The FDA has approved Semglee (Mylan), an insulin glargine product similar to Lantus, for treatment of type 1 diabetes in children and adults and type 2 diabetes in adults. Semglee is the second "follow-on" insulin glargine product to become available in the US; Basaglar, which is also similar to Lantus, was the first. Lantus is a recombinant analog of human insulin that forms microprecipitates in subcutaneous tissue, prolonging its duration of action to a mean of about 24 hours with no pronounced peak effect.

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...

The FDA has approved cemiplimab-rwlc (Libtayo – Regeneron), an immune checkpoint inhibitor, for use in combination with platinum-based chemotherapy for first-line treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) in adults with no epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), or ROS1 aberrations and who are not candidates for surgical resection or chemoradiation. The drug was previously approved for first-line treatment of NSCLC in patients whose tumors have high PD-L1 expression and no genomic tumor aberrations....

The FDA has approved vorasidenib (Voranigo – Servier), an oral isocitrate dehydrogenase (IDH) inhibitor, for treatment of grade 2 astrocytoma or oligodendroglioma in patients ≥12 years old with an IDH1 or IDH2 mutation. It is the first systemic treatment to be approved in the US for this indication.

With the possibility that chemical weapons may be used against United States armed forces in the Persian Gulf, the military has taken steps to protect our troops against poison gas, particularly ''nerve agents';'; (MA Dunn and FR Sidell, JAMA, 262:649, 1989).

Chromium is marketed as a dietary supplement, usually containing 20-500 mcg of a chromium salt. It has been promoted for weight loss, muscle building, and for prevention and treatment of diabetes, among other claims. As a dietary supplement, chromium can be sold without proof of efficacy or safety.

The FDA has approved the immune checkpoint inhibitor pembrolizumab (Keytruda – Merck), a programmed death receptor-1 (PD-1) inhibitor, for first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) that highly expresses programmed death-ligand 1 (PD-L1) and has no epidermal growth factor receptor (EGFR) mutations or anaplastic lymphoma kinase (ALK) translocations. About 25% of patients with advanced NSCLC have tumors with high levels of PD-L1 expression (PD-L1 expressed on ≥50% of tumor cells). Pembrolizumab was approved earlier for treatment...

Now that glucosamine and chondroitin, 2 favorite over-the-counter remedies for painful osteoarthritis (OA) of the knee, have been at least somewhat discredited, some patients will be asking about alternatives. One of these is periodic intra-articular injection of a corticosteroid or hyaluronic acid preparation.

The FDA has approved a new Japanese encephalitis vaccine (Ixiaro - Intercell/Novartis). It will replace JEVax (Sanofi Pasteur), which has had tolerability and safety problems and is no longer being manufactured.

At the beginning of this year, The Medical Letter reviewed Monoclate (Armour), a new, highly purified antihemophilic factor (AHF) prepared by immunoaffinity chromatography (Medical Letter, 30:1, 1988). Monoclate is more highly purified than older Factor VIII concentrates, but whether the combination of monoclonal antibody purification and dry heat used in preparing Monoclate will be adequate to prevent transmission of hepatitis and HIV infection remains to be established. Twenty-eight patients previously untreated with Factor VIII concentrate who have received Monoclate for periods...
