Don’t Make These Mistakes at the End of Your Trial

The following mistakes are commonly seen during clinical trial close out, leading to inefficient project management and delays in regulatory submissions:

  1. Inadequate Documentation: Failing to maintain comprehensive records and documents, which can lead to regulatory issues and data gaps.
  1. Incomplete Data Analysis: Neglecting thorough data analysis, potentially missing crucial insights.
  1. Inaccurate Reporting: Errors or omissions in final reports can compromise the validity of study outcomes.
  1. Regulatory Non-Compliance: Overlooking regulatory requirements during closeout, leading to regulatory scrutiny or delays.
  1. Budgetary Oversights: Underestimating the costs associated with closeout activities.
  1. Timeliness: Not adhering to planned timelines, causing unnecessary delays.
  1. Ineffective Communication: Poor communication with trial sites and investigators can hinder the closeout process.
  1. Data Security: Failing to adequately protect and archive sensitive trial data.
  1. Insufficient Training: Inadequately trained staff involved in closeout tasks can lead to errors.
  1. Lack of Contingency Planning: Not preparing for unexpected issues that may arise during closeout.

Avoiding these mistakes requires careful planning, attention to detail, adherence to regulatory guidelines, and effective communication among all stakeholders involved in the clinical trial closeout process.

Need to Store Liver Biopsy Specimens at the End of a NASH Trial?


Specialized freezers and cryopreservation techniques allow samples to be preserved at very low temperatures, ensuring long term stability. Stringent security and tracking systems maintain the integrity of stored samples long after clinical trial close out.

Formalin-Fixed Paraffin-Embedded (FFPE) Blocks

FFPE allows for long term storage of tissue samples at room temperature. This method is perfect if you are planning for future histopathological examinations, immunohistochemistry, or molecular studies.

Frequently Asked Questions

Now that you’ve completed your trial, a trusted expert can help you complete the process. Here are answers to some common questions about essential clinical trial close out activities.

To end a clinical trial, the sponsor or principal investigator follows predefined protocols: data analysis, regulatory reporting, closeout site activities, and final documentation for regulatory submission.

The sponsor is primarily responsible for orchestrating the clinical trial close out activities and regulatory compliance. Working with a strong CRO can provide guidance to help ensure the sponsor meets all requirements.

A clinical trial can be terminated prematurely due to various factors, such as safety concerns, lack of efficacy, protocol violations, or sponsor decisions.

After a clinical trial is completed, data analysis, regulatory reporting, and closeout activities occur. Successful trials may proceed to regulatory submission and, if approved, market launch.
