The FDA has approved ofatumumab (Arzerra – GlaxoSmithKline), a human anti-CD20 monoclonal antibody, for treatment of patients with chronic lymphocytic leukemia (CLL) refractory to fludarabine (Fludara, and others) and alemtuzumab (Campath). It is the second anti-CD20 antibody approved for treatment of CLL; rituximab (Rituxan), a chimeric murine/human antibody, was the first.

(Med Lett Drugs Ther 2008; 50:91) In the Clinical Studies section, the complete response rate with chlorambucil for CLL was 2% (not 24%).

Bendamustine HCl (Treanda - Cephalon), an unusual DNA-alkylating agent that has been used in Europe for many years to treat lymphoma, has now been approved by the FDA for treatment of chronic lymphocytic leukemia (CLL) and non-Hodgkin's lymphoma (NHL).

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 drugs and their adverse effects are listed in Table II on page 46. A partial list of brand names appears on page 52.

Pentostatin (2'-deoxycoformycin; DCF; - Parke-Davis), a purine analog, was recently approved by the US Food and Drug Administration (FDA) for treatment of hairy-cell leukemia resistant to interferon alfa (Intron A; Roferon-A). is a rare (500 cases/year in the USA) form of chronic lymphocytic leukemia. Acutely ill patients may respond rapidly to interferon, but the drug is rarely curative. Another purine analog, 2-chlorodeoxyadenosine (CdA; Leustatin - Ortho Biotech), may also be approved soon for treatment of hairy-cell leukemia (JD Piro, Blood, 79:843, 1992). Fludarabine (Fludara -Medical Letter, 33:89, 1991), a third purine analog, is approved for treatment of refractory chronic lymphocytic leukemia. All three drugs are investigational for use in non-Hodgkin's lymphomas.

Fludarabine phosphate (Fludara - Berlex), an analog of vidarabine (Vira-A), was recently approved by the U.S. Food and Drug Administration for treatment of patients with refractory chronic lymphocytic leukemia (CLL). The drug has not yet been marketed but is still available, as it has been for two years, through the National Cancer Institute.
