The FDA has approved a subcutaneously administered 20% solution of human immune globulin (Cuvitru – Shire) for replacement therapy in patients ≥2 years old with a primary humoral immunodeficiency. Hizentra (CSL Behring), another subcutaneously administered 20% immune globulin solution, was approved in 2010 for the same indication. The IgG component of Cuvitru is similar to that of Gammagard Liquid and HyQvia, two subcutaneously administered 10% immune globulin formulations also manufactured by Shire and approved for treatment of primary...

The FDA has approved fostamatinib disodium hexahydrate (Tavalisse – Rigel), the first spleen tyrosine kinase (SYK) inhibitor, for oral treatment of thrombocytopenia in adults with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment.

The FDA has approved Duaklir Pressair (Circassia), a fixed-dose combination of the long-acting muscarinic antagonist (LAMA) aclidinium bromide and the longacting beta₂-adrenergic agonist (LABA) formoterol fumarate, for maintenance treatment of chronic obstructive pulmonary disease (COPD). Aclidinium/formoterol is the fifth LAMA/LABA combination to be approved in the US for this indication.

The FDA has approved peanut allergen powder-dnfp (Palforzia – Aimmune) for use as oral immunotherapy to mitigate allergic reactions, including anaphylaxis, caused by accidental peanut exposure in patients with a confirmed peanut allergy. It is the first drug to be approved in the US for this indication; Viaskin Peanut, an immunotherapy patch, is under FDA review for the same indication.

The centuries-old anti-inflammatory drug colchicine (Colcrys, and others) is FDA-approved for prophylaxis and treatment of gout flares and for treatment of familial Mediterranean fever. It is also used off-label to treat pericarditis, and in recent years has been investigated for reduction of cardiovascular risk in patients with coronary artery disease (CAD).

The injectable glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide (Ozempic – Novo Nordisk) has been approved by the FDA to reduce the risk of sustained eGFR decline, end-stage kidney disease, and cardiovascular death in adults with type 2 diabetes and chronic kidney disease (CKD). It is the first GLP-1 receptor agonist to be approved in the US for this indication.

Atopic dermatitis (AD; also known as eczema) is frequently associated with other atopic disorders such as allergic rhinitis, asthma, and food allergy. It commonly presents in infancy and early childhood and has a relapsing course, often improving by adolescence, but sometimes persisting into (or first appearing in) adulthood or even old age.

The tables in this article list drugs used for treatment of cancer in the USA and Canada and their major adverse effects. The choice of drugs in Table I is based on the opinions of Medical Letter consultants. Some drugs are listed for indications for which they have not been approved by the US Food and Drug Administration. In some cases, such as elderly patients or those with many co-morbid illnesses, the regimen of choice might not be suitable. For many of the cancers listed, surgery and/or radiation therapy may be the treatment of choice or may also be part of the management. Anticancer...

Pravastatin (Pravachol - Bristol-Myers Squibb) and simvastatin (Zocor - Merck), two new inhibitors of cholesterol synthesis similar to lovastatin (Mevacor - Merck), have been marketed in Canada and several European countries and may soon be available in the USA for treatment of high plasma cholesterol concentrations. Drugs already marketed here for this indication were recently reviewed in The Medical Letter (Volume 33, page 1, January 11, 1991).

Since the last Medical Letter article on this subject (volume 25, page 54, 1983), transplantation of various organs has become routine, but problems of supply and demand have persisted. The United Network for Organ Sharing (UNOS), which has contracted with the federal government to maintain a list of patients waiting for transplantation and a registry of patients who have received an organ, reports that 18,251 patients received an organ transplant in 1994, and as of June 1995 more than 40,000 patients were waiting for one.
