Healthcare Providers

At Sage, we are thinking differently about drug development. We aim to transform the practice of neuroscience research and rethink how brain health disorders are understood and treated.

Sage Medical Hub

The Sage Medical Hub is a resource for licensed HCPs and other key stakeholders that provides access to Sage’s Global Medical Affairs team.

Visitors to the hub may:

  • Submit Medical Information Requests for accurate and timely medical information
  • Request a call from an MSL
  • Learn about Sage’s funding and giving efforts and submit a grant or sponsorship request
  • View information on Sage’s clinical trials and pipeline

Restoring Normal Balance to the Brain

Modulating GABA and NMDA Receptors

We focus our research and development efforts on modulation of GABA and NMDA receptors—two critical neurotransmitter systems in the brain. The GABA system is the major inhibitory signaling pathway of the brain and central nervous system (CNS); NMDA is the major excitatory pathway. Both contribute significantly to regulating CNS function. Dysfunction in these two systems is known to be at the core of numerous psychiatric and neurological disorders. Our novel investigational compounds are intended to alter activity at these receptors by working with the brain’s natural signaling mechanisms. We believe compounds that are designed to restore normal balance between excitatory and inhibitory signals within the brain have the potential to treat a range of brain health disorders associated with a variety of cognitive, neurological, and behavioral symptoms.

Clinical Trials

We’re conducting clinical trials in several brain health disorders where there is a need for additional treatment options.

Expanded Access Program

Sage is committed to discovering, developing and commercializing novel medicines to transform the lives of patients with life-altering brain health disorders. As part of this mission, we conduct clinical trials to determine if our investigational medicines are safe and effective for patients with a particular disease, disorder or condition which may allow us to seek the necessary regulatory approvals to provide wide access to these medicines.

We understand that, in some cases, patients with serious diseases or conditions may not be eligible for clinical trials and may not have other treatment options. Under very limited circumstances, we will consider making investigational medicines available for individual patients to treat a serious disease or condition outside of a clinical trial. This type of access is often referred to as “expanded access” or “compassionate use”. The following criteria must typically be met before we will consider making one of our investigational medicines available to individuals under an expanded access program:

  • The patient has a serious disease or condition, has exhausted all available treatment options, and is not eligible for any appropriate clinical trials.
  • The investigational medicine is currently being studied, or has been studied, in clinical trials for the treatment of a disease or condition that is similar in type and stage to the indication for which the expanded access is sought.
  • The request is made by a licensed physician who is qualified and knowledgeable in the treatment of the relevant disease or condition. Patients who are interested in understanding access options should speak with the physician overseeing their care.
  • There is sufficient evidence that the potential benefit to the patient, taking into account available safety and efficacy information, would likely outweigh the potential risks to the patient.
  • Adequate clinical data exist to support the appropriate dose amount and frequency of the investigational medicine and duration of treatment in the relevant disease or condition.
  • There are adequate supplies of the investigational medicine to meet the needs of the expanded access program without impairing ongoing development, including ongoing and planned clinical trials.
  • The requested use will not have the potential for a negative impact on broader development programs, including ongoing or planned clinical trials or regulatory filings designed to make the therapy available to many more patients.
  • The proposed use will occur in a country where we plan to seek approval of the investigational medicine.
  • The requested use complies with applicable laws and regulations.

Treating physicians should submit expanded access requests on behalf of patients to Sage at Please do not include a patient’s personally identifiable information in any request. Requests are assessed, on a case-by-case basis, by a team at Sage that includes medical professionals who are familiar with the data collected on the investigational medicine. In evaluating a request for expanded access, we may consider all relevant factors not just those specified above, including other factors relevant to patient safety. We anticipate acknowledging receipt of requests within five business days. If required, the regulatory agency in the relevant country must also approve the proposed use of the investigational medicine. The requesting physician must agree to obtain appropriate regulatory and ethics committee approvals, if applicable, and to comply with all other safety, monitoring, and patient consent requirements.

If a request is granted, expanded access will be discontinued as soon as feasible when approval of the drug is achieved in the country, subject to any legal or regulatory requirements.

In some cases, we may set up a program designed to provide access to a number of patients. We plan to fulfill applicable obligations to include information related to our expanded access activities on or other applicable registries.

We may revise this policy at any time consistent with applicable law and regulations.
