  • In Brief: Jadenu - A New Formulation of Deferasirox for Iron Overload
           (online only)
    • Authors: admin
      Abstract: Date:  April 25, 2016 Issue #:  1493 Summary:  The FDA has approved an oral tablet formulation of deferasirox (Jadenu [ jade' new] – Novartis) for once-daily treatment of chronic iron overload due to blood transfusions (transfusional hemosiderosis) in patients ≥2 years old or chronic iron overload in patients ≥10 years old with non-transfusion-dependent thalassemia syndromes. A once-daily, oral tablet for suspension formulation of deferasirox (Exjade) was approved in 2005 for the same indications.1 Jadenu and Exjade are the only once-daily oral formulations for iron chelation available in the US.

      No new clinical trials were required for approval of Jadenu, which was based on earlier clinical trials with Exjade. The most common adverse effects reported with use of deferasirox in clinical trials were diarrhea, vomiting, nausea, abdominal pain, rash, neutropenia, and increases in serum creatinine. Severe skin reactions, including Stevens-Johnson syndrome and erythema multiforme, have been reported rarely. Hearing loss and ocular disturbances, including cataracts, have been reported with deferasirox; patients taking the drug should have annual auditory and ophthalmic exams. Gastrointestinal ulceration and hemorrhage and renal and hepatic toxicity have also occurred.

  • In Brief: Cholic Acid (Cholbam) for Bile Acid Synthesis Disorders
    • Authors: admin
      Abstract: Date:  April 25, 2016 Issue #:  1493 Summary:  The FDA has approved oral cholic acid (Cholbam – Retrophin) for treatment of children and adults with bile acid synthesis disorders caused by single enzyme defects and for adjunctive treatment of peroxisomal disorders such as Zellweger spectrum disorders in patients who have liver disease, steatorrhea, or complications from fat-soluble vitamin malabsorption. Patients with these rare inborn errors of bile acid metabolism cannot synthesize primary bile acids such as cholic acid, resulting in reduced bile flow, decreased absorption of fat and fat-soluble vitamins, and development of liver disease, which can be fatal. Cholbam is the first drug to be approved in the US for these indications.

      FDA approval was based on a long-term, single-arm clinical trial, an extension of that trial, and case reports in a total of 77 patients with bile acid synthesis disorders and 34 patients with peroxisomal disorders. Administration of cholic acid appeared to decrease hepatic injury and increase height and weight; 67% of patients with bile acid synthesis disorders and 42% of those with peroxisomal disorders treated in the clinical trials survived for more than 3 years.1 Some of these survivors have been treated successfully for more than 20 years. Diarrhea has been the most common adverse effect.

      Cholbam is available in 50- and 250-mg capsules. The usual dosage is 10-15 mg/kg taken once daily or in two divided doses. The cost of 30 days' treatment for a 50-kg patient at a daily dose of 10 mg/kg is about $50,000.2

  • In Brief: New Recommendations for Use of Metformin in Renal Impairment
    • Authors: admin
      Abstract: Date:  April 25, 2016 Issue #:  1493 Summary:  The FDA has required labeling changes that replace serum creatinine (SCr) with estimated glomerular filtration rate (eGFR) as the parameter used to determine the appropriateness of treatment with the biguanide metformin (Glucophage, and others) in patients with renal impairment. These changes will allow more patients with mild to moderate renal impairment to receive metformin, which is generally the first drug prescribed for treatment of type 2 diabetes.

      Metformin was previously contraindicated in women with a SCr level ≥1.4 mg/dL and in men with a SCr level ≥1.5 mg/dL, but use of SCr as a surrogate indicator tends to underestimate renal function in certain populations (e.g., younger patients, men, black patients, patients with greater muscle mass). The calculation of eGFR takes into account age, race, and sex, as well as SCr level, providing a more accurate assessment of kidney function. A literature review summarized in an FDA Drug Safety Communication concluded that, based on eGFR, metformin is safe to use in patients with mild renal impairment and in some patients with moderate renal impairment.1

      The eGFR should be calculated before patients begin treatment with metformin and at least annually thereafter. Metformin is now contraindicated in patients with an eGFR <30 mL/min/1.73 m2, and starting treatment with the drug in patients with an eGFR between 30 and 45 mL/min/1.73 m2 is not recommended. If the eGFR falls below 45 mL/min/1.73 m2 in a patient already taking metformin, the benefits and risks of continuing treatment should be assessed. Metformin should be not be administered for 48 hours after an iodinated contrast imaging procedure in patients with an eGFR <60 mL/min/1.73 m2 or a history of liver disease, alcoholism, or heart failure, or in those receiving intra-arterial contrast, and the eGFR should be re-evaluated before treatment is restarted.
