Drug development is a complex, multi-phase process, involving rigorous testing to ensure safety and efficacy. Prior to drug or biologic testing in human subjects, approval must be obtained from regulatory authorities like the United States (US) Food and Drug Administration (FDA) if the drug or biologic is to be marketed in the US and Health Canada if Canada is the market of interest. In the US, approval is obtained through an Investigational New Drug (IND) application, while in Canada, the application required is a Clinical Trial Application (CTA).

The IND / CTA provides comprehensive information about the investigational product, including its composition, manufacturing process, preclinical data, and proposed clinical trial protocol. Compliance with regulations and guidelines ensures the drug development process meets the established safety and efficacy standards, which increases public trust in the eventual marketed product. IND / CTA submissions allow pharmaceutical companies to engage with key stakeholders such as regulatory authorities, healthcare providers, patient advocacy groups, and academic institutions. This engagement fosters collaboration and transparency throughout the drug’s development period and lifetime on the market.

The regulatory agencies review the IND / CTA application to assess safety of the clinical trial proposed. The review includes preclinical data evaluation in the form of animal studies to identify potential risks to human participants and assessment of the measures in place to protect participants’ rights and well-being. Early dialogue with the regulatory agency is of significant benefit to the drug development process by addressing regulatory questions and study design considerations, aligning data requirements, and fostering collaboration and transparency throughout the developmental process. IND / CTA review and approval adhere to the international standards established by organizations like the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH). Aligning with international standards enhances the credibility of clinical trial data generated, supporting regulatory submissions to other global health authorities, including the European Medicines Agency (EMA) and Asia-Pacific regional agencies.

Approval of an IND / CTA allows clinical studies to proceed under a regulator’s oversight, ensuring the trial is conducted as per the approved protocols, meets ethical and regulatory standards, and the safety of participants is prioritized. Clinical trials conducted under an approved IND / CTA generate valuable data on the safety and efficacy of the investigational product, which is essential for obtaining regulatory approval and eventual marketing authorization.

IND / CTA authorization signals regulatory validation of the safety profile and development plan of the investigational drug, boosting investor confidence and attracting potential partners or collaborators. Pharmaceutical companies can use IND status to negotiate licensing agreements, co-development partnerships, or funding arrangements with other industry players, academic institutions, or government agencies.

To summarize, IND / CTA applications are critical components of the drug development strategy, serving as regulatory gateways to human clinical trials and ensuring the safety and efficacy of new drugs or biologics. By strategically managing these applications, companies can mitigate risks and enhance efficiency of the drug development process, ultimately bringing safe and effective new treatments to patients.
