FDA Approves First CGT Generic Drugs
FDA has used its new Competitive Generic Therapy (CGT) designation to approve several strengths of Apotex’ potassium chloride oral solution. An agency statement says the CGT pathway was created to expedite the development and review of a generic drug for products that lack competition. Potassium chloride is an oral treatment indicated for treating and preventing hypokalemia in patients who are on diuretics, and when dietary management with potassium-rich foods is insufficient or diuretic dose reduction is not possible, the statement says.
Under authority of a provision in the 2017 FDA Reauthorization Act, the agency can designate a drug as a CGT if there is inadequate generic competition for it, meaning there is not more than one approved drug in the active section of the Orange Book.
Applicants for drugs that receive a CGT designation may receive review enhancements and expedited review of their ANDAs. They also are eligible for 180 days of marketing exclusivity if they are the first approved applicant for their CGT and meet certain other conditions. Apotex’ potassium chloride oral solution products approved under the CGT are eligible for marketing exclusivity, FDA says. Under a special forfeiture rule for CGTs, the applicant must commercially market the CGT within 75 days after approval of its ANDA or forfeit its exclusivity.
