Subject: Temporary importation of Potassium Chloride Proamp® 0.15 g/mL (equivalent to 2 mEq/mL), concentrate for solution for infusion to address drug shortage

June, 2018

Dear Healthcare Professional,

Due to the critical shortage of Potassium Chloride for Injection Concentrate 2 mEq/mL, USP in the United States (U.S.) market, Laboratoire Aguettant (Aguettant) is coordinating with the U.S. Food and Drug Administration (FDA) to increase the availability of Potassium Chloride for Injection. Aguettant has initiated temporary importation of its Potassium Chloride Proamp® 0.15 g/mL (equivalent to 2 mEq/mL) concentrate for solution for infusion. This product is manufactured and marketed in France by Aguettant.

Given the scale of this shortage, FDA is coordinating with several firms to import Potassium Chloride for Injection 2 mEq/mL. At this time, however, no other entity except La Jolla Pharmaceutical Company is authorized by the FDA to import or distribute Aguettant's Potassium Chloride Proamp® 0.15 g/mL (equivalent to 2 mEq/mL) concentrate for solution for infusion. FDA has not approved Aguettant's Potassium Chloride Proamp® 0.15 g/mL concentrate for solution for infusion, but allows its temporary importation into the United States. You may be provided with additional letters for other imported products you receive. Please read each letter in its entirety because each letter may contain different, product-specific information.

Effective immediately, and during this temporary period, Aguettant will offer the following presentation of Potassium Chloride for Injection:

There are key differences between the labeling of the FDA approved Potassium Chloride for Injection 2 mEq/mL products and Aguettant's imported Potassium Chloride Proamp^® 0.15 g/mL.

It is important to note the following:

• Aguettant's product is labeled Potassium Chloride Proamp® 0,15 g/mL which means 0.15 g/mL in the U.S. and is equal to 2 mEq/mL of potassium chloride. We have affixed the following sticker with this information on the carton for the imported product.

• The ampule label of Aguettant's product is in French without English translation. However, the carton and the prescribing information for Aguettant's product is translated into English. Institutions should develop a strategy, which may include labeling the ampules with key information, to ensure safe use of the product.
• Aguettant's product does not contain a barcode. Institutions should manually input the product into their systems. Alternative procedures should be followed to assure that the correct drug product is being used and administered to individual patients.
• Inspect the solution visually for particulate matter and discoloration prior to administration.
• The imported product is packaged in polypropylene 10 mL ampules. To use the ampule, hold it upright, twist off the cap, and withdraw the solution using a syringe.

A side by side comparison of the key differences in the labeling between the FDA-approved product and the imported product is displayed in the product comparison table at the end of this letter.

Please refer to the package insert for the FDA-approved Potassium Chloride for Injection Concentrate, USP drug product for full prescribing information.
