (IVDs), and digital treatments differ from those that control pharmaceutical development. While pharmaceuticals need Phase I-III clinical trials and post-approval monitoring, digital therapies, devices, and IVDs may be able to benefit from bench testing, animal studies, pilot studies, and training sets. These are frequently followed by validation studies, pivotal trials, literature reviews, and even real-world evidence studies, depending on the intended purpose and risk level of the unique product.

Medical devices, IVDs, and digital therapies have the potential to provide major health advantages to patients of all ages, including those who are well and those who have varied degrees of health illnesses and disease burdens. Interpreting changing rules for these devices is frequently a one-of-a-kind issue for young biotech enterprises. Even for well-established life science organizations, staying on top of new regulatory requirements for a complicated medical device category may be difficult.

How can you know whether your device needs clinical ...
... trials? Here are several approaches to determining if clinical trials are required and navigating the compliance complexities of the medical device category.

1.Function Dictates Regulation

It's critical to understand how the product interacts with a patient and how important it is to the patient's health. In other words, what are the product's dangers and benefits? The greater the risk, the more probable it is that a set of studies will be necessary for market clearance or approval.

A medical device, IVD, or digital therapeutic is classified as one of the following in the United States:

Class 1: Non-invasive, minimal patient risk, and subject solely to "general controls" on registration, branding, and labeling such as an ePRO device.

Class 2: items that pose a higher danger to the patient; most items in this group require a 501(k) premarket notice, which includes a comprehensive comparison to an existing device.

Class 3: Used for the most dangerous items, or Class 2 products that are the first in their category. These items will require clinical trial data to be brought to market but with many fewer participants than a medication study.

2.Intended Use, Indication, and Mode of Action

Intended usage and signal for use are frequently misconstrued or misunderstood. Consider the intended usage's intent or purpose (e.g., what the device performs) and the indication for use (patient population, ailment, condition, and length of use). Consider the target consumers as well as the usage environment. These are the claims made on the product labeling and must be effectively substantiated in clinical proof.

Consider the following scenarios to help you decide your path: a tiny camera that the patient swallows to take internal photographs, a novel blood test designed to detect monkeypox or a mobile device application that monitors a patient's A1C levels.

The indication follows the intended usage, but it also contextualizes the product within the framework of a disease/medical condition. It's vital to remember that the indication might modify the risk level of the medicine. In the preceding example, the camera detects intestinal issues, the blood test detects a possible infection, and the mobile medical app (MMA) assists patients with diabetes types 1 and 2.

Finally, what is the product's mechanism of action (MoA), particularly as it pertains to patient interactions?

It is critical to consider if the product is intrusive or non-invasive, whether it poses a big or little danger, and whether it operates within or outside of the patient. This is how the product works to be therapeutic. A harmonic scalpel, for example, vibrates as it cuts, a COVID-19 test detects SARS-CoV-2 antibodies by measuring antigens in a person's saliva/mucus, and a digital therapeutic program electronically signals when a patient should follow best practices or engage in a positive-reinforced behavior.

3.Gather and Publish the Evidence

A thorough clinical evidence generation plan specifies what important data is required as proof that the product achieves what it is designed to do safely. To secure product clearance in some markets, particularly the EU, publishing may be required.

The most important aspect is determining what type of study to perform. Return to the type of product and its risk level to determine whether a trial is necessary, and if so, what kind. Trial types include:

Pilot or feasibility study: a tiny study that collects safety data, validates an idea and can inform future research design.

Verification studies (training set): minor studies conducted prior to the design freeze to test a device or train an algorithm.

Validation Studies: Validation studies are bigger studies aiming to back up the stated efficacy and safety - or sensitivity and specificity - of certain devices and/or algorithms.

Demonstration of Equivalence: EU distinction for literature and other comparison evidence against the performance of an existing product

In Silico: Studies aimed to mimic data without human testing.

Efficacy Validation: Large, statistically driven research to validate efficacy, safety, and risk-benefit analysis.

RWE: Real-world evidence (RWE) is data gathered from real-world sources such as registries, electronic health records, administrative claims, and so on.

Post-market Safety: Post-market safety is typically used to justify responsibilities imposed after clearance or approval.

Human factors: to inform end users about ease of use, features, labeling, and directions.

In Summation
It is difficult to define appropriate outcomes for clinical studies on medical devices. This is due in part to the wide range of complexity and uses for many types of medical equipment, such as pacemakers, insulin pumps, operating room monitors, defibrillators, and surgical tools, and in part to the wide range of potentially relevant outcomes.

A special impediment in the medical device sector is the lack of a clear understanding of the idea of outcomes. Traditional outcomes such as survival, complication rates, or surrogates (biomarkers, imaging techniques, and omics) are used in clinical trials with medical devices rather than more appropriate hermeneutic outcome measures such as quality of life, autonomy, discomfort, disability, and life satisfaction.

When non-significant test findings are obtained, trials on medical equipment supported by industry are more likely to declare good outcomes and to conclude in favor of experimental therapies. While industry cooperation is required to enhance technology and promote MD innovation, it must be scientifically sound and completely transparent.

This may appear to be a hard issue, but if you break it down by device lifecycle stage and kind of clinical activity, you'll have a plan for how you'll acquire the clinical data you need for your device.

It therefore goes without saying that when it comes time to gather that data, you'll need a versatile, contemporary platform that can expedite data collection from all of your clinical operations.

Octalsoft is the platform in question. Our EDC for medical devices allows you to capture and manage data in clinical trials, performance studies, PMCF/PMPF studies, surveys, registries, cohorts, or case series with simplicity. Want to learn more? Contact us today to schedule a personalized demo!
