The FDA has approved the oral tyrosine kinase inhibitor repotrectinib (Augtyro – BMS) for treatment of locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC) in adults. Repotrectinib is the third oral tyrosine kinase inhibitor to be approved for this indication in the US; crizotinib (Xalkori) and entrectinib (Rozlytrek) were approved earlier.

The FDA has approved use of dinutuximab (Unituxin [yoo ni tux' in] – United Therapeutics) in combination with interleukin-2 (IL-2), granulocyte-macrophage colony-stimulating factor (GM-CSF), and isotretinoin for treatment of children with high-risk neuroblastoma who previously responded to first-line therapies. Dinutuximab is a monoclonal antibody that binds to GD2, a glycolipid that is overexpressed on the surface of neuroblastoma cells.1Dinutuximab received a priority review and orphan drug designation. Approval was based on the results of an open-label trial in 226 patients with high-risk...

A topical formulation of the antimetabolite mitomycin (Mitosol – Mobius Therapeutics) has been approved by the FDA for adjunctive use in glaucoma surgery to reduce scarring. Compounding pharmacies have supplied the drug off-label for this purpose for many years.

Mitoxantrone (Novantrone - Lederle), a synthetic anthracene related to the anthracyclines doxorubicin (Adriamycin) and daunorubicin (Cerubidine), has now been marketed in the USA to be used in combination with other drugs for initial treatment of acute nonlymphocytic leukemia in adults.

Doripenem (Doribax - Ortho-McNeil Janssen), an intravenous (IV) carbapenem antibiotic with a spectrum of activity similar to that of imipenem and meropenem, has been approved by the FDA for treatment of complicated intra-abdominal and urinary tract infections. Use of doripenem for treatment of nosocomial pneumonia, including ventilator-associated pneumonia, is still under FDA review.

The FDA has approved a 0.016% gel formulation of the nitrogen mustard mechlorethamine (Valchlor – Actelion) for second-line topical treatment of patients with stage IA or IB mycosis fungoides, the most common type of cutaneous T-cell lymphoma. Topical nitrogen mustard has been used off-label for decades for this indication, usually as a pharmacy-compounded ointment, but no clinical trials evaluating its efficacy and safety have been done. Mechlorethamine is also available in an injectable formulation (Mustargen – Recordati) for the same and other indications.FDA approval of Valchlor was...

The FDA has approved Lonsurf (Taiho Oncology), a combination of the thymidine-based nucleoside analog trifluridine and the thymidine phosphorylase inhibitor tipiracil, for oral treatment of metastatic colorectal cancer. Trifluridine is incorporated into DNA, interfering with DNA synthesis and inhibiting cell proliferation. Tipiracil inhibits the metabolism of trifluridine. The combination is only approved for use in patients who were previously treated with a fluoropyrimidine (fluorouracil or capecitabine), oxaliplatin, irinotecan, an anti-VEGF biological such as bevacizumab, and, if the tumor...

The FDA has approved two new drugs for treatment of specific subtypes of acute myeloid leukemia (AML).Vyxeos (Jazz Pharmaceuticals) is a liposomal fixed-dose combination of daunorubicin and cytarabine, the standard drugs used for induction treatment of AML. It is approved for induction and consolidation treatment in adults with newly diagnosed chemotherapy- or radiation-related AML or AML with myelodysplasia-related changes. Patients with these subtypes of AML have a poor prognosis. The rationale for development of the combination was that nano-scale liposomal drug delivery vehicles prolong...

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.

The FDA has approved pralatrexate (Folotyn – Allos), an intravenous (IV) antifolate, for treatment of adults with relapsed or refractory peripheral T-cell lymphoma (PTCL). It is the first drug approved by the FDA specifically for this indication.
