Expanded Access Policy

AlloVir is committed to developing safe and effective therapies addressing severe and potentially life-threatening virus-associated diseases and their potential sequalae. Our goal is to provide access to our investigational therapies at the appropriate time and in the correct manner for patients. 

Expanded access refers to the use of an investigational therapy outside a clinical trial when the primary purpose is to diagnose, prevent, or treat a serious condition in a patient. This is different from a clinical trial, where more comprehensive safety and efficacy data are collected. We understand the need for expanded access programs, and we recognize the importance of having an appropriate policy.

A number of factors consistent with the US Food and Drug Administration (US FDA) and other regulatory agencies’ guidelines should be taken into account when considering expanded access. They include:

  • The illness must be serious or immediately life-threatening with no other satisfactory treatment options (such as approved products or enrolling clinical trials).

  • The patient must have undergone appropriate standard treatments without success and no comparable or satisfactory alternative treatment is available or exists to treat the disease or condition.

  • The patient is ineligible for participation in any ongoing clinical study of the investigational product, which includes lack of access due to geographic limitations.

  • The patient has a disease for which there is sufficient evidence of a projected benefit from the use of the investigational product and the benefit outweighs the known or anticipated risks.

  • There is an ability to provide the product in a fair and equitable manner and there is adequate manufacturing capacity for ongoing programs.

  • Whether granting expanded access would potentially compromise the scientific validity of broader development programs or interfere with or delay current clinical trials or regulatory filings designed to make the therapy available to many more patients.


At this time, AlloVir believes that participation in one of our clinical trials is the most appropriate way to access our investigational therapies. If you have additional questions, please speak with your physician or contact expandedaccess@allovir.com. We anticipate acknowledging receipt of requests sent to this email within five business days.
