PharmaTher Receives Complete Response Letter from the U.S. Food and Drug Administration for Ketamine Abbreviated New Drug Application

TORONTO, Oct. 23, 2024 (GLOBE NEWSWIRE) -- PharmaTher Holdings Ltd. (the “Company” or “PharmaTher”) (OTCQB: PHRRF) (CSE: PHRM), a specialty pharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has issued a complete response letter (CRL), dated October 22, 2024, for the ketamine Abbreviated New Drug Application, which was assigned a Generic Drug User Fee Amendments of 2022 (“GDUFA”) goal date of October 29, 2024.

The deficiencies cited in the CRL are classified as MINOR. The FDA requested new and updated information and clarifications related to drug substance, drug product, manufacturing, and microbiology. The FDA did not express concern about the stability of the ketamine submission batches, which achieved 18 months of stability without issue, and no new preclinical and clinical studies were requested.

As noted by the FDA in the CRL, the resubmission to this CRL will be considered to represent a MINOR AMENDMENT, given that the deficiencies have been classified as MINOR. The Company will be working with its third-party manufacturing partner to resolve these deficiencies and respond to the FDA in a timely fashion. The Company will provide a timeline for responding to the FDA as soon as possible and continue to provide updates as they occur.

The Company is committed to its overall goal to solve the ketamine shortage problem in the U.S. and to adhere to the FDA’s strict manufacturing guidelines and FDA-approved prescribing label. Ketamine has been on the FDA’s drug shortage list since February 2018, which is believed to have encouraged the widespread availability of compounded ketamine products not FDA approved for psychiatric disorders. On October 10, 2023, the FDA published a compounding risk alert describing the potential risks associated with compounded ketamine products for psychiatric disorders, specifically from telehealth providers that provide in-home ketamine services. These compounded ketamine products are not FDA approved. 

Ketamine is an essential medicine used for anesthesia and analgesia (pain relief) listed on the WHO Essential Medicines List. Health Canada has approved ketamine for use as a sedative and painkiller in hospital settings. Outside of the FDA and Health Canada approved indications, ketamine is also being administered in hospitals and clinics to treat various mental health, neurological and pain disorders. A recently published new peer-reviewed study on the real-world effectiveness of ketamine intravenous therapy demonstrated significant patient improvement for depression, anxiety and suicidal ideation.
