Individual Compassionate Use Policy for the United States and Canada

At ACADIA Pharmaceuticals Inc. (ACADIA), we are passionate about improving the lives of patients with central nervous system disorders. ACADIA is committed to bringing safe and effective treatments to patients by conducting rigorous clinical trials and obtaining regulatory approval for marketing by regulatory agencies. Before new treatments can be made publically available, the United States (U.S.) Food and Drug Administration (FDA) and other regulatory agencies around the world require that investigational medicine(s) are studied in clinical trials.

Clinical trials are the most appropriate way for patients to access investigational medicines being developed by ACADIA. In these trials, the safety and efficacy of investigational medicines is rigorously assessed by ACADIA and the appropriate regulatory agencies in order to understand the medicine’s benefits, risks, and appropriate use, including whether or not it should be approved as an appropriate therapy for the patients’ medical or mental condition. Obtaining regulatory approval is the only way to bring access of a medicine to the greatest number of patients who may benefit from

We understand that there may be some individual patients who do not qualify to participate in an ongoing ACADIA clinical trial, but have serious or life-threatening conditions and have exhausted all available medical options. For these individual patients, when it is allowed by applicable law and meets ACADIA’s Individual Compassionate Use criteria, ACADIA may provide physician requested and managed access to investigational medicine through an Expanded Access Program in the U.S. or through a Special Access Programme in Canada, collectively referred herein as “Individual Compassionate Use”.

Criteria for Considering Requests for Individual Compassionate Use

On a case by case basis, ACADIA considers requests from U.S. and Canadian licensed physicians for access to the investigational medicine for patients who have serious or life-threatening diseases or conditions for which there is no comparable or satisfactory alternative therapy. Specifically, these patients include:

  • In the U.S., patients who have a diagnosis of hallucinations and/or delusions associated with dementia; or patients who have schizophrenia symptoms that have not adequately responded to a single antipsychotic medication.
  • In Canada, patients who have a diagnosis of hallucinations and/or delusions associated with Parkinson’s disease psychosis.

There are a number of factors that ACADIA may consider upon receiving and evaluating a request for Individual Compassionate Use. These factors include:

  • The patient seeking treatment has a serious or life threatening disease or condition, and no alternative therapies to treat the disease or condition are available.
  • The physician believes the potential benefits of the investigational medicine will outweigh any potential risks to the patient, as described in the United States Prescribing Information (USPI).
  • The physician provides sufficient data to make an assessment of the benefit and risk of the proposed use of the investigational medicine for the patient’s serious or life-threatening disease or condition.
  • All necessary regulatory/institutional approvals have been obtained to allow administration of the investigational medicine.
  • The patient is ineligible to participate in a clinical trial or there is no such ongoing clinical trial for this serious or life-threatening disease or condition.
  • All other important criteria established by the medical experts at ACADIA.

ACADIA does not guarantee access to investigational medicine for a particular patient. Any access to investigational medicine for Individual Compassionate Use is subject to local/national laws and regulations and must also comply with any applicable country-specific laws and regulations, including drug importation and distribution requirements. Approvals from applicable regulatory agencies and by an Institutional Review Board or Ethics Committee from the treating institution must be obtained prior to each Individual Compassionate Use. If approved, the patient (or his/her legal guardian/caregiver) must provide written confirmation of informed consent and both the patient and his/her treating physician must agree to comply with ACADIA’s safety and monitoring and reporting requirements prior to receiving access to the investigational medicine for Individual Compassionate Use.
