What are the requirements for registering clinical trials in the USA?

Registering clinical trials in the USA is an important step in ensuring transparency and accessibility of clinical trial information. The primary platform for registering clinical trials in the United States is ClinicalTrials.gov, which is maintained by the National Library of Medicine (NLM) at the National Institutes of Health (NIH).

Here are the key requirements for registering clinical trials in the USA:

Applicability

ClinicalTrials.gov registration is required for most interventional clinical trials of drugs, biologics, and devices that are subject to U.S. Food and Drug Administration (FDA) regulations. This includes Phase 2, Phase 3, and Phase 4 clinical trials. Trials that do not fall under FDA regulations, such as certain Phase 1 trials and observational studies, may not be subject to mandatory registration.

Responsible Party

The responsible party, typically the sponsor or principal investigator (PI), is responsible for registering the clinical trial on ClinicalTrials.gov. The responsible party must provide accurate and up-to-date information about the trial.

Timing of Registration:

Sponsors or researchers must register for clinical trials on ClinicalTrials.gov no later than 21 days after enrolling the first participant. Trials that were initiated before September 27, 2007, but are ongoing, are also subject to registration requirements.

Required Information

The following information is required when registering a clinical trial on ClinicalTrials.gov:

• Study title
• Study design (e.g., randomized, non-randomized)

For which types of products can sponsors exempt clinical trials?

Sponsors typically conduct clinical trials to assess the safety and efficacy of new medical products, including drugs, biologics, and medical devices, before gaining approval for patient use. However, there are certain situations and products for which clinical trials may be skipped or reduced in scope. Here are some examples:

• Drug Repurposing: When considering the use of an existing drug, which has already received approval for one indication, in another condition, sponsors may reduce or skip clinical trials if there is sufficient safety and efficacy data available for the approved use, and the new use is well-established.
• Medical Devices with Substantial Equivalence: The relevant regulatory authority (e.g., the FDA in the USA) may exempt some medical devices from full clinical trials if they consider them substantially equivalent to a device that is already approved or cleared. In such cases, manufacturers can seek clearance through the 510(k) pathway (USA) or similar pathways in other countries.
• Certain Biologics and Biosimilars: Biosimilars, which are highly similar to approved biologics, may require less extensive clinical testing compared to the original biologics. Regulatory authorities may consider the totality of evidence, including analytical, nonclinical, and clinical data, to determine the need for clinical trials.
• Orphan Drugs: Orphan drugs are designed to treat rare diseases or conditions. Regulatory agencies may provide flexibility in the clinical trial requirements for orphan drugs due to the limited patient population.
• Post-Market Studies and Surveillance: Regulatory authorities may approve some products, such as medical devices or drugs, with the condition that they conduct post-market studies or surveillance to monitor long-term safety and efficacy. These studies are considered part of the approval process.
• Emergency Use Authorization (EUA): In emergencies, such as pandemics, regulatory authorities may grant EUAs to allow the use of certain medical products, like vaccines or treatments, without full clinical trials. However, rigorous safety monitoring and data collection are typically required in such cases.
• Generics: Generic drugs, which are copies of brand-name drugs with the same active ingredients, typically do not require full clinical trials to establish safety and efficacy. Instead, they rely on bioequivalence studies to demonstrate that they perform similarly to the reference product.

It’s important to note that even in cases where clinical trials may be reduced or skipped, safety and efficacy data are still crucial. Regulatory authorities will assess the available evidence and make determinations based on the specific circumstances and regulatory pathways applicable to the product.

Additionally, ethical and patient safety considerations are paramount in all medical product development and approval processes.

What is the import process for clinical trial ancillaries and IMPs for clinical trials in the USA?

The import process for clinical trial ancillaries (items used in support of the clinical trial, such as medical devices or equipment) and investigational medicinal products (IMPs, which are experimental drugs or biologics) in the USA involves several steps and adherence to regulatory requirements.
