ROCKLAND, Mass. — A redesigned version of an injector pen used to treat infertility is available for distribution in the United States, the manufacturer said Monday.
EMD Serono, a subsidiary of German drug maker Merck KGaA, said that Gonal-f RFF Redi-ject, a disposable, pre-filled pen used for the drug Gonal-f RFF (follitropin alfa), had become available. The Food and Drug Administration approved the redesigned pen in October. Merck KGaA operates in the United States under the name EMD in order to avoid confusion with U.S.-based Merck & Co.
