Clinical Trial Registration

Gilead registers clinical trials on clinical trial registries such as ClinicalTrials.gov (CTgov) and EudraCT (EU-CTR) as required by law and/or regulation, and in accordance with local requirements.

In cell therapy, we are currently investigating multiple indications in the axicabtagene ciloleucel and the KTE-C19 development program as well as for our TCR pipeline and second-generation technology. Our areas of research include a variety of blood cancers and solid tumors.

These cell therapy clinical trials can be viewed on our pipeline page, as well as ClinicalTrials.gov.

Gilead ensures that applicable clinical trials are registered prior to the first patient being consented for the study. Registration prior to first patient consent is aligned with the International Committee of Medical Journal Editors (ICMJE) guidelines.


Posting of Clinical Trial Results

Gilead discloses summary clinical trial results, regardless of the outcome of the trial, as required by law and/or regulation. This includes Gilead-sponsored clinical trials that have been registered on publicly accessible clinical trial registries.

In the USA, summary results are posted on ClinicalTrials.gov (CTgov) no later than 12 months after the study’s primary completion date for all Gilead sponsored studies related to an approved product. A full definition of primary completion date can be found in the ClinicalTrials.gov study glossary.

  • For studies with a primary completion date prior to January 18, 2017 and related to products that have not yet been approved or are being investigated for new uses, Gilead posts summary results on ClinicalTrials.gov (CTgov) within 30 days of receiving regulatory approval. For studies with a primary completion date after January 18, 2017 and related to products that have not yet been approved or are being investigated for new uses, Gilead posts summary results within 12 months of primary completion date regardless of approval status.

In Europe (EU and EEA), summary results are posted on the European Union Clinical Trial Register (EU-CTR) no later than 12 months after the trial Last Patient Last Visit Date (LPLV) for trials with adult participants and no later than six months after the trial LPLV Date for trials with pediatric participants regardless of approval status.

In Countries outside the US and the EU, Gilead adheres to all mandatory results posting requirements in accordance with the country specific guidelines for that region.
