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...

The FDA has approved taliglucerase alfa (ta lee gloo´ se rays; Elelyso – Pfizer/Protalix), a recombinant form of glucocerebrosidase, for treatment of adults with Type 1 Gaucher disease. These patients have a genetic deficiency of the lysosomal enzyme glucocerebrosidase that leads to accumulation of glucosylceramide in the lysosomes of reticuloendothelial cells, primarily in the liver, spleen and bone marrow.1Taliglucerase is the third form of the enzyme to become available in the US. Imiglucerase (Cerezyme) and velaglucerase (Vpriv) are produced in mammalian cell lines. Taliglucerase is...

Gallium nitrate (Ganite - Fujisawa, USA), originally an anticancer drug, was recently marketed for treatment of cancer-associated hypercalcemia that has not responded to hydration. Other drugs used for treatment of hypercalcemia include furosemide (Lasix, and others), the bisphosphonate etidronate (Didronel IV), calcitonin (Calcimar), and plicamycin (Mithracin, formerly mithramycin) (RAB Schaiff et al, Clin Pharm, 8:108, 1989). Newer bisphosphonates are available in Europe.

High-dose chemotherapy, with or without total body radiation, followed by bone marrow transplantation to restore bone marrow function has been used widely in the treatment of malignant diseases in recent years (Medical Letter, 34:79, 1992; 37:25, 1995). Now, however, instead of using bone marrow itself to restore function destroyed by chemotherapy and radiation, many centers infuse hematopoietic stem cells harvested from peripheral blood. Most stem cell transplants have been autologous; allogeneic stem cells have been tried in a small number of patients (WI Bensinger et al, Blood,...

Recombinant human α-L-iduronidase (laronidase; Aldurazyme BioMarin/Genzyme), an orphan drug, has been approved by the FDA for enzyme replacement therapy in mucopolysaccharidosis (MPS) type I, a lysosomal storage disorder caused by deficiency of the enzyme. This review describes the disease, treatment, adverse effects and cost.

The FDA has approved lutetium Lu 177 dotatate (Lutathera – Advanced Accelerator Applications), a radiolabeled somatostatin analog, for treatment of somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEPNETs) in adults.

Sacituzumab govitecan-hziy (Trodelvy – Gilead) has been approved for treatment of unresectable locally advanced or metastatic hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer in adults who received prior endocrine therapy and ≥2 additional systemic therapies for metastatic disease. It was previously approved for treatment-refractory metastatic triplenegative breast cancer and for treatment of locally advanced or metastatic urothelial cancer in adults who received platinum-based chemotherapy and a programmed death receptor-1...

Atezolizumab (Tecentriq – Genentech), an immune checkpoint inhibitor, has been approved by the FDA for treatment of unresectable or metastatic alveolar soft part sarcoma (ASPS) in patients ≥2 years old. It was previously approved for treatment of non-small cell lung cancer, small cell lung cancer, hepatocellular cancer, and melanoma (see Table 1). Atezolizumab is the first drug to be approved in the US for treatment of ASPS. ASPS is a rare disorder that affects mostly adolescents and young adults; <1% of soft tissue sarcomas are ASPS.

Zolbetuximab-clzb (Vyloy – Astellas), a claudin 18.2 (CLDN18.2)-directed cytolytic antibody, has been approved by the FDA for use in combination with fluoropyrimidine- and platinum-containing chemotherapy for first-line treatment of locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric or gastroesophageal junction (GEJ) adenocarcinoma in patients who have CLDN18.2-positive tumors. It is the first monoclonal antibody to be approved in the US that selectively targets CLDN18.2.

The FDA has approved reslizumab (Cinqair – Teva), a humanized interleukin-5 (IL-5) antagonist monoclonal antibody, for add-on maintenance treatment of severe asthma in adults who have an eosinophilic phenotype. It is the second IL-5 antagonist to be approved in the US; mepolizumab (Nucala) was approved for the same indication in 2015.
