Investigator Sponsored Research

Astellas and its alliance partners are committed to supporting investigator sponsored research studies that promote the advancement of medical and scientific knowledge and innovation involving Astellas products and therapeutic areas of interest.

What is Investigator Sponsored Research?
Investigator Sponsored Research (ISR) is proposed by a Sponsor-Investigator or institution for which support is requested to obtain an Astellas compound, and/or funding to perform specific research. The Investigator assumes full responsibilities for the research/study as the Sponsor.

Investigator Sponsored Research Overview:
Sponsor-Investigator or institution proposing the research can be an investigator, physician, non-clinical researcher, clinical research group, consortia and/or Cooperative Group. ISRs include, but are not limited to, non-clinical or clinical research, including epidemiological, non-interventional (e.g., registries) and interventional studies. Requests for support for a specific independent study with treatment and/or analysis according to a protocol must be classified as an ISR.

ISR proposals must be submitted independently (no influence by Astellas) through the ISR submission portal and reviewed by Astellas medical and scientific committees. The decisions of the committees are based upon scientific merit, alignment with research areas of interest, and availability of resources.

The areas of interest may provide Investigators with additional knowledge about open ISR programs to see whether their research proposal and expertise fits with recognized priorities. Astellas is interested in supporting studies that are innovative and contribute to scientific knowledge of a product, a disease state, medical condition or advancing technology. The areas of interest are to serve as a guidance for submission of a proposal and does not guarantee Astellas support.

Please refer to the table below for the areas of interest supported by Astellas.
