Investigational Medicines for Compassionate Use Requests

Investigational Medicines for Pre-Approval Access Requests (also known as Compassionate Use)

At Janssen, we are often asked how patients with serious diseases may potentially obtain medicines under development and not yet approved by government health authorities (investigational medicines).  “Pre-approval access” is the term used by Janssen for any access to an investigational medicine prior to its approval. Other terms used to describe pre-approval access include “compassionate use”, “named patient programs” or, “expanded access”.

The preferred and primary pathway for access to Janssen’s investigational medicines is to enroll in a clinical trial. Information about ongoing Janssen clinical trials can be found at Janssen Global Trial Finder. Additional information about ongoing clinical trials outside of Janssen can be found on these sites (please note this list may not be exhaustive): United States, European Union, United Kingdom, Australia/New Zealand, China, Japan, Brazil, and Africa.

If a clinical trial is not an option, a patient’s treating physician may submit an individual request for pre-approval access for an investigational medicine. Janssen reviews each request and makes decisions by evaluating factors that include but are not limited to:

  • The patient has a serious or life-threatening disease or condition
  • The patient is not eligible or cannot participate in a clinical trial
  • No alternative therapies are available, or the patient’s disease has exhausted all available therapies
  • Potential benefits of the investigational treatment outweigh the potential risks
  • Country/Territory laws and regulations
  • Availability of medication supply

Please note that only treating physicians may submit a request but that does not guarantee that access will be granted.

The investigational medicines in the table below are currently potential options for eligible patients. Treating physicians who wish to submit a request may do so by registering on the Janssen Managed Access Portal (MacWeb). Janssen commits to providing an answer within 5-10 business days, assuming all required medical information has been submitted.
