Teglutik Prescribing Information

Important Prescribing Information

January 2024

Subject: Temporary importation of TEGLUTIK (riluzole oral suspension, 5 mg/mL) with non-English labeling to address drug shortage in the United States

Dear Health Care Provider,

The purpose of this letter is to inform you about a temporary importation in the United States (U.S.) of TEGLUTIK (riluzole 5 mg/mL oral suspension) with bottle and carton labels in Spanish, in coordination with the U.S. Food and Drug Administration (FDA) to mitigate the current shortage of FDA-approved Tiglutik (riluzole oral suspension, 50 mg/10 mL) in the U.S. This temporary supply of TEGLUTIK is marketed and manufactured by Italfarmaco in Spain and is not FDA-approved.

Riluzole is indicated for the treatment of amyotrophic lateral sclerosis (ALS). Recently, Tiglutik was recalled in the U.S. market due to an out-of-specification test result for viscosity.

At this time, no other entity except EDW Pharma, Inc. (formerly Italfarmaco (ITF) Pharma, Inc.) is authorized by the FDA to import or distribute Italfarmaco's TEGLUTIK riluzole oral suspension in the U.S.

Effective immediately, and during this temporary period, EDW Pharma, Inc. will distribute the following presentation of riluzole oral suspension to address the critical shortage:

The safety profiles of the FDA-approved Tiglutik and imported TEGLUTIK products are

comparable and no specific safety concerns emerged from the comparison of the two products.

Please refer to the side-by-side comparison of the labels (enclosed) for additional information.

It is important to note that the enclosed side-by-side comparisons, in English, between the U.S. product information and the European product information including the labels, patient leaflet, and SmPC (Summary of Product Characteristics, equivalent to the U.S. Prescribing Information (USPI)) have been included to also provide all applicable information since the labels and leaflet with the imported product are in Spanish.

Tiglutik is available only by prescription in the U.S. The imported lot does not have the statement "Rx only" on its labeling.

The barcode on the imported product label may not register accurately on the U.S. scanning systems. Institutions should manually input the imported product information into their systems and confirm that the barcode, if scanned, provides correct information. Alternative procedures should be followed to assure that the correct drug product is being used and administered to individual patients.

In addition, the package of the imported product does not include a product identifier as required under the Drug Supply Chain Security Act (DSCSA). Specifically, each package does not include the NDC, unique serial number, lot number, and expiration date in both human- readable and a two-dimensional data matrix barcode. Additionally, the imported product may not be accompanied with DSCSA-required product tracing documentation (transaction information, transaction history, and transaction statement).
